目的研究分析异位妊娠早期超声诊断的表现,探索异位妊娠漏诊的相关因素。方法 100例异位妊娠患者,将其随机分为观察组和对照组,每组50例。观察组患者采用阴道超声进行早期诊断,对照组采用腹部超声进行早期诊断,观察分析两组患者的早期超声诊断表现、诊断符合率和漏诊等情况。结果观察组符合46例,符合率为92.0%,包括破裂型23例,未破裂型15例,流产型8例,漏诊率为8.0%(4/50);对照组符合40例,符合率为80.0%,包括破裂型19例,未破裂型14例,流产型7例,漏诊率为20.0%(10/50)。两组符合率比较差异有统计学意义(P<0.05)。结论异位妊娠的早期超声诊断中阴道超声诊断的符合率优于腹部超声,分析其误诊原因,对提高诊断准确率,为进一步的治疗奠定良好基础具有重要的意义。
Objective To analyze the performance of early diagnosis of ectopic pregnancy and explore the related factors of missed diagnosis of ectopic pregnancy. Methods 100 cases of ectopic pregnancy, were randomly divided into observation group and control group, 50 cases in each group. The patients in observation group were diagnosed early by vaginal ultrasound, the control group were diagnosed by abdominal ultrasonography early, and the early ultrasound diagnosis performance, diagnosis coincidence rate and missed diagnosis of the two groups were observed and analyzed. Results The observation group was consistent with 46 cases, the coincidence rate was 92.0%, including 23 cases of rupture, 15 cases of unruptured abortion and 8 cases of abortion. The rate of misdiagnosis was 8.0% (4/50) in control group and 40 cases in control group 80.0%, including 19 cases of rupture, 14 cases of unruptured abortion and 7 cases of abortion. The rate of misdiagnosis was 20.0% (10/50). There was significant difference between the two groups (P <0.05). Conclusion The coincidence rate of diagnosis of vaginal ultrasound in early ultrasonic diagnosis of ectopic pregnancy is better than that of abdominal ultrasound. Analyzing the causes of misdiagnosis is of great significance to improve the diagnostic accuracy and lay a good foundation for further treatment.
