RESUMEN
Objective:To investigate the effect of Zhitong-Rusheng Decoction on wound healing and serum fibronectin (FN) and epidermal growth factor (EGF) levels after anal fistula operation. Methods:A total of 102 patients after anal fistula operation in our hospital from March 2018 to March 2020 were randomly divided into control group (51 cases) and observation group (51 cases) according to the random number table method. The control group was treated with conventional western treatment, while the observation group was treated with Zhitong-Rusheng Decoction on the basis of control group. The two groups were treated for 3 weeks. The clinical symptoms were scored before and after treatment, and the levels of serum FN and EGF were detected by ELISA. The wound healing time, hematochezia disappearance time, wound longitudinal diameter and wound area before and after treatment were observed. The clinical efficacy was evaluated after treatment. Results:The total effective rate was 98.0% (50/51) in the observation group and 72.6% (37/51) in the control group, with significant difference between the two groups ( χ2=13.209, P<0.01). After treatment, the pain degree score, wound exudation score and granulation morphology score of the observation group were significantly lower than those in the control group ( t=15.448, 21.424, 28.641, P<0.001). After treatment, the wound healing time [(6. 04 ± 1.20) d vs. (9.42 ± 1.58) d, t=12.166] and the disappearance time of hematochezia [(15.72 ± 2.86) d vs. (19.95 ± 4.33) d, t=6.862] of the observation group were significantly shorter than thosse of the control group( P<0.01). After treatment, the wound longitudinal diameter [(1.89 ± 0.31) cm vs. (2.82 ± 0.54) cm, t=10.666] and wound area [(3.26 ± 0.54) cm 2vs. (4.98 ± 1.10) cm 2, t=10. 024] of the observation group were significantly less than those in the control group ( P<0.01). The serum FN [(2.92 ± 0.50) mg/L vs. (2.45 ± 0.39) mg/L, t=5.293], EGF [(7.03 ± 1.44) μg/L vs. (5.47 ± 1.03) μg/L, t=6.293] of the observation group were significantly higher than those in the control group ( P<0.01). Conclusion:Zhitong-Rusheng Decoction on the basis of conventional treatment on patients after anal fistula operation has a good efficacy, which is conducive to wound healing, reducing clinical symptoms, and improving serum levels of FN and EGF.
