Ileal pouch-anal anastomosis for chronic ulcerative colitis and familial polyposis coli complicated by adenocarcinoma.

Of 518 patients undergoing the ileal pouch-anal anastomosis (IPAA), 17 (13 with chronic ulcerative colitis [CUC] and four with familial polyposis coli [FPC] ) also had a total of 22 cancers of the colorectum. Tumors were concentrated distally (rectum 6; sigmoid colon 5; proximal colon 11) and were diagnosed preoperatively in eight patients. Histologic grade and stage were as follows: grade I, 36 percent; II, 23 percent; III, 23 percent; IV, 18 percent; stage A, 5 percent; B1, 32 percent; B2, 18 percent; C1 and C2, 45 percent. Median hospital stay was 17 days with no operative mortality. Relaparotomy was required in 35 percent (sepsis in four patients; obstruction in two) and minor procedures were done in 12 percent (anastomotic dilatation in one; rectovaginal fistula in one). Mean frequency of defecation was 6.4/day, 1.0/night; incidence of minor seepage, 17 percent (day), 50 percent night); incidence of pouchitis, 8 percent; intermittent dyspareunia, 17 percent of six women. One patient died from hepatic metastases nine months after operation. IPAA should be considered in favorable cancers complicating CUC or FPC, although it may be contraindicated in advanced rectal cancer, and may be unsuitable in advanced proximal cancer.

[Malignant transformation in ulcerative colitis and surgical implications].

Patients with ulcerative colitis (UC) are at higher risk for cancer. Risk factors are duration of disease, extent of colitis, associated primary sclerosing cholangitis and possibly early onset of UC in childhood. Epithelial dysplasias are considered as precursors of colorectal cancer within the concept of an inflammation-dysplasia-carcinoma sequence. Dysplasia originates multifocally and is difficult to identify by colonoscopy. Histomorphological diagnosis can also be problematical. Surveillance programs utilize colonoscopy with random biopsies to diagnose dysplasia in patients with risk factors. The efficiency of these programs can be markedly increased when certain rules are applied. The ultimate aim must be to perform a proctocolectomy in patients at higher risk before invasive cancer develops. With only a few exceptions, colorectal cancer in UC can be treated by restorative proctocolectomy. Partial resection of the colon should be avoided because of the high frequency of occult carcinomas and multifocal carcinogenesis. There are first results that indicate a higher risk for malignant deterioration in the terminal ileum. After an ileoanal pouch procedure patients with chronic pouchitis seem to have a higher risk for dysplasia. At the moment the risk for malignancy cannot be calculated because of the relatively short follow-up time after ileoanal pouch procedures. However, it is recommended that after restorative proctocolectomy patients be followed by endoscopy and random biopsies for the rest of their lives.

[The continent ileostomy. Current indications, techniques and results].

Over a period of 12 years, 73 patients received a continent ileostomy. 19 Kock pouches were primarily constructed due to contraindications against the ileoanal pouch, 30 ileostomies were converted due to psychological rejection of the incontinent stoma and 9 ileoanal pouches for dysfunction. 15 Kock pouches had to be corrected for nipple valve complications. Perioperative complications (14/73) were related to the Kock pouch in only one third of cases. Surgical late complications of the nipple valve function decreased with technical modifications from 41.1% to 20.0% and then to 4.8%. They could always be dealt with surgically. Pouchitis was observed in 26.8% of cases of ulcerative colitis (11/41), and in 6/15 patients with Crohn's disease (40.0%) complicated ileal recurrences developed. The definitive rate of success over the time was 98.1% in ulcerative colitis and familial adenomatous polyposis (53/54) and 63.2% in other conditions (12/19). Continent ileostomy has become universal and safe method for conversion of any previous operation.

Total proctocolectomy and ileoanal pouch: the role of contrast studies for evaluating postoperative leaks.

BACKGROUND: To assess the role of contrast enemas for the evaluation of leaks in symptomatic and asymptomatic patients after the first stage of restorative proctocolectomy. METHODS: We reviewed the findings of 59 contrast enemas in 40 patients who underwent total proctocolectomy with creation of an ileoanal pouch and a proximal diverting ileostomy. Thirty-seven patients initially underwent routine contrast studies of the ileoanal pouch, and three underwent contrast studies because of suspected fistulas or obstruction. Medical records were also reviewed to determine the clinical presentation and course of these patients. RESULTS: Of 37 patients who underwent routine postoperative contrast enemas, 33 (89%) had normal studies, three (8%) had clinically silent leaks (including two blind-ending tracks from the ileoanal anastomosis and one from the pouch), and one (3%) had pouchitis. In all three patients with unsuspected leaks, ileostomy closure was delayed. In two other patients with abdominal pain and fever, contrast enemas revealed leaks from the ileoanal pouch and distal ileum, respectively. The remaining patient had a contrast enema because of abdominal pain and distention; this patient had a distal ileal obstruction due to adhesions. CONCLUSIONS: Routine postoperative contrast studies revealed clinically silent leaks from the ileal J pouch or ileoanal anastomosis in three of 37 patients (8%) after the first stage of restorative proctocolectomy. Our findings suggest that routine contrast enema can detect clinically silent leaks after this surgery.

Proctocolectomy and ileostomy to pouch surgery for ulcerative colitis.

The development of continence-preserving and sphincter-preserving procedures for operation of ulcerative colitis has a long and interesting history. Reported clinical results on the continent ileostomy (Kock pouch) and the pelvic pouch procedure have often been enthusiastic; and when confronted with the options patients have mostly been in no doubt in selecting "the best operation." However, even if the continent ileostomy and subsequently restorative proctocolectomy were great innovations, it is by no means obvious that they should be recommended as the first choice for all patients. For patients old enough to join in a responsible discussion the pros and cons of the various operations available today must first be carefully described and a decision reached that reasonably meets the patient's wishes and that seems to the surgeon to be soundly based. When comparing the postoperative morbidity, long-term outcome, and quality of life assessment of the options, such a decision is in fact far from easy. Thus panproctocolectomy and ileostomy for ulcerative colitis can be considered a comparatively safe, predictable operation that can cure the patient and allow a short hospital stay, a quick recovery, and rehabilitation. It should also enable the patient to be free of hospital supervision after a year or so. Although there is a major change in body image and sexual disturbances may occur, the operation is in fact still the yardstick by which the other options should be compared. Despite the great attraction of rectum- and sphincter-preserving operations, there will always be patients for whom panproctocolectomy and a conventional end-ileostomy is the superior alternative. The ileal pouch operations are technically demanding and should probably best be restricted to specialist centers even in the future. Complications, if they arise, are often serious, and the hospital stay is often counted in weeks. The functional result may be good, but defects in continence are common and sexual dysfunction is a problem for many of these patients. The pouchitis syndrome is a great disappointment, and recent reports on subsequent epithelial dysplasia and even development of cancer are alarming. The long-term results are in this respect still uncertain. Careful patient selection, with full discussion with the patient and his or her family are essential before a decision on a continent ileostomy or a pelvic pouch is reached. Strong motivation toward avoidance of a conventional ileostomy is important. When compared with the imperfect functional results and the high morbidity associated with the pelvic pouch procedure, there is at present a great revival of interest for total colectomy with ileorectal anastomosis. It is still a useful operation and should be seriously considered particularly in the young. The functional results are comparatively good. Sexual function is well preserved. The use of the operation may enable the teenager to regain good health and finish education and family planning. Due to the cancer risk the need for subsequent supervision must be made clear, however. The operation may also be valuable in elderly patients who would be much bothered by an ileostomy and who are unlikely to live long enough for carcinoma to become a problem. The great advantage is that should a failure occur the other options remain.

Ileocecal reservoir reconstruction after total mesorectal excision: functional results of the long-term follow-up.

BACKGROUND: The aim of this study is to obtain functional results of the long-term follow-up after TME and ileocecal interposition as rectal replacement. METHODS: The study included patients operated on between March 1993 and August 1997 who received an ileocecal interposition as rectal replacement. Follow-up was carried out 3 and 5 years postoperatively. For statistical analysis, the paired t-test, rank test (Wilcoxon), and chi-square or Fisher's exact test were applied; level of significance, P<0.05. RESULTS: Forty-four patients were included in the studies. Of these, five were not available and four patients could not be evaluated (dementia 1, radiation proctitis 1, fistula 1, pouchitis 1). Seventeen patients died during the observation period; 12 died of the disease. Recurrence of the disorder occurred in 2 of 35 patients (5.7%); 26 and 18 patients, 3 and 5 years postoperatively, respectively remained in the study. At 5 years, 78% of the patients were continent; mean stool frequency was 2.5+/-1.6 per day. CONCLUSIONS: Functional results and subjective assessment of ileocecal interposition were constant at 3 and 5 years postoperatively. If construction of a colonic J-pouch is not possible due to lack of colonic length, especially after prior colonic resections, the ileocecal interpositional reservoir may offer an alternative to rectal replacement.

Outcome of ileal pouch after secondary diagnosis of Crohn's disease.

Ileal-pouch anal anastomosis is sometimes performed inappropriately in Crohn's disease patients. The aim of this study was to evaluate long-term results in this subset. In 54 ileal-pouch anal anastomoses performed between 1985 and 1997 for CUD the patient was eventually diagnosed as having Crohn's disease in seven cases. A retrospective review was performed. Definitive diagnosis was established on histopathology, endoscopy, and clinical presentation. The principal outcome factors were pouch failure, reason for failure, and functional results in cases of retained pouch. Patients ranked their quality of life between 1 and 10. We found three failures due to pelvic abscess, anoperineal disease, and anovulvar fistula. The pouch was excised in the latter patient; four patients retained their pouch. Functional results were good in the four (7 year follow-up): 7.25 bowel movements per day, ability to discriminate flatus from feces in three, soiling in one, urgency in one, perianal pad in one, ability to differ bowel movement for 66 min, diet, and antidiarrheal medication all four, pouchitis in one, sexual troubles in one woman, no urinary or obstetric trouble. Quality of life was judged satisfactory by six of the seven patients. Our 13% rate of inadvertent ileal-pouch anal anastomosis is higher than results usually reported. This difference is explained by the diagnostic criteria, whose validity is controversial. Three-stage surgery to decrease inadvertent restorative coloproctectomy is worth considering. Even if results are good when the pouch is functioning, Crohn's disease remains a contraindication to ileal-pouch anal anastomosis because of its high rate of failure and excision.

Causes of failure and life expectancy of the ileoanal pouch.

180 ileoanal pouches constructed over 10 years and followed for at least 2 years (154 for Inflammatory Bowel Disease (IBD) and 26 for Familial Adenomatous Polyposis (FAP)) were reviewed. 23 pouches have been excised to date, 8 remain defunctioned (pouch failure FAP 7.7%, IBD 18.8%). The reasons for excision were: ischemia (n = 6), pelvic sepsis (n = 5), severe stenosis (n = 3), underlying Crohn's disease (n = 3), poor function (n = 5) and fistula (n = 1). The reasons for defunction were: Crohn's disease (n = 1), pelvic sepsis (n = 5) and ileoanal stenosis (n = 2). The projected overall pouch survival rate (Life table analysis) at 5 years was 81% (confidence interval 74-87%). Beyond 7 years, the figures to calculate survival became unreliable (small numbers). There was a significant association between pouch failure and pelvic sepsis (Fisher's exact test P < 0.0001) and between failure and fistula formation (P < 0.02). Multiple regression analysis showed pelvic sepsis and recurrent pouchitis to be independent factors of pouch failure. Pouch failure can occur many years after initial operation. Long-term follow up is recommended.

Terminal ileal transposition procedure in ileoanal anastomosis following proctocolectomy.

We introduced a terminal ileal transposition procedure (TITP) in ileal pouch-anal anastomosis, in which a 50 to 70 cm isolated ileal segment 20 to 40 cm from the ileocecal valve was interposed between the terminal ileum and the anus. Twelve patients underwent this procedure in two or three-staged operations. Mean stool frequency per 24 hours was 4.4 +/- 1.7, and stool consistency was formed and soft in all patients at the mean of 13 months after TITP. We observed neither surgical technique-related complications nor metabolic disorders, except for iron deficiency anemia, during and after the operations. The serum level of vitamin B12 significantly increased after the operation in eight patients (P < 0.05). TITP has advantages such as preventing the terminal ileum from metabolic dysfunction due to pouchitis, avoiding sacrifice of the terminal ileum in the two-staged operation, and obviating the need for reconstruction of ileostomy in the three-staged operation. It may also promote intestinal absorption and reduce late metabolic complications.

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.

Restorative proctocolectomy for pediatric patients with ulcerative colitis.

PURPOSE: A restorative proctocolectomy has become an elective surgical treatment for patients with ulcerative colitis (UC). In children with UC, however, the role of this procedure has not yet been well evaluated. We investigated the postoperative status of pediatric patients with UC regarding the side effects of steroids, postoperative complications, and growth. METHODS: The medical records of 15 patients with UC who underwent a restorative proctocolectomy between August 1993 and October 2003 were retrospectively reviewed. RESULTS: Their mean age was 12.6 +/- 3.4 years (range 5.7-15.7; boys: 9, girls: 6). All patients had total colitis, except for one who had left-sided colitis. The mean cumulative dose of preoperative prednisolone was 6201 +/- 7980 mg (mean +/- SD). The operative indications were an unsuccessful response to medical treatments in 12 patients (80%) and severe colitis in 3 patients (20%). Surgery was performed in one stage in 6 patients and in two stages in 9 patients. Seven patients (47%) demonstrated growth retardation at the time of operation. Steroid-related complications were seen in 3 cases, i.e., steroid myopathy, glaucoma, and cataracts, respectively. As early postoperative complications, an intestinal obstruction was seen in 2 patients, peritonitis in 1, and pancreatitis in 1. As late complications, anastomotic stenosis was observed in 5 patients, pouchitis in 4, residual proctitis in 3, and anal or proctovaginal fistula in 2. An intestinal obstruction, peristomal pyoderma gangrenosum, and dehydration each was seen in 1 patient. A growth "catch-up" was obtained for all but one patient. All patients became free of corticosteroids. CONCLUSION: A restorative proctocolectomy was found to be an effective treatment alternative even in children with UC when conservative therapy proves to be ineffective.

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.

Mid pouch strictureplasty for Crohn's disease after ileal pouch-anal anastomosis: an alternative to pouch excision.

A 33-year-old female developed an isolated stricture of the mid portion of her ileal pouch nine years after proctocolectomy and J-ileal pouch-anal anastomosis for ulcerative colitis. Repeated episodes of pouchitis and partial small-bowel obstruction led to pouchoscopy and pouchography, which demonstrated pouch inflammation and a long, tight, midpouch stricture. Her diagnosis was changed to Crohn's disease and she was treated with azathioprine, budesonide, and infliximab. Repeat pouchoscopy demonstrated mucosal healing but a persistent fibrotic stricture. Pouch reconstruction was performed with a midpouch strictureplasty alleviating her obstructive symptoms. One year after surgery, the patient has no clinical evidence of obstruction and repeat pouchography demonstrates a wider pouch lumen across the strictureplasty site. Strictureplasty is an alternative to pouch excision in the management of patients with Crohn's disease who have an isolated pouch stricture.

Outcome of patients with indeterminate colitis undergoing a double-stapled ileal pouch-anal anastomosis.

INTRODUCTION: The aim of this study was to assess the outcome of patients with indeterminate colitis undergoing double-stapled ileal pouch anal anastomosis. METHODS: A retrospective review of demographic, disease-related, and outcome variables of all patients undergoing double-stapled ileal pouch anal anastomosis from August 1988 to January 2000 was undertaken. All patients were evaluated using the validated American Society of Colon and Rectal Surgeons Fecal Incontinence Severity Index. Patients with familial adenomatous polyposis, those who had undergone pouch revision or had S-configured pouches, and patients with a follow-up of less than three months were excluded from analysis. RESULTS: Three hundred ninety-five patients underwent the double-stapled ileal pouch anal anastomosis; of these 303 patients were included for analysis. The mean duration of follow-up was 40 months. Fifty-six (18.1 percent) had a preoperative diagnosis of indeterminate colitis. Postoperatively, indeterminate colitis was diagnosed in 13 (4.3 percent), mucosal ulcerative colitis in 285 (94 percent), and Crohn's disease in 5 (1.6 percent). The overall complication rate was 37.7 percent, 60 percent, and (30.7) percent in patients with mucosal ulcerative colitis, Crohn's disease, and indeterminate colitis, respectively. Postoperative hemorrhage, abscess, and fistula occurred in 2.4 percent, 6.3 percent, and 3.9 percent, respectively, in patients with mucosal ulcerative colitis, and 0 percent, 15.3 percent, and 7.7 percent, respectively, in patients with indeterminate colitis. Small-bowel obstruction occurred in 8.5 percent, 20 percent, and 7.7 percent of patients with mucosal ulcerative colitis, Crohn's disease, and indeterminate colitis, respectively. Pouchitis occurred in 4.6 percent of patients with mucosal ulcerative colitis but in none of the patients with indeterminate colitis. Dysplasia of the anal transition zone was seen in one patient each with mucosal ulcerative colitis and indeterminate colitis. These patients had consistent follow-up and neither showed any sign of evolution to neoplastic disease. None of the patients with indeterminate colitis had a postoperative diagnosis of Crohn's disease during the follow-up period. Functional outcome was comparable in all three patient groups. CONCLUSION: The outcome of the double-stapled ileal pouch anal anastomosis in patients with indeterminate colitis is similar to that of patients with mucosal ulcerative colitis. Therefore, it is a safe option in patients with indeterminate colitis.

Prevalence and management of prolapse of the ileoanal pouch.

PURPOSE: Known late complications of ileal pouch-anal anastomoses include chronic pouchitis, poor pouch function, or stricture. These may jeopardize the pouch and may require pouch salvage procedures. Prolapse of the ileoanal pouch is a little-known complication infrequently noted in the literature. The objective of this study was to determine the prevalence of this problem and identify approaches used to correct it and salvage the pouch. METHODS: The literature was reviewed for publications describing the diagnosis and treatment of patients with ileoanal pouch prolapse. A survey inquiring about experience with ileoanal pouch prolapse was sent to all North American members and fellows of The American Society of Colon and Rectal Surgeons. The survey assessed the number of years that the respondent had been performing ileal pouch-anal anastomoses and the number and type of pouches constructed. The respondents indicated the prevalence of patients with ileoanal pouch prolapse in their practices and length of time from pouch creation to onset of prolapse. They also were asked to indicate presenting symptoms, need for and method of surgical repair, and outcome. RESULTS: Two hundred and sixty-nine responses were received (response rate, 19.5 percent). Thirty-five respondents indicated that they had assisted in the care of a total of 83 patients with prolapse of the ileoanal pouch. Prolapse symptoms included external prolapse of tissue, sense of obstructed defecation, seepage, and pain. Patients with pouch prolapse most commonly presented within two years of pouch construction. Fifty-two patients required surgery and were managed by a combination of transanal repair, abdominal pouchpexy, and transabdominal revision or removal. The ileoanal pouch was salvaged in all but one case. CONCLUSIONS: Although the incidence of pouch prolapse is relatively low in this survey, the number of cases reported far exceeds the previous known experience. The possibility of this clinical entity should be considered in the differential diagnosis of ileoanal pouch dysfunction. Such recognition should lead to correction of prolapse and pouch salvage in the great majority of patients.

Pregnancy and delivery before and after ileal pouch-anal anastomosis for inflammatory bowel disease: immediate and long-term consequences and outcomes.

PURPOSE: This study was designed to evaluate pregnancy, delivery, and functional outcome in females before and after ileal pouch-anal anastomosis for chronic ulcerative colitis. METHODS: From a prospective database of 1,454 patients who underwent ileal pouch-anal anastomosis for chronic ulcerative colitis between 1981 and 1995, a standardized questionnaire was sent to all female patients aged 40 years or younger at the time of ileal pouch-anal anastomosis (n = 544). RESULTS: The response rate was 83 percent (450/544) with a mean follow-up after ileal pouch-anal anastomosis of 13 years. A total of 141 females were pregnant after the chronic ulcerative colitis diagnosis, but before ileal pouch-anal anastomosis (236 pregnancies; mean, 1.7) and 87 percent delivered vaginally. A mean of five (range, 1-16) years after ileal pouch-anal anastomosis, 135 females were pregnant (232 pregnancies; mean, 1.7). Comparison of pregnancy and delivery before and after ileal pouch-anal anastomosis in the same females (n = 37) showed no difference in birth weight, duration of labor, pregnancy/delivery complications, vaginal delivery rates (59 percent before vs. 54 percent after ileal pouch-anal anastomosis), and unplanned cesarean section (19 vs.14 percent). Planned cesareans occurred only after ileal pouch-anal anastomosis and were prompted by obstetrical concerns in only one of eight. Pouch function at first follow-up after delivery (mean, 7 months) was similar to pregravida function. After ileal pouch-anal anastomosis, daytime stool frequency was the same after delivery as pregravida (5.4 vs. 5.4, not significant) but was increased at the time of last follow-up (68 months after delivery; 5.4 vs. 6.4; P < 0.001). The rate of occasional fecal incontinence also was higher (20 percent after ileal pouch-anal anastomosis and 21 percent pregravida vs. 36 percent at last follow-up; P = 0.01). No difference in functional outcome was noted compared with females who were never pregnant after ileal pouch-anal anastomosis (n = 307). Age and becoming pregnant did not affect the probability of pouch-related complications, such as stricture, pouchitis, and obstruction. CONCLUSIONS: Successful pregnancy and vaginal delivery occur routinely in females with chronic ulcerative colitis before and after ileal pouch-anal anastomosis. The method of delivery should be dictated by obstetrical considerations. Pouch function and the incidence of complications in females with pregnancies seem largely unaffected long-term.

The fate of the ileal pouch in patients developing Crohn's disease.

PURPOSE: Recent studies have suggested that a subset of patients with Crohn's colitis may have a favorable outcome after ileal pouch-anal anastomosis and have advocated elective ileal pouch-anal anastomosis in selected patients with Crohn's disease. We have not offered ileal pouch-anal anastomosis to patients with known Crohn's disease, but because of the overlap in clinical presentation of ulcerative colitis and indeterminate colitis, some patients receiving an ileal pouch-anal anastomosis are subsequently found to have Crohn's disease. We review our experience with these patients to identify potential preoperative predictors of ultimate pouch failure. METHODS: Patients with a final diagnosis of Crohn's disease were identified from an ileal pouch-anal anastomosis registry. These patients are followed prospectively. Preoperative and postoperative clinical and pathologic characteristics were evaluated as predictors of outcome. Median (range) values are listed. RESULTS: Thirty-two (18 females) patients (4.1 percent) with a final diagnosis of Crohn's disease were identified from a registry of 790 ileal pouch-anal anastomosis patients (1980-2002). Patients underwent ileal pouch-anal anastomosis in two stages (11 patients) or three stages (21 patients). The preoperative diagnosis was ulcerative colitis in 24 patients and indeterminate colitis in 8 patients. Median follow-up was 153 (range, 13-231) months. The median time from ileal pouch-anal anastomosis to diagnosis of Crohn's disease was 19 (range, 0-188) months. Complications occurred in 93 percent, including perineal abscess/fistula (63 percent), pouchitis (50 percent), and anal stricture (38 percent). Pouch failure (excision or current diversion) occurred in nine patients (29 percent) at a median of 66 (range, 6-187) months. Two of these 9 patients had preoperative anal disease (not significant). Comparing patients with failed pouches (n = 9) to patients with functioning pouches (n = 23), post-ileal pouch-anal anastomosis perineal abscess (67 vs. 26 percent, P = 0.05) and pouch fistula (89 vs. 30 percent, P = 0.01) were more commonly associated with pouch failure. Preoperative clinical, endoscopic, and pathologic features were not predictive of pouch failure or patient outcome. For those with a functional pouch, 50 percent have been or are currently on medication to treat active Crohn's disease. This group had six bowel movements in 24 (range, 3-10) hours, with leakage in 60 percent and pad usage in 45 percent. CONCLUSIONS: Patients who undergo ileal pouch-anal anastomosis and are subsequently found to have Crohn's disease experience significant morbidity. Preoperative characteristics, including the presence of anal disease, were not predictive of subsequent pouch failure. We choose not to recommend the routine application of ileal pouch-anal anastomosis in any subset of patients with known Crohn's disease.

Management and outcome of pouch-vaginal fistulas following restorative proctocolectomy.

PURPOSE: The aim of this study was to assess the short-term and long-term outcomes of surgical repair of patients with pouch-vaginal fistulas after restorative proctocolectomy. METHODS: A descriptive study was undertaken of all patients developing pouch-vaginal fistulas following restorative proctocolectomy between 1978 and 2003 in a single tertiary referral institution. Kaplan-Meier survival analysis was used to evaluate the time to first pouch-vaginal fistula recurrence and pouch-vaginal fistula-free survival at last follow-up. RESULTS: Sixty-eight patients (mean age, 32.2 years; standard deviation, 10.7) were identified with a median follow-up of 5.5 (range, 0.2-25.5) years. The origin of the pouch-vaginal fistulas was the pouch-anal anastomosis in 52 (76.5 percent) patients, pouch body/top in 9 (13.2 percent), or cryptoglandular or other source in 7 (10.3 percent). Associated early complications in patients with pouch-vaginal fistulas included pelvic sepsis in 20 (29 percent) patients, anastomotic separation in 6 (24 percent), anastomotic stricture in 16 (24 percent), small bowel obstruction in 17 (25 percent), hemorrhage in 2 (3 percent), or pouchitis in 12 (18 percent). Surgery was undertaken in 59 (87 percent) patients with 14 (20.6 percent) of them undergoing pouch excision/diversion or seton drainage. Forty-five (66 percent) patients underwent primary repair. First recurrence of pouch-vaginal fistula occurred in 27 of 45 (60 percent) patients with a median pouch-vaginal fistula-free interval of 1.6 years (95 percent confidence interval, 0.6-2.7). Fourteen (51.9 percent) patients with recurrent pouch-vaginal fistulas healed following one or more repeat procedures. The diagnosis of Crohn's disease was made in eight (12 percent) patients, with pouch-vaginal fistulas persisting or recurring in all patients with Crohn's disease within five years of the primary treatment. Median pouch-vaginal fistula-free survival was 1.4 years for patients with Crohn's disease and 8.1 years for patients with ulcerative colitis or familial adenomatous polyposis. The pouch-vaginal fistula-free survival improved with repeated local or abdominal repairs for patients with ulcerative colitis. The overall pouch failure rate for patients with pouch-vaginal fistulas was 35 percent (median pouch survival, 4.2 years). CONCLUSIONS: Pouch-vaginal fistulas can persist and recur indefinitely, even after repeated repairs. Repair in those patients with Crohn's disease uniformly failed within five years from primary repair. Patients with recurrent pouch-vaginal fistulas and ulcerative colitis should be offered salvage surgery because successful closure following initial failure occurs in approximately 50 percent.
