The novel technique of drainage stenting using a tapered sheath dilator in endoscopic ultrasound-guided biliary drainage.

ABSTRACT: During endoscopic ultrasound-guided biliary drainage (EUS-BD), there is a risk for bile leakage until stent deployment, which can result in severe peritonitis, particularly when passing a drainage stent becomes challenging despite tract dilation. There is no established method or dedicated device to optimize EUS-BD. Therefore, we have developed a novel stent deployment technique using the tapered sheath dilator. To address the safety and technical aspects of the EUS-BD technique, we retrospectively analyzed 11 consecutive patients who underwent EUS-BD using the tapered sheath dilator. The procedure involved the insertion of a guidewire, followed by mechanical dilation using the tapered sheath dilator. Subsequently, the inner catheter was removed and drainage stents (up to 6 Fr in diameter)
