Assessment of the blood supply using the indocyanine green fluorescence method and postoperative endoscopic evaluation of anastomosis of the gastric tube during esophagectomy

Postoperative anastomotic leakage is a severe complication after gastric tube reconstruction during esophagectomy. The aim of this study was to evaluate the usefulness of postoperative endoscopic assessment of anastomosis and its correlation with intraoperative indocyanine green (ICG) fluorescence assessment of the gastric tube. We retrospectively reviewed 72 consecutive patients who underwent gastric tube reconstruction using the ICG...
