A middle rectum fistula is an abnormal connection that forms between the rectum (the last part of the large intestine) and another part of the body, such as the skin or an organ like the bladder or vagina. This fistula can cause various complications, including infections, pain, and difficulty with bowel movements. In this article, we will explore the anatomy involved, the different types of rectal fistulas, their causes, symptoms, diagnostic methods, treatments, and much more. This detailed description aims to simplify the understanding of rectal fistulas for general readers while ensuring it’s search engine optimized (SEO) for better readability and visibility.
Anatomy of the Middle Rectum Fistula
Rectum Structure: The rectum is a part of the digestive system, located at the end of the large intestine. It acts as a temporary storage site for stool before it’s passed out of the body during a bowel movement. It measures about 12–15 cm (4.7–5.9 inches) in length and is supported by the pelvic floor muscles.
Blood Supply: The rectum receives blood from several arteries:
- Superior rectal artery: Supplies the upper part of the rectum.
- Middle rectal artery: Supplies the middle section of the rectum.
- Inferior rectal artery: Supplies the lower section of the rectum and the anal canal.
Nerve Supply: The rectum’s nerves are responsible for regulating the sensation of fullness and the control of bowel movements. These nerves are part of the autonomic nervous system:
- Sympathetic nerve supply: Helps in controlling the contraction of the rectal muscles.
- Parasympathetic nerve supply: Responsible for stimulating bowel movements and relaxation of the rectal muscles.
Types of Rectal Fistulas
- Intersphincteric Fistula: Located between the internal and external sphincter muscles.
- Transsphincteric Fistula: Passes through both the internal and external sphincters, creating a path from the rectum to the skin.
- Suprasphincteric Fistula: Bypasses the sphincter muscles, creating a longer and more complex path.
- Extrasphincteric Fistula: Extends from the rectum to other organs, such as the bladder or vagina.
- Horseshoe Fistula: Forms a U-shape, circling the rectum.
