Abstrakt:	Background: In lymphedema, the accumulation of subcutaneous interstitial fluid is the most characteristic feature. Bioimpedance analysis (BIA) is a promising technique to measure the amount of body components using a noninvasive method. In this study, we determined the clinical significance of BIA parameters in upper limb lymphedema with surgical treatment such as lymphovenous anastomosis or vascularized lymph node transfer. Methods and Results: A single-center retrospective study using a multifrequency BIA. Perioperative BIA parameters such as extracellular water ratio or fat-free mass (FFM) ratio and limb volume defined as percentage of excess volume (PEV) were measured. The relationships between the magnitude of change in PEV and BIA parameters during surgery were evaluated. Out of 48 unilateral lymphedema patients, 46 were female and the average age was 55.4 years. PEV and all BIA parameters showed a significant decrease after surgery ( p < 0.001). There were significant correlations between ΔPEV and the degree of changes in all BIA parameters. ΔFFM ratio showed the highest correlation with the amount of change in PEV ( r = 0.599, p < 0.001). Conclusion: BIA parameters correlated well with the volume change after surgery. BIA could be useful as a quick and easy tool for follow-up after lymphedema surgery.
