A randomized, prospective trial was designed to compare direct trocar insertion with prior peritoneal insufflation with a Verres needle for laparoscopic tubal sterilization. Direct trocar insertion resulted in fewer instrument insertions (21.8% vs. 7.8%) and use of smaller volumes of CO2 (2.67 vs. 2.32 L). Direct trocar use resulted in a decrease in operating time from 9 minutes, 40 seconds in the needle group to 7 minutes, 30 seconds in the trocar group. Minor omental injuries occurred in a small percentage of each group, while serious complications occurred once in each group.
一项随机前瞻性试验旨在比较腹腔镜输卵管绝育术中直接套管针插入与先用Verres针进行腹腔充气后插入的效果。直接套管针插入减少了器械插入次数（21.8%对7.8%），并减少了二氧化碳使用量（2.67升对2.32升）。使用直接套管针使手术时间从针组的9分40秒减少到套管针组的7分30秒。每组均有一小部分出现轻微网膜损伤，每组各有1例出现严重并发症。
