NCT06315439

Brief Summary

Endoscopic ultrasound-guided (EUS) tissue acquisition is the current standard of care for the diagnosis of pancreatic solid lesions but it is burdened by a non-negligible risk of non-diagnostic or inconclusive results. Ex-vivo fluorescence confocal laser microscopy (FCM) with MAVIG VivaScope® 2500M-G4 could allow real time assessment of adequacy and diagnosis of the sample.

Outcome Measures

Primary Outcomes (1)

  • Diagnostic accuracy

    To evaluate the accuracy of fluorescence confocal microscopy (FCM) for ex-vivo examination of samples obtained from EUS- FNA/B in pancreatic solid lesions to assess final diagnosis against final histological diagnosis.

    baseline

Study Arms (1)

pancreatic solid lesions

Procedure: Endoscopic ultrasound fine needle biopsy

Interventions

Endoscopic ultrasound fine needle biopsyPROCEDURE

EUS FNA/B for solid pancreatic lesions. After the FNA/FNB, the needle was removed from the EUS endoscope and the specimen obtained after the first needle pass was expelled and placed directly in a dedicated scaffold (Cytomatrix, UCS Diagnostics). a drop of ethanol was put on it and the liquid was drained away thanks to the porous structure of the matrix. This step was followed by the deposition of a drop of acridine-orange for 20" and a rapid washing with buffered saline. After that, the Cytomatrix was put on a dedicated microscopic slide and covered with a second slide before the introduction in the slot of the machine. The FCM VivaScope® 2500 (2500M-G4; VivaScope, Munich, Germany) was used for immediate imaging.
