Evaluation of Gastric Motility with Ultrasonography in Conscious Minipigs

다국어 초록 (Multilingual Abstract)

The purpose of this study is to evaluate gastric motility of conscious minipigs with ultrasonography from
contraction number of the pyloric antrum and gastric emptying time (GET). Five-month-old, clinically healthy minipigs
weighing 13.5-15 kg were used for this experiment. Assessment of gastric motility was performed using saline (10 ml/
kg) in all five minipigs. Contraction number of the pyloric antrum for 3 minutes and gastric emptying time were
calculated. Gastric emptying time was considered to be the time at which the antral area returned to the basal value.
The mean value of contraction number of the pyloric antrum before feeding was 1.60 ± 2.30 (mean ± SD) for 3 min
and the overall mean value after saline administration was 5.40 ± 3.62 for 3 min. The mean value of GET by area
was 58.06 ± 5.23 min. This data can be used as basic database for evaluation of gastric motility in minipigs as normal
and various experimental models.
