[Gastric emptying in patients with chronic gastritis. Its relation to serum gastric levels].

Forty eight patients were evaluated to ascertain a correlation (if any) between gastric acid secretion, fasting and post prandial serum gastrin levels, gastric biopsy (antrum and fundus) and gastric emptying time after a standard test meal. The following conclusions were obtained: a) 57.8% of patients with atrophic gastritis and achlorhydria had evaluated serum gastrin levels; b) most patients with high gastrin levels had normal antrum on biopsy or showed only minimal inflamatory changes, while those with normal gastrin levels disclosed more pronounced histological changes; c) patients with achlorhydria had slower gastric emptying rates, and this was more evident among those with higher gastrin levels (though differences were not statistically significant).
