Decreased postprandial gallbladder emptying in patients with black pigment stones

Figure 6 Postprandial contractility indices of the gallbladder according to the reflux state of a radioisotope into the common hepatic duct. In normal subjects, EF was significantly larger in patients with reflux. In a subgroup analysis of such patients, EF and ER in those with either CSs or BPSs showed a significant reduction in comparison to those in normal subjects. ^aP < 0.05, ^bP < 0.01.
