A middle rectal valve fistula is a rare medical condition where an abnormal passage or tunnel (fistula) forms between the middle rectal valve (part of the rectum) and another organ, usually the vagina, bladder, or perineum. This condition can lead to various symptoms that disrupt normal bodily functions and require medical treatment.
Anatomy of the Middle Rectal Valve Fistula
Structure
- Middle Rectal Valve: The rectum has three main rectal valves, also known as valves of Houston. These are folds of tissue that help slow down stool passage. The middle rectal valve is located roughly in the middle of the rectum.
- Fistula Formation: In a middle rectal valve fistula, a tube-like passage develops between the rectum and another body part.
- Tissue Involvement: The fistula typically passes through the rectal wall, often involving muscle layers and mucosal lining.
Blood Supply
- The middle rectal valve receives blood from the middle rectal artery, which is a branch of the internal iliac artery. Venous drainage is primarily through the middle rectal vein.
Nerve Supply
- The rectum, including the middle rectal valve, is supplied by autonomic nerves, primarily through the inferior hypogastric plexus. This nerve supply is essential for sensory and motor functions.
Types of Middle Rectal Valve Fistula
- Rectovaginal Fistula: Between the rectum and vagina.
- Rectovesical Fistula: Between the rectum and bladder.
- Rectourethral Fistula: Between the rectum and urethra.
- Rectoperineal Fistula: Between the rectum and skin of the perineum.
- Complex Fistulas: Involve multiple connections or intricate pathways.
