[Treatment of chronic anal fissures: report of 31 cases].

A prospective study evaluating the surgical technique used in the treatment of chronic anal fissures, which is fissurectomy, partial sphincterotomy and anoplasty, was carried out in University Teaching Hospital Dakar. Thirty one patients with chronic anal fissures (20 males and 11 females) with average age 38 years and mean consultation period of 3 years, were treated with this technique. The delay of healing was between 4 to 12 weeks for a mean period of six weeks with 27 cases healed before 2 months and 4 cases after. One patient developed transitory faecal incontinence, recurrences, anal stenosis, haemorrhoidal relapses. noticed after simple lateral sphincterotomy were not found in our study as written in the medical literature. The surgical treatment of chronic anal fissures by fissurectomy, partial sphincterotomy and anoplasty is an important corner stone in this pathology. However lately healing may be a source of discomfort for the patient.
