Duodenal stenting for malignant disease related to gastric outlet obstruction(GOO) has been covered by health insurance in Japan since April 2010. We inserted WallFlexTM duodenal stents(WDS) in 4 patients with GOO caused by unresectable gastric cancer. WDS insertion was successful in all 4 cases. Duodenal perforation occurred in 1 case. One case each of stent obstruction and stent migration occurred. All patients could eat a soft-food diet for 3-6 months (median, 5.3 months). Survival time ranged between 5 and 14 months (median, 6 months). Three patients underwent S-1 combination chemotherapy. Duodenal stenting is expected to be effective for advanced gastric cancer related to GOO.
