What the trial is, and whether it could suit you

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
