Evaluation of large colon viability using sidestream dark field microscopy in horses with colic
The goal of this study is to investigate a new technology called Microscan, a hand-held dark-field microscope which would allow veterinarians to evaluate the blood supply to the large colon of horses during surgery. This would help deciding how much of the colon is still viable and therefore decreasing the chances of unnecessary radical resection (colon tissue removal). The microscan results will later be correlated with standard biopsy for validation. All that is required for this study is a small biopsy of the colon during surgery and permission to obtain images with Microscan.
