As an organ of the digestive system, the stomach has the task of accepting, preparing and processing food for further digestion. Its basic functions are most often impaired when a disease occurs. One of the most common cancers in the world with high mortality is stomach cancer. It is a multifactorial disease resulting from a complex interaction between host factors, environmental factors and H. pylori infection. Epidemiological studies have shown differences with regard to the anatomical localization of the tumor as well as the histological type of cancer. Gastric cancer is more often located in the antrum and the lower third of the body of the stomach, and less often in the upper two thirds, especially in the cardia. It is more common on a small curve than on a large one. The initial symptoms are non-specific and mostly appear in the later stages of the disease. The incidence varies greatly and increases with the age of the patient. The diagnosis is most often established by endoscopy with systematic biopsies of suspicious lesions. Today, several treatment methods are available: resection, chemotherapy, radiotherapy or a combination of the aforementioned methods, and the choice depends on the size, location and extension of the tumor, that is, on the stage of the disease and on the general condition of the patient. The surgical method of treatment can be curative or palliative. The prognosis for the outcome of the disease is very poor. Enhanced Recovery After Surgery (ERAS) protocols are a multidisciplinary, evidence-based patient care system that has demonstrated exceptional effectiveness in reducing surgical complications, shortening the length of hospital stay, reducing physical and psychological trauma for patients, all with the goal of quickly achieving functional recovery. recovery. Patient health care is focused on pre-, peri- and post-operative care. The nurse's role is extremely important in patient nutrition, because enteral nutrition is the first choice, either through commercial oral preparations or through a nasojejunal feeding tube. The primary factor complicating postoperative enteral feeding is food intolerance. Patients after gastrectomy are exposed to the risk of malnutrition, and poor nutritional status negatively affects the clinical outcomes of patients, and the nurse's role in nutrition education is also important..
