Abstract Long-term manometry of the tubular esophagus was performed in 20 consecutive patients (18 females, 2 males; median age 56.5 years) with progressive systemic sclerosis (PSS) and a control group of 20 healthy subjects (18 females, 2 males; median age 56.5 years). The measurements were performed via a data logger of 1 MByte memory capacity with the help of two pressure sensors placed 8 and 18 cm above the lower esophageal sphincter. Esophageal contractions were analyzed with respect to pressure amplitudes in the esophagus distal and proximal, quotient of pressure amplitudes distal/proximal, number of contraction waves in a 24-h period, and kind of spreading (propulsive, simultaneous). In the PSS group there was a significant decrease in pressure amplitudes in the distal sensor (median 31.5 versus 39.5 mbar in controls, P 〈 0.02), in the quotient of pressure amplitudes distal/proximal (median 0.885 versus 1.25 in controls, P 〈 0.001), in the number of waves in 24 h (median 939.5 versus 1656 in controls, P 〈 0.01), and in the occurrence of propulsive waves (median 34% versus 57% in controls, P 〈 0.01). Fifteen patients (75%) had hypomotility disorders as compared to the control group, in which the lower limit of normal values was defined by the 5th percentile of descriptive analysis. These first data of long-term manometry in patients with PSS indicate that long-term manometry may be an effective method for identifying esophageal involvement in PSS.
