title: Infantile hypertrophic pyloric stenosis: long-term audit from a general surgical unit.
abstract: This article describes a 22 year experience of a general surgical unit in the treatment of infantile hypertrophic pyloric stenosis (IHPS). The hospital course of 229 IHPS patients is reviewed. The male:female ratio was 3.6:1, median age 6 weeks (range 2-26 weeks) with a positive family history in 8.3%. The diagnosis of IHPS was established clinically by palpation of a "pyloric tumour" during a pre operative test meal/clinical examination in 92.6%; in the remainder, the diagnosis was made radiologically. Ramstedt's pyloromyotomy was performed within 5 days of admission in 74% of patients and within 10 days of admission in 89%. The median post-operative hospital stay was 10 days (range 3-60 days). Wound morbidity occurred in 10.0% wound infection (7.3%) and wound dehiscence (2.6%). However, wound morbidity was reduced in the second half of the series, partly by greater utililisation of non-absorbable suture in place of chromic catgut for wound closure. Mucosal penetration was suspected in 14.8% of cases. Repeat pyloromyotomy was necessary in 1.3%. One baby died (0.4%)- this was in the early part of the series and was directly attributable to fluid and electrolyte disorder. We conclude that Ramstedt's pyloromyotomy for infantile hypertrophic pyloric stenosis can be performed with acceptable morbidity and minimal mortality in a general surgical unit.
