Evaluation of esophageal passage in selected connective tissue diseases.

The objective of this study was to determine whether, as in with other types of connective tissue diseases, there exists esophageal passage dysfunction as it exists in systemic scleroderma. It was also interesting to establish whether there is any correlation between this kind of dysfunction and the subjective complaints connected with the esophagus as well as the occurrence of Raynaud's phenomenon. Evaluation of the esophageal passage was performed on the basis of scintigraphic examination. The delay of esophageal passage occurs, besides systemic scleroderma, in other types of connective tissue diseases. This examination is a valuable test, thanks to which changes in the esophagus can be discovered, despite the lack of subjective complaints. In addition to systemic scleroderma, there is no close correlation between dysphagia and Raynaud's phenomenon.
