Malrotation with volvulus of the transverse colon and duodenal obstruction secondary to Ladd's bands.

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 of colonic volvulus (Kerry RL, Ransom HK. Volvulus of the colon: etiology, diagnosis, and treatment. Arch Surg 1969;99:215-221). We report an unusual case of documented volvulus of the transverse colon in a young man with intestinal malrotation and concomitant duodenal obstruction by Ladd's bands.
