Analysis of Influencing Factors on the Recurrence of Anal Fistula in Patients with Perianal Abscess after Incision and Drainage Surgery
Objective Analyze the influencing factors of anal fistula recurrence in patients with perianal abscess after incision and drainage surgery.Methods 120 patients with perianal abscess who underwent incision and drainage from July 2021 to June 2023 were selected as the observation subjects.According to the occurrence of anal fistula after surgery,they were divided into a group with anal fistula(n=38)and a group without anal fistula(n=82).General and clinical data of the two groups of patients were collected,and multivariate logistic regression analysis was used to analyze the influencing factors of postoperative recurrence of anal fistula in patients.Establish a logistic regression equation to evaluate the sensitivity,specificity,and accuracy of the model for predicting postoperative recurrence and formation of anal fistula.Results The body mass index(BMI)value of patients with anal fistula was significantly higher than that of those without anal fistula,and the proportion of simple incision and drainage was signifi-cantly higher than that of those without anal fistula.The proportion of pathogenic bacteria including in-testinal origin,deep abscess,and horseshoe shaped abscess was significantly higher than that of those without anal fistula(P＜0.05).Multivariate logistic regression analysis showed that BMI,intestinal ori-gin of pathogenic bacteria,deep abscess,and horseshoe abscess were risk factors for postoperative recur-rence and formation of anal fistula in patients with perianal abscess.Surgical approach(radical incision and drainage)was a protective factor for postoperative recurrence and formation of anal fistula in patients with perianal abscess(P＜0.05).The receiver operating characteristic(ROC)curve analysis results showed that the area under the curve(AUC)of the logistic regression model predicting postoperative recurrence and formation of anal fistula was 0.800(95％CI:0.728-0.872),with a sensitivity of 87.50％and a specificity of 72.50％.Conclusion The incidence of recurrent anal fistula is higher in patients with perianal abscess after incision and drainage surgery.Among them,high BMI,pathogenic bacteria origi-nating from the intestine,deep abscess,and horseshoe abscess are risk factors for postoperative recurrence of anal fistula.Early screening of high-risk patients with postoperative recurrence of anal fistula and ear-ly intervention can help reduce its incidence.
