Hemorrhoids: Classification & Treatment

Anatomy & Classification

Internal Hemorrhoid Grading (above the dentate line - painless)

External Hemorrhoids (below the dentate line - painful)

• Present with acute onset of pain and swelling
• Pain peaks in the first 48 hours then gradually subsides
• Can thrombose, forming a firm, tender perianal lump

Step-by-Step Treatment Approach

1. Conservative (First-Line for All Grades)

• Dietary fiber - 25-35 g/day (psyllium, methylcellulose); reduces persistent symptoms by up to 53%
• Adequate fluid intake - 6-8 glasses of water per day
• Avoid straining and prolonged sitting on the toilet
• Sitz baths - warm water soaks for 10-15 minutes, 2-3x/day for comfort
• Stool softeners (docusate) if needed
• Topical agents - hydrocortisone creams, lidocaine, or witch hazel for symptom relief (itching, pain); do not resolve the underlying hemorrhoid

2. Office-Based Procedures (Grade I-III)

a) Rubber Band Ligation (RBL) - Most Effective Office Procedure

• A ligating device is passed through an anoscope; hemorrhoid tissue is drawn into the cylinder and two rubber bands are released at its base
• Causes ischemic necrosis; tissue sloughs over several days
• Effective in >80% of Grade I-III internal hemorrhoids
• Can band only one site per visit to reduce risk
• Complications: pain, bleeding (up to 1-2 weeks post-procedure), rare pelvic sepsis

b) Sclerotherapy

• Injection of 1-5 mL of 5% phenol in oil (most common) or hypertonic saline into the submucosa at the apex of the hemorrhoid column via anoscope
• Do NOT inject directly into the hemorrhoid - risk of thrombosis
• Best for Grade I-II hemorrhoids, or those too small to band
• More complications than RBL long-term

c) Infrared Coagulation (IRC)

• Infrared light applied 3-5 times at the hemorrhoid base through anoscope (1.5 sec each burst)
• Effective for Grade I-II internal hemorrhoids
• As effective as sclerotherapy; may need multiple sessions
• Advantages: minimal pain, fast recovery

d) Hemorrhoid Artery Ligation (HAL) / Doppler-Guided HAL + Mucopexy

• Uses Doppler to identify and ligate terminal hemorrhoidal arteries
• Can be combined with mucopexy (plication of prolapsing tissue)
• Effective for Grade II-III; less postoperative pain than hemorrhoidectomy

3. Surgical Treatment (Grade III-IV or Failed Office Procedures)

a) Excisional Hemorrhoidectomy - Gold Standard

• Most definitive treatment; performed as outpatient under MAC + local or spinal anesthesia
• Patient placed in prone jack-knife position
• Hemorrhoidal tissue dissected off the internal anal sphincter; wound may be left open or closed with absorbable suture
• Must leave ≥2 cm of normal anoderm between excision sites to prevent anal stenosis
• Must preserve the internal anal sphincter
• Post-op: multimodal analgesia (acetaminophen + NSAIDs + minimal opioids ± gabapentin); limit IV fluids to <700 mL to reduce urinary retention (~15% incidence)
• Limitation: significant postoperative pain

b) Stapled Hemorrhoidopexy (PPH - Procedure for Prolapse and Hemorrhoids)

• Excises a circumferential sleeve of mucosa/submucosa, interrupting hemorrhoidal vessels and pulling up prolapsed tissue
• Less postoperative pain than excisional hemorrhoidectomy
• Enthusiasm has waned due to rare but severe complications: rectovaginal fistula, chronic debilitating pain, pelvic sepsis
• Long-term recurrence rates similar to excisional hemorrhoidectomy

4. Special Situations

Thrombosed External Hemorrhoids

• If patient presents within 48-72 hours of onset, early surgical excision is beneficial (pain relief is dramatic)
• After 72 hours, pain is usually subsiding - conservative management preferred (sitz baths, stool softeners, topical agents)
• Excision: elliptical incision under local anesthesia, clot removed, wound usually left open

Hemorrhoids in Pregnancy

• Conservative management is mainstay (fiber, fluids, sitz baths, topical agents)
• Office procedures can be considered in refractory cases; surgery deferred until postpartum if possible
• Many hemorrhoids regress after delivery

Anticoagulated Patients

• Monitor closely - hemorrhoidal bleeding rarely leads to anemia but is of increased concern
• Office procedures can be used cautiously; post-banding bleeding risk is higher

Treatment Algorithm Summary

Symptomatic Hemorrhoids
        |
        ↓
Conservative (all grades): fiber, fluids, sitz baths, topical agents
        |
        ├── Grade I-II (+ selected III): Office procedures
        │         → RBL (most effective) > IRC > Sclerotherapy > HAL
        |
        └── Grade III-IV or failed office Rx: Surgery
                  → Excisional hemorrhoidectomy (gold standard)
                  → Stapled hemorrhoidopexy (selected cases, with caution)
                  
Special: Thrombosed external hemorrhoid <72h → Excision
