Difference in the frequency of pouchitis between ulcerative colitis and familial adenomatous polyposis: is the explanation in peripouch fat?

AIM: Patients with ulcerative colitis (UC) have an unexplained higher incidence of pouchitis and a greater amount of peripouch fat compared with patients with familial adenomatous polyposis (FAP). The aims of this study were to compare the peripouch fat areas between patients with UC and patients with FAP, and to explore relationship between peripouch fat and pouchitis or chronic antibiotic-refractory pouchitis (CARP). METHOD: Patients with an abdominal CT image from our prospectively maintained Pouch Database were included. Abdominal fat and peripouch fat were measured on CT images at different levels or planes. Comparisons of peripouch fat and CARP were performed before and after propensity score matching. RESULTS: A total of 277 patients with UC and 40 patients with FAP were included. Compared with patients with FAP, patients with UC were found to have a higher incidence of pouchitis (58.5% vs 15.0%, P < 0.001) and CARP (24.5% vs 2.5%, P = 0.002) and a higher total peripouch fat area (P = 0.030) and mesenteric peripouch fat area (P = 0.022) at Level-3. Univariate and multivariate analyses showed that diagnosis (UC vs FAP) and peripouch fat areas at Level-3 and Level-5 were independent risk factors for CARP. With propensity score matching, 38 pairs of patients with UC and FAP were matched successfully. After matching, patients with UC were found to have higher total peripouch fat area and higher mesenteric peripouch fat area at Level-3, and a higher incidence of pouchitis (57.9% vs 13.2%, P < 0.001) and CARP (23.7% vs 2.6%, P = 0.007). CONCLUSION: Our study demonstrates that patients with UC have more peripouch fat than those with FAP, which may explain the difference in the frequency of pouchitis and CARP between these groups of patients.

Outcomes of ileal pouch-anal anastomosis without primary diverting loop ileostomy if postoperative sepsis develops.

BACKGROUND: The aim of the present study was to assess the short-term and long-term consequences of diverting loop ileostomy (DLI) omission in ileal pouch-anal anastomosis (IPAA) surgery complicated by postoperative pelvic sepsis. METHODS: This was a retrospective review of a prospectively maintained database. Of 4031 patients who underwent IPAA in 1983-2014, 357 developed IPAA-related pelvic sepsis with or without anastomotic dehiscence. Patients with Crohn's disease or cancer were excluded. The patient cohort was divided into two groups, depending on the presence or absence of DLI. Patient characteristics, short-term and long-term outcomes were compared. Long-term pouch survival was estimated with the Kaplan-Meier method. Quality of life (QOL) in the groups was compared at the latest follow-up. RESULTS: Three hundred and twenty-six patients developing pelvic sepsis had diversion at the time of IPAA (D group) and in 31 who developed pelvic sepsis DLI had been omitted (O group). The length of hospital stay was significantly longer in the O group 11.5 (3-33) days versus 8 (2-59) days in the D group (p = 0.006). Forty-eight percent of patients from the O group with anastomotic leak underwent reoperation and had a DLI formed at this second procedure versus 12% in the D group requiring reoperation (p < 0.0001). In long-term follow-up, there was no difference in pouch survival between the groups: 99 versus 97% after 5 years and 88 versus 87% after 10 years, in the O group and D group, respectively (p = 0.40). There was no difference in QOL observed between the groups. CONCLUSIONS: Omission of DLI in selected patients who had IPAA surgery did not increase pouch failure or adversely affect QOL in the long term, if pelvic sepsis occurred.

Restorative proctocolectomy: an example of how surgery evolves in response to paradigm shifts in care.

AIM: Surgical technique constantly evolves in response to the pressure of progress. Ileal pouch anal anastomosis (IPAA) is a good example. We analysed the effect of changes in practice on the technique of IPAA and its outcomes. METHOD: Patients undergoing primary IPAA at this institution were divided into three groups by date of the IPAA: those operated from 1983 to 1993, from 1994 to 2004 and from 2005 to 2015. Demographics, patient comorbidity, surgical techniques, postoperative outcomes, pouch function and quality of life were analysed. RESULTS: In all, 4525 patients had a primary IPAA. With each decade, increasing numbers of surgeons were involved (decade I, 8; II, 16; III, 31), patients tended to be sicker (higher American Society of Anesthesiologists score) and three-staged pouches became more common. After an initial popularity of the S pouch, J pouches became dominant and a mucosectomy rate of 12% was standard. The laparoscopic technique blossomed in the last decade. 90-day postoperative morbidity by decade was 38.3% vs 50% vs 48% (P < 0.0001), but late morbidity decreased from 74.2% through 67.1% to 30% (P < 0.0001). Functional results improved, but quality of life scores did not. Pouch survival rate at 10 years was maintained (94% vs 95.2% vs 95.2%; P = 0.06). CONCLUSION: IPAA is still evolving. Despite new generations of surgeons, a more accurate diagnosis, appropriate staging and the laparoscopic technique have made IPAA a safer, more effective and enduring operation.

Long-term outcomes after circular stapled hemorrhoidopexy versus Ferguson hemorrhoidectomy.

BACKGROUND: We aimed to compare long-term outcomes and quality of life in patients undergoing circular stapled hemorrhoidopexy to those who had Ferguson hemorrhoidectomy. METHODS: Patients who underwent Ferguson hemorrhoidectomy and circular stapled hemorrhoidopexy between 2000 and 2010 were reviewed. Long-term follow-up was assessed with questionnaires. RESULTS: Two hundred seventeen patients completed the questionnaires. Mean follow-up was longer in the Ferguson hemorrhoidectomy subgroups (7.7 ± 3.4 vs. 6.3 ± 2.9 years, p = 0.003). Long-term need for additional surgical or medical treatment was similar in the Ferguson hemorrhoidectomy and circular stapled hemorrhoidopexy groups (3 vs. 5%, p = 0.47 and 3% in both groups, p > 0.99, respectively). Eighty-one percentage of Ferguson hemorrhoidectomy and 83% of circular stapled hemorrhoidopexy patients stated that they would undergo hemorrhoid surgery again if needed (p = 0.86). The symptoms were greatly improved in the majority of patients (p = 0.06), and there was no difference between the groups as regards long-term anorectal pain (p = 0.16). The Cleveland global quality of life, fecal incontinence severity index, and fecal incontinence quality of life scores were similar (p > 0.05). CONCLUSIONS: This is one of the longest follow-up studies comparing the outcomes after circular stapled hemorrhoidopexy and Ferguson hemorrhoidectomy. Patient satisfaction, resolution of symptoms, quality of life, and functional outcome appear similar after circular stapled hemorrhoidopexy and Ferguson hemorrhoidectomy in long term.

Risk of adhesive obstruction after colorectal surgery: the benefits of the minimally invasive approach may extend well beyond the perioperative period.

BACKGROUND: Risk of adhesive small-bowel obstruction (SBO) is high following open colorectal surgery. Laparoscopic surgery may induce fewer adhesions; however, the translation of this advantage to a reduced rate of bowel obstruction has not been well demonstrated. This study evaluates whether SBO is lower after laparoscopic compared with open colorectal surgery. METHODS: Patients who underwent laparoscopic abdominal colorectal surgery, without any previous history of open surgery, from 1998 to 2010 were identified from a prospective laparoscopic database. Details regarding occurrence of symptoms of SBO (colicky abdominal pain; nausea and/or vomiting; constipation; abdominal distension not due to infection or gastroenteritis), admissions to hospital with radiological findings confirming SBO, and surgery for obstruction after the laparoscopic colectomy were obtained by contacting patients and mailed questionnaires. Patients undergoing open colorectal surgery for similar operations during the same period and without a history of previous open surgery also were contacted and compared with the laparoscopic group for risk of obstruction. RESULTS: Information pertaining to SBO was available for 205 patients who underwent an elective laparoscopic procedure and 205 similar open operations. The two groups had similar age, gender, and sufficiently long duration of follow-up. Despite a significantly longer duration of follow-up for the laparoscopic group, admission to hospital for SBO was similar between groups. Patients who underwent laparoscopic surgery also had significantly lower operative intervention for SBO (8% vs. 2%, p = 0.006). CONCLUSIONS: Although the rate of SBO was similar after laparoscopic and open colorectal surgery, the need for operative intervention for SBO was significantly lower after laparoscopic operations. These findings especially in the context of the longer follow-up for laparoscopic patients suggests that the lower incidence of adhesions expected after laparoscopic surgery likely translates into long-term benefits in terms of reduced SBO.

Adhesions after laparoscopic and open ileal pouch-anal anastomosis surgery for ulcerative colitis.

BACKGROUND: Emerging evidence suggests that a laparoscopic approach to colorectal procedures generates fewer adhesions. Even though laparoscopic ileal pouch-anal anastomosis (IPAA) is a lengthy procedure, the prospect of fewer adhesions may justify this approach. The aim of this study was to assess abdominal and adnexal adhesion formation following laparoscopic versus open IPAA in patients with ulcerative colitis. METHODS: A diagnostic laparoscopy was performed at time of ileostomy closure. All abdominal quadrants and the pelvis were video recorded systematically and graded offline. The incisional adhesion score (IAS; range 0-6) and total abdominal adhesion score (TAS; range 0-10) were calculated, based on the grade and extent of adhesions. Adnexal adhesions were classified by the American Fertility Society (AFS) adhesion score. RESULTS: A total of 43 patients consented to participate, of whom 40 could be included in the study (laparoscopic 28, open 12). Median age was 38 (range 20-61) years. There was no difference in age, sex, body mass index, American Society of Anesthesiologists grade and time to ileostomy closure between groups. The IAS was significantly lower after laparoscopic IPAA than following an open procedure: median (range) 0 (0-5) versus 4 (2-6) respectively (P = 0·004). The TAS was also significantly lower in the laparoscopic group: 2 (0-6) versus 8 (2-10) (P = 0·002). Applying the AFS score, women undergoing laparoscopic IPAA had a significantly lower mean(s.d.) prognostic classification score than those in the open group: 5·2(3·7) versus 20·0(5·6) (P = 0·023). CONCLUSION: Laparoscopic IPAA was associated with significantly fewer incisional, abdominal and adnexal adhesions in comparison with open IPAA.

Surgery of recurrent parastomal hernia: direct repair or relocation?

PURPOSE: Parastomal hernia is a common late complication after stoma creation. The management options are many; unfortunately, most literature suggests unsatisfactory results. There are few studies comparing the outcomes after repair of parastomal hernias especially in recurrent cases, and the results are controversial. The aim of this study was to compare outcomes after repair of recurrent parastomal hernias between direct repair (DR) and relocation (RL). METHOD: We performed a retrospective chart review of patients who underwent direct repair or RL for recurrent parastomal hernia during the period between 1990 and 2005. Perioperative data and re-recurrence rates were obtained and analysed with appropriate statistical methods. RESULTS: With mean follow-up time of 2 years, 50 operations were available for evaluation; 27 (54%) DR and 23 (46%) RL [five same-side RL (SSRL) and 18 opposite-side RL (OSRL)]. There were no deaths and there were similar complication rates between groups. Four of five (80%) SSRL had a re-recurrent parastomal hernia. Considering only DR with OSRL, although OSRL had longer operative time and hospital stay than DR, the re-recurrence rate was lower (38%vs 74%; P = 0.02). However, with Kaplan-Meier calculated and longer predicted follow-up time, re-recurrence rates were similar (Log rank P = 0.09). CONCLUSION: Recurrent parastomal hernia repair is associated with high re-recurrence rates.OSRL seems to have promising short-term outcomes; however, whether these results hold up long-term remains unclear. Therefore, larger cohorts of patients with longer follow-up or prospective randomized trials are needed.

Combined surgery in pelvic organ prolapse is safe and effective.

OBJECTIVE: In women, rectal prolapse is often accompanied by other signs of generalized pelvic floor weakness including uterine and bladder prolapse. The purpose of this study was to compare whether there are differences in outcomes of rectal prolapse surgery between women having combined pelvic organ prolapse (POP) surgery with a urologist or urogynecologist (CS) vs those having abdominal rectal prolapse surgery alone (RP). METHOD: Charts were reviewed to collect perioperative data on those having surgery from 1995 to 2001. Phone surveys were conducted to obtain Cleveland Clinic Foundation (CCF) Incontinence score, Knowles-Eccersley-Scott-Symptom (KESS) Constipation Score, Short Form 36 (SF-36) quality of life score and recurrence rate. Appropriate statistical analysis was performed. RESULTS: Ninety-four operations were performed (23 CS and 71 RP). Forty-six (49%) could be contacted by phone. Mean follow-up was similar in both groups (CS 4.1 vs RP 3.6 years; P = 0.796). There were no significant differences between both groups regarding age, American Society of Anesthesiology classification Score, complications, length of hospital stay, CCF Incontinence score, KESS Constipation Score, SF-36 Score and recurrence rate of rectal prolapse. The operative time (CS 226 vs RP 122 min; P < 0.001) and blood loss (CS 377 vs RP 183 ml; P < 0.001) were significantly increased in the CS group. CONCLUSION: Combined surgery for POP is safe and effective when considering outcomes of rectal prolapse surgery. Therefore surgeons should not hesitate to address all pelvic floor issues during the same operation by working in partnership with the anterior pelvic floor colleagues.

Outcomes for case-matched laparoscopically assisted versus open restorative proctocolectomy.

BACKGROUND: The aim of this study was to compare safety, early and late outcomes, quality of life and functional results of laparoscopically assisted versus open ileal pouch-anal anastomosis (IPAA). METHODS: Patients who had laparoscopically assisted IPAA between 1992 and 2007 were identified from a database and retrospectively matched for age, sex, body mass index (BMI) and operation date to patients who had open IPAA at a ratio of 1:2. Intraoperative, postoperative and long-term functional outcomes were compared. Quality of life was determined by the Cleveland Global Quality of Life scale at 1 and 5 years. RESULTS: A total of 119 patients (59 men, 60 women; mean(s.d) age 35.5(14.2) years, BMI 24.7(5.0) kg/m(2)) had laparoscopically assisted IPAA, with conversion in nine patients (7.6 per cent); these were compared with 238 patients who had open IPAA. The 30-day and long-term results were similar, as well as quality of life at 1 and 5 years, except that patients in the laparoscopic group had shorter median time to stoma action (2 versus 3 days; P = 0.001) and marginally shorter hospital stay. Median operating times were longer in the laparoscopic group (272 versus 163 min; P = 0.040). CONCLUSION: Laparoscopically assisted IPAA had similar outcomes to open IPAA, but with some short-term advantages.

Current considerations in the management of rectovaginal fistula from Crohn's disease.

Rectovaginal fistulas are dreaded complications of Crohn's disease. Accurate assessment is essential for planning management. Treatment options range from observation to medical therapeutics to the need for surgical intervention. Ultimately, establishing reasonable expectations is mandatory when treatment algorithms are considered. In this article, we review the evaluation of these fistulas and the current options to consider in the treatment of Crohn's related rectovaginal fistula.

Complications and functional results after ileoanal pouch formation in obese patients.

OBJECTIVE: Ileoanal pouch formation (IPAA) can be technically challenging in obese patients, and there is little data evaluating results after the procedure in these patients. We compare outcomes for patients with a body mass index (BMI) > or =30 undergoing IPAA when compared with those for patients with BMI <30. METHODS: Retrospective analysis of prospectively accrued data for patients with BMI > or =30 undergoing IPAA. Patient and disease-related characteristics, complications, long-term function, and quality of life (QOL) using the Cleveland Global Quality of Life scale (CGQL) were determined for this group of patients (group B) and compared with those for patients with BMI <30 (group A). Kruskal-Wallis and Wilcoxon rank sum tests were used to compare quantitative or ordinal data and chi-square or Fisher's exact tests for categorical variables. Long-term mortality and complication rates were estimated using the Kaplan-Meier method with group comparisons performed using log rank tests. RESULTS: There were 345 patients (median BMI 32.7) in group B and 1,671 patients in group A. When the cumulative risk of complications over 15 years was compared, group B patients had a significantly higher chance of getting a complication (94.9% vs 88%, p = 0.006). The rates of pelvic sepsis (6.7% vs 5.3%, p = 0.3), pouchitis (58.1 vs 54.4%, p = 0.9), pouch failure (6% vs 4.5%, p = 0.9), and hemorrhage (5.6% vs 4.8%, p = 0.7) were similar for group B and group A. Group B patients, however, had a significantly higher risk of the development of wound infection (18.8% vs 8.1%, p < 0.001) and anastomotic separation (10.4% vs 5.4%, p < 0.001), whereas group A patients had a higher rate of development of obstruction over time (26.7% vs 22.3%, p = 0.02). Long-term outcome including QOL and function after 15 years was comparable between groups. CONCLUSIONS: Although technically demanding, IPAA can be undertaken in obese patients with acceptable morbidity. Good long-term functional results and QOL that is comparable to nonobese patients may be anticipated.

Crohn's disease: a patient's perspective.

AIM: As healthcare providers for Crohn's disease, we assume that we have a good understanding of the disease progression and its symptoms. The aim of this study was to gather information about what patients with Crohn's disease think are relevant to their symptoms and what helps them cope with this lifelong benign disease. MATERIALS AND METHODS: A questionnaire was sent to all patients with a diagnosis of Crohn's disease seen in the Digestive Disease Center in the last 5 years. The returned forms were downloaded into a database and sent for analysis. RESULTS: Sixty-two percent of respondents were female. One third were between the ages of 35 and 50 years. Seventy percent were married. Thirty-eight percent had a graduate degree, 19% were unemployed. Fifty percent still smoked, half of them less than one pack a day. Sixty-eight percent said that their symptoms affected work, and one fourth changed jobs due to this. Foods worsened symptoms in 60%, with a decrease in symptoms while on low fiber foods and white meats. Lifestyle change worsened symptoms in 66%. A change in the caregiver was not a significant stressor. More than half used Remicade, with one third stating that it was helpful. Eight percent had never used steroids. Alcohol increased symptoms in 40%. Factors that did not cause a significant change were children at any age, pregnancy, menopause, and hormone replacement therapy. Surgery caused half the patients to improve for many years, although one third felt a lowered self-esteem postoperatively. CONCLUSION: Patients with Crohn's disease should be managed in a more comprehensive manner to provide optimal care. Thus, a team approach that includes a dietician and counselor should be considered as an integral part of this team. This will allow patients to have enhanced skills to cope with changes in their symptoms, whether they are due to the disease itself or the changes in their routine.

Portal vein thrombi after restorative proctocolectomy: serious complication without long-term sequelae.

PURPOSE: Portal vein thrombi have been observed after restorative proctocolectomy and ileal pouch-anal anastomosis, and present as a clinical spectrum of abdominal pain, fever, and leukocytosis. Anticoagulation treatment is usually associated with resolution of symptoms. However, the long-term consequences and effect on pouch function are not known. The purpose of this study was to analyze the long-term functional outcome of patients with confirmed portal vein thrombi after restorative proctocolectomy. METHODS: A retrospective study of all patients undergoing restorative proctocolectomy from January 1997 to 2000 was performed. A case-control study was designed that matched 37 patients with confirmed portal vein thrombi in this period with 133 patients without portal vein thrombi; the groups were compared with respect to pouch function and quality of life by using the Global Cleveland Clinic Quality of Life Questionnaire for pelvic pouch patients. RESULTS: The mean follow-up was 4.73 (range, 4.21-7.28) years. The percentage of male patients was 58.8. The most common diagnosis was ulcerative colitis (62.4 percent). There were no significant differences between portal vein thrombi patients and controls with respect to pouch function (number of bowel movements, urgency, incontinence), episodes of pouchitis, or quality of life. CONCLUSIONS: Portal vein thrombi can be a serious complication after restorative proctocolectomy that usually resolves with anticoagulation therapy. Long-term pouch function and quality of life are not affected.

Female bowel function: the real story.

PURPOSE: There has been minimal research done on normal female bowel habits. Because we do not know what is normal, this affects counseling of patients and research. The aim of this study was to conduct a survey of females with no bowel pathology to obtain a baseline of normal bowel function and examine any normal changes that occur during a woman's lifetime. METHODS: Females accompanying patients to our hospital and clinic were invited to fill out an IRB-approved questionnaire after excluding those with current bowel pathology, depression, a stoma, or were wheelchair bound. RESULTS: Four hundred twenty-five of 528 questionnaires of females who reported they had normal bowel habits were evaluated. The age range was from 18 to 80 years and comparison was according to age, race, and parity. Fifty-one percent had one bowel movement daily while 30 percent reported fewer. Overall, 15 percent reported constipation, which was higher in African-American females (26 percent) vs. Caucasian females (14 percent), P = 0.08. The average time for a bowel movement was 5-6 minutes, which was longer in African-American females (7.7 min) vs. Caucasian (5.0 min), P = 0.002. Younger females had changes in their bowel pattern reported as soft stool usually associated with their menstrual cycle; this was seen mostly in single females. Menopause did not affect bowels. Thirty-six percent of parous females reported occasional stool incontinence. Flatal incontinence was seen occasionally in over 50 percent of females, more frequently in those over 35 years old. Seventy-four percent of parous females reported incontinence to gas. One-third of females read on the toilet, with a majority doing so to relax or to be distracted and with African-American females reading more (54 percent) vs. Caucasian (32 percent), P = 0.004. Interestingly, Caucasian females read to conserve time (26 percent) vs. African-Americans (4 percent), P = 0.02. Fiber as a supplement was taken by only 8 percent. Foods affected bowel function in all age groups, while travel and exercise did not. Stress affected a change in 35 percent in the 18 to 50-year group. CONCLUSION: There is a vast diversity in what is considered normal female bowel habits. One daily bowel movement is not the norm. Normal older females and those who have had children report more flatal incontinence. One-third experience some element of fecal incontinence. Foods most commonly caused a change in bowel pattern, followed by menstruation, stress, and childbirth. A vast majority do not take fiber as a supplement.

Multimedia article. Success of episioproctotomy for cloaca and rectovaginal fistula.

PURPOSE: Surgical repair of rectovaginal fistula with an advancement flap has had suboptimal results. The existing literature documenting episioproctotomy as a surgical option in females with rectovaginal fistula or cloaca is limited. This study was designed to examine our experience with episioproctotomy in this group. Additionally we were interested in risk factors, which might predict failure. METHODS: All females who had repair of a rectovaginal fistula or cloaca with episioproctotomy from 1998 to 2004 were studied. Data were collected from chart review and telephone contact. This included demographics, body mass index, tobacco use, Crohn's disease, previous surgery, and diverting stoma. RESULTS: Data were obtained from 42 females (mean age, 39.2 (range, 25-70) years). The mean follow-up was 37 (range, 2-84) months. Nine females had a cloaca and the rest had a rectovaginal fistula with an anterior sphincter defect. Eleven (all with anterior tissue) had recurrence of fistula. None with cloaca had recurrence. Eight of 11 recurrences occurred in females who had failed at least one previous repair. No variables that were studied significantly affected recurrence. Median (25th, 75th percentiles) postoperative Wexner incontinence scores for those with and without recurrence were 8 (7, 12) and 5 (2, 6) respectively. CONCLUSIONS: Episioproctotomy is a successful technique for repair of rectovaginal fistula and cloaca. Incontinence score postoperatively were acceptable. It should be considered a first line of surgical treatment in those with a fistula that includes compromise of the anterior sphincter complex.

Surgery for slow transit constipation: are we helping patients?

INTRODUCTION: Long-term outcome after surgery for slow transit constipation is conflicting. The aim of this study was to assess long-term quality of life after surgery. METHODS: The medical records of all patients undergoing colectomy with ileorectal anastomosis between 1983 and 1998 were evaluated. Preoperative, operative, and postoperative details were recorded. A survey was conducted to evaluate current symptoms and health. Quality of life was assessed using the short-form (SF)-36 survey. RESULTS: Sixty-nine (2 male) patients were identified. Five were deceased. Mean age at surgery was 38.6 years (range, 19.7-78.8 years). Median follow-up after surgery was 10.8 years (range, 5.1-18.6 years). Forty-one percent had a family history of constipation. Eleven (16%) had an ileus postoperatively, which responded to medical therapy. One patient had a leak that required temporary diversion. Long-term complications occurred in 32 (46%) patients, which included hernias (3 patients; 4%), pelvic abscess (1 patient; 1.5%), rectal pain (1 patient; 1.5%), small-bowel obstruction (14 patients; 20%, with eight requiring surgery), diarrhea (5 patients; 7%), incontinence (1 patient, 1.5%), and persistent constipation (6 patients; 9%). Fifty-five percent (35/64) responded to a questionnaire. Overall, 25 of 35 (77% of the respondents) stated that surgery was beneficial. Sixty-four percent of patients have semisolid stools, 35% have liquid stools, and 4% reported hard stool. Results of the SF-36 showed the physical component score was comparable with healthy individuals. However, the mental component score was low especially in the areas of vitality (median, 45) and social functioning (median, 37). CONCLUSION: Surgery for constipation is not perfect, and preoperative symptoms may persist after surgery. When assessing long-term quality of life, the mental component of the SF-36 was low compared with the general population, and the physical component was similar. Moreover, because 77% report long-term improvement, surgery is beneficial for appropriate patients.

Analysis of the outcome of ileal pouch-anal anastomosis in patients with Crohn's disease.

PURPOSE: Ileal pouch-anal anastomosis has come to represent the procedure of choice for patients requiring surgery for mucosal ulcerative colitis. In contrast, a proven diagnosis of Crohn's disease is generally held to preclude ileal pouch-anal anastomosis. However, patients with ileal pouch-anal anastomosis for apparent mucosal ulcerative colitis who are subsequently found to have Crohn's disease have a variable course. We reviewed our experience in this scenario to determine whether selected patients with Crohn's disease may be candidates for ileal pouch-anal anastomosis. METHODS: A retrospective review of the prospectively maintained ileal pouch-anal anastomosis database was undertaken to identify patients with a diagnosis of Crohn's disease after ileal pouch-anal anastomosis. Clinical outcome and quality-of-life data were obtained from the database and chart review. End points were the development of recrudescent Crohn's disease, pouch failure, and quality of life and functional outcome at the time of data collection. Differences between groups were calculated using the chi-squared test. Cumulative incidence of recrudescent Crohn's disease and pouch loss were calculated by the Kaplan-Meier method. Factors predictive of development of recrudescent Crohn's disease and pouch loss were examined by univariate analysis. RESULTS: Sixty patients (32 females; median age, 33 (range, 15-74) years) who underwent ileal pouch-anal anastomosis for mucosal ulcerative colitis subsequently had that diagnosis revised to Crohn's disease. Median follow-up of all patients was 46 (range, 4-158) months at time of data collection by which time 21 patients (35 percent) had developed recrudescent Crohn's disease. No pre-ileal pouch-anal anastomosis factors examined were predictors of the development of recrudescent Crohn's disease on univariate analysis. Median follow-up of the latter group was 63 (range, 0-132) months from time of diagnosis, by which time six patients underwent pouch excision and another patient was permanently defunctioned. The overall pouch loss rate for the entire cohort was 12 percent and 33 percent for those with recrudescent Crohn's disease. Median daily bowel movements in those with ileal pouch-anal anastomosis in situ at the time of data collection was 7 (range, 3-20), with 50 percent of patients rarely or never experiencing urgency and 59 percent reporting perfect or near perfect continence. Median quality of life, health, and happiness scores were 9.9 and 10 of 10. CONCLUSIONS: The secondary diagnosis of Crohn's disease after ileal pouch-anal anastomosis is associated with protracted freedom from clinically evident Crohn's disease, low pouch loss rate, and good functional outcome. Such results only can be improved by the continued development of medical strategies for the long-term suppression of Crohn's disease. These data support a prospective evaluation of ileal pouch-anal anastomosis in selected patients with Crohn's disease.
