Selection of preoperative biliary drainage of perihilar cholangiocarcinoma / 国际外科学杂志

ABSTRACT

Preoperative biliary drainage (PBD) has become an essential part of perioperative management for perihilar cholangiocarcinoma. However, it is controversial about the indication of PBD. There are three main PBD methods, including percutaneous transhepatic biliary drainage, endoscopic nasobiliary drainage and endoscopic biliary stenting. At present, different centers have different preferences on PBD, and the controversies mainly focus on the followings the relationship between percutaneous transhepatic biliary drainage and seeding metastasis; the success rate, tolerance and pancreatitis risk of endoscopic nasobiliary drainage; as an internal drainage, the merits and demerits of endoscopic biliary stenting. Additionally, whether PBD could increase the incidence of postoperative infections is still ambiguous. This review summarizes the recent scenario about the above-mentioned controversies to provide references for clinical decision-making.
