ABSTRACT
Tract dilation is one of the most difficult stages of endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), especially for beginners. To overcome this problem, we applied a special dedicated dilator. Herein, we retrospectively evaluate the safety and usefulness of a novel drill dilator in EUS-HGS. This single-center retrospective study included 20 consecutive patients who underwent EUS-HGS with a novel drill dilator. The tip is 0.77 mm, and it becomes 7F at 3 cm from tip. The track is dilated to 7F by simple clockwise rotation. The technical success rate of both initial tract dilation and stent placement was 20/20 (100%). No cases required additional dilation such as balloon or electric cautery. In 13/20 cases (65.0%), EUS-HGS was performed by beginner endoscopists. Median time required for dilation was 62.5 s (range, 30-144 s). Median procedure time was 13 min (range, 7-25 min). Early adverse events were two cases of mild fever. There was no bile leakage or bleeding. The novel drill dilator appears to be safe and useful for EUS-HGS. As it is not necessary to press the device strongly, there is no pushback during dilation and the scope position is stable. These characteristics facilitate EUS-HGS even for beginners. This device may enable the further development and increased dissemination of EUS intervention.
