ABSTRACT
Tumors in the cervical portion of the esophagus have traditionally been more difficult to manage. The implantation in the cervical esophagus is a technically demanding procedure. The implantation of modified self-expandable metal stents (SEMSs) was very effective perorally under endoscopic and fluoroscopic guidance. Experience with SEMS has revealed an increased risk of migration when either covered stents are used or a stent is implanted across the gastroesophageal junction. The modified, covered, esophageal stents appear to prevent stent migration and improve dysphagia in patients with malignant tumor stenosis at the esophagogastric junction. Besides heartburn, regurgitation is sometimes very distressing to patients and may lead to fatal aspiration due to reflux after stenting in esophagogastric junction. These symptoms can be reduced by the use of valved stent. The long S-shape valve is very effective in preventing acid reflux and valve inversion.
