Summary

Automatic Translation

Automatic Translation

We developed a new ex vivo model that applies constant tension to the porcine gastric specimen. This development made it possible to evaluate the performance (the height and duration of the submucosal elevation) of various SIMs accurately.  The detailed setup methodology of this new model is explained.
