    Abstract:
    BACKGROUND: The aim of this study was to analyze the safety and effectiveness of stenting using partially covered self-expandable stents in palliation of dysphagia in patients with unresectable esophageal cancer. METHODS: Retrospective analysis of hospital records of all patients who underwent esophageal stenting in the period 2008-2015 was performed. The study included patients with unresectable esophageal and esophagogastric cancer. RESULTS: There were 442 patients included. Mean age was 56 years (range 28-89), and 379 were males. In 40 (9.0%) patients, stenting was performed in the cervical, in 150 (39.3%)-in the middle thoracic, in 141 (31.9%)-in lower thoracic esophagus and in 111 (25.1%)-in the esophagogastric junction. Stenting resulted in significant alleviation of dysphagia grade (3.0 vs. 1.0, p = 0.00001). During the follow-up, 55 (12.4%) patients experienced recurrent dysphagia due to tumor or granulation tissue overgrowth, and in 18 (4.1%) patients, migration of the stent occurred, for which an independent risk factor was adjuvant chemo- and/or radiation therapy (p = 0.001). Minor complications included chest pain (54.5%), delayed complete stent expansion (12.0%), feeling of a foreign body (25.3%), hiccup (1.6%), gastroesophageal reflux (45.6%) and post-discharge pneumonia (2.5%). A feeling of a foreign body in the esophagus was significantly more common after stenting of the cervical esophagus (p = 0.0001), and hiccup was more common after stenting of the esophagogastric junction (p = 0.02). Major complications included bleeding (1.3%), respiratory insufficiency (0.7%), esophageal perforation (0.9%) and irregular heartburn (2.3%). Overall procedure-related mortality was 0.4%. The median survival time was 117.8 days (range 2-732). CONCLUSIONS: Stenting is an effective procedure in relieving dysphagia in patients with unresectable malignant esophageal stenosis and is associated with low rate of postoperative and long-term complications.
