Fiber-optic near-infrared fluorescence spectroscopy using indocyanine green for semi-quantitative time–intensity curve assessment of the gastric conduit before and after retrosternal reconstruction: an initial clinical study

Takeo Nitta, Yuma Ebihara, Hironobu Takano, Saseem Poudel et autres

BACKGROUND: Adequate perfusion at the planned anastomotic site is important during gastric conduit reconstruction after esophagectomy. However, objective intraoperative assessment remains challenging. This pilot study evaluated the feasibility of fiber-optic near-infrared fluorescence spectroscopy using indocyanine green (ICG) and descriptively characterized local semi-quantitative …
