Between March and June 1994 three adrenalectomies were performed via an endoscopic extraperitoneal approach. After creating a carbon dioxide retropneumoperitoneum three 10 mm trocars were introduced in the area of conventional lumbar incision. Via these ports adrenalectomy was performed. Time of operation amount to 215, 290 and 330 min. No postoperative complications were observed. Time of postoperative hospitalisation amount to 3, 4 and 7 days. The advantage of the extraperitoneal approach is that it decreases postoperative pain and allows more rapid recovery.
