Conn's syndrome, an aldosterone producing adenoma, is a surgically curable cause of primary aldosteronism, classically treated by unilateral adrenalectomy. With the advent of laparoscopic surgery in recent decades, laparoscopic adrenalectomy is currently advocated as the gold standard for the treatment of Conn's syndrome. Cortical sparing adrenalectomy is an especially ideal operation for patients with bilateral pheochromocytoma. This case report describes a successful laparoscopic adrenal cortex sparing surgical and anaesthetic approach for a patient with Conn's syndrome on whom right surrenalectomy had been performed previously. Laparoscopic surgery without dividing the central adrenal vein can also be performed successfully in patients with Conn's syndrome. © Copyright 2013 by Turkish Surgical Association.
