title: Idiopathic Hypertrophie Pyloric Stenosis : Our Experience.
abstract: BACKGROUND
  A typical infant with idiopathic hypertrophic pyloric stenosis is described as a male child, first in the order of birth with a positive family history. However our experience suggests otherwise which is presented in this report. Methods : A retrospective analysis of medical records of 8 infants, who were diagnosed to be suffering from idiopathic hypertrophic pyloric stenosis and subjected to surgical treatment, was undertaken.
  
  
  RESULTS
  There were 5 (62.5%) males and 3 (37.5%) females. There was no family history and only one child (12.5%) was first born in the order of birth. One infant was preterm and one case (12.5%) had associated congenital anomaly (single kidney). Definitive diagnosis was established in 6 (75%) babies at admission whereas, other 2 cases (25%) required further evaluation. All the infants were in a state of moderate dehydration and in a varying state of hypochloremic alkalosis. The pH and serum chloride levels ranged from 7.52 to 7.67 and 86-94 mmol/L respectively. All were subjected to traditional Ramstedt's pyloromyotomy after having undergone vigorous correction of fluids and electrolytes for 24-48 hours. Intraoperatively, there was one iatrogenic mucosal perforation, which was closed with an omental patch. Postoperative feeding was initiated 12 hrs after surgery in 6 (75%) babies.
  
  
  CONCLUSIONS
  Our series suggests a clinical profile of hypertrophic pyloric stenosis in our subset of patients which is different from what is described in literature.
