Both congenital and adult types of hypertrophic stenosis of the pylorus are recognized. The congenital variety has an incidence of 5 per 1000 male births and 1 per 1000 female births in the general population of England (Carter, 1967), but it is less frequent in Negroes and in Asiatics (Donovan and Stanley-Brown, 1962; Swan, 1961). Both environmental and genetic factors seem to operate in the a...

(1) Birth order had no significant influence on the incidence of the disease in boys or girls. Birth order distribution (first born, 42*9%; second, 31-8%, third, 17-9%; fourth, or more 7-4%) did not differ significantly from census data.3 (2) There were significantly more infants with low birth weight (<2500 g) (9-3%) in the group with pyloric stenosis than in the control population (4.9%).4 (3...

In 1978 there was a disproportionate increase in the number of cases of Infantile Hypertrophic Pyloric Stenosis (IHPS) admitted to the Cambridge Military Hospital Aldershot. This increase has not been sustained in subsequent years, although the mean incidence for the period 1979/82 was slightly higher than the preceding years 1975/77. Analysis of the cases occurring in 1978 did not reveal any u...

The first operation for congenital pyloric stenosis in Malta was carried out in 1949. Up to that time it was thought that this disease did not exist locally. However, an increasing number of cases have been diagnosed since then: presumably this is due to more accurate diagnosis and to the fact that doctors have become more aware of its existence. The purpose of this paper is to review the incid...

The most common cause of gastric outlet obstruction in neonates and infants is hypertrophic pyloric stenosis. Pyloric web as a cause of gastric outlet obstruction is relatively rare in children and presents with non bilious vomiting, abdominal pain and failure to thrive. The onset of symptoms is usually late with nonspecific symptoms like vomiting and failure to thrive that seems to be due to n...
