A novel sphincter-sparing procedure for seton removal in complex perianal fistulas: the FiLaFlap technique.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundComplex perianal fistulas present a significant surgical challenge due to high recurrence rates and the need to preserve sphincter function. Fistula-tract Laser Closure (FiLaC™) is a minimally invasive technique that offers promising results, but incomplete closure of the internal opening remains a major cause of recurrence. To improve outcomes, we propose the FiLaFlap technique, which combines FiLaC™ with a mucosal advancement flap to enhance fistula healing.
methodsWe conducted a retrospective study of patients who underwent seton removal with the FiLaFlap procedure between January 2023 and September 2024. Postoperative data, including pain levels, complications, continence status, and follow-up outcomes, were collected prospectively. Patients underwent clinical evaluations and 3D endoanal ultrasound assessments at predefined intervals.
resultsA total of 24 patients (58.3% male, mean age 39.4 ± 12.4 years) were included. The mean time between seton placement and FiLaFlap was 5.95 ± 1.78 months. Postoperative pain was low (VAS 2.20 ± 0.97), and no major complications occurred. At 6 months, 91.6% of patients achieved clinical remission, while 83.3% had ultrasound-confirmed healing. Only one patient reported minor incontinence.
conclusionThe FiLaFlap technique appears to be a safe and potentially effective sphincter-preserving strategy for complex perianal fistulas, demonstrating high remission rates with minimal morbidity. Further studies with larger cohorts and extended follow-up are needed to validate these preliminary findings.
