EUS-guided biliary drainage (EUS-BD) has been developed for failed or difficult ERCP. In particular, EUS-guided antegrade stenting (EUS-AGS) combined with EUS-guided hepaticogastrostomy (EUS-HGS) is suitable for gastric outlet obstruction (GOO) or surgically altered anatomy. However, EUS-BD requires fistula dilation before stenting and carries the potential risk of bile leak from the fistula. Herein, we present the case of a patient who underwent EUS-HGS combined with EUS-AGS for unresectable duodenal cancer, using novel ultra-slim devices.
A 78-year-old woman presented with a 1-week history of vomiting and obstructive jaundice. Esophagogastroduodenoscopy revealed advanced duodenal cancer and GOO [Figure 1]a. Contrast-enhanced computed tomography showed distal bile duct obstruction caused by the duodenal cancer [Figure 1]b. We performed EUS-AGS combined with EUS-HGS for BD. First, a B3 branch was punctured using a 19G needle, and a 0.025“ stiff guidewire (VisiGlide 2, Olympus Inc. Tokyo, Japan) was placed [Video 1]. Next, a tapered ERCP catheter was used to dilate the fistula following successful passage of the guidewire through the distal bile duct stricture. Then, EUS-AGS was performed using a novel ultra-slim uncovered self-expandable metal stent (ZEOSTENT V; 5.4-Fr delivery system, 10-mm diameter; Zeon Medical Inc. Tokyo, Japan) [Figure 2]a and[Figure 2]b. Finally, a novel 7-Fr plastic stent (TYPE-IT stent; Gadelius Medical Co. Ltd., Tokyo, Japan) [Video 1] was placed to create an EUS-HGS without any complications [[Figure 2]c and Video 1].

Bile leaks are a concern during EUS-BD, and they can be minimized by avoiding unnecessary dilation and reducing device exchanges. Ultra-slim devices (7-Fr or less) are suitable as they can facilitate the procedure., Ultra-slim devices also allow for relatively easy stent deployment with less frequent microdamage to the echoendoscope. Although a consensus cannot be reached in EUS-BD, EUS-AGS combined with EUS-HGS using ultra-slim devices is safe. Thus, the development of uncovered metallic stents with ultra-slim delivery is a key for successful procedure.
