- Vertical sleeve gastrectomy (VSG) carries a more than 2-fold higher postoperative risk for acute pancreatitis (AP) than Roux-en-Y gastric bypass surgery (RYGB) or controls.
- Postoperative gallstones, regardless of surgery, were associated with the greatest risk for AP.
Why this matters
- RYGB is the preferred type of bariatric surgery if AP is a concern.
- Both RYGB and VSG patients should be screened for postoperative gallstones.
- Retrospective cohort of morbidly obese patients who underwent VSG (n=205,251), RYGB (n=169,973), or hernia repair (HR) controls (n=16,845) in the 2012-2014 National Readmission Database.
- Primary outcome was rates of AP within 6 months postsurgery vs 6 months presurgery.
- Funding: None.
- AP rates increased post- vs pre-VSG (0.21% vs 0.04%; aOR, 5.16; P<.001 and post- vs pre-rybg aor p=".003)," but not pre-hr.>
- VSG had more than 2-fold greater increase in AP risk than RYGB (aOR, 2.28; P=.03).
- Postsurgery development of AP (vs presurgery) was associated with gallstones:
- VSG: aOR, 85.1 (P<.001 and>
- RYGB: aOR, 46 (P<.001>
- VSG: aOR, 3.76 (P=.001); and
- RYGB: aOR, 6.40 (P=.001).
- Retrospective design.
- Reliance on ICD-9-CM coding.
