title: Laparoscopic adrenalectomy: a report on 50 operations.
abstract: OBJECTIVE
  To investigate the feasibility, safety and results of laparoscopic transperitoneal adrenalectomies performed with the patient supine, in patients affected by secreting and silent adrenal lesions.
  
  
  METHODS
  Exclusion criteria were suspected adrenal primary malignancies. Fifty patients (33 women and 17 men; mean age 49.6 years, range 19-75 years) underwent 51 laparoscopic adrenalectomies (one bilateral). After complete endocrinological evaluation, computed tomography or magnetic resonance imaging, or a combination thereof, 14 non-secreting adenomas, 13 aldosterone-producing adenomas, 13 cortisol-producing adenomas, eight phaeochromocytomas (one bilateral), one androgen-secreting adenoma, and two metastases were considered eligible for adrenalectomy. In five patients, associated procedures were performed during surgery.
  
  
  RESULTS
  The lesions ranged in size from 1.5 to 10 cm. There were no intraoperative complications and no blood transfusions were required. The postoperative course was uneventful and painless in all patients. Mean postoperative hospital stay was 2.5 days. In all hypertensive patients, significant improvement or cure of hypertension was observed at follow-up (mean 18 months). In patients with secreting adenomas, normalization of hormone concentrations was obtained after removal of the tumour. In six patients with incidentaloma, the exaggerated 17-hydroxyprogesterone response to ACTH disappeared after surgery.
  
  
  CONCLUSIONS
  Secreting and non-secreting adrenal lesions were treated safely by laparoscopy. Relatively small incidentalomas and subclinical hormonally active tumours can be removed by laparoscopy. Early diagnosis enhances prevention and treatment.
