In tubal sterilization operations with a plastic clip failures with subsequent pregnancies become only known by misplacement of the clips. Failures are more frequent when the clips are placed through a posterior colpotomy. In 163 laparoscopic tubal sterilization with the Tuplar-clip during the last 2 1/2 years no subsequent pregnancy was observed. The carbon-dioxide pertubation or the chromo-pertubation after occlusion of the tubes with a clip permits an immediate intra-operative proof of secure bilateral tubal occlusion. A pregnancy due to faulty placement of the clip is then no longer possible. Other advantages of this method of tubal sterilization are mentioned.
在使用塑料夹进行输卵管绝育手术时，术后怀孕失败仅因夹子放置不当才为人所知。通过后穹窿切开术放置夹子时，失败情况更为常见。在过去两年半的时间里，进行了163例使用Tuplar夹的腹腔镜输卵管绝育手术，未观察到术后怀孕情况。在用夹子闭塞输卵管后进行二氧化碳通气或染色通气，可在术中立即证实双侧输卵管闭塞可靠。这样就不可能因夹子放置不当而导致怀孕。文中还提到了这种输卵管绝育方法的其他优点。
