OBJECTIVETo investigate the standardized skill of mastoscopic axillary lymph node dissection (MALND).

METHODSThe clinical results and operation experiences of 473 mastoscopic lymph node dissections performed were analyzed.

RESULTThe operation time was 22 - 156 minutes with the average of 42. The operative bleeding was minimal. No case was converted to conventionally open operation because of the uncontrolled bleeding. Fourteen (4 - 38) lymph nodes were removed. There was no intra- or post-operative complication.

CONCLUSIONThe special view of mastoscopic lymph node dissection makes operative dissection clear. The suitable procedure and standardization of the operative method can stride over the learning curve, so as to quicken the operation and avoid the operative complication.
