Endoscopic ultrasonography-guided biliary drainage included the rendezvous technique, direct transmural ostomy formation (hepatogastrostomy, hepatoduodenostomy, hepatojejunostomy), and antegrade stenting. HGS: Hepatogastrostomy; EUS: Endoscopic ultrasonography; ERCP: Endoscopic retrograde cholangiopancreatography; EUS-BD: Endoscopic ultrasonography-guided biliary drainage; LAMS: Lumen-apposing metal stent.
