Laparoscopic fluorescence navigation for left-sided colon and rectal cancer: Blood flow evaluation, vessel and ureteral navigation, clip marking and trans-anal tube insertion

摘要

Background: Recently, the indocyanine green (ICG) fluorescence navigation method has attracted much attention as a means of intraoperative navigation, especially during laparoscopic surgery. The newly developed nearinfrared (NIR) fluorescent resin also emits NIR fluorescence, as does ICG. Presently, new devices made with this resin are being developed. The purpose of this study was to present our fluorescence navigation techniques for left-sided colon and rectal cancer.
