Introduction: The incidence of adenocarcinomas in esophagus and the esophagogastric junction are increasing all over the world. Prognosis is poor with low survival indexes. Dysphagia is the symptom that causes most nuisances to patients, affecting their nutritional state and quality of life. The treatment of tumors of the esophagogastric junction is not very satisfactory given that diagnoses are usually made at advanced stages. Stents are used as primary palliative therapy or in case of relapse after other treatment forms such as surgery or radiochemotherapy. Materials and Methods: 13 patients were included in the study between January 2002 and December 2006, all with advanced lesions at the GE junction which was not susceptible to other types of treatment. After dilation of the malignant stenosis we proceeded to place Expandable Metal Stents in the GE junction. Results: 84,6% of the tumors were adenocarcinomas. The placement of the stents was achieved in 11 cases in the first session. Bleeding and thoracic pain were associated with the dilation. Only one patient presented stent migration to the stomach (7,6%). Conclusions: In our series there were no complications associated with the placement of the stent, and no mortality caused by the procedure. The Expandable Metal Stents are an excellent instrument in the handling of dysphagia in malignant advanced lesions of the esophagogastric junction.
