[Roentgenologic diagnosis of congenital hypertrophic pyloric stenosis].

In 1983-1988, in the city of Minsk 196 patients with congenital hypertrophic pylorostenosis (CHRS) were under treatment. The mean CHPS incidence is 1.06 per 1,000 neonates. X-ray examination was performed in 170 cases. CHPS was excluded by error only in one case (0.5%) on day 3 of the disease. In 8 cases, compensated pylorostenosis was diagnosed. It was characterized by proper evacuation from the stomach and positive dynamics of the body weight at the moment of examination. It is suggested that CHPS develops in response to the enhancement of hydrochloric acid secretion. The study points to the high efficacy, simplicity and safety of the method proposed.
