How to distinguish between anal fissures and hemorrhoids

To distinguish between anal fissures and hemorrhoids, one can first differentiate based on symptoms. Anal fissures primarily cause pain during defecation and minor bleeding, with the pain typically lasting from 20 minutes to half an hour. Patients often have hard stools or constipation. In contrast, hemorrhoids primarily lead to intermittent painless rectal bleeding. The blood is bright red and usually in greater volume, often appearing in a spraying or dripping pattern after defecation. Some patients may also experience prolapsed hemorrhoids, often accompanied by a sensation of heaviness and foreign body in the anus. Further, through a digital rectal examination, an anal fissure can be identified by a palpable ulcer or crack at the posterior or anterior midline of the anus. Hemorrhoids, being soft venous clusters, can also be differentiated through this examination.

The differences between stages one, two, and three of anal fissures.

In clinical practice, anal fissures are not categorized into stages one, two, or three; they are primarily classified as either acute or chronic anal fissures. Acute anal fissures, which occur in the early stages of the condition, are characterized by pain during defecation and minor bleeding. For such cases, the pain usually doesn’t last long, and conservative treatment with medication can be chosen. Topical applications such as dragon's pearl ointment or nitroglycerin ointment are generally used. It is also important to keep the anal region dry and clean, perhaps by using anal washes for sitz baths, while ensuring that the stool is soft to maintain smooth bowel movements. Chronic anal fissures, on the other hand, are mainly due to the development of scars on the ulcer surface. This condition involves prolonged pain and may include some narrowing of the anus. In such cases, surgical excision of the fissure may be necessary. Post-surgery treatment may include changing dressings with medications like red oil gauze strips, golden ointment, and anal washes. (Under the guidance of a doctor for medication use)

How many days can an anal fissure heal?

Mild anal fissures or those with shallow cracks can generally heal within about a week through local heat application or by applying hemorrhoid cream. However, there is another type of anal fissure known as chronic anal fissure. Chronic anal fissures primarily involve ulcer-like infectious changes at the local site, hence, they cannot heal on their own and can only be alleviated by lubricating the stools and applying hemorrhoid cream locally. In some cases, conservative treatment might not be significantly effective for chronic anal fissures. If surgery is performed, the recovery time is approximately 20 days. It is recommended that patients with chronic anal fissures undergo surgical treatment with endoscopic loosening.

Are anal fissures and hemorrhoids the same thing?

Hemorrhoids and anal fissures are common clinical conditions, but their symptoms are completely different. Generally, they both share a common symptom, which is the presence of rectal bleeding, and this bleeding is usually bright red blood. The difference between anal fissures and hemorrhoids is that anal fissures primarily cause pain, while hemorrhoids primarily cause bleeding. Hemorrhoids only cause severe pain when external hemorrhoids become inflamed and swollen, while anal fissures often involve enlargement of the anal papillae. Hemorrhoids do not involve enlargement of the anal papillae, and while anal fissures can involve skin tears around the anal canal, hemorrhoids do not. During a digital rectal exam, this can be diagnosed; hemorrhoids are caused by poor local venous circulation, leading to venous congestion and the formation of vascular bulges. Depending on their location, they are divided into internal and external hemorrhoids. Anal fissures are skin tears located on the more lateral parts of the anus, and during defecation, the tear worsens, bleeding and causing severe pain, whereas hemorrhoids usually do not cause severe pain.

What causes anal fissures?

Anal fissure is a series of clinical symptoms such as pain or rectal bleeding that occur due to the formation of a crack in the local sphincter muscle of the anus. The main reason for the occurrence of anal fissures is due to poor defecation habits in the early stages of the patient, or excessively dry stools, and excessive force during defecation, causing the local sphincter to burst, resulting in the fissure opening pain or bleeding. To treat anal fissures, it is first necessary to soften the patient's stools and adjust defecation habits. If the patient's diet is poor, it is recommended to maintain a light, easily digestible diet long-term. For those with dry stools, appropriate oral medications to lubricate the intestines and facilitate bowel movements can be used, or sesame oil can be applied around the anus before each defecation to lubricate the stool. If recurrent episodes of anal fissures occur, surgical treatment can also be directly performed. (Medication use should be under the guidance of a doctor.)

What should I do about anal bleeding and anal fissures?

If a fissure is visible to the naked eye at the anal sphincter during a digital rectal examination, it is primarily considered an anal fissure. Anal fissures generally cause severe local pain and bleeding from the fissure. The fissure is primarily due to the local crack being stretched or opened, causing bleeding from small blood vessels, and the blood from the fissure is usually bright red. To treat bleeding from an anal fissure, it is first necessary to soften the stool, as the occurrence of an anal fissure is mainly related to dry stools and difficulty defecating. Once the stool is lubricated, it can reduce the need to exert excessive force during defecation, lowering the possibility of stretching the local fissure. Topical application of hemorrhoid cream at the fissure, or combined with oral medications that cool the blood and stop bleeding, may be used. If there is repeated bleeding from an anal fissure, surgical treatment is also recommended. (Please use medications under the guidance of a professional physician, and do not self-medicate.)

What is the best treatment for a minor anal fissure?

Minor anal fissures, which are early-stage fissures, mainly manifest as pain during defecation and minor bleeding, but the pain does not last long and is primarily associated with defecation. For minor fissures, it is generally recommended to choose conservative treatment with medications and dietary regulation to ensure smooth bowel movements. Typically, after defecation, one can choose to use an anal cleansing solution or a potassium permanganate solution for a sitz bath. After the sitz bath, apply Dragon Ball ointment or nitroglycerin ointment locally to promote the healing of the ulcerated surface. At the same time, in terms of diet, one should drink more water and consume foods rich in dietary fiber to maintain smooth bowel movements as much as possible, avoiding dry and hard stools, which also helps in the healing of minor anal fissures. Additionally, patients should pay attention to keeping the anal area dry and clean, avoid irritating the wound, and prevent infection that could exacerbate the condition.

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 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.

What should I do about rectal bleeding from an anal fissure?

Firstly, if rectal bleeding occurs before a doctor's diagnosis, it is imperative to seek medical attention promptly to rule out other conditions. The cause of the bleeding could be from a site above the anus or other diseases related to the anus, and it might not necessarily be an anal fissure. If diagnosed with an anal fissure, treatment generally involves the local application of ointment. It is important to avoid conditions in daily life that could lead to constipation or diarrhea, as these can irritate the mucous membrane of the anus and exacerbate the symptoms of an anal fissure. Dietarily, it is beneficial to eat more vegetables, fruits, and foods high in rough fiber to ensure that stools are well-formed. If anal fissures recur, do not avoid seeking medical help, as this could lead to the formation of scars and contractions around the anus, causing anal stenosis, at which point surgery would be necessary.
