Plasma neurotensin response to oral glucose in patients with and witho
ut early dumping syndrome after gastrectomy was investigated with oral
glucose load (50g). 5 patients with early dumping syndrome and 8 pati
ents without the syndrome were investigated before and after gastrecto
my. There was no difference in response of neurotensin before surgery
between these two groups of patients. Plasma levels of neurotensin aft
er gastrectomy were significantly higher than those before gastrectomy
. Plasma neurotensin response to oral glucose in patients with dumping
syndrome did not differ from that without dumping syndrome. These res
ults suggest that it is unlikely that neurotensin has a significant ro
le in the early dumping syndrome in gastrectomized patients.
