Abstract:
We present three patients with retroperitoneal tumor involving the duodenum in whom upper gastrointestinal (GI) studies revealed delayed gastric emptying and massive gastric dilatation out of proportion to the degree of duodenal dilatation. While the radiographic findings mimicked acute gastric outlet obstruction, delayed films demonstrated narrowing and encasement of the duodenum at the site of obstruction in all three patients. Thus, the duodenum should be carefully evaluated radiographically in patients with acute gastric dilatation, particularly if there is a known history of malignancy.
