title: Surgical management of Cushing's syndrome with emphasis on adrenal autotransplantation.
abstract: Cushing's syndrome may be caused by pituitary ACTH, ectopically produced ACTH, adrenocortical tumor or medication. Cushing's disease, due to excessive pituitary ACTH resulting in adrenocortical hyperplasia, remains a complex endocrine disorder for which no single treatment is wholly satisfactory. Twenty-two patients with surgically treated Cushing's syndrome are presented: Four with benign adrenocortical adenoma, two with adrenocortical carcinoma and 16 with adrenocortical hyperplasia. The four benign adenomas were excised with the one death due to respiratory failure and sepsis. Both patients with carcinoma and liver metastases died of their tumors. Of the 16 patients with adrenocortical hyperplasia and Cushing's disease, eight underwent subtotal adrenalectomy and thereafter eight had total intra-abdominal adrenalectomy with autotransplantation of adrenal tissue to the thigh. There was one operative death. Total adrenalectomy has now replaced subtotal resection in most clinics. All eight of the patients who had adrenal autotransplantation exhibited biopsy or functional evidence of some degree of graft survival. On patient stopped steroid replacement permanently and another developed recurrent Cushing's syndrome from the grafts. Of a total of 26 reported patients with adrenal autotransplants surveyed, 22 exhibited evidence of graft survival, 16 were able to discontinue steroid replacement therapy and three eventually developed recurrent Cushing's syndrome from the transplants. There is now strong evidence that most patients with Cushing's disease harbor a pituitary basophil ademona, and in the future the initial surgical attack may be directed to the pituitary rather than to the adrenals.
