Staging laparoscopy for cholangiocarcinoma

Abstract

The precise role of laparoscopic assessment of biliary tract malignancy is yet to be defined. The evidence for its use has been reviewed to establish the role of laparoscopy for preoperative staging of cholangiocarcinoma. Published papers were reviewed for the evidence relevant to intrahepatic, proximal intrahepatic and distal biliary carcinoma. There is no randomized trial evaluating staging laparoscopy or laparoscopic ultrasound in the assessment of cholangiocarcinoma and the quality of the available data is extremely variable. There is a need for further studies to determine the specific role of laparoscopic staging of cholangiocarcinoma. The current standard of management should be to perform laparoscopic staging prior to proceeding to resection for patients with cholangiocarcinoma as it may prevent unnecessary laparotomy in up to 30% of patients. However, a selective approach identifying high-risk patients who will not benefit from surgical palliation may be more cost effective and future studies should be performed to identify such patients.
