GUIDI, Martín Alejandro et al. Hilar bile duct tumors: Endoscopic or percutaneous drainage?: a prospective analysis. Rev. esp. enferm. dig. [online]. 2015, vol.107, n.8, pp.488-494. ISSN 1130-0108.

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. Group A included patients treated endoscopically and group B included patients treated with percutaneous drainage. The following variables were assessed: Effective biliary drainage rate, survival time and complications. Results: Group A comprised 40 patients and group B, 22 patients. Overall success rate in achieving effective biliary drainage was 85% in group A and 90.9% in group B (p = 0.78). Five patients required a combined approach. In group A, the rate of effective drainage in patients with Bismuth IV-type tumors was 58.3%, while it was 81.8% in patients in group B (p = 0.44). There was no difference in mean survival between both groups. For group A, complication rate was 11.5%, whereas it was 2.94% for group B (p = 0.41). Conclusions: Endoscopic and percutaneous biliary drainage are both effective methods for the palliative treatment of patients with hilar tumors. However, for Bismuth IV-type strictures, percutaneous drainage proved to be safer and more effective.
