If there are concurrent hemorrhoids and anal fistulas, then the clinical manifestations primarily involve the combined symptoms of both conditions. The clinical manifestations of hemorrhoids mainly include recurrent prolapse of local swellings at the anus along with defecation bleeding or pain. As for anal fistulas, they primarily present with local infectious symptoms at the anus because anal fistulas have distinct external and internal openings. During acute episodes, there typically is intermittent discharge of pus from the external opening along with accompanying stabbing pain. If the patient also has hemorrhoids or an exposed anal fissure, it is recommended to proceed with surgical treatment as soon as possible. The only treatment method for anal fistulas is surgery. During the surgery, while excising the wall of the anal fistula tract, mixed hemorrhoids can also be removed simultaneously, achieving the purpose of complete cure.

Can an anal fistula be left untreated for a lifetime?

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.

Is the probability of anal fistula turning into cancer high?

An anal fistula, formed due to an anal gland infection, carries a higher risk of malignant transformation if the infection and inflammation are recurrent and persistent, particularly over a long period exceeding five years. Therefore, it is strongly recommended that anal fistulas exceeding five years should be given sufficient attention and surgical treatment should be pursued promptly to prevent malignancy.

Best treatment method for anal fistula abscess

The best treatment method for anal fistula and perianal abscess is surgical treatment, which is also the only curative method. Conservative treatment using drugs alone can only alleviate local inflammatory symptoms and cannot achieve complete cure. The main surgical method is the cutting and threading technique. This involves threading and ligating the infected area and the sphincter muscle. Through the slow cutting and drainage action of the ligature, the infection focus is removed while protecting the anal sphincter. Postoperatively, it is also important to pay attention to disinfecting and draining the local wound, ensuring proper dressing changes, and preventing poor drainage that could lead to infection or recurrence. It is advised that patients avoid spicy and irritating foods for the first six months after surgery.

Does an anal fistula hurt?

Anal fistula mainly refers to the presence of a noticeable fistula in the tissue under the perianal skin, which connects the inner opening in the anal canal and the outer opening around the anus. Usually, the anal fistula does not cause significant pain when it is not in acute flare-up. However, if the anal fistula enters an acute episode, there may be pain due to inflammation at the local external opening of the anus, and possibly an increase in purulent discharge, which can irritate the skin around the external opening, causing stinging pain and itching. To prevent recurrent episodes of anal fistula and further aggravation of the condition, it is advised to seek surgery as soon as the fistula is detected.

How to reduce swelling when an anal fistula flares up?

An anal fistula flare-up can cause perianal swelling, pain, and discharge of pus and blood. For an anal fistula flare-up, initial conservative treatment with medications is an option, such as sitting baths using anal cleansing agents or potassium permanganate solutions after defecation. The sitting bath should last between five to ten minutes to help reduce swelling and relieve pain. After the bath, topical application of mupirocin ointment or other anti-inflammatory ointments like Golden Ointment may also be used to reduce swelling and inflammation. For severe infections, intravenous or oral antibiotics may be prescribed to reduce inflammation. However, clinically, it is recommended to opt for surgical removal of the anal fistula as early as possible. Early removal of the internal opening and the fistula tract is necessary for a complete cure of the anal fistula. If an anal fistula repeatedly flares up, it can easily lead to the formation of more fistula branches, forming complex anal fistulas, increasing the difficulty of later surgeries and enlarging the wound surface post-operation.
