What is the appropriate management for hemorrhoids?

Management of Hemorrhoids

Begin with conservative management for all hemorrhoid grades—increased fiber (25-30g daily), adequate water intake, and avoidance of straining—as first-line therapy, then escalate to office-based procedures (rubber band ligation for grades I-III) or surgical hemorrhoidectomy (for grades III-IV or failed conservative therapy). 1, 2

Initial Assessment and Classification

Perform anoscopy during physical examination when feasible to visualize internal hemorrhoids and rule out other anorectal pathology. 3, 1 Digital rectal examination should assess for masses, fissures, or other conditions that may mimic hemorrhoidal symptoms. 1

Key Diagnostic Considerations

• Internal hemorrhoids are graded I-IV based on prolapse: grade I (bleeding only, no prolapse), grade II (prolapse with spontaneous reduction), grade III (require manual reduction), and grade IV (irreducible). 2, 4
• External hemorrhoids typically cause symptoms only when thrombosed, presenting with acute pain and a palpable perianal mass. 2, 4
• Check vital signs, hemoglobin, hematocrit, and coagulation parameters if significant bleeding or anemia is present. 1

Critical Red Flags Requiring Further Workup

• Never attribute fecal occult blood or anemia to hemorrhoids without colonoscopy—hemorrhoids alone do not cause positive guaiac tests, and anemia from hemorrhoids is rare (0.5 per 100,000 population). 2
• Perform colonoscopy if there is concern for inflammatory bowel disease or colorectal cancer based on patient history, family history, or atypical bleeding patterns. 3, 1
• Anal pain is not typical of uncomplicated internal hemorrhoids—its presence suggests anal fissure (occurs in up to 20% of hemorrhoid patients), abscess, or thrombosis. 2
• Consider imaging (CT, MRI, or endoanal ultrasound) only if suspicion exists for concomitant anorectal abscess, inflammatory bowel disease, or neoplasm. 3

Conservative Management (First-Line for All Grades)

All patients should begin with dietary and lifestyle modifications regardless of hemorrhoid grade or severity. 3, 1, 2

Dietary and Lifestyle Modifications

• Increase dietary fiber to 25-30 grams daily—this can be achieved with 5-6 teaspoonfuls of psyllium husk mixed with 600 mL water daily. 1, 2
• Ensure adequate water intake to soften stool and reduce straining during defecation. 3, 1, 2
• Avoid prolonged straining and sitting on the toilet—use proper bathroom habits. 3, 1
• Regular sitz baths (warm water soaks) reduce inflammation and discomfort. 2

Pharmacological Management

• Flavonoids (phlebotonics) relieve bleeding, pain, and swelling by improving venous tone, but symptom recurrence reaches 80% within 3-6 months after cessation. 3, 1, 2, 4
• Topical corticosteroids may reduce local perianal inflammation but must be limited to ≤7 days maximum to avoid thinning of perianal and anal mucosa. 1, 2
• Topical analgesics (lidocaine 1.5-2% ointment) provide symptomatic relief of local pain and itching. 1, 2
• Stool softeners and osmotic laxatives (polyethylene glycol, lactulose) help maintain soft stools. 2, 5

Management of Thrombosed External Hemorrhoids

Early Presentation (Within 72 Hours of Symptom Onset)

Perform complete surgical excision under local anesthesia as an outpatient procedure—this provides faster pain relief and significantly lower recurrence rates compared to conservative management. 1, 2, 4, 6

• The 72-hour window is critical—surgical benefit declines substantially after this timeframe. 1, 2
• Never perform simple incision and drainage—this leads to persistent bleeding and markedly higher recurrence rates; complete excision of the entire thrombosed hemorrhoid is required. 3, 1, 2

Late Presentation (Beyond 72 Hours)

Conservative management is preferred once natural resolution has begun. 2, 4, 6

• Topical 0.3% nifedipine with 1.5% lidocaine ointment applied every 12 hours for two weeks achieves 92% resolution rate compared to 45.8% with lidocaine alone. 1, 2
• Nifedipine relaxes internal anal sphincter hypertonicity without systemic side effects, unlike topical nitrates which cause headache in up to 50% of patients. 1, 2
• Continue stool softeners, oral analgesics (NSAIDs or acetaminophen), and sitz baths. 2, 4

Office-Based Procedures for Persistent Internal Hemorrhoids (Grades I-III)

Rubber band ligation is the most effective office-based procedure and should be the first procedural intervention when conservative management fails. 1, 2, 4

Rubber Band Ligation

• Success rates range from 70.5% to 89% depending on hemorrhoid grade and follow-up duration. 1, 2
• More effective than sclerotherapy and requires fewer repeat treatments than infrared photocoagulation. 1, 2
• The band must be placed at least 2 cm proximal to the dentate line to avoid severe pain—somatic sensory nerves are absent above the anal transition zone. 1
• Up to 3 hemorrhoid columns can be banded in a single session, though many practitioners limit treatment to 1-2 columns at a time. 1
• Pain (5-60% of patients) is the most common complication but is typically manageable with sitz baths and over-the-counter analgesics. 1
• Contraindicated in immunocompromised patients (uncontrolled AIDS, neutropenia, severe diabetes) due to increased risk of necrotizing pelvic sepsis. 1

Alternative Office-Based Procedures

• Sclerotherapy is suitable for grades I-II hemorrhoids, with 70-85% short-term efficacy but only one-third achieve long-term remission. 2, 4
• Infrared photocoagulation has 67-96% success rates for grades I-II hemorrhoids but requires more repeat treatments. 2, 4
• Bipolar diathermy achieves 88-100% bleeding control in grade II hemorrhoids. 2

Surgical Management

Conventional excisional hemorrhoidectomy is indicated for failure of medical and office-based therapy, symptomatic grade III-IV hemorrhoids, mixed internal and external hemorrhoids, or when concomitant anorectal conditions require surgery. 1, 2, 4

Indications for Hemorrhoidectomy

• Grades III-IV internal hemorrhoids with persistent symptoms despite conservative and office-based treatments. 1, 2, 4
• Mixed internal and external hemorrhoids with symptomatic external component. 2
• Acutely prolapsed, incarcerated, and thrombosed hemorrhoids. 2, 7
• Anemia from hemorrhoidal bleeding—this represents a critical threshold demanding definitive surgical intervention. 2
• Concomitant anorectal conditions (fissure, fistula) requiring surgery. 2

Surgical Technique and Outcomes

• Conventional excisional hemorrhoidectomy (Milligan-Morgan open or Ferguson closed technique) achieves 90-98% success rates with recurrence rates of only 2-10%. 1, 2, 4
• Ferguson (closed) technique may offer slightly improved wound healing compared to open technique, with comparable efficacy. 2
• Major drawback is postoperative pain requiring narcotic analgesics, with most patients not returning to work for 2-4 weeks. 2
• Complications include urinary retention (2-36%), bleeding (0.03-6%), anal stenosis (0-6%), infection (0.5-5.5%), and incontinence (2-12%). 2

Procedures to Avoid

• Never perform anal dilatation—it causes sphincter injuries and results in 52% incontinence rate at 17-year follow-up. 1, 2
• Avoid cryotherapy—it causes prolonged pain, foul-smelling discharge, and requires more additional therapy. 1, 2
• Stapled hemorrhoidopexy shows promising results but lacks long-term follow-up data and has reported complications including rectal perforation and pelvic sepsis. 2

Special Populations: Hemorrhoids in Pregnancy

Conservative management is the cornerstone throughout pregnancy—increase fiber to 30g daily, ensure adequate fluid intake, and use bulk-forming agents like psyllium husk. 5

Safe Pharmacological Options

• Osmotic laxatives (polyethylene glycol, lactulose) are safe during pregnancy. 5
• Hydrocortisone foam is safe in the third trimester with no adverse events compared to placebo in a prospective study of 204 patients. 5
• Short-term topical corticosteroids (≤7 days) can reduce inflammation but must be limited. 5
• Avoid stimulant laxatives—safety data during pregnancy are conflicting. 5

Management of Thrombosed External Hemorrhoids in Pregnancy

• For presentation within 72 hours, surgical excision under local anesthesia provides faster symptom resolution and lower recurrence rates. 5
• For presentation beyond 72 hours, conservative management with stool softeners and topical analgesics is preferred. 5
• Approximately 0.2% of pregnant women require urgent hemorrhoidectomy for incarcerated prolapsed hemorrhoids. 5

Common Pitfalls and How to Avoid Them

• Do not blindly attribute all anorectal symptoms to hemorrhoids—up to 20% of patients have coexisting anal fissures, and other conditions (abscess, fistula, cancer) may be the primary cause. 1, 2
• Never delay colonoscopy in patients with atypical bleeding, anemia, or risk factors for colorectal cancer—hemorrhoids are a diagnosis of exclusion for significant bleeding. 1, 2
• Avoid prolonged corticosteroid use (>7 days)—this causes perianal tissue thinning and increases injury risk. 1, 2, 5
• Do not perform rubber band ligation on external or thrombosed hemorrhoids—it causes severe pain when applied below the dentate line. 1, 2
• Recognize patients with portal hypertension or cirrhosis may have anorectal varices rather than true hemorrhoids—standard hemorrhoidectomy can cause life-threatening bleeding in this population. 2
• In immunocompromised patients, watch for necrotizing pelvic sepsis—severe pain, high fever, and urinary retention after any hemorrhoid procedure require emergency evaluation. 1
