Anal Valves Injury 

Anal valves, also known as anal cushions, play a crucial role in our digestive system. They help control bowel movements by regulating the passage of stool. However, injuries to these valves can lead to discomfort, pain, and various complications. This article provides a detailed yet straightforward overview of anal valves injury, covering anatomy, types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, prevention, and frequently asked questions.

Anatomy of Anal Valves

Structure

Anal valves are folds of mucous membrane located in the anal canal, the final segment of the large intestine. Typically, there are three main anal valves:

1. First Anal Valve (Lower Valve): Closest to the anus.
2. Second Anal Valve (Middle Valve): Located above the first.
3. Third Anal Valve (Upper Valve): Closest to the rectum.

These valves help maintain continence by closing tightly to prevent stool leakage and opening to allow stool passage during defecation.

Blood Supply

Anal valves receive blood through:

• Superior Rectal Artery: Supplies the upper parts.
• Middle Rectal Artery: Supplies the middle sections.
• Inferior Rectal Artery: Supplies the lower parts near the anus.

Proper blood flow is essential for the health and function of anal valves.

Nerve Supply

The nerve supply to anal valves includes:

• Autonomic Nerves: Control involuntary functions like muscle contraction.
• Somatic Nerves: Responsible for voluntary control over the external anal sphincter.

These nerves enable the anal valves to respond to internal and external stimuli, maintaining control over bowel movements.

Types of Anal Valves Injury

Anal valves injuries can be classified based on their nature and severity:

1. Traumatic Injuries:
   • Caused by accidents, surgeries, or childbirth.
2. Inflammatory Injuries:
   • Result from conditions like hemorrhoids or infections.
3. Degenerative Injuries:
   • Occur due to aging or chronic conditions affecting tissue elasticity.
4. Ischemic Injuries:
   • Caused by reduced blood flow leading to tissue damage.
5. Iatrogenic Injuries:
   • Result from medical procedures or treatments gone wrong.
6. Chemical Injuries:
   • Caused by exposure to harmful chemicals or substances.
7. Radiation Injuries:
   • Result from radiation therapy used in cancer treatment.

Understanding the type of injury is crucial for effective treatment and management.

Causes of Anal Valves Injury

Anal valves injuries can arise from various factors. Here are 20 potential causes:

1. Childbirth:
   • Vaginal delivery can stretch or tear anal tissues.
2. Trauma:
