About this trial
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.
