Abstract

PURPOSE
To evaluate the effectiveness, patency and safty of a self-expandable nitinol stent for palliative treatment of malignant stricture of gastroesophageal junction.
MATERIALS AND METHODS
An esophageal stent was inserted in five consecutive patients with malignant stricture of esophagogastric junction. Histologicaily, four cases were adenocarcinoma, and one was squamous cell carcinoma. The location and severity of stricture were evaluated with gastrografin just before stent insertion. In one patient with past subtotal gastrectomy, esophagography revealed fistulous tract at stricture site.
RESULTS
No technical failure or procedural complications occurred, and improvement of dysphagia was noted in all patients soon after stent insertion. On follow up esophagograms performed 3 to 7 days after stent insertion, all stents were completely expanded and unchanged in positions. In one patient with fistulous connection at stricture site, esophagogram immediately after the procedure revealed complete occlusion of the fistula. Three patients died within 4, 7 and 8 consecutive months after stent insertion. Two patients are alive maintaining adequate body weight and passing most diet.
CONCLUSIONS
Self-expandable nitinol stent with it's good longitudinal flexibility and efficient radial force was effective in the palliative treatment of dysphagia in patient with malignant stricture at esophagogastric junction.
