Tubulovillous adenoma in an Indiana pouch urinary diversion managed by endoscopic resection.

Abstract: We present a case of a tubulovillous adenoma in an Indiana pouch managed by endoscopic resection. A 66-year-old male underwent a cystectomy with creation of an Indiana pouch urinary diversion for invasive small cell carcinoma of the bladder. Seven years following his initial surgery, the patient noted several episodes of gross hematuria. The evaluation revealed a 2.5 cm tubulovillous adenoma with high-grade dysplasia within the Indiana pouch. The patient had significant comorbidities precluding an open operative procedure. He underwent en endoscopic resection of the tumor, and subsequently has been managed with surveillance pouchoscopy, biopsies, and fulguration every 3 months.

An unusual haemorrhagic complication of an anastomotic leak and a novel method of controlling the haemorrhage

Abstract: Introduction Restorative proctocolectomy (RP) is undertaken for patients with familial adenomatous polyposis (FAP) and ulcerative colitis, but is associated with a risk of anastomotic leak. Case history A 20-year-old male with a family history of FAP had a RP with a double-stapled J-pouch and covering loop ileostomy. At ileostomy reversal 21 months later, he presented with significant anal bleeding. He proceeded to theatre for endoscopy. Pouchoscopy showed a pouch full of blood and a foreign object trapped in a diverticulum. The foreign object (an undigested tablet) was removed with grasping forceps and the bleeding spot identified. Hemospray® (Cook Medical, Winston-Salem, NC, USA) was deployed in the bleeding cavity to enable immediate control of haemorrhage. Recovery was uneventful and he was discharged home 72 hours later. Conclusions This case: (i) demonstrates a successful and novel method of controlling haemorrhage not amenable to use of conventional haemostatic mechanisms; (ii) highlights the poten...

Clinical factors associated with the development of Crohn's disease in inflammatory bowel disease-unclassified patients undergoing ileal pouch-anal anastomosis

Abstract: BACKGROUND Patients with inflammatory bowel disease-unclassified (IBDU) undergoing ileal pouch-anal anastomosis (IPAA) are at the risk of developing Crohn's disease (CD) after surgical procedure. In these patients, a clinically centered set of preoperative risk factors has not been prospectively defined. We report a single-center analysis of clinical factors associated with the development of CD after IPAA. METHODS Consecutive IBDU patients undergoing IPAA were identified. The diagnosis of IBDU was based on the presence of atypical disease distribution, presence of granulomas on endoscopic biopsy, and/or perianal disease. The diagnosis of CD after IPAA included the presence of afferent limb inflammation on pouchoscopy in the absence of nonsteroidal anti-inflammatory drug use and/or the development of pouch fistulizing disease more than 3 months after ileostomy closure. RESULTS Of the 149 study patients, 33 (22%) were diagnosed with CD after IPAA at a median of 37 months (interquartile range, 11-83 mo) after ileostomy closure. CD was diagnosed by mucosal inflammation above the pouch (n = 23; 70%), pouch fistulizing disease (n = 4; 12%), anorectal septic complications (n = 2; 6%), or the presence of ≥2 of the above complications (n = 4; 12%). The sole clinical predictor for the development of CD after IPAA was younger age at disease onset even after controlling for relevant clinical factors in a multivariate analysis. The odds of developing CD increased by 4% for each year that IBDU was diagnosed at a younger age. CONCLUSIONS Younger age at disease onset is the only clinical factor associated with the development of CD after IPAA for IBDU. Patients with IBDU undergoing IPAA with young age at disease onset should be counseled about the potentially higher risk of developing CD.
