目的比较阴道超声与腹部超声诊断早期异位妊娠的临床效果。方法选取医院收治的78例疑似早期异位妊娠患者为研究对象,均行阴道超声(TVCDS)及腹部超声(TACDS)检查。比较2种不同诊断方式的准确度、敏感性、特异性及异位妊娠影像学表现检出情况。结果经病理检查证实,78例疑似早期异位妊娠患者中,68例为早期异位妊娠,10例为正常。TVCDS敏感性及准确度均高于TACDS,差异有统计学意义(P<0.05);TVCDS各项异位妊娠影像学表现(附件区团块、盆腔积液、子宫内假孕囊、胚芽反射)检出率均高于TACDS,差异有统计学意义(P<0.05或P<0.01)。结论 TVCDS与TACDS均能有效诊断早期异位妊娠,但与TACDS相比,采用TVCDS可明显提高诊断准确度,且异位妊娠影像学表现检出率较高,值得在临床推广应用。
Objective To compare the clinical effects of vaginal ultrasound and abdominal ultrasound in the diagnosis of early ectopic pregnancy. Methods Totally 78 patients with suspected early ectopic pregnancy admitted to the hospital were enrolled in this study. All patients underwent vaginal ultrasound (TVCDS) and abdominal ultrasonography (TACDS). The accuracy, sensitivity, specificity and detection of ectopic pregnancy imaging were compared between two different diagnostic methods. Results confirmed by pathology, 78 cases of suspected early ectopic pregnancy, 68 cases of early ectopic pregnancy, 10 cases were normal. TVCDS sensitivity and accuracy were higher than TACDS, the difference was statistically significant (P <0.05); TVCDS various ectopic pregnancy imaging findings (annex area lumps, pelvic fluid, intrauterine pseudobags, germ reflex) The detection rate was higher than TACDS, the difference was statistically significant (P <0.05 or P <0.01). Conclusion Both TVCDS and TACDS can effectively diagnose early ectopic pregnancy. However, compared with TACDS, TVCDS can significantly improve the diagnostic accuracy and the detection rate of ectopic pregnancy is high, which is worthy of clinical application.
