What are the management options for prolapsed internal hemorrhoids?

Management of Prolapsed Internal Hemorrhoids

For prolapsed internal hemorrhoids, treatment should follow a stepwise approach starting with conservative measures and manual reduction for grade III hemorrhoids, progressing to procedural interventions like rubber band ligation for persistent symptoms, and reserving surgical options for grade IV hemorrhoids or those that fail less invasive approaches. 1

Classification and Assessment

Internal hemorrhoids are classified by degree of prolapse:

• Grade I: Bleed but do not protrude
• Grade II: Protrude with defecation but reduce spontaneously
• Grade III: Protrude and require manual reduction
• Grade IV: Permanently prolapsed and cannot be reduced 1

Conservative Management (First-Line)

For all grades of hemorrhoids, especially grade III that can still be manually reduced:

• Dietary modifications:

  • Increase fiber intake to 25-30g daily
  • Ensure adequate hydration (8-10 glasses of water daily)
  • Consider bulk-forming agents (psyllium husk, methylcellulose) 1

• Lifestyle modifications:

  • Avoid straining during defecation
  • Avoid prolonged sitting
  • Regular physical activity to promote bowel regularity 1

• Symptomatic relief:

  • Sitz baths 2-3 times daily
  • Topical treatments (hydrocortisone preparations) for pain and inflammation
  • Mesalamine suppositories (shown superior efficacy compared to placebo) 1

Manual Reduction

For incarcerated rectal prolapse without signs of ischemia or perforation:

• Attempt gentle manual reduction under mild sedation or anesthesia 2
• This is particularly important for grade III hemorrhoids that require manual reduction

Office-Based Procedures

If conservative management fails, consider:

1. Rubber Band Ligation (preferred first-line procedural treatment):

   • Most effective office-based procedure for grades I-III hemorrhoids
   • Resolves symptoms in 89% of patients
   • Up to 20% may require repeated procedures 1, 3

2. Alternative office procedures:

   • Sclerotherapy: 70-85% short-term efficacy but only one-third achieve long-term remission
   • Infrared coagulation: 70-80% success in reducing bleeding and prolapse 1, 3
   • Hemorrhoidal artery ligation: Useful for grade II-III hemorrhoids with less pain and quicker recovery 1

Surgical Management

Reserved for:

• Grade IV hemorrhoids
• Failed conservative and office-based treatments
• Complicated cases (strangulation, thrombosis)

Surgical options:

1. Excisional hemorrhoidectomy:

   • Gold standard for grade IV hemorrhoids
   • Lower recurrence rate (2-10%)
   • Longer recovery period (9-14 days) 1, 3

2. Stapled hemorrhoidopexy:

   • Faster recovery than traditional hemorrhoidectomy
   • Higher recurrence rate
   • Elevates grade III or IV hemorrhoids to normal anatomic position 4

Management of Complications

For strangulated or thrombosed hemorrhoids:

• If signs of shock, gangrene, or perforation: immediate surgical treatment 2
• For bleeding, acute obstruction, or failed non-operative management: urgent surgical treatment 2
• Consider empiric antimicrobial therapy for strangulated cases due to risk of bacterial translocation 2

Post-Treatment Care

After procedural or surgical intervention:

• Pain management with NSAIDs
• Continued fiber supplements
• Sitz baths 2-3 times daily
• Stool softeners to prevent constipation
• Monitor for complications: bleeding (0.03-6%), urinary retention (2-36%), infection (0.5-5.5%) 1

Special Considerations

• Pregnancy: Conservative management preferred; surgery only if absolutely necessary
• Immunocompromised patients: Higher infection risk with procedures
• Inflammatory bowel disease: Extreme caution with surgical interventions due to high rate of complications
• Liver cirrhosis/portal hypertension: Distinguish anal varices from hemorrhoids 1

Treatment Algorithm

1. Start with conservative measures for all grades of prolapsed hemorrhoids
2. For grade III hemorrhoids: Attempt manual reduction
3. If symptoms persist: Proceed to rubber band ligation
4. For grade IV or failed treatments: Consider surgical options (excisional hemorrhoidectomy preferred)

Remember that early intervention for prolapsed hemorrhoids can prevent progression to more severe complications requiring extensive surgical procedures.
