Heller myotomy

Heller myotomy is a surgical procedure in which the muscles of the cardia (lower esophageal sphincter or LES) are cut, allowing food and liquids to pass to the stomach. It is used to treat achalasia, a disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to reach the stomach. Heller myotomy is a surgical procedure in which the muscles of the cardia (lower esophageal sphincter or LES) are cut, allowing food and liquids to pass to the stomach. It is used to treat achalasia, a disorder in which the lower esophageal sphincter fails to relax properly, making it difficult for food and liquids to reach the stomach. It was first performed by Ernst Heller (1877–1964) in 1913. Then and until recently, this surgery was performed using an open procedure, either through the chest (thoracotomy) or through the abdomen (laparotomy). However, open procedures involve greater recovery times. Modern Heller myotomy is normally performed using minimally invasive laparoscopic techniques, which minimize risks and speeds recovery significantly. The 100th anniversary of Heller’s description of the surgical treatment of patients with achalasia was celebrated in 2014. During the procedure, the patient is put under general anaesthesia. Five or six small incisions are made in the abdominal wall and laparoscopic instruments are inserted. The myotomy is a lengthwise cut along the oesophagus, starting above the LES and extending down onto the stomach a little way. The oesophagus is made of several layers, and the myotomy only cuts through the outside muscle layers which are squeezing it shut, leaving the inner mucosal layer intact. This procedure can also be performed robotically.
