Stenosis after tracheotomy can be treated by endoscopy with balloon dilatation, stent placement or tracheotomy transection.
1. Balloon dilatation: According to the endoscopic investigation of the location of the stenosis and the diameter of the stenosis, a balloon is inserted to dilate the catheter to a suitable position to achieve the dilatation effect.
2. Stent placement: according to the gastroscope to explore the tissue around the stenosis, measure the diameter of the stenosis and the distance from the hilar line, place the stent under the guidance of the guidewire, and observe and adjust the position of the stent under the X-ray to achieve the dilatation effect.
3. Transection of trachea: Silicone, stainless steel mesh or own tissue can be used to rebuild the trachea after transection of the stenotic part of the trachea. However, this method is the most harmful to the body and has poor therapeutic effect, so it is less used at present.
And patients with different physical conditions, different stages of the disease, treatment methods are also different, so under the guidance of the doctor for standardized treatment.
