Electrogastrographic characteristics in subjects with stomach remnant

Background and Aims:  Slow wave (SW) is an essential component in mediating stomach motility. The purpose of the present study was to investigate the SW characteristics in subjects with stomach remnant. Methods:  We consecutively enrolled 58 distal radical subtotal gastrectomy (RSG) patients (male/f...

Description
Summary:Background and Aims:  Slow wave (SW) is an essential component in mediating stomach motility. The purpose of the present study was to investigate the SW characteristics in subjects with stomach remnant. Methods:  We consecutively enrolled 58 distal radical subtotal gastrectomy (RSG) patients (male/female: 44/14, age: 33–79 years) to receive an electrogastrographic (EGG) measurement. Their Helicobacter pylori status and dyspeptic score were simultaneously assessed. In addition, EGG data of 58 age‐ and sex‐matched healthy subjects were compared. Based on power spectral analysis, the following EGG parameters were derived: dominant frequency (DF)/power (DP), percentage of normal rhythm (2–4 cpm), power ratio (PR) referring the postprandial power change, etc. Results:  Visual analysis occasionally found a short period of ∼11 cpm myoelectricity‐like rhythm. Distal RSG patients had lower fasting (1.90 ± 0.69 vs 2.97 ± 0.58 cpm, P
