【摘要】 目的 探讨避免宫外孕误诊的方法。 方法 71例临床臆断为早期异位妊娠者经阴道彩色多普勒(transvaginal sonography color Doppler，TVS-CD)协诊，后行腹腔镜手术确诊，术前诊断与手术结果对照分析。 结果 腹腔镜证实为异位妊娠65例(诊断符合率91.5%)，其中45例异位妊娠包块<2cm，漏诊、误诊6例。 结论 TVS-CD临床应用价值在于诊断早期异位妊娠，发现临床症状不典型、经腹部超声(TAS)未发现或不能确定的早期异位妊娠包块，是诊断早期异位妊娠的首选诊断方法，但仍有漏诊与误诊病例。腹腔镜结果反馈术前诊断信息，分析漏诊误诊原因，进一步提高了异位妊娠早期诊断率。
