What are the surgical indications for hemorrhoids?

Surgical Indications for Hemorrhoids

Surgical hemorrhoidectomy is indicated for: (1) symptomatic grade III or IV hemorrhoids, (2) failure of conservative and office-based treatments, (3) mixed internal and external hemorrhoids, (4) hemorrhoids with concomitant anorectal pathology requiring surgery (fissure, fistula), and (5) hemorrhoidal bleeding causing anemia. 1

Grade-Based Surgical Algorithm

Grade I-II Hemorrhoids

• Surgery is not indicated for low-grade hemorrhoids 1, 2
• These respond well to conservative management (fiber, fluids) and office procedures like rubber band ligation (70.5-89% success rate) 1
• Rubber band ligation is more effective than sclerotherapy and requires fewer repeat treatments 1

Grade III Hemorrhoids

• Surgical intervention becomes appropriate when office-based procedures fail 1, 3
• Options include rubber band ligation, excisional hemorrhoidectomy, or stapled hemorrhoidopexy 3
• Conventional excisional hemorrhoidectomy is the most effective treatment with only 2-10% recurrence rate, particularly for symptomatic grade III disease 1, 4
• The trade-off: rubber band ligation causes less postoperative pain but has higher recurrence rates compared to surgical excision 3

Grade IV Hemorrhoids

• Excisional hemorrhoidectomy or stapled hemorrhoidopexy is recommended as definitive treatment 3
• Conventional excisional hemorrhoidectomy (Ferguson closed or Milligan-Morgan open technique) is the gold standard with 2-10% recurrence 1, 4
• Non-reducible prolapsing hemorrhoids require surgical excision as the only viable option 2

Specific Clinical Scenarios Requiring Surgery

Hemorrhoidal Bleeding with Anemia

• Hemorrhoidectomy is mandated when hemorrhoidal bleeding causes anemia 1
• Active bleeding on anoscopy with low hemoglobin indicates substantial chronic blood loss requiring definitive surgical control 1
• Critical pitfall: Never attribute anemia to hemorrhoids without colonoscopy to rule out proximal colonic pathology 1

Mixed Internal and External Hemorrhoids

• Surgery is indicated when both internal and external components are symptomatic 1
• Office procedures cannot adequately address the external component 1

Concomitant Anorectal Pathology

• Surgery is required when hemorrhoids coexist with conditions requiring operative intervention (anal fissure, fistula, significant skin tags) 1, 5
• These combined pathologies cannot be effectively managed with conservative or office-based approaches 5

Thrombosed or Strangulated Hemorrhoids

• Urgent hemorrhoidectomy is a safe option for incarcerated, gangrenous, or acutely thrombosed hemorrhoids 4, 6
• Emergency hemorrhoidectomy achieves the same results as elective surgery 5
• For thrombosed external hemorrhoids presenting within 72 hours, excision provides faster pain relief and reduces recurrence risk 1

Failure of Conservative Management

Surgery becomes necessary when medical therapy and office-based procedures have been inadequate 1, 6:

• Persistent symptoms after 1-2 weeks of conservative treatment 1
• Failed rubber band ligation or other office procedures 1
• Symptom recurrence after flavonoid therapy (80% recurrence within 3-6 months after cessation) 1

Surgical Technique Selection

Conventional Excisional Hemorrhoidectomy

• Most effective overall treatment with lowest recurrence (2-10%) 1, 4
• Ferguson (closed) or Milligan-Morgan (open) techniques show comparable efficacy 4
• Major drawback: postoperative pain requiring narcotic analgesics, with 2-4 weeks before return to work 1, 4

Stapled Hemorrhoidopexy

• Produces significantly less postoperative pain than conventional hemorrhoidectomy 4
• Faster postoperative recovery 3
• Trade-off: higher recurrence rate compared to excisional techniques 3
• Appropriate for circular hemorrhoids 4

Techniques to Absolutely Avoid

• Anal dilatation should never be performed: 52% incontinence rate at 17-year follow-up with documented sphincter injuries 1, 4
• Simple incision and drainage of thrombosed hemorrhoids is contraindicated: leads to persistent bleeding and higher recurrence 1
• Cryotherapy should be avoided: causes prolonged pain, foul-smelling discharge, and requires more additional therapy 1, 4

Important Contraindications and Considerations

• Immunocompromised patients (uncontrolled AIDS, neutropenia, severe diabetes) have increased risk of necrotizing pelvic infection after procedures 1
• Postoperative complications include urinary retention, bleeding, anal stenosis, infection, and incontinence (sphincter defects in up to 12% of patients) 4
• Never assume all anorectal symptoms are hemorrhoids: anal fissures coexist in up to 20% of hemorrhoid patients 1
