Rectosigmoid Junction Fistulas 

A rectosigmoid junction fistula is an abnormal connection between the rectum and the sigmoid colon, which are parts of the large intestine. Understanding this condition involves knowing its anatomy, types, causes, symptoms, diagnostic methods, treatments, surgeries, prevention strategies, and when to seek medical help. This guide breaks down all these aspects in simple language to help you grasp the essentials.

Anatomy of the Rectosigmoid Junction

Understanding the anatomy helps in comprehending how a fistula forms.

• Rectum: The final section of the large intestine, ending at the anus. It stores stool before it exits the body.
• Sigmoid Colon: The S-shaped last part of the colon leading into the rectum. It helps transport stool to the rectum.
• Rectosigmoid Junction: The area where the sigmoid colon meets the rectum.

Blood Supply:

• Superior Rectal Artery: Supplies blood to the rectum.
• Sigmoid Artery: Supplies blood to the sigmoid colon.

Nerve Supply:

• Autonomic Nervous System: Controls involuntary functions like bowel movements.
• Somatic Nerves: Provide sensation to the area.

2. Rectovaginal Fistula: Connects the rectum to the vagina.
3. Rectocutaneous Fistula: Connects the rectum to the skin.
4. Colovesical Fistula: Connects the colon to the bladder.
