title: [Computerized analysis of esophageal manometry].
abstract: Computerized analysis of esophageal manometry should consider the following objectives: a) objectivation of data acquisition; b) precision in calculating the various parameters; c) speed of analysis; d) an easy-to-read and promptly understandable graphic display of the manometric data; e) computation of new parameters capable of defining normal and pathologic function. It is with these objectives in mind that we launched our research project. Five normal subjects and 10 patients, of whom 5 presented esophageal achalasia and 5 gastroesophageal reflux disease, underwent computerized esophageal manometry and were evaluated on the basis of both traditional and innovative parameters, of our own inception. Among the various indexes tested, the "Esophageal transport" parameter, calculated as the ratio of momentum (dp*dT) over speed of propagation of the esophageal contractions, gave rise to particular interest. In our opinion, this parameter can be used as an index of the dynamic function of the organ.
