Anorectal disorders.

Common anorectal disorders can produce one or more of the following symptoms: pain, protrusion, pruritus, bleeding or discharge. The cause may be cryptitis, anal fissure, hemorrhoids, anorectal abscess, fistula in ano, neoplasm, condylomata acuminata, pilonidal cyst or inflammatory bowel disease. Each disorder is suggested by its characteristic history. Adequate examination by proctosigmoidoscopy will usually confirm the presence of the suspected disease.
