Background and aims: About one-third of inflammatory bowel disease (IBD) patients still require surgery. A growing number of them receive anti-tumor necrosis factor (TNF) therapy before surgery. The present meta-analysis studied the risk of postoperative complications in IBD patients treated with anti-TNF. Methods: MEDLINE was searched (up to January 2012) to identify observational studies reporting the prevalence of postoperative complications in IBD patients. The prevalence of overall, infectious, and non-infectious postoperative complications was extracted for all studies, and according to preoperative anti-TNF treatment where reported. Pooled prevalence, as well as odds ratios (ORs), with 95% confidence intervals (Cis) was calculated. Results: The search identified 86 citations. Twenty-one studies, containing 4251 subjects, reported the prevalence of postoperative complications according to preoperative anti-TNF treatment. Pooled prevalence of any postoperative complication was 21%, 35%, and 26% in Crohn's disease (CD), ulcerative colitis (UC) or inflammatory bowel disease unspecified (IBD-U) and IBD, respectively. The prevalence of any postoperative complication was increased in IBD patients who underwent preoperative anti-TNF therapy (OR: 1.25; 95% CI: 1.02-1.53). Pooled prevalence of infectious postoperative complications was 16%, 17%, and 15% in CD, UC/IBD-U and IBD, respectively. The prevalence of infectious postoperative complications was increased in CD patients who underwent preoperative anti-TNF therapy (OR: 1.45; 95% CI: 1.03-2.05). The confounding effect of concomitant therapies could not be studied. Conclusions: Preoperative anti-TNF use slightly increases the occurrence of overall postoperative complications in IBD patients, and particularly infectious complications in CD patients. Postoperative complications are not increased in UC. (C) 2013 European Crohn's and Colitis Organisation. Published by Elsevier B.V. All rights reserved.
