Endoscopic ultrasound-guided radiofrequency ablation for adrenal tumors in primary aldosteronism

Endoscopic Ultrasound-guided Radiofrequency Ablation as a Novel Treatment Option Compared With Adrenalectomy in Left-sided Primary Aldosteronism

Not applicable Interventional Haukeland University Hospital · NCT05368090

This study is testing a new non-surgical treatment using ultrasound to see if it can help people with primary aldosteronism and adrenal tumors feel better compared to traditional surgery.

What this trial studies

This study investigates the use of endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) to treat left-sided adrenal tumors in patients with primary aldosteronism and mild autonomous cortisol secretion. Participants will be divided into groups based on their specific conditions and the presence of adrenal tumors, with outcomes evaluated against control groups undergoing traditional adrenalectomy. The study aims to assess both clinical and biochemical outcomes, as well as the safety of the EUS-RFA procedure. By targeting adrenal tumors non-invasively, the study seeks to provide an alternative treatment option for patients who may not qualify for surgery.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 80 with confirmed primary aldosteronism or mild autonomous cortisol secretion and specific adrenal tumor characteristics.

Not a fit: Patients with bilateral adrenal overproduction or those who do not meet the inclusion criteria for the study may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this approach could offer a less invasive treatment option for patients with primary aldosteronism, potentially reducing complications associated with traditional surgery.

How similar studies have performed: While the use of EUS-RFA is a novel approach in this context, similar techniques have shown promise in treating other conditions, indicating potential for success.
