Reexamination of the deleterious effects of gastrointestinal contrast material on abdominal echography

DA Sarti and A Lazere

Diagnostic ultrasound examinations of the abdomen are usually performed prior to barium studies due to deleterious effects of gastrointestinal contrast material on abdominal echography, as demonstrated by Leopold. The authors repeat the classic in vitro study, extending the time of the experiment. As barium settles, ultrasound is able to penetrate barium filled masses. A clinical case of barium filled stomach secondary to gastric outlet obstruction is presented in support of the in vitro findings. Patients with persistent collections of barium of one or two days' duration may undergo abdominal ultrasonic examinations.
