Redo ileal pouch-anal anastomosis for malfunctioning pouches-acceptable alternative to permanent ileostomy?
BACKGROUND
Pouch complications after ileal pouch-anal anastomosis (IPAA) can result in morbidity and pouch loss. Recent reports describe success with redo IPAA. This study was conducted to assess the outcome of malfunctioning pouches treated by redo IPAA.


METHODS
All patients undergoing redo IPAA between 1983 and 1999 were identified and clinical records studied. Redo IPAA was defined as an operation for malfunctioning pouch with pelvic dissection and disconnection, pouch revision, and reanastomosis. Analyzed were etiology, presentation, diagnostic modalities, surgical management, pouch loss, and outcome. Follow-up was obtained by telephone or mailed survey.


RESULTS
Between 1983 and 1999, 650 IPAA procedures were performed, 6 (0.9%) of which required redo IPAA. Ten referred patients required redo IPAA. These 16 cases included 7 anastomotic disruptions, 3 pouch-vaginal fistulae, 2 recurrent polyps after stapled IPAA, 2 megapouches, 1 cuff abscess, and 1 straight pullthrough. All patients underwent redo IPAA with pouch salvage 100% in this series. Twelve had the original pouch repaired and 4 new pouches. Six patients (37%) had complications and outcome was acceptable with 7.8 stools per day and nighttime incontinence "rarely" or "never" in 7 patients. Eight described results as "good," 6 as "fair.".


CONCLUSIONS
Redo IPAA can be performed with few complications, an acceptable outcome, and should result in low pouch loss.
