Robotic Heller Myotomy for Advancements in Surgical Management of Achalasia.

ABSTRACT

Achalasia is an esophageal motility disorder. It occurs due to the destruction of nerves in the lower esophageal sphincter (LES), which leads to the failure of the LES to relax. Patients typically complain of dysphagia, chest pain, and regurgitation. They often report drinking liquids with solids intake to help propel food boluses into the stomach. The diagnosis of achalasia is typically confirmed with an esophagogram and a motility study (esophageal manometry). An esophagogram classically shows the bird beak sign with tapering in the distal esophagus. The treatment for achalasia includes both surgical and non-surgical options. Surgical treatment is associated with a lower rate of recurrences, high clinical success rate, and durability of symptom relief. The current gold standard of surgical technique is myotomy, or the dividing of the muscle fibers of the distal esophagus. Surgical myotomy can be accomplished via a laparoscopic or robotic technique; per-oral endoscopic myotomy is a new alternative intervention. Due to the theoretical risk of gastroesophageal reflux following a myotomy, an antireflux procedure is sometimes performed. We reviewed the approach to a robotic heller myotomy for the treatment of achalasia.
