Abstract:

Objective To investigate the effects of the application of sphincter preserving hanging wire method in patients with complex anal fistulas. Method A total of 120 patients with complicated anal fistula who were admitted to Guangzhou Zengcheng District Central Hospital from March 2019 to March 2021 were randomly selected as the study subjects and divided into control and observation groups using the number table method, with 60 patients in each group. The control group was treated by conventional fistula resection, and the observation group was treated by sphincter preserving hanging wire method. Treatment outcomes, intraoperative conditions, as well as postoperative complication rates were compared between the 2 groups. Result patients in the observation group had a higher response rate to treatment than those in the control group (P ＜ 0.05), patients in the observation group had less intraoperative blood loss and a shorter operative time than the control group (P ＜ 0.05), and patients in the observation group had a lower rate of postoperative complications than those in the control group (P＜ 0.05). Conclusion The application of sphincter preserving hanging wire method in the treatment of patients with complex anal fistulas is highly effective, which may promote patient recovery and reduce the occurrence of postoperative complications.
