Objective To determine risk factors for postoperative infectious complications for small bowel obstruction.Methods Retrospective analysis the clinical data from small bowel obstruction patients who admittedto our hospital between January 2006 and December 2012 who receiving surgical treatment.The independent risk factors for infective complications were detected by logistic analysis.Results One hundred and fifty-four patients received surgery for small bowel obstruction with infection rate 27.9％.Logistic analysis revealed that older people(≥65 years) (OR 6.71,95％ CI 3.15-16.33),intraoperative bowel rupture (OR 2.71,95％ CI 1.19-7.25),delay surgery(≥72 h)(OR 11.33,95％CI4.62-20.20) and operation time(≥180 min) (OR 2.90,95％ CI 1.26-9.83) were the independent risk factors for postoperative infective complications.Conclusions Postoperative infections were the common complications after surgery for small bowel obstruction.Early surgery,intraoperative soft operation to prevent bowel rupture may be effective measures to reduce postoperative infection.
