Objective: Surgical resection of a part of the intestine is a standard procedure in gastrointestinal surgery and in order to perform this type of surgery successfully, tissue blood flow must be evaluated clearly. There exists a theoretical indication that it would be possible to use infrared thermography (IRT) for this purpose. Therefore, the main objective of the study is the qualitative evaluation of the infrared thermography method as an ancillary method for determining the resection lines and forming an optimal intestinal anastomosis on the porcine model. Approach: Blood circulation rate has a close relationship with temperature difference and is also very important for identifying the resection lines on the bowel, the formation of anastomoses, and, subsequently, their adequate healing. Therefore, IRT could be helpful in determining the nonvascular part of the intestine. In order to make a qualitative evaluation of this method, the study also focuses on a comparison of IRT with the contrasting indocyanine green (ICG) imaging method, which is commonly used. Main results: The comparison of two independent imaging methods (IRT and ICG) revealed similar, but not identical, results. Subjective evaluation of the anastomosis performed by the team of three surgeons was more in agreement with the area detected by contactless thermography imaging. Moreover, the proceeding ‘dynamic temperature return test’, when the particular intestinal part was cooled and its subsequent temperature return was measured, revealed significant results. The time taken to return to the original intestinal temperature was greater for the devascular part of the intestine. Significance: A thermographic examination could help to detect the correct location of the intestine resection line for further/continuing anastomosis creation.
