The authors previously showed that barium does not interfere with abdominal sonography performed after a biphasic upper gastrointestinal tract examination. This study was designed to assess the impact of a barium enema (BE) examination on the quality of abdominal sonography performed immediately after the barium enema.
Forty patients scheduled for routine barium enemas (22 air contrast and 18 solid column) were prospectively examined with abdominal sonography before and after their BEs. The resulting 80 sonograms were randomized; three radiologists blindly assessed the quality of images of each of six anatomic areas (aorta, pancreas, porta hepatis, gallbladder, and the right and left lobes of the liver).
There was no statistically significant degradation of the images for the right and left lobes of the liver and the pancreas. However, the images for the gallbladder, porta hepatis, and aorta had a statistically significant (P < .05) degradation of their ultrasound quality following barium enema.
Unlike upper gastrointestinal tract examination, BE examination does interfere with the quality of a subsequent abdominal ultrasonography. Thus, when both studies are required, sonography should be performed first.
作者之前曾表明，在双相上消化道检查后进行腹部超声检查时，钡剂不会产生干扰。本研究旨在评估钡剂灌肠（BE）检查对钡剂灌肠后立即进行的腹部超声检查质量的影响。
对40例计划进行常规钡剂灌肠的患者（22例空气对比灌肠和18例固体柱状灌肠）在钡剂灌肠前后进行腹部超声前瞻性检查。将得到的80幅超声图像随机分组；三位放射科医生对六个解剖区域（主动脉、胰腺、肝门、胆囊以及肝左右叶）的每一幅图像质量进行盲法评估。
肝脏左右叶和胰腺的图像质量没有统计学上的显著下降。然而，钡剂灌肠后胆囊、肝门和主动脉的超声图像质量有统计学意义的显著下降（P < .05）。
与上消化道检查不同，钡剂灌肠检查确实会干扰随后腹部超声检查的质量。因此，当两项检查都需要时，应先进行超声检查。
