[Impact of endorectal advancement flaps in fecal incontinence].
OBJECTIVE
The aim of this study was the prospective evaluation of the functional results of a series endorectal advancement flaps in the treatment of complex anal fistulas.


METHODS
A total of 90 patients were operated on for a complex anal fistula by means of fistulectomy and endorectal advancement flap. The functional results were evaluated using the Wexner continence scale and an anorectal manometry study before and after surgery.


RESULTS
There were seven patients with fistula recurrence (7.7%) and the same surgical procedure was performed on five of them, resulting in healing in all cases. Significant reductions in maximum resting pressure (83.85+/-30.96 vs 46.51+/-18.67; p<0.001) and maximum squeeze pressure (220.97+/-100.21 vs 183.06+/-75.36; p<0.001) were seen 3 months after surgery. On the continence scale, 80% of patients had a normal continence with a value of 0 on the postoperative Wexner scale, while 20% recorded changes in continence values, most of them lower than 3 points.


CONCLUSIONS
Endorectal advancement flap is an effective surgical procedure in complex anal fistulas treatment, with a low recurrence rate. Only 20% of the patients showed changes in the continence value.
