| Outline of Final Research Achievements |
The functional gastrointestinal disorders (FGID) are common in daily practice. Their pathophysiology includes impaired gastrointestinal motility and distention. World standard test for FGIDs requires specialized equipment and is rarely used in Japan. We previously developed technique of 3-D measurements using stereo endoscopy which mounted a compound eye system. Here, we examined its basic specification for measuring gastrointestinal function. Major findings are as follows. Stereo endoscope measured the movement of peristaltic wave which was set to 2 mm/s as 1.74 mm/s (13% error). Stereo endoscope measured the diameter of a cylinder which was built 20 mm in diameter as 19.6 mm (3% error) and the volume of a half-sphere which was built 20 mm in diameter as 1.9mm3 (theoretical value 2.09, 9% error). These findings demonstrate the potential of our stereo endoscopy to measure the gastrointestinal function precisely.
