Endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD) is not normally indicated for an obstructed right intrahepatic bile duct (IHBD). The technical feasibility and clinical efficacy of a novel technique of EUS-BD for right IHBD obstruction were evaluated. A total of 11 patients underwent drainage using either a left or a right biliary access route. The causes of obstructive jaundice were cholangiocarcinoma (n = 6), pancreatic cancer (n = 3), gastric cancer (n = 1), and colon cancer (n = 1). After placement of an uncovered metal stent to bridge the obstruction, a hepaticogastrostomy was completed using a covered stent. Mean procedure time was 33.9 ± 10.0 minutes. Technical and functional success were achieved in all patients, and no adverse events occurred. This novel method appears to be safe and effective for right IHBD obstruction.
