Background:
Electrogastrography (EGG) is the non-invasive measurement of gastric electrical activity. With the development of modern technology, improved recording and automated analysis, it is a reliable and accurate technique for the measurement of gastric myoelectrical activity providing information about the frequency and regularity of the gastric slow wave.
Aim:
The aim of this report is to evaluate its role in clinical practice.
Methods:
The literature is reviewed and its role investigated.
Results:
EGG has been successfully used in the investigation of gastroparesis, non-ulcer dyspepsia (NUD), gastric emptying (GE) disorders and diabetes mellitus (DM). EGG also provides an insight into the effect of medications on gastric function, e.g. edrophonium, cisapride, erythromycin and proton-pump inhibitors (PPI).
Conclusions:
EGG has a developing role in the assessment of gastric dysfunction and on the effect of medical treatment. The effect of surgery and anaesthesia on gastric myoelectric activity is less clear.
