Endoscopic Retrograde Cholangiopancreatography (ERCP) has long been used in the evaluation and treatment of biliary strictures and masses. In addition to imaging the biliary tree and pancreatic duct, ERCP allows for tissue acquisition. Both cytology and forceps biopsies can be used. Studies have shown the sensitivity of standard brush cytology to be 35-70% [1-3] and forceps biopsy to be 40-80% [4,5]. Wide-Area Transepithelial Sampling 3Dimensional Analysis (WATS3D(R) Brush Biopsy, CDx, Suffrin, NY) computer assisted full thickness brush biopsy is a method of tissue collection that samples the total thickness of the epithelium.
