Figure 2

Intestinal blood perfusion in the case of side-to-side anastomosis. Panels (A,F) are color photographs of patient’s intestines before and after anastomosis, respectively. Spatial distributions of the APC before and after anastomosis overlaid on the respective intestine images are shown in Panels (B,E), respectively. Points M1 and M2 mark the boundaries of visible vascularization and mesenteric attachment, respectively. The color bars in the bottom of Panels (B,E) show APC percentagewise. Panels (C,D) and (G,H) demonstrate PPG pulses in selected ROIs before and after anastomosis, respectively. The meaning of the graphs in these panels is the same as in Fig. 1.
