Oesophageal manometry. Experience with the Arndorfer hydraulic-capillary infusion system

The value of a new system for the performance of oesophageal pressure and motility studies incorporating a hydraulic-capillary infusion pump has been assessed in 100 patients presenting to a regional cardiothoracic surgical unit with oesophageal dysfunction. This system has many advantages over conventional methods for the routine clinical assessment of oesophageal function.
