Are two better than one? VALIFT: video-assisted ligation of the intersphincteric fistula tract—a combination of two minimally invasive techniques for treatment of transsphincteric perianal fistulas

Excerpt

Ligation of the intersphincteric fistula tract (LIFT) is one of many methods for treating transsphincteric anal fistulas. During this procedure, the fistula tract is dissected and ligated in the intersphincteric space, to close its lumen and prevent the fistula from recurring. The main advantage of this procedure over classic fistulectomy or fistulotomy operations is that both internal and external sphincters are left intact [1] and the risk of fecal incontinence after the operation is minimal. However, as in most techniques used to treat perianal fistulas, results vary depending on the complexity of the fistula. Due to this variability, many surgeons develop modifications of this technique, to achieve better results [2]. …
