Recent results of treatment of infantile hypertrophic pyloric stenosis.

During the five year period December 1980 to November 1985, 106 infants with hypertrophic pyloric stenosis were treated. There were no operative deaths, but two late deaths occurred from associated abnormalities. The combination of preoperative rehydration, skilled anaesthesia, and the use of the Fredet-Ramstedt operation (pyloromyotomy) have virtually eliminated mortality from uncomplicated infantile hypertrophic pyloric stenosis. The most common complications were gastro-oesophageal reflux in 11 (11%), perforation of the duodenal fornix in nine (8%), and wound infection in five (5%); no wound dehisced.
