If diagnosed with an anal fistula, one should not forego treatment indefinitely, as an anal fistula is a localized infectious disease of the anal region. Without active treatment, the infection may further spread, increase the number of fistula branches, and potentially induce a high, complex anal fistula. There is also a risk that the fistula and the infection might penetrate the local anal sphincter, reaching the ischioanal fossa and causing other infectious diseases. The primary treatment method for anal fistulas is surgical, mainly involving fistulotomy with seton placement, which thoroughly removes the local infection, allowing the anal fistula to heal. Neglecting active treatment could worsen the condition or increase the difficulty of future surgeries.
