Accuracy of Spybite Forceps When Compared to Conventional Sampling Methods

Prospective Evaluation of the Accuracy of Spybite Biopsy Forceps for the Tissue Diagnosis of Lesion of the Pancreatobiliary System. ( Part of the "The Clinical Utility of Cholangioscopy and Pancreatoscopy in the Diagnosis and Treatment of Pancreaticobiliary Disorders" Study)

The investigators are evaluating the use of a SpyBite biopsy forceps for tissue diagnosis when compared to standard biopsy techniques.

The participants will undergo an Endoscopic Retrograde Cholangiopancreatography (ERCP) with cholangiopancreatoscopy and evaluation of a bile duct or pancreatic duct stricture with three different types of techniques for biopsy: SpyBite biopsy forceps, cytology brush and RJ3biopsy forceps.

3. Lesion of the pancreatobiliary system that requires tissue sampling as medically indicated
4. Subject myst be able to give informed consent
