Summary. Pyloric stenosis in infants has a typical roentgen‐anatomical appearence. In the manifest stage the canalis egestorius is contracted to a narrow, streak‐like lumen, 2—3 cm in length. The stomach shows stenosal peristalsis, which does not pass beyond the oral limit of the constriction. The duodenal cap is normal in shape and size. The opening time of the stomach is prolonged up to 2 hours (Stage I). After the cessation of the manifest symptoms up to 4 years the opening time is normal and the lumen of the canalis egestorius is somewhat wider with longitudinal rugae Stage II. Later up to 13 years the condition is otherwise unchanged with the exception of the occurrence in some cases of slight peristaltic‐like waves along the canalis egestorius (Stage III). In other cases the canalis egestorius is of normal width and shows normal peristalsis. A clinically symptom‐free member of a pair of twins, the other member with a typical pyloric stenosis, Stage I, showed the roentgen‐anatomical picture of Stage II. The anatomical change consists partly of a thickening of the muscularis propria and partly of the mucosa. In Stages I and II the muscularis propria is unchanged, in Stage III it shows an incipient peristalsis. In Stage I the mucosa almost entirely fills the lumen – manifest symptoms and prolonged opening time. In Stages II and III the swelling of the mucosa is decreased with a canalisation of the lumen and disappearance of the symptoms. The change may be limited to Stage II without any clinical symptoms.
