BACKGROUND AND AIM: Roux-En-Y gastric bypass (RYGB) is associated with risk of alcohol use disorder. The impact of RYGB among patients with alcohol-associated liver disease (ALD) remains unknown.
METHODS: A retrospective cohort from National Inpatient Sample (01/2006-09/2015) database on 421,156 admissions with alcohol-associated cirrhosis (AC) was stratified for non-primary discharge diagnosis of previous RYGB. Admissions with RYGB (cases) were matched 1:3 to without RYGB (controls) based on propensity score on demographics, calendar year, socioeconomic status (insurance and zip code income quartile), obesity, diabetes, anxiety, and alcohol use disorder. Primary outcome was concomitant discharge diagnosis of alcoholic hepatitis (AH) or development of acute on chronic liver failure (ACLF).
RESULTS: Of 10,168 admissions (mean age 49 yrs., 75% females, 79% whites), cases (N = 2542) vs. controls had higher prevalence of concomitant AH (18.8 vs. 17%, P = 0.032), hepatic encephalopathy (31 vs. 25%), infection (28 vs. 24%), and grade 3 ACLF (13 vs. 5%), P < 0.001. Conditional logistic regression models showed higher odds for AH, hepatic encephalopathy, and infection among cases. In-hospital mortality of 6.3% (43% in ACLF) was lower in cases, but similar in the sub-cohorts of AH (N = 1768) or ACLF (N = 768). Results were similar in a sensitivity analysis of matched cohort of 2016 hospitalizations (504 cases) with primary discharge diagnosis of AC.
CONCLUSION: Among patients with AC, previous RYGB is associated with increased likelihood of concomitant AH, hepatic encephalopathy, and infection, but similar in-hospital mortality. Prospective studies are needed to validate, determine causality, and understand mechanisms of these findings among patients with alcohol-associated cirrhosis.
