I have been diagnosed with "achalasia" and may require an operation. why what how?

See below: Usually a long flexible tube is passed down the throat and in to the esophagus with a video camera so the GI doctor can visualize the problem on a tv screen. It is not really an operation but a procedure. You will receive medicine so you fall asleep during the procedure. The doctor can sometimes inject Botox to help alleviate the problem.

Achalasia: This is a disease where the nerves of the esophagus no longer function to coordinate the muscles to push down food, or send a signal to the lower valve of the esophagus at the entrance to the stomach to open an let the food in. Cause usually unknown. Most effective and most invasive treatment is surgically cutting the muscle of the valve, that can be done laparoscopically or endoscopically (poem).
