Total proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the standard surgical treatment for patients with ulcerative colitis (UC). The purpose of this study was to investigate the long-term functional outcomes and quality of life (QOL) associated with hand-sewn and stapled IPAA. Ninety-one patients with UC had undergone IPAA using hand-sewn anastomosis with mucosectomy (32 patients) or stapled anastomosis (59 patients) from January 1988 to May 2010. Patients were evaluated according to patient characteristics, postoperative complications, functional outcomes and QOL. The QOL of patients were evaluated using the Medical Outcomes Study Short Form 36 (SF-36) and the Inflammatory Bowel Disease Questionnaire (IBDQ). Numbers of patients with colorectal cancer or dysplasia were significantly greater in the hand-sewn IPAA group (P , 0.01). These patients had longer disease durations and were older (both P , 0.01). There was no difference in the incidence of complications between the groups, except for a greater incidence of postoperative anal fistula in the stapled group (P ¼ 0.03). In the early postsurgery period, both the frequency of bowel movements and the rate of soiling were significantly higher in the hand-sewn group, but in a later period, there was no difference in these events .3 years after surgery. The SF-36 and IBDQ results were similar in the two groups, indicating that hand-sewn and stapled IPAA result in similar QOL in the late postoperative Corresponding author: Hiroaki Ishii, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-0033, Japan. Total proctocolectomy with ileal pouch-anal anastomosis (IPAA), which was first described in 1978 by Parks and Nicholls, 4 has become established as the standard surgical treatment for patients with UC. The problems with IPAA are that the excision close to the anal sphincter may result in impaired anal function that may cause neurologic damage to the rectum, in turn resulting in urinary and sexual dysfunction. The anastomosis of ileal pouch leads to diarrhea and frequent bowel movements that may adversely affect patients' quality of life (QOL). Two different anastomotic techniques are generally used in IPAA: handsewn anastomosis with mucosectomy, which removes all rectal mucosa to the dentate line, and stapled anastomosis (Fig. 1). Patients who undergo hand-sewn anastomosis are thought to develop impaired anal function and QOL more than that in patients who underwent stapled anastomosis.Although some reports have suggested that the stapled anastomosis provides a better functional outcome than the hand-sewn anastomosis, 5-7 no report has investigated the difference between a hand-sewn IPAA and a stapled IPAA with regard to QOL using validated questionnaires.We reviewed postoperative complications and evaluated postoperative function both objectively and subjectively. We compared long-term functional outcomes and QOL between these two techniques, using the Medical Outcomes Study Short Form 36 (SF-36), 8 which is a validated generic QOL instrument, and the inflammatory bowel di...
