Meta-analysis of efficacy and safety of application of adjuvant materials in the repair of anterior vaginal wall prolapse / 中华全科医师杂志

ABSTRACT

Objective To search the literature of randomized controlled trials on the treatment of anterior vaginal wall prolapse with adjuvant materials and compare the efficacy and safety of anterior vaginal wall prolapse repair with and without adjuvant materials.Methods Searches were made in the databases of Pubmed,Embase and Ovid for randomized controlled trials from 1980 to 2012 on the treatment of anterior vaginal wall prolapse with adjuvant materials.Comprehensive meta-analyses were conducted with Revman 5.1 analysis software to compare vaginal wall anatomy failure rate,operative duration,intraoperative bleeding volume,postoperative visceral injury,pelvic pain,urinary infection,material exposure,material erosion,de novo urinary incontinence and de novo dyspareunia in the adjuvant materials repair and repair without adjuvant materials groups.Results A total of 20 randomized controlled trials including 2313 participants were retrieved.The shortest average follow-up period was 3 months and the longest 36 months.Compared with repair without adjuvant materials,the application of adjuvant materials in anterior vaginal wall repair reduced vaginal front wall prolapse anatomy failure rate lower anatomy failure rate,had a longer operating duration,more peri-operative bleeding and lower urinary tract infection rate.The comprehensive effects were as followsP＜0.01,RR =0.51,95％CI0.41-0.64;P ＜0.01,weighted mean differenece (WMD) =16.25,95％ CI8.07-24.43;P =0.01,WMD =35.00,95％ CI6.90-63.11 ;P =0.03,RR =0.51,95％ CI0.28-0.93,respectively,but the comparison of two groups around in visceral injury,postoperative pain,de novo stress urinary incontinence and de novo dyspareunia had no significant differences (P =0.07,0.58,0.54 and 0.67) and the average materiale exposure and rosion rate were 4.37％ (27/618) and 7.69％ (24/312) respectively.Conclusions The application of adjuvant materials in anterior vaginal wall repair can improve the postoperative recurrence.But no obvious differences exist in the incidence of complications in anterior repair with adjuvant materials and repair without adjuvant materials.
