Manometric and functional comparison of ileal pouch anal anastomosis with and without anal manipulation
1Department of Colorectal Surgery, Cleveland Clinic Foundation, Ohio 44195-5044.
Abstract:
We report the results of postoperative physiologic and functional evaluation of 153 patients with ileal pouch anal-anastomosis (IPAA). Ninety-nine patients had anal manipulation for either mucosal proctectomy, transanal placement pursestring suture with stapled IPAA, or handsewn IPAA (manipulation). Fifty-four patients had stapled IPAA with anal pursestrings placed transabdominally without mucosectomy (no manipulation). Patients with transabdominal anal pursestring placement and stapled IPAA without mucosectomy had a higher mean maximum anal resting pressure than patients who had endoanal manipulation. This correlates with improved continence and a reduced need to wear a pad. Avoidance of anal manipulation preserves anal canal resting tone and improves the functional result after IPAA.
