An endoscopic submucosal myotomy technique may be applied to divide the pyloric sphincter without surgical access. Such endoscopic technique may provide the benefits of a natural orifice procedure, and improve gastric emptying in gastroparetic patients. Gastric Per-Oral Endoscopic Myotomy (G-POEM) is feasible and can be performed by using techniques similar to those of esophageal per-oral endoscopic myotomy. Endoscopists who are experienced in esophageal per-oral endoscopic myotomy should be able to perform G-POEM because both use similar techniques, principles, and equipment.
