【Abstract】 Objective The efficacy of using balloon dilator to treat esophageal stenosis was evaluated.Methods The EVIS (endoscopic video information system) 200 series SY dumbbell balloon was adopted to dilate esophageal stenosis in 115 patients. Results The general calibres of the stenotic orifice remained as small as 0.3～0.5cm before dilatation.That were dilated with first attempt to 1.2cm in 55 individuals with significant effects.Following second session that opened to 0.6～1.1cm in diameter in 56 cases with good results.Three sessions of dilatation were necessary for 4 serious cases to obtain remarkable effect,the orifices being dilated from 0.4cm to 1.2cm. Conclusion The procedure of this dumbbell balloon dilator is easy to master with high efficiency and safety.更多还原
