New indications in the treatment of advanced esophageal cancer using self-expanding stent

In the past four years we performed palliative reconstruction in 69 patients with Tygon or Polyflex self-expanding stents. The procedure was performed in 35 patients because of mid-third oesophageal cancer, in 18 patients because of cancer of the cardia, in 7 patients because of mediastinal tumour and in 8 patients because of oesophago-respiratory fistula. The procedures improved the swallowing greatly, the oesophago-respiratory fistulae closed. During endoscopic intubation of cardia tumours the risk of perforation is high, while it is lower in case of open operative pull-through method. Insertion of Polyflex self-expanding stent under X-ray is safe. Improvement of the stents helps not only safer use, but it encourages its use in new indications, such as iatrogen benign perforation, corrosive oesophageal stricture, long preoperative period, when the swallowing for better nutrition is essential. The procedures improve the quality of life and improve survival time because of the restored swallowing, closed oesophago-respiratory fistula with the prevention of aspiration.
