Abstract: 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.

Abstract: BACKGROUND & AIMS: Transmural inflammation, a distinguishing feature of Crohn's disease (CD), cannot be assessed by conventional colonoscopy with mucosal biopsy. Our previous ex vivo study of histology-correlated optical coherence tomography (OCT) imaging on colectomy specimens of CD and ulcerative colitis (UC) showed that disruption of the layered structure of colon wall on OCT is an accurate marker for transmural inflammation of CD. We performed an in vivo colonoscopic OCT in patients with a clinical diagnosis of CD or UC using the previously established, histology-correlated OCT imaging criterion. METHODS: OCT was performed in 40 patients with CD (309 images) and 30 patients with UC (292 images). Corresponding endoscopic features of mucosal inflammation were documented. Two gastroenterologists blinded to endoscopic and clinical data scored the OCT images independently to assess the feature of disrupted layered structure. RESULTS: Thirty-six CD patients (90.0%) had disrupted layered structure, whereas 5 UC patients (16.7%) had disrupted layered structure (P < .001). Using the clinical diagnosis of CD or UC as the gold standard, the disrupted layered structure on OCT indicative of transmural inflammation had a diagnostic sensitivity and specificity of 90.0% (95% CI: 78.0%, 96.5%) and 83.3% (95% CI: 67.3%, 93.3%) for CD, respectively. The kappa coefficient in the interpretation of OCT images was 0.80 (95% CI: 0.75, 0.86, P < .001). CONCLUSIONS: In vivo colonoscopic OCT is feasible and accurate to detect disrupted layered structure of the colon wall indicative of transmural inflammation, providing a valuable tool to distinguish CD from UC.

Abstract: OBJECTIVE: Recent experience with surgery for enterocutaneous fistulae (ECF) at a specialist colorectal unit is reviewed to define factors relating to a successful surgical outcome. SUMMARY BACKGROUND DATA: ECF cause significant morbidity and mortality and need experienced surgical management. Previous publications have concentrated on mortality resulting from fistulae, while factors affecting recurrence have not previously been a focus of analysis. METHODS: Records were reviewed of patients who had ECF surgery (1994-2001). Management strategy involved early drainage of sepsis and nutritional support prior to elective ECF repair, with selective defunctioning proximal stoma formation. RESULTS: A total of 205 patients were available (89 males, 43%; median age, 51 years; range, 16-86) years). ECF were related to Crohn's disease in 95, ulcerative colitis in 18, diverticular disease in 17, carcinoma in 25 (16 after radiotherapy), mesh ventral hernia repair in 21, and other causes in 29. Forty-one (20%) had undergone attempted fistula repair at other institutions. Initial management included CT-guided drainage of an intra-abdominal abscess in 23 patients, and total parenteral nutrition in 74 (36%). A total of 203 patients had definitive ECF repair. Forty-four had oversewing or wedge resection of the fistula, and 159 had resection and reanastomosis of the involved small bowel segment or ileocolic anastomosis. Ninety-day operative mortality was 3.5%. A total of 42 (20.5%) patients developed ECF recurrence within 3 months. Multivariate analysis demonstrated that recurrence was more likely after oversewing (36%) than resection (16%, P = 0.006). CONCLUSIONS: A strategy of drainage of acute sepsis, maintenance of nutritional support prior to surgery, and selective use of PS allows for primary closure in 80% of complicated ECF. Resection should be performed when feasible.

Abstract: BACKGROUND AND AIMS: Distinguishing Crohn's disease (CD) from ulcerative colitis (UC) can be difficult. Transmural inflammation, a key feature of CD, cannot be assessed by conventional colonoscopy with biopsy. Optical coherence tomography (OCT) provides high-resolution, cross-sectional images of the gut wall and might become a new diagnostic tool. The aims of this study were to perform histology-correlated OCT on surgical specimens of CD and UC and to determine its diagnostic accuracy. METHODS: Colectomy specimens from patients with a preoperative diagnosis of CD (N = 24) or UC (N = 24) were studied with OCT in the operating room. OCT and histopathology were assessed blindly, and diagnostic accuracy of OCT was assessed. RESULTS: Eight preoperatively identified UC patients (33%) with transmural inflammation on postoperative histology were diagnosed with CD, and all 8 had a disrupted layered structure on OCT, a characteristic feature of transmural disease. Sixteen UC patients (67%) had superficial inflammation on histology; of them, 13 (81%) had an intact layered structure on OCT. All 24 preoperative CD patients had transmural inflammation on histology, and 23 (96%) had a disrupted layered structure on OCT. Of 585 histology-OCT image sets from the 48 patients, 152 sets (26%) had transmural inflammation on histology. The sensitivity and specificity for OCT to detect transmural disease were 86% and 91%, respectively. CONCLUSIONS: Transmural inflammation, as characterized by disruption of the layered structure of colon wall on OCT, is an accurate marker for the diagnosis of CD. Ex vivo OCT predicted transmural inflammation on postoperative histopathology.

Abstract: BACKGROUND & AIMS: Some patients who undergo ileal pouch-anal anastomosis (IPAA) surgery for ulcerative colitis (UC) or indeterminate colitis are subsequently diagnosed with Crohn's disease (CD). Making the diagnosis of CD in patients with IPAA can be difficult, but it is important for prognostic and therapeutic purposes. The aim of this study was to identify diagnostic features of CD in patients with IPAA. METHODS: We evaluated 87 patients who had undergone IPAA for inflammatory bowel disease. Patients were classified as having UC (n = 28), CD (n = 27), or indeterminate colitis (n = 32) based on review of the original colectomy pathology and the postoperative clinical course. Each patient underwent a pouch endoscopy with biopsies of the pouch and afferent limb. Both the endoscopist and pathologist were blinded to the patient's diagnosis. RESULTS: Afferent limb ulcers (ALUs) were seen on endoscopy in 12 of 27 patients with CD (45%) and 4 of 28 patients with UC (14%) (P = 0.019). After excluding patients who had taken nonsteroidal anti-inflammatory drugs (NSAIDs) within the past month, ALUs were found in 7 of 18 patients with CD (39%) and 0 of 17 patients with UC (P = 0.010). Controlling for NSAID use and smoking, the odds ratio for ALUs indicating CD was 4.67 (P = 0.03). In the UC population, ALUs were seen in 4 of 11 patients (36%) who had taken NSAIDs in the past month and 0 of 17 patients who had not taken NSAIDs (P = 0.016). CONCLUSIONS: ALUs seen on endoscopy are suggestive of CD in patients with inflammatory bowel disease who are not taking NSAIDs.

Abstract: PURPOSE: Pouchitis is the most common complication of ileal pouch-anal anastomosis for ulcerative colitis. Our previous study suggested that symptoms alone are not reliable for the diagnosis of pouchitis. The most commonly used diagnostic instrument is the 18-point pouchitis disease activity index consisting of three principal component scores: symptom, endoscopy, and histology. Despite its popularity, the pouchitis disease activity index has mainly been a research tool because of costs of endoscopy (especially with histology), complexity in calculation, and time delay in determining histology scores. It is not known whether pouch endoscopy without biopsy can reliably diagnose pouchitis in symptomatic patients. The aim of the present study was to determine whether omitting histologic evaluation from the pouchitis disease activity index significantly affects the sensitivity and specificity of diagnostic criteria for pouchitis. METHODS: Ulcerative colitis patients with an ileal pouch-anal anastomosis and symptoms suggestive of pouchitis were evaluated. Patients with chronic refractory pouchitis and Crohn's disease were excluded. Patients with pouchitis disease activity index scores of seven or more were diagnosed as having pouchitis. Different diagnostic criteria were compared on the basis of the pouchitis disease activity index component scores. Nonparametric receiver-operating-characteristic curves were used to measure proposed pouchitis scores' diagnostic accuracy compared with diagnosis from the pouchitis disease activity index. The receiver-operating-characteristic area under the curve measured how much these diagnostic strategies differed from each other. RESULTS: Fifty-eight consecutive symptomatic patients were enrolled; 32 (55 percent) patients were diagnosed with pouchitis. With the use of the pouchitis disease activity index as a criterion standard, the use of only symptom and endoscopy scores (modified pouchitis disease activity index) produced an area under the curve of 0.995. Establishing a cut-point of five or more for diseased patients resulted in a sensitivity equal to 97 percent and specificity equal to 100 percent. CONCLUSIONS: Diagnosis based on the modified pouchitis disease activity index offers similar sensitivity and specificity when compared with the pouchitis disease activity index for patients with acute or acute relapsing pouchitis. Omission of endoscopic biopsy and histology from the standard pouchitis disease activity index would simplify pouchitis diagnostic criteria, reduce the cost of diagnosis, and avoid delay associated with determining histology score, while providing equivalent sensitivity and specificity.

Abstract: BACKGROUND: Restorative proctocolectomy (RP) has been the surgical procedure of choice for surgical management of mucosal ulcerative colitis since 1978. This study was undertaken to investigate the clinical presentation and implications of portal vein thrombi (PVT). METHODS: We reviewed all patients undergoing RP in our institution in the 4 years from January 1997 to December 2000. As the diagnosis of PVT was made on computed tomography (CT) scan in all cases, we confined our incidence estimate to those patients having an abdominal CT scan postoperatively. All scans were reviewed by an experienced radiologist. Patient demographics, symptoms, and clinical course were recorded. RESULTS: A total of 702 patients underwent RP, of whom 94 had a CT scan within the postoperative period. PVT was diagnosed in 42 of the 94 patients (45%). PVT was diagnosed at initial reading of the scan in 11 patients, and on review in 31. The indications for CT scan included abdominal pain, fever, leukocytosis, and delayed bowel function. Septic complications of RP caused these symptoms and signs in 45 patients, 20 of whom had PVT. Twenty-two patients were found to have had PVT without evidence of any septic source. CONCLUSION: PVT can be found in a high proportion of patients undergoing abdominal CT scan after RP. It is often associated with pain, fever, nausea vomiting, tenderness, and leukocytosis. This study shows that PVT subtle enough to go undiagnosed has no serious consequences, even when not treated. Also, patients treated with anticoagulation recover completely.
