EUS-guided drainage of the gallbladder (EUS-GBD) is an established technique for gallbladder drainage.,, Although the usefulness of a lumen-apposing metal stent has been widely reported,, it is not available in every institution; hence, techniques on how to safely perform EUS-GBD should be available.
Gallbladder puncture using a thin 22-gauge needle for EUS-FNA (22G FNA needle) is a good method to reduce complications such as bile leakage. However, this has not been feasible due to the lack of an appropriate 0.018-inch guidewire compatible with EUS-guided drainage with good X-ray fluoroscopy visibility and maneuverability.
A 68-year-old woman with obstructive jaundice due to pancreatic head cancer was referred to our hospital. Transpapillary biliary drainage with a covered metallic stent (MS) (X-Suit NIR; Olympus, Tokyo) was performed. After the procedure, jaundice improved, but acute cholecystitis occurred.
Percutaneous drainage was contraindicated due to ascites; hence, EUS-GBD was performed. A 22G FNA needle puncture was performed to minimize bile leakage. We used a new 0.018-inch guidewire (18 Fielder; Olympus, Tokyo) with a hydrophilic coating coil tip and a hard core, enabling both the ease of manipulation and the appropriate hardness required for device insertion [Figure 1].

The guidewire was manipulated to the proper location in the gallbladder lumen with good fluoroscopy visibility. After expanding the puncture site to 3 mm with a balloon catheter, the inner sheath of the MS (Niti-S; Taewoong, South Korea) was inserted into the gallbladder with good pushability even though the guide wire was 0.018 inch. Finally, EUS-GBD was successful without any complications [Figure 2] and [Video 1 [Additional file 1]].

This is the first case of EUS-GBD performed with a 22G needle and a novel 0.018-inch guidewire. It is expected that advances in devices like this will continue to be utilized to make EUS-guided drainage safer.
