This is an operation for achalasia cardia, a condition in which the muscle in the lower oesophagus fails to relax and therefore hinders the passage of food and fluid into the stomach. Treatment with Botox injections or balloon dilatation of the affected part of the oesophagus can be attempted but are often short-lived and surgery is frequently required as a more lasting solution.

Intake of food should become more comfortable soon after surgery and a near-normal diet can be maintained.
