Rectosigmoid junction obstruction is a medical condition affecting the area where the rectum meets the sigmoid colon. This guide provides detailed yet straightforward information on its anatomy, types, causes, symptoms, diagnostic methods, treatments, and more. Whether you’re a patient, caregiver, or just curious,
Anatomy of the Rectosigmoid Junction
Understanding the anatomy helps in comprehending how obstructions occur.
Structure
- Rectum: The final straight portion of the large intestine, ending at the anus.
- Sigmoid Colon: An S-shaped section of the large intestine leading into the rectum.
- Rectosigmoid Junction: The area where the sigmoid colon transitions into the rectum.
Blood Supply
- Superior Rectal Artery: Supplies blood to the rectum.
- Middle and Inferior Rectal Arteries: Supply blood to the lower parts, including the rectosigmoid junction.
Nerve Supply
- Autonomic Nervous System: Controls involuntary functions like bowel movements.
- Sensory Nerves: Provide sensation in the rectosigmoid area.
Types of Rectosigmoid Junction Obstruction
- Mechanical Obstruction: Physical blockage due to tumors, strictures, or impacted stool.
- Functional Obstruction: Impaired movement without a physical blockage, often due to nerve or muscle problems.
- Pseudo-Obstruction: Symptoms mimic blockage but no actual physical obstruction exists.
Causes of Rectosigmoid Junction Obstruction
Here are 20 possible causes:
