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.

[Familial adenomatous polyposis. Problems encountered with rectum preservation in surgical treatment and life expectancy].

Familial adenomatous polyposis is a genetically inherited disease with very high risk of colorectal cancer and with a large expression of multiple extracolonic malignancies. In recent years two surgical options are available for the treatment of FAP: total colectomy with ileorectal anastomosis and restorative proctocolectomy with ileoanal reservoir. The preservation of the rectum offers good quality of life and good functional results, but needs an accurate surveillance of the rectal stump and screening for the development of cancer. Restorative proctocolectomy is reserved for patients with large or confluent polyps of the rectum, for older patients and for those who had already had an ileorectal anastomosis and who develops subsequently large adenomas at increased risk for rectal cancer. Prophylactic procedures of surveillance, screening and surgery have reduced in patients at risk the incidence of colorectal cancer. But recently an increased number of malignant extracolonic tumors (gastric cancer, duodenal and periampullary cancer, small intestinal cancer, adrenal and thyroid cancer) and abdominal desmoid tumors, that causes a significant mortality, has been documented. The knowledge of the extracolonic features of FAP suggests a careful follow-up of the patients and the prevention and treatment of upper gastrointestinal cancers and desmoid disease.

[Surgical treatment of hemorrhagic proctocolitis].

Surgical treatment of chronic ulcerative colitis requires restorative proctocolectomy with ilial pouch-anal anastomosis to remove all the disease bowel and provide cure. A one-stage or two-stage procedure can be performed after subtotal colectomy with ileostomy and colostomy. Restorative proctocolectomy is not advised for very old patients or patients with anal sphincter insufficiency. In such cases, total colectomy with ileo-rectal anastomosis is proposed. The rectal stump must be examined regularly by rectoscopy because of the risk of cancer. A proctocolectomy with definitive ileostomy is proposed after pouch-anal excision for pelvic septic complications (5% of ileal pouch-anal anastomoses). Surgical treatment of chronic ulcerative colitis is indicated when medical treatment fails, at onset of fulminant acute colitis, or because of colorectal dysplasia.

Treatment of colorectal and ileoanal anastomotic sinuses.

PURPOSE: This study is designed to describe a technique and report results for treating low anastomotic sinuses. METHODS: Restorative proctocolectomy and complicated low anterior resections were protected with diverting loop ileostomy. Contrast enemas identified anastomotic problems before ileostomy closure. Pouch-anal or colorectal anastomotic sinuses that failed to resolve with observation were treated before intestinal continuity was restored. With the patient receiving regional or general anesthesia, a rigid proctoscope or anoscope was used to identify the sinus opening. The common wall between the sinus and the bowel lumen was divided under direct vision with laparoscopic cautery scissors, and the sinus cavity was debrided with a suction cautery wand placed through the scope. RESULTS: Six patients with anastomotic sinuses have received outpatient treatment in the described manner during the past two years. Four patients had restorative proctocolectomies for ulcerative colitis, and two had low anastomosis for rectal cancer. Three patients presented with pelvic sepsis before the contrast study; the remainder were asymptomatic. Division of anastomotic sinus was performed one to eight months after diagnosis of the sinus. Following division, anastomotic cavities resolved in five patients by 1 month and in one patient by 12 months. In these six patients, there was one dilatable anastomotic stricture but no other anastomotic complications at follow-up 5 to 16 (mean, 9.2) months after sinus division. CONCLUSION: When used in conjunction with fecal diversion, sinus unroofing by division of the common wall between the sinus and bowel lumen treats low pelvic sinuses.

Male sexual function improves after ileal pouch anal anastomosis.

PURPOSE: Restorative Proctocolectomy and Ileal Pouch Anal Anastomosis has become the gold standard surgical therapy for the majority of patients with mucosal ulcerative colitis. However sexual functional disturbances after this procedure can be a concern for patients. Therefore the aim of this study was to determine the outcome of sexual-function related quality of life in male patients undergoing restorative proctocolectomy. METHODS: One hundred and twenty-two male patients who underwent restorative proctocolectomy with ileal pouch anal anastomosis between 1995 and 2000 were evaluated by the validated International Index of Erectile Function (IIEF) scoring instrument. This index scale examines sexual function in five categories. These are erectile function, orgasmic function, sexual desire, intercourse satisfaction and overall satisfaction. The IIEF instrument was administered after surgery and then scores before and after RP/IPAA were evaluated and compared. The significance of age at the time of the surgery, type of surgery, type of anastomotic technique (mucosectomy vs stapled) and septic complications on sexual functional outcome were also investigated. RESULTS: Mean age at the time of the surgery was 39.9 +/- 11.5 years. The mean follow-up period (time between pouch surgery and IIEF completed) was 3.6 +/- 1.8 years. There was statistically significant improvement in 4 of 5 categories of sexual function (erectile function, sexual desire, intercourse satisfaction, and overall satisfaction) where patients had improved scores after surgery compared to prior to surgery. The mean erectile function score increased pre to post surgery by 2.12 points (P = 0.02), which indicates better sexual results. Anastomotic technique and septic complication did not influence the results, however, older age had a negative impact on results. CONCLUSIONS: Despite some adverse sexual functions, male patients who undergo RP/IPAA for the surgical management of their colitis may preserve or improve their overall sexual functional outcome.

Long-acting octreotide in the treatment of diarrhea after pelvic pouch surgery.

After pelvic pouch surgery (restorative proctocolectomy), periodic or continuous diarrhea is common. Distressing diarrhea may be triggered by pouchitis, cuffitis or an anastomotic stricture. Medical therapy with loperamide or diphenoxylate is often unsatisfactory even after the correction of the underlying problem. Seven patients, who earlier had undergone restorative proctocolectomy, were treated with a standard dose of 10 mg of long-acting octreotide (Sandostatin LAR) for prolonged and distressing diarrhea which had not responded to conventional medication. Five of the patients had complete relief of diarrhea. The effect lasted for at least two months after a single dose. Two patients did not respond. No sideeffects were reported. Long-acting octreotide is effective in the treatment of severe diarrhea in patients after pelvic pouch surgery.

Pouch salvage. Long-term outcome.

PURPOSE: The aim of this study was to determine the outcome of pouch salvage operations and the factors that may influence successful reconstructions. METHODS: This retrospective review includes data from 198 patients who had undergone restorative proctocolectomy at a single institution during an 11-year period. All patients who had undergone attempted pouch salvage and who still had a pouch in situ were reviewed by both postal questionnaire and at interview in the outpatients clinic. RESULTS: Of 198 patients who underwent restorative proctocolectomy and ileal pouch-anal anastomosis, 27 (13.6 percent) presented with pouch-specific complications requiring pouch salvage. A further five patients requiring pouch salvage were referred from other centers. Of 32 patients who underwent attempted pouch salvage, 16 (50 percent) had a successful outcome, 12 (37.5 percent) had pouch excision, and 3 (9 percent) are still defunctioned. There was one death (3 percent) in this series. Pelvic sepsis was a major cause of pouch failure, being present in 50 percent (8/16) of failed salvage procedures, and accounting for 58 percent (7/12) of pouch excisions. CONCLUSIONS: Salvage surgery for major complications following ileoanal pouch construction is worthwhile in the absence of major pelvic sepsis. Overall success rate is 50 percent, and these results may be acceptable to highly motivated patients.

Manometric study in ulcerative colitis patients with modified ileal pouch--anal anastomosis.

BACKGROUND AND AIMS: Sphincter-saving operations and construction of intestinal reservoirs aim at additional improvement quality of life of patients with restorative proctocolectomy. The conventional ileoanal anastomosis affects the function of the anal sphincters. There is a need for operative techniques that provide sufficient intraluminal anal pressure and thus a better postoperative continence and quality of life. MATERIALS AND METHODS: Ileal pouch-anal anastomosis (IPAA) after restorative proctocolectomy was carried out in 42 consecutive ulcerative colitis patients (age range: 19-55 years and mean age of 35.52 years). There were 17 males (40.48%) and 25 females (59.52%). IPAA was performed at dentate line, according to a standard method, in 20 patients (47.62% of the cases; mean age of 35.20 years), 19 of which were in 1986-1995 and one patient in 1998. In 1996-2002, however, IPAA was performed after plicating the demucosed segment of rectal residual in 22 patients (52.38% of the cases; mean age of 35.82 years). This modification consisted in strengthening the internal anal sphincter by creation of a smooth muscle cuff through plication of a mucosectomized segment of rectal residual. The basal anal-canal and squeeze pressures were recorded prior to the operation as well as 1 month afterwards and then every 6 months for 2 years. Kelly-Hohlschneider's continence scores after Herold's modification were applied in 14 consecutive patients. RESULTS: Thanks to strengthening the internal anal sphincter by this segment, the basal pressure increased from a preoperative value of 68+/-6 mmHg up to 80+/-6 mmHg at the end of the second postoperative year (P<0.001). This favourable effect could be explained with the additional contractile potential of the plicated rectal segment resulting from the interference of the contractile potential of the internal anal sphincter with that of the smooth muscle cuff. CONCLUSION: The modified IPAA creates a novel and probably functionally active anatomical substrate. The basal anal-canal pressure is maintained sufficiently high through the tone of the smooth muscle cuff and internal anal sphincter. Our preliminary results suggest that the presented technique for performing IPAA may contribute to better functional results.

Preservation of ileocecal junction and entire anal canal in surgery for ulcerative colitis--a "two-sphincter" operation.

Disruption of the terminal ileum and excision of the ileocecal junction during restorative proctocolectomy and formation of a pelvic ileal reservoir may lead to abnormalities of motility, transit, and absorption. We therefore preserved this portion of the gastrointestinal tract in 12 patients who underwent restorative proctocolectomy for ulcerative colitis. In each patient, the entire anal sphincter was preserved without mucosal stripping: the two sphincters were connected by a single loop of ileum without any reservoir. After median follow-up of 12 months, the functional results were similar to those seen with conventional pelvic ileal reservoirs and superior to the results of mucosal proctectomy and straight endoanal ileoanal anastomosis. This operation may be an alternative to standard restorative proctocolectomy for patients with ulcerative colitis.

Poor outcome of a defunctioning stoma after pouch construction for ulcerative colitis.

BACKGROUND: Restorative proctocolectomy for ulcerative colitis can have complications necessitating a later defunctioning ileostomy with uncertain outcome. This analysis was undertaken to assess the outcome in patients needing a later defunctioning ileostomy after pouch construction in patients with ulcerative colitis. METHOD: The notes of our series of 154 patients who underwent restorative proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis were reviewed and 28 patients identified who needed a later defunctioning ileostomy to deal with complications. RESULTS: A later defunctioning ileostomy was necessary in 28 patients to deal with the following complications: sepsis in 11 patients (5 pouches failed), fistulas in 7 (5 pouches failed), poor function including ileoanal stenosis in 5 (all 5 failed), postoperative intraabdominal bleeding in 2 (both saved), pouchitis in 2 (1 excised) and small bowel obstruction in 1 (saved). 16 pouches were eventually excised or permanently defunctioned (59%). CONCLUSION: Complications necessitating a later defunctioning stoma after pouch construction carry a poor prognosis, especially when used for ileoanal stenosis and fistulae.

Review article: ulcerative colitis--surgical indications and treatment.

The indication for surgery is a balance between the severity of the disease despite full medical treatment and the potential disadvantages of surgery. The decision requires cooperation between gastroenterologist and surgeon. Colectomy with ileostomy and preservation of the rectum in the emergency setting is the accepted procedure and can rapidly restore the patient to normal health allowing withdrawal of anti-inflammatory medication. After recovery all surgical possibilities are then open for the future. The elective indications for surgery include failure of medical treatment, retardation of growth in a child or adolescent and neoplastic transformation. The choice of operation includes conventional proctocolectomy, restorative proctocolectomy (RPC) and colectomy with ileo-rectal anastomosis. Each has relative advantages and disadvantages. RPC is the commonest procedure. It offers a satisfactory outcome in 70-90% of patients with a cumulative failure rate of 10-15% over a 10 year period. Causes of failure include sepsis (50%), dysfunction (30%) and pouchitis (10%). In selected cases salvage surgery to avoid failure can be successful with rates of around 70% for outlet obstruction and fistulation and 50% for pelvic sepsis.

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.

Anal canal inflammation after ileal pouch-anal anastomosis. The need for treatment.

UNLABELLED: One technique used during restorative proctocolectomy to prevent loss of continence involves preservation of the anal canal. This technique retains a small amount of colonic mucosa and transitional mucosa that may become inflamed or develop dysplastic or neoplastic changes. PURPOSE: This study was designed to determine the presence and severity of anal canal inflammation and the need for treatment. METHOD: Records of 217 patients with mucosal ulcerative colitis who underwent restorative proctocolectomy with a stapled ileal pouch-anal anastomosis without anal mucosectomy from 1987 through 1990 were retrospectively reviewed. RESULTS: Anal canal inflammation was evident on both endoscopy and biopsy in 48 patients (22.11 percent); 18 patients (8.29 percent) had a normal ileal pouch (9 had symptoms; 5 required topical treatment), and 30 patients (13.82 percent) had associated ileal pouch inflammation (23 with symptoms requiring systemic treatment because of pouchitis; 10 patients had concomitant topical treatment). CONCLUSION: Symptomatic inflammation of the retained mucosa occurred in 32 (14.7 percent) patients. Nine (4.1 percent) patients had inflammation of the anal canal alone, and 23 (10.6 percent) had pouchitis in addition. The need for treatment occurred in 28 (12.9 percent) of the total ((2.3 percent) patients with anal canal inflammation and 23 (10.6 percent) with anal canal inflammation plus pouchitis).

Results of anal or low rectal anastomosis and pouch construction for megarectum and megacolon.

Over a 16-year period 34 patients underwent surgery for idiopathic megarectum or megacolon; 18 had megarectum with or without megasigmoid, one megacolon only and 15 megarectum and total megacolon (nine with a previous colectomy). Ten patients underwent low rectal or anal anastomosis without pouch formation (colodistal proctostomy, eight; coloanal anastomosis, two), eight had colonic pouch-anal anastomosis (J pouch) and 14 had an ileal J pouch after restorative proctocolectomy; one underwent subtotal colectomy with ileorectal anastomosis and one loop ileostomy alone. There was one death, from intestinal obstruction 24 months after operation. Twenty-seven of 32 evaluable patients without a stoma became fully continent following resection and sphincter-saving procedures. Three of 18 had a poor result after resection for megarectum because of recurrent constipation. One of 14 patients became incontinent after restorative proctocolectomy for megacolon and megarectum and in a further four persistent abdominal distension and pain was treated by pouch excision.

Serum tenascin-C is an indicator of inflammatory bowel disease activity.

Tenascin-C is a multifunctional matrix protein that is induced in inflammation and neoplasia. In the colonic mucosa of ulcerative colitis patients tenascin-C indicates tissue repair, and mucosal concentrations are correlated with local disease activity. We prospectively examined the relationship between serum concentrations of tenascin-C parameters of disease activity in surgically treated patients with ulcerative colitis and patients with inflammatory bowel disease (IBD). Perioperative serum concentrations were quantified by ELISA in 58 patients admitted for restorative proctocolectomy; controls were 37 patients with familial adenomatous polyposis receiving the same treatment. We also measured tenascin-C serum levels in 47 patients with ulcerative colitis and Crohn's disease who were receiving nonsurgical treatment. Preoperative serum tenascin-C levels were significantly higher in ulcerative colitis patients than in controls (17.2 +/- 14.6 microg/ml vs. 3.2 +/- 1.7 microg/ml) and were significantly correlated with clinical and histological parameters of disease activity; levels decreased significantly after restorative proctocolectomy. Serum tenascin-C levels were also correlated with the course of disease activity in conservatively treated IBD patients. Tenascin-C is thus not disease-specific. However, it does indicate the activity of IBD and may reflect the degree of tissue remodeling. The tenascin-C levels therefore offers a novel serum parameter for assessing disease activity and monitoring therapy in patients with IBD.

Current controversies in pouch surgery.

Restorative proctocolectomy with ileal pouch anal anastomosis has become the most commonly used procedure for elective treatment of patients with mucosal ulcerative colitis and familial adenomatous polyposis. Since its original description, the procedure has been modified in an attempt to obtain optimal functional results with low morbidity and mortality, and yet provide a cure for the disease. These modifications of the technique are discussed in this review, limited to the current points of controversy. We reviewed the current literature describing restorative proctocolectomy with ileal pouch anal anastomosis. The current "hot topics" for debate are transanal mucosectomy with hand-sewn anastomosis versus the double-stapled technique, the use of diverting ileostomy, indeterminate colitis, the role of laparoscopy, and indications for pouch surgery in the elderly. Longer follow-up of patients and increased knowledge and experience with pouch surgery, coupled with active prospective evaluation of the procedure are required to settle these issues. Patients must be fully informed to understand inherent risks of each choice.

Does an ileoanal pouch offer a better quality of life than a permanent ileostomy for patients with ulcerative colitis?

Although an ileoanal pouch is frequently offered to patients with ulcerative colitis, it is still not clear to what extent this operation offers advantages over a permanent ileostomy. The aim of this study was to determine whether patients with a pouch have less morbidity and a better quality of life than a matched group of patients with a Brooke ileostomy. Nineteen patients (12 males and 7 females, median age 41 years) who had undergone total colectomy and ileoanal pouch formation for ulcerative colitis were individually matched with patients who had had a panproctocolectomy and ileostomy; patients were matched for disease process, sex, age, socioeconomic status, and time since surgery. Quality of life was assessed using the Short-Form 36 version 2 questionnaire, the inflammatory bowel disease questionnaire, and a few additional questions on perception of body image. The scores were compared using the nonparametric Wilcoxon signed-rank test for paired samples. The number and type of postoperative complications, as well as the number of operative stages, were recorded prospectively. Restorative proctocolectomy was associated with a significantly better perception of body image than a permanent stoma, although quality of life in general was similar in both groups. Patients with a pouch had more long-term complications than patients with an ileostomy within the same period of time (52.6% vs. 26.3%). The median number of stages for pouch construction was two, compared to a median of one stage for an ileostomy (P<0.0001). Because of the high long-term complication rate and the relatively small quality-of-life advantage associated with restorative proctocolectomy, patients need to be counseled thoroughly before agreeing to this operation.

Vaginal delivery after ileal pouch-anal anastomosis: a word of caution.

PURPOSE: This study was designed to evaluate the impact of childbirth on anal sphincter integrity and function, functional outcome, and quality of life in females with restorative proctocolectomy and ileal pouch-anal anastomosis. METHODS: The patients who had at least one live birth after ileal pouch-anal anastomosis were asked to return for a comprehensive assessment. They were asked to complete the following questionnaires: the Short Form-36, Cleveland Global Quality of Life scale, American Society of Colorectal Surgeons fecal incontinence severity index, and time trade-off method. Additionally, anal sphincter integrity (endosonography) and manometric pressures were measured by a medical physician blinded to the delivery technique. Anal sphincter physiology also was evaluated with electromyography and pudendal nerve function by nerve terminal motor latency technique. RESULTS: Of 110 eligible females who had at least one live birth after ileal pouch-anal anastomosis, 57 participated in the study by returning for clinical evaluation to the clinic and 25 others by returning the quality of life and functional outcome questionnaires. Patients were classified into two groups: patients who had only cesarean section delivery after ileal pouch-anal anastomosis (n = 62) and patients who had at least one vaginal delivery after ileal pouch-anal anastomosis (n = 20). The mean follow-up from the date of the most recent delivery was 4.9 years. The vaginal delivery group had significantly higher incidence of an anterior sphincter defect by anal endosonography (50 percent) vs. cesarean section delivery group (13 percent; P = 0.012). The mean squeeze anal pressure was significantly higher in the patients who had only cesarean section delivery (150 mmHg) after restorative proctocolectomy than patients who had at least one vaginal delivery (120 mmHg) after restorative proctocolectomy (P = 0.049). Quality of life evaluated by time trade-off method also was significantly better in the cesarean section delivery group (1) vs. vaginal delivery group (0.9; P < 0.001). CONCLUSIONS: The risk of the sphincter injury and quality of life measured by time trade-off method are significantly worse after vaginal delivery compared with cesarean section in patients with ileal pouch-anal anastomosis. In the short-term, this does not seem to substantially influence pouch function or quality of life; however, the long-term effects remain unknown, thus obstetric concern may not be the only factor dictating the type of delivery in this group of patients. A planned cesarean section may eliminate these potential and factual concerns in ileal pouch-anal anastomosis patients.
