- Bariatric surgery associated with significantly increased odds of new inflammatory bowel disease (IBD).
Why this matters
- Case series had suggested a possible association between bariatric surgery and incident IBD.
- A total of 8968 cases and 42,929 controls were included in the analysis.
- Adjusting for potential confounders, any bariatric surgery (combining recent and past history) was associated with significantly increased odds of new IBD (odds ratio [OR] 1.46).
- Patients who had recent bariatric surgery (within the four years prior to diagnosis) did not appear to be at shorter term risk of IBD (OR 0.95).
- However, past history of bariatric surgery was associated with an increased risk of new onset IBD (OR 1.95). This association was stronger f...
