OBJECTIVES: Esophageal atresia with or without tracheo-esophageal fistula is a frequent malformation that occurs in about 1 of 3000 live births. It can be associated with other congenital malformations. The aim of this study was to measure the frequency of heterotopic pancreas (HP) in children with esophageal atresia (EA) and to evaluate possible linkage with other malformations. MATERIALS AND METHODS: All patients with EA were prospectively followed since 2005 at Hôpital Sainte-Justine and since 2006 at the Montreal Children's Hospital. We compared 91 patients who underwent gastroscopy during that period with 182 control patients who submitted to gastroscopy for other indications. The presence or the absence of HP and its localization were noted in both groups. The following data were also collected on patients with EA: sex, gestational age, EA type, and other malformations. RESULTS: Seventeen (18.7%) of the 91 patients with EA had gastric HP compared with 1 (0.5%) in the control group (OR 42, 95% confidence interval 7-249, P < 0.001). There were no differences between patients with or without HP regarding sex, prematurity, EA type, and the presence or absence of other congenital abnormalities. CONCLUSIONS: This study demonstrates, for the first time, that gastric HP is associated with EA irrespective of other malformations.
