RESUMO
BACKGROUND: Studies were conducted to investigate the outcomes of bariatric surgery (BS) among inflammatory bowel disease (IBD) patients. OBJECTIVES: We aimed to analyze previous literature, comparing the outcomes of BS between IBD and non-IBD patients. SETTING: Not applicable. METHODS: PubMed, Scopus, and Web of Science were searched on 25/9/2023 for comparative studies on outcomes of BS in IBD patients. RevMan Software v5.4 was used to conduct the analysis. RESULTS: Our analysis revealed an insignificant difference in the change of body mass index (BMI) at 1-year post-BS between IBD and non-IBD patients. IBD patients had a higher risk of acute renal failure, hemorrhage, and readmission following BS (RR: 2.16, 95% CI: 1.55-3, RR: 1.57, 95% CI: 1.22-2.04, RR: 1.56, 95% CI: 1.17-2.08, respectively). No significant difference was observed between both groups regarding wounds, leak/intra-abdominal infection, thromboembolic complications, and bowel obstruction. A higher incidence of postoperative complications was seen among IBD patients undergoing RYGB compared with SG (RR: 2.21, 95% CI: 1.43-3.41). There was a significant decline in steroid use following BS in IBD patients (RR: .67, 95% CI: .53-.84). Comparison between UC and Crohn's disease (CD) revealed insignificant differences in treatment escalation or de-escalation. Both IBD and non-IBD patients had similar lengths of hospitalization. CONCLUSIONS: BS is equally effective in IBD and non-IBD patients in terms of weight loss at 1-year follow-up. Nevertheless, IBD patients are at a higher risk of postoperative complications, micronutrient deficiency, and readmission. Both UC and CD reported a decline in steroid use following surgery without a preferential advantage to a particular IBD sub-type.
