Hepatocellular carcinoma: Difference between revisions

Latest revision as of 23:02, 4 January 2026

Background

Anatomy of the anus.

Internal and external hemorrhoids divided by pectinate (dentate) line

Pathologic state cccurs when internal or external hemorrhoid plexus become engorged, prolapsed, or thrombosed
Bleeding is usually limited (surface of stool, on toilet tissue, at end of defecation)
- Passage of blood clots requires evaluation for colon lesions

Risk Factors

Constipation and straining at stool
Frequent diarrhea
Older age
IBD

Types

External hemorrhoid

Thrombosed external hemorrhoid

Internal hemorrhoid
- Originate above the dentate line
- Painless
External hemorrhoid
- Originate below the dentate line
- Painful

Internal hemorrhoid chart

Internal hemorrhoid grades
Grade	Description	Diagram	Picture
I	Luminal protrusion above dentate line No prolapse Painless bleeding
II	Prolapse with spontaneous reduction Prolapse during straining
III	Prolapse requires manual reduction Prolapse during straining
IV	Prolapse—nonreducible Can result in edema and strangulation

Treatment

Increase fiber
Sitz baths
Topical steroid - Hydrocortizone
Topical anti-spasmodic - Nifedipine
See also treatment by specific type:
- Internal hemorrhoid
- External hemorrhoid
