Multifocal gastric carcinoid tumors occasionally develop in patients with pernicious anemia, associated with hyperplasia of endocrine cells in the atrophic and metaplastic gastric body mucosa. This constellation of findings probably requires a trophic drive from hypergastrinemia associated with antral G cell hyperplasia, a consequence of achlorhydria in these patients. We report a case in which antrectomy was performed on such a patient in order to abrogate the trophic stimulus. Antrectomy was followed by resolution of hypergastrinemia and a decrease in the size of polyps endoscopically. Nine months later, the gastric remnant was resected. Using morphometric techniques, endocrine cells in the initial antrectomy specimen (which included body mucosa at the resection line) were compared with those in the subsequently removed gastric body. Antrectomy resulted in striking decreases in number (137 versus 34/mm2; P = 0.0001) and size (93 versus 56 microns2; P = 0.0001) of endocrine cells of body mucosa. The findings suggest that antrectomy may be useful in the management of endocrine cell hyperplasia, and possibly also associated carcinoid tumors, in pernicious anemia.
