Benign tracheal stenosis includes various benign diseases (e.g. polyps, tuberculosis, etc.) and, increasingly in recent years, scar stenosis after tracheal intubation or tracheotomy. In some cases, because of repeated fiberoptic bronchoscopic cryotherapy or laser treatment, the milder the case is, the more complicated it is, the more extensive the lesion, the heavier the scar, the longer the stenotic segment, and the high degree of tracheal stenosis can accommodate only a very thin intubation tube, and the patient is unable to live normally with only a thin tube for breathing. In tracheotomy patients, the trachea above the stenosis can be completely filled with scar tissue, the lumen is completely closed, and the patient is unable to speak for the rest of his or her life. Since most patients with tracheal stenosis, who are treated by bronchoscopy, are in contact with a respiratory physician. Trachelectomy, in turn, is a rather difficult major surgery, so risky and difficult that most hospitals and doctors specializing in surgery and quintuplegia, do not see them. As a result, many people, even many doctors, do not know about trachelectomy surgical treatment or know that it is available but do not know where to find a surgeon. As a result, many people undergo tracheal stenting in order to solve the patient’s breathing difficulties. Unbeknownst to them, stents can indeed solve the breathing difficulty immediately after they are put in, but it is difficult for patients to live a normal life with stents. The worst thing is that no matter domestic or imported stents, no matter bare stents or coated stents, it is difficult to avoid the growth of granulation, as a result, soon the granulation grows in the lumen of the trachea and stenoses again, still needing repeated freezing or laser treatment. With endless pain, it’s hard to imagine how a teenager would get through their life if they were a teenager! An even more serious problem is that tracheal stents can cause tracheal perforation, forming tracheoesophageal fistulas and tracheal vascular fistulas. The latter can lead to a quick death. The former is worse than death. Tracheoesophageal fistulas can cause choking and coughing as soon as the patient eats or drinks, recurrent lung infections or even the formation of lung abscesses, etc., and eventually painful, safe disability, or death due to malnutrition and infection. For difficult and complex severe benign tracheal stenosis, the most effective treatment for patients who do not respond well to transbronchoscopic cryo-laser treatment is surgical resection. Of course, surgery is indeed a little more difficult. But only surgery can ultimately lead to a cure. The trachea can be removed up to half its length. But not many hospitals and doctors are able to do this. And once the trachea is removed and the anastomosis fails, it is an unacceptable disaster for both the patient and the doctor. We have invented the world’s only artificial trachea that can be healed into one with the own trachea, which gives us the ability and certainty to remove large tracheal lesions and avoid the catastrophic situation of failure to anastomose. We have performed dozens of trachelectomies, including large segment resections and artificial tracheal replacements, and have gained a lot of valuable experience, which is a boon for patients with complex and difficult tracheal stenosis. If you are a physician, please note that you should not easily place tracheal stents in patients you cannot treat and can refer patients to our hospital. If you are a patient or family member with benign tracheal stenosis, please remember to avoid tracheal stenting if possible. It should be treated surgically. In case a stent is placed, it does not matter, you can visit our hospital to see if there is still a chance of surgical treatment. In short, surgery is the only way to truly and completely solve the problem of tracheal stenosis and allow the patient to resume a normal life and work!
