An anal fissure is a small ulcer formed by the full-thickness splitting of the skin of the anal canal below the dentate line. A characteristic of bleeding due to an anal fissure is that it generally occurs along with periodic, tearing-like pain. Thus, bleeding and pain are the main clinical manifestations of an anal fissure. During defecation, the damaged surface can lead to bleeding from the fissure, usually with a small amount of blood. The stool may have streaks of blood, or there might be a few drops of fresh blood after defecation, or a slight smearing of fresh blood on toilet paper during wiping.

What is an anal fissure?

What is an anal fissure? In clinical practice, we often encounter patients asking this question. An anal fissure is a crack in the skin around the anal canal; simply put, it is a split in the skin at the anus. The direction of the split aligns with the direction of the anal skin's folds. Of course, not all cracks in the anal skin are called anal fissures. It is only considered an anal fissure if there is a full-thickness split in the skin at the anus. If it is a superficial skin split, it is referred to as an anal skin laceration or fissuring, such as those caused by certain anal itching diseases, which are in fact fissures in the anal skin. Anal fissures commonly occur at the “anterior and posterior midline” of the anus, which is similar to the directions of 6 o'clock and 12 o'clock as described on a clock face. Doctors often describe these as positions at 6 o'clock and 12 o'clock.

How to treat hemorrhoids, bloody stool, and anal fissures?

Hemorrhoids and anal fissures are two different conditions. Generally, the early treatment for anal fissures is similar to that for early hemorrhoids, which is conservative treatment. This includes ensuring smooth bowel movements, preventing constipation, avoiding dry stools, preventing prolonged bowel movements, and avoiding sitting still for long periods. If the amount of bleeding is small, conservative treatment as mentioned above, along with the application of local medication around the anus, can control the symptoms. Regularly consume vegetables and dietary fiber. If there is severe bleeding from hemorrhoids or severe pain due to a large fissure in anal fissures, relevant examinations should be conducted. After ruling out other conditions, surgery may be necessary.

How to examine anal fissures in women

If a woman suspects symptoms of an anal fissure, it is recommended to directly perform a digital rectal examination rather than an anoscopy, to avoid worsening the condition by potentially tearing local fissures with the anoscope. Typically, an anal fissure presents with severe local pain in the anus, bleeding during bowel movements, and accompanying hard stools. Therefore, the initial treatment should focus on softening the stool, for which one can take oral hemp seed oil capsules to facilitate bowel movements. Additionally, applying Recovery New liquid as a hot compress on the local fissures can help alleviate symptoms and promote healing. If there is anal constriction, anal dilation therapy might be chosen, or treatment may involve a lateral internal sphincterotomy. (Please use the above medications under the guidance of a physician, and do not use them indiscriminately on your own.)

What should be paid attention to for anal fissures usually?

Patients with anal fissures primarily develop the condition due to a history of dry stools or straining during early bowel movements. Therefore, it is important for patients to ensure smooth bowel movements and avoid excessive dryness of stools. Diet adjustments should include consuming more bland vegetables and fruits, and avoiding spicy foods such as chili peppers, seafood, and mutton, which are irritants. Additionally, ensuring adequate daily water intake is crucial to prevent dryness in the intestinal feces. Besides dietary and bowel adjustments, patients with anal fissures should actively seek medical treatment during acute episodes to prevent the recurrence of early fissures and the formation of chronic fissures. Early-stage fissures may be treated with topical medications to alleviate symptoms, while chronic fissures may require surgical intervention. (Medication should be administered under the guidance of a doctor.)
