👉 Myotomy is a surgical procedure that involves reducing or removing part of the esophagus (throat) through a surgical incision. This can be done in order to treat various conditions such as reflux disease, ulcers, and other health issues related to the esophagus. Myotism is when the muscles of the esophagus become weakened due to damage from surgery or infection, which may lead to difficulty swallowing or pain.
