Patient's question:
5 years ago, did you also do it in your hospital in Songming?Doctor's answer:
The surgery can be performed under local infiltration anesthesia with 1% novocaine, while children can undergo it under general anesthesia. During the procedure, a probe can be used for guidance, or a blunt needle can be inserted into the fistula before surgery to inject methylene blue or methyl violet as a marker. When using this method, the amount of medication should not be excessive. After injection, gently massage and wipe off any excess dye to avoid contaminating the surgical site.
