70 women were examined by transvaginal scanning after a pelvic gynecological examination revealed the suspicion of an ectopic pregnancy. In 32 cases a pelviscopy confirmed an extrauterine pregnancy, 29 of those were detected previously by transvaginal scanning. In 29 other patients the suspected diagnosis could be excluded. In 7 women the suspicion of an ectopic pregnancy could neither be confirmed nor excluded by means of transvaginal scanning. However, in those cases controls of beta-HCG presented values less than 5 mU/ml pleading for the non-existance of pregnancy. From the total number of patients examined 10 cases turned out to provide false results, this is equivalent to a failure rate of 13.1%. Transvaginal scanning is a powerful diagnostic tool to detect ectopic pregnancies, potentially helping to avoid the procedure of a pelviscopy in a number of cases.
70名女性在盆腔妇科检查怀疑宫外孕后接受了经阴道扫描检查。32例经盆腔镜检查确诊为宫外妊娠，其中29例此前经阴道扫描检测出。另外29例患者排除了疑似诊断。7例女性经阴道扫描既不能确诊也不能排除宫外孕怀疑。然而，在这些病例中，β-HCG检测值低于5 mU/ml，表明未怀孕。在接受检查的患者总数中，有10例结果为假，这相当于失败率为13.1%。经阴道扫描是检测宫外孕的有力诊断工具，有可能在许多情况下避免盆腔镜检查。
