Fistulas can be divided into congenital and acquired fistulas, acquired fistulas are common, such as intra-abdominal fistulas, anal fistulas, etc. Congenital fistulas, such as thyroglossal fistulas, are treated differently in different cases and generally have better results after treatment. 1. The application of non-surgical treatment methods can not be cured, surgical excision is preferred, and the entire fistula can be removed with the help of probe guidance during surgery. When the fistula cannot be identified between the supraglottis and the lingual blind foramen, a columnar resection of the lingual muscle can be done. Acute infection should be controlled inflammation before surgery; 2. Intra-abdominal fistula: such as intestinal fistula, biliary fistula, etc., is caused by surgery, trauma, abdominal infection, etc., mainly occurs after abdominal surgery, should be further selected for dissection and exploration for sinus resection, after surgery can be given negative pressure suction to remove intra-abdominal secretions, pay attention to maintain water and electrolyte balance, appropriate application of antibiotics anti-infection, generally better treatment; 3. The first thing you need to do is to take a look at the actual fistula, and then you can use the fistula as a way to get it out of the way.
