Ten months ago, Mr. Li, 59 years old, developed choking sensation when eating solid food like steamed buns, which needed to be served with water, and gradually developed to choking sensation when eating rice. Mr. Li underwent gastroscopy at a local hospital and was diagnosed with upper esophageal carcinoma, biopsied as squamous carcinoma, and received radiotherapy. One month after the radiotherapy, Mr. Li started to feel obvious choking and coughing when eating liquid food, and underwent upper gastrointestinal angiography in the hospital, which showed esophageal tracheal fistula, and he underwent gastrostomy (a kind of surgical operation for patients with esophageal obstruction) half a year ago. Half a month ago, after Mr. Li was injected with nutritional fluid into the gastrostomy tube, he would experience nausea, choking and coughing, and could cough up the injected food, so he was referred to our hospital for further diagnosis and treatment. Since the onset of the disease, less than a year, Mr. Li actually lost 50 pounds. After admission, tracheoscopy was performed under general anesthesia. There was a fistula of about 1.5 cm in diameter in the posterior wall of the trachea at 6 cm from the vocal folds, and the surface was covered with a small amount of dirty moss, with secretions overflowing continuously; under direct vision of the tracheoscope, a Y-shaped tracheal laminating stent was placed, and the stent was released well. After surgery, Mr. Li’s choking symptoms were significantly reduced. Mr. Li’s choking symptoms were significantly reduced after the operation. The fistula had constant secretion overflow, and the Y-shaped stent was placed. The most effective way to seal an esophagotracheal fistula is to place an endoprosthesis. Depending on the location, size and nature of the fistula, stents of different shapes and materials can be placed. Stents can be categorized as either metallic or non-metallic. Generally, customized metal perimetallic stents can effectively seal the fistula, such as postoperative stent adverse reaction is more serious, can also choose silicone stent, prohibit the airway bare stent. After bronchoscopic or gastroscopic intervention, it can greatly reduce the patient’s symptoms and improve the quality of life.
