Overview
Other diagnostic studies for diagnosis of gastroparesis include 13C-octanoic acid breath test, the SmartPill wireless motility capsule (WMC) system, and electrogastrography. All of them could measure the gastric motility and recognize delayed gastric emptying. Electrogastrography is useful for differentiating gastroparesis from functional dyspepsia by identifying underlying myoelectrical activity.
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][2][3]
- 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.[4]
- It is used to evaluate suspected delayed emptying in gastroparesis and functional dyspepsia by measuring transit time in the stomach, small intestine, and colon.
- It assess both regional and whole gut transit by measuring temperature, pH, and the pressure of its immediate surroundings.[5]
Electrogastrography
- Electrogastrography is used to evaluate gastric electrical activity.[6][7]Schmoldt A, Benthe HF, Haberland G, Sinelnikova EM, Dvoretskova TV, Kagan ZS, Smith RC, Stricker CM, Bricot R, Parry WH, Martorano F, Cotton EK, Cheng HH, Führ F (1975). "Digitoxin metabolism by rat liver microsomes". Biochem. Pharmacol. 24 (17): 1639–41. PMID 10.
- Electrogastrography is useful for differentiating gastroparesis from functional dyspepsia by identifying underlying myoelectrical activity.
- In gastroparesis, motor patterns includes:
- Postprandial antral hypomotility due to infrequent contractions and/or low amplitudes
- Abnormal propagation of antroduodenal contractions
- Increased pyloric spasms which are characterized by an increased tonic and phasic activity
- Abnormal migrating motor complexes (MMC), less frequently originating from the stomach
