Jugosl Ginekol Opstet. 1980 May-Aug;20(3-4):140-5.
From 1978 to April 1980, 36 laparoscopic sterilization procedures were completed at the Gynecological Department in Maribor. For tubal occlusion in 16 cases Tupla clips and in 20 cases the Tubal Falope ring were used. It appears that the incidence of complications and other technical difficulties is somewhat more frequent with clips. There have been no pregnancies in all these cases.
1978年至1980年4月期间，马里博尔妇科完成了36例腹腔镜绝育手术。其中16例使用Tupla夹进行输卵管闭塞，20例使用输卵管法洛皮环。似乎使用夹子时并发症和其他技术困难的发生率略高一些。所有这些病例均未怀孕。
