摘要

目的：

利用西甲硅油去除胃肠黏膜表面的气泡及黏液的作用，减少气体反射对超声的干扰，改善超声穿透性，提高腹部超声的诊断质量。

方法：

选择因胃肠腔内气体多、反射强、严重干扰超声穿透性、目标显示不清、声像图质量差而不能明确诊断的患者，予口服西甲硅油-纯净水混合液（研究组95例）或纯净水（对照组96例）后复查，将声像图结果进行前后对比，分析声像图的清晰度及病灶检出率，将阳性患者的超声结果与经内镜逆行性胰胆管造影（endoscopic retrograde cholangiopancreatography，ERCP）、磁共振胰胆管造影（magnetic resonance cholangiopancreatography，MRCP）、CT、MRI或手术病理结果等进行比较分析，评估西甲硅油的作用。

结果：

研究组中，63.16% （60/95）患者胃肠道气体基本消除，超声穿透性明显提高，能清晰显示胃十二指肠周围结构、有无病灶及病灶大小和位置等；20.00%（19/95）患者气体明显减少，穿透性提高，声像图清晰；14.74%（14/95）患者气体部分减少，穿透性有所改善，声像图清晰度提高；2.11%（2/95）患者气体消除不明显，穿透性无改善，声像图不满意。对照组中，15.63%（15/96）患者气体明显减少，穿透性提高，声像图清晰；37.50%（36/96）患者气体部分消除，穿透性有所改善，声像图清晰度提高；46.88%（45/96）患者气体消除不明显，穿透性无改善，声像图不满意。研究组与对照组在消除胃肠腔内气体、提高超声穿透性方面差异有显著统计学意义（

0.01）。

结论：

超声穿透性改善与胃肠腔内气体消除程度密切相关，口服西甲硅油能有效消除胃肠黏膜表面的气泡及黏液，增加超声穿透性，明显改善胃肠周围结构和病灶显示，从而提高超声检出率及准确率，有较高的临床实用价值。

Abstract

Objective:

To improve the penetration of ultrasound and quality of abdominal ultrasonic diagnosis by using simethicone

which can remove the bubble and mucus on the surface of gastrointestinal mucosa

and help to reduce the reflection of ultrasound caused by gas.

Methods:

The participants whose abdominal ultrasonic diagno

ses were severely interfered by the gas in the gastrointestinal tract were chosen. The 95 participants (experimental group) took the mixture of water and simethicone and 96 participants (control group) only took water. Then

all participants underwent abdominal ultrasound again. To evaluate the effect of simethicone

the quality of ultrasonograms and the detection rates of lesions between the two groups were compared. The results of ultrasound in positive participants were compared with those of endoscopic retrograde cholangiopancreatography (ERCP)

magnetic resonance cholangiopancreatography (MRCP)

MRI and surgical pathology.

Results:

In the experimental group

63.16% (60/95) of the participants hardly had gas in the gastrointestinal tract

the penetration of ultrasound and quality of ultrasonogram were greatly improved

the surrounding gastroduodenal structures were clearly shown

and the existence and location of lesions could be accurately detected; 20.00% (19/95) of the participants had obvious removal of gas in the gastrointestinal tract

the penetration of ultrasound and quality of ultrasonograms were improved; 14.74% (14/95) of the participants had partial removal of gas in the gastrointestinal tract

the penetration of ultrasound and quality of ultrasonograms were improved in a certain extent; 2.11% (2/95) of the participants had no obvious removal of gas in the gastrointestinal tract

and there was no improvement in the penetration of ultrasound and quality of ultrasonograms. In the control group

15.63% (15/96) of the participants had obvious removal of gas in the gastrointestinal tract

the penetration of ultrasound and quality of ultrasonograms were obviously improved; 37.50% (36/96) of the participants had partial removal of gas in the gastrointestinal tract

the penetration of ultrasound and quality of ultrasonograms were improved in a certain extent; 46.88% (45/96) of the participants had no obvious removal of gas in the gastrointestinal tract

and there was no improvement in

the penetration of ultrasound and quality of ultrasonograms. There were significant differences in the removal of gas and penetration of ultrasound between the two groups (

0.01).

Conclusion:

The penetration of ultrasound is closely related to the amount of gas in the gastrointestinal tract. Taking simethicone orally could efficiently eliminate the bubbles and mucus on the surface of gastrointestinal mucosa

improve the penetration of ultrasound and quality of ultrasonograms

and increase the detection rate of the existence and location of lesions. Therefore this method has high clinical practical value.
