Abstract

An anal fissure, or fissure-in-ano, is a linear or an oval-shaped tear distal to the dentate line in the anal canal. Patients afflicted with this disorder most commonly complain of severe pain with bowel movements as well as bright red blood per rectum. Anal fissures are assumed to be very common although it is difficult to estimate disease prevalence since diagnosis of anorectal disorders is generally inaccurate. In addition, it is likely that a large proportion of patients with anal fissures never seek medical care and thus the condition is much more prevalent in the general population as compared to what is seen in clinical practice. In one survey, 80% of participants with symptoms attributed to the anorectum did not consult a physician.1
