Comparing endoscopic scissors cutting nasobiliary ducts to bilateral plastic stents for treating bile duct issues

The Efficacy and Safety of Endoscopic Scissors Cutting Nasobiliary Ducts in the Treatment of Malignant Hilar Biliary Tract Stenosis

Not applicable Interventional First People's Hospital of Hangzhou · NCT06106750

This study is testing if using endoscopic scissors to cut nasobiliary ducts can help patients with bile duct problems feel better compared to the usual plastic stents.

What this trial studies

This study investigates the effectiveness and safety of using endoscopic scissors to cut nasobiliary ducts in patients with malignant hilar biliary tract stenosis. The research aims to improve palliative treatment options for patients who have lost the chance for surgical resection due to late diagnosis. By utilizing nasobiliary ducts, the study seeks to enhance drainage and potentially improve patient outcomes compared to traditional bilateral plastic stents. Participants will undergo endoscopic retrograde cholangiopancreatography (ERCP) as part of the intervention.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 with clinically confirmed malignant hilar biliary duct stenosis who are scheduled for ERCP.

Not a fit: Patients with multiple organ dysfunction, prior biliary drainage, current cholangitis, or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance the quality of life and survival time for patients with malignant hilar biliary tract stenosis.

How similar studies have performed: While this approach is innovative, it builds on existing techniques in endoscopic drainage, and similar studies have shown promise in improving patient outcomes.
