Experts from Nanjing Shuguang Anorectal Hospital said: First, long-term chronic inflammatory stimulation: due to the long-term unhealed anal fistula and long-term inflammation, pus and feces are discharged from the fistula, which stimulates abnormal cell proliferation and leads to malignant lesions; Secondly, the long-term presence of bacteria in the fistula, especially Pseudomonas aeruginosa or Mycobacterium tuberculosis infection, will also lead to the canceration of anal fistula. There are also many patients with anal fistula who take a lot of drugs for a long time. These drugs often irritate the local area, cause pathological changes, and easily lead to the tendency of anal fistula to become cancerous.

Clinically, mucinous adenocarcinoma is the majority in the canceration of anal fistula, and induration, mucus secretion and pain are often precursors of canceration, which should be paid great attention to. Because anal fistula will become cancerous after a long time, it should be treated as soon as possible. In view of the recurrence of anal fistula mentioned above, the main reason is that the internal orifice is not handled well. Nanjing Shuguang Anorectal Hospital uses minimally invasive therapy to treat anal fistula, and you can rest assured in terms of technology and efficacy. Minimally invasive treatment of anal fistula, with the help of advanced probe combined with hydrogen peroxide perfusion method, accurately find all internal orifices, effectively avoid missed diagnosis and treatment. Contrary to the traditional way of picking out all fistulas, only the main focus is cut, mouth-to-mouth drainage is carried out, the internal and external orifices are decomposed, and some incisions are reserved, thus simplifying the complex. While treating diseases, the anal function is not damaged, and the surgical wound is reduced by at least two thirds, thus minimizing the harm to the body. The whole process is painless, the treatment is thorough and the recovery is fast, which greatly reduces the pain of patients.
