本文报告用显微手术对70例绝育后妇女进行输卵管再通术。随访2～6年,有61例宫内妊娠,占87.1％;58例已足月分娩,占82.9％。流产2例,(2.85％);1例人工流产,无宫外孕。腹部切口较小,减少暴露腹腔内组织及用无创伤8-0尼龙线穿过粘膜缝合,成功率较高。发现绝育术与再通术问隔时间超过5年者,成功率明显下降(P<0.01)。用Pomeroy法绝育作映部对映部吻合术14例全部足月分娩,达100％。在绝育术时,如能注意结扎部位及操作技术,能增加再通术的成功率。
This article reports the use of microsurgery in 70 cases of post-tubal recanalization of women after sterilization. Followed up for 2 to 6 years, 61 cases of intrauterine pregnancy, accounting for 87.1%; 58 cases have full-term delivery, accounting for 82.9%. Abortion in 2 cases, (2.85%); 1 case of abortion, no ectopic pregnancy. A smaller incision in the abdomen reduces the exposure of the peritoneal tissue and the non-invasive 8-0 nylon thread through the mucosal suture, a higher success rate. Found that sterilization and recanalization asked interval of more than 5 years, the success rate decreased significantly (P <0.01). Pomeroy sterilization method used as part of the albumen anastomosis in 14 cases of full term delivery, up to 100%. In sterilization, such as attention to the site of ligation and operation techniques, can increase the success rate of recanalization.
