Endoscopic Retrograde CholangioPancreatography Endomicroscopy Registry Outcomes Database

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

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
