Endoscopic ultrasound-guided hepaticoduodenostomy with anterograde stenting for recurrent hepatic hilar obstruction

We present the case of a 52-year-old woman who underwent endoscopic ultrasound-guided hepaticoduodenostomy (EUS-HDS) with anterograde stenting. She had undergone side-by-side stent drainage (the left hepatic and anterior bile ducts) for Bismuth type II hilar bile duct obstruction (HBO) caused by intrahepatic cholangiocarcinoma. She was diagnosed with cholangitis in the posterior bile duct (B6) due to stent occlusion 2 months later. Endoscopic retrograde cholangiopancreatography was performed, but the catheter could not be inserted into B6 ([Fig. 1]). Although balloon dilation of the stent mesh was performed, even the thinnest (5.7 Fr) uncovered self-expandable metal stent (UCSEMS) could not be inserted. Therefore, we performed anterograde stenting via EUS-HDS.

The EUS scope was inserted into the descending duodenum. The B6 duct was identified and punctured with a 19G needle. A 0.025-inch guidewire was inserted from B6 into the common bile duct (CBD) through the mesh of the previous UCSEMS. The fistula site was dilated with a 4-mm balloon. A UCSEMS (8 mm × 6 cm; ZEOSTENT; Zeon Medical, Tokyo, Japan) was deployed from B6 to the CBD using anterograde stenting. Additionally, a fully covered SEMS (8 mm × 8 cm; X-SUIT NIR; Olympus, Tokyo, Japan) was deployed at the fistula site. Finally, cholangiography was performed and confirmed the passage of contrast from B6 via the CBD to the duodenum ([Fig. 2]; [Video 1]).

Post-procedure computed tomography revealed that the intrahepatic bile duct dilatation had disappeared ([Fig. 3]). There were no procedure-related complications. Clinically, with the cholangitis improved, the patient was able to resume her chemotherapy.

Reintervention after SEMS deployment for HBO is difficult because it is performed after multi-stenting with a UCSEMS. EUS-HDS [1] [2] [3] is an alternative drainage route for HBO; however, there were no reports on EUS-HDS with anterograde stenting. This is the first report demonstrating the usefulness of EUS-HDS with anterograde stenting as a rescue drainage procedure for HBO cases wherein reintervention is difficult.
