Achalasia, Esophageal clinical trials at UC Irvine

Peroral endoscopic myotomy (POEM) is an effective, minimally invasive treatment for achalasia, offering excellent rates of symptom relief. However, a significant drawback is the high incidence of gastroesophageal reflux disease (GERD) following the procedure. One proposed technical modification, the selective preservation of the sling fibers during gastric myotomy (SFP-POEM), may reduce this risk without compromising efficacy as compared to a conventional POEM procedure, which includes myotomy of the sling fibers. In this study, adults with achalasia will be randomly assigned to receive one of the two POEM technical approaches. Researchers will monitor whether preserving sling fibers reduces the rates of reflux esophagitis (classified as Los Angeles Grade B or higher) on follow-up endoscopy. Participants will be followed for up to 1 year after the procedure.
