Dynamics of changes in clinical blood parameters in patients in the early postoperative period with gastroesophageal cancer during nutritional support

Perioperative nutritional support is one of the important components of complex surgical treatment of the esophagus and stomach. According to various authors, protein-energy deficiency in cancer patients in 20–80 % of cases with cancer reduces body weight – an independent predictor of permanent continuation of the disease. Surgery, as one of the treatment methods, which is the strongest stressor, causes catabolic reactions, significantly increasing the loss of protein and energy in patients. However, at present, the need to prescribe artificial nutrition in the perioperative period is questioned and there is no consensus on artificial nutrition in the perioperative period. Numerous comparative studies and recommendations for its implementation are very diverse. Given the widespread use of nutritional mixtures, a thorough study of the effect of nutritional support on the dynamics of hematological and biochemical parameters in this pathology is required.
