The Usefulness of Endoscopic Ultrasound-guided Biliary Drainage With a Newly Designed Hybrid Metallic Stent

Pilot Study on the Usefulness of Endoscopic Ultrasound-guided Biliary Drainage With a Newly Designed Hybrid Metallic Stent

The purpose of this study is to investigate the feasibility and safety of endoscopic ultrasound-guided biliary drainage with a newly designed hybrid metallic stent.

Endoscopic ultrasound-guided biliary drainage with a fully covered metallic stent was a safe and effective method in patients with malignant biliary obstructions and had a comparatively long patency duration. Nevertheless, the significant rate of distal stent migration cannot be ignored, suggesting the need for a newly designed metallic stent for endoscopic ultrasound-guided biliary drainage.

Inclusion Criteria:

• Age > 20 years
• The presence of an unresectable malignant biliary obstruction
• Failed conventional ERCP stenting

Exclusion Criteria:

• Age < 20 years
• An inability to sedate the patient due to advanced heart or pulmonary diseases
• A lack of informed consent
