Nutritional status of the patients is continuous concern in medical and surgical specialities. The impact of the nutritional status of the patients on the outcomes of the surgical patients is well documented in literature. Nutritional screening from admission to hospital is very important because severe malnutrition can be life threatening, especially for the patients with poor general status health. There are multiples approaches for the feeding tube placement, endoscopic, radiological or surgical approach. The final purpose is to provide the optimal amount of calories for these patients. We describe in this guide different approaches and multiples surgical techniques but also nutritional and psychological orientation. For the patients who are unable to have an oral alimentation, the negative psychological impact must be taken into account, and later can predispose the patient to social isolation and depression. The future is open for new and improved enteral feeding liquids, materials used for the tube composition and minimally invasive placement techniques.
