Approximately half of uncomplicated fissures resolve in 2-4 weeks with supportive care. [1] Fissures that heal with conservative treatment can recur, depending on the type of treatment the patient has undergone (ranging from 16% to more than 50%). [5] Chronic anal fissures frequently require surgical treatment.

Surgical treatment of anal fissures is associated with some degree of incontinence in approximately 14% of patients. [12]
