Using a new cholangioscopy system to screen for bile duct cancer

Efficacy of Single-operator Cholangioscopy to Screen for Neoplastic Bile Duct Lesions in Patients With Bile Duct Stones

Observational Soonchunhyang University Hospital · NCT05600803

This study is testing a new tool called the SpyGlass DS II to see if it can help find early signs of bile duct cancer in patients who are at risk.

What this trial studies

This observational study aims to evaluate the effectiveness of the SpyGlass DS II system for screening early-stage neoplastic bile duct lesions in patients with risk factors for cholangiocarcinoma. Traditional imaging methods like CT and MRI often fail to provide tissue diagnoses, while ERCP has limited diagnostic accuracy. The SpyGlass system allows for single-operator cholangioscopy, which may improve the detection of these lesions during ERCP procedures. The study will focus on patients with dilated common bile ducts who are undergoing ERCP for confirmation of CBD clearance.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with specific risk factors for cholangiocarcinoma who are undergoing ERCP.

Not a fit: Patients with existing biliary tract cancer or those with contraindications for ERCP may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to earlier and more accurate diagnoses of bile duct cancers, improving patient outcomes.

How similar studies have performed: While cholangioscopy has been explored in other studies, the specific use of the SpyGlass DS II system for this purpose is relatively novel.
