Implication
Scintigraphy may detect more antral contractions than manometry; leaves open whether combined use improves evaluation in patients.
Structured PICO
Does scintigraphy compare favorably with manometry for evaluating antral motility in healthy volunteers?
P
Population
9 healthy volunteers
I
Intervention
Simultaneous scintigraphic and manometric measurements of antral motility after ingesting a test meal (100 g minced beef labelled with 100 MBq 99mTc-chicken liver and 150 ml water)
C
Comparator
Comparison between scintigraphy and manometry
O
Outcome
Antral motility (contraction rates, amplitude of wall motion, and pressure waves)surrogate
Scintigraphy detects antral wall motion with greater sensitivity than manometry, particularly in the proximal antrum, suggesting the combination of both techniques shows promise for evaluating antral motility.
