title: Long-term results of adrenal surgery in patients with Cushing's syndrome due to adrenocortical adenoma.
abstract: Fourteen of 16 patients with Cushing's syndrome due to adrenal adenoma who had undergone adrenal surgery in the period 1967-1981 participated in a follow-up study 1 to 15 (mean 4.5) years after the operation. There were 14 unilateral and two bilateral adenomas. Two patients have died: one from postoperative complications, the other by suicide 10 years after surgery. None of the patients relapsed and none showed clinical features of Cushing's syndrome. However, five patients remained obese and four hypertensive. Furthermore, in the female patients the bone mineral density was lower than in age-matched controls. The function of the pituitary-adrenal axis recovered slowly. Postoperative replacement therapy was withdrawn 3 to 28 (mean 11.8) months after surgery in all but one patient. The function of the remaining adrenal gland was completely normal in 10 patients. In two patients the plasma cortisol response to ACTH-stimulation was still blunted and associated with elevated plasma ACTH-levels. The plasma ACTH-level was low in the only patient having persistent hypocortisolism. In conclusion, the results show that most patients with Cushing's syndrome due to adrenal adenoma recover fully after surgery. In some patients, however, the suppressed pituitary and/or adrenal fail to resume normal function.
