Anal Pectinate Fissures

Anal pectinate fissures are small tears or cracks in the lining of the anus. These fissures can cause pain and bleeding, especially during bowel movements. Understanding their causes, symptoms, and treatment options can help manage and prevent this condition effectively.

Anal pectinate fissures are tiny tears in the mucosal lining of the anal canal. They often result from trauma to the anal area, such as passing hard stools or during childbirth. These fissures can be acute (short-term) or chronic (long-lasting) and may lead to discomfort and bleeding.

Anatomy of the Anal Region

Structure

The anal region consists of several key structures:

• Anal Canal: The final part of the digestive tract, about 2.5 to 4 cm long.
• Anus: The opening through which stool exits the body.
• Sphincters: Muscles that control the opening and closing of the anus.
  • Internal Sphincter: Involuntary muscle providing constant closure.
  • External Sphincter: Voluntary muscle allowing control over bowel movements.

Blood Supply

The blood supply to the anal region comes primarily from:

• Superior Rectal Artery: Supplies the upper part.
• Middle Rectal Artery: Supplies the middle area.
• Inferior Rectal Artery: Supplies the lower part of the anal canal.

Nerve Supply

Nerve supply is crucial for sensation and control:

• Pudendal Nerve: Provides sensation and controls the external sphincter.
• Autonomic Nerves: Control involuntary functions like internal sphincter relaxation.

Types of Anal Pectinate Fissures

Anal fissures can be categorized based on their duration and characteristics:

1. Acute Fissures: Recent tears causing immediate pain and bleeding.
2. Chronic Fissures: Long-standing fissures with possible scar tissue formation.
3. Anterior Fissures: Located at the front of the anus, more common in women.
4. Posterior Fissures: Located at the back of the anus, more common in men.
