The gastric barostat study is the gold standard method for evaluating gastric perception and accommodation. This technique has serious drawbacks, such as expense and invasiveness. Several drinking tests have been developed as noninvasive methods. Such tests are easily performed without special instruments and are well tolerated. We have reported that (1) a threshold volume inducing mild bloating in the slow nutrient drinking test might be an alternative parameter of gastric accommodation volume as determined by the barostat method and (2) the maximum satiety volume in the drinking test correlated positively with the pressure to induce severe discomfort in healthy volunteers, indicating that the slow nutrient drinking test may be useful for evaluating accommodation volume and the threshold to induce severe discomfort. However, the correlation between the maximum satiety drinking volume and accommodation volume as measured by the barostat study has been controversial.Therefore, validation of a certain nutrient drink test for measuring gastroduodenal function might be recommended in each institution.
