Does a laparoscopic approach to total abdominal colectomy and proctocolectomy offer advantages?

Impact of single-incision laparoscopic surgery on postoperative analgesia requirements after total colectomy for ulcerative colitis: a propensity-matched comparison with multiport laparoscopy

AIM

To compare the requirements for postoperative analgesia in patients with ulcerative colitis after single-incision versus multiport laparoscopic total colectomy.

METHOD

All patients undergoing single-incision or multiport laparoscopic total colectomy as a first stage in the surgical treatment of ulcerative colitis between 2010 and 2016 at the University Hospital of Leuven were included. The cumulative dose of postoperative patient-controlled analgesia was used as the primary end-point. A Z-transformation was performed combining values for patient-controlled epidural analgesia and patient-controlled intravenous analgesia, resulting in one hybrid outcome variable. The two groups were matched using propensity scores. Subgroup analysis was performed to analyse the impact of extraction site on postoperative pain.

RESULTS

A total of 81 patients underwent total colectomy for ulcerative colitis (median age 35 years). Thirty patients underwent single-incision laparoscopy, while 51 patients had a multiport approach. The mean normalized patient-controlled analgesia dose was significantly lower in patients undergoing single-incision laparoscopy (-0.33 vs 0.46, P < 0.001). This difference was no longer significant in subgroup analysis for patients with stoma site specimen extraction (P = 0.131). The odds of receiving tramadol postoperatively was 3.66 times lower after single-incision laparoscopy (P = 0.008). The overall morbidity rate was 32.1% (26/81). The mean Comprehensive Complication Index in single-incision and multiport laparoscopy group was 18.33 and 21.39, respectively (P = 0.506). Hospital stay was significantly shorter after single-incision laparoscopic surgery (6.3 days vs 7.6 days, P = 0.032).

CONCLUSION

Single-incision total colectomy was associated with lower postoperative analgesia requirements and shorter hospital stay, with comparable morbidity. However, the specimen extraction site played a significant role in postoperative pain control.

Surgery in ulcerative colitis: When? How?

Ulcerative Colitis (UC) is an idiopathic chronically-remitting inflammatory bowel disorder characterized by a contiguous inflammation of the colonic mucosa affecting the rectum that generally extends proximally in a continuous manner through the entire colon. Patients typically experience intermittent exacerbations, with symptoms characterized by bloody diarrhea associated with urgency and tenesmus. The anatomical extent of mucosal involvement is the most important factor determining disease course and is an important predictor of colectomy. The precise etiology of UC is unknown. However, a combination of genetic predisposition and environmental factors seems to have a key role in the development of the disease. UC usually is mildly active but it can be a life-threatening condition because of colonic and systemic complications, and later in the disease course due to the development of colorectal cancer. Interestingly, even if pathogenetic features detected in patients with sporadic CRC can be also found in UC-related colorectal cancer (UC-CRC), this latter is, usually, driven by an inflammation-driven pathway rising from a non-neoplastic inflammatory epithelium to dysplasia to cancer. Thus, a long-term follow-up with colonoscopy surveillance has been recommended. Approximately 15% of UC patients develop an acute attack of severe colitis, and 30% of these patients require colectomy. The initial treatment strategy in UC typically follows the traditional step-up approach. One third of the patients will not respond to steroid therapy and cyclosporine and infliximab are the most common salvage agents employed in these cases in order to avoid emergent surgery. Unfortunately, although a significant short-term benefit have been observed after infliximab treatment, the colectomy rate have remained stable. Surgery in UC depends on the stage of the disease as well as patient's status and is divided into the following settings: urgent, emergent and elective. Despite many efforts the surgical management of UC remains a significant challenge. A multidisciplinary management of UC is key in order to define the best timing and the best procedure for each patient in an individualized basis.

Rationalisation of the surgical technique for minimally invasive laparoscopic ileal pouch-anal anastomosis after previous total colectomy for ulcerative colitis

INTRODUCTION:

No previous study clearly focuses on laparoscopic technique to perform the second stage surgery (proctectomy with ileal pouch-anal anastomosis [IPAA]) after total colectomy for acute/severe ulcerative colitis (UC). We describe the procedural steps for a simple and rational minimally invasive second stage surgery, reporting intra- and short-term post-operative results.

PATIENTS AND METHODS:

During the period December 2014–December 2015, 10 consecutive patients (8 males and 2 females) with mean age of 48 years underwent laparoscopic proctectomy and IPAA adopting our novel approach. They were operated 3 months after the previous total colectomy which has been performed, respectively, for acute (three patients) or severe (seven patients) UC. Intraoperative data and post-operative complications, divided as minor and major, were recorded and analysed. A body image questionnaire was administered to all patients to evaluate the cosmetic results of the procedure.

RESULTS:

Overall mean surgical time was 235 ± 49 min. During the post-operative course, three patients required morphine for >48 h, no patient needed blood transfusion and bowel movements recovery happened as mean during the 2^nd day. No early major complications happened. Two patients (20%) developed peri-ileostomic wound infection at the right flank. Only one patient (10%) suffered from ileal-anal anastomotic dehiscence, conservatively treated till resolution. The average length of hospital stay was 8 ± 2 days. The body image questionnaire showed in all patients an extreme satisfaction about the results obtained (mean value = 59/64 points).

CONCLUSIONS:

Through three standardised surgical steps easily reproducible, we describe an almost scar-less procedure able to optimise the intraoperative time with good post-operative results in terms of complications and cosmesis.

Subtotal colectomy for ulcerative colitis: lessons learned from a tertiary centre

AIM

Subtotal colectomy (STC) is a well-established treatment for complicated and refractory ulcerative colitis (UC). A laparoscopic approach offers potentially improved outcomes. The aim of the study was to report our experience with STC for UC in a single large centre.

METHOD

From January 2007 to May 2015, all consecutive patients undergoing STC for UC were retrospectively analysed from a prospectively managed database. Patients with known Crohn's disease or those undergoing one-stage procedures were excluded. Demographics, perioperative outcomes and second-stage procedures were analysed.

RESULTS

During the study period, 151 STCs were performed for UC [100 emergency (66%) and 51 elective (34%)]. Acute severe colitis refractory to therapy was the most common indication (62%). Overall, 117 laparoscopic (78%) and 34 open STCs were performed, with a conversion rate of 14.5%. Mortality and morbidity rates were 0.7% and 38%, respectively. Whilst operative time was shorter for open STC (by 75 min; P = 0.001), there were fewer complications (32% vs 62%; P = 0.002) and a shorter hospital stay (by 6.9 days; P = 0.0002) following laparoscopic STC. Fewer complications and shorter hospital stay were also observed after elective STC. Patients undergoing laparoscopic STC were more likely to undergo a restorative second-stage procedure than those having open STC (75% vs 50%; P = 0.03).

CONCLUSION

Laparoscopic STC for UC is feasible and safe, even in the emergency situation. A laparoscopic approach may offer advantages in terms of lower morbidity and reduced length of stay. Elective resection may offer similar advantages and is best performed whenever possible.

Safety, feasibility, and short-term outcomes in 588 patients undergoing minimally invasive ileal pouch-anal anastomosis: a single-institution experience

PURPOSE

A laparoscopic approach to proctocolectomy and ileal pouch-anal anastomosis (IPAA) in patients with chronic ulcerative colitis and familial adenomatous polyposis has grown in popularity secondary to reports of small series demonstrating short-term patient benefits. Limited data exist in large numbers of patients undergoing laparoscopic ileal pouch-anal anastomosis (L-IPAA). We aimed to analyze surgical outcomes in a large cohort of patients undergoing L-IPAA.

METHODS

From a prospectively maintained surgical database, 30-day surgical outcome data were reviewed for all L-IPAA performed for chronic ulcerative colitis and familial adenomatous polyposis from 1999 to 2012. Demographics, operative approach, and operative and postoperative complications were analyzed.

RESULTS

A total of 588 L-IPAA ileal pouch-anal anastomoses were performed predominantly for chronic ulcerative colitis (93.9 %). The mean age was 36.2 years, and 54.3 % were male, with a mean BMI of 24.1 kg/m(2). Three-stage operations were performed in 17.7 %. The mean operating time of the patients excluding 3-stage operation was 269.4 min. Minimally invasive techniques included hand-assist in 55 % and straight laparoscopy in 45 %. Conversion to open occurred in 8.8 %. Median length of stay was 5 days. There was no mortality. Complications occurred in 36.9 % of patients: Clavien grade I (17.5 %), grade II (72.8 %), and grade III (9.7 %). Analysis of the grouped data over time demonstrated a statistically significant reduction in operative time (p < 0.001) and an increase in the ratio of hand-assisted over straight laparoscopy (p = 0.001).

CONCLUSIONS

Minimally invasive IPAA performed using either a laparoscopic or hand-assisted technique is safe, can be performed with low conversion rates, and confers beneficial perioperative outcomes.

Systematic review of emergent laparoscopic colorectal surgery for benign and malignant disease

Laparoscopic surgery has become well established in the management of both and malignant colorectal disease. The last decade has seen increasing numbers of surgeons trained to a high standard in minimally-invasive surgery. However there has not been the same enthusiasm for the use of laparoscopy in emergency colorectal surgery. There is a perception that emergent surgery is technically more difficult and may lead to worse outcomes. The present review aims to provide a comprehensive and critical appraisal of the available literature on the use of laparoscopic colorectal surgery (LCS) in the emergency setting. The literature is broadly divided by the underlying pathology; that is, inflammatory bowel disease, diverticulitis and malignant obstruction. There were no randomized trials and the majority of the studies were case-matched series or comparative studies. The overall trend was that LCS is associated with shorter hospital stay, par or fewer complications but an increased operating time.Emergency LCS can be safely undertaken for both benign and malignant disease providing there is appropriate patient selection, the surgeon is adequately experienced and there are sufficient resources to allow for a potentially more complex operation.

Outcomes and cost of diverted versus undiverted restorative proctocolectomy

BACKGROUND

Some observational studies suggest that diversion during restorative proctocolectomy mitigates the risk of anastomotic complications. However, diversion has its own costs and complications. The aim of this study was to compare the cost and outcomes of diverted to undiverted restorative proctocolectomy.

METHODS

This study took advantage of a natural experiment within one surgical department to understand the clinical and financial implications of diversion during restorative proctocolectomy. For the last 10 years, two surgeons routinely diverted all patients undergoing restorative proctocolectomy, and two other surgeons routinely did not. The medical records of 288 consecutive restorative proctocolectomy patients were reviewed. Minimum follow-up time was 1 year, with an average of 4.7 years. Complications rates and costs of care were collected.

RESULTS

There were no significant differences between rates of anastomotic leak, fistula, or hernias in diverted versus undiverted patients. The odds of having stricture (odds ratio (OR) = 17.08, P < 0.001) and small bowel obstruction (OR = 5.05, P = 0.02) were both significantly higher in diverted patients. The average cost per patient was $43,000 more in the routinely diverted patients.

CONCLUSION

Undiverted restorative proctocolectomy may be the highest value procedure with the most favorable outcomes at the lowest cost.

Risk of desmoid tumours after open and laparoscopic colectomy in patients with familial adenomatous polyposis

BACKGROUND

Desmoid tumour (DT) is a main cause of death after prophylactic colectomy in patients with familial adenomatous polyposis (FAP). The purpose of this study was to evaluate the impact of prophylactic laparoscopic colectomy on the risk of developing DT in patients with FAP.

METHODS

The database of a single institution was reviewed. Patients with classical FAP with defined genotype who underwent either open or laparoscopic colectomy between 1947 and 2011 were included in the study. The impact of various demographic and clinical features on the risk of developing DT was assessed.

RESULTS

A total of 672 patients underwent prophylactic colectomy: 602 by an open and 70 by a laparoscopic approach. With a median (range) follow-up of 132 (0-516) months in the open group and 60 (12-108) months in the laparoscopic group, 98 patients (16·3 per cent) developed DT after an open procedure compared with three (4 per cent) following laparoscopic surgery. The estimated cumulative risk of developing DT at 5 years after surgery was 13·0 per cent in the open group and 4 per cent in the laparoscopic group (P = 0·042). In multivariable analysis, female sex (hazard ratio (HR) 2·18, 95 per cent confidence interval 1·40 to 3·39), adenomatous polyposis coli mutation distal to codon 1400 (HR 3·85, 1·90 to 7·80), proctocolectomy (HR 1·67, 1·06 to 2·61), open colectomy (HR 6·84, 1·96 to 23·98) and year of surgery (HR 1·04, 1·01 to 1·07) were independent risk factors for the diagnosis of DT after prophylactic surgery.

CONCLUSION

Laparoscopic surgery decreased the risk of DT after prophylactic colectomy in patients with FAP.

Laparoscopy in Crohn's disease

In Crohn's disease (CD) surgical management, laparoscopic approach offers several theoretical advantages over the open approach. However, the importance of inflammatory lesions associated with CD, and the frequent presence of adhesions from previous surgery have initially questioned its feasibility and safety. In the present review article we will discuss the role of laparoscopic approach for Crohn's disease surgical management, along with its potential benefits as compared to the open approach.

Complications after laparoscopic and open subtotal colectomy for inflammatory colitis: a case-matched comparison

AIM

The aim of this study was to compare the early postoperative outcome of patients undergoing laparoscopic subtotal colectomy with those undergoing open subtotal colectomy for colitis refractory to medical treatment.

METHOD

A retrospective observational study was carried out of patients who underwent subtotal colectomy for refractory colitis, at a single centre, between 2006 and 2012. Patients were matched for age, gender, American Society of Anesthesiology (ASA) grade, urgency of operation and immunosuppressant/modulator treatment. The primary outcome measure was the number of postoperative complications, classified using the Clavien-Dindo scale. Secondary end-points included procedure duration, laparoscopic conversion rates, blood loss, 30-day readmission rates and length of hospital stay.

RESULTS

Ninety-six patients were included, 39 of whom had laparoscopic surgery. Thirty-two of these were matched to similar patients who underwent an open procedure. The overall duration of the procedure was longer for laparoscopic surgery than for open surgery (median: 240 vs 150 min, P < 0.005) but estimated blood loss was less (median: 75 vs 400 ml, P < 0.005). In the laparoscopic group, 23 patients experienced 27 complications, and in the open surgery group, 23 patients experienced 30 complications. Most complications were minor (Grade I/II), and the distribution of complications, by grade, was similar between the two groups. There was no statistically significant difference in 30-day readmission rates between the laparoscopic and open groups (five readmissions vs eight readmissions, P = 0.536). Length of hospital stay was 4 days shorter for laparoscopic surgery, but this difference was not statistically significant (median: 7 vs 11 days, P = 0.159).

CONCLUSION

In patients requiring colectomy for acute severe colitis, laparoscopic surgery reduced blood loss but increased operating time and was not associated with a reduction in early postoperative complications, length of hospital stay or readmission rates.

Total abdominal colectomy for severe ulcerative colitis: does the laparoscopic approach really have benefit? Surg Endosc. 2014;28:617-625. [PMID: 24196546 DOI: 10.1007/s00464-013-3218-7]

BACKGROUND

It is still unknown to what extent the reported morbidity and recovery benefits of laparoscopic total abdominal colectomy (TAC) for severe ulcerative colitis (UC) are associated with patient selection bias. This study aimed to evaluate whether laparoscopic TAC has any advantages over open surgery after control for perioperative confounding factors.

METHODS

Patients undergoing TAC for UC during 2006-2010 were identified. Demographics, disease characteristics, and perioperative outcomes were compared between laparoscopic and open TAC. Postoperative recovery and 30-day complications were further assessed by covariate-adjusted multivariate regression models. The outcomes of different laparoscopic techniques were compared. A subgroup analysis including surgeons who routinely used both laparoscopic and open techniques was also performed.

RESULTS

Of the 412 eligible patients, the 197 patients undergoing laparoscopic TAC were significantly younger and had a decreased Charlson Comorbidity Index and ASA score, increased hemoglobin and serum albumin levels, and a smaller proportion of extensive colitis and urgent cases. Unadjusted analyses showed that intraoperative morbidity, postoperative mortality, and rates for readmission and reoperation were similar. Laparoscopic TAC was associated with a longer operative time but a decrease in blood loss, overall morbidity, ileus, and thromboembolism, as well as a faster return to bowel function and a shorter hospital stay. After covariate adjustments, laparoscopic surgery remained associated with a reduction in the time to stoma function, incidence of postoperative ileus, and hospital stay compared with open TAC. The rates of postoperative morbidity, readmission, and reoperation did not differ regardless whether the conventional multitrocar technique, hand-assisted procedure, or single-incision technique was used. Laparoscopic TAC among surgeons using both open and laparoscopic techniques was associated with recovery benefits similar to those observed in the overall study population.

CONCLUSION

The data suggest that laparoscopic TAC retains recovery advantages over open surgery even after adjustments for confounders.

Laparoscopic and open subtotal colectomies have similar short-term results

BACKGROUND

Laparoscopic subtotal colectomy (STC) is a complex procedure. It is possible that short-term benefits for segmental resections cannot be attributed to this complex procedure. This study aims to assess differences in short-term results for laparoscopic versus open STC during a 15-year single-institute experience.

METHODS

We reviewed consecutive patients undergoing laparoscopic or open elective or subacute STC from January 1997 to December 2012.

RESULTS

Fifty-six laparoscopic and 50 open STCs were performed. The operation time was significantly longer in the laparoscopic group, median 266 min (range 121-420 min), compared to 153 min (range 90-408 min) in the open group (p < 0.001). Median hospital stay showed no statistical difference, 14 days (range 1-129 days) in the laparoscopic and 13 days (range 1-85 days) in the open group. Between-group postoperative complications were not statistically different.

CONCLUSIONS

Laparoscopic STC has short-term results similar to the open procedure, except for a longer operation time. The laparoscopic approach for STC is therefore only advisable in selected patients combined with extensive preoperative counseling.

Surgical management of IBD--from an open to a laparoscopic approach

Surgery is a key feature of IBD management. Up to 70% of patients with Crohn's disease and 35% of patients with ulcerative colitis will require surgery during the course of their disease. This Review provides an overview of IBD surgical management, focusing on the potential benefits and drawbacks of laparoscopy compared with open surgery. Emergency and elective indications for both laparoscopic and open surgery are detailed for patients with ulcerative colitis and Crohn's disease. Evidence-based comparative results of these surgical approaches are discussed, along with factors that influence patient outcomes. Upcoming new techniques for IBD surgical management, including single-port surgery, are also presented.

Comparable postoperative morbidity and mortality after laparoscopic and open emergent restorative colectomy: outcomes from the ACS NSQIP. World J Surg. 2012;36:2488-2496. [PMID: 22736343 DOI: 10.1007/s00268-012-1694-x]

BACKGROUND

Laparoscopic surgery is safe and effective in the management of common abdominal emergencies. However, there is currently a lack of data about its use for emergency colorectal surgery. We hypothesized that laparoscopy can improve the postoperative outcomes of emergency restorative colon resection.

METHODS

Adult patients undergoing emergent open and laparoscopic colon resection with primary anastomosis were retrieved from the American College of Surgeons National Surgical Quality Improvement Program database for the years 2005 to 2008 inclusive. Demographic and operative characteristics, laboratory values, and postoperative outcomes were compared between patients undergoing laparoscopic and open colon resection using univariate analyses, multivariate logistic regression, and propensity score analyses.

RESULTS

A total of 341 laparoscopic (9.6 %) and 3211 (90.4 %) open colon resections were included. Patients undergoing laparoscopic surgery had a significantly lower prevalence of co-morbidities and better postoperative outcomes. On multivariate analysis, laparoscopic surgery was an independent predictor of a longer operating time (p < 0.001) and shorter total (p = 0.013) and postoperative (p = 0.004) hospital stays, but it did not affect the need for intraoperative blood transfusion (p = 0.488), the 30-day reoperation rates (p = 0.969), or mortality (p = 0.417). After adjusted propensity score analysis, postoperative morbidity (p = 0.833) and mortality (p = 0.568) were comparable in patients undergoing laparoscopic and open surgery.

CONCLUSIONS

On a national scale, laparoscopic emergent colon resections are being performed in a small number of patients, who have favorable co-morbidity characteristics and improved postoperative outcomes. Laparoscopic emergent colon resection with primary anastomosis has postoperative morbidity and mortality rates comparable to those seen with the open approach, and it reduces the total and postoperative length of hospital stay.

Prolonged preoperative hospitalization correlates with worse outcomes after colectomy for acute fulminant ulcerative colitis

BACKGROUND

Although total abdominal colectomy has long been considered definitive treatment for fulminant ulcerative colitis refractory to medical management, the optimal timing of surgery remains controversial. Early surgical intervention may be beneficial to patients with acute ulcerative colitis. Our goal was to compare outcomes after colectomy for fulminant ulcerative colitis and to identify preoperative factors that are predictive of poor outcome.

METHODS

The charts of 107 patients treated by total abdominal colectomy with ileostomy for fulminant ulcerative colitis between 2004 and 2009 were retrospectively reviewed. Twenty-nine patients sustained a major postoperative complication; 78 patients recovered uneventfully. Perioperative statistics, 30-day readmission/reoperation rates, and perioperative morbidity and mortality were compared using the Student t and Fisher exact tests and χ(2) analysis where appropriate.

RESULTS

White blood cell count at admission was significantly higher among patients who developed postoperative complications, but there were no differences in patient characteristics, other acute illness measures, or disease extent. Univariate analysis revealed that patients who developed postoperative complications underwent colectomy significantly later (3.6 vs 7.4 days; P = .01) than those who recovered uneventfully. Laparoscopic colectomy took significantly longer than open surgery, but did not affect postoperative morbidity. Multivariate analysis revealed duration of preoperative medical treatment to be the only significant predictor of increased risk of postoperative morbidity. Follow-up data revealed that similar percentages of patients in both groups eventually underwent ileal pouch anal anastomosis (IPAA; 68% vs 77%; P = .5).

CONCLUSION

Prolonged duration of preoperative medical treatment correlates with poor postoperative outcomes after total abdominal colectomy for fulminant ulcerative colitis. In addition, sustaining postoperative complications did not prevent patients from eventually undergoing IPAA.

Totally laparoscopic total proctocolectomy: a safe alternative to open surgery in inflammatory bowel disease

BACKGROUND

Inflammatory bowel disease (IBD) patients have a high incidence of wound and overall postoperative complications. A totally laparoscopic approach could potentially reduce these risks. We adopted totally laparoscopic total proctocolectomy (TL-TPC) using the perineal wound for extraction as the procedure of choice in IBD patients who are not candidates for a restorative procedure. This study looks at the TL-TPC results and compares them with our open cohort.

METHODS

Prospectively collected data from 52 consecutive patients undergoing TL-TPC from 2002 to 2010 were compared to 31 contemporary patients undergoing open TPC.

RESULTS

Demographics and patient characteristics including body mass index were similar. Mean operative times were 340 ± 7 minutes for TL-TPC and 337 ± 9 minutes for open TPC (P = 0.91). Intraoperative blood loss was 228 ± 2 mL for TL-TPC and 484 ± 3 mL for open TPC (P < 0.001). Return of bowel function measured as an ileostomy output >100 mL per 8 hours occurred at 2.7 ± 2.8 days for TL-TPC versus 3.3 ± 1.8 days for open TPC (P = 0.025). The length of stay was 8.4 ± 5.0 days for TL-TPC versus 9.2 ± 3.2 days for open TPC (P = 0.05). The overall complication rate was 43% for TL-TPC versus 65% for open TPC (P = 0.07). Postoperative abdominal wound infections and parastomal hernias occurred in 23% and 10% of open TPC patients, respectively, versus zero (P = 0.001) and 6% (P = 0.67) for TL-TPC.

CONCLUSIONS

TL-TPC is therefore considered a safe alternative to open surgery for selected IBD patients not candidates for a restorative procedure.

Laparoscopic surgery for ulcerative colitis

Laparoscopic techniques have become increasingly used in the treatment of ulcerative colitis: in experienced hands, they are safe and feasible. Recovery advantages have not been consistently demonstrated and functional results have been comparable to open surgery. Other possible benefits and costs issues have also been inconsistent. Further investigation on the role of laparoscopic surgery for ulcerative colitis with larger populations and longer follow-up with a focus on recovery parameters, quality of life, and costs are needed.

Treatment of hospitalized adult patients with severe ulcerative colitis: Toronto consensus statements

OBJECTIVES

The objective of this study was to provide updated explicit and relevant consensus statements for clinicians to refer to when managing hospitalized adult patients with acute severe ulcerative colitis (UC).

METHODS

The Canadian Association of Gastroenterology consensus group of 23 voting participants developed a series of recommendation statements that addressed pertinent clinical questions. An iterative voting and feedback process was used to do this in conjunction with systematic literature reviews. These statements were brought to a formal consensus meeting held in Toronto, Ontario (March 2010), when each statement was discussed, reformulated, voted upon, and subsequently revised until group consensus (at least 80% agreement) was obtained. The modified GRADE (Grading of Recommendations Assessment, Development, and Evaluation) criteria were used to rate the strength of recommendations and the quality of evidence.

RESULTS

As a result of the iterative process, consensus was reached on 21 statements addressing four themes (General considerations and nutritional issues, Steroid use and predictors of steroid failure, Cyclosporine and infliximab, and Surgical issues).

CONCLUSIONS

Key recommendations for the treatment of hospitalized patients with severe UC include early escalation to second-line medical therapy with either infliximab or cyclosporine in individuals in whom parenteral steroids have failed after 72 h. These agents should be used in experienced centers where appropriate support is available. Sequential therapy with cyclosporine and infliximab is not recommended. Surgery is an option when first-line steroid therapy fails, and is indicated when second-line medical therapy fails and/or when complications arise during the hospitalization.

Laparoscopic total colectomy: Does the indication influence the outcome?

AIM: To assess and compare outcomes of laparoscopic total colectomy performed for a variety of indications.

METHODS: Sixty six patients underwent laparoscopic total colectomy for inflammatory bowel disease (IBD) (13) and other diseases (53). Data on demographics, pre- and post-operative outcomes were collected prospectively.

RESULTS: Mean operative time was 4.5 h. Conversion rate was 13.6%. Total colectomy performed for IBD was associated with a significantly higher anastomotic leak rate (23.1% vs 1.9%, P < 0.05). On univariate analysis, hand sewn anastomosis and treatment with more than 20 mg of prednisolone for at least 3 mo was associated with a higher anastomotic leak rate (P < 0.05). No significant difference was found in return of gut function and overall morbidity between disease groups.

CONCLUSION: Laparoscopic total colectomy is feasible and outcomes are equivalent whatever the indication, except for anastomotic leak rate which is higher for patients with IBD.

Incisionless Laparoscopic Total Proctocolectomy with Ileal J-Pouch Anal Anastomosis

Minimally invasive surgery continues to evolve. Recent innovations have included single-incision access, robotic technology, and natural orifice dissection and/or specimen extraction. Many argue that there is minimal patient benefit to these advanced techniques. We report 39 patients undergoing laparoscopic ileal J-pouch anal anastomosis surgery, 17 of whom did not have a separate specimen extraction incision (Group 1). The specimen for this group was extracted through the circular incision made for the ileostomy; the pouch was constructed extracorporeally and returned to the abdomen through the stoma site. For the remaining 22 patients, a suprapubic Pfannenstiel incision was made (Group 2). No hand-assistance was used for either group. Group 1 showed a 45-minute reduction in operative time, a 1-day reduction in hospital stay, and a reduction in complications. Although these differences are modest, it shows that minimally invasive surgery is an evolving process. Small modifications may translate into significant advantages.

Staged restorative proctocolectomy: laparoscopic or open completion proctectomy after laparoscopic subtotal colectomy? Surg Endosc. 2011;25:3294-3299. [PMID: 21533970 DOI: 10.1007/s00464-011-1707-0]

BACKGROUND

The aim of this study was to compare outcomes of laparoscopic and open completion proctectomy (CP) and ileal-pouch anal anastomosis (IPAA) after a previous laparoscopic subtotal colectomy (STC).

METHODS

From a prospectively maintained ileal pouch database, outcomes for patients who underwent laparoscopic CP after laparoscopic STC (LSTC-LCP group) for ulcerative or indeterminate colitis were compared to those for patients who underwent open CP (LSTC-OCP group). A control group of open CP after open STC (OSTC-OCP group) was case-matched to LSTC-OCP at a ratio of 1:2 for age at surgery, gender, body mass index (BMI), year of operation, and American Society of Anesthesiologists (ASA) classification. Demographics, perioperative data, and pouch function were compared. Quality of life was evaluated using the Cleveland Global Quality of Life Scale (CGQL).

RESULTS

Between 1997 and 2009, 47 patients underwent LSTC followed by LCP (LSTC-LCP), and 48 patients underwent OCP after LSTC (LSTC-OCP); the latter group was matched to 96 open-open patients (OSTC-OCP). There were no significant differences in demographic and preoperative data among the three groups, except that the OSTC-OCP group patients were younger. Postoperative morbidity, pouch function, and CGQL were similar. LSTC-LCP patients had lower estimated blood loss (EBL) (p < 0.001), less commonly described intraoperative adhesiolysis (p < 0.001), reduced length of hospital stay (LOS) (p = 0.002) but longer operating time (p = 0.001) at CP/IPAA when compared with open-open patients. For patients with previous LSTC, LCP was associated with less commonly described intraoperative adhesiolysis (p = 0.003) and shorter LOS (p = 0.003) than OCP but a longer operating time (p = 0.036).

CONCLUSIONS

Laparoscopic CP and IPAA can be performed with safety comparable to that of open surgery after previous laparoscopic STC. The laparoscopic approach is associated with advantages including reduced intraoperative blood loss and earlier recovery as demonstrated by shorter length of hospital stay.

Laparoscopic total/subtotal colectomy for colorectal diseases: an analysis of 24 cases

AIM: To evaluate the efficacy and safety of laparoscopic total/subtotal colectomy in the management of familial adenomatous polyposis (FAP), ulcerative colitis (UC) and slow transit constipation (STC).

METHODS: The clinical data for 24 patients (including four FAP patients, seven UC patients, and 13 STC patients) who underwent laparoscopic total/subtotal colectomy at our hospital were analyzed retrospectively. FAP patients and UC patients were treated by laparoscopic total colectomy, while STC patients received laparoscopic subtotal colectomy.

RESULTS: The surgery was successful in all the 24 patients. Mean operative duration was 280 min ± 60 min, and mean intraoperative blood loss was 220 mL ± 80 mL. The function of the stomach and intestine was restored in 1-3 d. Complications, such as hemorrhage, infections, intestinal fistula and intestinal obstruction, did not occur. Improved quality of life was achieved in all the patients, and no recurrence occurred.

CONCLUSION: Laparoscopic total/subtotal colectomy is effective and safe in the management of colorectal diseases.

Laparoscopic colectomy and restorative proctocolectomy for familial adenomatous polyposis

BACKGROUND

Familial adenomatous polyposis (FAP) is a dominantly inherited syndrome. Risk of cancer begins to increase after age 20 years if not treated. The purpose of this study was to evaluate the feasibility and short- and long-term outcomes after laparoscopic prophylactic surgery for FAP.

METHODS

Fifty-five patients with FAP were identified through the Hereditary Colorectal Tumor Registry from 2003 to 2009. Patients with laparoscopic total colectomy (TC)/IRA or proctocolectomy (TPC)/ileal pouch-anal anastomosis IPAA were included. Patients with previous colon or abdominal major surgery, malignancy, and desmoids before surgery were excluded. Main outcomes were: 30 days anastomotic leak and pouch failure; long-term desmoids and malignant recurrence.

RESULTS

Of the 55 patients, 32 were men, median age was 28 years, and mean body mass index was 23. Median follow-up time was 36 (range, 5-77) months. Forty-four patients had laparoscopic TC/IRA and ten had laparoscopic TPC/IPAA. One patient was converted to open surgery and received an open TPC/IPAA. Incision length was 7 (range, 5-14) cm. Anastomotic leak was 3 (5.4%: 2 laparoscopic and 1 open), and pouch failure was 0. Median postsurgical length of stay was 7 (range, 4-24) days. Desmoids occurred in three patients (5.4%), and there was no malignant recurrence within the follow-up period. Pathology revealed severe dysplasia in ten patients and adenocarcinoma in nine (8 laparoscopic and 1 open). Long-term small-bowel obstruction was 2 (3.6%). One mortality due to liver metastases occurred at 24 months.

CONCLUSIONS

Laparoscopic prophylactic treatment of FAP appears to be safe and feasible and may be an appealing alternative to open surgery. If the goal of prophylactic FAP surgery is to avoid cancer occurrence, laparoscopic surgery could be an important advancement.

Comparative analysis between laparoscopic (UCL) and open (UCO) technique for the treatment of ulcerative colitis in pediatric patients

PURPOSE

The aim of this study is to compare laparoscopic with open approach in the surgical treatment of ulcerative colitis (UC) MATERIAL AND METHODS: Between July 1991 and August 2009, 32 consecutive unselective patients with UC received surgical treatment. The population analyzed was divided into three groups: subtotal colectomy + ileocolostomy (Group 1), proctectomy + ileoanal pouch (Group 2), one-step proctocolectomy + ileoanal pouch (Group 3). We analyzed the mean operating time, postoperative oral intake, use of opiates, the length of hospital stay and postoperative morbidity in each group. Open and laparoscopic approaches were compared in each group retrospectively.

RESULTS

In Group 1 the mean operating time was longer for the laparoscopic group (301 vs. 197 min; p < 0.01). The length of postoperative stay was longer for the open group (8 vs. 19 days; p < 0.05) and the oral intake started earlier in the laparoscopic group (3, 5 vs. 6, 2 days; p = 0.05). No significant difference was found in the use of opiates (p = ns). A total of four major complications occurred in the laparoscopic group and another four in the open approach. In Group 2, there was no significant difference in operating time between laparoscopic and open approach. The laparoscopic group started earlier to tolerate (p < 0.05) and there were significantly differences in the use of narcotics and hospital stay (p < 0.05). General complications were related to the pouch. In Group 3 the mean operating time was longer for the laparoscopic group (470 vs. 330 min p < 0.05). Patients with a laparoscopic approach had a shorter hospital stay (5, 6 vs. 10 days; p < 0.05) and postoperative narcotic use and they started earlier to tolerate (p < 0.05). One major complication was presented in the laparoscopic procedure and two in the open approach.

CONCLUSIONS

Of the 165 patients with UC in our hospital, 32 underwent surgery. The laparoscopic approach seems feasible and safe. A single staged approach (Group 1 + Group 2) remains the most reasonable choice for most patients. One-step approach was done only in selected cases (Group 3). The advantages of laparoscopy, such as improved cosmetic aspects, shorter postoperative ileus and hospital stay, were observed in the laparoscopic colectomy, proctectomy and ileoanal pouch in our study.

The role of laparoscopic surgery for ulcerative colitis: systematic review with meta-analysis

PURPOSE

Crohn's disease is established in laparoscopic surgery due to partial bowel dissection and low postoperative complication rate. However, laparoscopic surgery for ulcerative colitis remains further discussed even if the trend of minimally invasive technique exists. This study is to figure out how laparoscopic surgery works for ulcerative colitis.

METHODS

Sixteen controlled trials were identified through the search strategy mentioned below. There was only one prospective randomized study among the studies selected. A meta-analysis pooled the outcome effects of laparoscopic surgery and open surgery was performed. Fixed effect model or random effect model was respectively used depending on the heterogeneity test of trials.

RESULTS

Postoperative fasting time and postoperative hospital stay were shorter in laparoscopic surgery for ulcerative colitis (-1.37 [-2.15, -0.58], -3.22 [-4.20, -2.24], respectively, P < 0.05). Overall complication rate was higher in open surgery, compared with laparoscopic surgery (54.8% versus 39.3%, P = 0.004). However, duration of laparoscopic surgery for ulcerative colitis was extended compared with open surgery (weighted mean difference 69.29 min, P = 0.04). As to recovery of bowel function, peritoneal abscess, anastomotic leakage, postoperative bowel obstruction, wound infection, blood loss, and mortality, laparoscopic surgery did not show any superiority over open surgery. Re-operation rate was almost even (5.2% versus 7.3%). The whole conversion to open surgery was 4.2%.

CONCLUSIONS

Laparoscopic surgery for ulcerative colitis was at least as safe as open surgery, even better in postoperative fasting time, postoperative hospital stay, and overall complication rate. However, clinical value of laparoscopic surgery for ulcerative colitis needed further evaluation with more well-designed and long-term follow-up studies.

A prospective, randomized, single-blind comparison of laparoscopic vs open sigmoid colectomy for diverticulitis. Ann Surg. 2010;252:3-8. [PMID: 20505508 DOI: 10.1097/sla.0b013e3181dbb5a5]

OBJECTIVE

The aim of this study was to compare open and laparoscopic sigmoid resection for diverticulitis with the patient and the nursing staff blinded to the surgical approach.

METHODS

A total of 113 patients scheduled for an elective sigmoidectomy were randomized to receive either a conventional open (54 patients) or a laparoscopic (59 patients) approach. Postoperatively, an opaque wound dressing was applied and left in place for 4 days, and patients from both groups were managed similarly. The primary endpoints for analysis were (1) postoperative pain; (2) duration of postoperative ileus; and (3) duration of hospital stay (ClinicalTrials.gov, number NCT 00453830).

RESULTS

The median duration of procedure was 165 minutes (range, 90-285) in the laparoscopy group and 110 minutes (range, 70-210) in the open group (P < 0.0001). The median delay between surgery and first bowel movement was 76 (range, 31-163) hours in the laparoscopy group versus 105 (range, 53-175) hours in the open group (P < 0.0001). The median score for maximal pain (assessed by a visual analog scale) was 4 (range, 1-10) in the laparoscopy group and 5 (range, 1-10) in the open group (P = 0.05). Finally, the median duration of hospital stay was 5 days (range, 4-69) in the laparoscopy group versus 7 days (range, 5-17) in the open group (P < 0.0001).

CONCLUSION

Laparoscopic sigmoid resection is associated with a 30% reduction in duration of postoperative ileus and hospital stay; by comparison, benefits in terms of postoperative pain appear less impressive, when the patient is blinded to the surgical technique.

Laparoscopy for inflammatory bowel disease: pushing the envelope

Despite the slower learning curve of laparoscopic colectomy and the lack of prospective randomized trials, laparoscopic procedures have repeatedly demonstrated a shortened length of stay, reduction in postoperative ileus, and earlier resumption of diet. However, laparoscopy in inflammatory bowel disease has unique challenges that must be overcome. For the patient with uncomplicated terminal ileal Crohn's disease, there are definite reproducible advantages to a minimally invasive approach. As surgeons gain experience, more complex cases may be attempted laparoscopically with a low threshold to alternate the approach if difficulties are encountered. We will continue to "push the envelope" in patients with complex Crohn's disease to allow more to be done in complex cases. For the patient with Crohn's colitis and ulcerative colitis, the role of a minimally invasive approach is less well defined. In experienced hands, a laparoscopic total colectomy can be performed safely and offers the patient all the advantages seen with laparoscopic segmental resection. Outcomes are likely to improve with better training, techniques, and equipment. As the field of minimally invasive surgery continues to expand, what is being "pushed" today will be routine in the future.

Delayed surgery for acute severe colitis is associated with increased risk of postoperative complications

BACKGROUND

This study determined the long-term outcome after colectomy for acute severe ulcerative colitis (ASUC) and assessed whether the duration of in-hospital medical therapy is related to postoperative outcome.

METHODS

All patients who underwent urgent colectomy and ileostomy for ASUC between 1994 and 2000 were identified from a prospective database. Patient details, preoperative therapy and complications to last follow-up were recorded.

RESULTS

Eighty patients were identified, who were treated with intravenous steroids for a median of 6 (range 1-22) days before surgery. Twenty-three (29 per cent) also received intravenous ciclosporin. There were 23 complications in 22 patients in the initial postoperative period. Sixty-eight patients underwent further planned surgery, including restorative ileal pouch-anal anastomosis in 57. During a median follow-up of 5.4 (range 0.5-9.0) years, 48 patients (60 per cent) developed at least one complication. Patients with a major complication at any time during follow-up had a significantly longer duration of medical therapy before colectomy than patients with no major complications (median 8 versus 5 days; P = 0.036).

CONCLUSION

Delayed surgery for patients with ASUC who do not respond to medical therapy is associated with an increased risk of postoperative complications.

[Therapy of refractory proctocolitis and Crohn's disease. Incisionless laparoscopic proctocolectomy with a Brooke ileostomy]

BACKGROUND

Laparoscopic colorectal surgery is nowadays also widely used in surgery of inflammatory bowel disease. With the correct indications laparoscopic surgery is an attractive cosmetic alternative for the predominantly juvenile patients. Refractory fistulizing Crohn's proctocolitis is a very severe disease with a maximal limitation on the quality of life. Proctocolectomy with a Brooke ileostomy represents a very effective option for these patients. The laparoscopic technique can at least spare the patients a salvage laparotomy incision. We report about our preliminary experiences

PATIENTS AND METHOD

A total of 8 patients (mean age 25 years, range 19 Background 31 years, female:male ratio 5:3) were operated on. The mean preoperative time course of the disease was 28 months (range 12 Background 156 months). All patients had received long-term prednisolone therapy of >15mg, 2 patients received azathioprine medication, 2 underwent anti TNF-alpha therapy and 6 received 5-aminosalicylic acid (5-ASA). The mean preoperative BMI was 19 (range 15 Background 21). All patients suffered from Crohn's pancolitis with anorectal fistulas. Laparoscopic proctocolectomy was performed using 4 trocars place in a semicircular fashion. The resected tissue was salvaged transanally and the Brooke ileostomy was drained via the right lateral trocar. The terminal exit of the rectum occurred transanally with preservation of the pelvic floor and the anal sphincter and the anal fistulas were separated. The small pelvis was filled by a transanally fixed omentum.

RESULTS

The median time for surgery was 236.5 mins (range 220-330 mins). A complication of postoperative paralysis of the bowel occurred in two patients and 4 patients could be discharged problem-free according to the fast-track concept. Cosmetic results were excellent in all cases. Perianal and perirectal manifestations healed completely after a median of 4 weeks.

CONCLUSIONS

Incisionless proctocolectomy represents a good and realizable alternative to open surgery. The main advantages are excellent cosmetic results and a better preservation of the external integrity of the abdomen.

Laparoscopic colon surgery: does operative time matter?

PURPOSE

The purpose was to determine if the perioperative benefits associated with laparoscopic colectomies are maintained as operative time increases.

METHODS

A retrospective review was performed of a database that was prospectively collected from April 1991 to May 2005. Since operative time distributions were different, patients were divided into three groups: laparoscopic right colectomy or ileocecal resection, sigmoid resection, and total abdominal colectomy. The following outcomes were assessed: intraoperative and postoperative complications, days to surgical diet, length of stay, 30-day mortality, and the presence of a learning curve.

RESULTS

Following exclusions, there were 231 right colon and ileocecal resections, 210 sigmoid colectomies, and 46 total abdominal colectomies. With increasing operative time in both right/ileocecal and sigmoid resections, logistic regression demonstrated no significant association between intraoperative and postoperative complications, days to surgical diet, or length of stay. Weight was significantly correlated with increasing operative time in the right/ileocecal and sigmoid resection groups. In the total abdominal colectomy group, significant relationships between increased operative time and postoperative complications (P = 0.04), days to surgical diet (P = 0.02), and hospital stay (P = 0.03) were found. An operative time cut-point was determined in the total abdominal colectomy group. Patients with operative times >270 minutes were more likely to have postoperative complications (P = 0.024), longer ileus (five vs. three median days to surgical diet, P = 0.003), and longer length of stay (seven vs. five days, P = 0.04). This increased risk remained significant after adjusting for weight and diagnosis. No significant learning curve was identified.

CONCLUSION

Increasing operative time does not appear to adversely affect perioperative outcomes in segmental colectomies. Total abdominal colectomies lasting more than 270 minutes were associated with increased postoperative complications, days to surgical diet, and length of stay.

Hand-assisted versus conventional laparoscopic restorative proctocolectomy for ulcerative colitis. Surg Laparosc Endosc Percutan Tech. 2009;19:52-56. [PMID: 19238068 DOI: 10.1097/sle.0b013e31818a93d6]

AIM

In a few comparative and randomized studies, hand-assisted laparoscopic restorative proctocolectomy (HALS-RP) maintained the advantages of a minimally invasive approach with some potential benefits. However, the role of HALS-RP has not been defined. The aim of this study was to evaluate the effectiveness of HALS-RP compared with a conventional laparoscopic restorative proctocolectomy (LAP-RP) in patients with ulcerative colitis.

METHODS

A retrospective study was conducted using a prospectively maintained database to compare a consecutive series of 30 patients who underwent HALS-RP from June 2004 to September 2007 with 40 patients who underwent LAP-RP from October 1994 to June 2004 in our institution. Patient characteristics, perioperative parameters, and the surgical outcomes were assessed. Mann-Whitney U and Fisher exact tests were used for statistical analysis.

RESULTS

Both groups were well matched with no differences in sex, body mass index, periods from diagnosis, American Society of Anesthesiologists score, performance status, preoperative blood chemistry or steroid, and cyclosporine usage. The median operative time was significantly shorter for HALS-RP [356 (range: 176 to 590) min] than for LAP-RP [505 (range: 360 to 785) min; P<0.001]. The median length of incision was significantly longer for HALS-RP [8 (range: 7.5 to 8) cm] than for LAP-RP [5.5 (range: 5 to 8) cm]. The estimated blood loss and the length of hospital stay were similar between the 2 groups. The incidence of postoperative complications including anastomotic leakage did not differ between the 2 groups (P=0.437).

CONCLUSIONS

HALS-RP significantly reduced the operative time compared with the conventional LAP-RP, while retaining the acceptable morbidity rates and recovery benefits associated with minimally invasive surgery. HALS-RP is likely to replace a conventional laparoscopic approach for this technically challenging procedure.

Minimally invasive total proctocolectomy with Brooke ileostomy for ulcerative colitis

BACKGROUND

Total proctocolectomy with Brooke ileostomy remains the optimal surgical procedure for select ulcerative colitis patients. However, few studies describe outcomes of minimally invasive total proctocolectomy with Brooke ileostomy. Our aim was to describe the safety and feasibility of these procedures by examining short-term (30-day) outcomes.

METHODS

Using a prospective database, we identified a cohort of patients who underwent laparoscopic total proctocolectomy with Brooke ileostomy at our institution from 2000-2007. Results are reported as median (range) or frequency (proportion).

RESULTS

Forty-four patients were included; age 65 years (54-73), 24 were male (55%), body mass index was 26.5 (22.1-30.2) kg/m(2). Colitis duration was 66 months (24-240), and 40% had prior surgery. The indication for surgery was refractory colitis (82%) and neoplasia (18%). Factors influencing choice of total proctocolectomy with permanent ileostomy were advanced age in 18 (41%), lifestyle in 13 (30%), medical comorbidities in 11 (25%), fecal incontinence in 10 (23%), oncologic reasons in 3 (6.8%), and obesity in 3 (6.8%). Twenty-three (52%) operations were hand-assisted laparoscopic surgery, 13 (30%) were laparoscopic-assisted, and 8 (18%) were "laparoscopic-incisionless" with transanal specimen extraction. Two laparoscopic-assisted cases (4.6%) were converted. Operative time was 329 (272-402) minutes, and length of stay 5 (4-6) days. Major post-operative complications occurred in 4 (9%); there were no perioperative mortalities.

CONCLUSIONS

Minimally invasive total proctocolectomy with Brooke ileostomy is a safe, feasible option for the surgical treatment of chronic ulcerative colitis, and is the procedure of choice for select patients.

The evolution of prophylactic colorectal surgery for familial adenomatous polyposis

INTRODUCTION

Over the past 50 years, prophylactic colorectal surgery for patients with familial adenomatous polyposis has evolved as new technologies and ideas have emerged. The aim of this study was to review all the index surgeries for familial adenomatous polyposis performed at our institution to assess the changes in surgical techniques.

METHODS

All index abdominal surgeries for polyposis from 1950 to 2007 were identified through the Polyposis Registry Database. We assigned the patients to prepouch (before 1983), pouch (after 1983), and laparoscopic (after 1991) eras, and analyzed the changes in prophylactic surgery.

RESULTS

Four hundred twenty-four patients were included; 51% were male. Median age at surgery was 26 (range, 9-66) years. In the prepouch era, 97% (66 of 68) of all surgeries and 100% of restorative surgeries were ileorectal anastomosis. After 1983, 70% (54 of 77) of patients with a severe phenotype had an ileal pouch-anal anastomosis. After 1991, 110 operations (43%) were laparoscopic (88 ileorectal and 22 ileal pouch-anal anastomosis).

CONCLUSION

Colon surgery for familial adenomatous polyposis has evolved as advances in surgical technique have created more options to reduce the risk of cancer. Current strategy uses polyposis severity and distribution to decide on the surgical option, and laparoscopy to minimize morbidity.

Hand-assisted laparoscopic vs. open subtotal colectomy for severe ulcerative colitis

PURPOSE

This study aimed to assess the feasibility and safety of undergoing emergency subtotal colectomy with hand-assisted laparoscopic surgery in patients with severe ulcerative colitis.

METHODS

We reviewed the medical records of 60 patients who underwent emergency subtotal colectomy with hand-assisted laparoscopic technique (30 cases) or open technique (30 cases) for severe ulcerative colitis.

RESULTS

No intraoperative complications occurred in either group. One patient in the laparoscopic group required conversion to open surgery. The median operative time was significantly longer in the laparoscopic group (242 vs. 191 minutes; P < 0.001). The rate of early postoperative complications in the laparoscopic group was significantly less than that in the open group (37 percent vs. 63 percent; P = 0.041). In the open group, four patients required relaparotomy because of peritoneal abscess or strangulation ileus, whereas no patient required relaparotomy in the laparoscopic group (P = 0.040). In the laparoscopic group, the median duration of postoperative food prohibition was significantly shorter (4.8 vs. 5.9 days; P = 0.007), and the median length of hospital stay was significantly shorter (23.0 vs. 33.0 days; P = 0.001).

CONCLUSIONS

Although the operative time was elongated in the laparoscopic group, intraoperative safety and postoperative recovery were satisfactory. For severe ulcerative colitis, hand-assisted laparoscopic surgery can be an alternative to conventional open surgery.

Colectomy in patients with acute colitis: a systematic review

BACKGROUND

For patients with acute colitis, the decision when and how to operate is difficult in most cases. It was the aim of this systematic review to analyze early mortality and morbidity of colectomy for severe acute colitis in order to identify opportunities to improve perioperative treatment and outcome.

METHODS

A systematic review of the available literature in the Medline and PubMed databases from 1975 to 2007 was performed. All articles were assessed methodologically; the articles of poor methodological quality were excluded. Articles on laparoscopic colectomy for acute colitis were analyzed separately.

RESULTS

In total, 29 studies met the criteria for the systematic review, describing a total of 2,714 patients, 1,257 of whom were operated on in an acute setting, i.e., urgent or emergency colectomy. Reported in-hospital mortality was 8.0%; the 30-day mortality was 5.2%. Morbidity was 50.8%. The majority of complications were of infectious and thromboembolic nature. Over the last three decades, there was a shift in indications from toxic megacolon, from 71.1% in 1975-1984 to 21.6% in 1995-2005, to severe acute colitis not responding to conservative treatment, from 16.5% in 1975-1984 to 58.1% in 1995-2007. Mortality decreased from 10.0% to 1.8%. Morbidity remained high, exceeding 40% in the last decade. Mortality after laparoscopic surgery was 0.6%. Complication rate varies from 16-37%.

CONCLUSION

Colectomy for acute colitis is complicated by considerable morbidity. The incidence of adverse outcome has substantially decreased over the last three decades, but further improvements are still required. The retrospective nature of the included studies allows for a considerable degree of selection bias that limits robust and clinically sound conclusions about both conventional and laparoscopic surgery.

Minimally invasive subtotal colectomy and ileal pouch-anal anastomosis for fulminant ulcerative colitis: a reasonable approach?

PURPOSE

This study was designed to evaluate the safety, feasibility, and short-term outcomes of three-stage minimally invasive surgery for fulminant ulcerative colitis.

METHODS

Using a prospective database, we identified all patients with ulcerative colitis who underwent minimally invasive surgery for both subtotal colectomy and subsequent ileal pouch-anal anastomosis at our institution from 2000 to 2007. Demographics and short-term outcomes were retrospectively evaluated.

RESULTS

During seven years, 50 patients underwent minimally invasive subtotal colectomy for fulminant ulcerative colitis; 50 percent were male, with a median age of 34 years. All patients had refractory colitis: 96 percent were taking steroids, 76 percent were recently hospitalized, 59 percent had >/=5 kg weight loss, 57 percent had anemia that required transfusions, 30 percent were on biologic-based therapy, and 96 percent had >/=1 severe Truelove & Witts' criteria. Of these 50 procedures, 72 percent were performed by using laparoscopic-assisted and 28 percent with hand-assisted techniques. The conversion rate was 6 percent. Subsequently, minimally invasive completion proctectomy with ileal pouch-anal anastomosis was performed in 42 patients with a 2.3 percent conversion rate. Median length of stay after each procedure was four days. There was one anastomotic leak and no mortality.

CONCLUSIONS

A staged, minimally invasive approach for patients with fulminant ulcerative colitis is technically feasible, safe, and reasonable operative strategy, which yields short postoperative length of stay.

Open versus laparoscopic (assisted) ileo pouch anal anastomosis for ulcerative colitis and familial adenomatous polyposis

BACKGROUND

Restorative proctocolectomy with ileo pouch anal anastomosis (IPAA) is the main surgical treatment for patients with ulcerative colitis (UC) and familial adenomatous polyposis (FAP). With the advancements of minimal-invasive surgery this demanding operation is increasingly being performed laparoscopically. Therefore, the presumed benefits of the laparoscopic approach need to be systematically evaluated.

OBJECTIVES

To compare the beneficial and harmful effects of laparoscopic versus open IPAA for patients with UC and FAP.

SEARCH STRATEGY

We searched The Cochrane IBD/FBD Group Specialized Trial Register (April 2007), The Cochrane Library (Issue 1, 2007), MEDLINE (1990 to April 2007), EMBASE (1990 to April 2007), ISI Web of Knowledge (1990 to April 2007) and the web casts of the American Society of Colon and Rectal Surgeons (ASCRS) (up to 2006) for all trials comparing open versus laparoscopic IPAA.

SELECTION CRITERIA

All trials in patients with UC or FAP comparing any kind of laparoscopic IPAA versus open IPAA. No language limitations were applied.

DATA COLLECTION AND ANALYSIS

Two authors independently performed selection of trials and data extraction. The methodological quality of all included trials was evaluated to assess bias risk. Analysis of RCTs and non-RCTs was performed separately. Analyses were based on the intention-to-treat principle. Authors were requested additional information in case of missing data. Sensitivity and subgroup analyses were performed if appropriate.

MAIN RESULTS

Eleven trials included 607 patients of whom 253 (41%) in the laparoscopic IPAA group. Only one of the included trials was a randomised controlled trial. There were no significant differences in mortality or complications between the two groups. Reoperation and readmission rates were not significantly different. Operative time was significantly longer in the laparoscopic group both in the RCT and meta-analysis of non-RCTs (weighted mean difference (WMD) 91 minutes; 95% Confidence Interval (CI) 53 to 130). There were no significant differences between the two groups regarding postoperative recovery parameters. Total incision length was significantly shorter in the laparoscopic group, while two trials evaluating cosmesis found significantly higher cosmesis scores in the laparoscopic group. Other long-term outcomes were poorly reported.

AUTHORS' CONCLUSIONS

The laparoscopic IPAA is a feasible and safe procedure. Short-term advantages of the laparoscopic approach seem to be limited and their clinical significance is arguable. Large high-quality trials focusing on differences regarding specific postoperative complications, cosmesis, quality of life and costs are needed.

Laparoscopic 3-step restorative proctocolectomy: comparative study with open approach in 45 patients. Surg Laparosc Endosc Percutan Tech. 2008;18:357-362. [PMID: 18716534 DOI: 10.1097/sle.0b013e3181772d75]

BACKGROUND

To compare the results of a total laparoscopic versus open approach 3-time ileal pouch anal anastomosis (IPAA) for patients with acute or severe colitis complicating inflammatory bowel disease.

METHODS

Consecutive subtotal colectomy was followed by IPAA then by stoma closure. Between 2000 and 2006, 23 consecutive patients, operated through a total laparoscopic approach were well matched with 22 patients operated by open approach.

RESULTS

Overall major complications rate was lower after laparoscopic than after open approach (5/23 vs. 9/22; NS). Mean hospital stay for the 3 consecutive procedures was significantly reduced after laparoscopic versus open approach (27+/-7 d vs. 39+/-27 d; P<0.05).

CONCLUSIONS

Our case-control study suggests that, in experienced centers, a total laparoscopic approach can be viewed as a viable alternative to conventional open 3-step IPAA for the treatment of acute or severe colitis complicating inflammatory bowel disease.

Laparoscopic vs. open total abdominal colectomy for severe colitis: impact on recovery and subsequent completion restorative proctectomy

PURPOSE

This study was designed to compare short-term outcomes of laparoscopic vs. open total abdominal colectomy and end ileostomy for severe ulcerative colitis and to evaluate the impact of the initial surgical approach on subsequent operations for three-stage restorative proctocolectomy.

METHODS

Perioperative demographic and outcome data for patients with severe ulcerative colitis who underwent laparoscopic (n = 37) or open (n = 41) total abdominal colectomy at the initial stage of a three-stage restorative proctocolectomy were compared. Each stage was analyzed independently by using two-tailed t-tests and analysis of covariance.

RESULTS

Patients who underwent laparoscopic total abdominal colectomy had higher serum albumin (P = 0.0003), less inpatient narcotic usage (P = 0.0143), faster return of bowel function (P = 0.0001), and shorter length of stay (P = 0.039). There were no differences in perioperative parameters for the restorative proctectomy and ileostomy closure. The laparoscopic total abdominal colectomy patients underwent subsequent restorative proctectomy 49 days sooner (P = 0.0044) and ileostomy closure 17 days sooner (P = 0.00003) than the open total abdominal colectomy patients.

CONCLUSIONS

Laparoscopic abdominal colectomy for severe ulcerative colitis in selected patients is safe and is associated with short-term benefits that may lead to faster recovery and progression to completion of restorative proctocolectomy.

Sexual function, body image, and quality of life after laparoscopic and open ileal pouch-anal anastomosis

PURPOSE

This study was designed to compare self-reported sexual function, body image, and quality of life outcomes among ulcerative colitis patients undergoing laparoscopic or open ileal pouch-anal anastomosis.

METHODS

Between 1978 and 2004, 100 laparoscopic and 189 open operations were performed in patients who were identified from a previously published cohort. Patients were surveyed one year after operation to evaluate sexual function, body image, and quality of life.

RESULTS

A total of 125 of 289 patients (43 percent) returned completed surveys. There were no significant differences in terms of demographics, complications, or long-term functional outcomes between those who completed the surveys and those who did not. There were no clinical differences in results between laparoscopic and open patients using the three survey instruments. Orgasmic function scores were lower in men who underwent laparoscopic ileal pouch-anal anastomosis (P < 0.05) compared with open ileal pouch-anal anastomosis. Overall, sexual function scores were equal to or better than normal values for men but were lower in women. Finally, overall body image and quality of life scores were above the means published for the United States.

CONCLUSIONS

After ileal pouch-anal anastomosis, men and women reported excellent body image and high cosmetic and quality of life scores regardless of operative approach. Female sexual function was more adversely affected after ileal pouch-anal anastomosis than was male sexual function.

Laparoscopic-assisted proctocolectomy using complete intracorporeal dissection

PURPOSE

Although many studies have demonstrated good results using laparoscopic proctocolectomy in patients with ulcerative colitis (UC), most surgical procedures require at least one additional incision larger than 5 cm to complete the surgery. The aim of this study was to evaluate the use of laparoscopic proctocolectomy with ileoanal J pouch, with a complete intracorporeal dissection using a 4-5 cm right lower quadrant (RLQ) incision.

METHODS

Data were collected prospectively from all patients with UC that were subjected to a proctocolectomy with ileoanal J pouch between August 2003 and December 2006. The dissection was performed completely by laparoscopy using a medial-lateral approach for the colon and a total mesorectal excision for the rectum. Once the rectum was resected laparoscopically, a 4-5 cm incision in the RLQ was performed to resect the specimen and then an end or a loop ileostomy was implanted at the RLQ wound. The surgery was performed in two (proctocolectomy with ileoanal J pouch and loop ileostomy) or three steps (subtotal colectomy and end ileostomy with sigmoid fistula; proctectomy with ileoanal J pouch; and loop ileostomy).

RESULTS

A total of 47 surgical procedures were performed in 32 patients with a mean age of 34.5 +/- 15.7 years, of which 56% were male. The mean body mass index was 21 +/- 16 kg/m(2); 50% of patients underwent surgery in two steps and the other 50% in three steps. Surgery was converted in five (10.6%) cases due to megacolon in one case, narrow pelvis in two, and difficult rectal dissection in two; the overall morbidity rate was 14.9%. Two patients required reoperation and no mortality was registered. The mean operative time was 248 +/- 62 min; proctocolectomy 292 +/- 61 min, subtotal colectomy 203 +/- 43 min, and proctectomy 248 +/- 47 min. The mean hospital stay was 4.8 +/- 1.9 days, and the mean interval time to close loop ileostomies was 64 +/- 12 days.

CONCLUSIONS

A complete laparoscopic proctocolectomy dissection is feasible and safe for surgical treatment of UC.

Laparoscopic surgery for patients with Crohn's colitis: a case-matched study

INTRODUCTION

The purpose of this study was to compare short and long-term outcomes of laparoscopic colectomy with open colectomy in patients with Crohn's disease confined to the colon.

MATERIALS AND METHODS

We reviewed all patients undergoing laparoscopic colectomy for Crohn's disease at our institution between 1994 and 2005. Laparoscopic colectomies were matched to open colectomies by patient age, gender, American Society of Anesthesiologists score, type, and year of surgery. We excluded patients with concomitant small bowel disease.

RESULTS

Twenty-seven laparoscopic cases were matched with 27 open cases. There were seven conversions (26%). There was no mortality. Median operative times were significantly longer after laparoscopic colectomy (240 vs 150 min, P < 0.01), and estimated blood loss was comparable (325 vs 350 ml, P = 0.4). Postoperative complications were similar. Laparoscopic colectomies had shorter median length of stay (5 vs 6 days, P = 0.07) and median time to first bowel movement (3 vs 4 days, P = 0.4). When overall length of stay included 30-day readmissions, the difference in favor of laparoscopy became statistically significant (P = 0.02). Recurrent disease requiring surgery was decreased after laparoscopy, although median follow-up was significantly shorter.

CONCLUSION

Laparoscopic colectomy is a safe and acceptable option for patients with Crohn's colitis. Longer follow-up is needed to accurately establish recurrence rates.

Combination of hand-assisted and laparoscopic proctocolectomy (HALP): Technical aspects, learning curve and early postoperative results

BACKGROUND

Various techniques for laparoscopic proctocolectomy have been reported worldwide. We evaluated the technical aspects and early postoperative results of hand-assisted laparoscopic proctocolectomy (HALP) with construction of an ileal pouch-anal anastomosis through a Pfannenstiel incision.

PATIENTS AND METHODS

Between June 2004 and May 2006, 20 patients (median age 28 years) underwent combined HALP at our institution. Preoperative diagnosis included ulcerative colitis (n = 16), indeterminate colitis (n = 1), familial adenomatous polyposis (n = 2), and carcinoma of the rectum associated with ulcerative colitis (n = 1). All patients were under immunosuppressive therapy. Laparoscopic mobilisation of rectum, sigmoid and descending colon was performed first. Subsequently, hand-assisted laparoscopic mobilization of the transverse and ascending colon as well as creation of an ileal J-pouch were performed through a Pfannenstiel incision. Ileal pouch-anal anastomosis was completed by transrectal stapling device and protected by a loop ileostomy.

RESULTS

The ileal pouch-anal anastomosis could be achieved in 19 cases (95%). There was one conversion (5%) to open surgery with construction of an end-ileostomy. No intraoperative blood transfusions were necessary. The median operating time was 210 minutes (range 180 min to 330 min). It was longer for the first five procedures but then remained constant. Two patients (10%) developed anastomotic leakage, which could be treated conservatively. Mean length of hospital stay was 11 days (range 7-32 days).

CONCLUSIONS

Combined HALP with construction of an ileal J-pouch-anal anastomosis can be performed safely and effectively. The Pfannenstiel incision proved to be advantageous for hand-assisted mobilisation of the transverse colon. Additionally, it was useful for the specimen removal and the J-pouch construction. Our new technique not only proved to be safe, but also resulted in a shortened total operation-time after a learning curve of about five procedures.

Laparoscopic total colectomy: an evolutionary experience

PURPOSE

Laparoscopic total abdominal colectomy and total proctocolectomy are technically challenging operations. Advances in minimally invasive techniques, including sleeveless hand-assist devices, may influence performance of these procedures. This study was designed to evaluate the results of laparoscopic total colectomy and to compare the hand-assisted approach with straight laparoscopy.

METHODS

Sequential patients undergoing hand-assisted and straight laparoscopic total abdominal colectomy and total proctocolectomy from 1997 to 2004 were identified from a single institution prospective database involving four colorectal surgeons, of which three had limited laparoscopic experience. Patient characteristics, perioperative parameters, and outcomes were assessed.

RESULTS

A total of 130 patients were analyzed. Sixty-nine patients underwent total abdominal colectomy (hand-assisted 17 vs. straight laparoscopic 52), and 61 underwent total proctocolectomy (hand-assisted 28 vs. straight laparoscopic 33). For both total abdominal colectomy and total proctocolectomy, the hand-assisted and straight laparoscopic groups were well matched. Although no differences were observed in operative blood loss and intraoperative complications, hand assistance resulted in fewer overall conversions to open (1/45 (2.2 percent) vs. 6/85 (7.1 percent); P < 0.01), with no conversions in the total abdominal colectomy group (0 vs. 9.6 percent; P = 0.05). There was a trend toward reduced operative time with hand assistance, and nonlaparoscopic staff surgeons performed a greater proportion of the hand-assisted cases (22.2 vs. 10.6 percent; P < 0.05).

CONCLUSIONS

Laparoscopic total colectomy is technically feasible and safe. With a significant reduction in conversions and a greater proportion of cases performed by nonlaparoscopic surgeons, there was an evolutionary shift to a hand-assisted technique. A hand-assisted approach may be a useful alternative to a straight laparoscopic approach for this technically challenging operation.
