Core Tip
Core tip: Drug-eluting stent is a new therapeutic concept for malignant biliary obstructions; however, studies on such stents have been limited, and all of them used single-drug-loaded nanofilms with a simple design and lacked complete serial in vitro and in vivo data. Our study was the first to apply dual chemotherapeutic medications to a drug-eluting stent with several improvements in the design compared to previous stents for the palliative therapy of extrahepatic cholangiocarcinoma, with a relatively complete preclinical evaluation. Our results indicate that this brand new stent can be a promising alternative to realize the dual functions of biliary drainage and local chemotherapy.
