Abstract: Objective: To evaluate the remittent function and safety of ballon dilation in treatment of patients with cardial benign stenosis of esophagus accompanied with dysphagia and to observe the near-term effect.Methods: The ballon was put into the narrow part of the esophagus of 17 patients through their mouths using a saccular catheter.Twenty percent of meglumine adipiodone was injected into the ballon to expand the ballon to a diameter of 2.5-3.5 cm.Results: The effective rate was 94.12%(16/17) one week after the ballon dilation and 82.35%(14/17) three months later.Esophageal perforation occurred in one case(1/7).Conclusions: Ballon dilation is safe and effective for treatment of cardial benign stenosis of esophagus.
