Abstract Endoscopic ultrasound (EUS)‐guided transhepatic biliary drainage is usually performed with a 19‐gauge fine‐needle aspiration (FNA) needle and a 0.025‐inch guidewire. The combination of a 22‐gauge FNA needle and a 0.018‐inch guidewire is reported to be effective as a rescue option when the bile duct diameter is small or technically challenging. Experts in EUS‐guided transhepatic biliary drainage have reported that bile duct puncture with a 19‐gauge FNA needle is possible in most cases, but is not easy to reproduce by endoscopists with less experience in EUS‐guided transhepatic biliary drainage. We investigated the usefulness of EUS‐guided transhepatic biliary drainage using a 22‐gauge FNA needle and a 0.018‐inch guidewire during the procedure's induction phase. Consecutive patients who underwent EUS‐guided transhepatic biliary drainage at our institution from March 2021 to May 2023 were evaluated, and 37 were included. Biliary drainage was performed for malignant bile duct stricture in 36 patients and choledocholithiasis in one patient. The median target bile duct diameter was 4.5 mm (2.5–9.4). Biliary access, fistula dilation, and stent placement were successful in the 37 patients (100%). The median procedure time was 35 min (16–125). Adverse events occurred in four (10.8%) patients. EUS‐guided transhepatic biliary drainage using a 22‐gauge FNA needle and a 0.018‐inch guidewire is a useful and promising option for endoscopists with limited experience in EUS‐guided transhepatic biliary drainage in the procedure's induction phase.
