The aim of this study was to look at our experience of the LIFT procedure in CD patients on long\u2010term follow\u2010up. Specifically, we aimed to determine the fistula healing rate after the LIFT procedure after more than 12\u00a0months follow\u2010up and to identify any prognostic factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Retrospective study of patients with trans\u2010sphincteric Crohn's fistula tracts treated with the LIFT procedure between January 2011 and October 2015. Complete fistula healing as well as clinical outcomes were analysed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Data were available for 23 patients. After a median follow\u2010up of 23\u00a0months, LIFT site healing was 48%. Patients with healed LIFT had a median follow\u2010up time of 10.5\u00a0months, while patients with failed LIFT had a median follow\u2010up time of 31\u00a0months (<jats:italic>P\u00a0<\/jats:italic>=<jats:italic>\u00a0<\/jats:italic>0.04). Median time to failure was 9\u00a0months for patients with follow\u2010up &gt;\u00a01\u00a0year. Most patients failed within 1\u00a0year (9\/12; 75%) of the procedure. In multi\u2010site CD, the LIFT procedure was more likely to be successful in those with small bowel disease (<jats:italic>P\u00a0<\/jats:italic>=<jats:italic>\u00a0<\/jats:italic>0.04) compared with colonic disease (<jats:italic>P\u00a0<\/jats:italic>=<jats:italic>\u00a0<\/jats:italic>0.02). Other factors such as preoperative use of biological therapies, presence of a seton, previous repair attempts, fistula position, type or number of fistulas, multiple fistula tracts, smoking status and other associated perianal disease did not appear to influence LIFT healing rates.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The LIFT procedure offers reasonable long\u2010term success in the treatment of perianal trans\u2010sphincteric fistulas associated with CD.
