Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study investigates the feasibility and the efficacy to treat pancreatic solid lesions as pancreatic adenocarcinomas (PDAC) and neuroendocrine tumors (NET) with ex-vivo radiofrequency ablation (RFA) under ultrasound (US) control.

The study intent is to define the optimal radiofrequency ablation POWER of the system in terms of maximum sizes (diameters) of histological coagulative necrosis obtained at pathological samples. Results will be useful to define the optimal settings to ablate pancreatic solid lesions (PDAC and neuroendocrine tumours).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A probe specifically designed for Endoscopic Ultrasound (EUS) in vivo treatment of human pancreatic solid masses will be used. The probe is connected to a radiofrequency generator on which the power can be set and the tip of the probe (on the tip is present the radiofrequency electrode) is continuously perfused by chilled solution. The generator can stop the power supply when the tissue impedance goes beyond the threshold value to prevent tissue carbonization
