Primary Intrapelvic Lymphaticovenular Anastomosis Following Lymph Node Dissection

In Brief Lymphedema of lower extremities occurs following surgical resection of malignant tumors and intrapelvic lymph node dissection and is a long-term problem for patients. We performed primary intrapelvic lymphaticovenular anastomosis to prevent postoperative leg lymphedema. The procedures were conducted in 7 patients (aged 35–61 years) with cancer of the uterine body. After completion of hystero-oophorectomy and intrapelvic lymph node dissection, the afferent lymphatics entering internal and external iliac lymph nodes were end-to-end anastomosed with branches of the deep inferior epigastric veins. The time taken for constructing 4 anastomoses was 100 to 120 minutes. The follow-up period ranged from 10 to 18 months (mean, 14 months). All patients were discharged and are independent in daily living. Apart from mild leg lymphedema in 1 patient, no lymphedema was observed in other patients up to the last follow-up. This surgical modality is effective in preventing lymphedema in lower extremities after intrapelvic para-aortic lymph node dissection. Seven patients undergoing total abdominal hysterectomy, salpingo-oophorectomy, and intrapelvic node dissection underwent simultaneous end-to-end anastomosis of the afferent lymphatics to branches of the deep inferior epigastric veins. Postoperative leg lymphedema was seen in only 1 of the 7 patients.
