Infantile hypertrophic pyloric stenosis: a Dunedin review

Patients who had undergone a Ramstedt pyloromyotomy for infantile hypertrophic pyloric stenosis in Dunedin over a 10 year period to June 1984 were reviewed. Forty-two cases were recorded. More congenital anomalies than expected, a declining rate of wound complications and a high rate of a positive family history were found. The history is reviewed, the data presented and the results discussed.
