EUS-guided procedure for treating bile duct obstructions

EUS-guided Hepatico-gastrostomy Using a Novel Lumen Apposing Metal Stent

Not applicable Interventional Chinese University of Hong Kong · NCT05169398

This study is testing a new type of stent to help people with bile duct blockages who couldn't get relief from a standard procedure, to see if it works better and is safer.

What this trial studies

This study evaluates the feasibility and outcomes of a novel lumen apposing metal stent for EUS-guided hepaticogastrostomy in patients with malignant biliary obstruction who have had unsuccessful endoscopic retrograde cholangiopancreatography (ERCP). The procedure aims to provide an alternative drainage method when ERCP fails due to inaccessible papilla or tumor infiltration. The study will assess the safety and effectiveness of the new stent design, which is intended to prevent migration and improve patient outcomes. Patients will be recruited based on specific inclusion criteria and monitored for technical and clinical success.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years old with clinical symptoms of biliary obstruction and a history of unsuccessful ERCP.

Not a fit: Patients who are pregnant, breastfeeding, or have coagulopathy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a safer and more effective treatment option for patients with malignant biliary obstruction.

How similar studies have performed: While EUS-guided biliary drainage is gaining popularity, this specific approach with the novel stent design is relatively novel and has not been extensively tested in prior studies.
