Abstract
The evaluation of morphology and functional regulation in the closing mechanism of the terminal esophagus is not yet convincingly stated. Manometry by continuously perfused and withdrawn catheters, as applied in the last years, permits only to record the elevated perfusion resistance in narrow segments. This is elucidated considering the physical principles of the measuring procedure. The closing pressure and its variations can only be determined by measuring the perfusing rate under constant pressure levels. The single conditions and the clinical value are discussed in detail.
