Infantile hypertrophic pyloric stenosis.

A brief review of the development of the surgical management of infantile hypertrophic pyloric stenosis is made. The incidence, investigation, management and complications of cases treated at the Royal Hospital for Sick Children, Glasgow over a period of six decades is reported. The mortality fell from 59 per cent in 1925 to 0 per cent in 1975. Pyloromyotomy in infants with hypertrophic pyloric stenosis is shown to be a very effective treatment for this potentially lethal condition and must rank as one of the most cost-effective forms of treatment in medical practice.
