Middle rectum prolapse, also known as rectal prolapse, is a condition where part or all of the wall of the rectum slides out of its normal position, potentially extending outside the anus. This condition is more common in older adults, especially women, but can occur in men and children as well.
Below, I’ll provide a detailed yet easy-to-understand guide covering the anatomy of the rectum, the types of prolapse, causes, symptoms, diagnostic tests, treatment options, medications, surgeries, preventive measures, and when to seek medical attention.
Anatomy of the Rectum
The rectum is the final section of the large intestine, measuring about 12-15 cm in length. It connects the colon to the anus and plays a critical role in storing and expelling stool during bowel movements.
Structure of the Rectum:
- Mucosa: The innermost layer, consisting of epithelial cells that secrete mucus.
- Submucosa: A layer containing blood vessels, nerves, and connective tissue.
- Muscularis: Two layers of muscle that contract and push stool out of the body.
- Serosa: The outermost layer, acting as a protective barrier.
Blood Supply:
- Superior Rectal Artery: Provides most of the blood supply to the rectum.
- Middle Rectal Artery: Supplies the middle part of the rectum.
- Inferior Rectal Artery: Supplies the lower portion of the rectum.
Nerve Supply:
- Sympathetic Nerves: Help control the muscles that retain stool.
- Parasympathetic Nerves: Trigger the muscles involved in expelling stool.
Types of Rectal Prolapse
- Complete Prolapse (Full-thickness Prolapse): The entire wall of the rectum slides out through the anus.
- Mucosal Prolapse: Only the lining (mucosa) of the rectum protrudes.
- Internal Prolapse (Intussusception): The rectum folds into itself but does not extend outside the anus.
Causes of Rectal Prolapse
There are several factors that may contribute to the development of rectal prolapse, including:
- Chronic constipation
- Straining during bowel movements
- Weak pelvic floor muscles
- Aging (especially in women)
- History of vaginal childbirth
- Nerve damage (from childbirth, surgery, or trauma)
- Rectal or anal surgery
- Long-term diarrhea
- Neurological diseases (such as multiple sclerosis or spinal cord injuries)
- Connective tissue disorders (e.g., Ehlers-Danlos syndrome)
- Cystic fibrosis
- Malnutrition or low body weight
- Chronic coughing (from conditions like COPD or asthma)
- Repeated heavy lifting
- History of pelvic or abdominal surgery
- Obesity
- Genetics (family history of prolapse)
- Prolonged sitting or standing
- Weak rectal muscles due to aging or illness
- A history of anal intercourse or other trauma to the area.
Symptoms of Rectal Prolapse
The symptoms of rectal prolapse vary depending on the severity and type, but they commonly include:
- A visible protrusion of tissue from the anus (especially after bowel movements)
- Feeling a bulge in the rectum
- Pain or discomfort in the anal area
- Difficulty with bowel movements
- Chronic constipation
- Inability to control bowel movements (fecal incontinence)
- Mucus or blood discharge from the anus
- Sensation of incomplete evacuation after bowel movements
- Rectal bleeding
- Rectal pain
- Anal itching or irritation
- Frequent urge to defecate
- A feeling of heaviness or pressure in the pelvic area
- Leakage of stool (accidental bowel movements)
- Passing small amounts of stool frequently
- Difficulty holding in gas or stool
- Loss of sensation in the rectum
- Swelling or redness around the anus
- Urinary incontinence (in severe cases)
- Difficulty passing urine (if the prolapse presses on the bladder).
Diagnostic Tests for Rectal Prolapse
If rectal prolapse is suspected, a doctor may recommend several tests to confirm the diagnosis and determine the extent of the condition:
- Physical Exam: The doctor may see the prolapse by asking the patient to strain during the exam.
- Digital Rectal Exam: The doctor uses a gloved finger to feel for abnormalities in the rectum.
- Anoscopy: A small tube with a light is inserted into the anus to examine the lower rectum.
- Sigmoidoscopy: A flexible tube with a camera is used to look inside the lower colon and rectum.
- Colonoscopy: A long, flexible tube examines the entire colon and rectum.
- Defecography: A special X-ray that shows how well the rectum is working during bowel movements.
- Magnetic Resonance Imaging (MRI): Provides detailed images of the pelvic organs.
- CT Scan: Uses X-rays to create detailed pictures of the rectum and surrounding tissues.
- Ultrasound (Endoanal Ultrasound): Uses sound waves to create images of the rectum and anal sphincter muscles.
- Pelvic Floor Function Tests: Measures how well the muscles and nerves in the pelvic floor are functioning.
- Anorectal Manometry: Measures the strength of the muscles used during defecation.
- Electromyography (EMG): Tests the electrical activity of muscles in the rectum and anus.
- Barium Enema: A special dye is used to highlight the rectum and colon on X-rays.
- Evacuation Proctography: Measures how much of the rectum can empty during a bowel movement.
- Dynamic Pelvic MRI: Captures images of the pelvis during movement.
- Stool Tests: Can rule out infections that may cause symptoms similar to prolapse.
- Bladder Function Tests: If urinary symptoms are present, tests may assess bladder function.
- Neurological Tests: May be conducted if nerve damage is suspected.
- Biofeedback Evaluation: Tests how well the pelvic muscles are being used.
- Transit Time Study: Assesses how quickly food moves through the colon.
Non-Pharmacological Treatments
Non-surgical, non-medication treatments can be helpful, especially for mild cases. These include:
- Dietary Changes: Increasing fiber intake to soften stools.
- Drinking Plenty of Water: Staying hydrated helps ease constipation.
