Ramstedt pyloromyotomy

Full Definition

A surgical procedure involving division of the hypertrophied circular muscle fibers of the pylorus while preserving the underlying mucosa, used to treat infantile hypertrophic pyloric stenosis. The technique was described by Conrad Ramstedt in 1912 and can be performed via open approach through a right upper quadrant incision or laparoscopically. The goal is to relieve the functional gastric outlet obstruction caused by pyloric muscle hypertrophy.
