Abstract:〔Abstract〕 Objective To investigate the clinical effect of Kubai lotion combined with mometasone furoate cream in the treatment of Ⅲ ~ Ⅳ hemorrhoids complicated with anal eczema. Methods A total of 100 patients with stage Ⅲ ~ Ⅳ hemorrhoids complicated with anal eczema admitted to the 7th People's Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from September 2018 to August 2019 were selected and divided into a control group and an observation group according to random number table method, with 50 cases in each group. The observation group was fumigated with Kubai lotion and coated with mometasone furoate ointment after surgery, the control group was fumigated with hemorrhoidal disease washing solution and coated with mometasone furoate ointment. The total effective rate, anal edema and pain at day 1, 3, 7 and 14 after surgery, the degree and frequency of anal pruritus before surgery and on day 7 after surgery were compared between the two groups. Results There was no significant difference in the total effective rate between the two groups (P > 0.05). There was no significant difference in edema score between the two groups on day 1 and day 3 after surgery (P > 0.05). The edema score of the observation group was lower than that of the control group on the 7th and 14th day after surgery, and the difference was statistically significant (P < 0.05). In both groups, the degree of edema peaked on the 7th day after surgery, and then began to improve. There was no significant difference in visual analog scale (VAS) scores between the two groups on day 1 after surgery (P > 0.05). The VAS scores of the observation group were lower than those of the control group on day 3, 7 and 14 after surgery, and the differences were statistically significant (P < 0.05). The VAS scores of the two groups reached the peak on the 7th day after surgery and then began to improve again. After treatment, the itching frequency and degree scores of the two groups were decreased to varying degrees, and after treatment, the itching frequency and degree scores of the observation group were lower than those of the control group, the differences were statistically significant (P < 0.05). Conclusion Kuobei lotion combined with mometasone furoate cream can effectively reduce the pain and edema symptoms of patients after the operation of hemorrhoids in stage Ⅲ ~ Ⅳ complicated with anal eczema, and has a good effect on the treatment of perianal pruritus.
