[New method of non invasive examination of the gastroenteric tract]

A new non-invasive method for studying the gastrointestinal tract. The Authors, after a critical evaluation of the methods used to study gastrointestinal motility, evaluate the diagnostic power of electrical activity recorded from the abdominal surface. Physiological principles of gastrointestinal electrical activity, recording methods and statistical analyses of the signal are discussed. A review of the literature is included. It is suggested that this method represents a more accurate, non-invasive diagnostic tool for gastrointestinal disorders.
