A randomized investigation of bipolar electrocoagulation (BE) and endocoagulation (EK) was undertaken. The material was examined two years after the intervention with the object of revealing possible late complications. No significant differences were found between the two techniques. In the entire material, 97.4% were satisfied with the intervention performed and 1.3% had regretted sterilization. In approximately 40% pain of one sort or another related to the abdomen/genitalia and/or to menstruation occurred. The distribution among the groups was lower than in other materials. In 40% (EK) and 60% (BE) changes in menstrual bleeding occurred while 40% in both of the groups had developed one or other form of menopausal symptoms. In the BE-group, two women had intrauterine pregnancies as compared with no pregnancies in the EK-group.
开展了一项关于双极电凝术（BE）和内膜电凝术（EK）的随机调查。干预两年后对材料进行检查，目的是发现可能的晚期并发症。两种技术之间未发现显著差异。在整个材料中，97.4%的人对所进行的干预感到满意，1.3%的人后悔进行了绝育。约40%的人出现了与腹部/生殖器和/或月经相关的某种疼痛。各组中的发生率低于其他材料。在40%（EK）和60%（BE）的病例中出现了月经出血变化，而两组中40%的人出现了某种形式的更年期症状。在BE组中，有两名妇女发生了宫内妊娠，而EK组中没有妊娠情况。
