Abstract:Objective: To explore the curative effect of ligation of intersphincteric fistula tract (LIFT) and incision-thread-drawing therapy for complex anal fistula and their influences on anal function and postoperative recurrence. Methods: A total of 90 patients with complex anal fistula admitted to the Anqing Municipal Hospital between January 2021 and August 2024 were retrospectively enrolled as the research subjects. According to the different surgical methods, they were divided into an incision-thread-drawing group (41 cases, incision-thread-drawing therapy) and a LIFT group (49 cases, LIFT). After treatment, clinical curative effect, perioperative indexes and anal function at 3 month after surgery in the two groups were observed, with the complications and recurrence recorded. Results: There was no significant difference in response rate of treatment between groups (all 100.00%, P>0.05). The wound healing time and length of hospital stay in LIFT group were shorter, intraoperative blood loss was less, scores of visual analogue scale (VAS) was lower, and the wound was smaller than those in incision-thread-drawing group at 7d after surgery (P<0.05). At 3 months after surgery, scores of wexner incontinence, anal canal rest pressure and anal maximal contraction pressure were decreased in both groups. Moreover, the difference value in wexner incontinence score before and after surgery in LIFT group was greater, while difference values in anal canal rest pressure and anal maximal contraction pressure before and after surgery were lower than those in incision-thread-drawing group, the differences were all statistically significant. (P<0.05). The incidence of complications in LIFT group was lower than that in incision-thread-drawing group (6.12% vs 21.95%, P<0.05). At 6 months after surgery, recurrence rate in LIFT group was lower than that in incision-thread-drawing group (0.00% vs 9.76%, P<0.05). Conclusion: The curative effect of LIFT and incision-thread-drawing therapy is similar in patients with complex anal fistula. However, LIFT is more advantageous in terms of controlling incision area, postoperative pain, healing and complications, which has fewer effects on anal function and lower recurrence rate at 6 months after surgery.
