| Background: Due to the high incidence of mixed hemorrhoids,most patients who fail to respond to conservative treatment often require surgical intervention.How to reduce postoperative complications,shorten the course of disease,improve the quality of life of patients after surgery,and promote wound healing is the pursuit of clinical anorectal doctors.As a key factor affecting wound healing,postoperative incision dressing change is very important for wound healing after mixed hemorrhoids.At present,there are many controversies about the number of postoperative incision dressing change for patients with mixed hemorrhoids in anorectal clinic,and there is no unified international standard on the number of postoperative incision dressing change.Objective: To explore the influence of different times of dressing change on wound healing after external stripping and internal ligation of mixed hemorrhoids,and to seek a more reasonable times of dressing change,so as to provide reference for future anorectal clinical dressing change in anorectal diseases after surgery.Methods: Select sep 2019-October 2020 in the first affiliated hospital of guangxi medical university fairy assembles CGMH anorectal surgery line within the mixed hemorrhoid external strip of 90 cases of patients with surgery,were randomly divided into three groups: in clinic order or once-daily treatment group(QD),2 times daily treatment group(BID)and treatment group(dar)3 times a day,each 30 cases in each group.All patients underwent different times of dressing change according to different grouping(dressing supplies,drugs and operation methods of dressing change were the same).The pain,bleeding and edema of the three groups on the 1st,3rd and5 th day after operation were observed and recorded.The total number of days in hospital after the operation(from the day of operation to the day of discharge);And the incidence of other complications during hospitalization;The outpatient visit was conducted weekly after discharge,and the granulation growth on the wound surface was observed and recorded on the 5th,14 th and 21 st day after operation.The overall outcome was assessed on the 14 th and 30 th postoperative days.Results:(1)Overall efficacy: On the 14 th day after surgery,there was no statistical significance in the overall postoperative efficacy among the three groups(P > 0.05).On the 30 th day after surgery,there was a statistically significant difference in the overall efficacy of the three groups(P<0.05),and the overall efficacy of the BID group was more significant than that of the QD group and the TID group(P<0.05).(2)Pain degree: On the first day after surgery,there was no statistical significance in pain degree among the three groups(P > 0.05).On the 3rd and 5th day after surgery,there was statistically significant difference in pain degree among the three groups(P < 0.05),and the pain relief degree in the BID group was more significant than that in the QD group and the TID group on the 3rd and 5th day after surgery(P <0.05).(3)Bleeding(oozing): On the 1st,3rd and 5th day after surgery,there was no statistical significance in the bleeding(oozing)among the three groups(P > 0.05).(4)Degree of edema: On the 1st,3rd and 5th day after surgery,the degree of edema was found in the three groups,with no statistical significance(P > 0.05).(5)Granulation growth: On the 5th and 14 th day after surgery,there was no statistical significance in granulation growth among the three groups(P > 0.05).On the 21 st day after surgery,there was a statistically significant difference in granulation growth among the three groups(P <0.05),and the degree of granulation growth in the BID group was more significant than that in the QD group and the TID group on the 21 st day after surgery.(6)Postoperative hospitalization time: QD group(6.30±1.84)days,BID group(5.27±1.55)days,TID group(6.40±1.87)days.Compared with QD and TID groups,BID group was more significant in shortening the length of hospital stay(P<0.05).(7)Other complications: There was no statistical significance in the incidence of other complications among the three groups during hospitalization(P > 0.05).Conclusion(s):(1)Dressing change twice a day after surgery was superior to the other two groups in alleviating anal pain,shortening the length of hospital stay and promoting the growth of wound granulation.(2)There was no significant correlation between the number of dressing changes and postoperative wound bleeding and early edema resolution.(3)Dressing change twice a day after surgery is more conducive to postoperative wound healing and worthy of clinical promotion. |
