Summary
In this study, the investigators will perform endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) treatment of left-sided adrenal tumours in patients with primary aldosteronism (PA) and in patients with mild autonomous cortisol secretion (MACS). Four different study groups will all receive EUS-RFA of left-sided adrenal tumours. Clinical and biochemical outcome as well as procedural safety will be evaluated. In study patients with verified lateralised aldosterone or cortisol overproduction to the left adrenal, outcome will be compared with control groups performing conventional unilateral adrenalectomy. Study group 1: PA patients with AVS-verified left sided lateralisation and a EUS-detectable tumour in the left adrenal for EUS-RFA treatment. Study group 2: PA patient with suspected left-sided overweight of aldosterone production and a EUS-detectable tumour but without strict lateralisation of their aldosterone overproduction, for EUS-RFA treatment as an aldosterone "debulking" procedure. Study group 3: patients with MACS with AVS-verified lateralisation of cortisol overproduction to the left adrenal and EUS-detectable tumour for EUS-RFA treatment Study group 4: patients with MACS with bilateral adrenal tumours and verified bilateral overproduction of cortisol for EUS-RFA treatment as a cortisol "debulking" procedure.

Interventions
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
