    Abstract:
    OBJECTIVE: To describe the technique of endoscopic exploration of the axilla. To compare this technique to open surgical treatment by comparing the following variables: operative time, peri-operative complications, duration of hospital stay, node's histology and morphologic aspects and esthetic results. MATERIALS: Standard instruments for traditional operative laparoscopy plus a lipo-aspirator (0.8 Bar). PATIENTS: Forty patients, 20 (group A) undergoing open surgery and 20 (group B) undergoing axilloscopy. All patients with early invasive breast cancer are eligible for conservative operative treatment. METHOD: Randomized study. The technique is described and preliminary results are presented. RESULTS: The operative time for axilloscopy is approximately double that for open surgery. A comparable number of lymph nodes is collected by axilloscopy and open surgery. The nodes collected by axilloscopy are more likely to be fractured. What is the clinical consequence? Two loco-regional relapses are observed in the endoscopic group. DISCUSSION: Axillary sampling by endoscopic procedure gives the same pathologic information than surgical axillary sampling. Anatomo-pathologic aspects of nodes and possibilities of relapses were two drawbacks of this procedure. CONCLUSION: Operative time is increased for axilloscopy compared with open surgery. The techniques yield comparable anatomo-pathologic results. It is still unknown whether this endoscopic technique is as effective as traditional surgery or if the frequency or severity of lymphedema is decreased by the endoscopic approach.
