Early experience with laparoscopic ileal pouch-anal anastomosis for ulcerative colitis

Outcomes of Partial Versus Total Colectomy in Ulcerative Colitis: A Propensity Score-Matched Analysis

INTRODUCTION

Total abdominal colectomy (TAC) with ileostomy is the standard treatment for severe ulcerative colitis (UC). Partial colectomy (PC) with colostomy may present a less morbid treatment option.

METHODS

The 2012-19 ACS-NSQIP database was queried to assess 30-day outcomes among patients undergoing TAC versus PC for UC, utilizing propensity score matching (PSM) techniques to account for differences in disease severity, patient selection, and presentation acuity.

RESULTS

Before matching (n = 9888), patients undergoing PC were older, had more comorbidities, and experienced higher complication and 30-day mortality rates (P < 0.001). After matching (n = 1846), patients undergoing TAC experienced higher 30-day overall complications (41.9% versus 36.5%, P = 0.017) and serious complications (37.2% versus 31.5%, P = 0.011). Sensitivity analyses of older patients and those undergoing nonemergency surgery demonstrated higher overall rates of complications for patients receiving TAC. However, among patients undergoing emergency surgery only, no differences in complications were seen between the two surgical approaches.

CONCLUSIONS

PC with colostomy in the setting of ulcerative colitis has similar 30-day outcomes to TAC with ileostomy. PC may be an acceptable surgical alternative to TAC in select patients. Studies investigating longer-term outcomes are necessary to further investigate this option.

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.

Current management of intestinal bowel disease: the role of surgery

Inflammatory bowel disease (IBD) is a chronic affection, in which the two main phenotypical components are Crohn's disease and ulcerative colitis. In both diseases, medical treatment has the main role; in some phases of the natural history of IBD, surgery becomes an important therapeutic tool. The IBD represents a model of multidisciplinary management. Timing represents the key issue for proper management of IBD patients. For acute and severe IBD, the surgery can be a salvage procedure. Today, the laparoscopic approach plays an important role in armamentarium of the surgeon. Several articles compared the short- and long-term results between laparoscopic and open approaches in IBD. The aim of this review is to focus the role of surgery in IBD as well as the role of laparoscopic approach, and principally, the "state of the art" for surgical treatment, sometimes very challenging for surgeon, in all clinical features of IBD by a review of literature highlighted by the most recent international guidelines.

A systematic review and meta-analysis of laparoscopic vs open restorative proctocolectomy

AIM

The benefits of a laparoscopic approach to restorative proctocolectomy (RPC) are controversial. The aim of this meta-analysis was to compare the outcome following laparoscopic and open RPC, with particular attention to adverse events and long-term function.

METHOD

A systematic search of the MEDLINE, EMBASE and Ovid databases was performed for studies published until March 2012. The primary end-point was long-term function. Secondary end-points were intra-operative details, short-term postoperative outcome and postoperative adverse events. Weighted mean difference (WMD) and odds ratio (OR) were calculated using fixed/random effect meta-analytic techniques.

RESULTS

The final analysis included 27 comparative studies of 2428 patients, of whom 1097 (45.1%) underwent laparoscopic surgery. A laparoscopic approach was associated with a significantly longer operation time (WMD 70.1 min, P < 0.001), shorter length of hospital stay (WMD -1.00 day, P < 0.001), reduced intra-operative blood loss (WMD -89.10 ml, P < 0.001) and a lower incidence of wound infection (OR 0.60, P < 0.005). No significant differences were observed in the rate of pouch failure. Although there was no significant difference in the number of daily bowel movements (OR 0.04, P = 0.950), laparoscopic surgery led to fewer nocturnal bowel movements (WMD -1.14, P < 0.001) and reduced pad usage during the day (OR 0.22, P < 0.001) and night (OR 0.33, P < 0.001). The post hoc power to detect differences in adverse event rates ranged from 5% to 42%.

CONCLUSION

Laparoscopic and open approaches to RPC produced equivalent adverse event rates and long-term functional results. However, the present evidence is underpowered to detect true differences in adverse event rates.

A comparison of the quality of life of ulcerative colitis patients after IPAA vs ileostomy

BACKGROUND

Total proctocolectomy with IPAA is frequently considered the procedure of choice for surgical patients with ulcerative colitis, presumably owing to an expectation of improved quality of life in comparison with an ileostomy.

OBJECTIVE

The goal of our study was to determine whether long-term quality of life among patients with a pelvic pouch is better than those who chose a permanent stoma.

DESIGN

This investigation is a cross-sectional observational study using a prospective database.

SETTING

This study was conducted at an academic medical center.

PATIENTS

Consecutive patients who had undergone IPAA or a permanent ileostomy for ulcerative colitis by a single surgeon, presenting for their annual follow-up visit from July through September 2011, were offered participation in the study. A randomly chosen group of subjects who did not have scheduled appointments during the study period were sent a letter inviting them to participate in the study.

MAIN OUTCOME MEASURES

The primary outcome measures used were EQ-5D-3L, the Short Quality of Life in Inflammatory Bowel Disease questionnaire, the Cleveland Global Quality of Life instrument, the Fecal Incontinence Quality of Life scale, and the Stoma Quality of Life scale.

RESULTS

Thirty-five patients with a pelvic pouch and 24 ostomates were accrued and comprehensively studied. Global quality-of-life scores were virtually identical for the 2 groups. Patients with a pelvic pouch had better subscores in current quality of health and energy level, Fazio score, sexuality/body image, and work/social function.

LIMITATIONS

This study was limited by its small sample size, and some of our patients were enrolled through mailed surveys and, hence, nonresponse bias may be present. The follow-up time since surgery was longer in the pelvic pouch group than in the ileostomy group.

CONCLUSION

Informed patients with ulcerative colitis choosing an ileostomy have a health-related global quality of life very similar to patients with a pelvic pouch. Better outcomes in patients with an ileal pouch were most evident in the areas of sexuality/body image and work/social function.

Quality of life, health-related quality of life and health status in patients having restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis: a systematic review

AIM

There are numerous studies on quality of life (QoL), health-related quality of life (HRQoL), and health status (HS) in patients undergoing surgery for ulcerative colitis. A systematic review of published literature was conducted to establish the quality of these studies and to determine QoL, HRQoL, and HS in patients after ileal pouch-anal anastomosis for ulcerative colitis.

METHOD

All published studies describing QoL, HRQoL, and HS in adult patients in combination with ileal pouch-anal anastomosis for ulcerative colitis were reviewed systematically. No time or language limitations were applied. Relevance was established on the basis of three pre-specified selection criteria: 1) ileal pouch-anal anastomosis was performed for ulcerative colitis, 2) QoL, HRQoL, and HS were reported as outcome of the study and 3) studies reported a minimum follow-up after surgery for 12 months. Outcome variables were results of QoL, HRQoL, and HS, characteristics of the study population, pouch construction, duration of follow-up, and time of assessment in months before and after restorative surgery. Descriptive data synthesis was performed by tabulation displaying the methodological quality, study characteristics and conclusions on QoL, HRQoL, and HS measurements in the studies.

RESULTS

The review included 33 studies comprising 4790 patients. Three were graded to be of high quality, 23 of moderate quality and seven of low quality. All reported improved HS and the majority reported improved HRQoL. However, none of the studies reported on QoL.

CONCLUSION

The HRQoL and HS of patients with ulcerative colitis improved 12 months after restorative proctocolectomy with an ileal pouch-anal anastomosis and were indistinguishable from the HRQoL and HS of the normal healthy population.

Feasibility of laparoscopic restorative proctocolectomy without diverting stoma

AIM

Restorative proctocolectomy performed before the advent of laparoscopy had evolved to frequently omit a diverting stoma. Our aim was to assess the impact of a diverting stoma on postoperative outcomes following laparoscopic restorative proctocolectomy.

METHOD

Data on all patients undergoing a laparoscopic restorative proctocolectomy at our institution were prospectively collated in a database.

RESULTS

Between November 2004 and February 2010, 71 patients (38 females) underwent laparoscopic restorative proctocolectomy. Indications included familial adenomatous polyposis (n=34), ulcerative colitis (n=35), indeterminate colitis (n=1) and Lynch syndrome (n=1). Laparoscopic restorative proctocolectomy was performed as a one-stage procedure in 49 patients, and after a sub-total colectomy in 22. Seven patients in each group underwent the formation of a diverting stoma. Nine patients required conversion to open surgery. Sixteen patients experienced at least one postoperative complication. The postoperative morbidity was 29% (n=4/14) and 21% (n=12/21) in patients with and without a stoma (p=0.8), and the rate of fistula was 21% and 5%, respectively (p=0.08). Seven percent of patients with a stoma and 16% without stoma had an intra-abdominal collection (p=0.7). Nine patients required reoperation. The reoperation rate was not influenced by the presence or absence of a diverting stoma.

CONCLUSION

Laparoscopic restorative proctocolectomy can be performed safely without a diverting stoma in selected patients.

Recent results of laparoscopic surgery in inflammatory bowel disease

Inflammatory bowel diseases are an ideal indication for the laparoscopic surgical approach as they are basically benign diseases not requiring lymphadenectomy and extended mesenteric excision; well-established surgical procedures are available for the conventional approach. Inflammatory alterations and fragility of the bowel and mesentery, however, may demand a high level of laparoscopic experience. A broad spectrum of operations from the rather easy enterostomy formation for anal Crohn’s disease (CD) to restorative proctocolectomies for ulcerative colitis (UC) may be managed laparoscopically. The current evidence base for the use of laparoscopic techniques in the surgical therapy of inflammatory bowel diseases is presented. CD limited to the terminal ileum has become a common indication for laparoscopic surgical therapy. In severe anal CD, laparoscopic stoma formation is a standard procedure with low morbidity and short operative time. Studies comparing conventional and laparoscopic bowel resections, have found shorter times to first postoperative bowel movements and shorter hospital stays as well as lower complication rates in favour of the laparoscopic approach. Even complicated cases with previous surgery, abscess formation and enteric fistulas may be operated on laparoscopically with a low morbidity. In UC, restorative proctocolectomy is the standard procedure in elective surgery. The demanding laparoscopic approach is increasingly used, however, mainly in major centers; its feasibility has been proven in various studies. An increased body mass index and acute inflammation of the bowel may be relative contraindications. Short and long-term outcomes like quality of life seem to be equivalent for open and laparoscopic surgery. Multiple studies have proven that the laparoscopic approach to CD and UC is a safe and successful alternative for selected patients. The appropriate selection criteria are still under investigation. Technical considerations are playing an important role for the complexity of both diseases.

Mid-term functional outcome of laparoscopic restorative proctocolectomy: a prospective study of 40 consecutive cases

INTRODUCTION

This prospective study aimed to analyze the functional outcome after a two-stage laparoscopic total proctocolectomy with ileal pouch-anal anastomosis.

MATERIALS AND METHODS

From May 1999 to May 2008, 68 consecutive two-stage laparoscopic total proctocolectomies with ileal pouch-anal anastomosis were performed (ulcerative colitis: n = 61; familial adenomatous polyposis: n = 7). A covering ileostomy was used in all patients. Forty patients whose covering ileostomy had been closed for a minimum of 2 years were included in this series.

RESULTS

Conversion to laparotomy was necessary in 4 of 40 patients (10%). Thirteen postoperative complications occurred in 13 of 40 patients (30%). At a median follow-up of 38 months (range, 26-90), the median number of bowel movements was 4 per 24 hours (range, 2-10); 15 patients (38%) had no nighttime bowel movements. None of the patients had fecal incontinence or urgency. Thirty-four of the 40 patients (85%) experienced no soiling. Seven patients (18%) took regular antidiarrheal medication. All patients were able to resume all activities practiced prior to illness onset, and 36 of 40 (90%) were satisfied with their overall quality of life (very good or good).

CONCLUSION

Laparoscopic total proctocolectomy with ileal pouch-anal anastomosis provides satisfying mid-term functional outcome.

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.

Systematic Review of Quality of Life following Laparoscopic and open colorectal surgery

OBJECTIVE

To compare the health-related quality of life (HRQoL) of patients following laparoscopic and open colorectal surgery.

METHODS

A systematic review was performed according to Quorum guidelines. Prospective studies comparing the HRQoL of patients after laparoscopic and open colorectal surgery were identified. The primary outcome measure was postoperative quality of life; performance status and cosmesis were secondary outcome measures.

RESULTS

23 studies were identified that satisfied the inclusion criteria; 18 assessed HRQoL, 4 performance status, and 3 cosmesis. It was not possible to perform a meta-analysis due to study heterogeneity. The studies reported outcomes for 2946 patients. The most frequent HRQoL instruments employed were SF-36, EORTC, and GIQLI. 6 studies, using a total of 12 separate measures, evaluated QoL during the first 3 post-operative months: 10 of these measures showed no significant difference, and 2 showed an improved HRQoL with laparoscopy. Twelve further studies evaluated HRQoL up to 5 years post-operatively: 9 showed no difference between the 2 groups, and 3 demonstrated a benefit for laparoscopy. Three of 4 studies assessing performance status on discharge, and all 3 studies assessing cosmesis, reported benefits with the laparoscopic approach.

CONCLUSIONS

The current evidence suggests there is no significant difference in HRQoL following laparoscopic and open colorectal surgery, although there is a lack of good quality data. There is a trend towards improved quality of life outcomes and performance status with laparoscopy in the early post-operative period. There is a need for further research, particularly assessing quality of life in the early post-operative period.

Laparoscopic ileal pouch-anal anastomosis in patients with chronic ulcerative colitis and primary sclerosing cholangitis: a case-matched study

PURPOSE

This study was designed to compare short-term outcomes after laparoscopic ileal pouch-anal anastomosis with those of open ileal pouch-anal anastomosis in patients with both sclerosing cholangitis and ulcerative colitis.

METHODS

Sixteen patients with sclerosing cholangitis and ulcerative colitis undergoing laparoscopic ileal pouch-anal anastomosis were matched with 16 open ileal pouch control subjects by sex, American Society of Anesthesiologists' score, age, and body mass index.

RESULTS

Operative mortality was zero. Operative time was longer in the laparoscopic group (500 +/- 125.8 vs. 381.8 +/- 60.9 minutes, P = 0.03). Thirty-day complications were not significantly different between groups (laparoscopic 25 percent vs. open 43.7 percent, P = 0.26). Length of stay was significantly shorter in the laparoscopic group (5.3 +/- 1.3 days vs. 9.9 +/- 3.3 days open, P < 0.001). Average return of gastrointestinal function was 2.5 days in the laparoscopic group and 4.8 days in the open group (P = 0.001). Time to soft diet was three days in the laparoscopic group and six days in the open group (P < 0.001). All patients were alive and all pouches were intact at last follow-up.

CONCLUSIONS

Laparoscopic ileal pouch-anal anastomosis is feasible with apparent safety in patients with primary sclerosing cholangitis, resulting in shorter duration of hospital stay and quicker return of gastrointestinal function compared with the open procedure with no difference in perioperative complications, reoperations, and readmissions.

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.

Ileal pouch surgery for ulcerative colitis

Ulcerative colitis (UC) is a relapsing and remitting disease characterised by chronic mucosal and submucosal inflammation of the colon and rectum. Treatment may vary depending upon the extent and severity of inflammation. Broadly speaking medical treatments aim to induce and then maintain remission. Surgery is indicated for inflammatory disease that is refractory to medical treatment or in cases of neoplastic transformation. Approximately 25% of patients with UC ultimately require colectomy. Ileal pouch-anal anastomosis (IPAA) has become the standard of care for patients with ulcerative colitis who ultimately require colectomy. This review will examine indications for IPAA, patient selection, technical aspects of surgery, management of complications and long term outcome following this procedure.

Comparison of short-term outcomes of laparoscopic vs open approaches to ileal pouch surgery

AIMS

The present meta-analysis compared short-term outcomes between patients undergoing laparoscopic and open restorative proctocolectomy.

METHODS

A literature search of Medical Literature Analysis and Retrieval System Online, Ovid, Excerpta Medica and Cochrane databases was performed to identify studies published between 1990 and 2006 comparing laparoscopic and open restorative proctocolectomy. A random-effect meta-analytical technique was used, and sensitivity analysis was performed on studies published since 2001, higher-quality papers, those reporting on more than 30 patients and those with matching of patient characteristics.

RESULTS

Ten studies satisfied the selection criteria, including outcomes on 329 patients, 168 (51.1%) of whom underwent laparoscopic resection. Operative time was significantly longer in the laparoscopic group by 86 min (p<0.001) and throughout the subgroup analysis, but this finding was associated with significant heterogeneity. Operative blood loss was less in the laparoscopic group by 84 ml. There was no significant difference in post-operative adverse events between the groups. A statistically significant reduction in length of post-operative stay was observed for laparoscopic patients in high-quality studies and those reporting on more than 30 patients by 1.1 days (p=0.02 in both subgroups) and studies published in or since 2001 by 3.0 days (p=0.004) but not overall.

CONCLUSION

Laparoscopic ileal pouch surgery was associated with longer operative time, lower blood loss, shorter length of hospital stay and similar short-term adverse events compared with open surgery. Comparative data on quality of life and long-term outcomes are currently unavailable. The potential advantage of laparoscopic ileal pouch surgery remains to be established.

Restorative proctocolectomy and ileal pouch-anal anastomosis for familial adenomatous polyposis revisited

Since restorative proctocolectomy (RPC) with ileal-pouch anal anastomosis (IPAA) removes the entire diseased mucosa, it has become firmly established as the standard operative procedure of choice for familial adenomatous polyposis (FAP). Many technical controversies still persist, such as mesenteric lengthening techniques, close rectal wall proctectomy, endoanal mucosectomy vs. double stapled anastomosis, loop ileostomy omission and a laparoscopic approach. Despite the complexity of the operation, IPAA is safe (mortality: 0.5-1%), it carries an acceptable risk of non-life-threatening complications (10-25%), and it achieves good long-term functional outcome with excellent patient satisfaction (over 95%). In contrast to the high incidence in patients operated for ulcerative colitis (UC) (15-20%), the occurrence of pouchitis after IPAA seems to be rare in FAP patients (0-11%). Even after IPAA, FAP patients are still at risk of developing adenomas (and occasional adenocarcinomas), either in the anal canal (10-31%) or in the ileal pouch itself (8-62%), thus requiring lifelong endoscopic monitoring. IPAA operation does not jeopardise pregnancy and childbirth, but it does impair female fecundity and has a low risk of impairment of erection and ejaculation in young males. The latter can almost completely be avoided by a careful "close rectal wall" proctectomy technique. Some argue that low risk patients (e.g. <5 rectal polyps) can be identified where ileorectal anastomosis (IRA) might be reasonable. We feel that the risk of rectal cancer after IRA means that IPAA should be recommended for the vast majority of FAP patients. We accept that in some very selected cases, based on clinical and genetics data (and perhaps influenced by patient choice regarding female fecundity), a stepwise surgical strategy with a primary IPA followed at a later age by a secondary proctectomy with IPAA could be proposed.

Laparoscopic surgery for ulcerative colitis - a meta-analysis

OBJECTIVE

To assess the safety and feasibility of laparoscopic surgery for patients with ulcerative colitis.

METHODS

A search of published studies in English between January 1992 and September 2005 was obtained, using the MEDLINE and PubMed databases and the Cochrane Central Register of Controlled Trials. Two independent assessors reviewed the studies using a standardized protocol. Where raw data, means and standard deviations were available, meta-analysis was performed using the Forest plot review. Studies where medians and ranges were presented were separately analysed.

RESULTS

The duration of surgery for laparoscopic and open procedures were similar (weighted mean difference 62.92 min, P = 0.19). Patients were able to tolerate oral intake significantly earlier, with a weighted mean difference of 1.39 days (P = 0.002), but recovery of bowel function was similar (weighted mean difference 0.73 days, P = 0.36). The length of hospital stay was shorter for patients who had undergone laparoscopic surgery, with a weighted mean difference of 2.64 days (P = 0.003). The complication rate was higher in open colectomy, compared to laparoscopic colectomy (67.6%vs 39.7%, P = 0.005). For restorative proctocolectomy, complication rates were comparable between the laparoscopic and open groups (P = 0.25).

CONCLUSIONS

The time taken to perform laparoscopic surgery is similar to open surgery. Patients are able to tolerate oral intake earlier, and have a shorter hospitalization. Laparoscopic colectomy was safer compared to the open procedure, but both were equally safe for patients who had restorative proctocolectomy. Thus, laparoscopic surgery for ulcerative colitis is both safe and feasible.

Safety, feasibility, and short-term outcomes of laparoscopic ileal-pouch-anal anastomosis: a single institutional case-matched experience. Ann Surg. 2006;243:667-670; discussion 670-672. [PMID: 16633002 DOI: 10.1097/01.sla.00002167]

OBJECTIVE

To compare safety and short-term outcomes of 100 laparoscopic ileal pouch-anal anastomosis (IPAA) versus 200 conventional open IPAA patients.

SUMMARY BACKGROUND DATA

Outcomes of laparoscopic IPAA (LAP-IPAA) have been incompletely characterized. Previous reports are characterized by small numbers of patients and rarely include case-matched or randomized trial methodology. This report describes 100 LAP-IPAA patients case matched to 200 open IPAA patients.

METHODS

Between 1998 and 2004, 100 consecutive LAP-IPAA patients (75 laparoscopic assisted, 25 hand assisted) were identified and case matched to 200 open IPAA control patients by age, operation, gender, date of operation, and body mass index. Operative and postoperative outcomes at 90 days were compared.

RESULTS

A total of 300 patients (180 female) with a median age of 32 years (range, 17-66 years), and a median body mass index of 23 kg/m (range, 16-34 kg/m) underwent IPAA (100 LAP-IPAA, 200 open IPAA). Diagnosis (chronic ulcerative colitis 97%, familial adenomatous polyposis 3%) and previous operative history were equivalent between groups. One intraoperative complication occurred in each group. Overall, the laparoscopic conversion rate was 6%. Median operative time was longer for the LAP-IPAA group (333 minutes versus 230 minutes, P < 0.0001). LAP-IPAA patients had shorter median time to regular diet (3 versus 5 days), time to ileostomy output (2 versus 3 days), length of stay (4 versus 7 days), and decreased IV narcotic use (all P < 0.05. Postoperative morbidity was equivalent (LAP-IPAA = 33%, open IPAA = 37%), mortality was nil, and readmission rates were equal (LAP-IPAA = 21%, open IPAA = 22%). Reoperation was required in 3% of LAP-IPAA and 6.5% of open IPAA patients (P < 0.2) during the first 3 months.

CONCLUSION

LAP-IPAA is equivalent to open IPAA in terms of safety and feasibility. In addition, LAP-IPAA provides significant improvements in short-term recovery outcomes.

Safety, feasibility, and short-term outcomes of laparoscopic ileal-pouch-anal anastomosis: a single institutional case-matched experience

OBJECTIVE

To compare safety and short-term outcomes of 100 laparoscopic ileal pouch-anal anastomosis (IPAA) versus 200 conventional open IPAA patients.

SUMMARY BACKGROUND DATA

Outcomes of laparoscopic IPAA (LAP-IPAA) have been incompletely characterized. Previous reports are characterized by small numbers of patients and rarely include case-matched or randomized trial methodology. This report describes 100 LAP-IPAA patients case matched to 200 open IPAA patients.

Laparoscopic surgery in inflammatory bowel disease: is the future already here?

PURPOSE OF REVIEW

Starting from easy operations like the creation of enterostomies, laparoscopic colorectal surgery has developed quickly towards comprehensive procedures like proctocolectomies. Because of their benign character, inflammatory bowel diseases are an ideal indication for laparoscopic surgical approaches. Inflammatory alterations of bowel and mesentery, however, may demand a high level of laparoscopic experience.

RECENT FINDINGS

In severe anal Crohn's disease, laparoscopic stoma formation has become a standard procedure for low morbidity and reoperation rates. In comparison with conventional bowel resections for Crohn's disease, shorter times to first postoperative bowel movements and hospital stays have been observed with the laparoscopic approach. Even complex cases with previous surgery and enteric fistulas may be managed laparoscopically with a low complication rate. In ulcerative colitis, experience with laparoscopic restorative proctocolectomy is increasing, and its feasibility has been proven in multiple studies. An elevated risk of complications has been observed with increased body mass index and acute inflammation. Function and quality of life outcomes seem to be equivalent for open and laparoscopic surgery.

SUMMARY

Laparoscopic management of Crohn's disease and ulcerative colitis is complex and may be demanding. Its feasibility has been proven in multiple studies and it is offered as a safe and durable alternative for selected patients. The selection criteria are under investigation.

Revolution and evolution: 30 years of ileoanal pouch surgery

Ileal pouch-anal anastomosis (IPAA) has become the standard of care for the 25% of patients with ulcerative colitis who ultimately require colectomy. IPAA is favored by patients because it avoids the necessity for a long-term stoma. This review examines how 3 decades of experience with IPAA has molded current practice, highlighting 5- and 10-year follow-up of large series to determine durability and functional performance, in addition to causes of failure and the management of complications.

Practice parameters for the surgical treatment of ulcerative colitis

The American Society of Colon and Rectal Surgeons is dedicated to assuring high-quality patient care by advancing the science, prevention, and management of disorders and diseases of the colon, rectum, and anus. The Standards Committee is composed of Society members who are chosen because they have demonstrated expertise in the specialty of colon and rectal surgery. This committee was created to lead international efforts in defining quality care for conditions related to the colon, rectum, and anus. This is accompanied by developing Clinical Practice Guidelines based on the best available evidence. These guidelines are inclusive, and not prescriptive. Their purpose is to provide information on which decisions can be made, rather than dictate a specific form of treatment. These guidelines are intended for the use of all practitioners, health care workers, and patients who desire information about the management of the conditions addressed by the topics covered in these guidelines. It should be recognized that these guidelines should not be deemed inclusive of all proper methods of care or exclusive of methods of care reasonably directed to obtaining the same results. The ultimate judgment regarding the propriety of any specific procedure must be made by the physician in light of all of the circumstances presented by the individual patient.

Laparoscopic-assisted vs. open ileal pouch-anal anastomosis: functional outcome in a case-matched series

PURPOSE

Functional outcomes in laparoscopic-assisted ileal pouch-anal anastomosis have been incompletely studied. More than one-year follow-up has rarely been reported in these patients. This study was designed to assess operative, functional, and quality of life outcomes in patients with ulcerative colitis or familial adenomatous polyposis a minimum of one year after.

METHODS

Thirty-three laparoscopic-assisted ileal pouch-anal anastomosis and 33 open ileal pouch-anal anastomosis patients, with a median of 13 months and minimum of 12 months follow-up, were identified from a prospective, laparoscopic database. Functional outcome was prospectively assessed by using a standardized survey. These cohorts were matched by individual patient for year of surgery, age, gender, body mass index, and indication.

RESULTS

Median age was 27 years (open) and 28 years (laparoscopic). There were 27 females and 6 males in each group. All operations occurred between 1999 and 2001. Median body mass index was 22.3 (open) and 21.7 (laparoscopic) groups. There were no significant differences in diagnosis, use of diversion, and anastomotic technique. Postoperative morbidity occurred in 6 percent of the laparoscopic cases and 12 percent of the open cases. Functional outcome after a minimum of one year revealed equivalent median day and median nocturnal number of stools of six to seven and one to two respectively. Consistency of stool, medication usage, and continence were no different between groups. Daytime and nocturnal incontinence was similar. Quality of life in regard to social, home life, family, travel, sports, recreation, and sex life were equivalent.

CONCLUSIONS

The function and quality of life outcomes for patients undergoing laparoscopic-assisted ileal pouch-anal anastomosis seem to be equivalent to our open experience. Laparoscopic-assisted ileal pouch-anal anastomosis offers selected patients a safe, feasible, and durable alternative.

Total laparoscopic proctocolectomy with Brooke ileostomy: a novel incisionless surgical treatment for patients with ulcerative colitis

BACKGROUND

This report describes the clinical benefits and safety of a novel (incisionless) laparoscopic operation for chronic ulcerative colitis.

METHODS

The medical records for four patients with the diagnosis of chronic ulcerative colitis who underwent "incisionless" laparoscopic proctocolectomy with Brooke ileostomy were reviewed. A novel technique was used for successfully performance of four total proctocloectomies with end ileostomies that did not require abdominal incisions. The clinical outcomes measured included time to oral intake, time to ostomy output, operative time, postoperative and intraoperative complications, estimated blood loss, and length of stay.

RESULTS

All the patients recovered without incident intraoperatively and postoperatively. The operative times ranged from 330 to 550 min. Postoperative findings included median time to oral intake (2 days), median time to ileostomy output (2 days), and median length of stay (4 days).

CONCLUSION

This case series demonstrates that an incisionless approach to chronic ulocerative colitis for patients who desire an end ileostomy may be feasible and safe, offering patients short-term recovery and cosmetic benefits.

Laparoscopic surgery for ulcerative colitis

Laparoscopic techniques have revolutionized management of colorectal diseases; however, inflammatory diseases of the intestine have proven challenging because of the technical demands of their nature. Intense investigation and subsequent refinements in technique and technology have recently led to considerable advances and a clear role for laparoscopic management of Crohn's disease. and diverticulitis; laparoscopy for ulcerative colitis has not proven as promising. Laparoscopic procedures for ulcerative colitis require a significant learning curve. Although numerous experienced laparoscopic teams have documented their ability to complete them, long operative times and elevated rates of morbidity in some studies appear to counter the advantages. The question remains as to the universal application and appropriateness of these procedures in surgical management of ulcerative colitis.

Restorative proctectomy after emergency laparoscopic colectomy for ulcerative colitis: a case-matched study

OBJECTIVE

The aim of the study was to evaluate feasibility and safety of restorative proctectomy with ileal pouch anal anastomosis (IPAA) through a Pfannenstiel incision after prior laparoscopic colectomy.

METHODS

Seventeen patients who underwent restorative proctectomy after laparoscopic emergency colectomy for ulcerative colitis (UC) were prospectively evaluated. Results were compared with results of a group of 21 case matched patients that had restorative proctectomy and IPAA via a midline incision in the same period.

RESULTS

Median operation time was longer, although not significantly, in patients who had a restorative proctectomy through a pfannenstiel (186 min) compared to a restorative proctectomy through a midline incision (158 min). Procedure related complications were comparable between the groups, respectively, 1 of 17 patients in the pfannenstiel group and 3 of 21 patients in the median laparotomy group. Median hospital stay in the pfannenstiel group was 10 days and in the midline group 12 days.

CONCLUSIONS

After laparoscopic assisted emergency colectomy for ulcerative colitis, restorative proctectomy is feasible and can be performed safely through a Pfannenstiel incision.

Coloproctectomie totale avec anastomose iléoanale en deux temps vidéoassistée. Expérience initiale de 12 cas

AIM OF THE STUDY

This study reports our early experience in two-stage video assisted restorative proctocolectomy (RPC).

PATIENTS AND METHODS

From May 1999 to May 2003, 12 video assisted RPCs were performed (mucosal ulcerative colitis: n = 11; familial adenomatous polyposis: n = 1). These patients were matched for age, gender, body mass index and indication for surgery, with 12 patients who underwent RPC by laparotomy (open group).

RESULTS

Median operative time was significantly longer in the video assisted RPC group (400 min; range: 360-490) vs open group (300 min; range: 210-390) (P = 0.003). A conversion in midline laparotomy (under the umbilicus) was necessary in 3/12 patients (25%) in the video assisted RPC group. Return to bowel function and oral intake occurred two days earlier after video assisted RPC (respectively, P = 0.009 and P = 0.0001) but length of stay was not significantly shorter in this group. A complication occurred in 3/12 patients (25%) in both groups, which lead to a reoperation in one patient in the open group (ns).

CONCLUSION

Two-stage videoassisted RPC is feasible at the cost of a lengthening of operative time, Nevertheless postoperative results after video assisted RPC are comparable to those obtained after RPC by laparotomy.

Pouch reconstruction in the pelvis

ILEAL POUCH RECONSTRUCTION: Proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the procedure of choice in mucosal ulcerative colitis (MUC) and familial adenomatous polyposis (FAP). Because the disease is cured by surgical resection, functional results, pouch survival prognosis, and disease or dysplasia control are the major determinants of success. There is controversy as to whether the IPAA should be handsewn with mucosectomy or stapled, preserving the mucosa of the anal transitional zone. Crohn's disease is a contraindication for IPAA, but long-term outcome after IPAA is similar to that for MUC in patients with indeterminate colitis who do not develop Crohn's disease. As development of dysplasia and cancer in the ileal pouch have been reported, a standardized surveillance program is mandatory in cases of MUC, FAP, and chronic pouchitis. COLONIC POUCH RECONSTRUCTION: Construction of a colonic pouch is a widely accepted technique to improve functional outcome after low or intersphincteric resection for rectal cancer. Several randomized studies comparing colo-pouch-anal anastomosis (CPA) with straight coloanal anastomosis (CAA) have found the pouch functionally superior. Most controlled studies cover only 1-year follow-up, but randomized studies with 2-year follow-up show similar functional results of CPA and CAA. Evacuation difficulty as initially observed was related to pouch size, and the results with smaller pouches (5-6 cm) are more favorable, showing adequate reservoir function without compromising neorectal evacuation. The transverse coloplasty pouch may offer several advantages to J-pouch reconstruction. Current series question whether the neorectal reservoir is the physiological key of the pouch, but rather the decreased motility. The major advantage reported with colonic pouch reconstruction is the lower incidence of anastomotic complications.
