II. Definitions
- Internal Hemorrhoid
- Dilation of anorectal vessels above Dentate Line
III. Symptoms
- Painless Rectal Bleeding
- Incomplete Defecation
- Prolapsed rectal mass
- Early: Prolapses with straining and then retracts
- Later: Prolapses with coughing, sneezing, lifting
- Chronic mucus discharge with excessive wetness
- Local anal irritation and soils clothes
- Irreducible, incarcerated prolapsed Hemorrhoid
IV. Signs: With Anoscopy
- Anorectal mass above Dentate Line
- Rectal mucosa bulging with reddish-purple mass
- Locations
- Right Anterior
- Right Posterior
- Left Lateral
V. Complications
- Iron Deficiency Anemia (from heavy bleeding)
- Incarcerated prolapsed Hemorrhoid
VI. Grading: Internal Hemorrhoid
- Grade I
- Present without prolapse
- Usually asymptomatic
- Grade II
- Some prolapse with spontaneous regression
- Grade III
- Prolapse with manual replacement
- Grade IV
- Prolapse with inability to replace Hemorrhoid
VII. Management: General
- See Hemorrhoid Management
- Non-pharmacologic approaches should be incorporated in all Hemorrhoid Management
- Colonoscopy should be considered in all patients with anorectal bleeding or presumed Internal Hemorrhoids
VIII. Management: Procedures
- Older Techniques
- Surgical Excision (Hemorrhoidectomy)
- Most effective to decrease recurrent symptoms in Grade 3-4 Internal Hemorrhoids and mixed Hemorrhoids
- Removes symptomatic and redundant Hemorrhoidal tissue to reduce pain and complications
- Diathermy/ultrasonic adjuncts to procedure: Ligasure, Harmonic Scalpel
- Absence from work for up to 4-6 weeks (much longer than with Rubber band ligation)
- More painful post-operatively than Rubber band ligation and other procedures (e.g. stapled Hemorrhoidectomy)
- Complications: Perianal Skin Tags, Perirectal Abscess, Anal Fistula, anal leakage, anal stenosis and bleeding
- Most effective to decrease recurrent symptoms in Grade 3-4 Internal Hemorrhoids and mixed Hemorrhoids
- Sclerotherapy
- Used in Europe but not in United States
- Less effective than Rubber band ligation or Hemorrhoidectomy
- Cryosurgery
- Rectal discharge
- Surgical Excision (Hemorrhoidectomy)
- Newer Techniques
- Rubber Band ligation (Baron Ligation)
- Indicated for Grades I to III Internal Hemorrhoid
- Highly effective first-line management of Internal Hemorrhoids
- Infrared Coagulation (IRC)
- Indicated for Grades I to III Internal Hemorrhoid
- Bipolar Electrocoagulation (BICAP)
- Indicated for Grades I to III Internal Hemorrhoids
- Radiofrequency ablation
- Apply to Hemorrhoid for 2 seconds
- Apply several places along Hemorrhoid
- Low-Voltage direct current (Ultroid)
- Indicated for Grades I to IV Internal Hemorrhoid
- Stapled Hemorrhoidectomy (Stapled Anopexy)
- Alternative management of Grade II to IV Hemorrhoids
- Interrupts Hemorrhoid blood supply by removing proximal mucosa and submucosa
- Staples are placed 4 cm above the Dentate Line circumferentially and bury into the mucosa over time
- Revisions are required twice as often as with Hemorrhoidectomy
- Common procedure in Europe
- High rate of persistent complications (30%)
- Pain post-Defecation
- Fecal urgency
- Awareness of staples in the Rectum for months after the procedure
- Bleeding at the staple site
- Stenosis (difficult to treat and may result in colostomy)
- Hemorrhoidal Artery Ligation (Transanal Hemorrhoidal Dearterialization)
- Experimental technique for Grade 2-3 Internal Hemorrhoids
- Ligation of superficial artery that lies just proximal to affected Hemorrhoid

- Rubber Band ligation (Baron Ligation)
IX. Management: Procedure Selection
- Grade I-II Internal Hemorrhoids
- Rubber Band ligation (Baron Ligation)
- Infrared Coagulation (IRC)
- Bipolar Electrocoagulation (BICAP)
- Low-Voltage direct current (Ultroid)
- Grade III-IV Internal Hemorrhoids
- Stapled Hemorrhoidectomy (Stapled Anopexy)
- Surgical Excision (Hemorrhoidectomy)
X. Management: Postoperative analgesia
- NSAIDs
- Opioid Analgesics
- Compounded preparations that offer post-operative analgesia
- Metrogel 10% applied topically three times daily
- Glyceryl Trinitrate ointment 0.2% applied twice daily
- Topical Nifedipine 0.3% and Lidocaine 1.5% ointment applied twice daily
