Reoperative abdominal and perineal surgery in ileoanal pouch patients

Complications of the ileal pouch with ileoanal anastomosis are associated with poor function and diminished quality of life; often, these complications may require surgery to salvage the pouch. The aims of this study were to review our experience with reoperative ileoanal pouch surgery and to define any predictors of pouch salvage surgery.

Between 1991 and 1999, the medical records of all patients who underwent reoperative ileoanal pouch surgery for either pouch salvage or pouch excision were reviewed; any minor local procedures were excluded. Successful ileoanal pouch salvage was considered to be an intact and functioning pouch, with acceptable patient satisfaction and good control.

Thirty-two patients underwent reoperative ileoanal pouch surgery, 25 for attempted pouch salvage and 10 for pouch excision (3 patients were included in both groups). Five patients (20 percent) had pouch reconstruction, 1 of which was successful; 8 (32 percent) had pouch advancement, with a 62 percent success rate; and 16 (64 percent) had local perianal procedures for control of perianal sepsis, with a 75 percent success rate (4 of these required further surgery). The overall success rate of ileoanal pouch salvage surgery was 84 percent, with 64 percent of patients having acceptable function. There was no correlation between the number of ileoanal pouch salvage procedures and failure. Four (40 percent) of the 10 patients who had pouch excision were ultimately diagnosed with Crohn's disease.

Ileoanal pouch salvage surgery is often successful and, in motivated patients without Crohn's disease, is worthwhile. Pouch advancement or local perianal repair yielded better results than did pouch reconstruction. Patients diagnosed with Crohn's disease after ileoanal pouch construction may be best suited for pouch excision when complications occur.
