Background: Infliximab (IFX) is a breakthrough treatment for refractory Crohn's disease (CD) whose effect on postoperative complications of CD remains controversial. The purpose of this study was to conduct a meta-analysis examining the effect of IFX on postoperative complications of CD.
Methods: We searched "PubMed," "EMBASE," and "Cochrane Library" databases from inception of each database until March 2018. All eligible articles were screened according to the inclusion criteria. The cumulative overall, major, minor, infectious, noninfectious, surgical, and medical complications, as well as reoperation, readmission, and mortality of CD patients who received IFX and underwent ileocolonic resection were extracted and analyzed using Review Manager 5.3. The random effects model was used to calculate the odds ratio (OR) and 95% confidence interval (CI).
Results: A total of 18 nonrandomized controlled trial studies, with 1407 patients who received IFX and 4589 patients who did not were identified. The incidence of complications was 9.38%-60.56% in the IFX group and 12.73%-53.85% in the control group. Overall, major, minor, infectious, noninfectious, surgical, and medical complications could be assessed in 16, 12, 11, 14, 12, 12, and 11 studies, respectively. There were no statistically significant differences between the 2 groups for any complication (P > 0.05, all comparisons). Reoperation (P = 0.70), readmission (P = 0.22) and mortality (P = 0.86) showed no significant difference between the 2 groups. Subgroup analysis showed that complications were not significantly different among the countries represented in the studies.
Conclusions: Based on this analysis, there does not appear to be an association between preoperative IFX treatment and postoperative complications of CD; IFX appears relatively safe for preoperative use in the treatment of CD. 10.1093/ibd/izy246_video1izy246.video15813237394001.
