In September 1972, clinical trials of a spring-loaded clip for laparoscopic sterilization were begun and extended to a number of centers in the United States and overseas. As of March 1974, more than 1000 patients had undergone the procedure, usually performed under local anesthesia in an outpatient setting, with no fixed contraindications. Complications and pregnancy rates based on a preliminary 6-month follow-up are presented. Complications due to application of the clip appeared to be limited to postoperative cramps lasting 24 to 48 hours (26% of the patients). No ectopic pregnancies were reported. Pregnancies, when corrected for unsuspected pregnancies and misapplication of the clip, occurred in 2 of these first 1000 patients. The difficulties and relative contraindications learned from this unselected series and the advantages over electrocagulation techniques are discussed.
1972年9月，一种用于腹腔镜绝育的弹簧夹开始进行临床试验，并扩展到美国和海外的多个中心。截至1974年3月，已有1000多名患者接受了该手术，该手术通常在门诊局部麻醉下进行，没有固定的禁忌症。本文介绍了基于初步6个月随访的并发症和妊娠率。应用夹子引起的并发症似乎仅限于持续24至48小时的术后痉挛（26%的患者）。未报告异位妊娠。在最初的1000名患者中，排除意外妊娠和夹子误用时，有2例发生妊娠。讨论了从这个未经过筛选的系列研究中了解到的困难和相对禁忌症，以及与电凝技术相比的优势。
