Study: NCT05368090

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: EUS-RFA of left adrenal tumour in PA with AVS-verified left lateralisation
Description: Patients will fast, receive prophylactic antibiotics and conscious sedation prior to the endoscopic procedure.The procedure is performed with a standard linear echo-endoscope with a 3.7 mm or larger working channel. The left adrenal is identified from the fundus of the stomach. Color-Doppler is used to map adrenal vascularity. Ultrasound contrast is used to demarcate the border of the tumour. EUS-guided fine needle tissue sampling from tumour tissue is performed. The RFA ablation catheter is water-cooled and stable temperature is maintained at 70-75 degrees celsius until formation of heat bubbles can be seen on EUS. If necessary, the procedure is repeated after moving the probe until the whole adenoma volume is ablated. Ultrasound contrast medium is used after the procedure to ensure that the target for the ablation is non vascularized, before termination. The patients will be observed at the postoperative unit a few hours, and further in the ward for 24h
