Two-time perforation of the ileal J-pouch 6 and 18 years after restorative proctocolectomy and ileal pouch–anal anastomosis for familial adenomatous polyposis: a case report

Background Perforation of the ileal J-pouch after restorative proctocolectomy and ileal pouch–anal anastomosis are extremely rare. There has been no report of perforation of the ileal J-pouch occurring twice over several years. We report the first case of perforation at 6 and 18 years following restorative proctocolectomy. Case presentation The patient was a 52-year-old man who underwent a two-stage restorative proctocolectomy with a hand-sewn ileal J-pouch anal anastomosis due to familial adenomatous polyposis and sigmoid colon cancer at 34 years of age. At the age of 40, he underwent ileal pouch resection at its blind end, abdominal drainage, and anastomotic dilatation. The patient had a perforation of the blind end of the ileal J-pouch from increased intraluminal pressure, with anastomotic stricture and pervasive peritonitis. The patient had no symptoms for a few years; however, 18 years after the initial surgery and 12 years after the first perforation, the patient presented with severe abdominal pain. Computed tomography demonstrated pneumoperitoneum; accordingly, laparotomy was performed. Upon opening the abdominal cavity, contaminated ascites and inflammatory changes were documented involving the ileum. A 2-mm perforation involving the blind end of the ileal J-pouch was also observed and repaired, followed by temporary loop ileostomy creation. Postoperative endoscopy revealed an ulcer in the ileal J-pouch and a stricture located directly at the anastomosis. Conclusions The blind end of the J-pouch repeatedly perforated over the years due to recurrent anastomotic stricture. Regular surveillance is, therefore, considered necessary for the release of stricture, maintenance of anastomotic patency, and prevention of ileal J-pouch perforation.

Association of ileocolic pedicle division with postoperative complications after restorative proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis

Background When performing a restorative proctocolectomy (RPC) with an ileal pouch-anal anastomosis (IPAA), it is common practice to divide the ileocolic artery (ICA) if the patient has a tumor or dysplasia, or in order to gain sufficient length to secure a tension-free anastomosis. However, it is unclear whether there is an association between division of the ICA and the rate of postoperative complications. Methods We retrospectively analysed all patients with ulcerative colitis who underwent RPC and IPAA in our department between January 2010 and December 2016. These were divided in two groups, with regard to the ICA being preserved (PRE group) or divided (DIV group). Complications such as stenosis or leakage of the IPAA, perianal fistulas, abscess formation within the lesser pelvis and pouchitis were analysed and compared between both groups. Results We identified 130 patients meeting the study inclusion criteria, 49 patients in the PRE and 81 patients in the DIV group. No statistical significance was observed in IPAA leakages (p = 0.71), anastomotic strictures (p = 0.33), fistulas (p = 0.19) and pouchitis (p = 0.72). Abscess formation frequency was similar in both groups (p > 0.99). Moreover, short-term (p = 0.53) and long-term complications (p = 0.11) were similar in both groups. A higher conversion rate was observed in obese (p = 0.006) and male (p = 0.02) patients. Within the entire study population, fistulas and IPAA leakages were associated with a higher rate of anastomotic strictures (p = 0.008 and p = 0.02 respectively). Conclusion Our data suggest similar IPAA related complications after either division or preservation of the ICA. Further trials are required in order to examine the trends observed in this study.

Restorative Proctocolectomy: When to Propose and When to Avoid

Restorative proctocolectomy with ileal pouch-anal anastomosis (RPC-IPAA) is a surgical procedure performed when excising the entire colon and rectum is need and reconstitution of the intestinal transit through an ileal pouch is made with anastomosis to the anus. It is mainly used to treat patients with familial adenomatous polyposis (FAP) and ulcerative colitis (UC). It is a complex surgery with potential complications, and the functional outcomes can be worse over time. So, it is essential to select the appropriate patient, proceed to a correct surgical technique, and know-how to deal with and solve the main ileal pouch complications. This chapter intends to be a reflection on this subject.
