To assess the clinical effects and safety of the Biantong Capsules and Qirong Runchang Oral Liquid in the treatment of panhysterectomy postoperative constipation.Methods:A total of 112 cases who were admitted and received the panhysterectomy were randomly divided into two groups,with 56 cases in each group.The treatment group of patients were treated with Biantong Capsules,while patients in the control group were treated with Qirong Runchang Oral Liquid.First defecation time,length of hospital stay,recurrence and safety of constipation 1 month,2 months and 3 months after drug withdrawal were recorded.Results:4 patients in the control group terminated the test in advance due to ineffective treatment after 72 hours of treatment.The first defecation time in the treatment group was 0.48 day early than that in the control group（P<0.05); and the hospitalization time of the treatment group was significantly 0.22 day shorter than that of the control group (P<0.05).The recurrence rate of the treatment group was significantly lower than that of the control group 2 months and 3 months after drug withdrawal (P<0.05).The adverse effects rate of the two groups was low and there was no significant difference between the two groups.Conclusion:Biantong Capsules in treatment of panhysterectomy postoperative constipation have rapid effects and good safety,shorten the hospitalization time,reduce the recurrence rate worthy of promotion,which was worthy of clinical promotion.
