探讨研究高频彩色多普勒超声在白线疝诊断中的应用价值。

回顾性分析2007年1月至2014年12月解放军总医院24例经外科手术证实为白线疝患者的临床资料和声像图表现。

术前高频彩色多普勒超声检查发现，疝的发生部位均位于剑突与脐孔之间的腹壁中线处，腹白线缺损处（疝环）直径0.4～2.8 cm，疝囊大小（1.1 cm×0.3 cm×1.0 cm）～（8.0 cm×3.1 cm×7.2 cm），疝囊形态多不规则，疝囊内回声因内容物不同而表现不同，主要分为3类，第1类内容物为腹膜外脂肪，声像图表现为较均匀或不均匀的低回声，第2类内容物主要为网膜，声像图表现为中等稍低回声，第3类内容物主要为肠管，声像图表现为疝囊内可见肠管样回声，动态观察并可见其蠕动。

高频彩色多普勒超声可以清楚地显示腹白线的连续性情况、测量缺损的直径、疝囊的大小、判断疝的内容物以及有无嵌顿疝等情况，并具备无损伤、廉价、可重复性好、可动态观察等优势，对于白线疝的诊断有很好的敏感性和特异性，因此对白线疝的临床诊断具有非常重要的价值。

To explore the application value of high frequency color Doppler ultrasound in the diagnosis of linea alba hernia.

From January 2007 to December 2014, The clinical data and sonographic findings of 24 patients in Chinese PLA general hospital with linea alba hernia confirmed by surgery were retrospectively analyzed.

Preoperative high-frequency color Doppler ultrasonography revealed that the site of hernia was located in the midline of the abdominal wall between the xiphoid and the umbilicus. The diameter of the abdominal white line (hernia ring) was about 0.4 to 2.8 cm in diameter. The size was about (1.1 cm×0.3 cm×1.0 cm) to (8.0 cm×3.1 cm×7.2 cm). The shape of the hernia sac was irregular, and the echo in the sac was different because of different contents. It was mainly divided into three categories. The first type of content was extraperitoneal fat, the sonogram showed a relatively uniform or uneven hypoechoic. The second type of content was mainly the omentum, the sonogram showed a moderately low echo. The third type of content was mainly the intestine, and the sonogram was the sac. Intestinal echoes could be seen inside, and their peristalsis could be observed dynamically.

High-frequency color Doppler ultrasound can clearly show the continuity of the abdominal white line, measure the width of the defect, the size of the hernia sac, determine the contents of the hernia, and the presence or absence of incarceration, and have non-invasive, non-invasive, inexpensive. It has good reproducibility and dynamic observation. It owns good sensitivity and specificity for the diagnosis of linea alba hernia, so it is very important for the clinical diagnosis of leucorrhea.
