Commonly used suture materials and techniques for perineal repair following vaginal delivery were compared in a randomized controlled trial involving 1574 women. Three comparisons were made using a modified factorial design. In the comparison of teflon-coated polyglycolic acid (Dexon plus) with chromic catgut for repair of the vagina and deep perineal tissues there was no clear difference other than less short-term analgesia being required in association with polyglycolic acid. Outcome was also similar after skin repair with either polyglycolic acid or chromic catgut or silk, although silk repair required more packets of material and was associated with delay in resuming sexual intercourse; polyglycolic acid was more likely to need removal than chromic catgut but it appeared to reduce the need for resuturing. There was no clear difference between continuous subcuticular and interrupted transcutaneous sutures for repair of perineal skin.
在一项纳入1574名女性的随机对照试验中，对阴道分娩后会阴修复常用的缝合材料和技术进行了比较。采用改良析因设计进行了三项比较。在比较聚乙醇酸涂层聚乙醇酸（Dexon plus）和铬制肠线用于阴道和会阴深部组织修复时，除了聚乙醇酸所需的短期镇痛较少外，没有明显差异。用聚乙醇酸、铬制肠线或丝线进行皮肤修复后的结果也相似，尽管丝线修复需要更多的材料包，并且与恢复性交延迟有关；聚乙醇酸比铬制肠线更有可能需要拆除，但它似乎减少了再次缝合的需要。会阴皮肤修复采用连续皮下缝合和间断经皮缝合之间没有明显差异。
