We classified cardiac forms observed by inversion-method of endoscope into seven types and analyzed their characteristics in the aged over 60. The total frequency of type I and II, namely the closed type cardia, in the aged is less than in the middle-aged and young. On the contrary, the cases of type IV, V and VI, namely the open type cardia, are more in patients older than 60. We measured the lower esophageal remaining pressure and the lower esophageal sphincter pressure by the use of transducer method. These values in the aged (each -1.6±0.6(SE)cmH2O, 36.9±2.5(SE)cmH2O) are lower than those in the middle and young ages. The remaining gastric pressure of types I and II, and the lower esophageal sphincter pressure of types IV, V and VI are lower in the aged than younger patients. Serum gastrin and secretin value in control group and patients with gastro-dudenal ulcer were examined and the results were compared with age and cardiac forms. Serum gastrin level in the aged patients is lower than that in the middle and young control group and patients with gastro-duodenal ulcer. However, we did not find a significant difference between serum gastrin level and cardiac forms. On the other hand, we found no correlation and significant difference between serum secretin level, and age and cardiac forms.
