Anal fissures can be an uncomfortable and distressing condition for many individuals. These small tears in the lining of the anal canal often cause pain and bleeding during bowel movements, making everyday activities challenging. While common, anal fissures are frequently misunderstood, leading to delayed treatment and unnecessary suffering.
This article explores the various types of anal fissures and offers insights into effective treatment approaches. It covers conservative methods for managing symptoms, as well as advanced techniques for more persistent cases. Additionally, it provides practical tips to help people living with anal fissures improve their quality of life and promote healing. By understanding this condition better, individuals can take steps to address anal fissures and find relief.
Types of Anal Fissures
Anal fissures can be classified based on their duration, underlying causes, and location. Understanding these different types of anal fissures is crucial for accurate diagnosis and effective treatment.
Acute vs. Chronic Fissures
Acute anal fissures are superficial tears that typically heal within 6 weeks with conservative treatment. They often present as a reddened, easily bleeding laceration in the anal canal. In contrast, chronic anal fissures persist for more than 6 weeks and may have thickened, raised edges with exposed muscle fibers underneath. Chronic fissures are often accompanied by a sentinel pile (external skin tag) at the distal end and a hypertrophied anal papilla at the proximal end.

Primary vs. Secondary Fissures
Primary or typical anal fissures have no clear underlying cause and are likely related to local trauma, such as hard stools or prolonged diarrhea. They are most commonly located in the posterior or anterior midline of the anal canal. Secondary or atypical fissures, on the other hand, are caused by an underlying condition, such as inflammatory bowel disease (Crohn’s disease), infections (tuberculosis, HIV/AIDS, syphilis), or malignancy. These fissures are often multiple or located in atypical positions (lateral or off the midline).
Location-Based Classification
Approximately 90% of anal fissures occur in the posterior midline, possibly due to the relatively poor blood supply in this area. Around 10% of fissures are located in the anterior midline and are more common in younger, mostly female patients. These anterior fissures may be associated with injury to or dysfunction of the external anal sphincter. Less than 1% of anal fissures are lateral or multiple, and their presence should raise suspicion for an underlying secondary cause.
Conservative Treatment Approaches
Conservative treatment approaches are often the first line of treatment for anal fissures. These non-invasive methods aim to promote healing, reduce pain, and prevent recurrence. The main components of conservative treatment include dietary modifications, topical medications, and sitz baths.
Dietary modifications play a crucial role in managing anal fissures. Increasing daily fiber intake by including plenty of high-fiber foods such as fruits, vegetables, and whole grains can help soften stools and reduce constipation. Staying hydrated by drinking plenty of water is also essential to prevent dry, hard stools. Regular exercise and establishing a consistent bowel routine can further aid in preventing constipation and straining during bowel movements.
Topical medications are commonly prescribed to alleviate symptoms and promote healing. Over-the-counter stool softeners can help reduce discomfort during bowel movements. Topical anesthetics, such as lidocaine, may be recommended to numb the anal area and provide temporary pain relief. Glyceryl trinitrate (GTN) ointment, a vasodilator, can be applied to the anal canal to increase blood flow and promote healing. However, headaches are a common side effect of GTN ointment, affecting up to half of the people who use it. Topical calcium channel blockers are an alternative to GTN ointment and work by relaxing the anal sphincter muscle.
Sitz baths are a simple yet effective conservative treatment for anal fissures. Soaking the anal area in warm water for 10-15 minutes, particularly after bowel movements, can help relax the anal sphincter muscles, increase blood flow to the area, and promote healing. Sitz baths can be done several times a day to alleviate pain and discomfort. Adding Epsom salts to the warm water may provide additional benefits due to their anti-inflammatory properties.
It is important to note that while conservative treatments are effective for most acute anal fissures, chronic fissures may require more advanced treatment methods. If conservative approaches do not provide relief within 6-8 weeks, it is advisable to consult with a healthcare provider to discuss further treatment options. Proper adherence to conservative treatment measures and maintaining a high-fiber diet and good bowel habits can help prevent recurrence of anal fissures.
Advanced Treatment Methods
Sphincterotomy
Lateral internal sphincterotomy is considered the gold standard surgical treatment for chronic anal fissures that do not respond to conservative therapies. The procedure involves making a small incision in the internal anal sphincter to reduce muscle tension and improve blood flow, allowing the fissure to heal.
Sphincterotomy has a high success rate, with over 90% of patients experiencing complete healing of their fissures within several weeks. However, the procedure carries a small risk of complications, such as bleeding, infection, and long-term incontinence. Patients with multiple fissures or underlying conditions may not be suitable candidates for sphincterotomy.
Other surgical options
In some cases, alternative surgical procedures may be recommended for treating chronic anal fissures. These include:
- Fissurectomy: This involves excising the fissure along with the surrounding scar tissue. Fissurectomy may be combined with sphincterotomy to improve healing rates.
- Advancement flap procedures: These techniques involve creating a flap of healthy tissue to cover the fissure, promoting healing and reducing pain. Advancement flaps may be considered for patients with multiple fissures or those at high risk of incontinence from sphincterotomy.
The choice of advanced treatment for chronic anal fissures depends on various factors, including the severity and duration of symptoms, the patient’s overall health, and the presence of underlying conditions. A thorough evaluation by a healthcare provider can help determine the most appropriate course of treatment for each individual case.
Living with Anal Fissures
Living with anal fissures can be challenging, as they can cause significant pain and discomfort during bowel movements. The pain may persist for hours after a bowel movement, making everyday activities difficult. In addition to the physical discomfort, anal fissures can also have an emotional impact on individuals, causing embarrassment and anxiety.
To manage the pain associated with anal fissures, individuals can take several steps. Soaking in warm baths, particularly after bowel movements, can help relax the anal sphincter muscles and promote healing. Over-the-counter pain relievers, such as acetaminophen or ibuprofen, may also provide relief. Applying topical anesthetics, such as lidocaine, can numb the area and reduce discomfort.
Maintaining a high-fiber diet and staying hydrated are crucial for preventing constipation and promoting soft stools, which can help reduce pain during bowel movements. Gradually increasing fiber intake through fruits, vegetables, whole grains, and fiber supplements can be beneficial. It is important to avoid straining during bowel movements, as this can worsen the fissure and delay healing.
The emotional impact of anal fissures should not be overlooked. Many individuals may feel embarrassed or anxious about their condition, which can lead to social isolation and a decreased quality of life. It is essential to remember that anal fissures are a common condition and that seeking medical help is important for proper treatment and relief.
Talking to a trusted healthcare provider can help alleviate concerns and provide guidance on managing the condition. Joining support groups, either in-person or online, can provide a sense of community and allow individuals to share their experiences and coping strategies with others who understand their situation.
There are several resources available for those living with anal fissures. Medical professionals, such as primary care physicians, gastroenterologists, and colorectal surgeons, can provide personalized treatment plans and advice. Patient education materials, such as brochures and websites from reputable healthcare organizations, can offer valuable information on self-care measures and treatment options.
