阴道B超及腹部B超对异位妊娠临床诊断的对比研究

Comparative study of vaginal B-mode ultrasonography and abdominal B-made ultrasonography in clinical diagnosis of ectopic pregnancy

目的研究腹部B超及阴道B超诊断异位妊娠的临床价值。方法选取经手术或病理检查确诊的异位妊娠患者168例,分为腹部B超组、阴道B超组、腹部和阴道B超联合检查组,并进行回顾性分析,比较诊断准确率。结果腹部B超诊断符合率为89.29%,阴道B超符合率为94.92%,腹部与阴道B超联合检查符合率为98.11%;差异有显著意义;阴道B超最早发现宫外类孕囊影在停经32 d时,阴道B超发现宫外类孕囊影的平均停经天数为(36±2.2)d,腹部B超发现宫外类孕囊影的平均停经天数为(41±4.3)d,差异有显著意义。结论阴道B超结合腹部B超诊断异位妊娠临床符合率高,阴道B超声对宫外孕的早期诊断有重要的价值。

Objective To study the clinical value of abdominal B ultrasound examination and vaginal B ultrasound ex- amination in the diagnosis of ectopic pregnancy. Methods A total of 168 patients diagnosed with ectopic pregnancy by surgery or pathological examination were selected and randomly divided into the abdomihal B ultrasound group, the vaginal B ultrasound and the abdominal and vaginal B ultrasound joint inspection group. All the patients were analyzed retrospectively and their diagnosis accuracy rates were compared. Results The diagnostic accordance rate of abdominal B ultrasound scan was 89.29%, vaginal B ultrasound scan 94.92%, and abdominal and vaginal B ultrasound scan joint inspection 98.11%, with statistically significant difference. Vaginal B ultrasound found ectopic pregnancy sac shadow first on the 32 days of menolipsis; Vaginal B ultrasound found ectopic pregnancy sac shadow on the （36±2.2） days of menolipsis averagely; Abdominal B ultrasound found ectopic pregnancy sac shadow on the （41±4.3） days of menolipsis averagely, with statistically significant difference. Conclusion Vaginal B ultrasound combined with abdominal B ultrasound shows high clinical accordance rate in the diagnosis of ectopic pregnancy. Vaginal B ultrasound is of important value for the early diagnosis of ectopic pregnancy.
