title: [Esophageal atresia type I. Is impossible possible?].
abstract: BACKGROUND
  Treatment of esophageal atresia with "long gap" remains difficult and controversial. According to the idea that esophageal anastomosis is imposible in most cases, several esophageal substitution methods have been proposed, as esophagocoloplasty, gastric transposition or reversed gastric tube. Nevertheless reconstruction of native esophagus is accepted as the best option if posible. "Long gap" definition is imprecise, expressed by variability in percent of these cases in total esophageal atresias reported in different series in literature. We report our experience in seven cases type I esophageal atresia with long gap and the different therapeutic options used, with attention to delayed or early esophageal anastomosis feasibility and outcome.
  
  
  METHODS
  We have treated 121 patients with esophageal atresia from whom we analized 7 cases with pure esophageal atresia with "long gap" (5.8%). Six patients underwent gastrostomy and two gastrostomy and esophagostomy. Five patient underwent primary repair with esophageal anastomosis, delayed between 14 days and 4 months in 4 cases. One patient underwent esophageal anastomosis in the first day without gastrostomy. Retroesternal esophagocoloplasty was performed in 2 patients about their first year of life. Esophagogram was done in first month after surgery and pH monitoring of gastroesophageal reflux. Follow-up ranged from 6 months to 28 years.
  
  
  RESULTS
  Esophageal anastomosis was feasible in all 5 patients in whom it was tried. Stricture occurred in two patients, one patient underwent anastomotic resection and new esophageal anastomosis. Esophageal reflux was present in two patients, one of them required funduplication. One patient was dead by complications of cardiac malformation. Remaining patients have normal swallowing and are in normal growth curves. Patients with esophagocoloplasty had not relevant early or late complications.
  
  
  CONCLUSIONS
  In most pure esophageal atresia, delayed or even early esophageal anastomosis is feasible, making use of surgical and anesthesic sources that favour it. Esophageal substitution techniques can be reserved if this approach fails.
