Anal fissures – Knowledge for medical students and physicians

An anal fissure fissure-in-ano is a small, oval shaped tear in skin that lines the opening of the anus. Fissures typically cause severe pain and bleeding with bowel movements. Fissures are quite common in the general population, but are often confused with other causes of pain and bleeding, such as hemorrhoids. Anal fissures can occur at any age and have equal gender distribution. A small number of patients may actually have fissures in both the front and the back locations. Fissures located elsewhere off to the side should raise suspicion for other diseases see below and will need to be examined further.

Anal fissure

An anal fissure is a common, mostly benign, condition that can be acute or chronic. The diagnosis is usually made on history and physical examination, but further investigations are sometimes necessary. Primary fissures are usually benign and located in the posterior or anterior position. Secondary fissures are lateral or multiple and often indicate a more serious underlying pathology. The management of primary anal fissures is generally non-operative and includes increased dietary fibre, sitz baths, topical ointments and botulinum toxin injections.
