EUS-guided procedure for treating benign biliary obstructions

EUS-guided Entero-biliary Anastomosis as Fistulas for Therapeutic Access in Benign Biliary Obstructions Not Accessible by ERCP

Hospital del Rio Hortega · NCT05246657

This study is testing a new way to treat benign bile duct blockages using a special stent for patients who haven't had success with other treatments.

What this trial studies

This observational study aims to evaluate the feasibility and effectiveness of EUS-guided entero-biliary anastomosis using covered self-expandable metal stents for patients with benign biliary obstructions. The study will involve a prospective multicenter case series at the Río Hortega University Hospital, where patients who have failed endoscopic retrograde cholangiopancreatography (ERCP) or have surgically-altered anatomy will be assessed. Participants will undergo a clinical evaluation and endoscopic procedure under sedation, with the goal of providing biliary drainage and facilitating further endotherapy. The study will focus on patients who meet specific inclusion criteria and do not have any exclusion factors.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with benign biliary obstruction who have experienced failure of ERCP or have surgically-altered anatomy.

Not a fit: Patients with malignant biliary obstructions, coagulopathy, or those unable to tolerate sedation will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a new therapeutic option for patients with benign biliary obstructions who are not candidates for traditional ERCP.

How similar studies have performed: While the approach is gaining acceptance, the specific use of transmural EUS-guided entero-biliary anastomosis in this context is still being evaluated and may be considered novel.
