Roux-en-Y Gastric Bypass Is Associated With Increased Hazard for De Novo Alcohol-related Complications and Liver Disease.
Journal Article (Journal Article)
GoalThe goal of this study was to determine if bariatric surgeries are associated with de novo alcohol-related complications.
BackgroundBariatric surgery is associated with an increased risk of alcohol use disorders. The effect of bariatric surgeries on other alcohol-related outcomes, including liver disease, is understudied.
Materials and methodsUsing the IMS PharMetrics database, we performed a cohort study of adults undergoing bariatric surgery or cholecystectomy, excluding patients with an alcohol-related diagnosis within 1 year before surgery. The primary outcome was any alcohol-related diagnosis after surgery. We fit a multivariable Cox proportional hazards model to determine independent associations between bariatric surgeries [Roux-en-Y gastric bypass (RYGB); adjustable gastric band; sleeve gastrectomy] versus cholecystectomy and the development of de novo alcohol-related outcomes. We further fit complication-specific models for each alcohol-related diagnosis.
ResultsRYGB was significantly associated with an increased hazard of any de novo alcohol-related diagnosis [adjusted hazard ratio (AHR)=1.51, 95% confidence interval (CI): 1.40-1.62], while adjustable gastric band (AHR=0.55, 95% CI: 0.48-0.63) and sleeve gastrectomy (AHR=0.77, 95% CI: 0.64-0.91) had decreased hazards. RYGB was associated with a 2- to 3-fold higher hazard for alcoholic hepatitis (AHR=1.98, 95% CI: 1.17-3.33), abuse (AHR=2.05, 95% CI: 1.88-2.24), and poisoning (3.14, 95% CI: 1.80-5.49).
ConclusionsRYGB was associated with higher hazards of developing de novo alcohol-related hepatitis, abuse, and poisoning compared with a control group. Patients without a history of alcohol use disorder should still be counseled on the increased risk of alcohol use and alcohol-related complications, including alcohol-related liver disease, following RYGB, and should be monitored long term for the development of alcohol-related complications.
