Sonographic upper gastrointestinal series in the vomiting infant: how we do it.

ABSTRACT

Sonography (ultrasound) is used routinely to assess an infant with nonbilious projectile emesis. Fluoroscopic upper gastrointestinal (UGI) series has been the standard method to evaluate infants with bilious emesis. We use sonographic UGI routinely to assess infants with nonbilious emesis as well as infants with bilious emesis. This essay illustrates our technique, the results obtained using this technique for normal anatomy, and the commonly encountered pathology.
