Pylorospasm

 

a disturbance of the motor function of the stomach accompanied by spasmodic intensification of the tonus of its sphincter. It may accompany such disorders as neuroses and gastric ulcers. Symptoms are pain that disappears after vomiting or irrigation of the stomach; regurgitation and vomiting in the case of newborns; and slight retention of contrast substance in the stomach upon X-ray examination. The disease is treated by means of frequent and light meals, the application of warmth to the stomach, and the administration of antispasmodics.

As the acid flows along the lesser curvature of the stomach toward the pylorus, pylorospasm impairs emptying into the duodenum producing stagnation and injury that is particularly prominent in the antrum.
Sonographically, pylorospasm may resemble PS in that there is some pyloric muscle wall thickening and/or slight elongation of the pyloric channel, but the thickness usually does not exceed 3 mm, and the length of the pylorus usually does not exceed 1.
