Overview
Other Diagnostic Studies
Breath Test
- 13C-octanoic acid breath test may be helpful for diagnosis of gastroparesis. Features of breath test in diagnosis of gastroparesis include:[1]
- Determining delayed gastric emptying
- High sensitivity and validity
- Positive correlation to scintigraphy
The SmartPill wireless motility capsule (WMC) system
- The SmartPill is a small device in capsule form that can be swallowed and collects information from the gastrointestinal tract.[2]
- It assess both regional and whole gut transit by measuring temperature, pH, and the pressure of its immediate surroundings.[3]
- It is used to evaluate suspected delayed emptying in gastroparesis and functional dyspepsia by measuring transit time in the stomach, small intestine, and colon.
Electrogastrography
- Electrogastrography is used to evaluate gastric electrical activity.[4][5]
- Electrogastrography is useful for differentiating gastroparesis from functional dyspepsia by identifying underlying myoelectrical activity.
