What this Trial Is About
High anal fistulas represent a surgical challenge due to high recurrence rates and risk of postoperative fecal incontinence. Several sphincter-preserving techniques have been developed to address these issues. Coring Out fistulectomy is a traditional sphincter-saving approach, while Transanal Opening of the Intersphincteric Space (TROPIS) is a recently introduced technique with promising outcomes. This randomized clinical trial aims to compare the efficacy, safety, and patient outcomes of TROPIS versus coring out fistulectomy in the management of high complex anal fistulas.
