The consequence of this megaesophagus was a transversal widening of the mediastinum up to 6.7 x 5.2 cm in diameter accompanied by a consecutive slit-shaped cranial narrowing of the trachea (Fig. 1).
Barium swallow performed 3 months after surgical treatment. The short-term follow up demonstrates a reduced dilation of the esophagus and some retained barium inside the esophagus.

In addition, the barium remained for an extended time within the esophageal body and complete emptying of the stomach was only possible by drinking copious amounts of water (Fig. 2).
