Abdominoplasty with Lymphatic Microsurgery for Patients with Secondary Lower Extremity Lymphedema.

Background: Patients with secondary lower extremity lymphedema (LEL) often develop suprapubic lymphedema. We developed a novel surgical method of shaping the lower abdomen and debulking suprapubic lymphedema with simultaneous reconstruction of lymphatic flow in case of LEL. Methods: A skin incision in a fleur-de-lis pattern was performed for horizontal and vertical abdominal skin and fat resection. A caudal-based isosceles triangular flap was created on the central suprapubic region to reduce wound tension at the intersection of the horizontal and vertical incisions. After resection and debulking of the suprapubic region, a lymphaticovenular anastomosis (LVA) between the efferent lymphatic vessel of the groin node and the superficial inferior epigastric vein was created or vascularized lymph node transfer (LNT) to the groin region was performed to restore lymphatic flow. LVA and LNT were also performed at the lower extremities to improve LEL. Perioperative change in limb volume was evaluated using the LEL index, and lymphatic function was evaluated by lymphoscintigraphy. Results: Simultaneous abdominoplasty and reconstructive lymphatic microsurgery were performed in 11 patients. The LEL index improved perioperatively, with a significant difference (p
