식도-위 연결부의 악성협착에 의한 연하장애 : 자기 팽창성 니티놀 스텐트로의 치료 = Dysphagic with Malignant Stricture of Esophagogastric Junction : Treatment with Self-expandable Nitinol Stent

다국어 초록 (Multilingual Abstract)

Purpose: To evaluate the effectiveness, patency and safty of a self-expandable nitinol stent for palliativetreatment of malignant stricture of gastroesophageal junction Materials and Methods: An esophageal stent wasinserted in five consecutive patients with malignant stricture of esophagogastric junction. Histologically, fourcases were adenocarcinoma, and one was squamous cell carcinoma. The location and severity of stricture wereevaluated 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 proceduralcomplications occurred, and improvement of dysphagia was noted in all patients soon after stent insertion. Onfollow up esophagograms performed 3 to 7 days after stent insertion, all stents were completely expanded andunchanged in positions. In one patient with fistulous connection at stricture site, esophagogram immediately afterthe procedure revealed complete occlusion of the fistula. Three patients died within 4,7 and 8 consecutive monthsafter 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 inthe palliative treatment of dysphagia in patient with malignant stricture at esophagogastric junction.
