Our previous work demonstrated that electric vagal stimulation in conjunction with Congo red as a dye-indicator is the faster and more reliable method for delineating the corpus-antral boundary in rats. Based on this finding, our study was extended to a larger animal model, the dog; this study proved the electrical vagal stimulation along with Congo red is a reliable method for adequate demonstration of this corpus-antral boundary. No untoward effect on the cardiac function was observed during stimulation of subdiaphragmatic portion of vagal trunks.
