| Description | Gastrointestinal surgery is used in the treatment of diseases of body parts involved in digestion. This includes the esophagus, stomach, small intestine, large intestine, and rectum. It also includes the liver, gallbladder, and pancreas. To perform surgical treatment successfully, tissue blood perfusion must be precisely evaluated. An important procedural part of the surgery involves an anastomotic reconstruction, where the visualization of adequate blood perfusion on the free edges of the tissue needs to be verified before suturing the two ends of the tissue. Inadequate perfusion may affect the healing process due to, for example, anastomotic leak. Only a few objective methods for monitoring blood supply of the tissue during surgery treatment are commonly used. The aim of the study is was to integrate non-contact thermography (IRT) as an imaging technique for the detection of tissue blood perfusion during gastrointestinal surgery, in particular during tumor resection and subsequent reconstruction. The IRT method was supported by indocyanine green fluorescence imaging (ICG), which is used as a gold standard method to confirm the blood circulation in tissue. |
