Body surface area as a surrogate measure of gallbladder sizes and indices : a predictive equation in humans

Abstract EN

Aims: To Find out the relationship between body surface area and gallbladder size; body surface area and gallbladder roundness index; and body surface area and gallbladder spherical index.

Methods: The length, width of 250 normal subjects comprising 140 males were sonographically measured.

The gallbladder volumes, roundness index and spherical index were computed for each subject.

Pearson’s correlation established relationships between body surface area and gallbladder variables.

A regression eq volume and body surface area was computed.

Tests were two statistical significance.

Results: There was a significant linear correlation between gallbladder size and body surface area (r = 0.400; p= 0.00 The correlation between body surface area and gallbladder roundness index (r = area and gallbladder spherical index (r = volume and body surface area based on a simple linear regression gave GBV (cm3) = 32.036 BSA (m2) Conclusion: Body surface area significantly correlates with gallbladder size and hence can be used to predict gallbladder sizes prior to cholecystosonography.

Keywords: Body surface area, gallbladder size, cholecystosonography
