摘要
目的探讨高频彩色多普勒超声(高频彩超)在诊断老年性腹股沟疝中的价值。方法回顾性分析80例老年性腹股沟疝的高频彩超检查的影像资料,观察疝囊内容物及血流显示,并结合临床按照疝囊颈部内径对腹股沟疝进行分型描述。结果以腹壁下动脉作为标志,确定腹壁下动脉与疝囊颈的关系,鉴别腹股沟的斜疝、直疝。腹股沟疝的声像表现:在腹股沟区探及由疝囊和内容物组成的混合性包块回声,疝囊口与腹腔相通,当内容物为肠管可表现为肠管壁、肠腔气体及肠腔内容物回声;当内容物为大网膜时可表现为簇状杂乱回声团或筛网状回声光团。疝囊内容物彩色多普勒血流显示:易复性疝显示红、蓝条状或点状较多血流信号;难复性和嵌顿疝血流显示减少,呈散在棒状或星点状血流信号;绞窄性疝显示无血流或少许星点状血流信号。结论高频彩超可作为老年性腹股沟疝诊断的首选检查方法。
Objective To investigate the value of high-frequency color Doppler ultrasound in the diagnosis of inguinal hernia in senile men.Methods Image data of high-frequency color Doppler ultrasound examination were analyzed retrospectively in 80 elderly patients with inguinal hernia,and hernial contents and blood flow were observed.The hernia was classified according to the diameter of internal hernial ring and the clinical symptoms.Results Considering the inferior epigastric artery as a reference,the relation between inferior epigastric artery and hernia sac neck was revealed,and direct and indirect inguinal hernias were identified.On ultrasound images,inguinal hernia was represented by echoes of hernial sac and contents in the inguinal region.Since hernial sac opening was connected to abdominal cavity,when the contents were intestine,the intestine walls,gas and the other contents produced ultrasound echoes.When the contents were the great omentum,inguinal hernia was represented by cluster of visible objects or mesh-like bright echoes.With the color Doppler ultrasound scan,the contents of hernial sac of reducible hernia mostly contained red and blue stripes or echo spots of blood flow.For the irreducible hernia and incarcerated hernia,the contents of hernial sac contained less echoes of blood flow and showed bar-or star-like blood flow signals.For the strangulated hernia,the contents of hernial sac contained either no blood flow signals or very few star-like blood flow echoes.Conclusion High-frequency color Doppler ultrasound is an innovative and non-invasive method for diagnosing inguinal hernia in senile men.
