A (a) In the ascending to cecum, no changes in the serosal surface were observed with the naked eye. (b) Intraoperative ICG image showed a granular distribution of fluorescent dye, indicating “fine granular pattern”. B (a) Intraoperative findings showed no obvious intestinal necrosis. However, there was an area of dark red serosa at the terminal ileum (arrows). (b) ICG fluorescence was deficient except in perivascular area, indicating “perivascular pattern” (arrowheads)
