Management of Malignant Strictures of the Cervical Esophagus with a Newly-Designed Self-Expanding Metal Stent

Recently, the use of self-expanding metal stents has become a well-established method of palliative treatment for stenotic malignant diseases in the middle and distal esophagus. However, published results on the use of self-expanding metal stents in cervical esophageal cancer are somewhat limited by a paucity of clinical details and experience. A new self-expanding esophageal metal stent with a short upper flange 0.7 cm in length was studied prospectively in order to assess its efficacy for palliative treatment. This report presents experience in three patients in whom this new stent was used in the treatment of cervical esophageal cancers. Stent placement was successful in all three patients, with no serious complications such as esophageal perforation, hemorrhage, or foreign-body sensation. All of the patients experienced rapid improvement in dysphagia and clinical symptoms. The newly designed self-expanding stent can be of value in the treatment of stenotic cervical esophageal cancer.
