To observe clinical effect of Kangfuxin liquid to promoting postoperative wound healing of catheter drainage with high anal abscess.

Sixty patients of high perianal abscess hospitalized in Shanghai Changning Tianshan Hospital of Traditional from July 2015 to June 2017 were divided into treatment group and control group according to the digital random table method. Both of the two groups were treated by the catheter drainage. The treatment group use Kangfuxin liquid to wash abscess cavity from the 2nd day after operation while the control group use metronidazole liquid. Compare the extubation time, wound healing time,anal pain and exudation in the 3rd, 7th, 14th day after operation, the total effective rate after one month, the recurrence rate and the rate of anal fistula formation after six months.

The treatment group need less extubation time (t=3.506, P=0.001) and wound healing time (t=-6.64, P<0.001) than the control group, with statistically significant differences. The scores of anal pain (H=0.182, P=0.670) and exudation(H=0.001, P=0.973) in the 3rd day after operation has no significant difference. The pain scores (H=4.480, P=0.034; H=4.516, P=0.034) and the exudation scores (H=5.263, P=0.022; H=4.345, P=0.037) of the treatment group are less than the control group after the 7th, 14th day after operation, with statistically significant differences. The total effective rate after one month of the treatment group (93.3%) was significantly higher than that of the control group (73.3%) (χ²=4.320, P<0.05). Followed up for six months, both of the two groups has one case recurrent perianal abscess, with no significant differences (χ²=0.000, P>0.05), and the anal fistula formation in the treatment group (6.7%) is much less than the control group (30%) with significant differences (χ²=5.455, P<0.05).

Kangfuxin liquid can promote postoperative wound healing of catheter drainage with high anal abscess, produce anal pain and exudation. It is validity and worthy of clinic application.
