CASTANO LLANO, Rodrigo et al. Eficacia de un nuevo stent de nitinol fabricado localmente, en el tratamiento de la obstrucción maligna esofágica. Rev Col Gastroenterol [online]. 2003, vol.18, n.4, pp.211-221. ISSN 0120-9957.

Objectives: esophageal strictures and esophagorespiratory fistulas are complications of malignant esophageal tumors and benign conditions, which are difficult to manage. The efficacy of a locally (Medellín-Colombia) produced self-expanding metal stents (SEMS) for palliation of malignant esophageal strictures and fistulas was investigated prospectively. Methods: eighty one SEMS were inserted in 77 patients, 73 patients with malignant esophageal stricture (10 with fistula) and 4 benign. Our series included 45 men and 32 women, of whom median age was 65 years. Sixty three stents were inserted for malignant strictures, ten for esophago-tracheal fistula, and four for benign conditions. Stents were inserted endoscopically only in 83% and under endoscopy and fluoroscopic control in 17%. Results: SEMS implantation was technically successful in 100%. A second stenting was needed in four patients. Median dysphagia score improved from 2,8 to 1,4 (p<0,01). The covered SEMS was succesful in completely sealing 100% of the fistulas. Complication occurred in 28,4% patients. Procedure-related mortality was 0%. Conclusions: we conclude that treatment of malignant esophageal obstructions, including esophagorespiratory fistulas, with SEMS locally produced is a good alternative palliative procedure. Furthermore SEMS implantation seems safe in the case of benign stenoses.
