Treatment of Grade 4 External Hemorrhoids
Grade 4 external hemorrhoids require surgical excisional hemorrhoidectomy as the definitive treatment, with either the open Milligan-Morgan or closed Ferguson technique being the gold standard approach. 1, 2
Clarification on Terminology
It's important to note that "grade 4 external hemorrhoids" is technically a misnomer—the grading system (I-IV) applies specifically to internal hemorrhoids based on their degree of prolapse. 1 External hemorrhoids are not graded in this manner and typically only cause symptoms when thrombosed. 1 However, if you're referring to grade 4 internal hemorrhoids (irreducible prolapse) with external components (mixed hemorrhoidal disease), the following treatment algorithm applies:
Surgical Management (Primary Treatment)
Conventional excisional hemorrhoidectomy is indicated for grade 4 hemorrhoids and represents the most effective treatment with the lowest recurrence rate of 2-10%. 1, 2, 3
Surgical Technique Options:
Open hemorrhoidectomy (Milligan-Morgan): Excises internal and external hemorrhoid components while leaving wounds open in a 3-leaf clover pattern, healing secondarily over 4-8 weeks 2
Closed hemorrhoidectomy (Ferguson): Excises hemorrhoid components and closes wounds primarily, associated with comparable outcomes to open technique 1, 2
Stapled hemorrhoidopexy: Alternative option with faster postoperative recovery but higher recurrence rates compared to conventional hemorrhoidectomy 4, 3
Important Surgical Considerations:
- Narcotic analgesics are generally required for postoperative pain management 1, 2
- Most patients cannot return to work for 2-4 weeks following surgery 1, 2
- Postoperative complications occur in approximately 10% of cases, including bleeding, urinary retention, anal stenosis, and infection 2, 5
Techniques to Avoid
Anal dilatation should never be performed due to a 52% incontinence rate at 17-year follow-up and sphincter injuries 1, 2
Cryotherapy should be avoided due to prolonged pain, foul-smelling discharge, and greater need for additional therapy 1
Simple incision and drainage is not recommended due to persistent bleeding and higher recurrence rates 1
Non-Surgical Options Are Inadequate
Office-based procedures like rubber band ligation are NOT appropriate for grade 4 hemorrhoids, as they are indicated only for grades 1-3 internal hemorrhoids. 1, 3 Grade 4 disease exceeds the threshold for conservative or office-based management. 1
Preoperative Conservative Measures
While awaiting surgery, symptomatic relief can be achieved with:
- Increased dietary fiber and water intake to soften stool and reduce straining 1, 6
- Topical 0.3% nifedipine with 1.5% lidocaine ointment applied every 12 hours for pain relief 1, 6
- Short-term topical corticosteroids (≤7 days only) to reduce inflammation 1, 6
- Sitz baths for symptomatic relief 1, 6
Critical Pitfalls to Avoid
- Do not delay definitive surgical treatment for grade 4 hemorrhoids, as conservative measures will fail 1, 3
- Never attribute significant bleeding or anemia to hemorrhoids without proper colonoscopic evaluation to rule out proximal colonic pathology 1
- Avoid long-term corticosteroid use (>7 days) due to risk of perianal tissue thinning 1, 6
