Surgical management of Cushing's syndrome.

Twenty-seven operations for Cushing's syndrome were reviewed. Included were five cases of adenoma and 22 of adrenal cortical hyperplasia. Preoperative laboratory data, particularly the metyrapone test, were highly accurate in distinguishing adenoma from hyperplasia. Bilateral flank incisions are preferable to the transabdominal approach, with fewer complications, less postoperative ileus, and shorter hospital stays. The inability to inspect both glands simultaneously is of little consequence because biochemical testing data are sufficiently accurate to obviate the need for gross evaluation. The use of perioperative prophylaxis seems to be of importance for preventing thromboembolism in these hypercoagulable patients. The preoperative use of adrenal cortical blocking agents has not proved to yield significant advantages.
