The spring-loaded clip and the tubal ring techniques of laparoscopic female sterilization are compared for ease of performance, safety and effectiveness at the Kandang Kerbau Hospital in Singapore. The two techniques were randomly assigned to 299 postpartum patients and 300 postabortion patients. The assigned procedure could not be performed for two of the ring cases and three of the clip cases. Bleeding and equipment problems made laparotomy necessary in two clip cases and equipment problems caused a change in technique in the other clip case. Hydrosalpinx and adhesions were responsible for a change to laparotomy in the two ring cases. Surgical difficulties, chiefly the result of equipment problems, were significantly higher for both postpartum and postabortion clip procedures. Complications and complaints reported immediately after surgery and at the 7- to 21-day follow-up visit were low for all four groups. For both postabortion and postpartum patients, six- and 12-month data show that pregnancy rates are significantly higher for patients sterilized with the clip than with tubal rings.
在新加坡康 dang 葛宝医院，对弹簧夹法和输卵管环法这两种腹腔镜女性绝育技术进行了比较，评估其操作简便性、安全性和有效性。这两种技术被随机分配给 299 名产后患者和 300 名堕胎后患者。在使用输卵管环的病例中有 2 例以及使用弹簧夹的病例中有 3 例无法进行指定手术。在 2 例使用弹簧夹的病例中，出血和设备问题导致必须进行剖腹手术，在另 1 例使用弹簧夹的病例中，设备问题导致手术技术改变。在 2 例使用输卵管环的病例中，输卵管积水和粘连导致改为剖腹手术。对于产后和堕胎后使用弹簧夹的手术，主要由于设备问题导致的手术困难显著更高。在所有四组中，术后立即以及在 7 至 21 天随访时报告的并发症和不适情况都较少。对于堕胎后和产后患者，6 个月和 12 个月的数据显示，使用弹簧夹绝育的患者妊娠率显著高于使用输卵管环绝育的患者。
