vomiting. AXR AP obtained after gastric decompression via nasogastric tube (above) shows gas present through the bowel. AP image from an upper GI exam (below) shows the stomach and first and second parts of the duodenum to be extremely dilated. On a delayed image obtained 15 minutes later, a small amount of contrast was seen to have passed out of the duodenum into the small bowel.The diagnosis was duodenal stenosis.
