【Abstract】 Objective:The efficacy of using water balloon dilator to treat esophageal stenosis was evaluated.Methods:The electronic gastroscopy and MAXFORCE TTS water balloon catheter dilator were adopted to dilate esophageal stenosis in 86 patients.Results:The calibres of the stenotic orifice is 0.6～1.0 cm in 24 cases,0.3～0.5 cm in 55 cases and less than 0.3 cm in 7 cases.After endoscopy therapy the calibres was dilated to 0.6～1.1 cm in 34 cases and more than 1.2 cm in 49 cases with significant effects. The rate of effect is 96.4%. Conclusion:The endoscopic water balloon dilation is easy to master with high efficiency and safety.更多还原
