AIM:TO evaluate the clinical outcomes of double-layered self-expanding metal stents (SEMS) for treatment of malignant esophageal obstruction according to whether SEMS crosses the gastroesophageal junction (GEJ).METHODS:Forty eight patients who underwent the SEMS insertion for malignant esophageal obstruction were enrolled.Patients were classified as GEJ group (SEMS across GEHm 18 patients) and non-GEJ group (SEMS above GEJ,30 patients) according to SEMS position.Double layered (outer uncovered and inner covered stent) esophageal stents were placed.RESULTS:The SEMS insertion and the clinical improvement were achieved in all patients in both groups.Stent malfunction occurred in seven patients in the GEJ group and nine patients in the non-GEJ group.Tumor overgrowth occurred in five and eight patients,respectively,food impaction occurred in one patient in each group,and stent migration occurred in one and no patient,respectively.There were no significant differences between the two groups.Reflux esophagitis occurred more frequently in the GEJ group (eight vs five patients,P =0.036) and was controlled by proton pump inhibitor.Aspiration pneumonia occurred in zero and five patients,respectively,and tracheoesophageal fistula occurred in zero and two patients,respectively.CONCLUSION:Double-layered SEMS are a feasible and effective treatment when placed across the GEJ for malignant esophageal obstruction.Double-layered SEMS provide acceptable complications,especially migration,although reflux esophagitis is more common in the GEJ group.
