Hanging thread of anal fistula

Anal fistula, one of the three common diseases of anorectal diseases, is a fibrotic fistula caused by perianal abscess, which is gradually formed by rupture of abscess and discharge of pus. Perianal abscess is the initial stage of the disease. The incidence of anal fistula is high, and it is common in young men, but it can also occur in other age groups and women. How should patients treat anal fistula? At present, the thread hanging method is often used in clinic.

Matters needing attention after anal fistula thread-drawing are particularly important, because besides surgery, dressing change and nursing after anal fistula thread-drawing are also very important for the treatment and postoperative recovery of anal fistula. Therefore, patients with anal fistula must actively cooperate with doctors for treatment, and at the same time pay enough attention to postoperative care of anal fistula, especially self-care after discharge.

Is it good to treat anal fistula by thread-hanging method?

Although thread-drawing therapy is widely used in clinic because of its convenient operation, low cost and no need for other equipment, the disadvantages of thread-drawing therapy recognized by all anorectal clinicians are also very prominent:

① It is difficult to find the inner opening: whether the inner opening can be found correctly is the key to the success or failure of hanging the line. Doctors often encounter the closure of the internal orifice when exploring for the internal orifice, that is, false healing or unobstructed pipeline, and it is difficult to find the correct internal orifice as a result.

② Wound adhesion and poor drainage: After thread hanging, the patient's anus is always contracting due to pain, so that the wounds outside the anus can't be completely released, which often makes the opened wounds quickly adhere together, resulting in poor drainage of the external orifice and easy recurrence of fistula.

③ The hanging thread is not easy to fall off: The hanging thread therapy uses the elastic retraction force of the rubber band to open the fistula, so the hanging thread usually falls off naturally in about 10 ~ 15 days. But in clinical practice, people who have hung up for more than a month will encounter it, which will only increase the pain of patients.
