2 Figure 1 Schema of the evaluation point of the gastric tube with indocyanine green angiography. (A) Two evaluation points of the gastric tube: Point A (circle), the last branch of the right gastroepiploic artery; Point B (square), 3 cm proximal from Point A. (B) Monitoring of LumiView. Average luminance at each point is displayed in the upper right, and change of luminance is displayed below.

3 Figure 2 Time course of change in luminance. Lmax, difference between maximum and baseline luminance; T-b, baseline time, time between indocyanine green injection and increase in luminance; T-in, inflow time, time from increase in luminance to maximum; T-out, outflow time, time from maximum luminance to 20% attenuation from maximum value.
