    Abstract:
    PURPOSE: The aim of this study was to assess outcomes of ileal pouch-anal anastomosis in obese patients compared with a matched cohort of nonobese patients. METHODS: A review of all obese patients who underwent ileal pouch-anal anastomosis from 1998 to 2008 was performed. Obesity was defined as body mass index >or=30 kg/m. A matched control group of patients with body mass index within 18.5 to 25 kg/m was created. Primary end points included operative time, length of hospital stay, operative blood loss, and early (<or=6 wk) and long-term (>6 wk) postoperative complications. RESULTS: Sixty-five obese patients (mean body mass index, 34.3 +/- 0.51 kg/m) underwent proctectomy with ileal pouch-anal anastomosis or proctocolectomy with ileal pouch-anal anastomosis. Mean body mass index of the control group was 22.45 +/- 0.2 kg/m (P < .0001). The most common diagnosis was mucosal ulcerative colitis (84.6%), followed by familial adenomatous polyposis (13.9%) and Crohn's disease (1.5%). The obese population had a higher incidence of cardiorespiratory comorbidities (P = .044), and a trend for steroid and immunosuppressive therapy (P = .06) preoperatively. Obese patients required longer operative time (P = .001) and longer hospital stay (P = .009). Early postoperative complications were comparable (P > .05). Long-term outcomes were also similar, except for a higher incidence of incisional hernia in the obese group (P = .01). CONCLUSIONS: The overall postoperative complication rate in obese patients undergoing ileal pouch-anal anastomosis was similar to a matched nonobese cohort of patients. However, longer operative time, longer length of stay, and a higher rate of incisional hernia were noted in the obese population. Obese patients should be appropriately consulted about these issues before undergoing ileal pouch-anal anastomosis.
