  Purpose

This study focuses on four different lesions: pancreatic cysts, lymph nodes near the gastrointestinal tract, pancreatic masses and GIST tumors.

On one hand, the results obtained during previous studies are more advanced for the assessment of the diagnostic performance of Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system for Pancreatic cysts. Safety and technical feasibility have already been performed, and an interpretation criteria classification exists. On the other hand, results for pancreatic masses, Lymph nodes and GIST are less developed.

the objectives of the study are to

  • Assess the diagnostic performance of the Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system in diagnosing masses and cystic tumors of the pancreas, lymph nodes, submucosal lesions of the GI tract
  • Define/Validate descriptive criteria of nCLE sequences in masses and cystic tu-mors of the pancreas, lymph nodes, submucosal lesions of the GI tract

Condition Intervention
Pancreatic Cyst Pancreatic Neoplasms Pancreatic Adenoma Pancreatic Cancer Pancreatic Islet Cell Tumors Lymph Node Mass Lymphadenopathy GIST Device: Endoscopic ultrasound fine needle aspiration

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 1 Year
Official Title: Registry Trial for Clinical Evaluation of nCLE in Masses and Cystic Tumors of the Pancreas, Lymph Nodes, Submucosal Lesions of the GI Tract

Primary Outcome Measures:
  • performance evaluation [ Time Frame: up to one year ]
    • Assess the diagnostic performance of the Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system in diagnosing masses and cystic tumors of the pancreas, lymph nodes, submucosal lesions of the GI tract (accuracy evaluation)
    • Define/Validate descriptive criteria for nCLE sequences in the characterization of masses and cystic tumors of the pancreas, lymph nodes, submucosal lesions of the GI tract (image interpretation criteria definition


Secondary Outcome Measures:

Groups/Cohorts Assigned Interventions
pancreatic cysts
Patient indicated for a first endoscopic ultrasound fine needle aspiration (EUS-FNA) for a pancreatic cyst,
Device: Endoscopic ultrasound fine needle aspiration
Device: nCLE needle-based Confocal Laser Endomicroscopy
Other Names:
  • ultrasonographic endoscopy
  • EUS-guided FNA

Detailed Description:

The principle of needle-based Confocal Laser Endomicroscopy (nCLE) is to image organs within or adjacent to the GI or respiratory tracts by means of a miniprobe inserted through an endoscopic needle. The fundamental technology, as well as the principle of operation of nCLE, is substantially similar to pCLE.

endoscopic fine needles are used during EUS-FNA procedures to puncture solid organs such as the pancreas, in order to get tissue or fluid for diagnostic purposes. There are different calibers of endoscopic nee-dles used. The most commonly used calibers for EUS-FNA procedures are 22G, 19G, and 25G needles. The nCLE Confocal Miniprobe is compatible with the 19G-type needle only. It is expected to help to differentiate the different types of lesions, especially for cysts, leading to better patient management. Microscopic tissue information in real-time in vivo during an EUS-FNA procedure may allow better differentiation between mucinous and non-mucinous cysts for instance.
