Treatment for External Hemorrhoids
Begin with conservative management for all external hemorrhoids, including dietary modifications and topical treatments; reserve surgical excision exclusively for thrombosed external hemorrhoids presenting within 72 hours of symptom onset. 1
Initial Conservative Management (First-Line for All External Hemorrhoids)
All external hemorrhoids should start with conservative therapy regardless of severity or presentation timing 1:
- Increase dietary fiber to 25-30 grams daily (achievable with 5-6 teaspoonfuls of psyllium husk mixed with 600 mL water daily) to soften stool and reduce straining 1
- Increase water intake to maintain soft, bulky stools 1
- Avoid straining during defecation, as this is the primary trigger for symptom exacerbation 1
- Warm sitz baths reduce inflammation and provide symptomatic relief 1
Topical Pharmacological Management
For symptomatic relief, apply topical agents in the following priority:
Most Effective: Nifedipine-Lidocaine Combination
- Topical 0.3% nifedipine with 1.5% lidocaine ointment applied every 12 hours for two weeks achieves 92% resolution rate compared to only 45.8% with lidocaine alone 1
- This works by relaxing internal anal sphincter hypertonicity that contributes to pain 1
- No systemic side effects have been observed with topical nifedipine 1
Alternative Topical Options
- Lidocaine 1.5-2% ointment or cream provides symptomatic relief of local pain and itching 1
- Topical corticosteroids may reduce local perianal inflammation but MUST be limited to ≤7 days maximum to avoid thinning of perianal and anal mucosa 1
- Topical nitrates show good results but are limited by high incidence of headache (up to 50% of patients) 1
- Topical heparin significantly improves healing, though evidence is limited to small studies 1
Oral Adjunctive Therapy
- Flavonoids (phlebotonics) relieve bleeding, pain, and swelling through improvement of venous tone, but have 80% symptom recurrence within 3-6 months after cessation 1, 2
- Over-the-counter oral analgesics (acetaminophen or ibuprofen) for additional pain control 1
Management of Thrombosed External Hemorrhoids
The timing of presentation determines the treatment approach:
Early Presentation (Within 72 Hours of Symptom Onset)
Complete surgical excision under local anesthesia is recommended, providing faster pain relief and reduced risk of recurrence compared to conservative management 1, 2:
- This can be performed as an outpatient procedure with low complication rates 1
- Never perform simple incision and drainage—this leads to persistent bleeding and significantly higher recurrence rates 1, 3
- Complete excision removes the entire thrombosed hemorrhoid, not just the clot 1
Late Presentation (>72 Hours After Symptom Onset)
Conservative management is preferred as natural resolution has typically begun 1, 2:
- Apply topical 0.3% nifedipine with 1.5% lidocaine ointment every 12 hours for two weeks 1
- Use stool softeners and oral/topical analgesics 1
- The condition is usually self-limiting and subsides within a few days to a week 4
Special Considerations for Patients on Anticoagulants or with Bleeding Disorders
- Attempt conservative management first regardless of anticoagulation status 1
- If surgical excision is necessary within 72 hours, assess coagulation status (PT/INR, aPTT, platelet count) and consider temporary anticoagulation adjustment in consultation with the prescribing physician 1
- Check vital signs, complete blood count, and coagulation studies if significant bleeding is present 3
- Blood typing and cross-matching should be performed for severe bleeding 3
When to Refer for Surgical Evaluation
Refer to a colorectal surgeon when 5:
- Recurrent thrombosis or persistent symptoms despite adequate conservative management
- Mixed internal and external hemorrhoids with symptomatic external component failing conservative therapy
- Symptoms worsen or fail to improve within 1-2 weeks of conservative treatment 1
- Concomitant anorectal conditions requiring surgery (fissure, fistula, abscess) 5
Critical Pitfalls to Avoid
- Never use corticosteroid creams for more than 7 days—prolonged use causes thinning of perianal and anal mucosa, increasing risk of injury 1, 3
- Never perform simple incision and drainage of thrombosed external hemorrhoids—complete excision is required if surgical intervention is chosen 1, 3
- Do not attribute anemia or positive fecal occult blood to hemorrhoids until the colon is adequately evaluated with colonoscopy 1
- Avoid rubber band ligation for external hemorrhoids in standard practice, as external hemorrhoids below the dentate line are highly innervated by somatic pain receptors, making this procedure extremely painful 6, 7 (Note: While one recent case series 6 suggests rubber band ligation with local anesthesia may be feasible for non-thrombosed external hemorrhoids, this remains experimental and is not recommended in established guidelines 1)
- Rule out anorectal varices in patients with portal hypertension or cirrhosis, as standard hemorrhoidectomy can cause life-threatening bleeding in this population 1
Follow-Up and Monitoring
- If symptoms persist beyond 2 weeks despite conservative management, further evaluation is necessary 3
- Monitor for signs of infection (fever, increasing pain, purulent discharge) which may require antibiotics 3
- Immunocompromised patients require closer monitoring due to increased risk of severe infection 3
