The Long-Term Efficacy of Fissurectomy and Botulinum Toxin Injection for Chronic Anal Fissure in Females

Abstract

Fissurectomy and botulinum toxin injection for the treatment of chronic anal fissure in females seems to be effective in the medium-term but there is a high rate of late recurrence. However, only a minority of patients proceed to more invasive surgical intervention, which may make it a useful option in patients not suitable for lateral sphincterotomy.
