Pronunciation: HELL-er my-OT-oh-mee
Surgical division of the lower esophageal sphincter muscle to treat achalasia.
Full Definition
A surgical procedure that involves dividing the muscle fibers of the lower esophageal sphincter (LES) to relieve dysphagia in patients with achalasia. The myotomy can be performed via open, laparoscopic, or thoracoscopic approach. It is often combined with a fundoplication to prevent postoperative gastroesophageal reflux. The procedure was first described by Ernst Heller in 1913.
