extended pathologic analysis of excised lymph nodes.

routine inguinal exploration in the absence of radiotracer visualization.

intraoperative palpation of the wound for abnormal nodes.

use of an ultrasensitive gamma ray detection probe.

The transposition of the sartorius muscle is eliminated.

Decreased morbidity.

The node dissection excludes regions lateral to the femoral artery and caudad to the fossa ovalis.

The required incision is longer.

The saphenous vein is preserved.

A laparoscopic approach has not been reported.

The saphenous vein may be preserved in the setting of low-volume disease.

The fascia lata remains intact.

The femoral nerve is visualized superior to the iliacus fascia.

Rotation of the gracilis muscle is performed to cover the exposed femoral vessels.
