RESUMEN
BACKGROUND: The prospect of pouch failure needs to be considered when evaluating the management strategy for patients who may be candidates for an ileo anal pouch. An ability to predict the likelihood and timing of failure preoperatively may influence surgical decision making. OBJECTIVE: The aim of this study was to define a preoperative prognostic model for ileoanal pouch failure. DESIGN: A novel random forest methodology was used to evaluate the prognostic significance of 21 preoperative potential risk factors for pouch failure. A forest of 3000 random survival trees was grown to estimate pouch failure for each patient and to identify important risk factors that maximize survival prediction. SETTINGS: This study took place at a tertiary referral department at a major academic medical center. PATIENTS: Patients undergoing an ileoanal pouch at this institution between 1983 and 2008 were included. MAIN OUTCOME MEASURES: The primary outcome measured was pouch survival. RESULTS: Between 1983 and 2008, 3754 patients underwent ileoanal pouch. Type of resection (total proctocolectomy vs completion proctectomy), type of anastomosis (stapled vs mucosectomy), patient diagnosis (mucosal ulcerative colitis and others vs Crohn's disease) and diagnosis of diabetes had the strongest effect on pouch survival. Predicted survival was worse for completion proctectomy (HR, 1.44; 95% CI, 1.08-1.93), Crohn's disease (HR, 2.37; 95% CI, 1.48-3.79), handsewn anastomosis (HR, 1.72; 95% CI, 1.23-2.42), and diabetes (HR, 2.31; 95% CI, 1.25-4.24). Pouch survival was worse for the oldest group of patients. LIMITATIONS: This study was limited by its retrospective nature. CONCLUSION: Random forest techniques applied to a large number of patients undergoing the ileoanal pouch identify factors associated with pouch failure. Attention directed at these factors may improve outcomes for these patients.

AIM: We reviewed the functional results and quality of life (QOL) of patients who had had an ileoanal pouch (IPAA) for at least 15 years. METHOD: Retrospective analysis was undertaken of data accrued prospectively into a pouch database since 1983. Patients who had retained an IPAA for at least 15 years were identified. Trends in IPAA function and QOL of the patients were determined over a time-period of 15 years after formation of the IPAA. Data were compared for patients who were < 35, 35-55 and > 55 years of age when the IPAA was formed. RESULTS: Three hundred and ninety-six of a total of 3276 patients in the database (53% men, median age 36 years and median follow-up 17.1 years) underwent IPAA with at least 15 years of follow-up. The final pathology was ulcerative colitis in 78%; 66.4% of patients had a restorative proctocolectomy, 91.4% underwent temporary diversion, 59% had a J-pouch configuration and 63.1% a stapled anastomosis. The frequency of bowel movements remained the same over the follow-up period. There was an increase in the incidence of incontinence and urgency after 15 years with no significant change in dietary, social, work and sexual restrictions during follow-up. Patients in all three age groups experienced deterioration in pouch function at 15 years of follow up compared with the function at 5 years. The QOL of the patients remained high and stable. CONCLUSION: There is a deterioration of pouch function after 15 years, irrespective of the age of the patient when the IPAA was formed. Despite this, QOL appears to be high for all patients who retain their pouch.

BACKGROUND: The influence of function on quality of life after primary restorative proctocolectomy (RPC) was determined with the aim of developing a pouch functional score. METHODS: The Cleveland Global Quality of Life (CGQL) score was determined in 4013 patients undergoing RPC between 1977 and 2005 (mean(s.d.) follow-up 7.0(5.1) years; 13 105 follow-up episodes). Linear regression analysis was used to identify independent symptom domains of function as possible predictors of quality of life to develop and validate a pouch functional score. RESULTS: CGQL scores at 1, 5, 10, 15 and 20 years were 85.0, 87.5, 87.5, 85.0 and 82.5 respectively (P = 0.001). On multivariable analysis, the symptom domains of stool frequency (24 h, nocturnal), urgency, incontinence and medication (antidiarrhoeals, antibiotics) were independently associated with CGQL (P < 0.001). The beta coefficients within each symptom domain were then adjusted to create a scale of 0-30 for practical use, the Pouch Functional Score (PFS), which correlated with the CGQL score (r(s) = -0.47, P < 0.001). CONCLUSION: Stool frequency, urgency, incontinence and need for medication are major determinants of quality of life following RPC. The PFS demonstrated good correlation with CGQL.

BACKGROUND: Diagnosis and management of chronic antibiotic-refractory pouchitis and Crohn's disease of the pouch can be challenging. Pyloric gland metaplasia is a histological feature indicative of chronic mucosal inflammation. Its value in diagnosis and prognosis of pouch disorders has not been investigated. AIM: To assess the prevalence, diagnostic and prognostic value, and risk factors of pyloric gland metaplasia in pouch patients. METHODS: Patients were identified from our prospectively maintained Pouchitis Database. Pouch biopsy specimens were re-reviewed for pyloric gland metaplasia and other histological features. Two cohorts of patients were studied: a historical cohort (n = 111) and the second, a validation cohort (n = 100). Univariate and multivariate analyses were performed to assess risk factors for pyloric gland metaplasia. RESULTS: The prevalence of pyloric gland metaplasia in the historical cohort and validation cohort was 45 (40.1%) and 24 (24.0%), respectively. The sensitivity and specificity of pyloric gland metaplasia for the diagnosis of chronic antibiotic-refractory pouchitis or Crohn's disease were 70.7% and 92.5%, respectively, for the first cohort and 39.0% and 86.4%, respectively, for the 2nd validation cohort. In multivariate analysis of the first cohort, patients with refractory pouchitis or Crohn's disease were 28 times (95% CI, 7.3-107.1) more likely to have pyloric gland metaplasia than those with a normal pouch or irritable pouch syndrome. The factor of refractory pouchitis or Crohn's disease remained in the model for the 2nd validation cohort with odds ratio of 4.58 (95% CI, 1.6-13.4). CONCLUSIONS: Pyloric gland metaplasia is associated with diagnosis of chronic antibiotic-refractory pouchitis or Crohn's disease of the pouch and appears to be a specific marker for both disease entities.

AIM: The aim of this study was to determine preoperative clinical factors associated with subsequent diagnosis revision to Crohn's disease (CD) following total proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) or indeterminate colitis (IC) patients. METHOD: Presumed UC and IC patients undergoing IPAA from a large single-institution prospective database with change of diagnosis to CD were identified and compared with patients without diagnosis change. RESULTS: A total of 2814 patients (47% male, median age 37 years) with presumed UC (85%) or IC (15%) underwent primary IPAA. At a median follow up of 9.6 years, 184 (7%) had the diagnosis revised to CD from histopathological examination of the colectomy specimen immediately in 97 (53%) or at a median interval of 36 months in 87 (47%). CD and UC/IC patients had had a similar operative technique, length of stay and 30-day morbidity. The postoperative CD diagnosis was associated with a preoperative diagnosis of IC (P < 0.0001) and perianal fistula (P = 0.002). Patients with a delayed diagnosis of CD were associated with a 3-stage procedure (P < 0.0001, OR = 2.8) (95% CI = 1.8-4.4), colonic stricture (P = 0.04, OR = 2.9 [95% CI = 1.1-7.4]), perianal fistula (P = 0.02, OR = 2.9 [95% CI = 1.2-7.2]), oral ulceration (P = 0.009, OR = 3.8 [95% CI = 1.2-9.6]) and younger age (P < 0.0001, OR = 0.048 [95% CI = 0.011-0.19]). CONCLUSION: A few patients having IPAA for presumed UC/IC were subsequently diagnosed to have CD which was associated with perianal fistula and the diagnosis of postoperative preoperative IC. The delayed diagnosis of CD was associated with a three-stage procedure, colorectal stricture, anal fissure, mouth ulceration and younger age.

BACKGROUND: The Turnbull-Cutait abdominoperineal pull-through procedure (T-C) is used as a last resort to avoid permanent diversion in patients with complex anorectal conditions. The aim was to evaluate short- and long-term outcomes after T-C. METHODS: Patients undergoing T-C from 1996 to 2007 were reviewed retrospectively in terms of demographics, diagnosis, indications and postoperative complications. Patients were contacted to obtain functional outcomes using a standardized questionnaire. Functional outcomes were compared with those in a matched group of patients undergoing handsewn coloanal anastomosis (CAA) for rectal cancer. RESULTS: Sixty-seven patients (40 men) underwent T-C. Postoperative complications included stricture in 11 patients (16 per cent), fistula in five (7 per cent), prolapse of the colon in five (7 per cent) and leak in two (3 per cent). Mean follow-up was 5.6 (s.d. 3.2) years. The operation failed in 17 patients (25 per cent). Among 44 patients (66 per cent) who completed questionnaires, faecal (P = 0.121) and urinary (P = 0.073) incontinence, and sexual function (P = 0.063) were comparable to those in patients who had CAA. CONCLUSION: T-C is an option for patients with complex anorectal conditions that might otherwise require permanent diversion. Functional outcomes are comparable to those of CAA.

PURPOSE: This study was designed to investigate sexual and urinary dysfunction in women who underwent rectal cancer excision, and the influence of tumor and treatment variables on long-term outcomes. METHODS: Data were prospectively collected on 295 women who underwent rectal cancer excision at a tertiary referral colorectal center from 1998 to 2006. Sexual and urinary function was assessed preoperatively and at intervals up to five years after surgery. Functional outcomes were assessed by using univariate and multivariate regression analysis, chi-squared test for trend, or Kruskal-Wallis test. RESULTS: The mean age of the patients was 60.9 years. Anterior resection was performed in 222 patients (75.2 percent) and abdominoperineal resection in 73 patients (24.7 percent). Patients who underwent abdominoperineal resection were less sexually active (25 vs. 50 percent; P = 0.02) and had a lower frequency of intercourse than anterior resection patients at one year after surgery (anterior resection, 3 (0-5) (median interquartile range); abdominoperineal resection 0 (0-4); P = 0.029). The frequency of intercourse improved over time for abdominoperineal resection (4 months, 0 (0-0) median interquartile range; 5 years, 3 (0.25-4) median interquartile range; P = 0.028). Abdominoperineal resection was associated with increased dyspareunia (odds ratio, 5.75; 95 percent confidence interval (CI), 1.87-17.6; P = 0.002), urinary urgency (odds ratio, 8.52; 95 percent CI, 2.81-25.8; P < 0.001), incontinence (odds ratio, 2.41; 95 percent CI, 1.11-5.26; P = 0.026), poor stream (odds ratio, 5.64, 95 percent CI, 2.55-12.5; P Asunto(s)

RESUMEN
BACKGROUND: Crohn's disease (CD) of the pouch can develop in patients with ileal pouch-anal anastomosis (IPAA). Scant data are available on the treatment of this disease entity. AIM: To evaluate efficacy and safety of adalimumab in treating CD of the ileal pouch. METHODS: From June 2007 to June 2008, 17 IPAA patients with inflammatory (n = 10), fibrostenotic (n = 2) or fistulizing (n = 5) CD of the pouch treated with adalimumab were evaluated. Inclusion criteria were CD of the pouch who failed medical therapy and were otherwise qualified for permanent pouch diversion or excision. All qualified patients received the standard dosing regimen of subcutaneous injection adalimumab (160 mg at week 0, 80 mg at week 1, and 40 mg every other week thereafter). Complete clinical response was defined as resolution of symptoms. Partial clinical response was defined as improvement in symptoms. Endoscopic inflammation before and after therapy was recorded, using the Pouchitis Disease Activity Index (PDAI) endoscopy subscores. RESULTS: The median age was 36 years with 12 patients (70.6%) being male. At 4 weeks, seven patients (41.2%) had a complete symptom response and 6 (35.3%) had a partial response. There was also a significant improvement in the PDAI endoscopy subscores at week 4 (P < 0.05). At the last follow-up (median of 8 weeks), eight patients (47.1%) had a complete symptom response and 4 (23.5%) had a partial response. Four patients (23.6%) developed adverse effects. Three patients (17.7%) eventually had pouch failure after failing to respond to adalimumab therapy. CONCLUSION: Adalimumab appeared to be well-tolerated and efficacious in treating CD of the pouch in this open-labelled induction study.

Restorative proctocolectomy with ileal pouchanal anastomosis (IPAA) is the surgical treatment of choice for complicated ulcerative colitis. Development of ileal pouch-related cancer is a rare event and usually occurs in association with backwash ileitis or chronic pouchitis. We report a case of adenocarcinoma at the inlet of an ileal pouch in a 68-year-old Caucasian male, 14 years after restorative proctocolectomy for ulcerative colitis in the absence of severe chronic pouchitis or backwash ileitis. The operative technique is described, with a review of the literature on ileal pouch cancer.

PURPOSE: This study was designed to evaluate the yield and cost of fever evaluations in average-risk inpatients after elective colorectal surgery. METHODS: A 12-month, retrospective study was performed on patients who developed a postoperative fever > or = 38 degrees C after elective colorectal surgery. A positive fever evaluation was defined as a blood culture, urine culture, chest x-ray, or abdominal CT result that led to a change in patient management. Logistic regression, Fisher's exact test, and chi-squared test were used; odds ratios were calculated. RESULTS: Of 133 patients, 26 percent had a positive evaluation. Blood culture, urine culture, chest x-ray, and CT were positive in 3, 8, 7, and 46 percent, respectively. Risk factors for a positive fever evaluation were temperature > or = 38.5 degrees C, fever evaluation after postoperative Day 6, and a clinical manifestation of systemic inflammatory response syndrome other than fever (all, P < 0.01). The cost per positive fever evaluation for the entire group, patients with 2 risk factors, or patients with 3 risk factors was $5,600, $4,200, and $2,140, respectively. CONCLUSIONS: The current approach to fever evaluation after elective colorectal surgery is low yield and costly. High fever, late postoperative fever, and systemic inflammatory response syndrome are risk factors for a positive fever evaluation after colorectal surgery.

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.

OBJECTIVE: The choice of ileal pouch reservoir has been a contentious subject with no consensus as to which technique provides better function. This study aimed to compare short- and long-term outcomes of three ileal reservoir designs. METHOD: Comparative studies published between 1985 and 2000 of J, W and S ileal pouch reservoirs were included. Meta-analytical techniques were employed to compare postoperative complications, pouch failure, and functional and physiological outcomes. Quality of life following surgery was also assessed. RESULTS: Eighteen studies, comprising 1519 patients (689 J pouch, 306 W pouch and 524 S pouch) were included. There was no significant difference in the incidence of early postoperative complications between the three groups. The frequency of defecation over 24 h favoured the use of either a W or S pouch [J vs S: weighted mean difference (WMD) 1.48, P < 0.001; J vs W: WMD 0.97, P = 0.01]. The S pouch was associated with an increased need for pouch intubation (S vs J: OR 6.19, P = 0.04). The use of a J pouch was associated with a significantly higher prevalence of use of anti-diarrhoeal medication (J vs S: OR 2.80, P = 0.01; J vs W: OR 3.55, P < 0.001). CONCLUSION: All three reservoirs had similar perioperative complication rates. The S pouch was associated with the need for anal intubation. There was less frequency and less need for antidiarrhoeal agents with the W rather than the J pouch.

OBJECTIVE: To evaluate long-term health-related quality of life, for single-staged and staged resections following reversal, for complicated diverticular disease. PATIENTS AND METHODS: Between 1981 and 2003, 188 patients undergoing single stage (n = 158) or staged resection (n = 30) completed the SF-36 questionnaire. Health-related quality of life (HRQL) was compared between the two groups and the US normal population based on the eight domains of the SF-36. HRQL analysis was also performed at various time intervals. The effect of age and postoperative complications on HRQL was also determined. Functional and postoperative outcomes were also assessed. RESULTS: The single and staged resection groups differed in the presence of comorbidity, degree of peritoneal contamination and operative urgency. No difference in functional outcomes or HRQL was found, even after analysing time-interval subgroups. Social functioning and general health was substantially worse in both groups when compared to US norms. Ageing was found to significantly reduce physical functioning (P < 0.001) and physical and emotional role limitations (P < 0.001 for both). Post-operative complications significantly reduced scores when compared to patients without complications, for physical functioning (63.57 vs 78.7, respectively; P < 0.001), physical role limitation (80.65 vs 86.9, respectively; P < 0.001) and bodily pain (66.67 vs 74.81, respectively; P < 0.01). CONCLUSIONS: No significant difference in long-term HRQL was found in patients undergoing single staged or staged resection for complicated diverticular disease. There was significant impact of ageing and postoperative complications on physical health. Prospective studies that include pre-operative data on HRQL are required to compare the two operative techniques, with emphasis on quality of life of patients left with a permanent stoma.

Collagenous colitis is characterised by watery diarrhoea, normal colonic mucosa on endoscopy, diffuse colitis with surface epithelial injury, and a distinctive thickening of the subepithelial collagen table on histology. Some patients can develop medically refractory collagenous colitis, in which case they may require surgical intervention. This is the first report of collagenous pouchitis in a collagenous colitis patient with proctocolectomy and ileal pouch-anal anastomosis. A patient with medically refractory collagenous colitis who underwent a total proctocolectomy and ileal pouch-anal anastomosis was sequentially evaluated with an endoscopy and histology of the colon, distal small intestine, and ileal pouch. A 58-year-old female had a 10-year history of collagenous colitis before having a total proctocolectomy and ileal pouch-anal anastomosis for medically refractory disease. The histologic features of collagenous colitis were present in all colon and rectum biopsy or resection specimens, but were absent in the distal ileum specimen. The post-operative course was complicated by persistent increase of stool frequency, abdominal cramps, and incontinence. A pouch endoscopy was performed 3 years after ileal pouch-anal anastomosis which showed the histologic features of collagenous colitis in the ileal pouch, collagenous pouchitis, while the pre-pouch neo-terminal ileum had no pathologic changes. After antibiotic therapy, the histologic changes of collagenous pouchitis resolved. This is the first reported case of collagenous pouchitis. Since the abnormal collagen table and its associated features were only present in the pouch and absent in the neo-terminal ileum, and the patient had histologic improvement after antibiotic therapy, it would suggest that faecal stasis and bacterial load may play a role in the pathogenesis.

BACKGROUND: Surgery for familial adenomatous polyposis (FAP) aims to minimize cancer risk while providing good functional outcome. Colectomy with ileorectal anastomosis and proctocolectomy with ileal pouch-anal anastomosis both offer this, but there is no clear consensus about which is better. METHODS: This is a meta-analysis of comparative studies published between 1991 and 2003 reporting early and late postoperative adverse events, functional outcomes and quality of life. RESULTS: Twelve studies containing 1002 patients (53.4 per cent ileal pouch, 46.6 per cent ileorectal anastomosis) were identified. Bowel frequency (weighted mean difference 1.62 (95 per cent confidence interval (c.i.) 1.05 to 2.20)), night defaecation (odds ratio (OR) 6.64 (95 per cent c.i. 2.99 to 14.74)) and use of incontinence pads (OR 2.72 (95 per cent c.i. 1.02 to 7.23)) were significantly less in the ileorectal group, although faecal urgency was reduced with the ileal pouch (odds ratio 0.43 (95 per cent c.i. 0.23 to 0.80)). Reoperation within 30 days was more common after ileal pouch construction (23.4 versus 11.6 per cent; OR 2.11 (95 per cent c.i. 1.21 to 3.70)). There was no significant difference between the techniques in terms of sexual dysfunction, dietary restriction, or postoperative complications. Rectal cancer was a diagnosis only in the ileorectal group (5.5 per cent). CONCLUSION: Ileal pouch and ileorectal anastomoses have individual merits. Further research is needed to determine which most benefits patients with FAP.

BACKGROUND AND METHODS: The comparative benefits and drawbacks of straight coloanal anastomosis (CAA), colonic J-pouch and coloplasty anastomosis after anterior resection are uncertain. Studies published between 1986 and 2005 of colonic J-pouch versus transverse coloplasty or straight CAA were analysed. Endpoints included postoperative complications, and functional and physiological outcomes measured within 6 months, 1 year and 2 years or more after the procedure. A random-effect model was used to aggregate the study endpoints and assess heterogeneity. RESULTS: Thirty-five studies containing 2240 patients (1066 straight CAA, 1050 J-pouch and 124 coloplasty) were included. There was no significant difference in postoperative complications between the three groups. There was a significant reduction in the frequency of defaecation per day by 1.88, 1.35 and 0.74 motions at the three time intervals in the J-pouch group compared with the straight CAA group. Faecal urgency was less prevalent in patients with a J-pouch than those with a straight CAA (odds ratio 0.27 at 6 months or less and 0.21 at 1 year). There was no difference in functional outcome between J-pouch and coloplasty anastomosis. CONCLUSIONS: The colonic J-pouch provided functional benefits over straight anastomosis with no increase in postoperative complications. Coloplasty appeared to have similar benefits but further studies are required for validation.

BACKGROUND: Laparoscopic repair (LR) of rectal prolapse is potentially associated with earlier recovery and lower perioperative morbidity, as compared with open transabdominal repair (OR). Data on the long-term recurrence rate and functional outcome are limited. METHODS: Perioperative data on rectal prolapse in relation to all LRs performed between December 1991 and April 2004 were prospectively collected. The LR patients were matched by age, gender, and procedure type with OR patients who underwent surgery during the same period. Patients with previous complex abdominal surgery or a body mass index exceeding 40 were excluded from the study. Data on recurrence rate, bowel habits, continence, and satisfaction scores were collected using a telephone survey. RESULTS: A total of 111 patients (age, 56.8 +/- 18.1 years; female, 87%) underwent attempted LR. An operative complication deferred repair in two cases. Among the 111 patients, 42 had posterior mesh fixation, and 67 had sutured rectopexy (32 patients with sigmoid colectomy for constipation). Eight patients (7.2%) had conversion to laparotomy. Matching was established for 86 patients. The LR patients had a shorter hospital stay (mean, 3.9 vs 6.0 days; p < 0.0001). The 30-day reoperation and readmission rates were similar for the two groups. The rates for recurrence requiring surgery were 9.3% for LR and 4.7% for OR (p = 0.39) during a mean follow-up period of 59 months. An additional seven patients in each group reported possible recurrence by telephone. Postoperatively, 35% of the LR patients and 53% of the OR patients experienced constipation (p = 0.09). Constipation was improved in 74% of the LR patients and 54% of the OR patients, and worsened, respectively, in 3% and 17% (p = 0.037). The postoperative incontinence rates were 30% for LR and 33% for OR (p = 0.83). Continence was improved in 48% of the LR patients and 35% of the OR patients, and worsened, respectively, in 9% and 18% (p = 0.22). The mean satisfaction rates for surgery (on a scale of 0 to 10) were 7.3 for the LR patients and 8.1 for the OR patients (p = 0.17). CONCLUSIONS: The hospital stay is shorter for LR than for OR. Both functional results and recurrent full-thickness rectal prolapse were similar for LR and OR during a mean follow-up period of 5 years.

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.

BACKGROUND: Management of antibiotic-dependent pouchitis is often challenging. Oral bacteriotherapy with probiotics (such as VSL #3) as maintenance treatment has been shown to be effective in relapsing pouchitis in European trials. However, this agent has not been studied in the US, and its applicability in routine clinical practice has not been evaluated. AIM: To determine compliance and efficacy of probiotic treatment in patients with antibiotic-dependent pouchitis. METHODS: Thirty-one patients with antibiotic-dependent pouchitis were studied. VSL #3 is a patented probiotic preparation of live freeze-dried bacteria. All patients received 2 weeks of ciprofloxacin 500 mg b.d. followed by VSL #3 6 g/day for 8 months. Baseline Pouchitis Disease Activity Index scores were calculated. Patients' symptoms were reassessed at week 3 when VSL #3 therapy was initiated and at the end of the 8-month trial. Some patients underwent repeat pouch endoscopy at the end of the trial. RESULTS: All 31 patients responded to the 2-week ciprofloxacin trial with resolution of symptoms and they were subsequently treated with VSL #3. The mean duration of follow-up was 14.5+/-5.3 months (range: 8-26 months). At the 8-month follow-up, six patients were still on VSL #3 therapy, and the remaining 25 patients had discontinued the therapy due to either recurrence of symptoms while on treatment or development of adverse effects. All six patients who completed the 8-month course with a mean treatment period of 14.3+/-7.2 months (range: 8-26 months) had repeat clinical and endoscopic evaluation as out-patients. At the end of 8 months, these six patients had a mean Pouchitis Disease Activity Index symptom score of 0.33+/-0.52 and a mean Pouchitis Disease Activity Index endoscopy score of 1.83+/-1.72, which was not statistically different from the baseline Pouchitis Disease Activity Index endoscopy score of 2.83+/-1.17 (P=0.27). CONCLUSION: This study was conducted to evaluate bacteriotherapy in routine care. The use of probiotics has been adopted as part of our routine clinical practice with only anecdotal evidence of efficacy. Our review of patient outcome from the treatment placebo showed that only a minority of patients with antibiotic-dependent pouchitis remained on the probiotic therapy and in symptomatic remission after 8 months.
