Recently, an indication of gastrointestinal stenting is not only esophageal stenosis but it extends from the esophagus to the gastric outlet and duodenum. However, there are some problems such as shortness of the device for esophageal stenting, angulations of stenotic sites, and so on, when we perform the stenting for stenoses of the gastric outlet and duodenum. Until now, some refinements of stent insertion technique have been attempted to solve these problems. In this paper, we report three cases in which self‐expanding metallic stents were placed for stenoses of the gastric outlet and duodenum with refinements of stent insertion technique. Our attempts in these patients were an extension of stenting device to insert stents easily, and placement of covered metallic stent inside non‐covered metallic stent or a fixation of covered metallic stent to the gastrointestinal wall by means of endoclips to avoid dislocation of stents. Stents were inserted successfully in all patients, and the nutrition of these patients was improved after the placement of stents. Further refinements of stents and stent insertion technique are expected to achieve easy manipulation.
