title: A new method to obtain a tissue diagnosis of proximal bile duct tumors.
abstract: Klatskin tumors often pose a challenge for diagnosis and treatment. Most of these neoplasms are diagnosed clinically because of the difficulty in obtaining tissue that will provide histologic proof of the disease. When a non-operative course is sought, exhaustive attempts should be made to obtain a tissue diagnosis because of the potential for a false-positive clinical diagnosis. We describe a new way to obtain tissue for diagnosis by placing a laparoscopic choledochoscope through a percutaneous transhepatic cholangiogram track, thus allowing the tumor to be directly visualized and biopsied.
