Background: self-expandable metallic stents (SEMS) are employed as the preferred non surgical palliative treatment for gastric outlet obstruction due to malignancies. Metallic stents are often employed to treat malignant anastomotic obstructions after surgicsl interventions as esophagojejunostomy, gastrojejunostomy and esophagogastrojejunostomy. Methods: this case series reports prospectively the clinical outcomes of SEMS in the palliative care of malignant anastomotic strictures caused by the recurrence gastric cancer follwing gastric surgery as oncological curative treatment, in a series of nine consecutive patients, treated between January 2009 and december 2012 in our center. Results: Nine patients (M:F=8:1) were enrolled in the study. The operation was a total gastrectomy with esophagogastrojejunostomy (n=4), subtotal gastrectomy with Bilroth-II reconstruction (n=4), subtotal gastrectomy with Billroth-II reconstruction (n=3), and subtotal gastrectomy with esophagogastrostomy (n=2). The technical success rate was 88,9%, and the clinical success rate was 88.9%. The reostruction of the stent, due to the ingrowth of the tumor, occurred in 1 patient (11,1%) within 1 month after stent placement. the migration of the stent occurred after the placement of a covered stent in 1 patient who underwent a subtotal gastrectomy (with Billroth-II reconstruction). A case o partial stent dislodgement was treated with the placement of a second stent. The median survival period was 180 days (range, 30-240 days) and the median stent patency was 45 days 8range, 30-90 days). Conclusions: Although the number of the patients treated with SEMS results, in this series, almost small to certainly judge the safety and feasibility of SEMS, we believe that the endoscopic insertion of SEMS seems to be a safe, easily feasible, and effective treatment in the palliative care of malignant anastomotic strictures caused by the recurrence of gastric cancer following gastric surgery. The technical and clinical success, and the onset of complications of this procedure are influenced by several factors, such as the type of anastomosis, the technical features of the stent, and the extent of the underlying tumor.
