Electrogastroenterogram

Electrogastroenterogram

Electrogastroenterogram is a method used to study gastrointestinal motility in the same way which it is employed in cardiac electrocardiography (cardiac ECG test). Electric signals produced by the stomach or intestine are recorded from the skin electrodes placed either on the patient’s extremities or abdomen. These signals are processed by computer using modern mathematical methods, such as band-pass filtering, wavelet analysis, and spectral analysis.

This test provides information about the peristalsis of the stomach, duodenum, jejunum, ileum and large intestine. Peristalsis provides mechanical processing of food - mixing food with digestive juice and moving it in the right direction. Thus, incoordination of the wavy muscle contractions of the digestive tract, as well as increased or decreased intensity of such contractions may lead to a variety of gastrointestinal diseases, including peptic ulcer disease. Peristalsis may also provide information about how well the blood vessels supplying stomach and intestine with blood are working, as well as about any spasms and stenoses.

Electrogastrogram. An electrogastroenterogram is a measurement of the motility of the stomach. The procedure is carried out both on an empty stomach and after eating. The procedure is completely painless and causes no aftereffects or complications. It lasts for about 2-3 hours
