Abstract
BACKGROUND

There is a scarcity of evidence and systematic reviews on endoscopic gastroplasty (EG) compared to other management options for the treatment of obesity.

AIM

To assess the published meta-analyses through a systematic review approach and provide further insight into the current status of available evidence through a critical appraisal.

METHODS

PubMed/MEDLINE, Scopus, Embase and Cochrane Library were searched from inception to November 2022. The meta-analyses that compared the efficacy and safety of EG to other interventions were considered for this overview. The outcomes of interest were total body weight loss (TBWL), excessive weight loss, and average weight loss along with occurrence of adverse effects. Methodological quality, heterogeneity, and limitations were also reviewed.

RESULTS

A total of six meta-analyses out of 364 records were considered for this review with a major contribution from the United States. Overall methodological quality of included studies were moderate to good. EG treatments were significantly better in terms of TBWL, excessive weight loss, and average weight loss. However, there was no significant difference between endoscopic transoral outlet reduction and full-thickness suturing plus argon plasma mucosal coagulation. Lack of comparative studies and randomized trials, lack of long-term follow-up, reporting bias, selection bias, lack of control groups, and considerable level of heterogeneity were the major limitations in the available evidence.

CONCLUSION

Though EG was significantly effective for treatment of obesity, there is limited comparative evidence on this topic. High-quality well-controlled evidence is required to strengthen the current evidence base on EG treatment for obesity.

Keywords: Body weight; Endoscopy; Evidence-based practice; Obesity; Safety

Core Tip: Endoscopic gastroplasty treatments were significantly better in reducing total body weight, excessive weight, and average weight among obese population. No significant difference between endoscopic transoral outlet reduction and full-thickness suturing plus argon plasma mucosal coagulation. Lack of comparative, long-term follow-up and randomized studies, reporting and selection bias, high level of heterogeneity were the major limitations in the currently available meta-analyses.
