Safety of Endoscopic Sleeve Gastroplasty with a Single-Channel Endoscope

Abstract

Purpose: Less invasive endoscopic bariatric procedures are under development for the management of class I of obesity. The purpose of our study is to evaluate the safety of endoscopic sleeve gastroplasty (ESG) using the new suturing device OverStitch Sx™.

Materials and methods: This is a retrospective single-center study over 191 patients using the ESG under general anesthesia with overnight inpatient observation between January 2019 and December 2020. The analyzed variables were adverse effects and change in body weight at 6 and 12 months of follow-up.

Results: A total of 191 patients underwent ESG for primary obesity. There were 173 female (90.6%) with a mean age of 36.9 years. The mean BMI was 33.7 kg/m² (range: 28.9-54). There were no major intra-procedure adverse events. There were two postprocedural complications (1.04%), a transparietal suturing of falciform ligament which needed laparoscopic exploration for severe abdominal pain and a perigastric collection with antibiotic treatment, both with favorable outcome. Considering the weight loss results, the %TWL recorded was 22.4% for 84 patients (43.9%, 6 months' follow-up) and 18.7% for 69 patients (36.1%, 12 months' follow-up) with the mean EWL of 41.6% and respectively 34.7%. A total of 59 patients (30.9%) were lost follow-up and 12 patients underwent revisional bariatric procedure. According to ASGE definition, 53.8% (n = 71) reached > 25% of EWL.

Conclusion: Endoscopic gastroplasty represents a safe minimal invasive approach with the new device OverStitch Sx™ that can be considered an effective and well-tolerated procedure especially for primary obesity treatment.
