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)

CT

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 (

P

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.
