Ease of performance, safety and effectiveness of laparoscopic sterilization techniques are evaluated for 8186 procedures (6995 interval, 680 postabortion and 511 postpartum) performed in Latin America from June 1972 through February 1978. The tubes were occluded via electrocoagulation or application of the spring-loaded clip or the tubal ring. Less than 1% of the procedures were declared technical failures (ie, those which were not completed as planned). For all the tubal occlusion techniques, interval patients had the lowest rate of surgical complications. Pregnancy rates were low for the electrocoagulation and for the tubal ring techniques; patients sterilized by the spring-loaded clip, however, had a significantly higher pregnancy rate.
对1972年6月至1978年2月在拉丁美洲进行的8186例手术（6995例间隔期手术、680例流产后手术和511例产后手术）评估了腹腔镜绝育技术的操作简易性、安全性和有效性。通过电凝、使用弹簧夹或输卵管环来闭塞输卵管。不到1%的手术被判定为技术失败（即未按计划完成的手术）。对于所有输卵管闭塞技术，间隔期手术患者的手术并发症发生率最低。电凝和输卵管环技术的妊娠率较低；然而，使用弹簧夹绝育的患者妊娠率显著较高。
