A Biliary Cytology Brush is a slender, flexible endoscopic tool used to collect cell samples from the bile ducts during procedures like ERCP (Endoscopic Retrograde Cholangiopancreatography) for diagnostic purposes, especially to detect cancer or strictures.
Key Features:
Nylon bristles: Designed to gently collect epithelial cells
Radiopaque tip or markers: For accurate positioning under fluoroscopy
Flexible catheter shaft: Navigates easily through the biliary tree
Sterile and single-use: Ensures patient safety and hygiene
Uses:
Sampling bile duct lesions or strictures for cytological analysis
Diagnosing cholangiocarcinoma (bile duct cancer) or benign vs. malignant strictures
Commonly used in ERCP for evaluating biliary obstruction
