Laparoscopic adrenalectomy. The importance of a flank approach in the lateral decubitus position.

Adrenalectomy is usually performed via transabdominal or posterior approaches. Unfortunately, both approaches are associated with painful postoperative syndromes. Recently, laparoscopic surgery was applied to organ removal. During a period of 12 months, we performed a series of successful laparoscopic adrenalectomies (10 of the right and 11 of the left gland). The pathologies were medullary cyst (1), angiomyolipoma (1), DHEAS hyperplasia (1), primary aldosteronism (2), Cushing's adenoma (3), pheochromocytoma (4), Cushing's syndrome (4), and nonfunctional adenoma (5). A flank approach was taken with four 11-mm trocars. Electrocautery and blunt forceps were used for dissection. The vessels were secured with medium-large titanium clips, and the adrenal was removed in a sterile plastic bag. The average operating time was 2.3 h, and median postoperative stay was 4 days. Two patients required blood transfusion of 2 units postoperatively. We believe this technique is adequate for the surgical removal of adrenal tissue, resulting in less postoperative pain and in rapid recovery. It may also change the surgical management of asymptomatic adrenal lesions.
