What this trial studies

This observational cohort collects retrospective clinical data and includes one prospective 5-year visit to document long-term weight outcomes after ESG performed with the OverStitch endoscopic suturing system. Eligible adults had a primary ESG at least five years before enrollment, had a BMI of 30–50 kg/m2 at the time of that procedure, and completed early follow-up visits including a 1-year visit and annual follow-ups between years 2–4. Study sites are in Illinois, Texas, and New South Wales and the sponsor is Boston Scientific Corporation. No experimental treatments are given; investigators will analyze weight-change trajectories and related clinical data to characterize the durability of weight loss after ESG.

Who should consider this trial

Good fit: Ideal candidates are adults who received a primary OverStitch ESG at least five years ago, had a BMI of 30–50 at the time of the procedure, completed required early follow-ups, and are willing to attend a 5-year visit and provide medical records.

Not a fit: People considering ESG but who have not had the procedure, those treated with a different device or without the required follow-up data, are unlikely to benefit directly from this observational follow-up.

Why it matters

Potential benefit: If successful, the results could clarify how durable weight loss is after ESG and help patients and clinicians make informed long-term treatment choices.

How similar studies have performed: Shorter-term studies (1–2 years) of ESG have shown meaningful weight loss, but robust five-year outcome data are limited, so this follow-up provides relatively novel long-term information.
