The laparoscopic right gastroepiploic lymph node flap transfer for upper and lower limb lymphedema: Technique and outcomes.

BACKGROUND

Lymph node flap transfer popularity for treatment of extremity lymphedema is increasing quickly. Multiple flap donor sites were described in search of the optimal one. We describe the technique and outcomes of a laparoscopically harvested right gastroepiploic lymph node flap for treatment of extremity lymphedema.

METHODS

From January 2012 to January 2013, 10 consecutive female patients, average age 54.8 years, with International Society of Lymphology stage II-III extremity lymphedema refractory to conservative management were included. Five patients had upper limb breast cancer-related lymphedema and five patients had lower limb pelvic cancer-related lymphedema. All patients underwent laparoscopic harvest of the right gastroepiploic lymph node flap, transferred to the wrist and ankle as recipient sites. Flaps were covered with a small skin graft taken from the thigh. Perioperative assessment included physical exam, photography, circumference measurements, CT scans, lymphoscintigraphy, and Lymphedema Quality of Life (LYMQOL) questionnaire. Clinical and CT evaluation of donor-site morbidity were performed.

RESULTS

The flap survival rate was 100%, with a mean harvest time of 32 minutes and total operating time of 164 minutes. One case required regrafting for skin graft loss. The mean limb reduction rate was 39.5% at a mean follow-up of 14.7 months. Perioperative lymphoscintigraphy demonstrated transferred lymph node viability and lymphatic transport improvement. LYMQOL showed a 2.6-fold quality-of-life improvement (P < 0.01). No donor-site morbidity was encountered.

CONCLUSIONS

The use of the laparoscopically harvested right gastroepiploic lymph node flap may be a safe technique that improves limb measurements and quality of life in extremity lymphedema patients. © 2015 Wiley Periodicals, Inc. Microsurgery 37:197-205, 2017.
