Cushing's syndrome: adrenalectomy and long-term results.
BACKGROUND
The objective of this study was to assess the preoperative symptoms, intra- and postoperative complications and follow-up in patients after uni- or bilateral adrenalectomy due to Cushing's syndrome (CS), independent of etiology.


METHODS
Clinical charts of 42 patients (5 with ACTH-dependent, 37 with ACTH-independent CS) were reviewed, and follow-up data were obtained from re-examination of the patients.


RESULTS
The symptoms most frequently seen were hypertension, changes of the skin and obesity. Eight bilateral and 36 unilateral adrenalectomies were carried out without any intraoperative complications. Postoperative complications occurred in 5 patients, 1 patient died on the fourth postoperative day. After a mean duration of 4.6 years 28 of 41 patients could be re-examined, 5 patients had died. One patient showed recurrence 4.3 years after unilateral adrenalectomy due to nodular hyperplasia, contralateral adrenalectomy again revealed nodular hyperplasia.


CONCLUSIONS
Early diagnosis is essential in order to decrease the rate of pre-, intra- and postoperative complications. Endoscopic approach should be taken in a specialized center due to poor patient's condition. Recurrent disease on the contralateral side may represent bilateral adrenal hyperplasia with sequential tumor formation, demonstrating the importance of extensive preoperative biochemical and imaging testing and close follow-up.
