A comparative study of ligation of intersphincteric fistula tract (LIFT) and conventional fistulotomy in treatment of fistula-in-ano

Abstract

Background: A hospital randomized control study was conducted at a tertiary care Hospital, to compare outcomes between the Ligation of Intersphincteric Fistula Tract (LIFT) technique and conventional fistulotomy for the treatment of low trans-sphincteric fistula in ano, including 50 patients of low trans-sphincteric fistula in ano randomly divided into two groups. LIFT technique was used in first group while Conventional Fistulotomy was performed in another. Mean duration of operation was significantly less and mean hospital stay, post-operative pain and analgesics need was significantly less in cases operated with LIFT. Mean time for complete healing was significantly less in cases operated with LIFT technique and the difference in complication rate was statistically nonsignificant. Recurrence was reported in 3 (12%) and 1 (4%) cases operated by LIFT and fistulotomy respectively. Ligation of Intersphincteric Fistula Tract (LIFT) procedure is effective and preferred sphincter saving technique for fistula-in-ano. Despite slightly more recurrence, LIFT procedure has certain advantages over standard fistulotomy like shorter operative time, less postoperative pain, shorter hospital stay and faster wound healing and early resumption of normal duties.
