Intraoperative Control of Hemoglobin Oxygen Saturation in the Intestinal Wall during Anastomosis Surgery

During surgery for colon cancer, monitoring of the oxygen saturation hemoglobin in tissues under study makes it possible to assess degree blood supply anastomosis areas colon. Adequate this area is decisive terms consistency and can significantly reduce risk leakage anastomosis. In work, we propose a new approach assessing based on measuring both diffuse reflectance transmittance spectra wall tissues. The proposed method use two fiber-optic tools irradiation from sides—the intestinal lumen outside wall. are recorded external side. To determine saturation, algorithms, Taylor series expansion coefficient light attenuation by tissues, proposed. results clinical volunteers were obtained, allowing draw conclusion about applicability setting.
