title: Laparoscopic extramucosal myectomy with anterior fundoplication (Dor) for esophageal achalasia using intraoperative manometry.
abstract: Laparoscopic extramucosal myectomy with anterior fundoplication according to the Dor technique was performed on a 24-year-old-woman. Intraoperative inflation of a pneumatic balloon made the operative procedures such as extended submucosal dissection quite easy. Intraoperative gastrofiberscopy was useful for confirming that the remaining mucosal layer was not injured after completion of myectomy. Intraoperative manometry confirmed a complete decompression of the high-pressure zone in the lower esophageal sphincter. Complete relief of the symptoms has been recognized for 6 months after operation without any medication. It is considered that these laparoscopic procedures including intraoperative inflation of a pneumatic balloon, gastrofiberscopy, and intraoperative manometry can be used as a standard operation for esophageal achalasia.
