Abstract
- A prerequisite for endoscopic ultrasound (EUS)‐guided hepaticogastrostomy (HGS) is adequate dilation of the intrahepatic bile duct. Compared with a 19G needle, the 22G needle offers more flexible manipulation and superior ability to achieve bile duct puncture. However, evidence regarding EUS‐HGS using a 22G needle remains limited. The present study evaluated the feasibility and safety of EUS‐HGS using a novel 0.018‐inch guidewire and 22G needle for patients with insufficient intrahepatic bile duct dilation. If the bile duct diameter was <1.5 mm, a 22G needle was used, and the diameter was ≥1.5 mm; puncture with a 19G needle was first attempted, with the 22G needle being inserted if initial bile duct puncture failed. EUS‐HGS using the 22G needle was attempted in a total of 10 patients, including one patient with failed insertion of a 19G needle. Median diameter of the puncture site was 1.2 mm (range 0.5–2.5 mm). Bile duct puncture using the 22G needle was successful in all patients. Insertion of the novel 0.018‐inch guidewire was also successful in all patients. However, since tract dilation using an ultra‐tapered mechanical dilator failed in two patients, tract dilation was performed using a balloon dilator. Finally, stent deployment was successfully performed in all patients. EUS‐HGS using a 22G needle with a novel 0.018‐inch guidewire appears safe and feasible. [ABSTRACT FROM AUTHOR]
