Lower Rectum Dysfunction refers to a range of conditions that affect the lower part of the rectum, leading to various symptoms that can impact daily life. Understanding its anatomy, causes, symptoms, diagnostic methods, treatments, and prevention strategies is crucial for effective management and improved quality of life.
Anatomy of the Lower Rectum
Structure
The lower rectum is the final segment of the large intestine, measuring about 12 centimeters. It connects the sigmoid colon to the anal canal. Its primary function is to store feces before they are expelled during bowel movements.
Blood Supply
The lower rectum receives blood primarily from the superior rectal artery, a branch of the inferior mesenteric artery. Additional blood comes from the middle and inferior rectal arteries, ensuring adequate blood flow for its functions.
Nerve Supply
The nerve supply to the lower rectum is crucial for controlling bowel movements and maintaining continence. It is provided by the pelvic splanchnic nerves (parasympathetic) and the hypogastric plexus (sympathetic). These nerves coordinate muscle contractions and relaxation during defecation.
Types of Lower Rectum Dysfunction
- Fecal Incontinence: Inability to control bowel movements, leading to accidental leakage.
- Rectal Prolapse: The rectum protrudes through the anus.
- Rectal Pain: Persistent or intermittent pain in the rectal area.
- Constipation: Difficulty in passing stools or infrequent bowel movements.
- Rectal Hyposensitivity: Reduced sensation in the rectum, affecting bowel control.
- Dyssynergia: Incoordination of pelvic muscles during defecation.
- Rectocele: Bulging of the rectum into the vagina.
- Hemorrhoids: Swollen blood vessels in the rectum or anus.
- Anal Fissures: Small tears in the lining of the anus.
- Pelvic Floor Dysfunction: Weakness or tightness in pelvic muscles affecting rectal function.
