Pathophysiological significance of gallbladder volume changes in gallstone diseases

Table 3 Mean fasting, postprandial gallbladder volume and ejection fraction in gallstones patients and normal subjects

	Fasting mean GBV ± SD (cm3) (n)	Postprandial mean GBV ± SD(cm3) (n)	EF ± SD (%) (n)
GS	A31.34 ± 16.46	B20.50 ± 6.201	C34.6 ± 10.6
	(65)	(65)	(65)
Normal subjects	D19.24 ± 11.302	E9.03 ± 3.632	F53.3 ± 24.9
	(53)	(53)	(53)
P-value	< 0.00013	< 0.00014	< 0.00015
(95% CI)	(A-D, 6.93-17.47)	(B-E, 9.56-13.48)	(C-F, 11.9-25.5)

¹P value A vs B < 0.0001, A-B 95% CI: 6.62–15.26;

²P value D vs E < 0.0001; D-E 95% CI: 6.98-13.44;

³P values A vs D: between fasting gallbladder volume (GBV) of chronic cholecystitis and normal subjects;

⁴P values B vs E: between postprandial GBV of chronic cholecystitis and normal subjects;

⁵P values C vs F: between ejection fraction (EF) of chronic cholecystitis and normal subjects. SD: Standard deviation; GS: Gallstones.
