Abstract    Objective    To identify the perioperative complication incidence and its risk factors in patients underwent ileal/ileocecal resection for chronic radiation enteritis (CRE) with small bowel obstruction. Methods    Univariate and multivariate analysis of a retrospectively gathered database between June 2001 and December 2011 in Department of General Surgery, Nanjing General Hospital of Nanjing Military Command PLA were performed on a cohort of patients (n=158) underwent ileal/ileocecal resection for CRE obstruction at a single institution. Altogether, we analyzed 33 potential risk factors to identify significant influence on the postoperative outcome. Results    Overall and major morbidity rates were 57.0% (90 patients) and 28.5% (45 patients), respectively. The mortality rate was 1.9% (3 patients). Univariate analysis determined that ASA score of not less than 3, anemia, low platelet level, long operation time, intraoperative transfusion, presence of radiation uropathy and proctitis and experience of surgeons were important risk factors for Grade Ⅲ-Ⅴ morbidity. Multivariate analysis found ASA score of not less than 3, anemia, intraoperative transfusion, low platelet level, radiation uropathy and surgeon’s experience as independent risk factors for Grade Ⅲ-Ⅴ  morbidity. Conclusion    The current study provides the first evidence of predictive risk factors for postoperative morbidity of ileal/ileocecal resection for CRE.
