Endoscopic Management of Malignant Biliary Obstruction
Endoscopic retrograde cholangiopancreatography (ERCP) is commonly used for managing malignant biliary obstruction; however, it is impossible if the endoscope cannot reach the ampulla of Vater, and it carries a risk of procedure-related pancreatitis. Percutaneous approach is a traditional rescue method when ERCP fails and can be useful in advanced malignant hilar biliary obstruction; however, it is invasive and carries risks of tube dislodgement, recurrent infection, and tract seeding. Endoscopic ultrasound approach may be attempted if ERCP fails and is free from the risk of pancreatitis; however, it is only possible in limited centers, and training is still difficult. Malignant biliary obstruction should be managed by leveraging the complementary strengths of these methods.
