The use of an omental pedicle graft to prevent small-bowel obstruction after restorative proctocolectomy.
ABSTRACT Small-bowel obstruction remains one of the most frequent complications after restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA). Of particular concern is small-bowel adhesion to the pelvic dead space that causes afferent limb obstruction, sometimes necessitating laparotomy. In this report, we describe a technique using an omental pedicle graft (OPG) to fill the pelvic dead space to prevent small-bowel obstruction and the resulting afferent limb obstruction after IPAA. The OPG is created from the left half of the omentum, while maintaining the blood supply from the left gastroepiploic vessels. The omentum is placed into the pelvis along the left paracolic gutter from where the colon has been resected. It is then passed over the pelvic brim and placed behind and along the bilateral sides of the ileal pouch, filling the space. This modified technique was employed in the treatment of four patients with chronic ulcerative colitis, none of whom developed any signs of small-bowel obstruction.

ABSTRACT: Distal small bowel obstruction following ileal pouch-anal anastomosis (IPAA) can occur secondary to acute angulation or prolapse of the afferent limb at the pouch inlet, namely, afferent limb syndrome (ALS). The aim of this study is to report our experience in diagnosis and management of ALS in patients with IPAA. All patients with ALS after IPAA were identified from prospectively maintained databases. Demographic, clinical, endoscopic, and radiographic features together with its management and outcome were studied. Eighteen patients (12 female) were included. The mean age was 35.6 ± 14.3 years. Most patients presented with intermittent obstructive symptoms. Fifteen patients were diagnosed by pouch endoscopy with features of angulation of the pouch inlet and difficulty in intubating the afferent limb; 12 patients had kinking or narrowing of the pouch inlet identified with abdominal imaging. The median follow-up was 1.3 (range, 0.14-16.1) years. Nine patients underwent empiric balloon dilatation of the afferent limb/pouch inlet. Of nine, four needed repeat dilatations. One patient with repeat dilatation ultimately had pouch excision; another has been scheduled for surgery after failed repeat dilatations. Eight patients underwent surgery, resection of angulated bowel (n = 3), pouchopexy (n = 2), pouch mobilization with small bowel fixation (n = 1), and pouch excision (n = 2). One patient without symptoms did not receive any therapy despite the finding of ALS on pouchoscopy. ALS was characterized by clinical presentation of partial small bowel obstruction, which can be diagnosed by careful pouchoscopy and/or abdominal imaging. Endoscopic or surgical intervention is often needed and surgical therapy appears to be more definitive.Inflammatory Bowel Diseases 06/2011; 17(6):1287-90. · 5.12 Impact Factor

ABSTRACT: To support the small intestine out of the pelvic cavity, many methods have been described to reconstruct the pelvic floor after radical pelvic surgery. I describe a new technique using the rectus abdominis muscles for pelvic floor reconstruction. The posterior rectus sheath and peritoneum are opened. The rectus muscles are exposed at both sides and they are divided between paired clamps at the level of the umbilicus. Then, the rectus muscles are carefully retracted downward, and the edges are sutured posteriorly to the promontorium and laterally around the linea terminalis. This method was used in 11 patients who underwent radical pelvic surgery. Seven of 11 patients had radiation therapy started 4 weeks postoperatively. The patients were followed up for two years. No patient showed any complication such as adhesive obstruction of the bowel or radiation enteritis, even in the patients who underwent radiotherapy. Reconstruction of the pelvic floor using the rectus abdominis muscles after radical pelvic surgery is an easy and safe technique that avoids complications and serves as a barrier to radiation injury. Therefore, we believe that this method is a promising proposal requiring further investigation in a larger number of patients.Diseases of the Colon & Rectum 07/2002; 45(6):836-9. · 3.34 Impact Factor
