The Clinical Relevance of Prior Metabolic and Bariatric Surgery in Alcohol‐Related Liver Disease in a Nationwide Belgian Liver Transplant Population

Year: 2024

Type: article

Abstract: BACKGROUND AND AIMS: Patients with a history of metabolic and bariatric surgery (MBS) are susceptible to developing alcohol use disorder. Outcome after transplantation for alcohol-related liver disease (ALD) has not been studied in-depth. METHODS: We included adult patients who underwent a liver transplantation (LT) in Belgium between 1 January 2013 and 31 December 2022 for ALD. We captured all patients with a history of MBS prior to developing ALD, and included non-MBS patients for comparison. RESULTS: We identified 39 patients who underwent MBS before developing ALD, and included 443 non-MBS patients with an LT for ALD as controls. The median time between MBS and diagnosis of severe liver disease was 7.2 years. MBS patients were 9 years younger at the time of transplantation (p < 0.001). Pre-LT hepatocellular carcinoma was more prevalent in the non-MBS group (p < 0.001), while severe bacterial infections occurred more frequently in those with prior MBS. Importantly, patients with MBS had a lower survival after LT in age- and sex-adjusted Cox regression analysis (HR 2.205, p = 0.023). Liver disease was listed in 70.0% versus 13.3% of patients as the main cause of death. Liver-related mortality was linked to alcohol use relapse post-LT, with significantly more MBS patients experiencing relapse (30.8% vs. 13.3%, p = 0.003). CONCLUSION: Following MBS, excessive alcohol use can progress to end-stage ALD and need for LT. These patients present at a younger age, with more signs of hepatic decompensation, and can be at a higher risk for post-LT mortality, especially liver-related death.
