The esophagus and stomach are important parts of the human digestive system and are the organs that deliver, transport and hold food. Most patients with esophageal cancer and cardia cancer have to undergo total or partial resection of esophagus and stomach to achieve radical treatment, and then use stomach or intestinal tube as replacement graft to reconstruct the digestive tract. The whole operation is very traumatic and often causes digestive disorders. For this reason, it is very important for patients with esophageal and cardia cancer to eat well after surgery, which can be roughly divided into four stages. Nasal feeding stage 1~5 days after surgery, the patient is just in the traumatic period of surgery, the anastomosis has not yet healed, the gastrointestinal function has not yet recovered well, and the digestive function is poor. During this period, only nasal feeding can be used. It is a very thin and specially designed nutrition tube placed through the nose directly to the jejunum to deliver nutrition. During the nasal feeding stage, the patient can be fed with mixed milk, vegetable juice, fruit juice, rice soup, etc. The injection volume can be divided into 2-3 drips from 500 ml on the first day, and then increased to 1500-2000 ml per day according to the patient’s tolerance. The temperature at the time of dripping is appropriate to approximate the body temperature. It is required that the nasal nutrition solution should contain protein, fat, carbohydrate, vitamin, salt and water in appropriate proportions as far as possible. The fluid phase refers to 5 to 10 days after surgery. During this period, the patient has basically passed the surgical trauma period, and the gastrointestinal function starts to recover gradually, manifested as appetite and anal exhaust (commonly known as farting). A small amount of plain water (3 to 5 tablespoons) can be given at first, gradually increasing to 30 to 50 ml. If there is no obvious discomfort, rice soup, egg soup, fresh milk, fish soup and various types of poultry simmered soup can be given, 100 to 200 ml each time, 5 to 7 times a day. The semi-fluid diet phase begins in the second postoperative week. During this period, all kinds of drains left in patients after surgery have been removed, and intravenous fluid infusion is gradually stopped. Except for some elderly or super-elderly patients who cannot get out of bed, most of them can walk and move around, and the amount of food is gradually increased. However, during this period, only small meals can be eaten, mainly easy-to-digest non-slag food (such as thin rice, noodles, egg custard, tofu, etc.), especially some patients with large preoperative food intake should not eat a lot to avoid causing 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 are being cared for by their own loved ones. At this time, the diet can be expanded as much as possible (except for fried and sweet foods).
