Gallbladder contractility and volume characteristics in gallstone dyspepsia

Figure 1 Gllbladder volume change after ingestion of 500 mL of normal saline (N. S.) in healthy volunteers (normal controls, n = 10), group I (symptom free or symptom improved after cholecystectomy) (n = 40) and group II (persistent dyspepsia af-ter cholecystectomy) (n = 22) gallstone patients. Values are mean ± SE (Χ² test). ^aP < 0.05: significant volume change from fasting gallbladder volume. ^cP < 0.05: significant difference among three groups (group I vs normal group and group II patients).
