Laparoscopy-assisted surgery, fast-track perioperative treatment are both increasingly used in colorectal cancer treatment, for their short-time benefits of enhanced recovery and short hospital stays. However, the benefits of the integration of the Laparoscopy-assisted surgery, fast-track perioperative treatment, and even with the Xelox chemotherapy, are still unknown. In this study, the three treatments integration is defined as "Fast Track Multi-Discipline Treatment Model" for colorectal cancer and this model extends the benefits to the whole treatment process of colorectal cancer. The main purpose of the study is to explore the feasibility of "Fast Track Multi-Discipline Treatment" model in treatment of colorectal cancer.
The trial is a prospective randomized controlled study with 2 × 2 balanced factorial design. Patients eligible for the study will be randomized to 4 groups: (I) Laparoscopic surgery with fast track perioperative treatment and Xelox chemotherapy; (II) Open surgery with fast track perioperative treatment and Xelox chemotherapy; (III) Laparoscopic surgery with conventional perioperative treatment and mFolfox6 chemotherapy; (IV) Open surgery with conventional perioperative treatment and mFolfox6 chemotherapy. The primary endpoint of this study is the hospital stays. The secondary endpoints are the quality of life, chemotherapy related adverse events, surgical complications and hospitalization costs. Totally, 340 patients will be enrolled with 85 patients in each group.
The study initiates a new treatment model "Fast Track Multi-Discipline Treatment" for colorectal cancer, and will provide feasibility evidence on the new model "Fast Track Multi-Discipline Treatment" for patients with colorectal cancer.

A fast-track perioperative procedure may achieve the same low-risk, low-morbidity results for laparoscopic colectomy patients as seen with more conventional lengths of hospital stay.
A short hospital stay is one of the main advantages of the laparoscopic surgical technique. The process of developing and studying the “fast-track” process has contributed to a better understanding of the elements of perioperative care and has resulted in the reduction in length of stay (LOS) after colectomies. As we follow and refine this well-recognized multimodal approach, further decreases in the LOS can be expected. We present 2 octogenarian patients who, after receiving laparoscopic hemicolectomies for malignant disease, were discharged home <24 hours after their operations. Postoperative follow-ups did not show any adverse reaction to the early discharge. Modifying the multimodal perioperative technique with further refinement to the surgical technique appears to allow patients to be discharged home in the first 24 hours following laparoscopic colectomy.

During the last two decades the use of laparoscopic resection and a multimodal approach known as an enhanced recovery programme, have been major changes in colorectal perioperative care. Clinical outcome improves using laparoscopic surgery to resect colorectal cancer but until recently no multicentre trial evidence had been reported regarding whether the benefits of laparoscopy still exist when open surgery is optimized within an enhanced recovery programme. The EnROL trial (Enhanced Recovery Open versus Laparoscopic) examines the hypothesis that laparoscopic surgery within an enhanced recovery programme will provide superior postoperative outcomes when compared to conventional open resection of colorectal cancer within the same programme.
EnROL is a phase III, multicentre, randomised trial of laparoscopic versus open resection of colon and rectal cancer with blinding of patients and outcome observers to the treatment allocation for the first 7 days post-operatively, or until discharge if earlier. 202 patients will be recruited at approximately 12 UK hospitals and randomised using minimization at a central computer system in a 1:1 ratio. Recruiting surgeons will previously have performed >100 laparoscopic colorectal resections and >50 open total mesorectal excisions to minimize conversion. Eligible patients are those suitable for elective resection using either technique. Excluded patients include: those with acute intestinal obstruction and patients in whom conversion from laparoscopic to open procedure is likely. The primary outcome is physical fatigue as measured by the physical fatigue domain of the multidimensional fatigue inventory 20 (MFI-20) with secondary outcomes including postoperative hospital stay; complications; reoperation and readmission; quality of life indicators; cosmetic assessments; standardized performance indicators; health economic analysis; the other four domains of the MFI-20. Pathological assessment of surgical quality will also be undertaken and compliance with the enhanced recovery programme will be recorded for all patients.
Should this trial demonstrate that laparoscopic surgery confers a significant clinical and/or health economic benefit this will further support the transition to this type of surgery, with implications for the training of surgeons and resource allocation.

Postoperative ileus (POI) is a transient loss of coordinated peristalsis precipitated by surgery and exacerbated by opioid pain medication. Ileus causes a variety of symptoms including bloating, pain, nausea, and vomiting, but particularly delays tolerance of oral diet and liquids. Thus POI is a primary determinant of hospital stay after surgery. ‘Fast-track’ recovery protocols, opioid sparing analgesia, and laparoscopic surgery reduce but do not eliminate postoperative ileus. Alvimopan is a mu opioid receptor antagonist that blocks the effects of opioids on the intestine, while not interfering with their centrally mediated analgesic effect. Several large randomized clinical trials have demonstrated that alvimopan accelerates the return of gastrointestinal function after surgery and subsequent hospital discharge by approximately 20 hours after elective open segmental colectomy. However, it has not been tested in patients undergoing laparoscopic surgery and is less effective in patients receiving nonsteroidal anti-inflammatory agents in a narcotic sparing postoperative pain control regimen. Safety concerns seen with chronic low dose administration of alvimopan for opioid bowel dysfunction have not been noted with its acute use for POI.

Laparoscopic colon surgery that incorporates multimodal perioperative care may allow patients to be discharged within the first 24 hours.
Background and Objectives:
A short hospital stay is one of the main advantages of laparoscopic surgery. Previous studies have shown that after a multimodal fast-track process, the hospital length of stay can be shortened to between 2 and 5 days. The objective of this review is to show that the hospital length of stay can, in some cases, be reduced to <24 hours.
This study retrospectively reviews a surgeon's experience with laparoscopic surgery over a 12-month period. Seven patients were discharged home within 24 hours after minimally invasive laparoscopic surgical treatment, following a modified fast-track protocol that was adopted for perioperative care.
Of the 7 patients, 4 received laparoscopic right hemicolectomy for malignant disease and 3 underwent sigmoid colectomies for recurrent diverticulitis. The mean hospital stay was 21 hours, 47 minutes; the mean volume of intraoperative fluid (lactated Ringer) was 1850 mL; the mean surgical blood loss was only 74.3 mL; the mean duration of surgery was 118 minutes; and the patients were ambulated and fed a liquid diet after recovery from anesthesia. The reviewed patients had functional gastrointestinal tracts and were agreeable to the timing of discharge. On the follow-up visit, they showed no adverse consequences such as bleeding, infection, or anastomotic leak.
Laparoscopic colon surgery that incorporated multimodal perioperative care allowed patients to be discharged within the first 24 hours. Careful postoperative outpatient follow-up is important in monitoring complications such as anastomotic leak, which may not present until postoperative day 5.

Data from this report supports the view that standardization of the operative steps in laparoscopic rectal surgery seems to limit the risk of anastomotic complications and provides clear indications for early and safe conversion to open surgery.
Background and Objectives:
The purpose of this study was to audit our results after implementation of a standardized operative approach to laparoscopic surgery for rectal cancer within a fast-track recovery program.
From January 2009 to February 2011, 100 consecutive patients underwent laparoscopic surgery on an intention-to-treat basis for rectal cancer. The results were retrospectively reviewed from a prospectively collected database. Operative steps and instrumentation for the procedure were standardized. A standard perioperative care plan was used.
The following procedures were performed: low anterior resection (n=26), low anterior resection with loop-ileostomy (n=39), Hartmann's operation (n=14), and abdominoperineal resection (n=21). The median length of hospital stay was 7 days; 9 patients were readmitted. There were 9 cases of conversion to open surgery. The overall complication rate was 35%, including 6 cases (9%) of anastomotic leakages requiring reoperation. The 30-day mortality was 5%. The median number of harvested lymph nodes was 15 (range, 2 to 48). There were 6 cases of positive circumferential resection margins. The median follow-up was 9 (range, 1 to 27) months. One patient with disseminated cancer developed port-site metastasis.
The results confirm the safety of a standardized approach, and the oncological outcomes are comparable to those of similar studies.

The present developments in colon surgery are characterized by two innovations: the introduction of the laparoscopic operation technique and fast recovery programs such as the Enhanced Recovery After Surgery (ERAS) recovery program. The Tapas-study was conceived to determine which of the three treatment programs: open conventional surgery, open 'ERAS' surgery or laparoscopic 'ERAS' surgery for patients with colon carcinomas is most cost minimizing?
The Tapas-study is a three-arm multicenter prospective cohort study.
All patients with colon carcinoma, eligible for surgical treatment within the study period in four general teaching hospitals and one university hospital will be included. This design produces three cohorts: Conventional open surgery is the control exposure (cohort 1). Open surgery with ERAS recovery (cohort 2) and laparoscopic surgery with ERAS recovery (cohort 3) are the alternative exposures. Three separate time periods are used in order to prevent attrition bias.
Primary outcome parameters are the two main cost factors: direct medical costs (real cost price calculation) and the indirect non medical costs (friction method). Secondary outcome parameters are mortality, complications, surgical-oncological resection margins, hospital stay, readmission rates, time back to work/recovery, health status and quality of life.
Based on an estimated difference in direct medical costs (highest cost factor) of 38% between open and laparoscopic surgery (alfa = 0.01, beta = 0.05), a group size of 3×40 = 120 patients is calculated.
The Tapas-study is three-arm multicenter cohort study that will provide a cost evaluation of three treatment programs for patients with colon carcinoma, which may serve as a guideline for choice of treatment and investment strategies in hospitals.
Laparoscopic colectomy has become the standard of care for elective resections; however, there are few data regarding laparoscopy in the emergency setting.
Using a prospectively collected database, we identified 94 patients who underwent an emergency colectomy between August 2005 and July 2008. Laparoscopic operations were performed in 42 patients and were compared to 25 who were suitable for laparoscopy but received open colectomy.
The groups had similar demographics with no difference in age, gender or surgical indications. Blood loss was lower (118ml vs. 205ml, p <0.01) and postoperative stay shorter (8 vs. 11 days, p = 0.02) in the laparoscopic patients, and perioperative mortality rates were similar between the two groups (1 vs. 3, p = 0.29).
With increasing experience, laparoscopic colectomy is a feasible option in certain emergency situations and is associated with shorter hospital stay, less morbidity, and similar mortality to that of open operation.

In this account, addition of alvimopan to a standard perioperative recovery pathway decreased length of stay and incidence of postoperative ileus for elective laparoscopic colectomy.
Background and Objectives:
Alvimopan, a peripherally acting mu-opioid receptor antagonist, decreased time to gastrointestinal recovery and hospital length of stay in open bowel resection patients in Phase 3 trials. However, the benefit in laparoscopic colectomy patients remains unclear.
A retrospective case series review was performed to study addition of alvimopan to a well-established standard perioperative recovery pathway for elective laparoscopic colectomy. The main outcome measures were length of stay and incidence of charted postoperative ileus. Wilcoxon and chi-square tests were used to calculate P values for length of stay and postoperative ileus endpoints, respectively.
Demographic/baseline characteristics from the 101 alvimopan and 64 pre-alvimopan control patients were generally comparable. Mean length of stay in the alvimopan group was 1.55 days shorter (alvimopan, 2.81±0.95 days; control, 4.36±2.4 days; P<.0001). The proportion of patients with postoperative ileus was lower in the alvimopan group (alvimopan, 2%; control, 20%; P<.0001).
In this case series, addition of alvimopan to a standard perioperative recovery pathway decreased length of stay and incidence of postoperative ileus for elective uncomplicated laparoscopic colectomy. The improvement in the mean length of stay for patients who receive alvimopan is a step forward in achieving a fast-track surgery model for elective laparoscopic colectomies.

Purpose. Short hospital stay and equal or reduced complication rates have been demonstrated after fast track open colonic surgery. However, fast track principles of perioperative care can be difficult to implement and often require increased nursing staff because of more concentrated nursing tasks during the shorter hospital stay. Specific data on nursing requirements after laparoscopic surgery are lacking. The purpose of the study was to evaluate the effect of operative technique (open versus laparoscopic operation), but without changing nurse staffing or principles for peri- or postoperative care, that is, without implementing fast track principles, on length of stay after colorectal resection for cancer. Methods. Records of all patients operated for colorectal cancer from November 2004 to December 2008 in our department were reviewed. No specific patients were selected for laparoscopic repair, which was solely dependent on the presence of two specific surgeons at the same time. Thus, the patients were not selected for laparoscopic repair based on patient-related factors, but only on the simultaneous presence of two specific surgeons on the day of the operation. Results. Of a total of 540 included patients, 213 (39%) were operated by a laparoscopic approach. The median hospital stay for patients with a primary anastomosis was significantly shorter after laparoscopic than after conventional open surgery (5 versus 8 days, P < 0.001) while there was no difference in patients receiving a stoma (10 versus 10 days, ns), with no changes in the perioperative care regimens. Furthermore there were significant lower blood loss (50 versus 200 mL, P < 0.001) and lower complication rate (21% versus 32%, P = 0.006) in the laparoscopic group. Conclusion. Implementing laparoscopic colorectal surgery in our department resulted in shorter hospital stay without using fast track principles for peri- and postoperative care in patients not receiving a stoma during the operation. Consequently, we aimed to reduce hospitalisation without increasing cost in nursing staff per hospital bed. Length of stay was not reduced in patients receiving a stoma pointing at this group for specific intervention in the future. Furthermore, the complication rate was reduced in the laparoscopic group.
To investigate fast-track rehabilitation concept in terms of a measurable effect on the early recovery after total knee arthroplasty (TKA).
This was an open, randomized, prospective clinical study, comparing the fast-track rehabilitation—a pathway-controlled early recovery program (Joint Care®)—with standard postoperative rehabilitation care, after TKA. Overall, 147 patients had TKA (N = 74 fast-track rehabilitation,N = 73 standardrehabilitation). The fast-track rehabilitation patients received a group therapy, early mobilization (same day as surgery) and 1:1 physiotherapy (2 h/day). Patient monitoring occurred over 3 months (1 pre- and 4 post-operative visits). The standard rehabilitation group received individual postoperative care according to the existing protocol, with 1:1 physiotherapy (1 h/day). The cumulative American Knee Society Score (AKSS) was the primary evaluation variable, used to detect changes in joint function and perception of pain. The secondary evaluation variables were WOMAC index score, analgesic drug consumption, length of stay (LOS), and safety.
After TKA, patients in the fast-track rehabilitation group showed enhanced recovery compared with the standardrehabilitation group, as based on the differences between the groups for the cumulative AKSS (p = 0.0003), WOMAC index score (<0.0001), reduced intake of concomitant analgesic drugs, reduced LOS (6.75 vs. 13.20 days, p < 0001), and lower number of adverse events.
For TKA, implementation of pathway-controlled fast-track rehabilitation is achievable and beneficial as based on the AKSS and WOMAC score, reduced intake of analgesic drugs, and reduced LOS.

AIM: To analyze our results after the introduction of a fast-track (FT) program after laparoscopic liver surgery in our Hepatobiliarypancreatic Unit.
METHODS: All patients (43) undergoing laparoscopic liver surgery between March 2004 and March 2010 were included and divided into two consecutive groups: Control group (CG) from March 2004 until December 2006 with traditional perioperative cares (17 patients) and fast-track group (FTG) from January 2007 until March 2010 with FT program cares (26 patients). Primary endpoint was the influence of the program on the postoperative stay, the amount of re-admissions, morbidity and mortality. Secondarily we considered duration of surgery, use of drains, conversion to open surgery, intensive cares needs and transfusion.
RESULTS: Both groups were homogeneous in age and sex. No differences in technique, time of surgery or conversion to open surgery were found, but more malignant diseases were operated in the FTG, and then transfusions were higher in FTG. Readmissions and morbidity were similar in both groups, without mortality. Postoperative stay was similar, with a median of 3 for CG vs 2.5 for FTG. However, the 80.8% of patients from FTG left the hospital within the first 3 d after surgery (58.8% for CG).
CONCLUSION: The introduction of a FT program after laparoscopic liver surgery improves the recovery of patients without increasing complications or re-admissions, which leads to a reduction of the stay and costs.

Laparoscopic procedure is a rapid developed technique in colorectal surgery. In this investigation we aim at assessing the diversities of short-term and medium-term clinical outcomes of laparoscopic-assisted versus open surgery for colorectal cancer.
A total number of 519 patients with non-metastatic colorectal cancer were enrolled for this study. The patients underwent either laparoscopic-assisted surgery (LAP) (n = 254) or open surgery (OP) (n = 265). Surgical techniques, perioperative managements and clinical follow-ups were standardized. Short-term perioperative data and medium-term recurrence and survival were compared and analyzed between the two groups.
There were no differences in perioperative parameters between the two groups except in regards to a trend of faster recovery in laparoscopic procedures. There was no statistically significant difference in postoperative complications, reoperation rate, or perioperative mortality. Statistically significant differences in a faster return of gastrointestinal function and shorter hospital stay were identified in favor of laparoscopic-assisted resection. In colon and rectal cancer cases separately, the overall survival, cancer-free survival and recurrence rate were similar in two groups. There was also no tendency of significant differences in overall survival, cancer-free survival and recurrence in stage I-II and stage III patients in two cancer categories between the two groups, respectively. pT, lymph node metastasis, and clinical stage were independent predictors of overall death risk, while pT, pN, lymph node metastasis and clinical stage were found to be the independent predictors of recurrence risk in enrolled patients database.
Laparoscopic-assisted procedure has more benefits on postoperative recovery, while has the same effects on medium-term recurrence and survival compared with open surgery in the treatment of non-metastatic colorectal cancer.
A prospective case series of single incision multiport laparoscopic colorectal resections for malignancy using conventional laparoscopic trocars and instruments is described.
MATERIALS AND METHODS:
Eleven patients (seven men and four women) with colonic or rectal pathology underwent single incision multiport laparoscopic colectomy/rectal resection from July till December 2010. Four trocars were placed in a single transumblical incision. The bowel was mobilized laparoscopically and vessels controlled intracorporeally with either intra or extracorporeal anastomosis.
Three patients had carcinoma in the caecum, one in the hepatic flexure, two in the rectosigmoid, one in the descending colon, two in the rectum and two had ulcerative pancolitis (one with high grade dysplasia and another with carcinoma rectum). There was no conversion to standard multiport laparoscopy or open surgery. The median age was 52 years (range 24-78 years). The average operating time was 130 min (range 90-210 min). The average incision length was 3.2 cm (2.5-4.0 cm). There were no postoperative complications. The average length of stay was 4.5 days (range 3-8 days). Histopathology showed adequate proximal and distal resection margins with an average lymph node yield of 25 nodes (range 16-30 nodes).
Single incision multiport laparoscopic colorectal surgery for malignancy is feasible without extra cost or specialized ports/instrumentation. It does not compromise the oncological radicality of resection. Short-term results are encouraging. Long-term results are awaited.

Enhanced recovery after surgery (ERAS) employs a multimodal perioperative care pathway with the aim of attenuating the stress response to surgery and accelerating recovery. It has been difficult to determine the relative importance of some of the individual components of these pathways such as epidural analgesia and laparoscopic colorectal surgery. Some argue that only a rigid adherence to the published ERAS protocol can achieve the proposed benefits of fast-track surgery. In this article, we explore some of the areas where the evidence base may be changing and ask whether a more flexible and individualised approach should be considered.

Fast-track surgery is a novel approach which uses a multimodal package of changes to traditional surgical care to reduce the stress response evoked by surgery allowing for enhanced recovery times. The depth of understanding and application of fast-track principles to general surgical practice by consultant surgeons is unknown.
MATERIALS AND METHODS
‘Core management features’ central to published fast-track general surgical studies were identified following a comprehensive Medline literature search. The knowledge and application of these features were examined in a postal questionnaire sent to 116 general surgeons in a single region.
Of respondents, 31% indicated they were currently using fast-track surgery (the ‘fast-trackers'). The number of fast-track compliant responses was calculated for each consultant (range, 1–12 of 14). Mean scores for ‘fast-trackers’ of 8.45 (± 2.188) and ‘non-fast-trackers’ of 6.16 (± 2.352) showed no significant differences (P > 0.6). The ‘fast-trackers’ median estimated length of stay (LOS) was 5 days (inter-quartile range [IQR], 4–7) which was significantly lower than the 7 day (IQR 6–8) LOS estimates given by the ‘non-fast-trackers’ (P < 0.01).
Despite estimating reduced LOS, no significant difference in total fast-track compliant responses was found between the ‘fast-tracker’ and ‘non-fast-tracker’ groups. The ‘fast-trackers’ estimated LOS of 5 days is 2.5 times the 2 day LOS reported in the published fast-track studies. A significant gap exists between the perception and realisation of fast-track methodology amongst general surgeons.

Several multi-institutional prospective randomized trials have demonstrated short-term benefits using laparoscopy. Now the laparoscopic approach is accepted as an alternative to open surgery for colon cancer. However, in prior trials, the transverse colon was excluded. Therefore, it has not been determined whether laparoscopy can be used in the setting of transverse colon cancer. This study evaluated the peri-operative clinical outcomes and oncological quality by pathologic outcomes of laparoscopic surgery for transverse colon cancer.
Materials and methods
Analysis of the medical records of patients who underwent laparoscopic colorectal resection from August 2004 to November 2007 was made. Computed tomography, barium enema, and colonoscopy were performed to localize the tumor preoperatively. Extended right hemicolectomy, transverse colectomy, and extended left hemicolectomy were performed for transverse colon cancer. Surgical outcomes and pathologic outcomes were compared between transverse colon cancer (TCC) and other site colon cancer (OSCC).
Of the 312 colorectal cancer patients, 94 patients underwent laparoscopic surgery for OSCC, and 34 patients underwent laparoscopic surgery for TCC. Patients with TCC were similar to patients with OSCC in age, gender, body mass index, operating time, blood loss, time to pass flatus, start of diet, hospital stay, tumor size, distal resection margin, proximal resection margin, number of lymph nodes, and radial margin. One case in TCC and three cases in OSCC were converted to open surgery.
Laparoscopic surgery for transverse colon cancer and OSCC had similar peri-operative clinical and acceptable pathological outcomes.

Colorectal resection was traditionally associated with significant morbidity and prolonged stay in hospital. Laparoscopic colorectal resection was first described in 1991 as a minimally invasive form of colorectal surgery. It was later on assessed by multiple randomized controlled trials and meta-analysis and was found to be associated with a faster recovery, lower complication rates and a shorter stay in hospital compared with open resection. To assess the effect of enhanced recovery after surgery (ERAS) program on postoperative length of stay after elective colorectal resections, a literature review was conducted, supplemented by the results of 111 ERAS colorectal resections at regional NWS Hospital using a protocol based on the Fast Track approach described by Kehlet in 1999. ERAS has been shown to improve postoperative recovery, reduce length of stay and enhance early return to normal function when compared with traditional colorectal surgical protocols. The role of laparoscopic surgery in colorectal resections within a fast-track (ERAS) program is controversial. The current evidence suggests that within such a program, there is no difference between laparoscopic and open colorectal surgery in terms of postoperative recovery rates or length of hospital stay.

Purpose: We conducted a meta-analysis to evaluate and compare the short- and long-term results of laparoscopy-assisted colectomy (LAC) and open colectomy (OC) for colon cancer.
Methods: We searched MEDLINE, EMBASE, Science Citation Index, and Cochrane Controlled Trial Register for relevant papers published between January 1990 and October 2011 by using the search terms “laparoscopy,” “laparoscopy-assisted,” “surgery,” “colectomy,” “colon cancer,” and “randomized clinical trials (RCTs)”. We analyzed the outcomes of each type of surgery over short- and long-term periods.
Results: We selected 12 papers reporting RCTs that compared LAC with OC for colon cancer. Our meta-analysis included 4614 patients with colon cancer; of these, 2444 had undergone LAC and 2170 had undergone OC. In the short-term period, we found that the rates of overall postoperative complications and ileus in LAC were lower than in OC groups. LAC was associated with a reduction in intraoperative blood loss, a shorter duration of time to resumption and hospital stay, and lower rates of overall complication and ileus over the short-term, but with similar long-term oncologic outcomes such as overall and cancer-related mortality, overall recurrence, local recurrence, distant metastasis, and wound-site recurrence, compared to OC.
Conclusions: It is suggested that LAC may be preferred to OC for colon cancer.

Laparoscopic colectomy has been proven oncologically equivalent to conventional surgery and is now generally agreed to offer patients a reduced length of stay, shorter recovery times, and improved cosmesis. In contrast, acceptance of laparoscopic proctectomy for rectal cancer has been much delayed and the enthusiasm of early studies has met considerable skepticism. For rectal cancer, it has been demonstrated that there is considerable variation between surgeons in disease-free survival and local pelvic recurrence after open proctectomy for rectal cancer. These differences are likely to be magnified when the technical challenge of laparoscopy is added to proctectomy. Minimally invasive approaches to rectal cancer need to demonstrate equivalent oncologic outcomes and maintenance or improvement in quality of life. This review will outline the current evidence for laparoscopy as a treatment option for patients with rectal cancer, emphasize the need for standardized approaches among multidisciplinary teams, and highlight the technical details of different laparoscopic operations for rectal cancer.

Laparoscopic colectomy for colon cancer has been compared with open colectomy in randomized controlled trials, but these studies may not be generalizable because of strict enrollment and exclusion criteria which may explicitly or inadvertently exclude older individuals due to associated comorbidities. Previous studies of older patients undergoing laparoscopic colectomy have generally focused on short-term outcomes. The goals of this cohort study were to identify predictors of laparoscopic colectomy in an older population in the United States and to compare short-term and long-term outcomes.
Patients aged 65 years or older with incident colorectal cancer diagnosed 1996-2002 who underwent colectomy within 6 months of cancer diagnosis were identified from the linked Surveillance, Epidemiology, and End Results-Medicare database. Laparoscopic and open colectomy patients were compared with respect to length of stay, blood transfusion requirements, intensive care unit monitoring, complications, 30-day mortality, and long-term survival. We adjusted for potential selection bias in surgical approach with propensity score matching.
Laparoscopic colectomy cases were associated with left-sided tumors; areas with higher population density, income, and education level; areas in the western United States; and National Cancer Institute-designated cancer centers. Laparoscopic colectomy cases had shorter length of stay and less intensive care unit monitoring. Although laparoscopic colectomy patients (n = 424) had fewer complications (21.5% versus 26.3%), lower 30-day mortality (3.3% versus 5.8%), and longer median survival (6.6 versus 4.8 years) compared with open colectomy patients (n = 27,012), after propensity score matching these differences disappeared.
In this older population, laparoscopic colectomy practice patterns were associated with factors which likely correlate with tertiary referral centers. Although short-term and long-term survival are comparable, laparoscopic colectomy offers shorter hospitalizations and less intensive care.
Crohn's disease represents a challenging operative dilemma. The nature of the disease increases the technical complexity of operations, their morbidity, and the likelihood of multiple operations. In this setting, the advantages of laparoscopic surgery, including shorter hospital stays, less adhesion formation, fewer wound complications, and faster recovery of bowel function, are particularly beneficial to the patient. Patients with Crohn's disease requiring operations in the elective and semi-elective setting can all be approached initially laparoscopically. The surgeon's skill set should include extensive experience in advanced laparoscopic bowel surgery as well as open management of Crohn's disease and its complications. Strict adherence to the basic tenet of bowel preservation is imperative. The operations most commonly performed for Crohn's disease include diagnostic laparoscopy, stricturoplasty, small bowel resection, ileocolic resection, colectomy, repair of fistulae, and gastrojejunostomy for bypass of gastric or duodenal disease. Postoperative management includes resumption of steroids, typically without the need for “stress-dosing,” bowel rest for a short period, and pain control, which is also less than that experienced with a laparotomy.

Laparoscopic colectomy is now widely applied to cases of malignancy, supported by early data from several large randomized controlled trials. Long-term follow-up is now available from those trials, supporting equivalency of cancer-free and overall survival for open and laparoscopic resections. This promising data has inspired further exploration of other applications of laparoscopic techniques, including use of single incision laparoscopy. This article reviews recent reports of long-term data for colorectal cancer resection from four randomized, prospective international trials.

Laparoscopy continues to be increasingly adopted for elective colorectal resections. However, its role in an emergency setting remains controversial. The aim of this study was to compare the outcomes between laparoscopic and open colectomies performed for emergency colorectal conditions.
A retrospective review of all patients who underwent emergency laparoscopic colectomies for various surgical conditions was performed. These patients were matched for age, gender, surgical diagnosis and type of surgery with patients who underwent emergency open colectomies.
Twenty-three emergency laparoscopic colectomies were performed from April 2006 to October 2011 for patients with lower gastrointestinal tract bleeding (6), colonic obstruction (4) and colonic perforation (13). The hand-assisted laparoscopic technique was utilized in 15 cases (65.2%). There were 4 (17.4%) conversions to the open technique. The operative time was longer in the laparoscopic group (175 minutes vs. 145 minutes, P = 0.04), and the duration of hospitalization was shorter in the laparoscopic group (6 days vs. 7 days, P = 0.15). The overall postoperative morbidity rates were similar between the two groups (P = 0.93), with only 3 patients in each group requiring postoperative surgical intensive-care-unit stays or reoperations. There were no mortalities. The cost analysis did not demonstrate any significant differences in the procedural (P = 0.57) and the nonprocedural costs (P = 0.48) between the two groups.
Emergency laparoscopic colectomy in a carefully-selected patient group is safe. Although the operative times were longer, the postoperative outcomes were comparable to those of the open technique. The laparoscopic group did not incur a higher cost.

A perioperative anaesthetic management that aims to facilitate tracheal extubation of patients within 1-6 hrs after cardiac surgery is called “fast-track”. Main advantage of “fast-track” method is better usage of medical resources and lowering hospital costs without increasing morbidity and mortality of the patients. Standard fast-track protocols contain short acting anaesthetic agents, smaller incisions and decreased pump times without hypothermia. In this study we compared two short acting opioid drugs, fentanyl versus Sufentanil when used as a part of the balanced anaesthesia technique for fast track in cardiac surgery patients & evaluated the time taken for extubation, haemodynamic stability, analgesia requirements & incidence of awareness. The results from the study show that both agents provide good haemodynamic stability and postoperative analgesia. Although Sufentanil provides earlier extubation, both agents reduce the ICU stay equally. In conclusion both agents can be used effectively for fasttrack cardiac anaesthesia.
