Retroperitoneoscopic adrenalectomy: lateral versus posterior approach.

PURPOSE

We used a lateral or posterior approach to perform retroperitoneoscopic adrenalectomy for adrenal tumors and compared the results to determine which approach is more advantageous.

PATIENTS AND METHODS

We removed 42 adrenal tumors from 42 patients by retroperitoneoscopic surgery. We used the posterior approach in 17 cases and the lateral approach in 25 cases. We compared the operating time, complications, and surgical advantages for the two approaches.

RESULTS

The mean operating time was significantly shorter with the lateral approach, 141 +/- 64 minutes v 225 +/- 88 minutes for the posterior approach (P = 0.0019), which we believe reflects the technical advantages of the lateral approach. Complications included one case of pneumothorax and an instance of pulmonary edema in a patient with chronic renal failure using the lateral approach and one occurrence each of pneumothorax and bleeding using the posterior approach. Retroperitoneoscopic adrenalectomy could not be performed in 1 of 25 cases (4.0%) using the lateral approach and in 3 of 17 cases (17.6%) using the posterior approach.

CONCLUSION

Our series suggests that the lateral approach is preferable to the posterior approach for retroperitoneoscopic adrenalectomy.
