Real-time ultrasonogram was performed in 31 Pt. With CHPS, who was admitted at the pediatric department of Wonkwang University hospital from January 1991 to June 1993. Those who had positive results of pyloric volume for diagnosis of CHPS and were confirmed by surgery. The results were at follows, 1) The average ultrasonographic measurements of pyloric muscle thickness, pyloric diameter, pyloric length were 4.9¡¾1.09mm, 14.42¡¾2.69mm, 19.17¡¾2.37mm, and pyloric volume was 3.26¡¾1.39mm. 2) The diagnostic reliabilities with the ultrasonographic measurements of muscle thickness(>4mm), pyloric diameter(>12mm) and pyloric length(>15mm) by Stunden's criteria in 31 cases were compared, which were not significant difference among them. 3) In ultrasonographic measurements of 31 cases for diagnosis of CHPS, positive results with 3 parameters were 80.6%, and with 2 parameters and double tract signs were 87.1%. So, we conclude pyloric volume greater than 1.4ml was the most reliable parameter, which was satisfied 100% with diagnosis of CHPS.
Key Words: Congenital hypertrophic pyloric stenosis, Ultrasonogram, Pyloric volume
