Electrogastrography in patients with Roux-en-Y reconstruction after previous Billroth gastrectomy.
OBJECTIVE
The aim of this prospective study was to characterize gastric myoelectrical activity in patients with Roux-en-Y reconstruction after previous Billroth gastrectomy.


METHODS
Thirteen patients entered the study (6 men and 7 women, aged 35-57). The mean time from Roux-en-Y reconstruction to electrogastrography (EGG) recording was 5 years. Surface cutaneous EGG was recorded using a Digitrapper EGG in the morning both fasting and after a standard solid test meal. All patients assessed their dyspeptic symptoms at the time of EGG in a semi-quantitative subjective scale.


RESULTS
EGG was abnormal in all studied patients (but one postprandial recording). Dyspepsia was not meal-related and was not more severe in Helicobacter pylori positive patients. There was a significant negative correlation between time from Roux-en-Y reconstruction to EGG recording and bradygastria percent activity, both fasted and postprandial (r = -0.576; p = 0.0022). There was an inverse trend between severity of dyspepsia and normal slow-wave rhythm percent activity. Older patients tended to have more severe dyspepsia.


CONCLUSIONS
The results of this study suggest that abnormal EGG recording is associated with dyspepsia in patients after Roux-en-Y reconstruction.
