Overview
Brief Summary
Comparison of confocal laser endomicroscopic in vivo diagnosis and ex vivo examination against surgical histopathology of cystic pancreatic lesions.
Detailed Description
The primary objective of the study is to assess the ability of nCLE (AQ-Flex) to accurately diagnose the type of CPL by comparing in vivo and ex vivo CLE patterns to final histopathology of surgically resected CPLs. The primary endpoints are whether or not the CLE diagnosis correlates with final diagnosis (yes vs. no).

Eligibility Criteria
Inclusion Criteria
- •For in vivo nCLE (needle-based confocal laser endomicroscopy) (Part 1):
