Treatment of External Hemorrhoids
For external hemorrhoids, begin with conservative management including increased fiber (25-30g daily) and water intake, combined with topical 0.3% nifedipine plus 1.5% lidocaine ointment every 12 hours for two weeks, which achieves 92% resolution. 1
Initial Conservative Management (First-Line for All External Hemorrhoids)
All external hemorrhoids should start with conservative therapy regardless of severity 1:
- Increase dietary fiber to 25-30 grams daily using bulk-forming agents like psyllium husk (5-6 teaspoonfuls with 600 mL water daily) 1
- Adequate water intake to soften stool and reduce straining 1
- Avoid straining during defecation through relaxation techniques and dietary adjustments 1
- Sitz baths (warm water soaks) reduce inflammation and discomfort 1
Pharmacological Management for Symptomatic External Hemorrhoids
Most Effective Topical Treatment
- 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 Agents
- Topical lidocaine (1.5-2% ointment) 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 Medications
- 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 treatment approach depends critically on timing of presentation 1, 3:
Early Presentation (Within 72 Hours of Symptom Onset)
- Complete surgical excision under local anesthesia is the preferred treatment 1, 3, 2
- This provides faster symptom resolution and lower recurrence rates compared to conservative management 1, 3
- Can be performed as an outpatient procedure with low complication rates 1
Late Presentation (>72 Hours After Symptom Onset)
- Conservative management is preferred as the natural resolution process has begun 1, 3
- Use topical 0.3% nifedipine with 1.5% lidocaine ointment every 12 hours for two weeks 1, 3
- Add stool softeners and oral analgesics 1, 3
- Topical muscle relaxants can provide additional pain relief 1, 3
Emerging Treatment Option: Rubber Band Ligation for External Hemorrhoids
Recent evidence suggests rubber band ligation combined with local anesthesia injection may be an alternative to hemorrhoidectomy for symptomatic non-thrombosed external hemorrhoids 4:
- Lidocaine is injected into surrounding tissue to anesthetize the hemorrhoid prior to band application 4
- In a cohort of 50 patients: 50% reported no post-procedure discomfort, 44% had mild pain managed with OTC analgesics, and only 6% experienced moderate-severe pain that resolved within a week 4
- Approximately 90% patient satisfaction with willingness to repeat the procedure 4
This represents a departure from traditional teaching that rubber band ligation should only be used for internal hemorrhoids 1, though this is based on a single small study and requires further validation.
Surgical Management
Surgical hemorrhoidectomy is indicated for 1:
- Failure of medical and conservative therapy
- Mixed internal and external hemorrhoids
- Concomitant anorectal conditions requiring surgery (fissure, fistula)
- Patient preference after thorough discussion
Conventional excisional hemorrhoidectomy (Milligan-Morgan or Ferguson technique) achieves low recurrence rates (2-10%) but requires 2-4 weeks recovery and narcotic analgesics for postoperative pain 1
Critical Pitfalls to Avoid
- Never use corticosteroid creams for more than 7 days as prolonged use causes thinning of perianal and anal mucosa, increasing risk of injury 1
- Never perform simple incision and drainage of thrombosed external hemorrhoids—this leads to persistent bleeding and higher recurrence rates; complete excision is required if surgical intervention is chosen 1, 3, 2
- Never attribute significant bleeding or anemia to hemorrhoids without proper colonic evaluation including colonoscopy to rule out inflammatory bowel disease or colorectal cancer 1
- Avoid assuming all anorectal symptoms are due to hemorrhoids as other conditions like anal fissures may coexist in up to 20% of patients 1
When to Reassess or Escalate Care
- If symptoms worsen or fail to improve within 1-2 weeks of conservative treatment, reassessment is recommended 1, 3
- Presence of severe pain, high fever, and urinary retention suggests necrotizing pelvic sepsis (rare but serious complication) requiring emergency evaluation 1
- Anoscopy should be performed when feasible and well tolerated to rule out other causes of anorectal symptoms 1, 3
