1.  Management of ERCP-related small bowel perforations: the pivotal role of physical investigation 
Canadian Journal of Surgery  2012;55(2):99-104.
Management of endoscopic retrograde cholangiopancreatography (ERCP)–associated duodenal perforation remains controversial. Some recommend surgery, while others recommend conservative treatment.
A retrospective chart review was conducted to identify patients treated at our institution for ERCP-related duodenal perforations. Study variables included indication for ERCP, clinical presentation, diagnostic procedures, time to diagnosis and treatment, location of injury, management, length of stay in hospital and survival.
Between January 2000 and October 2009, 12 232 ERCP procedures were performed at our centre, and perforation occured in 11 patients (0.08%; 5 men, 6 women, mean age 71 yr). Six of the perforations were discovered during ERCP; 5 required radiologic imaging for diagnosis. Three perforations were diagnosed incidentally by follow-up ERCP. In 1 patient, perforation occurred 3 years after the procedure owing to a dislocated stent. Four of 11 perforations were stent-related; in 2 patients ERCP was performed in a nonanatomic situation (Billroth II gastroenterostomy). Free peritoneal perforation occurred in 4 patients; 1 was successfully managed conservatively. Four patients (36%) were treated surgically and none died. Five patients were managed conservatively with a successful outcome, and 2 patients died after conservative treatment (18%). Operative treatment included hepaticojejunostomy and duodenostomy (1 patient), suture of the perforation with T-drain (1 patient) and suture only (2 patients). The mean length of stay in hospital for all patients was 20 days.
Post-ERCP duodenal perforations are associated with significant morbidity and mortality. Immediate surgical evaluation and close monitoring is needed. Management should be individually tailored based on clinical findings only.

2.  Management of endoscopic retrograde cholangiopancreatography-related perforations 
The purpose of this study is to analyze the treatment strategies of patients with endoscopic retrograde cholangiopancreatography (ERCP)-related perforations. This is a retrospective study.
We experienced 13 perforations associated with ERCP. We reviewed the medical recordsand classified ERCP-related perforations according to mechanism of injury in terms of perforating device. Injury by endoscopic tip or insertion tube was classified as type I, injury by cannulation catheter or sphincterotomy knife as type II, and injury by guidewire as type III.
Of four type I injuries, one case was managed by conservative management after primary closure with a hemoclip during ERCP. The other three patients underwent surgical treatments such as primary closure orpancreatico-duodenectomy. Of five type II injuries, two patients underwent conservative management and the other three cases were managed by surgical treatment such as duodenojejunostomy, duodenal diverticulization and pancreatico-duodenectomy. Of four type III injuries, three patients were managed conservatively and the remaining patient was managed by T-tube choledochostomy.
Type I injuries require immediate surgical management after EPCP or immediate endoscopic closure during ERCP whenever possible. Type II injuries require surgical or conservative treatment according to intra- and retro-peritoneal dirty fluid collection findings following radiologic evaluation. Type III injuries almost always improve after conservative treatment with endoscopic nasobilliary drainage.

3.  Early Management Experience of Perforation after ERCP 
Background and Aim. Perforation after endoscopic retrograde cholangiopancreatography (ERCP) is a rare complication, but it is associated with significant mortality. This study evaluated the early management experience of these perforations. Patients and Methods. Between November 2003 and December 2011, a total of 8504 ERCPs were performed at our regional endoscopy center. Sixteen perforations (0.45%) were identified and retrospectively reviewed. Results. Nine of these 16 patients with perforations were periampullary, 3 duodenal, 1 gastric fundus, and 3 patients had a perforation of an afferent limb of a Billroth II anastomosis. All patients with perforations were recognized during ERCP by X-ray and managed immediately. One patient with duodenal perforation and three patients with afferent limb perforation received surgery, others received medical conservative treatment which included suturing lesion, endoscopic nasobiliary drainage (ENBD), endoscopic retrograde pancreatic duct drainage (ERPD), gastrointestinal decompression, fasting, broad-spectrum antibiotics, and so on. All patients with perforation recovered successfully. Conclusions. We found that: (1) the diagnosis of perforation during ERCP may be easy, but you must pay attention to it. (2) Most retroperitoneal perforations can recover with only medical conservative treatment in early phase. (3) Most peritoneal perforations need surgery unless you can close the lesion up under endoscopy in early phase.

4.  Endoscopic duodenal perforation: surgical strategies in a regional centre 
Duodenal perforation is an uncommon complication of endoscopic retrograde cholangio-pancreatography (ERCP) and a rare complication of upper gastrointestinal endoscopy. Most are minor perforations that settle with conservative management. A few perforations however result in life-threatening retroperitoneal necrosis and require surgical intervention. There is a relative paucity of references specifically describing the surgical interventions required for this eventuality.
Five cases of iatrogenic duodenal perforation were ascertained between 2002 and 2007 at Cairns Base Hospital. Clinical features were analyzed and compared, with reference to a review of ERCP at that institution for the years 2005/2006.
One patient recovered with conservative management. Of the other four, one died after initial laparotomy. The other three survived, undergoing multiple procedures and long inpatient stays.
Iatrogenic duodenal perforation with retroperitoneal necrosis is an uncommon complication of endoscopy, but when it does occur it is potentially life-threatening. Early recognition may lead to a better outcome through earlier intervention, although a protracted course with multiple procedures should be anticipated. A number of surgical techniques may need to be employed according to the individual circumstances of the case.

5.  Endoscopic Treatments of Endoscopic Retrograde Cholangiopancreatography-Related Duodenal Perforations 
Clinical Endoscopy  2013;46(5):522-528.
Iatrogenic duodenal perforation associated with endoscopic retrograde cholangiopancreatography (ERCP) is a very uncommon complication that is often lethal. Perforations during ERCP are caused by endoscopic sphincterotomy, placement of biliary or duodenal stents, guidewire-related causes, and endoscopy itself. In particular, perforation of the medial or lateral duodenal wall usually requires prompt diagnosis and surgical management. Perforation can follow various clinical courses, and management depends on the cause of the perforation. Cases resulting from sphincterotomy or guidewire-induced perforation can be managed by conservative treatment and biliary diversion. The current standard treatment for perforation of the duodenal free wall is early surgical repair. However, several reports of primary endoscopic closure techniques using endoclip, endoloop, or newly developed endoscopic devices have recently been described, even for use in direct perforation of the duodenal wall.

6.  Primary endoscopic approximation suture under cap-assisted endoscopy of an ERCP-induced duodenal perforation 
Duodenal perforation during endoscopic retrograde cholangiopancreatography (ERCP) is a rare complication, but it has a relatively high mortality risk. Early diagnosis and prompt management are key factors for the successful treatment of ERCP-related perforation. The management of perforation can initially be conservative in cases resulting from sphincterotomy or guide wire trauma. However, the current standard treatment for duodenal free wall perforation is surgical repair. Recently, several case reports of endoscopic closure techniques using endoclips, endoloops, or fully covered metal stents have been described. We describe four cases of iatrogenic duodenal bulb or lateral wall perforation caused by the scope tip that occurred during ERCP in tertiary referral centers. All the cases were simply managed by endoclips under transparent cap-assisted endoscopy. Based on the available evidence and our experience, endoscopic closure was a safe and feasible method even for duodenoscope-induced perforations. Our results suggest that endoscopists may be more willing to use this treatment.

7.  Unusual Complications Related to Endoscopic Retrograde Cholangiopancreatography and Its Endoscopic Treatment 
Clinical Endoscopy  2013;46(3):251-259.
Endoscopic retrograde cholangiopancreatography (ERCP)-induced complications, once occurred, can lead to significant morbidity. Commonly 5% to 10% of patients experience procedure related complications such as post-ERCP pancreatitis, biliary hemorrhage, and cholangitis, in descending order. However, complications such as perforation, pneumothorax, air embolism, splenic injury, and basket impaction are rare but are associated with high mortality if occurred. Such unexpected unusual complications might extend the length of hospitalization, require urgent surgical intervention, and put the patient in miserable condition leading to permanent disability or mortality. Although these ERCP-induced complications can be minimized by a skilled operator using advanced techniques and devices, the occurrence of unusual complications are hard to expect and induce very difficult management condition. In this review, we will focus on the uncommon complications related to ERCP. This review is also aimed at suggesting optimal endoscopic treatment strategies for several complications based on our institutional experiences.

8.  Closure of a persistent sphincterotomy-related duodenal perforation by placement of a covered self-expandable metallic biliary stent 
Retroperitoneal duodenal perforation as a result of endoscopic biliary sphincterotomy is a rare complication, but it is associated with a relatively high mortality risk, if left untreated. Recently, several endoscopic techniques have been described to close a variety of perforations. In this case report, we describe the closure of a persistent sphincterotomy-related duodenal perforation by using a covered self-expandable metallic biliary (CEMB) stent. A 61-year-old Greek woman underwent an endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy for suspected choledocholithiasis, and a retroperitoneal duodenal perforation (sphincterotomy-related) occurred. Despite initial conservative management, the patient underwent a laparotomy and drainage of the retroperitoneal space. After that, a high volume duodenal fistula developed. Six weeks after the initial ERCP, the patient underwent a repeat endoscopy and placement of a CEMB stent with an indwelling nasobiliary drain. The fistula healed completely and the stent was removed two weeks later. We suggest the transient use of CEMB stents for the closure of sphincterotomy-related duodenal perforations. They can be placed either during the initial ERCP or even later if there is radiographic or clinical evidence that the leakage persists.

9.  A Case of Ampullary Perforation Treated with a Temporally Covered Metal Stent 
Clinical Endoscopy  2012;45(2):177-180.
Endoscopic retrograde cholangiopancreatography (ERCP)-related perforation is classified into three or four types based on anatomical location and the mechanism of injury. Although ampullary injury, among them, may be managed nonsurgically, surgical management is required in cases of perforation with retroperitoneal fluid collection and severe condition. Here, a patient with ERCP-related severe ampullary perforation with retroperitoneal fluid collection that was treated nonsurgically with a covered stent is presented.

10.  Laparoscopic Management of a Retroperitoneal Duodenal Perforation Following ERCP for Periampullary Cancer 
Endoscopic retrograde cholangiopancreatography (ERCP) is a fairly common procedure being performed in several centers worldwide. Although it is proven to be efficient and relatively safe, complications do occur (1.8%). We present a patient with ERCP-induced retroperitoneal perforation of the duodenum treated laparoscopically at our institution.
Case Report:
The patient is a 60-year-old female who underwent ERCP for obstructive jaundice due to periampullary carcinoma, during which the perforation occurred. Laparoscopy was performed 5 hours later and the perforation sutured primarily.
The operating time was 125 minutes. On the fourth postoperative day, the patient developed a retroperitoneal collection, confirmed by computed tomographic scan. Re-look laparoscopy was performed and the fluid drained. She recovered completely and was discharged on the eighth postoperative day.
Duodenal perforation following ERCP is rare, with an incidence of 1.8%. Both surgical and non-surgical management have been reported, each with its specific indications. Our patient needed surgery, because the perforation was large and a retroperitoneal collection was present. Laparotomy is the preferred approach, though now laparoscopy is a viable and effective alternative, because it provides the benefits of minimal access, such as reduced pain and early ambulation.

11.  Therapeutic Endoscopy of the Hepatobiliary and Pancreatic System: A Vietnamese Experience 
Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) was initially utilized at Binh Dan Hospital, Viet Nam, in August 1993. From August 1993 through March 1997, 318 ERCP procedures were performed on 271 patients. It was not possible to obtain cholangiography in 32 cases of the 318 procedures of ERCP, for a success rate of diagnostic ERCP approaching 89%.
Materials and Methods:
Cases treated by ERCP included: 14 cases of Ascaris lumbricoides in the common bile duct (CBD).
69 cases of bile duct stones.
12 cases managed by nasobiliary catheter drainage.
3 cases treated by bile duct stent.
Sphincterotomy was attempted on 108 cases.
Complications included: 5 cases of acute pancreatitis.7 cases of purulent cholangitis, which resulted in 1 death.2 cases of retroperitoneal duodenal perforation.9 cases of postsphincterotomy bleeding.
We conclude that ERCP is a useful therapeutic modality for bile duct stones and parasitic worms in the bile ducts.

12.  Surgical intervention of severe post-ERCP-pancreatitis accompanied with duodenum perforation*  
Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure widely used to diagnose and treat conditions of biliary or pancreatic ductal system. The post-ERCP severe acute pancreatitis (SAP) accompanied with duodenum perforation is rare but serious, remaining a challenge in clinic. In this study we report two such cases. Two Chinese women were treated for clinical suspicion of bile duct obstruction and underwent ERCP after admission. Both developed duodenum perforation and SAP after ERCP, and were managed in the intensive care unit (ICU) and required an organ-failure support. The surgical intervention of the peri-pancreatic debridement with lumber-abdominal compound incisions and postoperative washing and drainage was performed, and the two patients recovered well. The therapeutic effect of the peri-pancreatic debridement with lumber-abdominal compound incisions combined with postoperative washing and drainage in the patients of severe post-ERCP-pancreatitis (PEP) and duodenum perforation is satisfactory.

13.  Successful Nonsurgical Treatment of Pneumomediastinum, Pneumothorax, Pneumoperitoneum, Pneumoretroperitoneum, and Subcutaneous Emphysema following ERCP 
Complications related to endoscopic retrograde cholangiopancreatography (ERCP) include pancreatitis, hemorrhage, cholangitis, and perforation. ERCP-related perforation is uncommon, but mortality rates are high. Diagnosis requires a high clinical suspicion for early detection to allow optimal management of the perforation and a better prognosis. Treatment depends on the location and mechanism and increasingly involves nonoperative management. We report a case of successful nonsurgical treatment of a patient with extensive air involving the peritoneum, retroperitoneum, thorax, mediastinum, and subcutaneous tissues following an ERCP perforation.

14.  Massive Subcutaneus Emphysema following Endoscopic Retrograde Cholangiopancreatography with Sphincterotomy 
Case Reports in Gastroenterology  2010;4(3):399-403.
Although endoscopic retrograde cholangiopancreatography (ERCP) is an effective procedure for the diagnosis and treatment of the pancreatic and extrahepatic biliary tract diseases, it is still related with several complications. A female patient who underwent an ERCP with sphincterotomy developed massive subcutaneous emphysema along with pneumomediastinum and pneumoperitoneum. Although mild respiratory distress occurred, based on the absence of intaabdominal leakage of gastrografin, the patient was managed conservatively. In conclusion, the retroperitoneal air collection related to ERCP is well recognized even in the absence of obvious perforation and may spread to adjacent areas, causing serious complications.

15.  Liver Parenchyma Perforation following Endoscopic Retrograde Cholangiopancreatography 
Case Reports in Gastroenterology  2011;5(2):487-491.
Although endoscopic retrograde cholangiopancreatography (ERCP) is an effective modality for the diagnosis and treatment of biliary and pancreatic diseases, it is still related with several severe complications. We report on the case of a female patient who developed liver parenchyma perforation following ERCP. She underwent ERCP with sphincterotomy and extraction of a common bile duct stone. Shortly after ERCP, abdominal distension was identified. Abdominal computed tomography revealed intraabdominal air leakage and leakage of contrast dye penetrating the liver parenchyma into the space around the spleen. Since periampullary perforation related to sphincterotomy could not be denied, she was referred for immediate surgery. Obvious perforation could not be found at surgery. Cholecystectomy, insertion of a T tube into the common bile duct, placement of a duodenostomy tube and drainage of the retroperitoneum were performed. She did well postoperatively and was discharged home on postoperative day 28. In conclusion, as it is well recognized that perforation is one of the most serious complication related to ERCP, liver parenchyma perforation should be suspected as a cause.

16.  Clinical outcomes and risk factors for perforation in gastric endoscopic submucosal dissection: A prospective pilot study 
AIM: To evaluate clinical outcomes and risk factors for endoscopic perforation during endoscopic submucosal dissection (ESD) in a prospective study.
METHODS: We investigated the clinical outcomes and risk factors for the development of perforation in 98 consecutive gastric neoplasms undergoing ESD regarding. Demographic and clinical parameters including patient-, tumor-, and treatment-related factors, clinical parameters, and duration of hospital stay were analyzed for risk factors for perforation. In subgroup analysis, we also compared the clinical outcomes between perforation and “silent” free air without endoscopically visible perforation detected only by computed tomography.
RESULTS: Perforation was identified in 8.2% of patients. All patients were managed conservatively by the administration of antibiotics. The mean procedure time was significantly longer in patients with endoscopic perforation than in those without. According to the receiver-operating characteristic analysis, the resulting cutoff value of the procedure time for perforation was 115 min (87.5% sensitivity, 56.7% specificity). Prolonged procedure time (≥ 115 min) was associated with an increased risk of perforation (odds ratio 9.15; 95%CI: 1.08-77.54; P = 0.04). Following ESD, body temperature and C-reactive protein level were significantly higher in patients with perforation than in those without (P = 0.02), whereas there was no difference between these patient groups on the starting day of oral intake or of hospitalization. In subgroup analysis, the post-ESD clinical course was not different between endoscopic perforation and silent free air.
CONCLUSION: Only prolonged procedure time (≥ 115 min) was significantly associated with perforation. The clinical outcomes of perforation are favorable and are comparable to those of patients with or without silent free air.

17.  Iatrogenic Duodenal Perforation Treated with Endoscopic Placement of Metallic Clips: A Case Report 
Case Reports in Medicine  2012;2012:609750.
Perforation is one of the major complications encountered during endoscopic procedures. The standard of care for these complications is either surgical intervention or nonoperative medical approach with antibiotics and bowel rest with or without parenteral alimentation. Metallic clips, initially developed to secure hemostasis in bleeding, have been successfully used to close perforations in the gastrointestinal tract (GI) including the duodenum. This avoids perioperative morbidities associated with surgical intervention while limiting the leakage of intestinal contents and peritoneal contamination that is possible with medical management. We present a case of a patient with a lateral duodenal perforation during an endoscopic retrograde cholangiopancreatography (ERCP) which was successfully treated with immediate placement of metallic endoclips.

18.  Risk factors for therapeutic ERCP-related complications: an analysis of 2,715 cases performed by a single endoscopist 
Annals of Gastroenterology  2014;27(1):65-72.
Endoscopic retrograde cholangiopancreatography (ERCP) is now the exclusive endoscopic therapeutic modality for biliary as well as pancreatic diseases. The aim of the present study was to investigate patient- and procedure-related risk factors for post-ERCP complications in a large-scale study of procedures performed by a single experienced endoscopist.
This is a retrospective cohort study which included a total of 2,715 therapeutic ERCPs enrolled in the final analysis. Potential important patient- and procedure-related risk factors for overall post-ERCP complications, pancreatitis and post-endoscopic sphincterotomy (ES) bleeding were investigated by univariate and multivariate analyses.
Following the first therapeutic ERCP, 327 patients suffered complications; pancreatitis was observed in 132 (4.9%) patients, hemorrhage in 122 (4.5%) patients, cholangitis in 63 (2.3%) patients, perforation in 3 (0.11%) patients, and basket impaction in 7 (0.26%) patients. History of acute pancreatitis was more common in patients with post-ERCP complications (P<0.001). Female gender, young age (<40 years), periampullary diverticulum, suspected sphincter of Oddi dysfunction, metal stent placement, opacification of main pancreatic duct and suprapapillary fistulotomy were not found to be risk factors for overall post-ERCP complications and post-ERCP pancreatitis (PEP). Multivariate analysis showed a history of acute pancreatitis, difficult cannulation, needle-knife papillotomy, transpancreatic sphincterotomy, opacification of first and second class pancreatic ductules and acinarization as independent risk factors for overall complications and PEP, whereas antiplatelet and anticoagulation drug use were not found to be independent risk factors for post-ES bleeding.
The results of this study demonstrate that the endoscopist’s experience reduces patient- and procedure-related risk factors for post-ERCP complications.

19.  Successful Endoscopic Therapy of Traumatic Bile Leaks 
Traumatic bile leaks often result in high morbidity and prolonged hospital stay that requires multimodality management. Data on endoscopic management of traumatic bile leaks are scarce. Our study objective was to evaluate the efficacy of the endoscopic management of a traumatic bile leak. We performed a retrospective case review of patients who were referred for endoscopic retrograde cholangiopancreatography (ERCP) after traumatic bile duct injury secondary to blunt (motor vehicle accident) or penetrating (gunshot) trauma for management of bile leaks at our tertiary academic referral center. Fourteen patients underwent ERCP for the management of a traumatic bile leak over a 5-year period. The etiology included blunt trauma from motor vehicle accident in 8 patients, motorcycle accident in 3 patients and penetrating injury from a gunshot wound in 3 patients. Liver injuries were grade III in 1 patient, grade IV in 10 patients, and grade V in 3 patients. All patients were treated by biliary stent placement, and the outcome was successful in 14 of 14 cases (100%). The mean duration of follow-up was 85.6 days (range 54–175 days). There were no ERCP-related complications. In our case review, endoscopic management with endobiliary stent placement was found to be successful and resulted in resolution of the bile leak in all 14 patients. Based on our study results, ERCP should be considered as first-line therapy in the management of traumatic bile leaks.

20.  Prevention and Management of Post-Endoscopic Retrograde Cholangiopancreatography Complications 
Clinical Endoscopy  2012;45(3):305-312.
Endoscopic retrograde cholangiopancreatography (ERCP) is associated with a spectrum of complications such as pancreatitis, hemorrhage, perforation, and cardiopulmonary events. These complications can range from mild to severe resulting in extended hospitalization, requiring surgical intervention, and leading to permanent disability or even death. Complications of ERCP have been better understood in the past decade, with adoption of standardized consensus-based definitions of complications and introduction of new recommendations to minimize risks of ERCP. Adequate selection of patients undergoing ERCP, skilled operators using novel techniques and prompt identification and treatment are key to successful prevention and management.

21.  ERCP's Role in the Management of Acute Biliary-pancreatic Pathology in the Laparoscopic Era 
Laparoscopic cholecystectomy (LC) combined with endoscopic retrograde cholangiopancreatography (ERCP) has been widely used in the management of the acute biliopancreatic pathology. Nevertheless, controversy remains about the appropriate timing for retrograde cholangiopancreatography.
A retrospective study was undertaken on a consecutive series of 117 patients with acute biliary-pancreatic pathology, who underwent laparoscopic cholecystectomy between April 1995 and April 1999. Criteria for preoperative endoscopic retrograde cholangiopancreatography were defined, and the patients were divided into 3 groups based on the presence or absence of a preoperative retrograde cholangiopancreatography indication: (1) ERCP+LC group: patients with retrograde cholangiopancreatography indicated and performed (n = 30); (2) LC group: patients without retrograde cholangiopancreatography criteria treated only by LC (n = 47); (3) LC-ERCP group: patients with retrograde cholangiopancreatography criteria but not performed (n = 40).
The groups were similar in age, sex, ASA, and clinical diagnosis. No statistical differences occurred in operative times (73.8 min, 68 min, 67 min), major complications (3.3%, 4.25%, 12.5%), and mean postoperative stay (3.7 ± 4; 4.7 ± 2; 5.7 ± 2). Postoperative retrograde cholangiopancreatography had to be used, respectively, in 0%, 10.6%, and 7.5%. The best predictive criteria for common bile duct pathology were choledocholithiasis on an ultrasound scan and the presence of cholangitis. The other criteria tested had a low predictive value.
Preoperative endoscopic retrograde cholangiopancreatography followed by early laparoscopic chole-cystectomy can be performed safely in acute biliary-pancreatic pathology, avoiding 2-stage treatment of these patients and minimizing hospital stay and inconvenience to the patients. Nevertheless, this therapeutic/diagnostic tool must be used selectively.

22.  The clinical impact and cost implications of endoscopic ultrasound on the use of endoscopic retrograde cholangiopancreatography in a Canadian university hospital 
Endoscopic ultrasound (EUS) is a safe alternative to endoscopic retrograde cholangiopancreatography (ERCP) for diagnostic biliary imaging in choledocholithiasis. Evidence linking a decline in diagnostic ERCP with the introduction of EUS in clinical practice is limited.
To assess the clinical impact and cost implications of a new EUS program on diagnostic ERCP at a tertiary referral centre.
A retrospective review was performed of data collected during the first year of EUS at the University of Alberta Hospital (Edmonton, Alberta). Patients were referred for ERCP because of suspicion of choledocholithiasis based on clinical, biochemical and/or radiological parameters. If they were assessed to have an intermediate probability of choledocholithiasis, EUS was performed first. ERCP was performed if EUS suggested choledocholithiasis, whereas patients were clinically followed for six months if their EUS was normal. Cost data were assessed from a third-party payer perspective, and cost savings were expressed in terms of ERCP procedures avoided.
Over 12 months, 90 patients (63 female, mean age 58 years) underwent EUS for suspected biliary tract abnormalities. EUS suggested choledocholithiasis in 20 patients (22%), and this was confirmed by ERCP in 17 of the 20 patients. EUS was normal in 69 patients, and none underwent a subsequent ERCP during a six-month follow-up period. One patient had pancreatic cancer and did not undergo ERCP. The sensitivity and specificity of EUS for choledocholithiasis were 100% and 96%, respectively. A total of 440 ERCP procedures were performed over the same 12-month period, suggesting that EUS resulted in a 14% reduction in ERCP procedures (70 of 510). There were no complications of EUS. The cost of 90 EUS procedures was $42,840, compared with $108,854 for 70 ERCP procedures. The cost savings for the first year were $66,014.
EUS appears to be accurate, safe and cost effective in diagnostic biliary imaging for suspected choledocholithiasis. The impact of EUS is the avoidance of ERCP in selected cases, thereby preventing the risk of complications. Diagnostic ERCP should not be performed in centres and regions with physicians trained in EUS.

23.  Laparoscopic Common Bile Duct Exploration in Patients With Gallstones and Choledocholithiasis 
Failed ERCP appears to decrease the success rate of a laparoscopic approach for common bile duct exploration.
To compare the effectiveness of laparoscopic common bile duct exploration in patients with failed endoscopic retrograde cholangiopancreatography (ERCP).
This is a descriptive, comparative study. Patients with an indication of common bile duct exploration between February 2005 and October 2008 were included. We studied 2 groups: Group A: patients with failed ERCP who underwent LCBDE plus LC. Group B: patients with common bile duct stones managed with the 1-step approach (LCBDE + LC) with no prior ERCP.
Twenty-five patients were included. Group A: 9 patients, group B: 16 patients. Success rate, operative time, and hospital stay were as follows: group A 66% vs group B 87.5%; group A 187 minutes vs 106 minutes; group A 4.5 days vs 2.3 days; respectively.
Patients with failed ERCP should be considered as high-complex cases in which the laparoscopic procedure success rate decreases, and the conversion rate increases considerably.

24.  Endoscopic drainage for duodenal hematoma following endoscopic retrograde cholangiopancreatography: A case report 
Intramural duodenal hematoma (IDH) is a rare complication following endoscopic retrograde cholangiopancreatography (ERCP). Blunt damage caused by the endoscope or an accessory has been suggested as the main reason for IDH. Surgical treatment of isolated duodenal hematoma after blunt trauma is traditionally reserved for rare cases of perforation or persistent symptoms despite conservative management. Typical clinical symptoms of IDH include abdominal pain and vomiting. Diagnosis of IDH can be confirmed by imaging techniques, such as magnetic resonance imaging or computed tomography and upper gastrointestinal endoscopy. Duodenal hematoma is mainly treated by drainage, which includes open surgery drainage and percutaneous transhepatic cholangial drainage, both causing great trauma. Here we present a case of massive IDH following ERCP, which was successfully managed by minimally invasive management: intranasal hematoma aspiration combined with needle knife opening under a duodenoscope.

25.  Cost-Effective Treatment of Patients with Symptomatic Cholelithiasis and Possible Common Bile Duct Stones 
Journal of the American College of Surgeons  2011;212(6):1049-1060.e1-7.
Clinicians must choose a treatment strategy for patients with symptomatic cholelithiasis without knowing whether common bile duct (CBD) stones are present. The purpose of this study was to determine the most cost-effective treatment strategy for patients with symptomatic cholelithiasis and possible CBD stones.
Study Design
Our decision model included five treatment strategies: (1) laparoscopic cholecystectomy (LC) alone followed by expectant management, (2) preoperative endoscopic retrograde cholangiopancreatography (ERCP) followed by LC, (3) LC with intraoperative cholangiography (IOC) ± common bile duct exploration (CBDE), (4) LC followed by postoperative ERCP, and (5) LC with IOC ± postoperative ERCP. The rates of successful completion of diagnostic testing and therapeutic intervention, test characteristics (sensitivity and specificity), morbidity, and mortality for all procedures are from current literature. Hospitalization costs and lengths of stay are from the 2006 National CMS data. The probability of CBD stones was varied from 0% to 100% and the most cost-effective strategy was determined at each probability.
Across the CBD stone probability range of 4% to 100%, LC with IOC ± ERCP was the most cost-effective. If the probability was 0%, LC alone was the most cost-effective. Our model was sensitive to one health input: specificity of IOC, and three costs: cost of hospitalization for LC with CBDE, cost of hospitalization for LC without CBDE, and cost of LC with IOC.
The most cost-effective treatment strategy for the majority of patients with symptomatic cholelithiasis is LC with routine IOC. If stones are detected, CBDE should be forgone and the patient referred for ERCP.
