V-Y advancement flap as first-line treatment for all chronic anal fissures.
BACKGROUND
It was suggested that anal advancement flap be used to treat patients with chronic anal fissures that have failed medical management and have a low-pressure sphincter complex. We wished to assess anal advancement flap as a treatment for all chronic anal fissures.


METHODS
All patients with chronic anal fissures regardless of their previous management underwent V-Y advancement flap. Patient demographics, symptom duration, previous treatments, short-term postoperative outcome and long-term follow-up were recorded.


RESULTS
Fifty-four consecutive patients, median age 39 years (22-66), underwent a V-Y advancement flap over a 7-year period; 34 were men. Duration of symptoms ranged from 2 to 36 months with a median of 8 months. Forty-two patients (78%) had failed a previous therapy: glyceryl trinitrate (GTN) (25), GTN and diltiazem (16) and lateral sphincterotomy (one). Wound dehiscence occurred in three patients of which only one required a surgical intervention. On follow-up at 6 months, all but one patient had a healed wound and was asymptomatic.


CONCLUSIONS
We have shown excellent rates of healing of chronic anal fissures treated with a V-Y advancement flap regardless of sphincter pressures, previous treatment and symptom chronicity. These results show the technique can be applied to all chronic fissures with success and used as a primary therapy.
