目的通过B型超声及清宫送病理两种不同方法检测药物流产后阴道出血时间延长患者宫腔内残留组织,探讨米非司酮药物流产后阴道出血时间延长与残留组织(蜕膜/绒毛)的关系。方法对2011年6月-12月144例药物流产后出血患者根据出血时间是否延长(>15 d),从B型超声情况及清宫病理情况分别研究。结果 B型超声提示:出血时间≤15 d的96例患者中20例有宫腔残留物,出血时间>15 d的48例患者中20例有宫腔残留物,两组比较,差异有统计学意义(P<0.05)。清宫病理提示:出血≤15 d与出血>15 d宫腔残留组织病理构成比较差异无统计学意义(P>0.05)。结论药物流产后阴道出血时间延长与宫腔残留有关,与残留组织是否为绒毛或蜕膜无关。
OBJECTIVE: To detect residual intrauterine tissue after prolonged vaginal bleeding after medical abortion by two different methods of B-mode ultrasonography and biopsy, and to explore the relationship between prolonged vaginal bleeding and residual tissue (decidua / villi) after mifepristone abortion relationship. Methods From June to December in 2011, 144 patients with post-abortion bleeding were studied according to whether the bleeding time was prolonged (> 15 d) and the type B ultrasound and pathological changes of the pathological changes of the h? Results Type B ultrasound showed that in 20 of 96 patients with hemorrhage ≤15 days, there were 20 cases with uterine cavity residue and 20 cases with uterine cavity residue in hemorrhage time> 15 days. The differences between the two groups were statistically significant Significance (P <0.05). Histopathology showed that there was no significant difference in the histopathological features of residual tissue in the uterine cavity after 15 days of hemorrhage and 15 days of hemorrhage (P> 0.05). Conclusion The prolonged vaginal bleeding after medical abortion is related to the residual uterine cavity, regardless of whether the residual tissue is villus or decidua.
