Treatment of Hemorrhoids

Classification (Grades of Internal Hemorrhoids)

1. Conservative (Medical) Management

• Dietary fiber and fluids - the primary noninvasive treatment. Systematic review evidence shows that persistent hemorrhoid symptoms decreased by 53% in patients receiving dietary fiber supplementation. Targets are increased bulk (psyllium, bran, fiber supplements) and adequate water intake. This also reduces recurrence after procedures.
• Sitz baths - warm water soaks for symptomatic relief.
• Stool softeners - reduce straining and trauma.
• Topical preparations - suppositories and topical anesthetics for symptom relief; limited curative effect.
• Activity modification - avoidance of prolonged straining and constipation.

2. Office-Based Procedures (Grade I, II, selected Grade III)

Rubber Band Ligation (RBL) - Most Effective Office Procedure

• A tiny rubber band (internal diameter ~1 mm) is placed around redundant rectal mucosa, well above the dentate line.
• Banded tissue undergoes ischemic necrosis and sloughs in 7-14 days.
• Produces a "pexy" effect, anchoring the prolapsing tissue, plus reduces blood supply.
• Repeat at 3-4 week intervals until symptoms are controlled.
• Only one site treated per visit.
• Contraindicated in patients on anticoagulants (unless discontinued beforehand) due to post-procedure bleeding risk.
• Highly effective for Grade I, II, and some Grade III internal hemorrhoids.

Injection Sclerotherapy

• Used for Grade I and II hemorrhoids.
• Sclerosant (5% phenol or saline) is injected at the base of the hemorrhoid, 1-2 mL, under anoscopic guidance.
• Systematic review evidence shows sclerotherapy has uncertain effectiveness compared to banding.
• More late complications reported than with banding.

Infrared Coagulation (IRC)

• Applied to the base of internal hemorrhoids; coagulates the vessels.
• Evidence shows it is likely beneficial and approximately as effective as rubber band ligation for lower-grade hemorrhoids.
• Generally less discomfort than banding.

Other Office Techniques

• Radiofrequency coagulation, cryotherapy, and direct-current (Ultroid) therapy are less commonly used.

• Bleeding diathesis / uncontrolled anticoagulation
• Pregnancy or immediately postpartum (<8 weeks)
• Inflammatory bowel disease
• Anorectal fissures or active infections
• Immunodeficiency (HIV/AIDS)
• Portal hypertension (relative)

3. Surgical Treatment (Grade III refractory, Grade IV)

Excisional Hemorrhoidectomy

• The gold standard surgical approach, usually outpatient.
• Can be performed with conventional excision or energy-sealing devices (comparable results, potentially less recurrence).
• Higher symptom resolution rates than conservative therapy (OR 2.96, 95% CI 1.66-5.28) per a 2025 meta-analysis.

Doppler-Guided Hemorrhoidal Artery Ligation (DGHAL)

• Lower recurrence than single-session rubber band ligation.
• Typically performed in the operating room; more pain than office banding.
• Recurrence rates of 3-60% reported (wide variation).

Stapled Hemorrhoidopexy (PPH)

• Resects a ring of rectal mucosa above the hemorrhoids using a circular stapler.
• Largely fallen out of favor due to higher recurrence rates and risk of serious complications: chronic pain, rectovaginal fistula, staple-line bleeding.

4. External Hemorrhoids

• Present with acute-onset perianal pain and a purplish nodule.
• If presenting within 72 hours of onset: office excision (not just incision) under local anesthesia - superior to conservative therapy for faster relief and lower recurrence.
• If presenting >72 hours or improving: conservative management (avoid constipation, analgesics, ice/sitz baths) - pain typically peaks at 48-72 hours and resolves spontaneously over 7-10 days.
• Excision is preferred over simple incision because incision may miss multiple clots and leads to higher recurrence.
• Circumferential thrombosis or large/complex cases require urgent colorectal surgery referral.

5. Post-Procedure Care and Complications

• Mild aching for 1-2 days after banding is expected; patients should report fever, dysuria, inability to urinate (signs of perineal sepsis), or increasing pain.
• Follow-up at 4-6 weeks for reassessment and further banding if needed.
• Perineal/pelvic sepsis - rare but serious; requires hospitalization, broad-spectrum antibiotics, and debridement.
• Post-banding bleeding can occur up to 1-2 weeks; significant bleeding is uncommon but possible.

Key Evidence Update (2025 Meta-Analysis)

• Surgery achieves higher complete symptom resolution (OR 2.96, p<0.001).
• Pain advantage of surgery is clear within 4 days but equalizes beyond 10 days.
• Surgery shortens recovery in thrombosed external hemorrhoid cases by ~7 days.
• Recurrence is lower with surgery (no significant difference in post-op bleeding or urinary retention).
• Conclusion: individualize treatment based on symptom severity, patient preference, and risk tolerance.

Practical Summary by Grade

Important: Rectal bleeding should never be attributed to hemorrhoids alone without ruling out more proximal pathology. Flexible sigmoidoscopy or colonoscopy is warranted in patients >40-45 years, those with a colorectal cancer risk history, or when bleeding persists after adequate treatment.
