Commentary on JPRAS-D-18-00185: The Use of Laser Speckle Contrast Imaging to predict flap necrosis - an experimental study in a porcine flap model Article

The authors need to be congratulated for their fine study on the use of Laser Speckle Contrast Imaging (LSCI) to predict flap necrosis in an experimental setting with a porcine pedicled flap model. LSCI has been repeatedly described for perfusion analysis in flap surgery. There has always been a demand to simplify or optimize intra- and postoperative flap monitoring, especially in free flap surgery. However, the individual techniques to postoperatively monitor free flaps vary considerably. In former studies from the early 1990ies with questionnaires ninety percent of microsurgeons reported to routinely use monitoring devices, with external and laser doppler having achieved greatest popularity.
