Drainage Seton Versus External Anal Sphincter-Sparing Seton After Rerouting of the Fistula Tract in the Treatment of Complex Anal Fistula: A Randomized Controlled Trial

摘要

RESULTS: Sixty patients (56 men) with a mean age of 43 years were included. Mean operation time in group 1 was significantly shorter than group 2 (29.8 +/- 4.3 vs 43.8 +/- 4.5 min; p < 0.0001). The mean pain score at 24 hours in group 1 was 8.1 +/- 1.6 versus 5.3 +/- 1.3 in group 2 (p < 0.0001). Five patients (17%) in group 1 experienced complications versus 2 (7%) in group 2. All of the patients in group 1 required a second-stage fistulotomy versus 2 patients (7%) in group 2 (p < 0.0001). Time to complete healing in group 1 was significantly (p < 0.0001) longer than group 2 (103 +/- 47 vs 46 +/- 18 d). Four patients (13%) in group 1 and 1 patient (3%) in group 2 experienced persistence or recurrence of anal fistula (p = 0.35).
