So, what medications can patients with anal fissures use routinely? If an anal fissure occurs, during the early stages when the fissure is new, we can use ointments such as Dragon Pearl Ointment, Jiu Hua Ointment, Musk Hemorrhoids Ointment, and Ganthai Ointment, which are hemorrhoid ointments that remove decay and promote tissue regeneration, to facilitate the healing of the wound. After defecating, we can use traditional Chinese medicine pain relievers like Shen Soup or a potassium permanganate solution for cleansing. After cleaning, we should also use some hemorrhoid suppositories for insertion into the anus, which can be used 1-2 times daily. Additionally, oral medications should be taken to lubricate the intestines and aid bowel movements. For example, liquid paraffin, hemp seed pills, hemp seed capsules, and polyethylene glycol electrolyte powder (solution), etc., to soften the stool and improve bowel conditions. If there is severe pain during or after bowel movements due to the anal fissure, local anesthesia like ropivacaine can be used at the Changqiang acupoint for a prolonged pain relief, and long-lasting pain relievers can also be injected at the base of the fissure to relieve pain during defecation. Considering the individual differences of patients, the specific medications, dosages, and precautions should be followed. It is crucial for patients to consult a doctor before using any medications to prevent misuse of drugs.

What should I do if I have an anal fissure?

So, what should we do if we have an anal fissure? Generally, for patients with early-stage anal fissures where the fissure is still fresh and without complications such as sentinel piles, hypertrophied anal papillae, anal papillitis, anal stenosis, subcutaneous fistulae, or subcutaneous abscesses, conservative treatment under medical supervision can be pursued. First, altering the diet by increasing water intake and consuming more vegetables and fruits can improve the characteristics of the stool. Post bowel movement, traditional Chinese herbal remedies for pain relief, such as Shen Tang, or sitz baths using potassium permanganate solution can be used. Locally, applications like Longzhu Ointment or Jiuhua Ointment may be applied. If constipation is present, stool softeners should be used to aid bowel movements. In the chronic stage, if symptoms are only accompanied by internal sphincter spasm and no other complications such as sentinel piles or hypertrophied anal papillae, in addition to the general treatments mentioned above, anal dilation can be considered. If dilation is ineffective, then surgical treatment should be considered at this time. For patients with chronic anal fissures who also have symptoms like sentinel piles, hypertrophied anal papillae, anal stenosis, or for those who have had prolonged ineffective treatment of initial anal fissures, it is advisable to seek surgical treatment at a hospital.

Anal fissure bleeding symptoms

The most common clinical symptoms of anal fissure, apart from the intense tearing pain in the anal area, include bleeding during bowel movements. The bleeding from anal fissures is typically bright red, and the amount of blood can increase with the severity of the condition due to repeated stretching of the fissure. Particularly during acute episodes of anal fissures or after defecation, bleeding from the local fissure can be more significant. Patients with bleeding anal fissures generally have a history of dry stools, so the first step in treating anal fissure bleeding is to lubricate the stool. Additionally, topical medications should be applied to the bleeding fissure to promote healing, and hemorrhoid creams with hemostatic properties can be used locally to help stop the bleeding. (Please use medications under the guidance of a professional physician, and do not self-medicate.)

What should I do if anal fissures keep recurring?

Repeated episodes of anal fissure generally result in the formation of chronic anal fissures. The fissure in chronic anal fissures mainly presents as an ulcer surface, and because the fissure is enclosed within the local sphincter muscles, drainage is poor, thus reducing the likelihood of healing. When patients with anal fissures suffer from long-term recurrent episodes, they also experience spasms of the local anal sphincter and tightening of the anal canal, which can lead to difficulties in bowel movements and dry stools in the anal region. When the spasm of the local anal sphincter worsens, the pain may cause patients to be afraid of defecating voluntarily, thereby creating a vicious cycle of recurrent episodes. The best treatment for recurrent chronic anal fissures is surgical intervention.

What is the best treatment for anal fissures?

How should an anal fissure be treated? It can be addressed from several aspects. First, let's talk about general treatment. What is the principle of our treatment? It is to relieve pain after bowel movements and gradually promote the healing of the fissure. However, the first step is to relieve the spasm of the sphincter, then facilitate bowel movements to interrupt the vicious cycle. But what specific measures are there? One is to take a sitz bath with traditional Chinese medicine for pain relief, such as "Shen Soup," and a 1:5000 potassium permanganate solution after defecation, maintaining local cleanliness. Then, by orally taking some laxatives or paraffin oil, feces can be softened and lubricated. Alternatively, by increasing water intake and eating more fiber-rich foods, constipation can be corrected to keep the bowels clear. In more severe cases, such as those with sphincter spasms, we can perform anal dilation under local anesthesia. By dilating the anus, the spasm of the sphincter can be relieved, and the healing of the fissure can also be promoted. However, this method has a relatively high recurrence rate, and there may also be complications such as severe bleeding, perianal abscess, and fecal incontinence. Anal dilation should be treated by a doctor, and patients should not blindly use it themselves. Of course, there is also surgical treatment. Once an anal fissure has reached a certain degree, generally a chronic anal fissure, many patients need to undergo surgical treatment. Naturally, there are several surgical methods available. We choose different surgical methods according to the condition and severity of the anal fissure. For example, if the patient has an anal fissure that presents with sentinel piles and hypertrophic anal papillae, but there is no anal stricture or internal sphincter spasm, a simple excision of the fissure can be performed. This involves removing the pathological tissue of the fissure, excising the infective anal sinus along with the hypertrophic anal papillae and sentinel piles, allowing the fissure wound to drain openly. However, if there is associated anal stricture, or there is an internal sphincter spasm, we also need to perform an internal sphincterotomy.

Can diarrhea cause anal fissures?

Diarrhea may cause anal fissures. An anal fissure refers to a full-thickness vertical tear in the skin of the anal canal below the dentate line, forming an ischemic ulcer. It is commonly found in young and middle-aged adults, and the exact mechanism of its development is not very clear. It is mainly related to local muscle spasms and infection following injury. The main symptoms include severe, sharp pain during and after bowel movements, along with occasional light, bright red bleeding. There may also be constipation and anal discharge. If the skin of the anal canal is chronically irritated by prolonged diarrhea, causing skin damage, it is very likely to lead to an anal fissure.
