[Assessment of nutritive status and its correction in oncological patients after operations in the hepatopancreatoduodenal zone].

Surgical interventions in the hepatopancreatoduodenal zone in cancer patients are associated with high risk of nutritional deficiency in the postoperative period. This feature is due to both the volume of the operation itself (pancreatoduodenectomy), and the predominance of catabolic processes in the early postoperative period. In this regard, the monitoring of the main indicators of carbohydrate, protein and fat metabolism in the early postoperative period becomes fundamental for choosing the correct tactics of nutritional support for this patients.
