Biliary neoplasms.

Abstract

Several large series have been reported describing extensive surgery for gallbladder cancer; prolonged survival, however, has not been shown compared with more conservative treatment. Although in the case of bile duct tumors, excision of adjoining structures might confer some benefit and further improvement might be seen by the use of radiotherapy. Accurate preoperative imaging is beginning to be beneficial in the selection of patients for the different modalities of treatment.
