Bariatric Surgery May Improve Outcomes for Obese Patients with Inflammatory Bowel Disease
New research reveals that bariatric surgery can significantly improve inflammatory bowel disease outcomes in obese patients, offering a promising integrated treatment approach.
Recent research suggests that bariatric surgery could play a beneficial role in managing inflammatory bowel disease (IBD) among patients with obesity. A comprehensive study published online on July 22 in BJS Open examined the impact of surgical weight loss procedures on IBD outcomes. The study was led by Dr. Erik Stenberg from Örebro University in Sweden and involved a nationwide cohort of adult Swedish patients with both obesity and IBD, spanning from 2007 to 2020.
The research included 798 patients, with half undergoing bariatric surgery—either sleeve gastrectomy or Roux-en-Y gastric bypass—and the other half serving as controls. Over the follow-up period, those who had surgery experienced significantly fewer events indicative of IBD worsening, such as hospitalizations, initiation of corticosteroids or immunomodulators, and major disease-related surgeries. Specifically, the primary composite endpoint occurred in 201 patients with surgery compared to 226 without, reflecting a hazard ratio of 0.66, which signifies a 34% reduction in risk.
Importantly, both types of bariatric procedures showed a trend toward reducing IBD complications, but the statistically significant results were primarily associated with Roux-en-Y gastric bypass. These findings indicate that bariatric surgery might be a useful intervention not only for weight loss but also for reducing the severity and progression of IBD in obese patients.
This research underscores the potential dual benefits of bariatric surgery for individuals suffering from obesity and IBD, illuminating new avenues for comprehensive treatment strategies. For more detailed information, refer to the original study in BJS Open at this link.
