Background: Prior studies focus primarily on surgical outcomes of anal fistula treatment, such as healing rates, rather than patient-reported outcomes, such as postoperative pain, which could influence surgical choice. Objective: To compare pain scores at 6 and 24 h postoperatively between laser closure and ligation of the intersphincteric tract for anal fistula. Design: Prospective, double-blinded randomized controlled trial. Settings: A quaternary hospital in Malaysia. Patients: Patients aged 18-75 years with high transsphincteric fistulas. InterventionFistula laser closure versus ligation of the fistula tract (LIFT) treatment. Main Outcome Measures: Pain scores, continence, quality of life (QOL), operative time, and treatment failure were compared using chi-square, Fisher's exact test, student t-test, or Mann-Whitney with p < 0.05 denoting statistical significance. Results: Fifty-six patients were recruited (laser, n = 28, LIFT, n = 28). Median pain scores for laser versus LIFT at 6 h postoperatively were 1.0 versus 2.0 (Rest, p = 0.213) and 3.0 versus 4.0 (Movement, p = 0.448), respectively. At 24 h, this reduced to 2.5 in both arms at rest (p = 0.842) but increased to 4.8 versus 3.5 on movement (p = 0.383). Median operative time for laser was significantly shorter (32.5 min) than LIFT (p < 0.001). Laser treated patients trended toward quicker return to work (10.5 vs. 14.0, p = 0.181) but treatment failure was similar (54% vs. 50%, p = 0.71). No patients developed postoperative incontinence. Mean SF-36 scores increased from baseline (67.1 +/- 17.0; 95% CI 63.6-82.4 vs. 71.3 +/- 11.4; 95% CI 64.0-75.0) to 6 months postoperatively (77.7 +/- 21.0; 95% CI 57.0-80.3 vs. 74.0 +/- 14.3; 95% CI 67.6-81.4) regardless of the type of surgery (P > 0.05). Limitations: Patients with prior fistula surgery (approximately 20%) led to heterogeneity. The total laser energy delivered varied depending on fistula anatomy. Conclusion: Laser fistula closure is an alternative to LIFT, with similar postoperative pain and shorter operative time despite more complex fistula anatomy in the laser arm, with a greater improvement in QOL.
