Gynecologic malignancies, especially cervical, endometrial, and vulvar cancers, mainly progress by lymphatic metastasis, and therefore, systematic lymph node dissection is performed in many patients. On the other hand, the rates of lymph node metastasis in pT1 and pT2 patients are about 15.8% in cervical cancer, 5.9% in endometrial cancer, and 25% in vulvar cancer [1, 2]. Therefore, the decrease in QOL due to postoperative lymphedema and lymphatic cysts caused by lymph node dissection is becoming a growing issue corresponding to the improvement of long-term outcomes.
