The key in this case to avoid the barium is to use the right intercostal approach to the pylorus with the patient in right lateral recumbency IC11-13. This way either gastric gas or barium in this case is not in the way to imaging the pylorus that has a cloth FB embedded in it in this view. The barium just looked like viscous anechoic fluid in this view but taking the left cranial abdominal approach it created a shadow. Why this is I would have to look in kremkau or ask a nerdy radiologist because I don’t recall but this is how I get around gas and barium in GI cases.
