Salvage reoperation for complications after ileal pouch-anal anastomosis

Surgical revision may be possible in patients with a poor outcome following ileal pouch-anal anastomosis (IPAA), using either a transanal approach or a combined abdominoperineal approach with pouch revision and reanastomosis.

Sixty-four patients underwent revisional surgery. The indication for salvage was sepsis in 47 patients, mechanical dysfunction in ten, isolated complications of the residual glandular epithelial cuff in three and previous intraoperative difficulties in four patients.

A transanal approach was used in 19 patients and a combined abdominoperineal procedure in 45. Six of the latter had pouch enlargement and 25 received a new pouch. During a mean(s.d.) follow-up of 30(25) months, three patients required pouch excision because of Crohn's disease. Two patients had poor continence after abdominoperineal surgery. At last follow-up 60 (94 per cent) of 64 patients had a functional pouch. Half of the patients experienced some degree of daytime and night-time incontinence, but it was frequent in only 15 per cent. Of 58 patients analysed, 27 of 40 who had an abdominoperineal procedure and 13 of 18 who had transanal surgery rated their satisfaction with the outcome as good to excellent.

Surgical revision after failure of IPAA was possible in most patients, yielding an acceptable level of bowel function in two-thirds of patients.
