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
- von Roon (2009) BMJ Clin Evid 2009: 0415 [PubMed]
 
 
- 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
