Rectal obstruction is a medical condition where the normal passage of stool through the rectum is blocked. This blockage can occur due to various reasons, leading to difficulty in bowel movements, pain, and other symptoms. It can be acute (sudden) or chronic (long-lasting) and may require immediate medical attention.
Anatomy of the Rectum
Understanding the rectum’s anatomy helps in comprehending how obstructions occur.
Structure
The rectum is the final section of the large intestine, connecting the colon to the anus. It measures about 12 centimeters in length and serves as a temporary storage site for feces before elimination.
Blood Supply
The rectum receives blood through the superior, middle, and inferior rectal arteries, which are branches of the inferior mesenteric and internal iliac arteries. Adequate blood flow is crucial for rectal health and function.
Nerve Supply
The rectum is innervated by the autonomic nervous system, including the inferior hypogastric plexus. This nerve supply controls muscle contractions and sensation, facilitating bowel movements.
Types of Rectal Obstruction
Rectal obstructions can be categorized based on their location and cause:
- Mechanical Obstruction: Physical blockage preventing stool passage.
- Functional Obstruction (Pseudo-Obstruction): Impaired bowel movement without a physical blockage, often due to nerve or muscle problems.
- Partial Obstruction: Allows some stool to pass, causing intermittent symptoms.
- Complete Obstruction: Completely blocks stool passage, leading to severe symptoms.
Causes of Rectal Obstruction
Rectal obstruction can result from various conditions. Here are 20 possible causes:
- Colorectal Cancer: Tumors blocking the rectal passage.
- Benign Polyps: Non-cancerous growths causing blockage.
