The researchers investigated a new expandable plastic stent in the palliation of malignant esophageal obstruction.
They reported their findings in the May issue of the American Journal of Gastroenterology.
Eight patients with malignant esophageal obstruction and dysphagia were studied.
An expandable covered plastic stent, made of polyester netting and covered with a silicone membrane, was inserted and released into the stenosis. Relief of dysphagia and functional status were measured.
The stent was successfully inserted in all eight patients.
The median dysphagia score was found to drop from 3 (able to eat liquids only) to 1 (some dysphagia with solid food).
Seven of the eight patients had an improvement of at least two grades of dysphagia.

The investigators found the mean survival to be 87 days (range 17-226).
Stent migration occurred in one patient after 50 days; stent occlusion due to tumor in-growth was not seen.
Researcher N Bethge concluded on behalf of fellow authors, "A low-cost (approximately $400) expandable plastic stent has been developed that is safe and effective in the palliation of malignant esophageal obstruction.
"Large randomized trials comparing this stent to expandable metal stents are warranted."
