Infantile hypertrophic pyloric stenosis in a regional centre.

Abstract

It has been suggested that only specialist paediatric surgeons should manage infantile hypertrophic pyloric stenosis (IHPS). The aim of this retrospective study was to ascertain whether the majority of these infants might be managed in a well-equipped regional centre. Using the Hospital Inpatient Enquiry database, all cases of IHPS within a single administrative health region were identified over a six-year period. A chart review was performed to obtain demographic and clinical information for each patient. Reports from the Central Statistics Office were used to obtain data on population and live births for the region. Seventy patients with IHPS were identified from this region from 1991 to 1996, 63 (90%) of which were treated in the region. Of the remaining seven, four were referred directly to specialised paediatric surgical hospitals because of prematurity (n = 1), low birth weight (n = 1), capillary haemangioma (n = 1) and severe metabolic derangement (n = 1) while three were assessed and treated in general hospitals outside the region. Of the 63 infants undergoing pyloromyotomy in this region, the duodenal mucosa was breached in four (6%); there were wound complications in three (5%); and one required a re-pyloromyotomy. The mean postoperative stay was eight days (range 2-42 days). The majority of infants with IHPS may be safely managed in regional centres with transfer to specialist paediatric centres reserved for 'high risk' cases. The management of IHPS at a regional level has important implications and presents opportunities for surgical training.
