Treatment of perianal fistula: analysis of 108 cases

ABSTRACT

One hundred and eight patients who underwent treatment for peri-anal fistula have been studied. Eighty-nine patients had a low anal fistula while 19 patients had high fistulae. Low fistulae were treated by fistulotomy achieving uniformly good results. The difficult high anal fistulae were treated by two stage fistulotomy [n=6], cutting seton [n=9], and re-routing technique [n=4]. The techniques and outcome of treatment are discussed
