Congenital (Infantile) Hypertrophic Pyloric Stenosis (IHPS)

Abstract

Background: Infantile hypertrophic pyloric
stenosis affects 0.5 – 3.0 per 1000 live birth and it is
the most common surgical cause of vomiting in
infancy.
Objective: To analyze variable peri-natal factors
that may be involved in the etiology of infantile
hypertrophic pyloric stenosis.
Methods: Over a two year's period, from January
2000 – December 2001, 31 cases of infantile
hypertrophic pyloric stenosis were evaluated for
variable peri-natal risk factors in AL-Eskan central
child teaching hospital for children.
Results: The 31 cases studied were 77.4% males
and 48.4% at three weeks of age. And of all cases,
51.6% were breast fed with a blood group (O) being
the predominant in 54.8%.
Normal vaginal delivery was in 80.6% of cases. All
infants 100% had vomiting, and 48.4% of them
presented with Jaundice and only 16.1% had
constipation. There were no significant correlations
between age and pyloric mass size, age and presence
of jaundice or between pyloric mass size and the
presence of jaundice.
Conclusion: Infantile hypertrophic pyloric stenosis
is a common condition affecting young infants and its
etiology remains unknown, more genetic and
environmental factors should be investigated in the
future.
