Malignant esophageal obstruction and esophagorespiratory fistula: palliation with a polyethylene-covered Z-stent.

Abstract

Polyethylene-covered stents are a relatively safe and effective means of long-term palliation in patients with severe malignant esophageal obstruction and esophagorespiratory fistula. These stents are easily deployed, and the rate of stent migration is relatively low.
