Objective To investigate the curative effect of dumbbell-shaped balloon on esophageal stenosis in 115 cases of esophageal stenosis with E V I S200 series S Y dumbbell-shaped balloon catheter dilator. Results This group before expansion diameter of 0.3 ~ 0.5cm, after the first expansion of the obvious effect of 55 patients, expanded to more than 1.2cm in diameter; effective in 56 cases, the expanded diameter of 0.6 ~ 1.1cm, 4 cases due to anastomotic stenosis with severe angular deformity, expanded 3 times after the caliber expanded from 0.4cm to 1.2cm. Conclusion This method is simple, easy, safe, reliable and can quickly open the feeding channel, to solve the patient suffering from eating difficulties, to avoid thoracotomy, a significant effect.
