This registry will collect data from patients routinely undergoing an ERCP and Cellvizio endomicroscopy procedure (and optionally an additional cholangiopancreatoscopy procedure) due to suspected pancreatic or bile duct cancer. The objective is to determine if endomicroscopy images collected using the marketed Cellvizio device may help endoscopists more accurately diagnose, in conjunction with traditional tissue sampling techniques, whether a suspected lesion is malignant or benign.

This is a registry study to collect high quality longitudinal data from patients with suspected or indeterminate pancreaticobiliary pathology who are undergoing an ERCP with Cellvizio probe-based endomicroscopy procedure, with or without supplemental direct cholangiopancreatoscopy. The hypothesis is that ERCP with Cellvizio probe-based endomicroscopy improves differentiation of biliary and pancreatic duct lesions versus ERCP alone.

Direct measures of accuracy (sensitivity, specificity, etc.) in the differentiation of malignant versus benign biliary and/or pancreatic duct lesions will be compared for the combination of endomicroscopy and ERCP imaging and ERCP alone. These presumptive diagnoses will be compared against a 12-month follow-up confirmed histopathologic endpoint (an initially-benign pathologic diagnosis will be confirmed by a 12-month follow-up). Secondary objectives include collecting various safety and technical performance parameters.

Inclusion Criteria:

1. Male or female > 18 years of age
2. Willing and able to comply with Registry procedures and provide written informed consent to participate in the Registry
3. Indicated for ERCP and/or cholangiopancreatoscopy
4. Indeterminate or suspected biliary and/or pancreatic stricture, mass, or neoplasm

Exclusion Criteria:

1. Subjects for whom ERCP procedures are contraindicated
2. Known allergy to fluorescein dye
