Anal fissures are small tears in the lining of the anus that can cause pain and bleeding during bowel movements. Specifically, external anal sphincter fissures occur in the outer muscle surrounding the anus. Understanding this condition, its causes, symptoms, and treatments can help manage and prevent discomfort.
External anal sphincter fissures are tears in the external part of the anal sphincter muscle, which controls the opening and closing of the anus. These fissures can lead to pain, bleeding, and discomfort, especially during bowel movements.
Anatomy of the Anal Sphincter
Understanding the anatomy helps in comprehending how fissures occur and their impact.
Structure
The anal sphincter consists of two main muscles:
- Internal Anal Sphincter (IAS): Involuntary muscle controlling the majority of anal closure.
- External Anal Sphincter (EAS): Voluntary muscle allowing control over bowel movements.
Blood Supply
- Superior Rectal Artery: Supplies the internal sphincter.
- Inferior Rectal Artery: Supplies the external sphincter.
Nerve Supply
- Autonomic Nervous System: Controls involuntary movements via the internal sphincter.
- Somatic Nervous System: Controls voluntary movements via the external sphincter.
Types of Anal Fissures
Anal fissures can be classified based on their location and characteristics:
- Acute Fissures: Recent tears causing sharp pain.
- Chronic Fissures: Long-standing fissures with scar tissue and reduced healing.
- External Fissures: Located in the external anal sphincter.
- Internal Fissures: Located inside the anal canal.
Causes of External Anal Sphincter Fissures
Multiple factors can lead to the development of external anal sphincter fissures. Here are 20 potential causes:
- Constipation: Straining during bowel movements.
- Diarrhea: Frequent, loose stools irritating the anus.
