Treatment for External Hemorrhoids
Begin with conservative management for all external hemorrhoids, including dietary fiber (25-30g daily), increased water intake, and avoidance of straining during defecation, regardless of severity or comorbidities. 1
Initial Conservative Management (First-Line for All Patients)
- Increase dietary fiber to 25-30 grams daily using bulk-forming agents like psyllium husk (5-6 teaspoonfuls with 600 mL water daily) to soften stool and reduce straining 1
- Ensure adequate water intake throughout the day to maintain soft, bulky stools 1
- Limit time on toilet to 3 minutes and avoid straining during defecation 1
- Take regular warm sitz baths to reduce inflammation and discomfort 1
Pharmacological Management for Symptomatic External Hemorrhoids
For symptomatic non-thrombosed external hemorrhoids, apply topical 0.3% nifedipine with 1.5% lidocaine ointment every 12 hours for two weeks, which achieves 92% resolution compared to 45.8% with lidocaine alone. 1
- This combination works by relaxing internal anal sphincter hypertonicity that contributes to pain, with no systemic side effects observed 1
- Flavonoids (phlebotonics) provide additional relief of bleeding, pain, and swelling through improved venous tone, though 80% symptom recurrence occurs within 3-6 months after cessation 1, 2
- Short-term topical corticosteroids (≤7 days maximum) may reduce local perianal inflammation, but never exceed 7 days due to risk of perianal tissue thinning 1
- Topical nitrates show good results but are limited by high incidence of headache (up to 50% of patients) 1
- Over-the-counter oral analgesics (acetaminophen or ibuprofen) for additional pain control 1
Management of Thrombosed External Hemorrhoids
Early Presentation (Within 72 Hours of Symptom Onset)
Complete surgical excision under local anesthesia is recommended for thrombosed external hemorrhoids presenting within 72 hours, providing faster pain relief and reduced recurrence risk compared to conservative management. 1, 2
- Perform complete excision of the entire thrombosed hemorrhoid, not simple incision and drainage, as drainage alone leads to persistent bleeding and significantly higher recurrence rates 1
- This can be performed safely as an outpatient procedure under local anesthesia with low complication rates 1
- Lidocaine injection into surrounding tissue provides adequate anesthesia for the procedure 3
Late Presentation (>72 Hours After Symptom Onset)
For patients presenting more than 72 hours after 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
- Prescribe stool softeners and oral analgesics 1, 2
- Use topical 5% lidocaine for symptomatic pain relief 2
- Continue sitz baths and dietary modifications 1
Special Considerations for Patients on Anticoagulation
- Attempt conservative management first regardless of anticoagulation status 1
- If surgical excision is necessary within 72 hours, assess coagulation status (PT/INR, aPTT) and consider temporary anticoagulation adjustment in consultation with the prescribing physician 1
- Check complete blood count, serum electrolytes, BUN, creatinine, and coagulation studies to assess bleeding severity 1
- Obtain blood type and crossmatch if hemoglobin is significantly low or patient shows signs of hemodynamic instability 1
Novel 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. 3
- 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 3
- Approximately 90% of patients were satisfied with the technique and would opt for the procedure again 3
- This represents a departure from traditional teaching that rubber band ligation should only be used for internal hemorrhoids above the dentate line 3
When to Refer for Surgical Evaluation
- Failure of conservative and topical management after 1-2 weeks of appropriate treatment 1, 4
- Recurrent thrombosis despite conservative management 4
- Mixed internal and external hemorrhoids requiring comprehensive surgical approach 1
- Concomitant anorectal conditions (fissure, fistula, abscess) requiring surgery 1
- Symptoms of severe pain, high fever, or urinary retention suggesting necrotizing pelvic sepsis (rare but serious complication) 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—complete excision is required if surgical intervention is chosen 1
- Never attribute significant bleeding or anemia to hemorrhoids without proper colonic evaluation; colonoscopy is required to rule out inflammatory bowel disease or colorectal cancer 1, 5
- Avoid anoscopy in awake patients with acute thrombosed hemorrhoids, as excruciating pain typically requires proper sedation 1
- Patients with portal hypertension or cirrhosis may have anorectal varices rather than true hemorrhoids; standard hemorrhoidectomy can cause life-threatening bleeding in this population 1, 5
Surgical Options for Refractory Cases
- Conventional excisional hemorrhoidectomy (Milligan-Morgan open or Ferguson closed technique) achieves 90-98% success rates with 2-10% recurrence for mixed internal/external hemorrhoids 1, 2
- Ferguson (closed) technique may offer slightly improved wound healing compared to open technique 1
- Expect postoperative pain requiring narcotic analgesics, with most patients not returning to work for 2-4 weeks 1
