Question 12#

Failure of fixation of the small intestinal and right colonic mesentery during gestation can result in:

A. Chronic constipation
B. Intestinal malrotation
C. Umbilical hernia
D. Intussusception

Correct Answer is B


During fetal development, after the midgut rotates and returns to the abdominal cavity, the mesentery of the duodenum, small intestine, and proximal colon become fixed to the retroperitoneum. Failure of fixation results in a spectrum of disorders associated with intestinal malrotation.
