Abstract
BACKGROUND AND AIMS: Postoperative intra-abdominal septic complications [IASCs] are the most feared risks of surgery for Crohn's disease[CD]. The risk factors for IASCs still remain controversial. The aim of this study was to assess the risk factors for IASCs in CD patients undergoing abdominal surgery. METHODS: MEDLINE, Cochrane Library, and EMBASE were searched to identify observational studies reporting the risk factors for IASCs in CD patients. A meta-analysis was conducted to investigate the impact of various risk factors on IASCs in CD. The GRADE [Grading of Recommendations Assessment, Development and Evaluation] approach was used for quality assessment of evidence on outcome levels. RESULTS: This review included 15 studies evaluating 3807 patients undergoing 4189 operations. The meta-analyses found that low albumin levels (odds ratio [OR]: 1.93; 95% confidence interval [CI]: 1.362.75), preoperative steroids use [OR: 1.99; 95% CI: 1.54-2.57], a preoperative abscess [OR: 1.94; 95% CI: 1.263.0], previous surgery history [OR: 1.50; 95% CI: 1.151.97] may be risk factors for IASCs. There were no associations between anastomosis methods [OR: 0.94; 95% CI: 0.58-1.53], biologics therapy [OR: 1.29; 95% CI: 0.792.11], and immunomodulator use [OR: 1.07; 95% CI: 0.661.73] with the risk of IASCs. Due to observational design, the quality of evidence was regarded low or moderate for these risk factors by the GRADE approach. CONCLUSIONS: This meta-analysis provides some evidence that steroids use, previous surgical history, a preoperative abscess, and low albumin levels may be associated with higher rates of IASCs in CD. Knowledge about those risk factors may influence treatment and procedure-related decisions, and possibly reduce the ss rate.
