What is the recommended management for symptomatic internal hemorrhoids, including conservative measures and indications for procedural or surgical treatment?

Hemorrhoid Treatment

Begin with conservative management for all symptomatic internal hemorrhoids, escalating to rubber band ligation for persistent grade I-III disease, and reserve surgical hemorrhoidectomy for grade III-IV hemorrhoids that fail office procedures or present with complications. 1

Initial Conservative Management (First-Line for All Grades)

All patients with symptomatic hemorrhoids should start with conservative therapy regardless of severity 1, 2:

• Increase dietary fiber to 25-30 grams daily, achievable with 5-6 teaspoonfuls of psyllium husk mixed with 600 mL water 1, 3
• Ensure adequate hydration throughout the day to soften stool and reduce straining 1, 2
• Avoid straining during defecation—this is the single most important behavioral modification 1, 3
• Take regular sitz baths (warm water soaks) to reduce inflammation and discomfort 1, 2

Topical Pharmacological Therapy

For symptomatic relief during conservative management:

• Topical 0.3% nifedipine with 1.5% lidocaine ointment applied every 12 hours for two weeks achieves 92% resolution rate (compared to 45.8% with lidocaine alone) 1, 2
• Topical corticosteroids may reduce perianal inflammation but must be limited to ≤7 days maximum to avoid thinning of anal and perianal mucosa 1, 2, 3
• Flavonoids (phlebotonics) relieve bleeding, pain, and swelling, though 80% symptom recurrence occurs within 3-6 months after cessation 1, 3

Office-Based Procedures (Second-Line)

When conservative management fails after 4-8 weeks, proceed to office-based procedures for grade I-III internal hemorrhoids:

Rubber Band Ligation (Preferred First Procedural Intervention)

Rubber band ligation is the most effective office-based procedure with success rates of 70.5-89% depending on hemorrhoid grade 1, 4:

• Place bands at least 2 cm proximal to the dentate line to avoid severe pain, as somatic sensory nerves are absent above the anal transition zone 1
• Treat 1-2 hemorrhoid columns per session (up to 3 can be banded, but limiting to 1-2 reduces complications) 1
• More effective than sclerotherapy and requires fewer repeat treatments than infrared photocoagulation 1, 4

Contraindications to rubber band ligation:

• Immunocompromised patients (uncontrolled AIDS, neutropenia, severe diabetes) have increased risk of necrotizing pelvic infection 1
• Thrombosed or acutely prolapsed hemorrhoids 2

Alternative Office Procedures

• Injection sclerotherapy is suitable for grade I-II hemorrhoids, using sclerosing agents to cause fibrosis and tissue shrinkage 1
• Infrared photocoagulation has 67-96% success rates for grade I-II hemorrhoids but requires more repeat treatments 1
• Bipolar diathermy achieves 88-100% bleeding control in grade II hemorrhoids 1

Surgical Management (Third-Line)

Indications for Hemorrhoidectomy

Surgical hemorrhoidectomy is indicated for: 1, 2

• Failure of medical and office-based therapy
• Symptomatic grade III-IV hemorrhoids
• Mixed internal and external hemorrhoids
• Concomitant anorectal conditions (fissure, fistula) requiring surgery
• Anemia from hemorrhoidal bleeding

Surgical Techniques

Conventional excisional hemorrhoidectomy (Milligan-Morgan open or Ferguson closed technique) is the most effective treatment with 2-10% recurrence rate 1, 4:

• Ferguson (closed) technique may offer slightly improved wound healing compared to open technique 1
• Major drawback is postoperative pain requiring narcotic analgesics, with most patients not returning to work for 2-4 weeks 1
• Complications include: urinary retention (2-36%), bleeding (0.03-6%), anal stenosis (0-6%), infection (0.5-5.5%), and incontinence (2-12%) 1

Stapled hemorrhoidopexy shows promising results with less postoperative pain and faster recovery, but lacks long-term follow-up data and carries risk of rare severe complications (rectal perforation, pelvic sepsis) 1, 4

Management of Thrombosed External Hemorrhoids

Early Presentation (≤72 Hours)

Complete surgical excision under local anesthesia is recommended for thrombosed external hemorrhoids presenting within 72 hours, providing faster pain relief and lower recurrence rates 1, 2:

• Excise the entire thrombosed hemorrhoid in one piece under local anesthesia as an outpatient procedure 1
• Leave the wound open to heal by secondary intention 1

Late Presentation (>72 Hours)

Conservative management is preferred when presentation exceeds 72 hours, as natural resolution has typically begun 1, 2:

• Topical 0.3% nifedipine with 1.5% lidocaine ointment every 12 hours for two weeks 1, 2
• Stool softeners and oral analgesics 1
• Sitz baths 2

Critical Pitfalls to Avoid

• Never perform simple incision and drainage of thrombosed hemorrhoids—this leads to persistent bleeding and higher recurrence rates; complete excision is required 1, 2, 3
• Never use corticosteroid creams for more than 7 days—prolonged use causes thinning of perianal and anal mucosa 1, 2, 3
• Never attribute anemia or significant bleeding to hemorrhoids without colonoscopy, especially in patients over 50 years or with risk factors for colorectal cancer 1, 2
• Avoid anal dilatation entirely—this outdated technique causes sphincter injuries with 52% incontinence rate at 17-year follow-up 1, 3
• Avoid cryotherapy—rarely used due to prolonged pain, foul-smelling discharge, and greater need for additional therapy 1

Special Populations

Pregnant Patients

Safe treatments during pregnancy include 1:

• Dietary fiber and adequate fluid intake
• Bulk-forming agents (psyllium husk)
• Osmotic laxatives (polyethylene glycol, lactulose)
• Hydrocortisone foam in third trimester (no adverse events vs. placebo)

Patients with Portal Hypertension

Patients with cirrhosis or portal hypertension may have anorectal varices rather than true hemorrhoids—standard hemorrhoidectomy can cause life-threatening bleeding in this population 1, 3

When to Reassess or Escalate Care

• If symptoms worsen or fail to improve within 1-2 weeks of conservative treatment, reassessment is required 1
• Severe pain, high fever, or urinary retention suggests necrotizing pelvic sepsis (rare but serious complication) requiring emergency evaluation 1
• Significant bleeding with hemodynamic instability requires immediate evaluation, complete blood count, and consideration of blood transfusion 1
