Self-expandable metallic stents are being used increasingly to maintain luminal patency in patients with unresectable gastric outlet obstruction. Stent technology has facilitated placement of the stent in the pyloric or duodenal obstruction. An example of advances in technology is the innovative through-the-scope (TTS) stent, which is not yet commercially available in Japan. Enteral stents provide a high success rate, quick relief from symptoms, and an improvement in the performance score, although some complications remain. This article reviews the current status of stent placement for gastric outlet obstructions. The self-expandable metallic stent seems to provide a potentially attractive alternative to surgical bypass, since most of these patients are terminally ill with a limited life expectancy. Available data is currently insufficient to clarify the use of stents for gastric outlet obstructions, therefore a prospective randomized comparison is required to compare this procedure with surgical alternatives.
