Malrotation of small bowel

What it means

A deviation from the normal rotation of the midgut during embryologic development with mislocalization of the small bowel.

Malrotation results not only in the malposition of the bowel but also in the malfixation of the mesentery. The normally broad mesenteric attachment is shortened to a narrow pedicle that predisposes the patient to the complication of midgut volvulus.
