Evaluating combined EUS and ERCP for treating bile duct obstructions

Endoscopic Retrograde Cholangiopancreatography With and Without Endoscopic Ultrasound Guided Hepaticogastrostomy for Bilateral Biliary Decompression in Malignant Hilar Biliary Obstruction

Not applicable Interventional Mansoura University · NCT06613945

This study is testing whether a new method that combines two procedures can help people with advanced bile duct blockages feel better compared to just one of the procedures alone.

What this trial studies

This clinical trial aims to assess the efficacy and safety of combining Endoscopic Ultrasound Guided Hepaticogastrostomy (EUS-HGS) with Endoscopic Retrograde Cholangiopancreatography (ERCP) for bilateral biliary decompression in patients with advanced malignant hilar biliary obstruction. Participants will be randomly assigned to receive either ERCP alone or the combined approach, with outcomes measured including technical success, clinical success, procedural duration, and rates of adverse events. Follow-up assessments will occur at one and three months post-procedure to evaluate the effectiveness of the interventions.

Who should consider this trial

Good fit: Ideal candidates are patients with inoperable malignant hilar biliary obstruction and elevated liver tests.

Not a fit: Patients with benign biliary stenosis or those with previous failed biliary interventions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve biliary drainage and reduce complications for patients with malignant hilar biliary obstruction.

How similar studies have performed: While the combination of EUS-HGS and ERCP is a novel approach, similar studies have shown promising results in improving biliary drainage outcomes.
