Gallbladder contractility varies significantly day-to-day in healthy individuals. A single measurement of gallbladder contraction may not accurately reflect a person's typical function.

Area of Science:

  • Gastroenterology
  • Radiology
  • Physiology

Background:

  • Gallbladder contractility is measurable via radiological methods.
  • The day-to-day variability of individual gallbladder contractility is not well understood.

Purpose of the Study:

  • To assess the day-to-day variation in gallbladder contractility among healthy individuals.
  • To determine if a single measurement of gallbladder contraction is representative.

Main Methods:

  • Thirty healthy volunteers underwent sonographic assessment of gallbladder volume on three separate occasions.
  • Fasting gallbladder volume and residual gallbladder volume post-fatty meal were measured using the ellipsoid method.
  • Percentage gallbladder contraction was calculated.

Related Experiment Videos

Main Results:

  • Significant day-to-day variations in fasting and residual gallbladder volumes were observed within subjects.
  • Percentage gallbladder contraction varied widely, from 6% to 87% within individuals.
  • In 60% of subjects, contraction values varied by over 20%; in 20%, by over 40%.

Conclusions:

  • There is substantial day-to-day variability in gallbladder contractility in healthy individuals.
  • A single sonographic measurement of gallbladder contraction can be misleading.
  • Repeated assessments may be necessary for accurate evaluation of gallbladder function.
