Clinical Value of Transrectal Three-dimensional Ultrasound before Surgery in the Diagnosis and Classification of Internal Opening of Complex Anal Fistula and Its Impact on Surgery Efficacy
Objective:To explore the clinical value of transrectal three-dimensional ultrasound before in the diagnosis and classification of internal opening of complex anal fistula and its impact on surgery efficacy.Methods:84 patients with complex anal fistula who were admitted to our hospital for surgery treatment from January 2021 to June 2022 were selected,they were divided into study group and control group according to the random number method,42 cases per group.Control group underwent routine transrectal ultrasound examination before surgery,and study group underwent transrectal three-dimensional ultrasound examination before surgery.The diagnostic accuracy rate before surgery,Parks type accuracy rate,surgery efficacy,hospital time,wound healing time,anal function before surgery and after surgery,complications after surgery,and recurrence rate of internal opening of anal fistula were compared between two groups.Results:The diagnostic accuracy rate before surgery of internal opening of anal fistula in study group was significantly higher than that in control group(P＜0.05).The diagnosis accuracy rate before surgery of sphincter interstemal type,trans sphincter type,sphincter upper type,sphincter appearance type in study group were significantly higher than those in control group(P＜0.05).The cure rate in the study group was 66.67％,significantly higher than 42.86％in the control group(P＜0.05).The Wexner score of anal incontinence in the study group was signifiicantly lower than that in the control group at 6 months after surgery(P＜0.05),and the hospital stay and wound healing time in the study group were shorter than those in the control group(P＜0.05).There was no statistically significant difference in the incidence of complications after surgery and recurrence rate within 6 months between two groups(P＞0.05).Conclusion:Transrectal three-dimensional ultrasound diagnosis can accurately diagnose the opening and course of anal fistula,which is beneficial for improving the overall treatment effect of complex anal fiistula,and protecting anal function.
