Patients with esophageal atresia and proximal pouch fistula have plain films that simulate esophageal atresia without fistula. Clinical suspicions of the existence of the proximal pouch fistula may occur when marked aspiration of barium occurs following outlining of the proximal pouch, or by choking spells during irrigation of the proximal pouch. Outlining of the fistula from the pouch requires some form of continuous imaging, either with T.V. tape, cine or 70 mm. spot films. Of interest is the fairly long distal esophageal segment found in the three cases reported, as opposed to the usual short segment of the distal esophagus seen in infants with esophageal atresia without fistula.
患有食管闭锁和近端盲袋瘘的患者的平片表现类似于无瘘的食管闭锁。当在勾勒出近端盲袋后出现大量钡剂吸入，或者在冲洗近端盲袋时出现呛咳发作时，临床上可能会怀疑存在近端盲袋瘘。要从盲袋勾勒出瘘管需要某种形式的连续成像，无论是通过电视录像带、电影还是70毫米点片。有趣的是，在所报道的三例病例中发现远端食管段相当长，这与无瘘的食管闭锁婴儿中常见的远端食管短段形成对比。
