This leads to the absence of gastric acid production causing compensatory hyperplasia of gastric antral G-cells with hypergastrinemia.10 Furthermore, there is potentially decreased inhibition from gastric D-cells, contributing to increased gastrin production. Usefulness of laparoscope-assisted antrectomy for gastric carcinoids with hypergastrinemia.
