Simplified dressing change after surgery for high anal fistula: A prospective, single centre randomized controlled study on loose combined cutting seton (LCCS) technique

Abstract

BackgroundDressing change is the most important part of postoperative wound care. The aim of this study was to evaluate whether a more effective, simple and less painful method of dressing change for anal fistulas could be found without the need for debridement and packing. Data related to postoperative recovery were recorded at postoperative days 3, 7, 14, 21 and 180.MethodsIn this experiment, 76 subjects diagnosed with high anal fistula were randomly divided into a simplified dressing change (SDC) group and a traditional debridement dressing change(TDDC) group according to a ratio of 1:1.ResultsThe SDC group had significantly fewer pain scores, bleeding rates, dressing change times, inpatient days and lower average inpatient costs than the TDDC group. There were no significant differences in wound healing time, area and depth and Wexner score between the two groups.ConclusionsStudies have shown that the use of simplified dressing changes does not affect cure or recurrence rates, but significantly reduces dressing change times and pain during changes, reducing patient inpatient length of stay and costs.
