Epidemiology of intrahepatic, perihilar, and distal cholangiocarcinoma in the French population.

Objectives: The objective of this study was to investigate the differences between cholangiocarcinoma (CC) subtypes in terms of incidence rate, clinical presentation, management and survival by applying a stable anatomical classification in a population-based study.

Patients And Methods: Cancer data for the period 2000-2012 were obtained from a specialized digestive cancer registry in the Department of Calvados, France. Patients' files were checked, and the diagnosis was verified by two hepatobiliary surgeons.

Preoperative Biliary Drainage in Patients with Resectable Perihilar Cholangiocarcinoma: Is Percutaneous Transhepatic Biliary Drainage Safer and More Effective than Endoscopic Biliary Drainage? A Meta-Analysis.

Purpose: To determine the best initial procedure for performing preoperative biliary drainage in patients with resectable perihilar cholangiocarcinoma (PHCC).

Materials And Methods: MEDLINE/PubMed and the Cochrane database were searched for all studies published until June 2016 comparing endoscopic biliary drainage (EBD) and percutaneous transhepatic biliary drainage (PTBD) for preoperative biliary drainage. Meta-analysis was performed by using Review Manager 5.
