Purpose: To estimate the risk of recurrent fissure in ano after sphincter preserving treatments.
Methods: A retrospective case note review, combined with a telephone survey was conducted for all patients treated for a chronic anal fissure between 1998 and 2008.
Results: Six hundred and twelve patients (303 women: mean age, 39 years; range, 16-86 years) were treated for chronic anal fissure between 1998 and 2008. Topical diltiazem 2% was initially prescribed for 8 weeks. The fissure did not heal in 141 patients. These patients (61 women: mean age, 30 years; range, 15-86 years) were treated with 100 IU botulinum A toxin (Botox) injection combined with a fissurectomy under general anaesthesia. Thirty eight patients suffered a recurrence of their fissure within two years. Thirty-four healed with further medical or sphincter conserving surgical therapy while four required a lateral internal sphincterotomy.
Conclusion: The vast majority of patients with chronic anal fissure can be treated with sphincter conserving treatments. This may require several interventions before healing can be achieved. Assessment for recurrence after ’conservative’ treatments requires a minimum of two-year follow-up.
