An upper gastrointestinal series
showed that con- trast filled the small intestine and simultaneously overflowed into the right, dilated renal pelvis at the second part of the duodenum (Fig.2).
In patients who are at high risk for SMA syndrome, an upper gastrointestinal series
or computed tomography may be warranted to rule out the condition.
Upper gastrointestinal series
with barium contrast is a useful tool to localize the lesion with relations hips to the esophagus and stomach.
Effervescent agents were used to distend the stomach according to procedures such as those used in the acquisition of an upper gastrointestinal series
of images (barium swallow) and 3D stomach CT.
If the obstruction did not resolve by 10-14 days, they suggested further investigation with upper gastrointestinal series
and consideration of operative management.
