Comparison of the Efficacy of Laser and Hybrid Seton Methods in the Treatment of Perianal Fistula.

Objective: To compare the efficacy and postoperative complications of laser and hybrid seton methods in the treatment of perianal fistula (PF).

Study design: A descriptive cross-sectional study. Place and Duration of the Study: Department of General Surgery, University of Health Sciences, Bursa Yuksek Ihtisas Training and Research Hospital, Bursa, Turkiye, from January 2021 to April 2022.

Methodology: A total of 76 patients, with 46 in the hybrid seton group and 30 in the laser group, were included in the study. Perianal fistula classification was based on preoperative magnetic resonance imaging. The Likert satisfaction scale was assessed for patient satisfaction and the Cleveland Clinic Florida Faecal Incontinence (CCF-FI) scoring system was used for incontinence. Treatment outcome was determined based on success rate and postoperative faecal incontinence.

Results: The mean age of the patients was 43 ± 13 years and 59 (78%) of them were male. Forty-seven (62%) patients had simple fistula. Acute and late complications were significantly higher in the hybrid seton group than in the laser group (p <0.001). According to the Likert satisfaction scale, the rate of unsatisfied patients was significantly higher in the laser group than in the hybrid seton group (p = 0.02). According to the CCF-FI scoring system, incontinence was significantly higher in the hybrid seton group than in the laser group (p = 0.01). Treatment failure was higher in the laser group (p = 0.03).

Conclusion: The laser method has lower intraoperative / postoperative complications, but higher treatment failure and lower patient satisfaction compared to the hybrid seton method.
