Comparison of confocal laser endomicroscopic in vivo diagnosis and ex vivo examination against surgical histopathology of cystic pancreatic lesions.
Condition or disease
Cystic Pancreatic Disorders
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).

Sexes Eligible for Study:
Accepts Healthy Volunteers:
Patients with Cystic Pancreatic Lesions
For in vivo nCLE (needle-based confocal laser endomicroscopy) (Part 1):
Patient age 18 years and older
All patients referred for EUS-FNA (endoscopic ultrasound - fine needle aspiration) of accessible CPL (cystic pancreatic lesion)
The minimum size of the cyst should be ≥ 1.5 cm as determined by prior cross-sectional imaging studies.

All patients must satisfy inclusive criteria for in vivo nCLE.
All patients should have completed EUS-guided nCLE.
All patients should have a CPL lesion referred for surgical removal based on recommended international consensus guidelines1 and inter-departmental consensus pancreatic tumor board meeting (departments of surgical oncology, radiology, pathology and gastroenterology).
