The effect of suture selection in complex anal fistulas on the success of cutting seton placement and patient comfort

OBJECTIVE: The aim of our study was to compare the success rates of suture selection, recovery times and pain associated with local wound infection and seton placement in patients undergoing cutting seton placement for complex anal fistula. METHODS: The study included a total of 90 patients who were admitted with the diagnosis of complex anal fistula between January 2015 and July 2018. RESULTS: The first session and other revision appointments demonstrated that the number of patients who required fistulotomy was significantly higher in group-1 as the seton failed to complete the transection (p = 0.001). When the patients were asked to rate pain for 3 different conditions according to numeric rating scale (NRS), the patients in group-2 had significantly higher pain in all 3 cases compared to the patients in group-1 (p 0.001). The impact of the suture material on local infection was examined and it was determined that the results of cultures for seton material were significantly more positive in group-1 (p = 0.001). CONCLUSIONS: We conclude that a multi-stage tight seton placement with silk material can lead to satisfactory results by aiming to shorten the cutting time of silk seton.
