INTRAOPERATIVE ICG FLUORESCENCE ANGIOGRAPHY: ANALYSIS OF FIRST RESULTS IN OUR SINGLE-CENTER

Abstract

Abstract INTRODUCTION Anastomosis dehiscence is one of the most serious complications in colorectal surgery, influenced by many factors, especially the anastomotic ischemia. Intraoperative Indocyanine Green (ICG) Fluorescence Angiography allows to assess the vascular perfusion of the ends anastomotic and anastomosis thus seeking to decrease the number of sutures failure. MATERIAL AND METHODS A retrospective and descriptive study of patients undergoing colorectal surgery in our centre using intraoperative indocyanine green fluorescence angiography. We analysed a total of 45 patients, including 40 cases of colorectal cancer and 5 cases with a benign pathology (4 diverticular disease and 1 Crohńs disease). RESULTS After administration of ICG, the site of resection was changed in 6 cases due to bad perfusion findings. 5 patients presented anastomotic leakage during the postoperative period. The medium hospital stay length was 10 days, increasing to 29,2 days medium stay in patients with postoperative dehiscence respect to 7’72 days in patients without postoperative complications. No deaths or adverse reactions associated with the ICG were detected. CONCLUSIONS The technique with ICG seems to be a promising tool for the colorectal surgery as a predictor of suture failure. It allows a reduction of hospital stay length and postoperative morbidity and mortality from this cause and it can serve as a good help for making decisions in the course of a surgery.
