Assessing the blood supply of the bowel is a difficult task even for experienced surgeons. Laser-assisted indocyanine green (ICG) fluorescent dye angiography provides intraoperative visual assessment of blood flow to the bowel wall and surrounding tissues, allowing for modification to the surgical plan, which can reduce the risk of postoperative complications. ICG angiography was
prospectively performed in a single center during a 1-year period for small bowel ischemia and left colorectal resections.
ICG angiography played a major role in the intraoperative decision making in 4 of 160 patients, whose clinical and operative details are here reported. In case of acute small intestine ischemia, resection is not warranted unless absolute perfusion units are below 19 (relative 21 %). When evaluating blood supply to the left colon prior to anastomosing, resection is recommended with
absolute units lower than 18 (relative 31 %) even if the bowel appears macroscopically perfused.
