<unk>  is a congenital anomaly of rotation of the midgut (embryologically, the gut undergoes a complex rotation outside the abdomen). As a result:
the small bowel is found predominantly on the right side of the abdomen
the cecum is displaced (from its usual position in the right lower quadrant) into the epigastrium - right hypochondrium
the ligament of Treitz is displaced inferiorly and rightward
fibrous bands (of Ladd) course over the horizontal part of the duodenum (DII), causing intestinal obstruction.
the small intestine has an unusually narrow base, and therefore the midgut is prone to volvulus (a twisting that can obstruct the mesenteric blood vessels and cause intestinal ischemia).
