Fissurectomy and anal advancement flap for anterior chronic anal fissure without hypertonia of the internal anal sphincter in females.
OBJECTIVE
Lateral internal sphincterotomy is considered the surgical treatment of choice for chronic anal fissure after failure of medical therapy but it risks continence. The aim of the study was to evaluate fissurectomy with advancement flap for anterior chronic anal fissure (CAAF) resistant to medical therapy.


METHODS
Sixteen women with CAAF without hypertonia of the internal anal sphincter, unresponsive to previous medical treatment, were included in the study. Absence of hypertonia was defined as a maximum anal resting pressure (MRP) of less than 85 mmHg. All patients underwent fissurectomy with an advancement skin flap.


RESULTS
Complete healing occurred in all patients within 30 days. The intensity and the duration of pain after defecation reduced from the first postoperative defecation. MRP before surgery and at 6 months showed no significant difference. At 1 month, four patients experienced a continence disturbance, two of whom had it preoperatively. At 12 months, two (12.5%) patients continued to experience a continence disturbance.


CONCLUSIONS
Fissurectomy with skin advancement flap resulted in complete healing and full relief of symptoms in all patients. There was a low incidence of continence disturbance.
