The esophagus and stomach are important parts of the human digestive system and are the organs that deliver, transport and contain food. Most of the patients with esophageal and cardia cancer have to undergo total or partial resection of esophagus and stomach for the purpose of 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. Therefore, it is very important for patients with esophageal and cardia cancer to eat well after surgery, which can be roughly divided into three stages. The liquid food stage refers to 5-10 days after surgery. During this period, the patient has basically passed the surgery trauma period, and the gastrointestinal function starts to recover gradually, which is manifested as appetite and anal venting (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 starts from the second week after surgery. 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), and all foods can be eaten except those that the physician specifically emphasized not to eat at the time of discharge, and the patient can be instructed to do some appropriate physical activities to facilitate digestion and absorption. During this period, a few patients may have symptoms such as epigastric fullness and acid vomiting, and may take morpholine 20 mg (2 tablets) 3 times a day. If the symptoms are not relieved after medication, the patient may go to the hospital for consultation and treatment.
