经直肠超声在妇科疾病诊断中的价值

Value of transrectal ultrasonography in diagnosing gynecological diseases

目的:探索经直肠超声(TRS)技术在妇科疾病诊断中的价值,并与经腹超声(TAS)及经阴道超声(TVS)技术进行比较。方法:随机抽取87例无性生活史妇科疾病患者行TAS检查,同时采用阴式腔内探头行TRS检查。另外,随机抽取54例妇科疾病患者仅行TVS检查。比较TRS、TAS、TVS3种技术的显像差异。对行TRS和TAS检查的87例患者进行随访,并比较TRS、TAS技术的诊断符合率。结果:TRS技术在以子宫和卵巢为中心的近场图像的细微显影分辨能力,明显优于TAS技术(P<0.01),其对无性生活史女性的妇科疾病诊断符合率(88.14%)明显高于TAS技术(42.37%),P<0.001。TRS与TVS技术,两者的轮廓显影及组织细微显影能力均无显著性差异(P>0.05),TRS在妇科细微显影能力上与TVS技术具有相似的效果。结论:TRS作为妇科可选择的超声技术之一,对子宫和卵巢具有良好的显影分辨能力,更适用于需要提供细微图像数据但无性生活史的妇科疾病患者。

Objective：To study the application value of transrectal ultrasonography（TRS） in diagnosing gynecological diseases and compare TRS technique with transabdominal ultrasonography（TAS） and transvaginal ultrasonography（TVS） technique.Methods：Eighty-seven gynecological patients without sex life history were selected randomly.They received TAS exam and following TRS exam with transvaginal intracavitary probe.Fifty-four gynecological patients were selected to receive TVS exam only.We compared TRS with TAS and TVS to explore the differences of visualization.Diagnostic accordance rate of TRS were compared with that of TAS in 87 patients by follow-up visiting.Results：The detailed visualizing ability in near field（uterus/ovary-center） of TRS was better than TAS significantly（P0.01）.For female patients without sex life history, total diagnostic accordance rate of TRS was higher than that of TAS significantly（88.14% vs.42.37%, P0.001）.There were no significant differences of outline and detailed visualizing abilities between TRS and TVS（P0.05）.TRS and TVS had similar effects in gynecological detailed visualizing abilities.Conclusion：TRS, which can be taken as a selection of ultrasonography technique in diagnosing gynecological diseases, has outstanding detailed visualizing abilities for uterus and ovaries.It is more appropriate for the gynecological patients without sex life history and need detailed visualizing data.
