BACKGROUND Ligation of the intersphincteric fistula tract (LIFT) was developed to treat transsphincteric anal fistulas. The aftermath of a failed LIFT has not been well documented. METHODS Retrospective chart review of LIFT procedure for transsphincteric anal fistula between March 2012 and September 2016. RESULTS 53 patients with LIFT procedure were identified, 20 (37.7%) had persistent fistula with median followup of 4 months. Following LIFT, recurrence of fistula was transsphincteric (75%) or intersphincteric (25%) (p = NS). Persistent transsphincteric fistulas after LIFT were treated with seton (71.4%) followed by advancement flap (20%) or fistulotomy (50%). Of the recurrent intersphincteric fistulas, 50% underwent seton placement followed by fistulotomy, or advancement flap. Of the patients who underwent surgery after failed LIFT, 50% have had resolution of the fistula; 31.7% are still undergoing treatment. CONCLUSION Patients who underwent surgery after failed LIFT had 50% healing with placement of seton followed by fistulotomy or rectal advancement flap.
