The Comparison of Endoscopic Biliary Drainage in Malignant Hilar Obstruction by Cholangiocarcinoma: Bilateral Metal Stents versus Multiple Plastic Stents.

ABSTRACT:

Background/aims

For the management of hilar malignant biliary obstruction (HMBO), endoscopic biliary drainage (EBD) is preferred over percutaneous transhepatic biliary drainage (PTBD) because of its convenience. However, there is no established guideline for malignant hilar obstruction that requires multiple stenting. In this study, we compared the efficacy of bilateral metal stents (BMS) versus multiple plastic stents (MPS).

Methods

In this retrospective study, we analyzed 102 patients who underwent EBD with either BMS or MPS due to HMBO caused by hilar cholangiocarcinoma between 1996 and 2018 at Samsung Medical Center. We compared the successful drainage rates, cholangitis events, overall complications, mortality, and conversion rates to PTBD between the two groups.
