After gastrostomy, each time you can inject fluid food in about 250 mg, the specific need to judge with the patient’s personal physical condition. Gastrostomy is to put the tube into the stomach cavity through the abdominal wall, fix the tube in the abdominal wall, and input the nutrient liquid into the cavity through the tube outside the abdominal wall to ensure the nutrition supply of the human body, which is generally used for the treatment of patients with advanced esophageal cancer. After the operation, the patients are not allowed to eat, and they can break the food into pieces, and then beat it in through fistula tube, and they generally need to inject about 250 mg of fluid food each time, and eat small amount of meals more than once. After the operation, we should avoid the infection of the wound, and when injecting food with fistula tube, the injection speed should not be too fast, and the concentration of food should not be too big to avoid causing intestinal spasm of the patient.
