Introduction: the endoscopic insertion of self-expandable metallic stents into malignant injuries of the gastrointestinal tract has been described as palliative treatment. Objective: to report the use of such stents in patients with obstruction caused by malignant injuries, evaluated in the medical center "Valle de San Diego" and oncologic hospital "Dr. Miguel Pérez Carreño" of the Valencia, Carabobo between January 2009 and November 2011. Patients and methods: 14 stents; 6 in male subjects and 8 in female subjects, with 61,21 ± 10,43 years. The types were: esophagic Ultraflex and enteral Wallstent. Results: the injury was located in the esophagus region in 4 cases, and an equal amount in the esophagastric union and in the gastric area, 1 case in the rectocolon and another one originated by complications in neighboring organs. The histological typology (78,6%) reported as adenocarcinoma. There was a pain as a complication in one case, food obstruction and pain with migration in a one case and growth tumoral in two cases. The over life of 57,1% was between 3 and 6 months. Conclusion: the palliation was effective, by having technical and clinical success, therefore considering self-expandable metallic stents as a simple and effective solution for the palliation of malignant stenosis of the gastrointestinal tract.
