Gastric surgery often requires a gastric tube and a period of fasting from food and water. How to arrange the diet after gastric surgery so that the patient can recover as soon as possible? The duration of gastric tube placement in our hospital is usually 4 to 7 days for partial gastrectomy and 6 to 9 days for total gastrectomy patients. During this period of time, patients are not allowed to eat anything by mouth or drink water. So what is the nutrition supply during this period? Intravenous fluids or a jejunostomy tube are used to supply nutrients. Nutritional supply before removal of gastric tube: The nutrition of patients with gastric tube is mainly done by medical staff, with the cooperation of patients and family members. The nutrient solution administered intravenously is usually glucose, saline, amino acids, fat milk, vitamins and trace elements. It may also be a combination of these ingredients, such as “carven” (a large bag of milk-like liquid). The infusion through the jejunostomy tube may be sugar, saline, Risperdal, Pepto-Bismol, and other nutritional drugs. Milk, soy milk, vegetable soup, broth, fish soup and juice can also be used instead. If the doctor asks the family to provide these substitutes during this time, the family must provide fresh, not spoiled, fully boiled soups. No chili peppers or large spices should be added. Soups require less salt, light, and finely gauze filtered without scum. Soup types should be varied. Nutritional supply after removal of gastric tube: The formula is mostly implemented by family members or patients themselves under the guidance of medical staff. Most of the total gastrectomy patients after the removal of gastric tube, although they can eat through the mouth, but the amount of food the patient eats is limited and cannot ensure sufficient nutrition, so the jejunostomy nutrition tube often needs to be maintained for a period of time. During this time, a two-pronged approach can be used, with nutrition partially supplied through the mouth and insufficient nutrition infused through the jejunostomy tube. Other patients, who have already been discharged from the hospital, can be fully nourished with a transoral diet, and the purpose of maintaining a jejunostomy tube is to provide coverage for the chemotherapy that will follow. Patients undergoing chemotherapy often do not have poor appetite, nausea, or vomiting that prevents them from eating, and a jejunostomy nutrition tube can ensure adequate nutrition to complete chemotherapy. Patients and family members who go home with jejunostomy nutrition tubes must learn the care of the jejunostomy tube and master the method of implementing nutrition with the jejunostomy tube so that the patient can implement jejunostomy nutrition at home after discharge from the hospital. Since the nutrition solution in pharmaceutical or commercial words is more expensive, for patients with good recovery of intestinal function, the infusion of nutrition solution is mostly made of ordinary soups made by themselves. These broth, fish soup, vegetable soup, milk, juice, soy milk is the same as we usually drink. Soups must be clean, fresh, dregs-free, light, and varied. Pay attention to the consistency, temperature, and speed. Soup should not be too thick, too salty, too sweet, and the temperature should be 37 to 42 degrees. Patients with good gastrointestinal function can use the intermittent push method, using a large syringe to pump prepared soup, 100 to 300 ml each time, slowly and uniformly over 10 to 20 minutes, which can be repeated in about 3 hours depending on the patient’s tolerance. The tube should be flushed with water before and after each infusion to prevent blockage of the tube. Of course, nutritional drugs from pharmacies or commercial nutrients, such as Nensin, can be used, but they are not cost-effective for patients with good gastrointestinal function. When the patient’s nutritional needs can be met by oral feeding, stop feeding through the jejunostomy tube, and consider removing the jejunostomy tube after a week or so of observation. Most of the patients after partial gastrectomy do not have a nutrition tube placed, and the transition from intravenous nutrition to transoral diet is direct. The principles of transoral diet are: 1. chew slowly, eat less and eat more. Patients discharged from the hospital with partial gastrectomy generally eat 6 meals per day, and can generally resume their pre-surgical diet 3 months after surgery. Patients with total gastrectomy generally eat 6 to 8 meals a day when they are discharged from the hospital, and they can gradually resume their pre-surgical diet one year after discharge. 2, meat and vegetables, comprehensive nutrition; patients after gastric surgery often lead to a lack of certain nutrients vitamin trace elements, which can lead to anemia, so we should pay more attention to comprehensive nutrition, balanced nutrition. 3.From thin to thick, from less to more gradually; generally eat a liquid diet for 3 days after the removal of gastric tube, then eat a semi-liquid diet for 3 days, and then over to the general diet. 4.Eating in sitting position and proper exercise. Patients often have different degrees of gastroesophageal reflux after gastric surgery, avoid eating in a reclining position, and stroll for more than 30 minutes after eating before going to bed, which can reduce the occurrence of reflux. 5, avoid spicy, too hot and cold, dry, hard, rough, thorny, angular food to prevent damage to the digestive tract. Especially in patients with total gastrectomy, food passes through the esophagus without the grinding of the stomach, acid corrosion directly into the small intestine, which is much weaker than the stomach, and if the food is not carefully chewed, thorns or angles, it is likely to damage the small intestine and even cause perforation.
