Treatment of Incarcerated Hemorrhoids
Surgical intervention is the recommended treatment for incarcerated hemorrhoids (fourth-degree hemorrhoids), as these permanently prolapsed hemorrhoids cannot be reduced and require definitive management. 1
Classification and Diagnosis
Incarcerated hemorrhoids are classified as fourth-degree hemorrhoids in the Banov classification system. These are characterized by:
- Permanently prolapsed internal hemorrhoids that cannot be reduced
- May include both internal and external components
- May become thrombosed or gangrenous if left untreated 2, 1
Before proceeding with treatment, proper diagnosis is essential and should include:
- External examination to confirm irreducible prolapse
- Anoscopy with adequate light source to evaluate the extent of the condition
- Assessment for concomitant conditions (20% of hemorrhoid patients have anal fissures) 2
Treatment Algorithm
1. Immediate Management
- Pain control with NSAIDs and topical analgesics
- Sitz baths to reduce swelling and discomfort
- Ice packs to reduce edema
- Stool softeners to prevent further irritation during defecation 3
2. Definitive Treatment
For incarcerated (fourth-degree) hemorrhoids, surgical intervention is required:
Surgical Options:
Excisional Hemorrhoidectomy (preferred for incarcerated hemorrhoids)
Stapled Hemorrhoidopexy
Special Considerations
Thrombosed Incarcerated Hemorrhoids
If the incarcerated hemorrhoid is also thrombosed:
- Urgent surgical intervention is recommended
- Excisional hemorrhoidectomy is preferred over stapled techniques 1, 6
High-Risk Patients
Exercise caution in:
- Pregnant women: Consider conservative management when possible; surgery only if absolutely necessary
- Immunocompromised patients: Higher risk of infection; require careful perioperative management
- Patients on anticoagulants: May need medication adjustment before surgery
- Patients with portal hypertension/cirrhosis: Distinguish between hemorrhoids and rectal varices; standard hemorrhoidal treatments should not be used for varices 2, 1, 6
- Patients with inflammatory bowel disease: High rate of postoperative complications 1
Postoperative Care
- Pain management: NSAIDs, narcotics as needed, fiber supplements, topical antispasmodics
- 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%)
- Long-term follow-up to assess for recurrence or anal stenosis (0-6%) 1, 7
Common Pitfalls to Avoid
- Misdiagnosis: Ensure the condition is truly incarcerated hemorrhoids and not rectal prolapse or rectal varices
- Delayed treatment: Incarcerated hemorrhoids can become gangrenous if treatment is delayed
- Inadequate pain control: Postoperative pain is significant and requires multimodal analgesia
- Overlooking concomitant conditions: Check for anal fissures, abscesses, or other pathology
- Inappropriate surgical technique: Choose the appropriate surgical approach based on the specific presentation and patient factors 2, 1
Remember that while conservative measures are appropriate for lower-grade hemorrhoids, incarcerated (fourth-degree) hemorrhoids require surgical intervention for definitive treatment and to prevent serious complications.
