METHODS: SEMS were implanted in the presence of fluoroscopic guidance in patients suffering from advanced and non-resectable esophageal, cardiac and invasive lung cancer between 2002 and 2009. All procedures were performed under conscious sedation. All patients had esophagus obstruction and/or fistula. In all patients who required reintervention, recurrence of dysphagia, hemorrhage, and fistula formation were indications for further endoscopy. Patients' files were scanned retrospectively and the obtained data were analyzed using SPSS 13.0 for Windows. The χ 2 test was used for categorical data and was analysis of variance for noncategorical data. Patients' long-term survival was assessed using the Kaplan-Meier method. RESULTS: Stents were successfully implanted in 90 patients using fluoroscopic guidance. Reasons for stent implantation in these patients were esophageal stricture (77/90, 85.5%), external pressure (8/90, 8.8%) and tracheo-esophageal fistula (5/90, 5.5%). Dysphagia scores (mean ± SD) were 3.37 ± 0.52 before and 0.90 ± 0.43 after stent implantation (P = 0.002). Intermittent, nonmassive hemorrhage due to the erosion caused by the distal end of the stent in the stomach occurred in only one patient who received implementation at cardioesophageal junction. Mean survival following stenting was 134.14 d (95% confidence interval: 94.06-174.21).CONCLUSION: SEMS placement is safe and effective in the palliation of dysphagia in selected patients with malignant esophageal strictures. 关 键 词：ESOPHAGUS cancer Stenosis STENTS Complication DYSPHAGIA
