A lower rectum fistula is an abnormal connection between the lower part of the rectum and other organs or the skin. Understanding this condition involves knowing the anatomy, types, causes, symptoms, diagnostic methods, treatments, prevention strategies, and when to seek medical help. This guide provides detailed yet straightforward information to help you grasp everything you need to know about lower rectum fistulas.
A lower rectum fistula is an abnormal tunnel that forms between the lower rectum and another part of the body, such as the skin near the anus, the vagina, or other organs. This connection allows the passage of stool, gas, or fluids, leading to various health issues.
Key Points:
- Abnormal Connection: Fistulas are not natural and form due to underlying problems.
- Common Locations: Near the anus (perianal), between the rectum and vagina (rectovaginal), or with other organs.
Anatomy of the Lower Rectum
Understanding the lower rectum’s anatomy helps in comprehending how fistulas develop.
Structure
- Rectum: The final section of the large intestine, storing stool before elimination.
- Anus: The opening at the end of the rectum through which stool exits the body.
Blood Supply
- Superior Rectal Artery: Supplies blood to the upper rectum.
- Middle and Inferior Rectal Arteries: Supply the lower rectum and anal canal.
Nerve Supply
- Autonomic Nerves: Control involuntary functions like blood flow.
- Somatic Nerves: Manage voluntary movements, such as controlling the anal sphincter.
Types of Lower Rectum Fistulas
Fistulas are classified based on their location and connections.
- Perianal Fistula: Connects the anal canal to the skin near the anus.
- Rectovaginal Fistula: Links the rectum to the vagina.
- Rectourethral Fistula: Connects the rectum to the urethra.
- Rectovaginal Fistula: Links the rectum to the bladder.
