Data on 211 consecutive laparoscopic sterilized women were compared. Half the patients were sterilized using unipolar electrocoagulation and the rest had tubal rings. The period of observation was 21-50 months, median 36.5 months. Four failures were observed, median 15 months after the operation. Pregnancy rates were 0.32 per 100 woman years using electrocoagulation and 1.02 using tubal rings. A total of 11% had experienced low abdominal pain and 4% dyspareunia. Menstrual pattern changes were reported by 31% in the electrocoagulation group and 43% in the tubal ring group. The rates of late sequelae were statistically significant independent of the technique employed.
对211例连续接受腹腔镜绝育术的女性的数据进行了比较。一半患者采用单极电凝法进行绝育，其余患者使用输卵管环。观察期为21至50个月，中位数为36.5个月。观察到4例失败，中位时间为术后15个月。采用电凝法的妊娠率为每100妇女年0.32例，使用输卵管环的为1.02例。共有11%的患者经历过下腹部疼痛，4%的患者有性交困难。电凝组有31%、输卵管环组有43%的患者报告有月经模式改变。晚期后遗症的发生率在统计学上具有显著性，与所采用的技术无关。
