title: Solid phase radionuclide esophageal transit in mixed connective tissue disease.
abstract: Esophageal motility was studied in 24 patients with mixed connective tissue disease (MCTD) and 20 control subjects by the solid phase radionuclide esophageal transit study. A computer routine modified from Klein and Russel was used. Total mean transit time, regional mean transit time, residual fraction after first swallow, and retrograde index increased significantly in MCTD patients compared with normal control subjects. An abnormal total mean transit time occurred in 84% (20 of 24) of the patients with MCTD. Our results confirmed that delayed esophageal transit is common in patients with MCTD.
