Laparoscopic adrenalectomy via the retroperitoneal approach: first five cases.

Between February and November 1994, we performed laparoscopic retroperitoneal adrenalectomy in five patients with benign adrenal tumors to confirm the efficacy of this operation. Using digital dissection and a balloon, we created a working space in the retroperitoneal cavity before we dissected the adrenal gland and removed it under laparoscopic observation. The adrenal glands of all five patients were removed without any complications. The mean operative time was 3.4 hours, and the mean estimated blood loss was 148 mL. The average postoperative hospital stay was 10 days, and the average full recovery time was 19 days. We concluded that the retroperitoneal approach is an advantageous and safe procedure in the laparoscopic removal of the adrenal gland with benign tumor.
