[The study of the autopsies of six patients with progressive esophageal cancer to investigate complications caused by esophageal stents].
Endoscopic placement of metal stents are used widely for patients with esophageal obstruction and fistula due to progressive esophageal cancer, but cause high rate of severe complications associated with the immediate causes of death. To determine severe complications caused by stents, we studied clinical data and autopsy of six patients who had been treated with stents for inoperable progressive esophageal cancer. Occording to the clinical records only two patients had severe complications due to stents. But at autopsy, three patients had massive hemorrhage in the stent placement, one patient had mediastinitis, and one patient were in imminent danger of perforation whose stent had been incorporated into the adventitia of the wall. More severe complications were revealed than those expected clinically. Endoscopic placement of metal stents have a great deal for the improvement of quality of life. But we should carefully decide the indication because endoscopic placement of metal stents could cause severe complications associated with the immediate causes of death.
