BACKGROUND: We aimed to evaluate the short- and long-term outcomes of treatment by insertion of a covered expandable modified Gianturco-Z endoprosthesis (Song stent) in patients with esophagogastric malignancies. METHODS: Consecutive patients with esophagogastric malignancies in whom a Song stent was inserted were included. Data were retrieved retrospectively. Dysphagia before and after stent placement was scored on a 5-point scale. Early (less than 30 days) and late complications (more than 30 days) were scored. RESULTS: Analysis included 164 stents in 153 patients. Indications for stent placement were dysphagia and/or fistulas/perforations. The dysphagia score improved from a mean of 3.7 to 2.2 after stent placement (p < 0.0001). Fistulas/perforations sealed in 87% of cases. Early complications after stent placement occurred in 29.9% of cases. These included stent migration (4.3%), stent obstruction (6. 1%), aspiration pneumonia (4.9%), bleeding (4.3%), perforation (1. 8%), and pain (15.9%). Late complications occurred in 27.8% of cases. These included stent migration (2.6%), stent obstruction (9.6%), aspiration pneumonia (2.6%), bleeding (7.0%), perforation (0.9%), and pain (12.2%). The 30-day mortality was 26%. Death related to stent placement occurred in 3.3%. CONCLUSION: Insertion of a Song expandable endoprosthesis in patients with esophagogastric malignancies significantly improves dysphagia, is successful in sealing fistulas/perforations, and is associated with acceptable morbidity and mortality rates.
