Myotomy of the LES decreases the pressure across the gastroesophageal junction and eliminates dysphagia. Unfortunately, myotomy may lead to gastroesophageal reflux; therefore, fundoplication may be coupled with the myotomy at the time of the surgery.

Myotomy can be performed through either transthoracic or transabdominal approaches; however, a transabdominal technique is favored. The laparoscopy and thoracoscopy techniques decrease perioperative morbidity and hospital stay.
