Clinical E cacy of Sphincter-retaining and Loose-seton erapy in Treating Patients with High Perianal Abscess

Objective To investigate the clinical efficacy of sphincter-retaining and loose-seton therapy in treating high perianal abscess.Methods Using randomized controlled trial,52 patients with high perianal abscess were randomly assigned to treatment group(n=26) treated with sphincter-retaining and loose-seton therapy and the control group(n=26) treated with perianal abscess radical surgery.The incidence of anal fistula 6 months after the treatment,healing time of incision,VAS scores of night pain 1 to 15 days after treatment,and sequelae of anal function 6 months later were observed and compared.Results Six months after treatment,the incidences of anal fistula of the treatment group and the control group were respectively 4.0% and 3.8%(P 0.05).The healing time of incision and night pain score of the surgery day and the 14 days after operation in the treatment group were shorter or slighter compared with those in the control group(P 0.05).After six-month follow-up,the anal function of treatment group was normal,and the control group had a 12.0% incidence of complications,the difference of which was of statistical significance(P 0.05).Conclusion The sphincterretaining and loose-seton therapy on high perianal abscess is better than radical surgery in terms of postoperative pain, healing time of incision and protection of anal function.
