We sought to characterize the changes in esophagogastric junction (EGJ) distensibility during Heller Myotomy with Dor fundoplication using the EndoFLIP device. Intraoperative distensibility measurements on 14 patients undergoing Heller myotomy with Dor fundoplication were conducted over an 18-month period. Minimum esophageal diameter, cross-sectional areas, and distensibility index were measured at 30 and 40 mL catheter volumes before myotomy, postmyotomy, and following Dor fundoplication. Distensibility index is defined as the narrowest cross-sectional area divided by the corresponding pressure expressed in mm/mm Hg. Heller myotomy was found to lead to significant changes in the distensibility characteristics of the EGJ. Minimum esophageal diameter and EGJ distensibility increased significantly with Heller myotomy.
