[Comparative characteristics of the methods of surgical treatment of extrasphincteric rectal fistulas].

The number of recurrences ranged from 2.1% to 14.3% depending on the degree of fistula complexity. Fistulectomy with suturing of its stump by dosage sphincterotomy is indicated in case of extrasphincteric fistulas without cicatricial and inflammatory changes in the intestinal wall and pararectal cellular spaces. Fistulectomy with suturing of the sphincter should be accomplished only in patients with non-branching extrasphincteric fistulas without inflammatory changes in pararectal cellular spaces. The technic of ligation may be employed in most complex forms of rectal extrasphincteric fistulas. A variant of surgery when ligature is put during the operative procedure and the wound is partially closed makes it possible to obtain adequate functional results.
