Modified Ramstedt's pyloromyotomy for the treatment of infantile hypertrophic pyloric stenosis.

Thirty-seven infants with hypertrophic pyloric stenosis had a modified Ramstedt pyloromyotomy performed. The incidence of postoperative vomiting was low (16%), with no infant suffering sustained vomiting requiring re-exploration for incomplete pyloromyotomy. The modified Ramstedt's pyloromyotomy is a simple procedure and may confer an advantage in the postoperative course of the recovering infant.
