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.
