Bilateral adrenalectomy for Cushing's syndrome: a comparison between laparoscopy and open surgery.

We report our experience with bilateral adrenalectomy for treatment of Cushing's syndrome and we compare the outcome of laparoscopy with open surgery in terms of effectiveness and safety. A series of 23 patients underwent bilateral adrenalectomy for treatment of Cushing's syndrome [Cushing's disease in 16, ectopic ACTH syndrome in 2, and ACTH-independent macronodular adrenal hyperplasia (AIMAH) in 5 cases]. From 1993 to 1996, all patients were treated using an open approach (Group A), while from 1997 all patients were treated using a transperitoneal laparoscopic approach (Group B). The comparison between the 2 groups was performed considering patients characteristics, operative times, blood losses, intraoperative and post-operative complications, analgesic consumption, post-operative hospital stay and recovery. Open surgery was performed in 10 patients and laparoscopy in 13 patients. No significant difference was recorded between the two groups as to patients' characteristics and complications. Mean operative time was significantly increased in Group B, while post-operative hospital stay was significantly longer in Group A. Laparoscopic bilateral adrenalectomy can be safely and effectively employed to treat Cushing's syndrome. However, long operatives times may represent a limitation especially in high risk patients.
