Treatment for intrahepatic bile duct (IHBD) stones remains a challenge. Although endoscopic ultrasound (EUS)-guided antegrade treatment for biliary stones has been reported recently [1] [2], this method is indicated for stones in the common bile duct or left IHBD. For right IHBD stones, percutaneous transhepatic biliary drainage-guided treatment is usually performed. Herein, we describe an endoscopic treatment procedure for right IHBD stones through an EUS-guided hepaticogastrostomy (HGS) route.
A 74-year-old man who had undergone pancreaticoduodenectomy for pancreatic cancer was admitted to our hospital because of IHBD stones detected by computed tomography. The stones were located both in the left and right IHBD ([Fig. 1]). Single-balloon enteroscope-assisted endoscopic retrograde cholangiography showed the stones were trapped in segments 3 (B3) and 6 (B6) of the IHBD ([Fig. 2]), and that the right posterior segmental duct drained into the left hepatic duct. Because neither a balloon catheter nor a basket catheter could be passed due to the biliary tree bending and the impacted stones, the treatment failed. We then performed EUS-HGS for B3 by using a plastic stent (Type IT; Gadelius Medical Co., Ltd., Tokyo, Japan) in order to create a treatment route ([Fig. 3])

The patient was readmitted 1 month later for stone removal via the HGS route. First, we attempted to treat the B6 stone. We placed the guidewire in B6 by using a catheter with bendable tip (Swing Tip; Olympus Medical Systems, Tokyo, Japan). We were then able to insert a mechanical lithotripter (LithoCrush V; Olympus Medical Systems), and succeeded in crushing the B6 stones ([Fig. 4], [Video 1]). Finally, we placed the plastic stent (Type IT) again for the next treatment.

This case suggests that endoscopic treatment through an EUS-HGS route can be useful even for right IHBD stones.
