Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The standard treatment of anal fissure in the netherlands (ISDN ointment) is being compared to a relatively new treatment (injection of Botox in the internal anal sphincter). The study hypothesis is that after 4 months, Botox has healed more patients than ISDN. The comparison is done blinded for the surgeon and the patient.
