Abstract
Background:
The need for surgical management of severe obesity in the context of inflammatory bowel disease (IBD) is becoming an increasingly common clinical scenario, yet has been met with significant reservation due to the paucity of current data from which to inform evidence-based clinical decision making. The aim of our study was to perform a systematic review to characterize and evaluate the safety and efficacy of bariatric surgery in IBD patients.
Methods:
A medical librarian developed and executed comprehensive searches on November 2, 2021. The population of interest was adult subjects (>18 years) diagnosed with inflammatory bowel disease (IBD) undergoing any type of bariatric surgery. Meta-analysis was used to evaluate outcomes using RevMan 5.4.1.
Results:
A total of 330 687 patients were identified within the 11 studies included. Within all included studies there were 1595 patients with IBD. Patients had a mean weighted age of 46.0, with a female predominance (n = 1287, 80.7%). The mean duration of follow up was 39.7 months. Metabolic and anthropometric outcomes were only reported in noncomparative studies evaluating only patients with IBD, limiting the ability to complete meta-analysis. Meta-analysis revealed that IBD was associated with increased rates of postoperative complications (RR 2.14; 95% CI 1.87-2.44; P < .00001) in comparison to controls without IBD.
Conclusion:
While bariatric surgery presents an effective weight loss option for patients with IBD, these patients are associated with higher rates of postoperative complications. This work highlights the need to better delineate the effect of bariatric procedures for patients with IBD with respect to both metabolic and IBD-related outcomes.
