It affects cells both in the myenteric and submucosal plexuses 4.

Hence, functional obstruction develops as a result of a spasm in the denervated colon. It can be anatomically divided into four types according to the length of the aganglionic segment:. It is postulated that hypoganglionosis hirscsprung number of ganglion cells handles intestinal pseudo-obstruction 4.

Findings are primarily those of a bowel obstruction. The affected bowel is of smaller caliber and thus depending on the length of segment affected variable amounts of colonic distension are present.

In protracted cases, marked dilatation can develop, which may progress to enterocolitis and perforation. A carefully performed contrast enema is indispensable in both the diagnosis of Hirschsprung disease but enfermedax in assessing the length of involvement.

It should be noted however that the depicted transition hircshsprung on the contrast enema is not accurate at determining the transition between absent and present ganglion cells.
