Although considered rare, transverse colon volvulus (TCV) may actually comprise as many as 10% of all cases of colon volvulus. Correct identification clinically is necessary in order to reduce the high mortality. Unlike the treatment of sigmoid volvulus, conservative treatment of TCV is thought to be inadequate. Furthermore, simple proximal colostomy may lead to bowel necrosis. Bowel resection, rather than detorsion procedures, is advocated. The barium or diatrizoate enema examination can readily differentiate TCV from sigmoid and cecal volvulus if one pays careful attention to detail.
