Research and Innovation in Fluorescence Guided Surgery
Every field of surgery has seen an explosion of new technologies aimed at improving surgical technique and reducing complications. The use of near-infrared (NIR) fluorescence to assess perfusion has been described in several surgical disciplines. NIR provides the surgeon with real-time perfusion assessment of a target organ or anastomosis and can be invaluable in aiding decision-making during the index operation. In the following article we discuss the use of fluorescence-guided perfusion assessment during colonic interposition for esophageal replacement. To our knowledge this is the first description of the use of fluorescence-guided perfusion assessment during colonic interposition.
The assessment of the flap perfusion in reconstruction surgery is mostly based on clinical evaluation. Unfortunately, surgeons still face some risk of complications if the flap tissue is not well perfused. Indocyanine Green (ICG) angiography allows the surgeon to define the boundaries of the perforator perfusion zones of a flap with high sensitivity, avoiding partial flap loss and fat necrosis.
