The gastrointestinal complications of the Miami Pouch: a review of 77 cases

To describe the gastrointestinal (GI) complications associated with the Miami Pouch (MP), a continent ileocolonic urinary reservoir.

A retrospective chart review of patients who underwent a MP from 1988 to 1997 at the University of Miami, School of Medicine, was employed. Data was analyzed in terms of early and late (beyond 6 weeks) GI complications resulting directly from the operation.

Seventy-seven patients underwent a MP, a form of continent urinary diversion. Seventy-two patients (93.5%) were previously radiated. The perioperative mortality rate was 11.7%. Twenty (26%) patients developed a GI complication (17 late and 3 early), and 5 (6.5%) were directly as a result of the MP. Twelve recto-vaginal and 1 recto-neo-vaginal fistulas were identified. All but one was considered as late. Three (3.9%) patients developed colo-MP fistulas (3, 5, and 14 months). All three patients failed conservative management and required reoperation. Two patients developed enterocutaneous fistulas (3 and 5 months). One patient developed breakdown of the ileotransverse colon anastomosis on postoperative day 12 and required reoperation with bowel resection and an ileostomy. She expired from intraabdominal sepsis. Finally, 1 patient developed short bowel syndrome secondary to an expanding hematoma in the small bowel mesentery.

. The GI complication rate attributed directly to the MP is low (6.5%). Prompt recognition is the key to successful management of these complications. The majority of these complications are considered as late and do not occur in the immediate postoperative period. Conservative management of GI-MP fistulas is not successful and necessitates reoperation.
