What is a seton procedure for anal fistula?

In daily life, some people suffer from anal fistula, a condition in proctology that significantly affects their quality of life. Anal fistula can be treated with a procedure called seton placement surgery. But what exactly is anal fistula seton surgery?

What Is Anal Fistula Seton Surgery?

Seton placement is a surgical method used to treat anal fistulas, primarily indicated for high-position anal fistulas. Currently, it is the main treatment approach for high anal fistulas both domestically and internationally. The technique involves slowly cutting through the fistula tract using a seton thread, which simultaneously induces inflammatory adhesion at the residual ends, preventing excessive muscle contraction and preserving the normal anatomical structure of the anus. This effectively protects anal function.

Anal fistula is a common disease in proctology, often forming after an anal abscess ruptures or following incision and drainage of an abscess. It is generally classified as low-position or high-position. Low-position fistulas can typically be managed with catheter placement into the fistula tract, allowing for easy dressing changes postoperatively, with healing usually occurring within about one week. High-position fistulas require either a loose seton or a cutting seton, depending on the type and location of the fistula. A loose seton may be removed several days later, while a cutting seton needs to be tightened regularly and typically takes around two weeks to fully cut through the sphincter muscle. For complex anal fistulas, accurately identifying the internal opening is crucial to avoid improper management that could lead to recurrence.

In daily life, it's important to pay attention to any discomfort or unusual symptoms. If any health issues arise, seek timely medical evaluation and treatment. We hope this information has been helpful. Wishing you good health and happiness!
