pyloromyotomy

Full Definition

A surgical procedure involving the division of the hypertrophied pyloric muscle fibers to relieve gastric outlet obstruction. Most frequently performed as the Ramstedt procedure in infants with hypertrophic pyloric stenosis, where the muscle is divided longitudinally without opening the mucosa. The procedure can be performed through open, laparoscopic, or robotic approaches. Success rates are high, with rapid resolution of projectile vomiting and feeding difficulties.

Usage

Usage note: Often capitalized when referring to the specific Ramstedt technique.
