In current practice, patients with a single-tract mid-high or high cryptoglandular anal fistula often first undergo placement of a loose seton before definitive sphincter-preserving surgery. Although this staged approach is widely used, high-quality evidence showing that preoperative seton placement improves healing or other patient outcomes is limited.\n\nThe SETON trial is a multicenter, randomized, controlled non-inferiority trial that compares two accepted treatment strategies: loose seton placement for approximately 8 weeks followed by definitive sphincter-preserving surgery versus direct sphincter-preserving surgery without prior seton placement. The study aims to determine whether omitting routine seton placement is not inferior in terms of fistula closure 26 weeks after the final surgical intervention.\n\nSecondary outcomes include recurrence, postoperative complications, re-interventions, pain, continence, fistula-related quality of life, generic quality of life, return to work, and healthcare and societal costs. The results of this trial may help determine whether a routinely used treatment step can be safely omitted, potentially reducing treatment burden, shortening the treatment pathway, and lowering costs.",[28],"Cryptoglandular Perianal Fistula","RECRUITING","2026-09-01",{"date":32,"type":33},"2026-09-08","ACTUAL",{"date":35,"type":33},"2026-01-01",{"date":37,"type":22},"2029-01-01",{"name":39,"class":40},"Proctos Kliniek","OTHER",2,""]
