Abstract

Endoscopic gastric plication or gastroplasty for morbid obesity is gaining worldwide recognition. Data concerning safety and efficacy are rather scarce. Furthermore, clear guidelines are yet to be established. The objective of this meta-analysis is to update the data and investigate the efficacy and safety of the procedure. An online comprehensive search using Cochrane, Google Scholar, PubMed, Web of Science, and Embase on endoscopic gastric plication was completed. The primary outcome was defined as weight loss at 6 months or more after the procedure. Secondary outcomes were defined as the occurrence of adverse events or complications including insufficient weight loss or regain. I2 statistic was used to define the heterogeneity across studies. Twenty-two cohort studies on 7 different devices met the inclusion criteria, with a total of 2475 patients. The mean baseline BMI was 37.8 ± 4.1 kg/m2 (median 37.9; range 28.0–60.2). Either a transoral endoluminal stapling or (suction based) (full-thickness) stitching and/or anchor device was used to obtain gastric volume reduction and/or alter gastric outlet. The mean follow-up was 13 months (median 12; range 6–24) for the specified outcomes of each study. Two active, FDA-approved devices were taken into account for meta-analysis: Endoscopic sleeve gastroplasty (ESG) and the primary obesity surgery endolumenal (POSE™). Average pooled %EWL at 6 months (p = 0.02) and 12 months (p = 0.04) in favor of ESG was 57.9 ± 3.8% (50.5–65.5, I2 = 0.0), 44.4 ± 2.1% (40.2–48.5, I2 = 0.0), and 68.3 ± 3.8% (60.9–75.7, I2 = 5.8), 44.9 ± 2.1% (40.9–49.0, I2 = N/A) for ESG and POSE respectively. Major adverse events without mortality were described in 25 patients (9 studies, p = 0.63). ESG and POSE are both safe and feasible procedures with good short-term weight loss. ESG seems to be superior in terms of weight loss at this point. Few major adverse events are reported and long-term results are awaited.
