Upper gastrointestinal contrast study

This upper gastrointestinal contrast study (UGI) in an oblique projection demonstrates filling of the stomach and proximal duodenum with contrast (left side of photograph). Distal to this (dark arrowhead), there is compression of the third portion of the duodenum with only a scant amount of contrast in this region. This patient had repair of his scoliosis as evidenced by the hardware (right side of photograph).
