Abstract
Objective: To evaluate the effectiveness of the TROPIS technique (Transanal Opening of the Intersphincteric Space) in the treatment of anal fistulas at Viet Duc University Hospital. Subject and method: A prospective case series study was conducted from March 2022 to March 2024 on 40 patients with anal fistulas treated using the TROPIS technique. Postoperative follow-ups were scheduled regularly from 2 weeks to 12 months. Outcome measures included healing rate, recurrence rate, wound healing time, and preservation of anal continence. Result: The healing rate after the first surgery was 87.5%, increasing to 95% after a second procedure. The average wound healing time was 36 days. No early postoperative complications were recorded. All patients maintained good continence function (CCIS ≤ 7). Statistical analysis revealed significant differences in surgical outcomes across various Parks and St. James fistula classifications. Conclusion: The TROPIS technique is a safe and effective treatment for anal fistulas, particularly complex cases. It allows for the preservation of sphincter function and reduces recurrence rates.
