The survival period of patients with mid-stage esophageal cancer after surgery is related to the stage of tumor and the patient’s basic condition, which needs to be analyzed on a case-by-case basis. Esophageal cancer is a malignant tumor occurring in the epithelial tissues of esophagus, which can be treated by surgical resection if the patient is indicated for surgery, and the surrounding lymph nodes should be cleared and pathological examination should be performed during surgery. In general, patients with mid-stage esophageal cancer can survive for a long time after surgery, and if there is no distant metastasis of lymph nodes and mediastinal lymph node metastasis, the five-year survival rate of patients can be more than 70%. At the same time, patients should also pay attention to avoid eating spicy and stimulating food after surgery to avoid stimulating the esophageal anastomosis and stomach and causing functional disorders. In addition, since esophageal cancer surgery will remove the esophagus of the lesion, the stomach is often used to replace the function of esophagus after surgery, which will bring part of the stomach up to the thoracic cavity and lead to the change of normal anatomical structure, so patients should not eat too much after surgery to avoid the compression of the lungs in the thoracic cavity and cause breathing difficulties.
