OBJECTIVE: As the short-term outcomes may overestimate the true success rates of sphincter-sparing techniques, and follow-up protocols that were reported based on clinical criteria do not ideally reflect real world outcomes associated with complex perianal fistulas (CPF), this study aimed to reveal clinically and three dimensional endosonograpy confirmed long-term outcomes and analyze the factors associated with recurrences of ligation of intersphincteric fistula tract (LIFT) procedure.
