The authors treated 21 patients with inoperable upper gastrointestinal tract malignant obstruction from the esophagus to the duodenum by means of intubation with a flexible covered stent with fluoroscopic guidance. Stent placement was successful and relief of dysphagia was immediate in 18 (86%) patients, without serious complication. The average dysphagia score decreased from 2.6 (dysphagia to liquids) to 1.0 (dysphagia to normal solid food). Placement of a flexible covered stent provides easy, safe, and effective palliation of upper gastrointestinal malignant obstruction.
