Management of duodenal involvement in locally advanced colonic carcinoma.

Removal of locally advanced right-sided colonic carcinoma involving the duodenum can be challenging. There are few data on the optimal surgical approach. Adjacent organ involvement is associated with a poor prognosis and may be classified as inoperable with patients having palliative bypass procedures rather than primary resection. Survival is however improved after en bloc resection of adjoining viscera compared with intestinal bypass. We present a variety of surgical options depending on the extent of local invasion and the debility of the patient.
