title: [Balloon dilation with gastroscope for esophageal stricture in children].
abstract: OBJECTIVE
  To evaluate the efficacy and safety of balloon dilation (BD) with gastroscope in treatment of esophageal stricture in children.
  
  
  METHODS
  BD was performed in 12 children aged 5 - 59 months, average age 26 months, course of disease was 2 - 26 months, with esophageal stricture, 7 cases with anastomotic strictures secondary to surgical repair of esophageal atresia, 3 with congenital esophageal stenosis, 2 with corrosive esophageal strictures. All procedures were performed under tracheal intubation and intravenous anesthesia using the 3rd grade controlled radial expansion (CRE) esophagus-balloon with gastroscope. Firstly the balloon was inserted into the esophagus through mouth, then put in the gastroscope. Under the direct guidance of gastroscope the balloon was positioned across the stricture, then the balloon was filled with saline to get needed pressure and maintained for 3 minutes. The procedure was repeated 3 times at an interval of 3 minutes. The abdominal pain, melena and vomiting were observed, as well as the diet taken thereafter, the size of the stricture and the nutrition status were observed for 3 to 12 months after the dilation.
  
  
  RESULTS
  Twenty-two dilations were performed in 12 cases, 19 succeeded, 3 cases developed complication during the dilation, the total success rate was 86%. The procedure failed in 3 cases and succeeded in 9 cases, the effective rate was 75%. Follow-up and repeated gastroscopy were performed within 3 to 12 months after the dilation, the diameter of the stricture was 9-13 mm, compared with 2-8 mm before the dilation. Eight of the children could take solid food and nutritional status was improved.
  
  
  CONCLUSIONS
  BD with the 3rd grade CRE esophagus-balloon under gastroscopy is a simple and effective method to treat esophagus stricture in children, especially for anastomotic strictures secondary to surgical repair of esophageal atresia.
