Abstract
Abdominal ultrasonic examination was performed in 8 infants with hypertrophic pyloric stenosis, and in 23 control patients of the same age. The average anteroposterior diameter of the pylorus in children with hypertrophic pyloric stenosis measured 17 mm (range 15-20 mm), and 9.6 mm (range 6-12 mm) in the control group. The statistical difference was highly significant (p less than 0.001). In addition, delayed gastric emptying and retroperistalsis of the stomach were demonstrated. The sonographic findings of hypertrophied pylorus correlated well with roentgenologic results and were confirmed during following operation. Abdominal sonography is a rapid, safe and non-invasive method for the identification of hypertrophic pyloric stenosis.
