Bile acids refluxed into the stomach in cases of digestive ulcer were studied. We also studied a relation between results of image process of gastric mucosa using SP-1000 (by Olympus) and concentration of bile acids.
A reflux frequency of bile acids and taurocholic acid into the stomach were the highest in cases of gastric ulcer among digestive ulcers. These concentrations were over twice higher than that of control group (each p<0.01) . We performed image process by electric endoscopic pictures of the posterior wall of the fornix. We got a positive correlation between logarithm of G-signal (log G) and concentration of bile acids (N=55, γ=0.696, p<0.01) .
