Intestinal malrotation

Summary of Intestinal malrotation
Intestinal malrotation is a congenital anomaly of rotation of the midgut. As a result: the small bowel is found predominantly on the right side of the abdomen; the cecum is displaced into the epigastrium. The small intestine has an unusually narrow base, and therefore the midgut is prone to volvulus. Patients (often infants) present acutely with midgut volvulus, manifested by bilious vomiting, crampy abdominal pain, abdominal distention, and the passage of blood and mucus in their stools.
