作者报导47例腹腔镜绝育失败再次绝育进行了手术上及病理上的分析研究。切断术绝育失败者大多是自动再吻合或瘘管形成,伞端切断者因为卵巢伞不会移动因而容易再吻合。器械绝育失败由于器械本身有缺陷,安置不正确,或安放于不适当位置。双极电凝法绝育失败者证明组织因电凝而有损伤,但损伤不完全,发现输卵管内膜仍然是存活的。单极电凝绝育发现破坏是完全的,然其失败原因是由于瘘管形成。多数绝育失败是可以预防的,然许多病例没有预防好。
The authors report 47 cases of failure of laparoscopic sterilization and sterilization again for surgical and pathological analysis. Most of the failure of the surgical resection sterilization is automatic re-fistula or fistula formation, the umbrella-side cut off because the ovary umbrella will not move easily re-coincidence. Failure to Sterilize Instruments Due to defects in the device itself, incorrect placement, or placement in an improper position. Bipolar coagulation failure of sterilization showed that tissue damage due to electrocoagulation, but the damage is not complete and found that the fallopian tube intima is still alive. Unipolar coagulation sterilization found that the destruction is complete, but its failure is due to fistula formation. Most sterilization failures can be prevented, but many cases are not preventable.
