Efficacy and Safety of Endoscopic Antral Myotomy as a Novel Weight Loss Procedure (NCT05711758)

Efficacy and Safety of Endoscopic Antral Myotomy as a Novel Weight Loss Procedure: A Pilot Study

๐ŸŸข Recruiting Interventional Protocol ๐Ÿ“Š Observational Clinical Research Sponsor: Christopher C. Thompson, MD, MSc

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

Gastric myotomy has been performed for several years as a means of addressing chronic stenosis after sleeve gastrectomy and treating gastroparesis. The Pylorus Sparing Antral Myotomy (PSAM) technique has the opposite effect by leaving the pylorus intact and extending the myotomy proximally to the distal gastric body. PSAM was initially combined with ESG and shown to delay gastric emptying and provide greater weight loss without impacting tolerability (GCSI score) or the safety profile of the procedure (2 DDW GEM abstracts). PSAM has not been evaluated alone, without concomitant ESG. Since delayed gastric emptying alone is known to promote weight loss, it is thought that PSAM alone (without ESG) may provide similar efficacy, while reducing procedure time and adverse events. There have been no clinical studies that investigate the efficacy of PSAM independent of ESG. This pilot study aims to address this lack of information by evaluating the safety, tolerability, and short-term efficacy of PSAM, in addition to exploring its impact on gastric physiology. This will also provide data that may be used in designing a larger clinical trial.
