Abstract
Objective To compare the clinical effects of modified ligation of the intersphincteric fistula tract and incision-thread-drawing procedure. Methods Total 106 patients with complex anal fistula were se-lected as study subjects and were randomized divided into group A and group B by the random number table method, 53 cases in each group. Group A was treated with modified ligation of the intersphincteric fistula tract while group B was treated with incision-thread-drawing procedure. The cure rate and VAS pain scores 3d and 7d postoperative, hospitalization time, wound healing time, Wexner anal incontinence scores preoperative and postoperative and 1-year recurrence rate were compared between the two groups. Results There were no sig-nificant differences between the cure rate and recurrence rate of group A (96.23%, 5.66%) and group B (94.33%, 7.55%) (P>0.05). The VAS pain scores 3d and 7d postoperative of group A (2.82 ± 0.80, 1.03 ± 0.31) were lower than group B(3.61 ± 0.77, 2.26 ± 0.44) (P<0.05). The hospitalization time and wound healing time in group A [(14.53 ± 2.49) d, (18.62 ± 3.77) d] were shorter than those in group B[(18.51 ± 4.66) d, (23.17 ± 5.08) d] (P<0.05). On discharge, Wexner scores of both groups were significantly decreased (P<0.05). The Wexner score of group A (0.22±0.07) was lower than group B (0.30±0.09) (P<0.05). Conclusion Compared with in-cision-thread-drawing procedure, modified ligation of the intersphincteric fistula tract has more advantages in re-ducing postoperative pain, shortening the hospitalization time and wound healing time and improving the anal function after surgery.关键词
