Abstract:

Objective To observe the clinical effect of the application of intersphincteric incision and thread drawing surgery for the treatment of high complex anal fistula. Method A total of 90 patients with high complexity anal fistula admitted to Rongxian Integrated Traditional Chinese and Western Medicine Orthopedic Hospital in Yulin City from June 2021 to June 2024 were selected and randomly divided into an observation group of 45 cases and a control group of 45 cases using a random number table. The observation group was treated with intersphincteric incision virtual suture technique, while the control group was treated with conventional incision suture technique. The postoperative anal pain, wound healing time, and efficacy were compared between the two groups of patients. Result The clinical efficacy of the observation group was higher than that of the control group

(100.0% vs. 91.1%), and the difference was significant (P ＜ 0.01). The wound healing time and hospitalization time of the observation group were significantly shorter than those of the control group (P ＜ 0.001). Before surgery, there was no significant difference in incontinence scores between the two groups of patients compared to the control group (P ＞ 0.05); At 3 and 6 months after surgery, the incontinence scores of the observation group were significantly lower than those of the control group (P ＜ 0.05). On postoperative day 1 and 2, the visual analogue scale(VAS) scores of the observation group were significantly lower than those of the control group (P ＜ 0.01), but there was no significant difference in VAS scores between the two groups on postoperative day 7 and 10 (P ＞ 0.05). The incidence of postoperative complications in the observation group was 2.2%, with no patient recurrence. The incidence of complications and recurrence in the observation group were lower than those in the control group, and the differences were significant (P ＜ 0.01). Conclusion The surgical plan of intersphincteric incision with virtual hanging line can reduce the hospitalization period of patients, alleviate their pain, and achieve good short-term and long-term therapeutic effects.
