Hemorrhoids are vascular-rich connective tissue cushions located within the anal canal.
Internal hemorrhoids lie proximal to the dentate line in the anal canal, whereas external hemorrhoids are located distal to the dentate line.
Hemorrhoidal disease presents as painless rectal bleeding or sudden onset of perianal pain with a tender palpable perianal mass.
Diagnosis is confirmed with visualization of the protruding tissue or anoscopic visualization.
Treatment includes increasing dietary fiber, rubber band ligation, infrared photocoagulation, sclerotherapy, or surgical hemorrhoidectomy.
Complications include recurrence or worsening of symptoms, excessive bleeding, nonreducible prolapse, and, rarely, pelvic sepsis.
