Middle rectum obstruction refers to a blockage that occurs in the midsection of the rectum, the last part of the large intestine that connects to the anus. This obstruction can disrupt the normal flow of stool, leading to discomfort, pain, and other health issues. Understanding this condition involves knowing about the rectum’s anatomy, potential causes, symptoms, diagnostic methods, treatments, and prevention. This guide explains everything about middle rectum obstruction in simple, easy-to-understand language.
Anatomy of the Middle Rectum
The rectum is part of the digestive system located between the sigmoid colon and the anus. It measures about 12-15 cm in length. The middle portion of the rectum lies approximately 5-8 cm above the anus.
Structure
- Layers of the Rectum:
- Mucosa: The innermost layer that absorbs water and contains mucus-producing cells.
- Submucosa: Contains blood vessels, nerves, and connective tissue.
- Muscle Layer: Responsible for the contraction that moves stool toward the anus.
- Serosa: The outermost protective layer.
Blood Supply
- The rectum receives blood from three main arteries:
- Superior rectal artery (from the inferior mesenteric artery)
- Middle rectal artery (from the internal iliac artery)
- Inferior rectal artery (from the internal pudendal artery)
Nerve Supply
- The rectum is innervated by:
- Autonomic nerves: Sympathetic and parasympathetic nerves control involuntary functions like contraction and relaxation.
- Somatic nerves: These control voluntary actions like defecation.
Types of Middle Rectum Obstruction
There are several types of rectal obstructions based on the underlying cause:
- Mechanical Obstruction: Physical blockage, such as a tumor or foreign object.
- Functional Obstruction: The rectum fails to function properly without a physical blockage.
- Partial Obstruction: The rectum is partially blocked, causing difficulty in passing stool.
- Complete Obstruction: Total blockage that prevents any stool from passing.
