Abstract：Objective To explore the clinical effect of sphincter preservation surgery treating anal fistula.Methods Fifty patients with anal fistula admitted to Fuyong People′s Hospital of Bao′an District in Shenzhen City from January 2017 to July 2019 were selected as the research objects.They were divided into control group (25 cases) and study group(25 cases) according to the random grouping method.The control group was treated with one-time incision and threaddrawing,the study group adopted the surgical treatment method of preserving the sphincter to preserve the mucosa.The one-time cure rates,anal pain,anal edema scores after surgery,incidence of complications,surgical operation time and hospitalization time were compared between the two groups.Results The one-time cure rate of the study group was higher than that of the control group,and the difference was statistically significant (P<0.05).The postoperative anal pain score and marginal edema score of the study group were lower than those of the control group,the differences weretatistically significant (P<0.05),the total incidence of postoperative complications in the study group was lower than that in the control group,and the operation time and postoperative hospital stay were shorter than those of the control group,the differences were statistically significant (P<0.05).Conclusion The implementation of the treatment plan of sphincter preserving sphincter in the treatment of anal fistula patients can effectively improve the quality of the operation and the treatment effect,alleviate the discomfort of the patients after surgery,reduce the incidence of postoperative complications,and optimize the surgical procedure,shorten the treatment and hospitalization time,which is worth promoting and applying.
