| ICG-FA | 52 | 10 789 | 5739 | 5050 | 238 (4.1) | 454 (9) | 533 (10.7) |

Values are n (%). †Average as opposed to total. Site relocation data consider only studies that documented the parameter. AL, anastomotic leak; ICG-FA, indocyanine green fluorescence angiography; DRS, diffuse reflectance spectroscopy; HSI, hyperspectral imaging; LSCI, laser speckle contrast imaging. Percentages may not total 100% due to rounding.
