Endoscopic ultrasound-guided biliary drainage: Complications and their management

Isayama H, Nakai Y, Yamamoto N, Matsubara , Ito Y, Kogure H, Hamada T, Koike K

Endoscopic ultrasound-guided biliary drainage (EUS-BD), EUS-guided choledochoduodenostomy (EUS-CDS), and EUS-guided hepaticogastrostomy (EUS-HGS) can effectively palliate obstructive jaundice, but have not been well established yet. The incidence of complications is about...
