The use of a constantly perfused side hole sensor (CPSH) for continuous measurement of maximal lower esophageal sphincter pressure (LESP) is associated with important but variable undermeasurement as a result of side hole displacement. A 5 cm long pressure sensor has been developed which measures maximal LESP continuously in the face of movement of the sphincter within the sensor length. This sensor, the perfused sleeve, is described, and validated by comparison with CPSH in man, the dog, and a model esophageal sphincter. The sleeve detects maximal LESP accurately, regardless of sphincter length, over the pressure range encountered in the lower esophageal sphincter. Continuous recording of LESP with the sleeve is unaffected by displacement that causes serious undermeasurement with CPSH.
