Abstract:

Objective

Exploring the effect of staged fumigation and washing on the generation of granulation tissue on the wound of patients after anal fistula surgery.

Methods

120 patients who underwent anal fistula surgery at the Colorectal Department of Chengdu University Affiliated Hospital from January 2022 to November 2023 were selected. Among them,sixty patients were treated with potassium permanganate solution fumigation (control group) and 60 patients were treated with staged formula fumigation (observation group). The clinical data of the two groups of patients were matched 1:1 using propensity score matching method to adjust the balance. Compare the clinical efficacy,wound healing rate,wound pain,edema,secretion scores,granulation tissue generation,and immune and inflammatory related indicators of granulation tissue between two groups of patients. Using Generalized Estimation Equation Modeling (GEE) to analyze the degree and influencing factors of granulation tissue generation in two groups of wounds.

Results

The total effective rates of clinical treatment in the two groups of patients were 100.00% (54/54) in the observation group and 87.04% (47/54) in the control group,respectively. The total effective rate of clinical treatment in the observation group was significantly higher than that in the control group (χ2=7.485,P=0.006). After a comparative study,the wound healing rates of the two groups at 7,14,21,and 28 days after surgery showed a significant increase. There was no significant difference in the wound healing rate between the observation group and the control group at 7 days after surgery (t=0.140,P=0.889). The healing rates at 14 days after surgery (t=2.432,P=0.017),21 days after surgery (t=3.210,P=0.002),and 28 days after surgery (t=4.632,P<0.001) were significantly higher than those in the control group. On postoperative days 3,7,and 14,the wound pain,wound margin edema,and secretion scores in both groups were significantly reduced compared to postoperative day 1,and the degree of reduction in the observation group was significantly better than that in the control group (P<0.05). At the same time,the granulation tissue growth scores of both groups significantly increased on postoperative days 3,7,and 14,with the observation group showing a significantly greater increase than the control group (P<0.05). The expression levels of immune related markers CD86 in granulation tissue of two groups of wounds at 3,7,and 14 days after surgery were significantly reduced compared to 1 day after surgery (P<0.05),while the expression levels of CD206 and CD31 increased(P<0.05). The expression level of inflammation related indicators IL-1β was significantly reduced (P<0.05)compared to postoperative day 1,while the expression levels of VEGF and vWF increased (P<0.05). The improvement in the observation group was better than that in the control group (P<0.05). As observed by GEE,the increase in CD206,CD31,VEGF,and vWF levels and the decrease in CD86 and IL-1β levels in the postoperative wound tissue of the observation group were superior to those of the control group (P<0.05).CD86,CD206,CD31,VEGF,vWF,IL-1β and treatment methods significantly affected the generation of granulation tissue in patients' wounds (P<0.05).

Conclusion

Staged application of formula fumigation and washing has significant therapeutic effects on postoperative anal fistula wounds,promoting wound healing,improving patient symptoms,and also improving the expression levels of CD86,CD206,CD31,IL-1β,VEGF,and vWF in granulation tissue. It is safe and reliable.
