Question

which of the following is the congenital disease of the intestine that is associated with an absence of the parasympathetic ganglia cells in the rectum?
meconium ileum
meckels diverticulum
congenital pyloric stenosis
hirschsprung disease

Explanation:

To solve this, we analyze each option:

• Meconium ileum: Involves meconium blockage, not ganglia absence.
• Meckel’s diverticulum: A remnant of the vitelline duct, not related to ganglia.
• Congenital pyloric stenosis: Affects the pylorus, not related to rectal ganglia.
• Hirschsprung disease: Is a congenital intestinal disorder characterized by the absence of parasympathetic ganglia cells (enteric ganglia) in the rectum and part of the colon.

Answer:

D. Hirschsprung disease
