AFP, anal fistula plug; VAAFT, video-assisted anal fistula treatment; FiLaC, fistula-tract laser closure; LIFT, ligation of intersphincteric fistula tract; PERFACT, proximal superficial cauterization, emptying regularly fistula tracts and curettage of tracts; TROPIS, transanal opening of the intersphincteric space; IOEAUS, intraoperative endoanal ultrasonography.
a
No significant change in incontinence was noted, and numerical data were unavailable.
b
After reoperation, 87.6%.
c
No significant change in incontinence was noted; however, 1 patient had incontinence to gas with a score of 1 (by St. Mark’s incontinence score), which improved on subsequent follow-up.
