Anesthesia and laparoscopic adrenalectomy for primary aldosteronism.

Adrenalectomy is the curative treatment of primary aldosteronism or Conn's syndrome. Laparoscopic adrenalectomy, a new method, should result in less pain and shorter hospitalization. We reported 25 patients who received anesthesia and laparoscopic adrenalectomy from 1995-1999. There were 17 females and 8 males. The mean age was 41.9 years (range 25-59). Ninety-six per cent had hypertension, 76 per cent had weakness of the extremities. When these patients sought medical care, their serum potassium and bicarbonate were 2.4 and 30.9 mEq/l respectively. Before operation, after treatment with spinorolactone, they were 4.3 and 24.4 mEq/l respectively. Associated diseases and cardiovascular abnormalities were reported. General anesthesia was the anesthetic technique of choice. Laparoscopic adrenalectomy was described in detail. Sixteen patients had adenomas on the left adrenal gland, 9 were on the right. Twenty-four patients had unilateral adrenalectomy, one had enucleation of the tumor. The size of the adenoma was 1.8 cm (range 1-3). There was no morbidity or mortality. All patients were discharged on the third postoperative day.
