Abstract:
Objective To explore the clinical effect of the combination of virtual and solid with hanging line in the treatment of high anal fistula. Methods A total of 90 patients with high anal fistula were divided into treatment group and control group according to the random number table method, which 45 cases each.The treatment group was treated by the combination of virtual and solid suture, while the control group was treated by anal fistula incision and suture. Efficacy evaluation, postoperative pain score (VAS), wound healing time,anal function assessment (Wexner score), changes in anal resting pressure and maximum systolic pressure were performed after the two groups received relevant treatment to make a comparison of efficacy. Results The total effective rate was 97.8% in the treatment group and 84.4% in the control group, which the difference was statistically significant (χ2=4.939, P =0.026). Postoperative VAS score was (5.47±0.51) in the treatment group and (5.53±0.57) in the control group on the 1st day, showing no statistically significant difference (t =0.526,P =0.600).Treatment group (5.28±0.52, 4.47±0.67, 2.94±0.50) scores on the 7th, 10th,and 14th day, which were better than those of control group (5.81±1.53, 4.81±0.69, 3.22±0.32) scores (t =2.200, 2.389, 3.164,P =0.032, 0.019, 0.002). Treatment group wound healing time (28.33+2.09) is better than that of the control group (46.19+1.97) days (t=41.715, P <0. 001). Postoperative anal function Wexner score showed that the treatment group (0.76±0.69) score was significantly better than that of the control group (2.83±0.42)score (t =17.19, P <0.001). Before treatment, the anal repose pressure and maximum systolic pressure in the treatment group were (7.08±0.14, 21.39±1.89) kPa, while in the control group (7.11±0.28, 21.65±1.55) kPa, and the comparison showed no statistical signi?cance (t=0.623, 0.714, P=0.523, 0.478). After treatment, the anal resting pressure and the maximum systolic pressure in the treatment group were (6.93±0.50, 20.96 ±1.36) kPa and the control group were (6.60±0.29, 20.10 ±0.57) kPa. The comparison was statistically signi?cant (t=2.785, 3.821, P=0.007, P<0.001). Conclusion The combination of virtual and solid with hanging thread in the treatment of high anal ?stula has the characteristics of good anal function protection, less pain, quick recovery, simple operation and strong operability.
