Endoscopic ultrasound radiofrequency ablation of pancreatic insulinoma in elderly patients: Three case reports

Figure 1 Radiofrequency ablation system. A: Needle, similar to an endoscopic ultrasound fine needle aspiration or biopsy needle; B: Peristaltic pump which can infuse during the ablation, the electrode with chilled solution, maximizing volume ablation; C: Electrode on the distal needle tip, delivering radiofrequency ablation; D: Radiofrequency generator, with the possibility to monitor ablation parameters: Power, time, impedance.

Figure 2 Case 2 imaging. A: A hyper-vascularized lesion compatible with an insulinoma, extremely close to the gastroduodenal artery is visible; B: Submucosal bleeding after radiofrequency ablation, treated by endoscopic hemostasis; C: Computed tomography scan 72 h after radiofrequency ablation: An 8 mm hypodense necrotic area at the previous lesion location, without signs of bleeding.
