| pubmed-article:646042 | pubmed:abstractText | Retained gastric antrum was evaluated in six dogs, and diagnostic methods correlated with histopathology. Secretin and calcium infusion did not significantly alter circulating gastrin levels. 99 mTc scanning was uniformly positive and did not depend on the presence of parietal cells. The failure to consistently develop hypergastrinemia and the absence of gastrin cell hyperplasia suggest that factors other than gastrin may be implicated in the recurrent ulceration seen with retained antrum. | lld:pubmed |
