Endoscopic Evaluation of the Hypertrophic Pyloric Stenosis in Adult

Abstract

Endoscopic evaluation of the hypertrophic pyloric stenosis in the adult was discussed on 10 of 19 cases in Japan including our 4 cases. Nine diffuse forms (by Skoryna) showed “protruded lesion, deformity, irregularity and stenosis of the pyloric ring, pyloric narrowing unaffected by anticholinergic agents, and irregular mucosal folds adjacent to the pylorus”. One focal form showed only a tumor like lesion on the lesser curvature of the pylorus. Associated gastric ulcers should be carefully observed. Frontal view type upper GI endoscope should be used for the diagnosis of the hypertrophic pyloric stenosis in the adult.
