Treatment of Internal Hemorrhoids
Begin with conservative management for all grades of internal hemorrhoids, escalate to rubber band ligation for persistent grade I-III disease, and reserve surgical hemorrhoidectomy for grade III-IV hemorrhoids that fail office procedures or present with complications such as anemia. 1
Initial Conservative Management (First-Line for All Grades)
All patients with internal hemorrhoids must start with dietary and lifestyle modifications before any procedural intervention 1:
- Increase dietary fiber to 25-30 grams daily using psyllium husk (5-6 teaspoons mixed with 600 mL water daily) to soften stool and reduce straining 1, 2
- Adequate fluid intake to prevent constipation and maintain soft stools 1
- Avoid prolonged sitting and straining during defecation 2
- Sitz baths (warm water soaks) reduce inflammation and discomfort 1
Pharmacological Adjuncts for Symptom Relief
- Topical lidocaine 1.5-2% provides symptomatic relief of local pain and itching 1
- Topical corticosteroids may reduce perianal inflammation but must be limited to ≤7 days maximum to prevent mucosal thinning 1, 2
- Oral flavonoids (phlebotonics) relieve bleeding, pain, and swelling, though 80% of patients experience symptom recurrence within 3-6 months after cessation 1
Critical Diagnostic Requirements Before Treatment
Never attribute rectal bleeding or anemia to hemorrhoids without proper evaluation 1:
- Anoscopy should be performed when feasible to visualize internal hemorrhoids and exclude other anorectal pathology 1, 2
- Colonoscopy is mandatory if fecal occult blood is positive, anemia is present, or the patient is ≥50 years old or has colorectal cancer risk factors 1
- Hemorrhoids alone do not cause positive stool guaiac tests—fecal occult blood must not be attributed to hemorrhoids until the colon is adequately evaluated 1
- Anemia from hemorrhoids is rare (0.5 cases per 100,000 population); colonoscopy is required to exclude inflammatory bowel disease or colorectal cancer 1
- Persistent anal pain is not typical of uncomplicated internal hemorrhoids and suggests alternative diagnoses such as anal fissure (present in up to 20% of hemorrhoid patients), abscess, or thrombosis 1
Office-Based Procedures (Second-Line for Persistent Grade I-III Disease)
Rubber Band Ligation (Preferred Office Procedure)
Rubber band ligation is the most effective office-based procedure and should be the first procedural intervention for persistent grade I-III internal hemorrhoids after conservative management fails 1:
- Success rates: 70.5-89% depending on hemorrhoid grade, with approximately 90% of patients asymptomatic at 1-year follow-up 1
- Long-term outcomes: 69% remain asymptomatic at 10-17 years 1
- More effective than sclerotherapy and requires fewer repeat treatments than infrared photocoagulation 1, 3
Technique and Safety
- Place bands ≥2 cm proximal to the dentate line to avoid severe pain (somatic sensory nerves are absent above the anal transition zone) 1
- Can be performed in office without anesthesia using commercially available suction devices 1
- Up to 3 hemorrhoidal columns may be banded per session, though many practitioners prefer 1-2 columns at a time 1
Complications
- Pain (5-60% of patients): typically minor, manageable with sitz baths and over-the-counter analgesics 1
- Other complications (≈5%): abscess, urinary retention, band slippage, prolapse/thrombosis of adjacent hemorrhoids 1
- Severe bleeding: may occur when eschar sloughs, typically 1-2 weeks post-treatment 1
- Necrotizing pelvic sepsis (rare but serious): increased risk in immunocompromised patients (uncontrolled AIDS, neutropenia, severe diabetes) 1
Alternative Office Procedures (Less Preferred)
- Injection sclerotherapy: suitable for grade I-II hemorrhoids, with 89.9% improvement rate, but no proven superiority over conservative management alone 1
- Infrared photocoagulation: 67-96% success rates for grade I-II hemorrhoids, but requires more repeat treatments than rubber band ligation 1, 4
- Bipolar diathermy: 88-100% success rates for bleeding control in grade II hemorrhoids 1
Surgical Management (Reserved for Grade III-IV or Failed Conservative/Office Therapy)
Indications for Hemorrhoidectomy
Surgical hemorrhoidectomy is indicated for 1:
- Failure of medical and office-based therapy
- Symptomatic grade III-IV hemorrhoids
- Mixed internal and external hemorrhoids
- Hemorrhoids with anemia from chronic bleeding
- Concomitant anorectal conditions (fissure, fistula) requiring surgery
Surgical Technique
Conventional excisional hemorrhoidectomy (Milligan-Morgan open or Ferguson closed technique) is the most effective treatment overall, particularly for grade III-IV hemorrhoids 1, 2:
- Recurrence rate: 2-10% (lowest of all treatment modalities) 1, 2
- Success rate: 90-98% 1
- Ferguson (closed) technique may offer slightly improved wound healing compared to open technique 1
Postoperative Expectations
- Postoperative pain requires narcotic analgesics 1
- Most patients do not return to work for 2-4 weeks 1
- Complications: urinary retention (2-36%), bleeding (0.03-6%), anal stenosis (0-6%), infection (0.5-5.5%), incontinence (2-12%), sphincter defects (up to 12%) 1
Procedures to Avoid
- Anal dilatation should be abandoned: 52% incontinence rate at 17-year follow-up and causes sphincter injuries 1
- Cryotherapy is rarely used: prolonged pain, foul-smelling discharge, and greater need for additional therapy 1
- Stapled hemorrhoidopexy: promising results but lacks long-term follow-up data; complications include rectal perforation, retroperitoneal sepsis, and pelvic sepsis 1
Management of Thrombosed External Hemorrhoids (Distinct from Internal Hemorrhoids)
Early Presentation (≤72 Hours)
Complete surgical excision under local anesthesia within 72 hours provides faster pain relief and lower recurrence rates compared to conservative management 1, 2:
- Excision should be complete—simple incision and drainage is contraindicated due to persistent bleeding and higher recurrence rates 1, 2
- Can be performed as an outpatient procedure under local anesthesia 1
Late Presentation (>72 Hours)
Conservative management is preferred after 72 hours, as natural resolution has typically begun 1:
- Topical 0.3% nifedipine with 1.5% lidocaine ointment applied every 12 hours for 2 weeks achieves 92% resolution rate (vs. 45.8% with lidocaine alone), with no systemic side effects 1, 2
- Topical nitrates show good results but are limited by high incidence of headache 1
- Topical heparin significantly improves healing, though evidence is limited 1
- Stool softeners, oral analgesics, and sitz baths for symptomatic relief 1
Common Pitfalls to Avoid
- Never use topical corticosteroids for >7 days—prolonged use causes perianal and anal mucosal thinning 1, 2
- Never attribute anemia or positive fecal occult blood to hemorrhoids without colonoscopy 1
- Never perform simple incision and drainage of thrombosed hemorrhoids—complete excision is required 1, 2
- Avoid rubber band ligation in immunocompromised patients due to increased risk of necrotizing pelvic infection 1
- Do not assume all anorectal symptoms are hemorrhoids—up to 20% have concomitant anal fissures 1
