An anal fissure is a small tear in the skin around the anus. It can be so uncomfortable that it directly affects daily life because this tear can cause pain during bowel movements, like a glass cut. Although it may seem like a simple wound, it actually harbors many issues related to the body.
What is Anal Fissure?
An anal fissure refers to a small but very painful tear that occurs in the skin around the anus, indicating a crack in the rectum. It usually occurs as a result of straining during bowel movements. Despite being on the surface of the skin, it can cause pain severe enough to significantly affect daily life due to its location in a nerve-rich area. Chronic anal fissure is a term used for cracks that have existed for more than eight weeks and do not heal spontaneously.
What are the Symptoms of Anal Fissure?
The most common symptom of a fissure in the rectum is a sharp pain felt during toilet use, akin to a glass cut. This pain is so intense that a person may want to postpone the next bowel movement as much as possible, but this avoidance leads to constipation, worsening the problem. In cases of persistent pain and bleeding, a diagnosis of chronic anal fissure should be considered. Common symptoms of anal fissure include:
- Pain: A sudden sharp pain is felt around the anus during bowel movements, especially when passing hard or straining stools. This pain is often described as sharp, like a knife. Even after the toilet visit, the pain may persist. A throbbing and burning sensation may continue in the area for a while.
- Bleeding: Bright red blood noticed on toilet paper after using the toilet is often confused with hemorrhoids. However, in anal fissures, the bleeding is usually superficial but still needs to be taken seriously. The presence of bright red blood after using the toilet is frequently evaluated as a sign of anal fissure bleeding.
- Skin sensitivity and irritation: Over time, a feeling of discomfort develops in the skin around the anus. The area may feel irritated, burning, or itching even when sitting, walking, or coming into contact with underwear. These symptoms may start off mild but become noticeable over time.
- Fear of bowel movements: The intensity of the pain leads a person to involuntarily postpone bowel movements. This situation triggers constipation, which causes the fissure to deepen and become chronic.
How Does Anal Fissure Occur?
Although an anal fissure appears to be a superficial skin tear, the process of its formation is not merely due to mechanical damage. Physiologically, the formation of this small crack occurs through the combination of several biological mechanisms such as muscle tension, impaired blood flow, and inter-tissue tension. The body indicates that it is not just a tear but that its balance has been disrupted. Prolonged constipation is the most common cause of anal fissures. When hardened stool passes through the anus, it stretches the skin in the area and causes tearing in the thin mucosa. Once this situation occurs, the area becomes sensitive, and the wound can reopen with repeated bowel movements. In infants, anal fissures usually arise after the passage of hard stool following constipation and can manifest with crying and restlessness that catches the attention of parents.
Spending a long time in the toilet or straining too much to pass stool increases pressure in the anal canal. This pressure creates tension on the vessels and can eventually lead to tissue tearing. This situation is more common in individuals who consume a low-fiber diet and do not drink enough water. Fissures are also associated with chronic diarrhea, as continuous bowel movements can irritate the mucosa in the area. Acidic or frequent stool passage can wear down the skin, weaken the thin skin, and eventually lead to small cracks. During childbirth, the pelvic area is also subjected to intense pressure. This situation can pave the way for the development of anal fissures after childbirth. Similarly, although rare, medical interventions or trauma to the anus can also cause fissures. In men, anal fissures are more frequently encountered in situations such as heavy lifting, constipation, and prolonged straining.
How is Anal Fissure Diagnosed?
The diagnosis process begins when the patient clearly expresses the symptoms they are experiencing to the physician. Details such as the nature of the pain during bowel movements, its duration, whether there is bleeding, and changes in toilet habits are quite decisive in the initial evaluation. Particularly, the characteristic of the pain starting during toilet use and continuing for a while afterward is a distinguishing feature for anal fissures. Additionally, the patient’s dietary habits, water intake, level of physical activity, and any chronic diseases are also taken into account. Because anal fissures are not just a mechanical tear, they are often the result of lifestyle habits. The doctor carefully examines the anal area to visually assess the presence of a fissure. In acute (newly formed) fissures, a thin, superficial tear is usually observed, typically located on the posterior midline. In chronic fissures, skin folds around the wound, thickened wound edges, or secondary lesions may be seen. This examination must be conducted carefully and meticulously because the pain experienced by the patient can lead to involuntary muscle contractions, making the examination experience more difficult. The diagnosis of acute anal fissure is often confirmed through physical examination, and no further investigation is required. However, if symptoms overlap with different diseases or if the wound does not heal within the expected time, more detailed evaluations may be necessary.
How is Anal Fissure Treated?
The treatment of anal fissures often begins with lifestyle changes, medical creams, and warm sitz baths. It is recommended to consume fiber-rich foods, drink enough water, and regulate toilet habits. Soften the stool for those suffering from constipation and preventing straining during bowel movements directly accelerates the healing of the wound. Similarly, behaviors such as prolonged sitting and excessive straining should be avoided.
In addition to these precautions, medical treatment is also sought. Some topical creams are used to reduce spasms in the muscles around the anus (especially the internal sphincter muscle). These medications relax the muscles in the area, increase blood circulation, and support the healing process. Local anesthetic creams may also be recommended to reduce pain, but these products are only used for symptom control and have limited direct therapeutic effects. In some cases, stool softeners may also be included in the process, which is particularly beneficial for individuals with a history of constipation.
If the fissure does not heal despite all these methods and the pain persists, more advanced treatment options are considered. One of these is the injection of botulinum toxin. This treatment, commonly known as “botox,” is applied to provide temporary relaxation of the internal sphincter muscle. With the relaxation of the muscle, blood circulation increases, allowing the wound to heal. The procedure is usually performed on an outpatient basis and its effects last for several months.
In the early stages, treatment of anal fissures can often be successfully completed without the need for surgery. In resistant and long-standing fissures, surgery for anal fissures can provide a permanent solution. Surgery is preferred especially in chronic fissures that do not improve despite all conservative approaches and significantly impair the quality of life. The most commonly performed procedure is a technique based on cutting a portion of the internal sphincter muscle called lateral internal sphincterotomy. This intervention permanently reduces muscle spasms and promotes wound healing. Within a few weeks after anal fissure surgery, pain significantly decreases, and bowel movement comfort is regained. Signs of healing from anal fissures can be observed as a reduction in pain, cessation of bleeding, and disappearance of post-bowel movement throbbing.
For patients seeking non-surgical methods, laser applications for anal fissures have gained prominence in recent years. Laser treatment for anal fissures is increasingly preferred by those seeking a less painful and shorter recovery process.
Frequently Asked Questions
How to Understand if There is a Fissure?
Anal fissures typically manifest with sharp, cutting-like pain that starts during bowel movements and continues afterward. Pain after bowel movements can last for minutes or even hours. The presence of bright red blood on toilet paper or in the stool is also a common finding. It may be accompanied by itching, irritation, and a feeling of discomfort around the anus.
What Happens if a Fissure is Not Treated?
If anal fissures are not treated, the likelihood of spontaneous healing generally decreases. In advanced cases affecting daily life, surgery for anal fissures can be an effective and permanent treatment option. As the process prolongs, a simple wound can become chronic. This leads to thickening of the wound edges, continuous spasms in the internal sphincter muscle, and impaired blood flow. In such a cycle, the wound reopens with every bowel movement, and the healing process resets. In the long term, this situation can lead not only to physical pain but also to fears related to bowel movements, social withdrawal, and serious losses in quality of life.
Does Anal Fissure Hurt While Sitting?
Especially during the active phase of an anal fissure, pain can occur not only during bowel movements but also while sitting. This pain is usually not sharp but rather throbbing and bothersome. It can be triggered by prolonged sitting, being on hard surfaces, or friction while walking. This situation can affect daily activities and reduce the quality of life, especially for those who work at desks.
What Does an Anal Fissure Look Like?
Anal fissures can be seen with the naked eye, but they are not easy to detect. The anal area is difficult to access and visually examine. Acute fissures are usually observed as a thin scratch or tear at the back of the anus. In chronic fissures, a skin fold (sentinel tag) may form at the edge of the wound, and the wound may be deepened and have thickened edges.
What Does Mucus-like Fluid from the Anus Mean?
Mucus-like fluid from the anus is usually a secretion known as mucus, which is a natural part of the digestive system. An abnormal increase in this secretion can indicate irritation, infection, or inflammatory bowel diseases (such as ulcerative colitis, Crohn’s disease). In anal fissures, mucus-like fluid may also come from the continuously irritated area. This fluid is transparent, sometimes yellowish, and rarely causes a bad odor.
Is Colonoscopy Done if There is an Anal Fissure?
Since the diagnosis of anal fissure can usually be made with a simple physical examination, colonoscopy is not required in the initial stage. In some special cases, especially if the fissure has become chronic, has not healed for a longer than expected time, or if age, history, and symptoms suggest other diseases such as colorectal cancer, colonoscopy may be considered.
What Causes Tissue-like Structures in Stool?
Anal fissures typically only lead to the presence of bright red, fresh blood in the stool due to being a superficial tear. Structures described as tissue in the stool are usually blood clots, debris from the intestinal mucosa, or tumorous structures. This situation can indicate serious intestinal inflammation, polyps, diverticular bleeding, or, although rarely, tumors. If there are accompanying findings such as changes in bowel habits, abdominal pain, or hidden blood loss, it is essential to consult a gastroenterology specialist and conduct necessary tests.
What Do White Round Pieces in Stool Mean?
Anal fissures do not directly cause such structures, but in patients with chronic fissures, the intestinal flora, toilet habits, and mucus secretion may change. This can lead to the occasional observation of abnormal pieces or tissue remnants in the stool. The white round structures observed in the stool are mostly associated with parasite eggs or worm segments. Although they are more commonly seen in children, they can also occur in adults. In some cases, these pieces may also be structures from the intestinal flora or undigested mucus remnants.
What Does a Gel-like Secretion in Stool Mean?
When anal fissures cause irritation and inflammation in the area during bowel movements, mucus production may increase. This secretion is usually seen mixed with stool and can resemble the consistency of egg white. The egg white-like secretion may be mucus released from the digestive system. This mucus is naturally produced to protect the inner surface of the large intestine, but an increase in its amount usually indicates irritation or inflammation. Conditions such as spastic colon (irritable bowel syndrome), infectious colitides, ulcerative colitis, and Crohn’s disease may lead to increased mucus secretion.
What is Transparent Secretion in Stool?
Transparent secretion in stool is mostly mucus and is a natural secretion that provides lubrication to the intestinal surface. If seen in significant amounts, this situation usually indicates irritation of the intestinal wall. This irritation can develop due to an infection, irritable bowel syndrome, inflammatory bowel disease, or a fissure in the anal area.
