1.  Outcomes of Xanthogranulomatous cholecystitis in laparoscopic era: A retrospective Cohort study 
INTRODUCTION:
Xanthogranulomatous cholecystitis (XGC) is a rare variant of cholecystitis and reported incidence of XGC varies from different geographic region from 0.7% -9%. Most of the clinicians are not aware of the pathology and less evidence is available regarding the optimal treatment of this less common form of cholecystitis in the present era of laparoscopic surgery.
MATERIALS AND METHODS:
A retrospective cohort study was conducted in a tertiary care university hospital from 1989 to 2009. Histopathologically confirmed XGC study patients (N=27) were compared with non-Xanthogranulomatous cholecystitis (NXGC) control group (N=27). The outcomes variables were operative time, complication rate and laparoscopic to open cholecystectomy conversion rate. The study group (XGC) was further divided in to three sub groups; group I open cholecystectomy (OC), laparoscopic cholecystectomy (LC) and laparoscopic converted to open cholecystectomy (LCO) for comparative analysis to identify the significant variables.
RESULTS:
During the study period 6878 underwent cholecystectomy including open cholecystectomy in 2309 and laparoscopic cholecystectomy in 4569 patients. Histopathology confirmed xanthogranulomatous cholecystitis in 30 patients (0.43% of all cholecystectomies) and 27 patients qualified for the inclusion criterion. Gallbladder carcinoma was reported in 100 patients (1.45%) during the study period and no association was found with XGC. The mean age of patients with XGC was 49.8 year (range: 29-79), with male to female ratio of 1:3. The most common clinical features were abdominal pain and tenderness in right hypochondrium. Biliary colic and acute cholecystitis were the most common preoperative diagnosis. Ultrasonogram was performed in all patients and CT scan abdomen in 5 patients. In study population (XGC), 10 were patients in group I, 8 in group II and 9 in group III. Conversion rate from laparoscopy to open was 53 % (n=9), surgical site infection rate of 14.8% (n=4) and common bile duct injury occurred one patient in open cholecystectomy group (3.7%). Statistically significant differences between group I and group II were raised total leukocyte count: 10.6±3.05 vs. 7.05±1.8 (P-Value 0.02) and duration of surgery in minutes: 248.75±165 vs. 109±39.7 (P-Value 0.04). The differences between group III and group II were duration of surgery in minutes: 208.75±58 vs. 109±39.7 (P-Value 0.03) and duration of symptoms in days: 3±1.8 vs. 9.8±8.8 (P-Value 0.04). The mean hospital stay in group I was 9.7 days, group II 5.6 days and in group III 10.5 days. Two patients underwent extended cholecystectomy based on clinical suspicion of carcinoma. No mortality was observed in this study population. Duration of surgery was higher in XGC group as compared to controls (NXGC) (203±129 vs.128±4, p-value=0.008) and no statistically significant difference in incidence proportion of operative complication rate were observed among the group (25.9% vs. 14.8%, p-value=0.25. Laparoscopic surgery was introduced in 1994 and 17 patients underwent laparoscopic cholecystectomy and higher conversion rate from laparoscopic to open cholecystectomy was observed in 17 study group (XGC) as compared to 27 Control group (NXGC) 53%vs.3.3% with P-value of < 0.023.
CONCLUSION:
XGC is a rare entity of cholecystitis and preoperative diagnosis is a challenging task. Difficult dissection was encountered in open as well in laparoscopic cholecystectomy with increased operation time. Laparoscopic cholecystectomy was carried out with high conversion rate to improve the safety of procedure. Per operative clinical suspicion of malignancy was high but no association of XGC was found with gallbladder carcinoma, therefore frozen section is recommended before embarking on radical surgery.

2.  Incidental gallbladder cancer during laparoscopic cholecystectomy: Managing an unexpected finding 
AIM: To evaluate the impact of incidental gallbladder cancer on surgical experience.
METHODS: Between 1998 and 2008 all cases of cholecystectomy at two divisions of general surgery, one university based and one at a public hospital, were retrospectively reviewed. Gallbladder pathology was diagnosed by history, physical examination, and laboratory and imaging studies [ultrasonography and computed tomography (CT)]. Patients with gallbladder cancer (GBC) were further analyzed for demographic data, and type of operation, surgical morbidity and mortality, histopathological classification, and survival. Incidental GBC was compared with suspected or preoperatively diagnosed GBC. The primary endpoint was disease-free survival (DFS). The secondary endpoint was the difference in DFS between patients previously treated with laparoscopic cholecystectomy and those who had oncological resection as first intervention.
RESULTS: Nineteen patients (11 women and eight men) were found to have GBC. The male to female ratio was 1:1.4 and the mean age was 68 years (range: 45-82 years). Preoperative diagnosis was made in 10 cases, and eight were diagnosed postoperatively. One was suspected intraoperatively and confirmed by frozen sections. The ratio between incidental and nonincidental cases was 9/19. The tumor node metastasis stage was: pTis (1), pT1a (2), pT1b (4), pT2 (6), pT3 (4), pT4 (2); five cases with stage Ia (T1 a-b); two with stage Ib (T2 N0); one with stage IIa (T3 N0); six with stage IIb (T1-T3 N1); two with stage III (T4 Nx Nx); and one with stage IV (Tx Nx Mx). Eighty-eight percent of the incidental cases were discovered at an early stage (≤ II). Preoperative diagnosis of the 19 patients with GBC was: GBC with liver invasion diagnosed by preoperative CT (nine cases), gallbladder abscess perforated into hepatic parenchyma and involving the transversal mesocolon and hepatic hilum (one case), porcelain gallbladder (one case), gallbladder adenoma (one case), and chronic cholelithiasis (eight cases). Every case, except one, with a T1b or more advanced invasion underwent IVb + V wedge liver resection and pericholedochic/hepatoduodenal lymphadenectomy. One patient with stage T1b GBC refused further surgery. Cases with Tis and T1a involvement were treated with cholecystectomy alone. One incidental case was diagnosed by intraoperative frozen section and treated with cholecystectomy alone. Six of the nine patients with incidental diagnosis reached 5-year DFS. One patient reached 38 mo survival despite a port-site recurrence 2 years after original surgery. Cases with non incidental diagnosis were more locally advanced and only two patients experienced 5-year DFS.
CONCLUSION: Laparoscopic cholecystectomy does not affect survival if implemented properly. Reoperation should have two objectives: R0 resection and clearance of the lymph nodes.

3.  Management of massive haemobilia in an Indian hospital 
The Indian Journal of Surgery  2008;70(6):288-295.
Introduction
Massive haemobilia carries a mortality of 25% in most reports. Although previously it was mainly due to road accidents or homicidal attempts it is now more often due to iatrogenic trauma like percutaneous liver biopsy and biliary drainage. However the management protocol is not established and there have been few reports of this serious condition from India.
Aim
To review the causes of massive haemobilia and outline its management in an Indian hospital.
Patients and methods
We retrospectively analysed the records of 20 consecutive patients with massive haemobilia (blood requirement more than 1400 ml/day) admitted to our department over six years from a prospectively maintained database. There were 10 males and 10 females who had a mean age of 43 (range 15–65) years.
Results
Haemobilia accounted for 9 percent of patients admitted with upper gastrointestinal bleeding who were seen over this period. The commonest cause was iatrogenic (11) including laparoscopic cholecystectomy (6), Whipple’s operation, endoscopic retrograde cholangiography (ERC), percutaneous transhepatic cholangiography (PTC), hepatic stone extraction and removal of biliary stent (1 each). The others had accidental trauma (4), visceral aneurysms (2), biliary stones (2) and chronic pancreatitis (1). The commonest clinical presentation was massive gastrointestinal bleeding. The dual phase computed tomography (CT) scan correctly identified the site of bleeding and other associated conditions in all the 11 patients in whom it was done. Conventional angiography was done in 8 patients with transarterial embolisation (TAE) being attempted in 6 and successful in 2 patients. Operations were performed in 18 patients for the following indications — failure of angiographic embolisation (6), failure of endoscopic sclerotherapy (EST) (1), duodenal erosion (2), portal biliopathy (1), haemoperitoneum (1), bile leak (1), pseudocyst (1), liver necrosis (1) and other hepatobiliary conditions (4). The surgical procedures to control bleeding were ligation of aneurysms (8), repair of the hepatic artery (4), right hepatectomy (3), lienorenal shunt, cholecystectomy and under-running of the duodenal papilla (1 each). The overall mortality was 4 patients (20 percent). There was no mortality in patients with bleeding aneurysms; the mortality being significantly higher in patients with non-aneurysmal bleeding (p=0.0049: Fishers’ exact test).
Conclusions
In our experience haemobilia was usually due to an iatrogenic cause with a pseudoaneurysm following a diagnostic or therapeutic intervention(most often laparoscopic cholecystectomy) being the commonest aetiology. A dual phase CT scan accurately identified the site of bleeding. Angiographic embolisation often failed to stop bleeding and mortality was significantly higher in patients with non-aneurysmal bleeding. We should perhaps consider early surgery for haemobilia once the bleeding site has been localised by CT scan.

4.  Percutaneous transhepatic gall bladder drainage: a better initial therapeutic choice for patients with gall bladder perforation in the emergency department 
Emergency Medicine Journal : EMJ  2007;24(12):836-840.
Objectives
To investigate clinical features and outcomes in patients with acute cholecystitis with gall bladder perforation receiving open cholecystectomy or percutaneous transhepatic gall bladder drainage in the emergency department.
Methods
From 1996 through 2005, 33 patients with non‐traumatic gall bladder perforation, among 585 patients with acute cholecystitis, were enrolled. Patients were divided into two groups: open cholecystectomy in 16 patients and percutaneous transhepatic gall bladder drainage in 17 patients. Medical records, including demographic data, past history of systemic diseases or gallbladder stones, initial clinical presentations, laboratory data, physical status, therapeutic interventions, and outcomes, were analysed.
Results
Mean patient age was 72.6 years (range 54–92 years). 28 patients (84.8%) were male. Median time of symptom onset before emergency department diagnosis was 5 days (range 0.5–30 days). Estimated incidence of gall bladder perforation was 5.6% (33/585). 27 patients (81.8%) had gallstones operatively or in image studies. All patients had either right upper quadrant pain/tenderness or epigastric pain/tenderness. Only 9 (27.3%) patients had positive Murphy's sign. Six patients in the percutaneous transhepatic gall bladder drainage group received further open cholecystectomy. Overall mortality was 24.2% (8/33). The direct cause of death was disease related sepsis in all patients. Patients receiving percutaneous transhepatic gall bladder drainage had a higher survival rate than those receiving open cholecystectomy (100% vs 50%, p<0.001). No differences in complications and length of hospital stay of survivors were observed between groups.
Conclusions
In this study, we delineated clinical features of patients with gall bladder perforation. Better clinical outcome is observed for percutaneous transhepatic gall bladder drainage, and this is suggested as an initial therapeutic choice, especially in high risk patients who are likely to need surgery.

5.  Gallbladder cancer: epidemiology and outcome 
Clinical Epidemiology  2014;6:99-109.
Gallbladder cancer, though generally considered rare, is the most common malignancy of the biliary tract, accounting for 80%–95% of biliary tract cancers. An early diagnosis is essential as this malignancy progresses silently with a late diagnosis, often proving fatal. Its carcinogenesis follows a progression through a metaplasia–dysplasia–carcinoma sequence. This comprehensive review focuses on and explores the risks, management, and outcomes for primary gallbladder carcinoma. Epidemiological studies have identified striking geographic and ethnic disparities – inordinately high occurrence in American Indians, elevated in Southeast Asia, yet quite low elsewhere in the Americas and the world. Age, female sex, congenital biliary tract anomalies, and a genetic predisposition represent important risk factors that are immutable. Environmental triggers play a critical role in eliciting cancer developing in the gallbladder, best exemplified by cholelithiasis and chronic inflammation from biliary tract and parasitic infections. Mortality rates closely follow incidence; those countries with the highest prevalence of gallstones experience the greatest mortality from gallbladder cancer. Vague symptoms often delay the diagnosis of gallbladder cancer, contributing to its overall progression and poor outcome. Surgery represents the only potential for cure. Some individuals are fortunate to be incidentally found to have gallbladder cancer at the time of cholecystectomy being performed for cholelithiasis. Such an early diagnosis is imperative as a late presentation connotes advanced staging, nodal involvement, and possible recurrence following attempted resection. Overall mean survival is a mere 6 months, while 5-year survival rate is only 5%. The dismal prognosis, in part, relates to the gallbladder lacking a serosal layer adjacent to the liver, enabling hepatic invasion and metastatic progression. Improved imaging modalities are helping to diagnose patients at an earlier stage. The last decade has witnessed improved outcomes as aggressive surgical management and preoperative adjuvant therapy has helped prolong survival in patients with gallbladder cancer. In the future, the development of potential diagnostic markers for disease will yield screening opportunities for those at risk either with ethnic susceptibility or known anatomic anomalies of the biliary tract. Meanwhile, clarification of the value of prophylactic cholecystectomy should provide an opportunity for secondary prevention. Primary prevention will arrive once the predictive biomarkers and environmental risk factors are more clearly identified.

6.  Methods and timing of biliary drainage for acute cholangitis: Tokyo Guidelines 
Biliary drainage is a radical method to relieve cholestasis, a cause of acute cholangitis, and takes a central part in the treatment of acute cholangitis. Emergent drainage is essential for severe cases, whereas patients with moderate and mild disease should also receive drainage as soon as possible if they do not respond to conservative treatment, and their condition has not improved. Biliary drainage can be achieved via three different routes/procedures: endoscopic, percutaneous transhepatic, and open methods. The clinical value of both endoscopic and percutaneous transhepatic drainage is well known. Endoscopic drainage is associated with a low morbidity rate and shorter duration of hospitalization; therefore, this approach is advocated whenever it is applicable. In endoscopic drainage, either endoscopic nasobiliary drainage (ENBD) or tube stent placement can be used. There is no significant difference in the success rate, effectiveness, and morbidity between the two procedures. The decision to perform endoscopic sphincterotomy (EST) is made based on the patient’s condition and the number and diameter of common bile duct stones. Open drainage, on the other hand, should be applied only in patients for whom endoscopic or percutaneous transhepatic drainage is contraindicated or has not been successfully performed. Cholecystectomy is recommended in patients with gallbladder stones, following the resolution of acute cholangitis with medical treatment, unless the patient has poor operative risk factors or declines surgery.

7.  Flowcharts for the diagnosis and treatment of acute cholangitis and cholecystitis: Tokyo Guidelines 
Diagnostic and therapeutic strategies for acute biliary inflammation/infection (acute cholangitis and acute cholecystitis), according to severity grade, have not yet been established in the world. Therefore we formulated flowcharts for the management of acute biliary inflammation/infection in accordance with severity grade. For mild (grade I) acute cholangitis, medical treatment may be sufficient/appropriate. For moderate (grade II) acute cholangitis, early biliary drainage should be performed. For severe (grade III) acute cholangitis, appropriate organ support such as ventilatory/circulatory management is required. After hemodynamic stabilization is achieved, urgent endoscopic or percutaneous transhepatic biliary drainage should be performed. For patients with acute cholangitis of any grade of severity, treatment for the underlying etiology, including endoscopic, percutaneous, or surgical treatment should be performed after the patient’s general condition has improved. For patients with mild (grade I) cholecystitis, early laparoscopic cholecystectomy is the preferred treatment. For patients with moderate (grade II) acute cholecystitis, early laparoscopic or open cholecystectomy is preferred. In patients with extensive local inflammation, elective cholecystectomy is recommended after initial management with percutaneous gallbladder drainage and/or cholecystostomy. For the patient with severe (grade III) acute cholecystitis, multiorgan support is a critical part of management. Biliary peritonitis due to perforation of the gallbladder is an indication for urgent cholecystectomy and/or drainage. Delayed elective cholecystectomy may be performed after initial treatment with gallbladder drainage and improvement of the patient’s general medical condition.

8.  Importance of early diagnosis of pancreaticobiliary maljunction without biliary dilatation 
AIM: To clarify the strategy for early diagnosis of pancreaticobiliary maljunction (PBM) without biliary dilatation and to pathologically examine gallbladder before cancer develops.
METHODS: The anatomy of the union of the pancreatic and bile ducts was assessed by using endoscopic retrograde cholangiopancreatography (ERCP). Patients with a long common channel in which communication between the pancreatic and bile ducts was maintained even during sphincter contraction were diagnosed as having PBM. Of these, patients in which the maximal diameter of the bile duct was less than 10 mm were diagnosed with PBM without biliary dilatation. The process of diagnosing 54 patients with PBM without biliary dilatation was retrospectively investigated. Histopathological analysis of resected gallbladder specimens from 8 patients with PBM without biliary dilatation or cancer was conducted.
RESULTS: Thirty-six PBM patients without biliary dilatation were diagnosed with gallbladder cancer after showing clinical symptoms such as abdominal or back pain (n = 16) or jaundice (n = 12). Radical surgery for gallbladder cancer was only possible in 11 patients (31%) and only 4 patients (11%) survived for 5 years. Eight patients were suspected as having PBM without biliary dilatation from the finding of gallbladder wall thickening on ultrasound and the diagnosis was confirmed by ERCP and/or magnetic resonance cholangiopancreatography (MRCP). The median age of these 8 patients was younger by a decade than PBM patients with gallbladder cancer. All 8 patients underwent prophylactic cholecystectomy and bile duct cancer has not occurred. Wall thickness and mucosal height of the 8 resected gallbladders were significantly greater than controls, and hyperplastic changes, hypertrophic muscular layer, subserosal fibrosis, and adenomyomatosis were detected in 7 (88%), 5 (63%), 7 (88%) and 5 (63%) patients, respectively. Ki-67 labeling index was high and K-ras mutation was detected in 3 of 6 patients.
CONCLUSION: To detect PBM without biliary dilatation before onset of gallbladder cancer, we should perform MRCP for individuals showing increased gallbladder wall thickness on ultrasound.

9.  Preoperative biliary drainage for biliary tract and ampullary carcinomas 
We posed six clinical questions (CQ) on preoperative biliary drainage and organized all pertinent evidence regarding these questions. CQ 1. Is preoperative biliary drainage necessary for patients with jaundice? The indications for preoperative drainage for jaundiced patients are changing greatly. Many reports state that, excluding conditions such as cholangitis and liver dysfunction, biliary drainage is not necessary before pancreatoduodenectomy or less invasive surgery. However, the morbidity and mortality of extended hepatectomy for biliary cancer is still high, and the most common cause of death is hepatic failure; therefore, preoperative biliary drainage is desirable in patients who are to undergo extended hepatectomy. CQ 2. What procedures are appropriate for preoperative biliary drainage? There are three methods of biliary drainage: percutaneous transhepatic biliary drainage (PTBD), endoscopic nasobiliary drainage (ENBD) or endoscopic retrograde biliary drainage (ERBD), and surgical drainage. ERBD is an internal drainage method, and PTBD and ENBD are external methods. However, there are no reports of comparisons of preoperative biliary drainage methods using randomized controlled trials (RCTs). Thus, at this point, a method should be used that can be safely performed with the equipment and techniques available at each facility. CQ 3. Which is better, unilateral or bilateral biliary drainage, in malignant hilar obstruction? Unilateral biliary drainage of the future remnant hepatic lobe is usually enough even when intrahepatic bile ducts are separated into multiple units due to hilar malignancy. Bilateral biliary drainage should be considered in the following cases: those in which the operative procedure is difficult to determine before biliary drainage; those in which cholangitis has developed after unilateral drainage; and those in which the decrease in serum bilirubin after unilateral drainage is very slow. CQ 4. What is the best treatment for postdrainage fever? The most likely cause of high fever in patients with biliary drainage is cholangitis due to problems with the existing drainage catheter or segmental cholangitis if an undrained segment is left. In the latter case, urgent drainage is required. CQ 5. Is bile culture necessary in patients with biliary drainage who are to undergo surgery? Monitoring of bile cultures is necessary for patients with biliary drainage to determine the appropriate use of antibiotics during the perioperative period. CQ 6. Is bile replacement useful for patients with external biliary drainage? Maintenance of the enterohepatic bile circulation is vitally important. Thus, preoperative bile replacement in patients with external biliary drainage is very likely to be effective when highly invasive surgery (e.g., extended hepatectomy for hilar cholangiocarcinoma) is planned.

10.  Incidental gallbladder carcinoma: our experience 
Il Giornale di Chirurgia  2013;34(5-6):167-169.
Summary:
Aim.
Gallbladder carcinoma is an uncommon cancer with a poor prognosis. In the era of laparoscopic cholecistectomy for treatment of benign diseases incidental gallbladder carcinoma has dramatically increased and now constitutes the major way patients present with gallbladder cancer and allows to detect cancer at early stages with a better prognosis. In this single-center study we report our experience with gallbladder carcinoma incidentally diagnosed during or after laparoscopic colecistectomy performed for cholelithiasis.
Methods
From January 2003 to December 2011 a total of 1193 patients underwent cholecistectomy at General Surgical Unit III of University of Bari. The patients were 458 males and 735 females, mean age was 52 years (range 19–91). In 6 of 1188 patients adenocarcinoma was present in the pathologic specimens (0,5%).
Results
Of 1188 patients in whom laparoscopic cholecistectomy was attempted adenocarcinoma was diagnosed histopathologically in 6 cases (0,5%). There was no suspicion of malignancy to any of them. Intraoperatively, gallbladder wall appeared abnormal in one patients and frozen section analysis revealed adenocarcinoma. In the remaining 5 cases routine histopathological studies revealed the diagnosis of gallbladder carcinoma. One patient had T1 tumor, two had T2 and three had T3 tumor.
Conclusions
In the present study the rate of incidental gallbladder carcinoma was 0,5%, according to the published English language literature. The risk factors widely related to the gallbladder cancer are advanced age and gallstones disease. The therapeutic approach to gallbladder cancer was applied according to the stage of tumor, but in our study this was possible only in two patients with T2 and T3 tumor since high risk and important comorbidities were the main causes for the refusal of 3 patient out of 5. Only the T1 patient underwent simple cholecystectomy. Similar to other reports in this single-center study the diagnosis of incidental gallbladder carcinoma was found to be of 0,5%, thus the diagnosis of gallbladder stones is an indication to the cholecystectomy.

11.  "Extended" radical cholecystectomy for gallbladder cancer: Long-term outcomes, indications and limitations 
AIM: To delineate indications and limitations for "extended" radical cholecystectomy for gallbladder cancer: a procedure which was instituted in our department in 1982.
METHODS: Of 145 patients who underwent a radical resection for gallbladder cancer from 1982 through 2006, 52 (36%) had an extended radical cholecystectomy, which involved en bloc resection of the gallbladder, gallbladder fossa, extrahepatic bile duct, and the regional lymph nodes (first- and second-echelon node groups). A retrospective analysis of the 52 patients was conducted including at least 5 years of follow up. Residual tumor status was judged as no residual tumor (R0) or microscopic/macroscopic residual tumor (R1-2). Pathological findings were documented according to the American Joint Committee on Cancer Cancer Staging Manual (7th edition).
RESULTS: The primary tumor was classified as pathological T1 (pT1) in 3 patients, pT2 in 36, pT3 in 12, and pT4 in 1. Twenty-three patients had lymph node metastases; 11 had a single positive node, 4 had two positive nodes, and 8 had three or more positive nodes. None of the three patients with pT1 tumors had nodal disease, whereas 23 of 49 (47%) with pT2 or more advanced tumors had nodal disease. One patient died during the hospital stay for definitive resection, giving an in-hospital mortality rate of 2%. Overall survival (OS) after extended radical cholecystectomy was 65% at 5 years and 53% at 10 years in all 52 patients. OS differed according to the pT classification (P < 0.001) and the nodal status (P = 0.010). All of 3 patients with pT1 tumors and most (29 of 36) patients with pT2 tumors survived for more than 5 years. Of 12 patients with pT3 tumors, 8 who had an R1-2 resection, distant metastasis, or extensive extrahepatic organ involvement died soon after resection. Of the remaining four pT3 patients who had localized hepatic spread through the gallbladder fossa and underwent an R0 resection, 2 survived for more than 5 years and another survived for 4 years and 2 mo. The only patient with pT4 tumor died of disease soon after resection. Among 23 node-positive patients, 11 survived for more than 5 years, and of these, 10 had a modest degree of nodal disease (one or two positive nodes).
CONCLUSION: Extended radical cholecystectomy is indicated for pT2 tumors and some pT3 tumors with localized hepatic invasion, provided that the regional nodal disease is limited to a modest degree (up to two positive nodes). Extensive pT3 disease, pT4 disease, or marked nodal disease appears to be beyond the scope of this radical procedure.

12.  Comparison of thymidine phosphorylase expression and prognostic factors in gallbladder and bile duct cancer 
BMC Cancer  2010;10:564.
Background
Biliary tract cancers have limitations in information about different location-related pathogenesis and clinico-pathological characteristics. The goal of this study was to investigate anatomical site-related similarities and differences in biliary tract cancers and to assess the expression and clinical significance of functional proteins such as p53, cyclin D1, survivin, thymidine phosphorylase, and ERCC1.
Methods
One hundred and sixty-one patients with biliary tract adenocarcinomas, who underwent curative or palliative surgery in a single institution between October 1994 and December 2003 were evaluated, retrospectively. The level of protein expression of p53, cyclin D1, survivin, thymidine phosphorylase, and ERCC1 was assessed by immunohistochemistry.
Results
With respect to clinico-pathological characteristics, gallbladder cancer was more frequent in women, and bile duct cancer was more common in men. Perineural invasion was more common in bile duct cancer. Recurrence as a distant metastasis was more common in gallbladder cancer. Immunohistochemical analysis revealed that thymidine phosphorylase expression was significantly higher in gallbladder cancer than in bile duct cancer. Positive thymidine phosphorylase and p53 staining were associated with an advanced stage. Differentiation, vascular invasion, perineural invasion, lymphatic invasion, lymph node metastasis, and TNM stage independently predicted poor prognosis in biliary tract cancer. These correlations were seen more clearly in gallbladder cancer. The immunohistochemical staining patterns of p53, cyclin D1, survivin, thymidine phosphorylase, and ERCC1 showed no prognostic significance in biliary tract cancers.
Conclusions
We concluded that gallbladder and bile duct cancers are considered to be separate diseases with different clinico-pathological characteristics and prognostic factors. In addition, we hypothesize that high expression of thymidine phosphorylase by gallbladder cancer results in a higher response rate to capecitabine by gallbladder cancer than bile duct cancer.

13.  Perfidious Gallbladders – A Diagnostic Dilemma with Xanthogranulomatous Cholecystitis 
INTRODUCTION
Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis characterised by marked thickening of the gallbladder wall and dense local adhesions. Pre-operative and intra-operative diagnosis is difficult and it often mimics a gallbladder carcinoma (GBC). Laparoscopic cholecystectomy (LC) is frequently unsuccessful with a high conversion rate. A series of patients with this condition led us to review our experience with XGC and to try to develop a care pathway for its management.
PATIENTS AND METHODS
A retrospective review of the medical records of 1296 consecutive patients who had undergone cholecystectomy between January 2000 and April 2005 at our hospital was performed. Twenty-nine cases of XGC were identified among these cholecystectomies. The clinical, radiological and operative details of these patients have been analysed.
RESULTS
The incidence of XGC was 2.2% in our study. The mean age at presentation was 60.3 years with a female:male ratio of 1.4:1. Twenty-three patients (79%) required an emergency surgical admission at first presentation. In three patients, a GBC was suspected both radiologically and at operation (10.3%), but was later disproved on histology. Seventeen patients (59%) had obstructive jaundice at first presentation and required an endoscopic retrograde cholangiopancreatography (ERCP) before LC. Of these, five had common bile duct stones. Abdominal ultrasound scan showed marked thickening of the gallbladder wall in 16 cases (55%). LC was attempted in 24 patients, but required conversion to an open procedure in 11 patients (46% conversion rate). A total cholecystectomy was possible in 18 patients and a partial cholecystectomy was the choice in 11 (38%). The average operative time was 96 min. Three patients developed a postoperative bile leak, one of whom required ERCP and placement of a biliary stent. The average length of stay in the hospital was 6.3 days.
CONCLUSIONS
Severe xanthogranulomatous cholecystitis often mimics a gallbladder carcinoma. Currently, a correct pre-operative diagnosis is rarely made. With increased awareness and a high index of suspicion, radiological diagnosis is possible. Preoperative counselling of these patients should include possible intra-operative difficulties and the differential diagnosis of gallbladder cancer. Laparoscopic cholecystectomy is frequently unsuccessful and a partial cholecystectomy is often the procedure of choice.

14.  Guidelines for the management of biliary tract and ampullary carcinomas: surgical treatment 
The only curative treatment in biliary tract cancer is surgical treatment. Therefore, the suitability of curative resection should be investigated in the first place. In the presence of metastasis to the liver, lung, peritoneum, or distant lymph nodes, curative resection is not suitable. No definite consensus has been reached on local extension factors and curability. Measures of hepatic functional reserve in the jaundiced liver include future liver remnant volume and the indocyanine green (ICG) clearance test. Preoperative portal vein embolization may be considered in patients in whom right hepatectomy or more, or hepatectomy with a resection rate exceeding 50%–60% is planned. Postoperative complications and surgery-related mortality may be reduced with the use of portal vein embolization. Although hepatectomy and/or pancreaticoduodenectomy are preferable for the curative resection of bile duct cancer, extrahepatic bile duct resection alone is also considered in patients for whom it is judged that curative resection would be achieved after a strict diagnosis of its local extension. Also, combined caudate lobe resection is recommended for hilar cholangiocarcinoma. Because the prognosis of patients treated with combined portal vein resection is significantly better than that of unresected patients, combined portal vein resection may be carried out. Prognostic factors after resection for bile duct cancer include positive surgical margins, especially in the ductal stump; lymph node metastasis; perineural invasion; and combined vascular resection due to portal vein and/or hepatic artery invasion. For patients with suspected gallbladder cancer, laparoscopic cholecystectomy is not recommended, and open cholecystectomy should be performed as a rule. When gallbladder cancer invading the subserosal layer or deeper has been detected after simple cholecystectomy, additional resection should be considered. Prognostic factors after resection for gallbladder cancer include the depth of mural invasion; lymph node metastasis; extramural extension, especially into the hepatoduodenal ligament; perineural invasion; and the degree of curability. Pancreaticoduodenectomy is indicated for ampullary carcinoma, and limited operation is also indicated for carcinoma in adenoma. The prognostic factors after resection for ampullary carcinoma include lymph node metastasis, pancreatic invasion, and perineural invasion.

15.  Routine histopathology of gallbladder after elective cholecystectomy for gallstones: waste of resources or a justified act? 
BMC Surgery  2013;13:26.
Background
Selective approach for sending cholecystectomy specimens for histopathology results in missing discrete pathologies such as premalignant benign lesions such as porcelain gallbladder, carcinoma-in-situ, and early carcinomas. To avoid such blunders therefore, every cholecystectomy specimen should be routinely examined histologically. Unfortunately, the practice of discarding gallbladder specimen is standard in most tertiary care hospitals of Pakistan including the primary investigators’ own institution. This study was conducted to assess the feasibility or otherwise of performing histopathology in every specimen of gallbladder.
Methods
This cohort study included 220 patients with gallstones for cholecystectomy. All cases with known secondaries from gallbladder, local invasion from other viscera, traumatic rupture of gallbladder, gross malignancy of gallbladder found during surgery was excluded from the study. Laparoscopic cholecystectomy was performed in majority of cases except in those cases where anatomical distortion and dense adhesions prevented laparoscopy. All gallbladder specimens were sent for histopathology, irrespective of their gross appearance.
Results
Over a period of two years, 220 patients with symptomatic gallstones were admitted for cholecystectomy. Most of the patients were females (88%). Ninety two per cent patients presented with upper abdominal pain of varying duration. All specimens were sent for histopathology. Two hundred and three of the specimens showed evidence chronic cholecystitis, 7 acute cholecystitis with mucocele, 3 acute cholecystitis with empyema and one chronic cholecystitis associated with poly. Six gallbladders (2.8%) showed adenocarcinoma of varying differentiation along with cholelithiasis.
Conclusion
The histopathological spectrum of gallbladder is extremely variable. Incidental diagnosis of carcinoma gall bladder is not rare; if the protocol of routine histopathology of all gallbladder specimens is not followed, subclinical malignancies would fail to be identified with disastrous results. We strongly recommend routine histopathology of all cholecystectomy specimens.

16.  Biliary tract cancers in Cote-d'Or (France): incidence and natural history. 
The registry of digestive tract tumours established for the department of Cote-d'Or (France) was used to study the epidemiological characteristics and the natural history of biliary tract cancers. Age standardised incidence rates for gallbladder cancers were 2.7/100,000 for women and 0.9/100,000 for men. The corresponding rates for extrahepatic bile duct cancers were 0.5/100,000 and 1.7/100,000, and for ampulla of Vater cancer 0.3/100,000 and 0.3/100,000. The three cancers differ in their descriptive epidemiology and should be considered separately in epidemiological analytical investigations. The incidence of each of the three diseases increased with age, and cancers of known histological type were mainly adenocarcinomas. Some gallbladder cancers were undifferentiated or squamous cell carcinomas. There was no significant variation in incidence for gallbladder cancer and extrahepatic bile duct cancer over the eight years of the study. The association with gallstones was frequent in gallbladder cancer: 70.5% compared to 13.0% in other biliary tract cancers (less than 0.001). Although the association of gallbladder cancer with gallstones is frequent, few patients with cholelithiasis experience development of a gallbladder cancer. It is necessary to identify among patients with gallstones a subgroup at high risk of gallbladder cancer in whom prophylactic surgery might be justified. Biliary tract cancers are seldom diagnosed early: lymph nodes or visceral metastases were present in 77% of gallbladder cancers, in 83% of extrahepatic bile duct cancers, and in 55% of ampulla of Vater cancers at the time of diagnosis. The corresponding resectability rates were 46.1%, 11.9%, and 38.9%. The five-year overall survival rates were 2.9% for gallbladder cancer, 0% for extrahepatic bile duct cancer, and 18.3% for ampulla of Vater cancer. The corresponding five-year survival rates after surgery for cure were 10.3%, 0%, and 35.7%. Biliary tract cancer still represent a great therapeutic challenge.

17.  Surgical management of gallbladder cancer 
The Indian Journal of Surgery  2010;71(6):363-367.
Gallbladder cancer is a very common malignancy in the northern part of India. Surgery is the only potentially curative modality of treatment for this disease. Radical cholecystectomy is the optimal surgical standard for resectable gallbladder cancer. This includes cholecystectomy, liver resection (wedge, segments 4b and 5, or extended right hepatectomy), and regional lymphadenectomy along the hepatoduodenal ligament, behind the duodenum and pancreatic head, common hepatic artery and celiac axis. Controversies regarding extent of liver resection, lymphadenectomy and role of multiorgan resection have been discussed. Incidental gallbladder cancer is often detected on histopathologic examination of the simple cholecystectomy specimen removed for a presumed gallstone disease. Revision surgery should be performed for incidental cancers that invade muscularis propria or beyond (T1b or more). Advanced gallbladder cancer should be treated non-operatively with a palliative intent. Obstructive jaundice in the setting of an advanced gallbladder cancer can be palliated with biliary stenting by endoscopic or transhepatic means. Occasionally, a surgical biliary bypass may be indicated to relieve intractable pruritus in a jaundiced patient with gallbladder cancer. There is no role of a planned R2 resection of advanced gallbladder cancer for the purpose of cytoreduction. Further improvement in the management of gallbladder cancer will need integration of systemic chemotherapy with radical surgery.

18.  A severe case of hemobilia and biliary fistula following an open urgent cholecystectomy 
Background
Cholecystectomy has been the treatment of choice for symptomatic gallstones, but remains the greatest source of post-operative biliary injuries. Laparoscopic approach has been recently preferred because of short hospitalisation and low morbidity but has an higher incidence of biliary leakages and bile duct injuries than open one due to a technical error or misinterpretation of the anatomy. Even open cholecystectomy presents a small number of complications especially if it was performed in urgency. Hemobilia is one of the most common cause of upper gastrointestinal bleeding from the biliary ducts into the gastrointestinal tract due to trauma, advent of invasive procedures such as percutaneous liver biopsy, transhepatic cholangiography, and biliary drainage.
Methods
We report here a case of massive hemobilia in a 60-year-old man who underwent an urgent open cholecystectomy and a subsequent placement of a transhepatic biliary drainage.
Conclusion
The management of these complications enclose endoscopic, percutaneous and surgical therapies. After a diagnosis of biliary fistula, it's most important to assess the adequacy of bile drainage to determine a controlled fistula and to avoid bile collection and peritonitis. Transarterial embolization is the first line of intervention to stop hemobilia while surgical intervention should be considered if embolization fails or is contraindicated.

19.  Diagnosis of incidental gallbladder cancer after laparoscopic cholecystectomy: our experience 
BMC Surgery  2013;13(Suppl 2):S20.
Background
Gallbladder carcinoma is a rare high malignancy neoplasm. The incidence of intra or post-operative incidental gallbladder carcinoma diagnosis is estimated between 0,2 and 2,8%. Primary aim of our study is to evaluate incidental gallbladder carcinoma's incidence in our experience.
Methods
We retrospectively reviewed our Surgery Division's experience about the totality of laparoscopic cholecystectomies with post-operative histological evidence of incidental gallbladder cancer. We evaluated patients' characteristics, surgical related variables, histological response, surgivcal radicalization characteristics and surgical outcome.
Results
In the considered sample we observed 7 accidental gallbladder adenocarcinomas in post-operative histological examination. Pathological results were:1 pT1b N0 (G1), 2 pT2 N0 (G2), 2 pT2 N1 (G3b), 2 pT3 N1 (G3b) (Table 1). In 5 cases we performed neoplasm radicalization surgery with standard procedure revision. Two patients died before radicalization. Median global survival was 34 months.
Conclusion
With the increase of laparoscopic cholecystectomies both elective and urgent performed in our centre we observed also an increase of incidentally diagnosed gallbladder neoplasms. Early diagnosis, meticulous peri-operative study and accurate surgical strategy are essential factors to obtain good results in incidental gallbladder cancer.

20.  Laparoscopic Cholecystectomy and Incidental Carcinoma of the Extrahepatic Biliary Tree 
Background and Objectives:
Gallbladder carcinoma is found in 0.2 % to 5% of patients undergoing cholecystectomy, and gallstones are found in 70% to 98% of patients with gallbladder carcinoma. Early diagnosis of carcinoma is difficult because of the absence of specific symptoms and the frequent association with chronic cholecystitis and gallstones. At present, laparoscopic cholecystectomy is the gold standard for the surgical treatment of symptomatic cholelithiasis and other benign gallbladder diseases. The aims of this study were to evaluate retrospectively the incidence of occasional and occult gallbladder carcinomas to ascertain the effect of laparoscopy on diagnosis and treatment of unexpected extrahepatic biliary tree carcinomas and to assess possible guidelines that can be taken into consideration when the problem is encountered.
Methods:
Clinical records of 3900 patients undergoing laparoscopic cholecystectomy were reviewed. Patients with occasional (intraoperative = Group A) or occult (postoperative = Group B) diagnosis of gallbladder or common bile duct carcinoma entered the study group. Follow-up data were obtained in June 2000.
Results:
A total of 14 patients (0.35%), 3 men and 11 women, mean age 60.8 years (range 37 to 73) with extra-hepatic biliary tree carcinoma were found. Occasional carcinomas occurred in 8 patients, occult carcinomas in 6. No deaths occurred in either group. The overall survival at mean follow-up of 30.5 months is 50%. Five patients are disease free, and 2 are alive with evidence of recurrence.
Discussion:
In 2 large series of unselected consecutive laparoscopic cholecystectomy, only 14 unsuspected malignant tumors of the extrahepatic biliary tree were found (0.35%). The limits of the preoperative workup and the difficult diagnosis of biliary tract carcinoma during laparoscopic cholecystectomy, has led to the present retrospective study and several significant recommendations.

21.  Incidental Gall Bladder Carcinoma in Laparoscopic Cholecystectomy: A Report of 6 Cases and a Review of the Literature 
Background: Gall bladder carcinoma accounts for 98% of all the gall bladder malignancies and it is the sixth most common malignancy of the gastrointestinal tract worldwide. The incidence of incidental gall bladder carcinoma which is diagnosed during or after a laparoscopic cholecystectomy is reported to be around 0.19-3.3% in the literature.
Aim: This study was aimed at detecting the incidence of gall bladder carcinomas which were diagnosed incidentally during or after laparoscopic cholecystectomies which were done for gall stone disease and cholecystitis.
Materials and Methods: We analyzed the medical records of patients with symptomatic gallstone disease and acute or chronic cholecystitis, who underwent laparoscopic cholecystectomies at the Hakeem Abdul Hameed Centenary Hospital during the period from January 2007 to June 2012.
Results: A total of 622 laparoscopic cholecystectomies were performed at our institute during the study period of five and a half years. In 6 (0.96%) cases, incidental carcinomas of the gallbladder were discovered.
Conclusion: A laparoscopic cholecystectomy which is performed for benign gall bladder disease rarely results in a diagnosis of unexpected gallbladder cancer. The microscopic examination of the specimens, with special attention to the depth of invasion, range of the mucosal spread and the lymphovascular involvement, is critical in diagnosing the incidental malignancies as well as for the subsequent management of the cases.

22.  Total Laparoscopic Roux-en-Y Cholangiojejunostomy for the Treatment of Biliary Disease 
Total laparoscopic Roux-en-Y cholangiojejunostomy may be a first choice for patients with biliary disease that requires biliary-jejunal anastomosis.
Background and Objectives:
Roux-en-Y cholangiojejunostomy (RCJS) has been widely used in biliary bypass surgeries, but in most reported literature, an assisted mini-incision was needed, and studies reporting total laparoscopic Roux-en-Y cholangiojejunostomy (TLRCJS) are rare. The goal of this study was to investigate how to treat hepatic portal bile duct diseases and perform jejunojejunostomy and cholangiojejunostomy totally laparoscopically. We evaluated the feasibility of TLRCJS in treating biliary tract diseases.
Methods:
TLRCJS were performed in 103 patients from January 2000 to August 2011. There were 28 cases of recurrent choledocholithiasis combined with stricture of the common bile duct (CBD) after several stone extractions, 3 patients with iatrogenic bile duct injury, 24 patients with choledochal cyst, 36 patients with hepatic portal cholangiocarcinoma, and 12 patients with cancer of the pancreatic head and periampullary cancer. All surgeries were performed through 5 trocars. First, laparoscopic surgery on the CBD was performed according to the original disease. The CBD was opened and stones were extracted in choledocholithiasis patients. In iatrogenic injury patients, strictured CBD was resected and repaired. Dilated CBD or choledochal cyst with tumor was transected. In patients with malignant jaundice, the CBD was opened longitudinally. At the same time, the bile duct was prepared for cholangiojejunostomy. Second, the positions of the laparoscope and surgeons were altered. The jejunal mesentery and jejunum were transected, and side-to-side jejunojejunostomy (JJS) was performed. The laparoscope and surgeon positions were exchanged again; the Roux-en-Y biliary limb was lifted close to the residual bile duct; and side-to-side or end-to-side choledochojejunostomy (CJS) was performed. Finally, an abdominal drainage tube was placed.
Results:
All the surgeries were performed successfully. The diameter of the residual bile duct ranged from 0.4 to 3.2 cm (average, 0.9 cm). Three patients had postoperative bile leakage and were treated from 1 week to approximately 1 month with abdominal drainage. Postoperative intraperitoneal hemorrhage and stress ulcer of the stomach occurred in 2 patients with biliary tract injury combined with obstructive jaundice. One with intraperitoneal hemorrhage was cured by another laparoscopic surgery. The other patient was cured after 2 days of abdominal drainage, antacids, and hemostatic drug therapy. The follow-up duration of 95 patients was 4 to 93 months (average, 48.3 months). The follow-up rate was 92.2% (95/103). Patients with cancer died of metastasis or cachexia during 14-month follow-up with no postoperative complication. Reflux cholangitis occurred in 3 patients 2, 3, and 5 years after the operation, respectively. No anastomotic stricture or other complication was found in other patients during the follow-up.
Conclusions:
TLRCJS is the best and first choice for patients with biliary tract diseases that need biliary-jejunal anastomosis. But it is essential that the surgeon has proficiency in laparoscopic surgeries.

23.  Role and outcome of conventional surgery in the treatment of pyogenic liver abscess in the modern era of minimally invasive therapy 
AIM: To evaluate the role and outcome of conventional surgery in the treatment of pyogenic liver abscess in the modern era of minimally invasive therapy.
METHODS: The medical records of thirteen patients with pyogenic liver abscess who underwent surgical treatment between January 1995 and December 2002 were retrospectively reviewed to determine the clinical presentation, indication and nature of surgery, and outcome of surgery.
RESULTS: The patients were predominantly women (10/13) with a mean age of 65 ± 17 years. Their main presenting symptoms were abdominal pain (100%) and fever (77%). The aetiologies included biliary (n = 6), cryptogenic (n = 3), portal (n = 2), and trauma (n = 2). Seven patients underwent percutaneous drainage as the initial treatment. Of these, three patients developed peritonitis secondary to peritoneal spillage. Another four patients failed to respond because of multiloculation. Salvage surgery was required in these patients. Six patients proceeded to straight laparotomy: two had marked sepsis and multiloculated abscess that precluded percutaneous drainage, and four presented with peritonitis of uncertain pathology. Surgical procedures included deroofment and drainage (n = 9), liver resection (n = 3), peritoneal lavage (n = 2), cholecystectomy (n = 4), and exploration of common bile duct (n = 2). One patient required reoperation because of bleeding. Three patients required further percutaneous drainage after surgery. The overall mortality was 46%. Four patients died of multiorgan failure and two patients died of pulmonary embolism.
CONCLUSION: Surgical treatment of pyogenic liver abscess is occasionally needed when percutaneous drainage has failed due to various reasons. Mortality rate in this group of patients has remained high.

24.  Risk factors for biliary tract and ampullary carcinomas and prophylactic surgery for these factors 
Curative resection is the only treatment for biliary tract cancer that achieves long-term survival. However, patients with advanced biliary tract cancer have only a limited prognosis even after radical surgical resection. Thus, to improve the longterm results, the early detection of biliary tract cancer and subsequent cure seem to be essential. The purpose of this study was to review the literature concerning the risk factors for cancerous and precancerous lesions of the biliary tract, and prophylactic surgery for these factors. It has been reported that pancreaticobiliary maljunction (PBM) with bile duct dilatation is a risk factor for gallbladder cancer and bile duct cancer, while PBM without bile duct dilatation is a risk factor for gallbladder cancer. Thus, in the former group, a prophylactic excision of the common bile duct and gallbladder should be recommended, while in the later group, a prophylactic cholecystectomy without bile duct resection may be the appropriate surgical procedure. It has also been reported that primary sclerosing cholangitis (PSC) is a risk factor for cholangiocarcinoma. Patients with PSC often develop advanced cholangiocarcinoma with a poor prognosis. In patients with PSC, therefore, strict follow-up should be recommended. Adenoma and dysplasia have been regarded as precancerous lesions of gallbladder cancer. A polypoid lesion of the gallbladder that is sessile, has a diameter greater than 10 mm, and /or grows rapidly, is highly likely to be cancerous and should be resected. Although gallstones seem to be closely associated with gallbladder cancer, there is no evidence of a direct causal relationship between gallstones and gallbladder cancer. Thus, a cholecystectomy is not advised for asymptomatic cholecystolithiasis. Controversy remains as to whether adenomyomatosis of the gallbladder and porcelain gallbladder are associated with gallbladder cancer. With respect to ampullary carcinoma, adenoma of the ampulla is considered to be a precancerous lesion. This article discusses the risk factors for cancerous and precancerous lesions of the biliary tract and prophylactic treatment for these factors.

25.  Incidentally Detected Gallbladder Cancer- The Controversies and Algorithmic Approach to Management 
The Indian Journal of Surgery  2012;74(3):248-254.
Incidentally discovered gallbladder cancer (IGBC) is defined as the gallbladder cancer (GBC) diagnosed during or after the cholecystectomy done for unsuspected benign gallbladder disease. Laparoscopic cholecystectomy (LC) is the most common procedure performed for benign gallbladder disease worldwide. Majority of GBC patients have associated gallstones. With the advent of ultrasonography more patients are being diagnosed with gallstones and are being subjected to cholecytectomy. IGBC is found in 0.2–2.9 % of all cholecytectomies done for gallstone disease. It represents 27–41 % of all GBC. Patients with IGBC having Tis and T1a stage, with negative cystic duct margin can be treated by simple cholecystectomy alone. Patients with stage T1b and beyond should undergo restaging, and should be treated with radical re - resection (R0). Residual disease is found in 40–76 % patients on re-exploration. The survival rates of patients undergoing re resection for IGBC is similar to those undergoing primary radical surgery. LC is contraindicated in patients with GBC. Patients presenting post LC should undergo radical re- resection and additional port site excision, as they have a high incidence of port site metastasis. At cholecystectomy for benign gallbladder disease all gallbladder specimens should be opened before closing abdomen and if available all suspicious specimens should be sent for immediate frozen section. All gallbladder specimens should be subjected to histopathology examination to avoid missing GBC. The surgeon should have a high index of suspicion for GBC if encountering difficult cholecystectomy for a benign disease, and in patients with atypical clinical and ultrasound findings in high incidence areas.
