[Palliative treatment of esophageal neoplastic stenoses with self-expanding metallic stents].
Thirty Strecker nickel-titanium self-expanding metallic stents were implanted in 20 patients with esophageal strictures and inoperable neoplasms in the Departments of Radiology of the University School of Medicine of Ferrara, Genoa, Novara and Rome, from March 1992 to April 1993; follow-up ranged 1 to 13 months. Thanks to the stents, esophageal strictures could be dilated, significantly reducing dysphagia and allowing the patients to return on to a solid diet. Radiological and endoscopic exams proved the efficacy of the stents in all but 2 patients in whom the tumors had invaded the stent lumen and caused obstruction. In all cases the stents were highly biocompatible and well tolerated. Neither major complications, such as perforation or bleeding, were observed, nor minor ones, such as fever or migration from the site of implant, which may occur with plastic prostheses. To conclude, self-expanding metallic stents used in clinical trials for 13 months proved an effective method in the palliative treatment of malignant esophageal strictures.
