Operative endoscopy in the management of biliary tract neoplasms.
Operative endoscopy of the biliary system has been employed with ever increasing frequency at the UCLA Hospital during the last three years. In addition to its established value with respect to disclosing unsuspected stones in the bile ducts, choledochoscopy has been of great value in terms of more accurate diagnosis and staging of periampullary and bile duct neoplasms. It has been observed that many biliary tract carcinomas are multicentric in origin and that cholangiography is not adequate to identify small intrahepatic ductal lesions. More than one cell type of bile duct carcinoma may be present in the same patient. Choledochoscopy should be used in addition to the conventional criteria for resectability in all patients with ductal or periampullary carcinoma. Use of this technic will spare some patients needless radical procedures and should improve long-term cure rates by identifying those patients with truly localized disease for curative resections.
