What is the recommended treatment for an adult with grade I–II internal hemorrhoids?

Treatment for Grade I–II Internal Hemorrhoids

Start with dietary fiber supplementation (25–30 grams daily) plus increased water intake, and if symptoms persist after 1–2 weeks, proceed directly to rubber band ligation as the first-line procedural intervention. 1

Initial Conservative Management (First-Line for All Patients)

All patients with grade I–II internal hemorrhoids must begin with conservative therapy before considering procedural interventions. 1

Dietary and Lifestyle Modifications

• Increase dietary fiber to 25–30 grams daily using bulk-forming agents such as psyllium husk (5–6 teaspoons mixed with 600 mL water daily) to soften stool and reduce straining. 1, 2
• Ensure adequate water intake to prevent constipation and maintain soft, bulky stools. 1
• Avoid prolonged sitting and straining during defecation, as these worsen hemorrhoidal symptoms. 1
• Take regular sitz baths (warm water soaks) to reduce inflammation and discomfort. 1

Pharmacological Adjuncts

• Flavonoids (phlebotonics) can reduce bleeding, pain, and swelling through improvement of venous tone, but be aware that 80% of patients experience symptom recurrence within 3–6 months after stopping the medication. 1, 2, 3
• Topical lidocaine 1.5–2% provides symptomatic relief of local pain and itching. 1
• Topical corticosteroids (hydrocortisone 1%) may reduce perianal inflammation, but must be limited to ≤7 days maximum to avoid mucosal thinning. 1, 2, 4

Office-Based Procedural Treatment (When Conservative Management Fails)

If symptoms persist or worsen after 1–2 weeks of conservative therapy, proceed to office-based procedures. 1

Rubber Band Ligation (Preferred First-Line Procedure)

Rubber band ligation is the most effective office-based procedure for grade I–II internal hemorrhoids and should be the first procedural intervention. 1

Efficacy and Outcomes

• Success rates range from 70.5% to 89% depending on hemorrhoid grade and follow-up duration. 1
• Approximately 90% of patients remain asymptomatic at 1-year follow-up, with 69% remaining asymptomatic at 10–17 years. 1
• Rubber band ligation is more effective than sclerotherapy and requires fewer additional treatments than infrared photocoagulation. 1, 5

Technique

• The procedure can be performed in an office setting without anesthesia using commercially available suction devices. 1
• The band must be placed ≥2 cm proximal to the dentate line to avoid severe pain, as somatic sensory nerves are absent above this level. 1
• Up to 3 hemorrhoidal columns may be banded in a single session, though many practitioners prefer treating 1–2 columns at a time. 1

Complications

• Pain occurs in 5–60% of patients, typically mild and manageable with sitz baths and over-the-counter analgesics. 1
• Other complications (abscess, urinary retention, band slippage) occur in approximately 5% of patients. 1
• Severe bleeding may occur when the eschar sloughs, typically 1–2 weeks after treatment. 1
• Necrotizing pelvic sepsis is rare but serious, with increased risk in immunocompromised patients (uncontrolled AIDS, neutropenia, severe diabetes). 1

Alternative Office-Based Procedures (Less Preferred)

Injection Sclerotherapy

• Suitable for first- and second-degree hemorrhoids, using sclerosing agents to cause fibrosis and tissue shrinkage. 1
• Achieves 89.9% improvement or cure rate for grade I–II hemorrhoids, but has no proven superiority over conservative management alone. 1
• Less effective than rubber band ligation overall. 1

Infrared Photocoagulation

• Success rates of 67–96% for grade I–II hemorrhoids. 1, 5
• Requires more repeat treatments than rubber band ligation. 1

Bipolar Diathermy

• Success rates of 88–100% for bleeding control in grade II hemorrhoids. 1

Critical Diagnostic Considerations Before Treatment

Mandatory Evaluations

• Anoscopy should be performed when feasible to directly visualize hemorrhoids and exclude other anorectal pathology. 1
• Positive fecal occult blood tests should NOT be attributed to hemorrhoids until the colon is adequately evaluated by colonoscopy. 1
• Anemia attributable solely to hemorrhoids is rare (approximately 0.5 cases per 100,000 population); colonoscopy is necessary to exclude inflammatory bowel disease or colorectal cancer. 1
• Persistent anal pain is generally NOT caused by uncomplicated internal hemorrhoids and suggests alternative diagnoses such as anal fissure, abscess, or thrombosis. 1
• Colonoscopy is recommended for patients aged ≥50 years or those with colorectal cancer risk factors before initiating hemorrhoid-specific treatment. 1

When to Escalate to Surgical Management

Surgical hemorrhoidectomy is NOT typically indicated for grade I–II hemorrhoids unless there is:

• Failure of both medical and office-based therapy 1
• Mixed internal and external hemorrhoids 1
• Concomitant conditions (fissure, fistula) requiring surgery 1
• Active bleeding causing anemia 1

Critical Pitfalls to Avoid

• Never use topical corticosteroids for more than 7 days, as prolonged use causes mucosal thinning and increases injury risk. 1, 2, 4
• Never attribute anemia or chronic bleeding to hemorrhoids without colonoscopic assessment, especially in older adults. 1
• Never perform rubber band ligation in immunocompromised patients (uncontrolled HIV/AIDS, severe neutropenia, poorly controlled diabetes) due to heightened risk of necrotizing pelvic infection. 1
• Avoid anal dilatation entirely, as it causes sphincter injuries and results in 52% incontinence rate at long-term follow-up. 1
• Avoid cryotherapy, as it causes prolonged pain, foul-smelling discharge, and requires more additional therapy. 1
• Do not rely on over-the-counter topical preparations as primary treatment, as they lack strong evidence for reducing hemorrhoidal swelling, bleeding, or protrusion. 1

Follow-Up and Reassessment

• If symptoms worsen or fail to improve within 1–2 weeks of conservative treatment, or if there is significant bleeding, severe pain, or fever, further evaluation is necessary. 1
• Repeated rubber band ligation may be needed in up to 20% of patients. 3
• If office-based procedures fail, consider referral for surgical hemorrhoidectomy. 1
