METHODS: This is a systematic review and meta-analysis was performed following the PRISMA guidelines. MEDLINE, Cochrane, EMBASE, and LILACS were searched to identify the studies related to ESG.
RESULTS: Eleven studies with a total of 2170 patients were included. The average BMI pre-ESG was 35.78 kg/m2. Pooled mean %TWL observed at 6, 12, and 18 months was 15.3%, 16.1%, and 16.8% respectively. Pooled mean %EWL at 6, 12, and 18 months was 55.8%, 60%, and 73% respectively. No procedure-related mortality was reported.
CONCLUSIONS: ESG is a safe and effective procedure for primary obesity therapy with promising short- and mid-term results.
