Pyloric stenosis in adults: A clinical and radiological study of 100 consecutive patients.

EDITORIAL SYNOPSIS The causes of obstruction in 100 cases diagnosed clinically as 'pyloric stenosis' showed that the majority of cases were duodenal ulcer stenosis, with prepyloric carcinoma as second in frequency. In the earlier stages the obstruction is overcome by hyperactivity of the gastric muscle but later on muscular failure occurs with gastric atony and retention of food. This is reversible and should be corrected before surgical treatment.
