| 目的 探讨影响经阴道超声(TVS)诊断早期异位妊娠(EP)准确率的因素。方法 回顾性分析5600例停经4~6周患者中205例疑似EP的声像图,并与腹腔镜结果对照。结果 TVS诊断早期EP准确率为68.86%(115/167);妊娠位置不确定(PUL)发生率38.54%(79/205);早期妊娠无明显临床症状比例为53.66%(110/205);未破裂型EP包块中输卵管环型居多(110/155,70.97%);年资短的医师较年资长的医师易发生误诊(P<0.05)。结论 影响TVS诊断早期EP的主要因素为PUL的存在、缺乏临床症状、未破裂EP超声图像不典型及超声医师的经验和技能。 |

| Objective To explore the factors affecting the accuracy rate of transvaginal ultrasonography (TVS) in diagnosis of the early ectopic pregnancy (EP). Methods The TVS features of 205 cases of 5600 suspected EP patients who had postmenopaused 4—6 weeks were analyzed, and the results were compared with that of laparoscopy. Results The accurate rate of TVS in diagnosis of EP was 68.86% (115/167); The incidence of pregnancy of unknown location (PUL) was 38.54% (79/205). The proportion of patients who had no obvious clinical symptoms in the early pregnancy was 53.66% (110/205). The unruptured EP mainly appeared as tube ring mass (110/155, 70.97%) on ultrasonography. The less experienced physicians were more easy to misdiagnosis than the experienced physicians (P<0.05). Conclusion The main factors affecting the accuracy rate of TVS in the early diagnosis of EP is the existence of PUL, the lack of clinical symptoms, the unruptured EP atypical ultrasound images and the experience and skills of ultrasound doctors. |
