超声检查成人正常阑尾的方法探讨

Exploration of normal appendix in adults by ultrasonography

目的探讨超声检查成人正常阑尾最佳的扫查方法。方法将194例既往无右下腹痛,无阑尾炎病史的健康成人随机分成三组进行超声检查比较超声探头回盲瓣顺时针转向移动法(回盲瓣顺时针转向法)、右侧腹纵横切升结肠盲肠法(盲肠纵横切法)和右下腹麦氏点任意扫查法(麦氏点任意法)对正常阑尾的显示率。对未能显示阑尾者采用上述三种方法联合应用寻找阑尾。结果回盲瓣顺时针转向法、盲肠纵横切法和麦氏点任意法对正常阑尾的显示率分别为90.8%、83.1%和79.7%,前者与后两者显示率分别比较差异有统计学意义(P<0.05)三种方法联合应用使正常阑尾总显示率达到97.9%。结论回盲瓣顺时针转向法对正常阑尾显示率优于盲肠纵横切法和麦氏点任意法联合应用使正常阑尾显示率进一步提高。

Objective To explore the best scanning nlethod for normal appendix in adults by ultrasonography. Methods One hundred and ninety - four cases with normal appendix were divided into three groups： ileocecal valve clockwise rotary scanning group, caecum anti- clockwise rotary scanning group and McBurney＇ s random scanning group, then they were examined by tdtrasonography, and the detection rate was compared. In each group, the cases with appendix undetected were detected with the combined techniques. Results The detection rate of normal appendix was 90.8 %, 83.1% and 79.7 % for ileocecal valve clockwise rotary scanning group, caecum anti - clockwise rotary scanning group and McBurney＇ s random scanning group respectively. There was significant difference between ileocecal valve clockwise rotary scanning group and caecum anticlockwise rotary scanning group or McBurney＇s random scanning group （P 〈 0.05）. And the total detection rate of normal appendix in adults was 97.9% for the combined techniques. Conclusion The ileocecal valve clockwise rotary scanning is superior to caecum anti - clockwise rotary scanning and McBurnaey＇ s random scanning in detecting the normal appendix, while the combined techniques improve the detection rate of normal appendix in adults.
