摘要
FIELD: medicine.;SUBSTANCE: invention relates to medicine, specifically to oncology, and can be used for prediction of risk probability of development of anastomotic breakdown in post-surgery period at patients suffering with oesophageal cancer. On the preoperative stage involves a computer tomography examination of stomach in native mode and with bolus contrast enhancement of the image. Densitometrical indicators of density are consistently measured in the fixed points of forestomach, middle third of the body at large curvature and antral stomach. Dynamic curves of stomach wall density are built depending on a phase of contrast amplification and anatomical portion of a stomach. In case of increase of stomach wall density with the peak of contrast in arterial phase of not more than 90 HU, shift of peak contrast enhancement in portal or venous phase with values, which do not exceed 70 HU and 80 HU respectively, in combination with locus character of contrast and blurring of boundaries between muscular and mucosal layers of stomach wall in an arterial phase of contrasting predict high probability of the risk of development in post-surgery period of failure of esophagogastric anastomosis.;EFFECT: method allows to carry out the accurate and informative prediction, and also to reduce the frequency of postoperative complications due to carrying out computer and tomographic analysis of stomach and creation of dynamic curves of density of stomach wall depending on a phase of contrast amplification and anatomical portion of stomach.;1 cl, 3 dwg, 1 ex
