Rectal Prolapse: Causes, Symptoms, and Treatment - Surgery

More Info

---

Rectal prolapse is a condition where part of the rectum protrudes through the anus. It can occur in varying degrees, from a small amount of tissue that only comes out during bowel movements to a complete prolapse where the entire rectum is outside the body. Understanding the causes, symptoms, and treatment options for rectal prolapse is essential for effective management.


Causes
Rectal prolapse can be caused by several factors, including:
1. Weakness of Pelvic Floor Muscles: The pelvic floor muscles support the rectum and can weaken due to age, childbirth, or chronic straining during bowel movements.

2. Chronic Constipation or Diarrhea: Frequent straining to pass stool or prolonged diarrhea can put pressure on the rectal area, leading to prolapse.

3. Neurological Conditions: Conditions that affect nerve function, such as spinal cord injuries or multiple sclerosis, can impair the ability to control bowel movements, contributing to prolapse.

4. Previous Surgery: Surgical procedures in the pelvic area can sometimes lead to changes in muscle tone and support, increasing the risk of prolapse.

5. Genetic Factors: Some individuals may have a genetic predisposition to weaker connective tissue, making them more susceptible to prolapse.


Symptoms
The primary symptom of rectal prolapse is the visible protrusion of rectal tissue, which may occur during bowel movements. Other symptoms can include:
- A feeling of fullness or pressure in the rectal area.

- Mucous discharge from the rectum.

- In some cases, a sensation of incomplete bowel evacuation.

- Occasionally, there may be discomfort or pain, but as you mentioned, it can be painless.


Diagnosis
Diagnosis typically involves a physical examination by a healthcare provider. They may ask about your symptoms, medical history, and perform a rectal examination to assess the extent of the prolapse. In some cases, additional tests such as colonoscopy may be recommended to rule out other conditions.


Treatment
Treatment options for rectal prolapse depend on the severity of the condition and the symptoms experienced. Here are some common approaches:
1. Conservative Management: For mild cases, lifestyle changes such as dietary modifications to prevent constipation, pelvic floor exercises, and avoiding straining during bowel movements can be beneficial. Increasing fiber intake and hydration can help maintain regular bowel movements.

2. Medications: If constipation is a contributing factor, laxatives or stool softeners may be prescribed to ease bowel movements.

3. Surgical Options: If conservative measures are ineffective or if the prolapse is severe, surgical intervention may be necessary. Surgical options include:
- Rectopexy: This procedure involves attaching the rectum to the surrounding tissues to prevent it from prolapsing.

- Resection: In some cases, a portion of the rectum may be removed, especially if there are associated complications.

4. Follow-Up Care: Regular follow-up with a healthcare provider is essential to monitor the condition and adjust treatment as necessary.


Conclusion
While rectal prolapse can be concerning, especially when it occurs consistently during bowel movements, it is often manageable with appropriate treatment. Since you mentioned that the tissue protrudes only during bowel movements and resolves afterward without pain or bleeding, it may indicate a mild case. However, it is crucial to consult with a healthcare provider for a thorough evaluation and to discuss the best management plan tailored to your specific situation. Early intervention can help prevent the condition from worsening and improve your quality of life.
