Contraction pattern variations in oesophagography.
In recent literature a pattern of transient transverse folds seen in oesophagography has been described as a new variant. It is suggested, however, that the pattern is part of a spectrum of oesophageal contractions that occurs with or without specific lesions, and that it is created by contraction of the transverse oblique muscles of the oesophagus.
