As the old saying goes, “man is steel”, but many patients with benign esophageal stenosis suffer from the difficulty of eating and “look forward to eating”, suffering. Esophageal dilatation is often used to solve this problem. Commonly used dilatation methods need to be carried out under local anesthesia with the assistance of rigid or fiberoptic esophagoscopy, which is painful, maintains the efficacy of a short period of time, and some of them recur in just a few days, and is also prone to bleeding, esophageal rupture and other serious and life-threatening complications, and the treatment cost is expensive, and a time requires thousands of dollars. Our center has introduced a brand-new technology from the United States to treat all kinds of benign esophageal stenosis, and has achieved breakthrough results. It is called “self-help” esophageal dilatation method because it does not require special large-scale equipment and can be performed by patients with a little training. The esophageal dilators used in this dilatation method are made of precision-processed medical polymer materials, and the doctor can choose the appropriate model for dilatation according to the patient’s degree of esophageal stenosis. No anesthesia and auxiliary therapeutic tools are needed in the dilatation process. When the dilatation is first performed, the doctor assists the patient to insert the dilatator into the esophagus from the oral cavity, and the surface of the dilatator is very smooth after it meets the saliva, so the patient can do some swallowing movements like eating noodles with the insertion of the dilatator, and leave it in place for more than 30 minutes after passing through the site where the stricture is committed. Daily single or morning and evening respectively, one to three weeks for a course of treatment. This method is simple and easy to implement, the patient after the doctor 1-3 times to assist in the expansion that can be skillfully mastered, then you can take the dilatation of the sub-home, self-expansion. “Self-help” dilatation method is characterized by certain curative effect, high safety, little pain, easy operation, low technical requirements and low treatment cost. It fully mobilizes the active participation of patients in the treatment and strengthens their confidence in overcoming the disease. It is suitable for benign esophageal stenosis caused by various reasons, such as benign and malignant esophageal tumors, cardia failure, esophageal diverticulum and other postoperative esophageal diseases, esophageal chemical burns and so on. Now our center has successfully let dozens of patients solve the problem of esophageal stenosis by themselves without any complication. It is believed that more patients with benign esophageal stenosis will benefit from this method as its use expands.
