Question:

What is the normal congenital rotation that the small bowel undergoes in normal development?
1. 360o clockwise rotation around the superior mesenteric artery
2. 270o counter clockwise rotation around the inferior mesenteric artery
3. 270o clockwise rotation around the inferior mesenteric artery
4. 360o counter clockwise rotation around the superior mesenteric artery
5. 270o counter clockwise rotation around the superior mesenteric artery





Answer:

The correct answer for the question "What is the normal congenital rotation that the small bowel undergoes in normal development?" is:

5. 270o counter clockwise rotation around the superior mesenteric artery



Explanation
As in the introduction "it is a congenital failure of the small bowel to complete the full 270o counter clockwise rotation around the superior mesenteric artery".

Abstract
Malrotation with associated volvulus is a potentially lethal event for a neonate. The gold standard for diagnosis is an upper gastrointestinal contrast study. However this can delay the diagnosis and the timing of surgical intervention. We present a novel abdominal radiographic sign; duodenal and gastric dilatation occurring in association with limited small bowel gas confined to the right lower quadrant of abdomen and the total absence of colonic air that is indicative of malrotation with associated volvulus. This allows for an earlier diagnosis and expeditious surgery.
