OBJECTIVE: To improve the technique of esophageal self-expanding metal stent and observe and evaluate the effect of esophageal self-expanding metal stent in the treatment of benign and malignant esophageal stenosis. Methods: Twenty patients with esophageal benign and malignant strictures were treated with esophageal self-expandable metal stent under X-ray monitoring. Results: All the stents were successfully implanted. A total of 22 stents were placed, including 2 Wallstent stents and 1 Z stent. The postoperative 3D radiographs evaluated the stent expansion, 16 cases were swollen, accounting for 80%, 4 cases were medium swollen, accounting for 20%, and the degree of dysphagia was reduced to 1.3 on average. Conclusion: Esophageal self-expanding metal stent is a safe, effective and simple method for the treatment of benign and malignant esophageal stenosis with less complications, high success rate and obvious curative effect.
