Abstract
The diffuse hypertrophy of the lower esophagus is a hypertrophy and hyperplasia of the smooth muscle fibers of the M. [muscularis] propria, together with a distortion of the muscular architecture. The esophagogram reveals an impaired peristalsis and expansive ability of the esophagus lumen. The focal hypertrophy of the pyloric musculature in human adults is a locally circumscribed hypertrophy and hyperplasia of the M. propria. The concentric pattern of the M. propria is no longer maintained. A benign pylorus stenosis with a complete systole and an impaired diastolic dilatation is recognized radiologically. On the basis of these macroscopical, microscopical and radiological findings both lesions differ from the circular pyloric or esophageal stenosis which occurs at the same anatomical sites. Both lesions are different entities.
