title: Z-stent for malignant esophageal obstruction.
abstract: The Z-stent was one of the first self-expanding metal prostheses used for palliation of malignant esophageal obstruction and respiratory esophageal fistula. Its placement has proved to be effective and relatively safe. This article reviews the evolution of the Z-stent; its multiple designs, placement technique, efficacy, complications, and assets and limitations.
