Esophagus and stomach are important parts of human body’s digestive system, which are organs for passing, transporting and holding food. Most of the patients with esophageal cancer and cardia cancer have to undergo subtotal or partial resection of the esophagus and stomach to achieve the goal of radical treatment, and then use the stomach or intestinal tube as a substitute transplantation to rebuild the digestive tract. The whole surgical process is very traumatic and often causes digestive disorders. Therefore, it is very important for patients with esophageal cancer and cardia cancer to eat well after operation, which can be roughly divided into four stages. Nasogastric feeding stage: 1~5 days after operation, the patient is in the traumatic period of operation, the anastomosis is not yet healed, the gastrointestinal function is not well recovered, and the digestive function is poor. During this period, only nasal feeding can be taken. It is to place a very thin and special nutritional tube through the nose directly to the jejunum to deliver nutrients. Nasogastric feeding stage can be fed to the patient mixed milk, vegetable juice, fruit juice, rice soup, etc., the amount of injection can be from the first day of 500 milliliters, divided into 2~3 times, and then increased to 1500~2000 milliliters per day according to the patient’s tolerance. The temperature at the time of dripping is appropriate to approximate the body temperature. Nasogastric nutrient solution is required to contain protein, fat, carbohydrates, vitamins, salt and water in appropriate proportions as much as possible. The fluids phase refers to 5 to 10 days after surgery. During this time, the patient has basically passed the surgical trauma period, gastrointestinal function began to gradually recover, manifested as appetite, anal exhaust (commonly known as farting). A small amount of plain water (3~5 tablespoons) can be given first, gradually increasing to 30~50 ml. If there is no obvious discomfort, rice soup, egg soup, fresh milk, fish soup and various kinds of poultry simmered soups can be given, 100~200 ml each time, 5~7 meals per day. The semi-liquid diet stage starts from the second postoperative week. During this period, the patients’ postoperative drainage tubes have been removed, and intravenous fluid infusion has been gradually stopped, and most of them can walk, and their food intake has been gradually increased, except for some elderly or super-elderly patients who can’t get out of bed. But this period can only eat small meals, to easy to digest the main food without residue (such as thin rice, noodles, egg custard, tofu, etc.), especially some preoperative patients with a large amount of food should not eat a lot of food, so as not to cause gastrointestinal complications or anastomotic fistula. Normal Diet Phase This phase usually starts from the fourth week after surgery. During this time, most patients have been discharged from the hospital to rest at home and be taken care of by their own relatives. At this time, the diet can be expanded as much as possible (except for fried and sweet foods).
