Esophageal stents: findings on esophagography in 46 patients.
OBJECTIVE
The purpose of this report is to assess the findings on esophagography in patients with esophageal stents for palliation of malignant tumors involving the esophagus.


CONCLUSIONS
Radiologists should be familiar with findings of little importance (stent narrowing, flow of contrast medium around stent, stent kinks, and apparent esophageal narrowing below stent because of incompletely distended hiatal hernias) versus more important findings (polypoid defects above or below stent, narrowing within or below stent, delayed stent emptying, esophageal-airway fistulas, stent migration, and abutting of distal stent against greater curvature of stomach) on esophagography after stent placement to guide endoscopists regarding the need for stent revision.
