Abstract: ObjectiveTo investigate the efficacy and safety of the self-expandable metal stent for treatment of gastric outlet and duodenal obstruction.MethodsData of 24 patients with symptomatic gastric outlet and duodenal obstruction diagnosed from January 2005 to February 2011 were retrospectively studied.All patients were measured by gastric outlet obstruction scoring system ( GOOSS ) before and one week after the placement of self-expandable metal stent.ResultsStent placement was succeeded in all patients with a mean operation time of 25.90 ± 11.03 min.Twenty patients (83.3％) were able to intake liquid food after the procedure.The GOOSS (P50 =0) before and after stent placement were 0.14 (P50 =0) and 1.42( P50 =2),respectively,with significant difference (P ＜0.01 ).Minor digestive bleeding occurred in 3 patients,but no severe complications including perforation or aspiration were observed.ConclusionPlacement of a self-expandable metal stent in patients with gastric outlet or duodenal obstruction is safe and effective for resolving obstructive symptoms.
