Endoscopic sleeve gastroplasty — minimally invasive treatment for non-alcoholic fatty liver disease and obesity

Adequate weight loss can lead to reduction in steatosis, inflammation, and fibrosis in patients with obesity and non-alcoholic fatty liver disease (NAFLD). We evaluated the role of endoscopic sleeve gastroplasty (ESG) in patients with obesity and NAFLD.In this single-center prospective study, consecutive adult patients with NAFLD who underwent ESG between November 2018 and May 2019 were included. The primary outcome was the impact of ESG on hepatic parameters: change in alanine aminotransferase (ALT), hepatic steatosis index (HSI), NAFLD fibrosis score (NFS), fibrosis-4 index (FIB-4), and aspartate aminotransferase (AST)-to-platelet ratio index (APRI) from baseline to 6 and 12 months. Secondary outcomes included change in glycated hemoglobin (HbA1c), percentage weight loss, and safety. Analysis of variance with repeated measures was used for statistical analysis.A total of 26 patients (mean age [SD] 41.5 [9.58] years; 16 females) with mean (SD) weight of 99.43 (21.89) kg at baseline were included. There was significant improvement in ALT (mean ± SD) from baseline of 59.54 ± 17.02 IU/L to 49.50 ± 11.72 IU/L and 48.42 ± 13.22 IU/L at 6 and 12 months (p = 0.001). Mean (SD) NFS was significantly improved from 0.228 (1.00) at baseline to -0.202 (1.16) and -0.552 (1.08) at 6 and 12 months (p 0.001). Mean (SD) HSI, FIB-4, and APRI scores significantly reduced from baseline to 6 and 12 months (p = 0.001). There was 18.07% total body weight loss at 12 months, with significant improvement in HbA1c. There were no major adverse events.ESG is a safe and effective treatment option for patients with NAFLD and obesity causing significant weight loss. Rigorous randomized trials are required to incorporate ESG in NAFLD treatment algorithm.
