Feasibility of laser speckle contrast imaging using the bowel perfusion assessment tool Lapvas-Imaging

Primary outcome(s): -The percentage of operating surgeons that indicated no change in location of the anastomosis based on the additional Lapvas-Imaging derived visual feedback;
-The percentage of the non-involved surgeons that indicated no change in location of the anastomosis based on the additional Lapvas-Imaging derived visual feedback;
-The proportion of the indication of a change in location by operating and non-involved surgeons between patients with and without AL;
-The homogeneity of the change in location between non-involved surgeons for individual patients;
-The estimated change in location of the anastomosis proximal/distal in centimeters by the treating surgeon;
-The estimated change in location of the anastomosis proximal/distal in centimeters by non-involved surgeons;
-A change in the location of the anastomosis by non-involved surgeons in comparison to the operating surgeon;
-Development of anastomotic leakage;
-Extra time taken for imaging during surgery (seconds)
