Pathophysiological significance of gallbladder volume changes in gallstone diseases

Table 1 Demographic data and gallbladder volume in gallstone and non-gallstone subjects

Variables diagnosis	M/F	Mean age (yr)	Mean GBV (cm3) (n)	SD (cm3)	P-value (95% CI1)
Acute	D53/462	57 ± 17	A57.00	41.20	0.00043
Cholecystitis			(99)		(7.73-26.35)
Chronic	32/53	53 ± 15	B28.77	15.00	< 0.00014
Cholecystitis			(85)		(8.14-15.86)
Contracted		44 ± 21	6.15	2.52
Gallbladder	1/4		(5)
Non-gallstone		54 ± 18	C16.77	15.75
	E39/41		(240)	-

¹95% CI of gallbladder volume (GBV) difference;

²P value D vs E = 0.04, between gender of acute and chronic cholecystitis;

³P value A vs B: between GBV of acute and chronic cholecystitis;

⁴P value B vs C: between chronic cholecystitis and non-gallstone subjects. SD: Standard deviation.
