A little choking after esophageal cancer surgery is considered to be caused by normal postoperative condition, narrowing of surgical anastomosis and postoperative scar proliferation. Esophageal cancer is a kind of malignant tumor occurring in the epithelial cells of esophagus. When patients undergo surgery for esophageal cancer, the function of esophagus usually needs about 7 days after surgery to recover gradually. At this time, patients need to eat mainly liquid food, if they eat normal food, it may cause blockage of esophagus and a little choking after esophageal cancer surgery. At present, the commonly used clinical surgery for esophageal cancer is partial esophagectomy. After the patient’s esophageal lesion is removed, the doctor needs to suture the remaining esophagus to maintain the normal function of the patient’s esophagus. If the anastomosis of the esophagus is narrowed after the surgery, food cannot pass through the esophagus smoothly after eating, and thus a bit of choking occurs. Meanwhile, if the scar of esophagus is hyperplasia after surgery, it will also cause narrowing of esophagus and the symptom of choking after esophageal cancer surgery. It is recommended that patients with choking after esophageal cancer surgery should consult doctor in time to clarify the cause of the disease. Meanwhile, if the operation time is long, patients should be alerted to the recurrence of esophageal cancer.
