Video endoscopic inguinal lymphadenectomy (VEIL): minimally invasive resection of inguinal lymph nodes.
OBJECTIVE
Describe and illustrate a new minimally invasive approach for the radical resection of inguinal lymph nodes.


METHODS
From the experience acquired in 7 operated cases, the video endoscopic inguinal lymphadenectomy (VEIL) technique was standardized in the following surgical steps: 1) Positioning of the inferior member extended in abduction, 2) Introduction of 3 work ports distal to the femoral triangle, 3) Expansion of the working space with gas, 4) Retrograde separation of the skin flap with a harmonic scalpel, 5) Identification and dissection of the long saphenous vein until the oval fossa, 6) Identification of the femoral artery, 7) Distal ligature of the lymph node block at the femoral triangle vertex, 8) Liberation of the lymph node tissue up to the great vessels above the femoral floor, 9) Distal ligature of the long saphenous vein, 10) Control of the saphenofemoral junction, 11) Final liberation of the surgical specimen and endoscopic view showing that all the tissue of the region was resected, 12) Removal of the surgical specimen through the initial orifice, 13) Vacuum drainage and synthesis of the incisions.


CONCLUSIONS
The VEIL technique is feasible and allows the radical removal of inguinal lymph nodes in the same limits of conventional surgery dissection. The main anatomic repairs of open surgery can be identified by the endoscopic view, confirming the complete removal of the lymphatic tissue within the pre-established limits. Preliminary results suggest that this technique can potentially reduce surgical morbidity. Oncologic follow-up is yet premature to demonstrate equivalence on the oncologic point of view.
