RESUMO
Objective To research the effect of Huang Bai capsules combined with Chinese medicine fumigation on treatment of chronic anal fissure.Methods 84 patients with chronic anal fissure from the second hospital of Shandong from January 2014～June 2016 were divided into two groups randomly.The control group was treated with Nitroglycerin and Lining gel and the observation group was treated with Huang Bai capsules combined with Chinese medicine fumigation.Treatment efficacy,symptom improvement,VAS score,gap healing time,ARP and RRP were compared between the two groups.Results The total effective rate in the observation group 95.24％is higher than that in the control group 78.57％(P<0.05).The proportion of bleeding and constipation after treatmen were lower than that before treatment(P<0.05).The proportion of bleeding and constipation in the observation group(9.52％and 11.90％)were lower than those in the control group(28.57％and 33.33％)(P<0.05).③ VAS score and gap healing time in the observation group were(1.18±0.20)points and(14.92±2.05)days,which were better than those in the control group(2.39±0.22)points and(19.16±2.28)days(P<0.05).④ARP and RRP in the observation group were(7.88±0.40)kPa and(2.61±0.31)kPa,which were lower than those in the control group(8.59±0.55)kPa and(3.09±0.45)kPa(P<0.05).Conclusion It can speed up crack healing and improve the effect of patients with anal fissure which Huang Bai capsules combined with Chinese medicine fumigation were used in the treatment.
