Abstract:
Objective To evaluate ligation of the intersphincteric fistula tract plus core-out fistulectomy for complex cryptoglandular anal fistulas.Methods Forty-one patients were divided into ligation and control group randomly.In ligation group (20 cases),patients underwent ligation of the intersphincteric fistula tract plus core-out fistulectomy procedure.While in control group (21 cases) fistulotomy on low sphincter with cutting-seton on high sphincter procedure was performed.The primary end points of the study were healing rate and continence by using the Wexner score.Secondary end points were postoperative pain in the third and seventh day with the use of the visual analog scale,length of hospital stay and followed measures for a recurrent fistula.Comparison of measurement data using independent samples t-test or paired samples t-test,compared with the count data using Fisher's exact test.Results There was no statistical difference in the healing rate between ligation group (90％) and control group (95％) (P ＞0.05).Postoperatively,one case in ligation group reported incontinence for gas,compared to 7 cases in control group,among these 7 cases 2 cases also had incontinence for watery stool.Statistical differences were found between two groups in Wexner scores,visual analog scale scores and length of hospital stay (P ＜0.05).Conclusion Ligation of the intersphincteric fistula tract plus core-out fistulectomy is an economical,safe,little painful,recovery enhanced and minimally invasive technique to treat complex anal fistulas.
