Heller myotomy for achalasia. From the open to the laparoscopic approach.

The last three decades have witnessed a progressive evolution in the surgical treatment of esophageal achalasia, with a shift from open to a minimally invasive Heller myotomy. The laparoscopic approach is currently the standard of care with better short-term outcomes and similar long-term functional results when compared to open surgery. More recently, the laparoscopic single-site approach and the use of the robot have been proposed to further improve the surgical outcome in achalasia patients.
