The clinical application of three types of esophageal stent designed by ourselves

Purpose: To evaluate three types of esophageal stent designed or modified by ourselves in the treatment of esophageal stricture. Materials and methods: The three types of esophageal stent were Ni Ti spiral silk like wire stent with double trumpet ends, Ni Ti wire mesh like stent and covered stainless steel stent. 106 patients with esophageal stricture of various causes were treated. Results: Dysphagia was markedly alleviated. The covered stent was specifically effective for esophageal fistula. Follow up study from 3 to 26 months did not demonstrate adverse effects. Conclusion: These three types of esophageal stent were safe and effective in treating various esophageal strictures including fistula.
