Abstract
BACKGROUND: Liposuction for International Society of Lymphology late stage 2 or 3 limb lymphedema is an established surgical option to remove excessive adipose tissue deposition and has been performed in Australia since 2012 at the Australian Lymphoedema Education, Research, and Treatment (ALERT) Program of Macquarie University. METHODS: Between May of 2012 and May of 2017, 72 patients with unilateral primary or secondary lymphedema of the arm or leg underwent suction-assisted lipectomy using the Brorson protocol. This prospective study presents 59 of these patients who had consented to research with a 5-year follow-up. RESULTS: Of the 59 patients, 54 (92%) were women, 30 (51%) had leg lymphedema, and 29 (49%) had arm lymphedema. For patients with arm lymphedema, the median preoperative volume difference between the lymphedematous and the contralateral arm was 1061 mL, which was reduced to 79 mL 1 year after surgery and to 22 mL 5 years after surgery. For patients with leg lymphedema, the median preoperative volume difference was 3447 mL, which was reduced to 263 mL 1 year after surgery but increased to 669 mL 5 years after surgery. CONCLUSION: Suction-assisted lipectomy is a long-term option for the management of selected patients with International Society of Lymphology late stage 2 or 3 limb lymphedema when conservative management can offer no further improvement. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
