Study Notes
Hemorrhoids: Pathophysiology and Anatomy
- Hemorrhoids develop when venous drainage of the anus is altered, leading to dilation of the venous plexus and connective tissue, resulting in outgrowth of anal mucosa from the rectal wall.
- The dentate line is the primary anatomic landmark for hemorrhoid development.
- The average length of the anus in adults is approximately 4 cm.
Types of Hemorrhoids
- Internal hemorrhoids are located above the dentate line and are usually painless due to visceral innervation.
- Symptoms of internal hemorrhoids include painless bright red bleeding, prolapse, and soiling.
- Visualization of internal hemorrhoids can be effectively performed using anoscopy.
- Typical anatomic planes or hemorrhoidal columns include left lateral, right anterior, and right posterior.
Treatment Options
- First-line conservative treatment for hemorrhoids focuses on dietary and lifestyle changes such as:
- High fiber diet (recommended intake: 25-35 g per day)
- Fiber supplementation
- Increased water intake
- Warm water (sitz) baths
- Stool softeners
- Primary office-based procedures for grade I to III internal hemorrhoids include:
- Banding
- Infrared photocoagulation
Classification of Internal Hemorrhoids
- Grade I: Asymptomatic outgrowth of anal mucosa due to engorgement of the venous plexus and connective tissue.
- Grade II: Hemorrhoid prolapses but spontaneously reduces.
- Grade III: Hemorrhoid prolapses and must be manually reduced; often associated with pruritus and soiling.
- Grade IV: Hemorrhoid prolapse that cannot be reduced.
Surgical Interventions
- Conventional techniques for recurrent and symptomatic grade III or IV hemorrhoids include closed or open hemorrhoidectomy.
- Complications of stapled hemorrhoidopexy include a higher likelihood of recurrent symptoms and prolapse.
Pathophysiology of Hemorrhoids
- Develop when venous drainage of the anus is altered, leading to dilation of the venous plexus and connective tissue.
- Results in outgrowth of anal mucosa from the rectal wall.
Anatomic Considerations
- Hemorrhoids can develop around the dentate line.
- Anus length in adults is approximately 4 cm.
Types of Hemorrhoids
-
Internal Hemorrhoids:
- Located above the dentate line.
- Typically painless due to visceral innervation.
- Symptoms include painless bright red bleeding, prolapse, and soiling.
Diagnostic Visualization
- Internal hemorrhoids can be effectively visualized using anoscopy, appearing as purplish bulges.
Hemorrhoidal Columns
- Typical anatomical planes or hemorrhoidal columns include:
- Left lateral
- Right anterior
- Right posterior
Conservative Treatment Options
- First-line intervention includes a high-fiber diet (25-35 g per day).
- Additional measures entail:
- Fiber supplementation
- Increased water intake
- Warm water (sitz) baths
- Stool softeners
Office-Based Procedures
- Primary procedures for grade I to III internal hemorrhoids are:
- Banding
- Infrared photocoagulation
Grading of Internal Hemorrhoids
-
Grade I:
- Asymptomatic; engorgement of underlying vascular structures.
-
Grade II:
- Prolapses but reduces spontaneously.
-
Grade III:
- Prolapses requiring manual reduction; often accompanied by pruritus and soilage.
-
Grade IV:
- Prolapse that cannot be reduced.
Surgical Interventions
- Closed or open hemorrhoidectomy are conventional techniques employed for recurrent and symptomatic grade III or IV hemorrhoids.
Complications of Treatment
- Stapled hemorrhoidopexy may lead to higher rates of symptom recurrence and prolapse.
