输卵管结扎术后异位妊娠相关因素分析

Analysis on Related Factors of Ectopic Pregnancy after Tubal Ligation

目的：探讨输卵管结扎术后异住妊娠的相关因素。方法：对73例输卵管结扎术后异位妊娠临床资料进行回顾性分析。结果：输卵管结扎术后发生的异位妊娠均为输卵管妊娠，以31-35岁为发病年龄高峰，术后0．5-3年为高发时间，结扎方法则以折叠结扎切断法发病率最高，抽芯包埋法最低。结论：输卵管结扎术后异位妊娠与输卵管结扎术式、手术时机有关，结扎时采用抽芯包埋法相对安全可行。

Objective：To study the related factors of ectopic pregnancy after tubal ligation. Methods：The clinical data of 73 patients of ectopic pregnancy after tubal ligation were analysed retrospectively. Results：Ectopic pregnancies after surgical ligation were all tubal pregnancies, with the high incidence time between half a year to 3 years postoperation among the women between the age of 31 and 35. And the incidence rate is the highest in Pomeroy＇s technique, while the lowest is the imbedding of the pericardium. Conclusion：The ectopic pregnancy after tubal ligation is related to the methods and timing of tubal ligation. It is safe and feasible to adopt imbedding of the pericardium at the time of tubal ligation.
