A 72-year-old female with advanced rectal cancer presented with obstructive jaundice 6 months after undergoing left hepatic lobectomy for liver metastases. Computed tomography revealed a dilated right intrahepatic bile duct, and a new liver metastasis appeared in her right hepatic lobe [Figure 1]a. Endoscopic retrograde cholangiopancreatography (ERCP) revealed severe stricture at the hepatic hilum; however, insertion of an ERCP catheter into the right anterior intrahepatic duct was unsuccessful [Figure 1]b. Subsequently, endoscopic ultrasonography-guided right hepatic bile duct drainage (EUS-RBD) was attempted. The right anterior intrahepatic duct could be well-visualized with an echoendoscope from the duodenal bulb and was punctured with a 19-gauge aspiration needle [Figure 2]a. A 0.025-inch angle-tip guidewire (VisiGlide 2; Olympus Medical Systems, Tokyo, Japan) was inserted into the biliary system [Figure 2]b, and following dilation of the fistula track by a 7-Fr biliary bougie dilator (Soehendra Biliary Dilation Catheter, Cook Medical, Winston-Salem, North Carolina, USA), a covered self-expandable metal stent (10 mm × 100 mm, Niti-S Biliary Covered Stent; Taewoong Medical, Seoul, South Korea) was successfully deployed through the duodenal bulb [Figure 2]c and [Video 1]. The total procedure time was 42 min. The postoperative period was uneventful, and both jaundice and never mentioned before resolved in a week. Chemotherapy was resumed for advanced rectal cancer immediately after discharge. The patient died 767 days after EUS-RBD because of the progression of her underlying disease; however, she remained free of jaundice until death.

EUS-guided biliary drainage is a recently developed alternative technique in patients with biliary obstruction for failed ERCP., Various techniques have been described; however, limited data are available regarding EUS-RBD ,, and long-term follow-up data are lacking. This is the first case which attained long-term stent patency in EUS-RBD after left hepatic lobectomy.
The use of the Spyglass System (Boston Scientific, Natick, Massachusetts, USA) to facilitate selective placement of a guidewire in the context of difficult biliary strictures has been reported. However, even if a guidewire had been successfully inserted across this stricture, the configuration and site of the stricture would have made placement of a self-expandable metal stent difficult, and a plastic stent would have to be used. Plastic stents tend to occlude within a few months, and the patient would have had to undergo repeat ERCP procedures for palliative drainage. In contrast, EUS-RBD using a self-expandable metal stent allowed long lasting effective drainage.
In conclusion, EUS-RBD could be an effective palliative option for right intrahepatic bile duct drainage, which is expected to maintain the patient's quality of life and achieve long-term stent patency and survival.
