[Hilar bile duct tumors: Endoscopic or percutaneous drainage? A prospective analysis].

Background And Objective: Both the endoscopic and the percutaneous approach are widely accepted for the drainage of hilar tumors. Our primary objective was to report on the effectiveness and complications of these procedures.

Methods: Prospective observational analysis of the endoscopic and/or percutaneous management of all hilar tumors treated at a referral hospital from October 2011 until October 2014.

[Sphincterotomy plus large balloon dilation versus sphincterotomy alone for the extraction of complex lithiasis: A prospective analysis].

Background And Purpose: Mid-size sphincterotomy associated with large balloon dilation is an alternative to wide sphincterotomy to remove complex lithiases. However, which of the two techniques is most effective remains unclear. Hence, we conducted this study to compare both methods prospectively.
