[Functional study of the esophagus in progressive systemic sclerosis: utility of the manometry].

The authors report their experience about the esophageal manometry in patients with Progressive Systemic Sclerosis (PSS). From January 1987 to December 1991, 32 patients (27 females and 5 males, in the ratio of 5.4 to 1; mean age of 56.6 years, range 18-84) were send to our Department with the diagnosis of PSS. The patients were divided in two group according to the presence or absence of esophageal symptoms. The first group (A) of 12 patients without symptoms, was examined only with manometry, while the second (B) was studied with the 24-hour pH-monitoring and esophagoscopy. In the group A the manometry noticed in 9 cases (75%) various degrees of esophageal motility disorders; in B the 90% of cases had a more or less severe disorder of the peristalsis. Moreover the grade of esophagitis and the importance of the gastroesophageal reflux were proportioned to the motility disorders. The conclusion is that also the subjects with PSS, but without esophageal symptoms, have in a high percentage motility disorders of the viscera. The alterations of the peristalsis increases in the group of symptomatic patients associated with esophagitis and severe reflux. On account of the fact that the esophageal lesions involve not only the LES but also the esophageal body, it is clear that the anti-reflux surgical procedures fail and an early medical therapy is the more adequate treatment.
