Extramucosal pyloromyotomy by laparoscopy.

We performed extramucosal pyloromyotomies by laparoscopy in 20 infants presenting with congenital hypertrophic pyloric stenosis. The surgical technique and precautionary measures, the outcome, and the advantages of this original approach are discussed. In the near future, laparoscopic pyloromyotomy is likely to become a widely used technique.
