[Esophageal motor changes in patients with Raynaud's phenomenon and suspected scleroderma. Electromanometric and serologic evaluations].

Esophageal motor dysfunction in patients with collagen disease, although rather frequent, presents difficult etiopathogenetic arrangement. By means of esophageal manometric evaluation and immunopathologic study the Authors observed 44 patients with Raynaud's phenomenon idiopathic or joined with Scleroderma. From collected data the utility of esophageal manometry in early diagnosis is pointed out.
