Lower rectum fissures, commonly known as anal fissures, are small tears in the lining of the anus. These fissures can cause significant discomfort and pain, especially during bowel movements. Understanding the anatomy, causes, symptoms, and treatment options can help manage and prevent this condition effectively.
Lower rectum fissures, or anal fissures, are small tears in the thin, moist tissue lining the anus. They often occur when passing hard or large stools, leading to pain and bleeding during bowel movements. While common and usually not serious, chronic fissures can lead to more significant health issues if left untreated.
Anatomy of the Lower Rectum
Structure
The lower rectum is the final section of the large intestine, leading to the anus. The anal canal is surrounded by muscles called sphincters that control bowel movements. The lining of the anus is delicate and can be prone to tearing under stress.
Blood Supply
The lower rectum receives blood from the superior rectal artery, which branches into the middle and inferior rectal arteries. Proper blood flow is essential for healing fissures.
Nerve Supply
Nerves in the lower rectum provide sensation and control to the anal area. Damage or irritation to these nerves can affect bowel movement sensations and pain levels.
Types of Lower Rectum Fissures
- Acute Fissures: Recent tears that heal quickly with proper care.
- Chronic Fissures: Long-standing tears that may not heal properly, often lasting more than six weeks.
- Posterior Fissures: Located at the back of the anus, more common due to less elasticity.
- Anterior Fissures: Located at the front of the anus, less common and typically less painful.
Causes of Lower Rectum Fissures
