Safety and Efficacy of a Novel Flexible Bipolar in POEM

POEM procedures, with or without fundoplication, will be conducted by expert endoscopists who have undergone prior training in the utilization of the ultraslim Speedboat. Incisions, whether anterior or posterior, submucosal tunneling, and myotomy will be performed using the Bipolar Radiofrequency Ablation (RFA) integrated into the device's tip. Additionally, for vessel coagulation, the microwave energy integrated into the device's tip will be employed. Successful myotomy will be confirmed by passage of the endoscope through the esophagogastric junction (EGJ) without restriction.
