Malrotation with transverse colon volvulus in early pregnancy: a rare cause for acute intestinal obstruction.

Colonic volvulus is a relatively uncommon cause of large bowel obstruction, accounting for 10% of colonic obstructions. Volvulus of the transverse colon is quite rare, accounting for only 4-11% of all reported cases. We report an unusual case of documented volvulus of the transverse colon in a pregnant woman with intestinal malrotation and concomitant acute intestinal obstruction by congenital bands and adhesions.
