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.

How long does it take for the rubber band of an anal fistula to fall off?

For high anal fistulas, we opt for the seton therapy, where we typically use rubber bands as the thread. For the rubber bands used in seton therapy, we believe it is best if they fall off around ten days. Therefore, for the anal fistula rubber bands, we think it is ideal if they fall off in about two weeks at the latest. If they have not fallen off after about two weeks, we may consider further interventions such as cutting the thread or directly cutting the sphincter muscle.

How long does it take for an anal fistula to form?

An anal fistula is a tract left after an anal abscess bursts spontaneously or is surgically drained, generally consisting of a primary internal opening, a fistula tract, and a secondary external opening. Thus, an anal fistula and an anal abscess represent two stages of the same disease: initially, there is an anal abscess, and then, after the pus from the abscess is drained, an anal fistula forms. Typically, the transformation from an anal abscess to an anal fistula takes about two to three months, meaning that an anal fistula can form about three months after the abscess bursts.

Can anal fistula be completely cured?

Anal fistulas rarely heal naturally, and surgery is the only treatment method to achieve healing. The reasons are as follows: Aside from an external opening on the skin around the anus, an anal fistula also has a primary infectious internal opening in the anal crypt. The two openings are interconnected, allowing bacteria and intestinal contents to enter the fistula tract through the internal opening, leading to recurrent infections. Persistent inflammation often prevents pus from draining through the external opening. There are complex relationships between the fistula and the sphincter muscles, and the frequent contraction and relaxation of the sphincter muscles can compress the tract, making it easy for pus to remain and cause infection. Therefore, surgery is necessary to completely cure an anal fistula.

What should I do about an anal fistula?

Anal fistula is a disease that occurs when repeated infections in the anal crypts extend to the surface of the skin around the anus. Once formed, there are typical fistula tracts with both internal and external openings. Simple anti-inflammatory drug treatments can only relieve the symptoms of inflammation during the acute phase of an anal fistula. For the fistula tracts themselves, these treatments do not completely cure the condition. It is recommended that patients with an anal fistula undergo a fistulotomy as soon as they are diagnosed. Through surgery, the fistula tract and its walls can be completely excised, completely removing the local lesion, thereby further accelerating the regrowth of fresh granulation tissue locally.

What should be paid attention to for anal fistula?

Patients with anal fistula, as there is an external opening in the anal region and intermittent thick secretion from this opening, should first ensure to keep the perianal area clean. It is recommended to change underwear daily and to cleanse the area after bowel movements with saline or hemorrhoid wash, and to conduct fumigation and hot compresses around the perianal area and the external opening to prevent irritation and even sharp pain caused by residual feces and secretions. Furthermore, during acute episodes of anal fistula, mupirocin ointment can be applied around the external opening for anti-inflammatory treatment. The definitive surgery for anal fistula primarily involves fistulotomy with seton placement. Without surgery, an anal fistula cannot be completely cured and may lead to worsened conditions such as thickening of the fistula wall or increased branching of the fistula channels.
