目的探讨输卵管结扎术后异位妊娠发生的相关因素。方法对44例输卵管结扎术后异位妊娠的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31-40岁为发病年龄高峰。术后4-6年为高发时间,结扎方法以结扎切除法发病率最高,抽芯近端包埋法最安全。结论输卵管结扎术后异位妊娠的发生与输卵管结扎术式,手术时机,手术部位有关。结扎时采用峡部抽芯包埋法相对安全。
Objective To investigate the related factors of ectopic pregnancy after tubal ligation. Methods The clinical data of 44 patients with tubal ligation after ectopic pregnancy were analyzed retrospectively. Results tubal ectopic pregnancy occurred after tubal pregnancy are tubal, age at onset of 31-40 years of age. 4 to 6 years after the high incidence of time, the ligation of the ligation method the highest incidence of incision, retraction proximal embedding most safe. Conclusions The incidence of ectopic pregnancy after tubal ligation is related to tubal ligation, operation timing and surgical site. Ligation isthmus embedding method is relatively safe.
