Whether or not a gastric tube can be inserted in patients with esophageal varices depends on the severity of the patient’s esophageal varices. If the patient has mild esophageal varices, gastric tube can be inserted as appropriate, and the operator should be careful to use a gentle technique and should not operate roughly, so as to avoid causing injury to the patient or even endangering the patient’s life. If the patient’s esophageal varices are severe, it is better not to insert a gastric tube. Because the blood vessels of patients with severe esophageal varices are fragile, a slight carelessness in operation may cause blood vessel rupture, resulting in bleeding in the upper gastrointestinal tract of the patient, and in serious cases, it may even jeopardize the patient’s life. If a patient with severe esophageal varices needs to have a gastric tube inserted because he or she is unable to eat for a long period of time, he or she should be careful during the operation to avoid harming the patient. From the above, whether or not a gastric tube can be inserted into a patient with esophageal varices should be evaluated according to the degree of the disease and the benefits that a gastric tube can bring to the patient. If a patient has esophageal varices and needs to have a gastric tube inserted, he or she should go to the hospital to be evaluated by a doctor to see if it is possible to insert a gastric tube, and the patient should cooperate with the doctor in order to avoid serious consequences.
