CASTANO LLANO, Rodrigo et al. Self expandible metalic stents in malignant esophageal and gastroduodenal obstruction. rev. colomb. cir. [online]. 2005, vol.20, n.1, pp.33-48. ISSN 2011-7582.

Management of malignant obstruction of the gastrointestinal tract constitutes a major challenge. Most patients are in a state of profound depletion due to the underlying malignancy and are not ideal candidates for major operative procedures. In recent years, self-expandible metal stents have shown to be an effective and safe, less invasive alternative in the treatment of malignant esophageal and gastroduodenal obstruction. We hereby report a prospective study of 99 esophageal and 60 gastroduodenal stents placed over the past four years, together with a literature review. Technical and clinical success rates were 96% and 85%, respectively. The majority of patients tolerated oral feeding within the first 36 hours following placement of the stent. There were no major complications, such as bleeding or perforation, and there were no deaths. Thirteen patients developed signs of obstruction of the stent, and they were successfully managed by endoscopy. Our data confirm the efficacy of the stent in the palliation of malignant esophageal and gastroduodenal obstruction and the method is associated with low complications rates.
