Background: Lymphedema (LE) is a serious complication of axillary lymph node dissection (ALND) with an incidence rate of 16%. Simplified Lymphatic Microsurgical Preventing Healing Approach (SLYMPHA) is a safe and relatively simple method, which decreases incidence of LE dramatically. Our initial study showed an 88% decrease in clinical LE rate. In the initial study, we used arm circumference measurement for the diagnosis of LE and median follow up was 15 months. The aim of this study was to confirm these results after a long-term follow up period and by using bioimpedance spectroscopy (L-Dex) technology in detecting LE. Methods: All patients, undergoing ALND with or without SLYMPHA between January 2014 and November 2020 were included in the study. Patients with no postoperative L-Dex measurements were excluded. A L-Dex score outside the normal range (± 10 L-Dex unit) or >10 L-Dex unit increase above patient’s baseline was considered as LE. The incidence of LE was compared between patients with and without SLYMPHA. Results: 194 patients were included in the study. 57% of cohort underwent SLYMPHA. Mean follow-up time was 47 ±37 months. Patients, who underwent SLYMPHA, had a significantly lower rate of LE (16% vs 32%; p=0.01; OR 0.4 [0.2-0.8]). Conclusions: SLYMPHA is a safe and relatively simple method, which continued its efficacy after a long-term follow up period. It should be considered as an adjunct procedure to ALND for all patients during initial surgery. [Table: see text]
