Myotomy
ICD-10-PCS0D787ZZ
ICD-9-CM42.42

Myotomy is a surgical procedure that involves cutting a muscle to relieve constriction, often performed in the gastrointestinal or urological systems. The procedure can alleviate symptoms caused by muscle-related functional obstructions, particularly in cases of achalasia, a disorder that affects the esophagus. Myotomies may be performed using open, laparoscopic, or endoscopic techniques, depending on the location and condition being treated. Common types include the Heller myotomy, used to treat esophageal achalasia, and pyloromyotomy, commonly performed in infants with pyloric stenosis.
