[Treatment of chronic anal fissure].
Chronic anal fissure is a common benign anorectal problem in Western countries that substantially impairs the patient's life. Consequently, a rapid and effective solution is required. We reviewed the various treatments for chronic anal fissure described in the literature, with the aim of establishing a therapeutic protocol. We recommend surgical sphincterotomy (preferably open or closed lateral sphincterotomy) as the first therapeutic approach in patients with chronic anal fissure. However, we prefer the use of chemical sphincterotomy (preferably botulinum toxin) in patients aged more than 50 years old and in those with previous incontinence, risk factors for incontinence (previous anal surgery, multiple vaginal births, diabetes, inflammatory bowel disease, etc.), or without anal hypertonia, despite the higher recurrence rate with medical treatments, since this procedure avoids the greater risk of residual incontinence described in the literature with surgical sphincterotomy in this group of patients.
