"Post-operatively the duodenum and small bowel remain on the right, and the caecum and colon are on the left side of the abdomen 5,6."
"In incomplete rotation, the midgut does not rotate more than 180°, thus the cephalad (prearterial proximal) portion of the midgut is fixed to the right of the superior mesenteric artery (SMA) while the caudad (postarterial distal) midgut is fixed directly anterior to the SMA."
"intra- and extra-hepatic biliary atresia"
"A more useful sign to rule out intestinal malrotation is the demonstration the retro-mesenteric D3 segment of the duodenum, where the horizontal (D3) segment of the duodenum should be seen in a transverse plane between the superior mesenteric vessels and the aorta 8,10,12."
"Although demonstrating a retro-mesenteric duodenum is extremely sensitive and specific for excluding malrotation, it is not perfect and such a normal anatomic relationship has been described in at least one case of surgically treated intestinal malrotation with midgut volvulus 9. This case was likely secondary to partial intestinal malrotation, based on the embryological delay described above between the rotation of the duodenojejunal loop and the caecocolic loop."
