The procedure is usually done withfluoroscopic guidance. The aim of this study was toassess the use of Tracer guide wire in conjunction withSavary-Gilliard dilators in the dilation of tightesophageal strictures without fluoroscopy.METHODS: Fifty-five patients with significant dysphagiafrom strictures due to a variety of causes were dilatedendoscopically. The procedure consisted of two parts.First, a guidewire was passed using endoscopic guidance,and then, dilation was performed without fiuoroscopy.Amodified Tracer wire was employed and was particularlyeffective in negotiating very tight esophageal strictures,in which the lumen is less than 6 mm. In general, the'Rule of Three' and '2-3 sessions in 10 days, maximumdilation up to 42 French' rules were followed. 40:1dilations in a total of 55 patients(malignant strictures 30,benign 25) in 177 sessions were carried out.RESULTS: The guide wire placement and Savary-Gilliarddilation were successfully performed without fluoroscopy,and improvement of dysphagia was achieved in allpatients. Esophageal plastic stent (out diameter 40French) was placed in five patients with malignantstricture-three of them with tracheo-esophageal fistula.CONCLUSION: Dilation using Tracer guide wire withoutfluoroscopy is safe and effective in treatment of evenvery tight esophageal strictures.展开更多
