PATHOPHYSIOLOGY
Marked hypertrophy and hyperplasia of the 2 (circular and longitudinal) muscular layers of the pylorus occurs, leading to narrowing of the gastric antrum.
The pyloric canal becomes lengthened, and the whole pylorus becomes thickened.
The mucosa is usually edematous and thickened; in advanced cases, the stomach becomes markedly dilated in response to near-complete obstruction.
