摘要
目的:本研究旨在了解子宫内膜三线型和厚度在异位妊娠诊断中的作用。方法:回顾性分析疑为异位妊娠病人的临床资料和超声表现,检验子宫内膜三线型和厚度在异位妊娠诊断中的预测作用。结果:三线型有94.8%的特异性和38.1%的敏感性(487例),异位妊娠病人的平均内膜厚度较正常妊娠者薄(9.5±5.7mmVS12.5±5.9mmP<0.05)。正常妊娠和早期流产病人子宫内膜厚度相似(12.5±5.9mmVS12.4±5.6mm)。接受操作曲线显示子宫内膜厚度对于异位妊娠诊断无使用价值。结论:三线型对异位妊娠诊断有特异性,但敏感性低,异位妊娠病人子宫内膜趋向于较薄。
Objective:The purpose of this study was to examine the usefulness of the endometrial trilaminar pattem and thickness in the diagnosis of ectopic pregnancy. Methods: We reviewed patient records for clinical and ultrasonographic data for patients with the suspicion of ectopic pregnancy. The trilaminar pattern and endometrial thickness were test as predictors for the diagnosis of ectopic pregnancy. Results: The trilaminar patten had a specificity of 94.8 % and sensitivity of 38.1% ( n = 487 women). The mean endometrial thickness was thinner in patients with ectopic, compared with normal pregnancy (9.5 ± 5.7mm vs 12.5±5.9mm; P 〈 0.05). Patients with normal pregnancy or first- trimester losses had comparable thicknesses (12.5 ± 5.9mm vs 12.4± 5.6mm). The receiver operator curve showed that there was no thickness value useful for the diagnosis of ectopic pregnancy. Conclusion: The trilaminar pattern is specific for the diagnosis of ectopic pregnancy, but it is associated with low sensitivity. The endometrial thickness tends to be thinner in patients with an ectopic pregnancy.
