[X-ray diagnosis of rare esophageal diseases in children].

Clinical and X-ray studies of 300 children aged hours to 14 years who had abnormalities of the esophagus have revealed its atresia with or without tracheoesophageal fistulas in 77 subjects, that with congenital narrowings in 21. It was proved that some varieties of atresias might be roentgenologically detected and comprehensive studies should be carried out to determine fistulas in the completely patent esophagus. Despite the age, all children with esophageal atresia with a lower fistula were found to develop catarrhal and erosive esophagitis and "corrosive" pneumonia. Hamartia and recanalization impairments of the primary intestinal tube result in congenital esophageal narrowings leading not only to obstruction, but to aspiration obstructive changes in the lung.
