A new study by Nadim Mahmud and team showed that compared to both sleeve gastrectomy and the MOVE! program, Roux-en-Y gastric bypass (RYGB) was linked to a higher incidence of alcohol use disorder (AUD)-related hospitalizations. The findings of this study were published in the Journal of American Medical Association - Surgery.

Roux-en-Y gastric bypass is one of the bariatric surgical methods that has been linked to issues connected to alcohol use. The significant potential confounders of changing body mass index (BMI) or alcohol usage over time, however, have not been well taken into account in prior investigations. Therefore, this study was carried out to compare referral to a weight management program alone with the effects of RYGB, sleeve gastrectomy, or gastric banding on subsequent alcohol use disorder-related hospitalization and all-cause death.

127 Veterans Health Administration medical facilities in the US were included in this cohort research. The study included patients who underwent RYGB, sleeve gastrectomy, or gastric banding or who were referred to MOVE!, a weight management program, and who had a BMI of 30 or higher between January 1, 2008, and December 31, 2021. The BMI is calculated as weight in kilograms divided by height in meters squared. The primary study criteria included RYGB, sleeve gastrectomy, gastric banding, or referral to the MOVE! program. The main result was how long it took until an AUD-related hospitalization occurred after bariatric surgery or a MOVE! Referral.

The key findings of this study were:

1. 1854 patients in total had RYGB, 4211 underwent sleeve gastrectomy, 265 underwent gastric banding, and 1364 were sent to MOVE! In comparison to MOVE! and sleeve gastrectomy, RYGB was linked with a higher risk of AUD-related hospitalization in IPTW Cox regression models that took time-updating alcohol usage and BMI into account.

2. Sleeve gastrectomy and MOVE! did not differ significantly from one another. Although RYGB was linked to a lower mortality risk than MOVE!, this link was weakened over time due to rising alcohol use.

In conclusion, increased alcohol usage reduced the mortality benefit of RYGB, emphasizing the significance of proper patient identification and alcohol-related counseling for patients receiving this treatment.
