Use of covered expandable metal stents in the treatment of oesophageal carcinoma and tracheo-oesophageal fistula.
Palliation for malignant dysphagia has relied on oesophageal dilatation, insertion of rigid prostheses and laser treatment. All three methods have substantial risk of perforation. Displacement of the tube is also well described. Seventeen expandable polyethylene-covered metal stents were inserted in 15 patients with oesophageal carcinoma; there were 11 men and four women, of median age 70 years. Thirteen stents were inserted for dysphagia and four for tracheo-oesophageal fistula (TOF). Stents were inserted endoscopically under fluorosopic control. Seven patients died from their disease a median of 5 (range 1-11) months after stent insertion. Median follow-up in the remainder is 6 (range 1-11) months. Median dysphagia scores before and after insertion were 3 (range 2-4) and 1 (range 1-2) respectively. Stent insertion provided cure of symptoms in patients with TOF. Median hospital stay following insertion was 2 (range 1-20) nights. There were no deaths and no perforations associated with the procedure. Two patients complained of retrosternal chest pain for 2 days after stent insertion. One patient presented with dysphagia related to later stent migration. There has been no deterioration in symptoms of dysphagia in the remainder. Expandable oesophageal stents offer a safe alternative to traditional methods of palliative treatment for oesophageal carcinoma. In the long term they may provide a cost-effective alternative to standard treatments.
