EGPSS for Weight Management in an in Vivo Human Model

Condition(s) studied

Investigational drug(s) / intervention(s)

endoscopic gastric purse-string suturing: A dual-tail endoloop will be introduced into the stomach with endoscopic forceps, and will be secured to the gastric wall using endoscopic clips. An endoscope hook was used to tighten both tails of the endoloop until all the clips converged.

Study summary

ndoscopic bariatric and metabolic therapies (EBMTs) have introduced more convenient, minimally invasive, and safe approaches to weight management. Mucosal ablation of the gastric fundus has been reported to limit fundic expansion and promote satiety; however, ablation can cause perforation, infection, bleeding, and other complications. To restrain fundic expansion while minimizing surgical trauma and preserving reversibility, an endoscopic gastric purse-string suturing (EGPSS) technique was developed to reduce gastric volume. This procedure may be suitable for short-term weight management. Safety and feasibility were demonstrated in a porcine model. The present study will evaluate the feasibility of EGPSS in participants with obesity and assess histological and physiological outcomes.

Eligibility

Primary outcome measure(s)

• Percent Total Weight Loss (%TWL) measured by calibrated digital scale — Baseline and 3 months post-procedure
  Body weight recorded using a calibrated digital scale (kg). %TWL calculated as (baselineweight-follow-upweight)÷baselineweight × 100%. Measurements obtained under fasting conditions, light clothing, no shoes.
