: The ligation of the intersphincteric fistula tract (LIFT) procedure is a treatment for fistulas that pass through the anal sphincter muscles, where a fistulotomy would be too risky.
During the treatment, a cut is made in the skin above the fistula and the sphincter muscles are moved apart. The fistula is then sealed at both ends and cut open so it lies flat.
This procedure has had some promising results so far, but it’s only been around for a few years, so more research is needed to determine how well it works in the short and long term.
