Duodeno-gastric reflux and gastric adenomas: a scintigraphic study in patients with familial adenomatous polyposis.


To test whether the presence of gastric adenomas (dysplasia) was associated with gastric reflux of duodenal contents, six patients with familial adenomatous polyposis (FAP) who had gastric adenomas and nine matched FAP patients without gastric adenomas underwent scintigraphic duodeno-gastric reflux scanning. Reflux was graded 0-6, where 0 = no reflux, 1 = intermittent reflux into antrum only, 2 = prolonged reflux into antrum only, 3 = intermittent reflux into body, 4 = prolonged reflux into body, 5 = intermittent reflux into body and fundus, and 6 = prolonged reflux into body and fundus. FAP patients with gastric adenomas had more severe reflux (median 6, range 4-6) than did controls (median 3, range 0-6; P = 0.009, Mann-Whitney U test). These results are consistent with a role for bile in the development of gastric adenomatous polyps and suggest that bile is involved in the dysplasia-carcinoma sequence.
