Pre-Procedural Predictors of Successful Endoscopic Sleeve Gastroplasty: A Retrospective Study

Abstract

Objective: Obesity is a major risk factor for the morbidity and mortality of cardiovascular disease and predicts the development of hypertension, diabetes mellitus and other various diseases. Methods: A retrospective study evaluated predictors for higher total body weight loss following endoscopic sleeve gastroplasty (ESG). Adults (>18 years old) with BMI > 30 kg/m2 who underwent ESG from January 2019 to July 2022 were included. Patients under the age of 18 were excluded from the study. Results: This retrospective cohort included 76 patients, of whom 62 women (81.6%) and 14 were men (18.4%) with a mean age of 46.3 ± 10.4. The mean BMI baseline was 36.6 ± 4.21. Out of the included patients, 10% were lost to follow-up at 1 month, 33% at 3 months, 50% after 6 months, and only 30% met 12 months follow-up. During the follow-up period, no mortality was documented. Three major adverse events (3.9%) were documented (one mediastinal abscess, one lower gastrointestinal bleeding and one pulmonary embolism), all of them in female patients. Among the demographic clinical and laboratory data examined, smoking (N = 6, p 50) gained weight earlier, within 3 months, and by 1 year of follow-up almost returned back to their original weight. Females sustained weight loss over 1 year of follow-up compared to males. Patients with lower BMI continued losing weight during the follow-up period (12 months). This study tries to summarize pre-procedural prediction of ESG success.
