Outcomes of Acute Pancreatitis in Lean Versus Non-lean Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) Patients: A Nationwide Analysis.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a key contributor to the severity and outcomes of acute pancreatitis (AP). This study compares the clinical outcomes of AP in patients with lean versus non-lean MASLD.

Methods: We identified adult patients hospitalized with AP and a secondary diagnosis of MASLD from the National Inpatient Sample (NIS 2016-2020).
