RCT on LIFT Versus Modified Parks Technique Versus Two-Stage Seton

LIFT is a sphincter-saving procedure that is based on the concept of secure closure of the internal opening and concomitant removal of infected cryptoglandular tissue in the intersphincteric plane. Modified Parks technique involves adequate drainage of the intersphincteric space by extending the internal anal sphincterotomy. Placement of seton in the fistula track has been used for a long time and is still being currently used. Drainage two-stage seton is used to promote adequate drainage of infection and can be employed as a definitive treatment of anal fistula. This present randomized study aimed to compare LIFT, modified Parks technique, and two-stage seton in treatment of complex anal fistula in terms of success of treatment and complication rates.
