Study on gallbladder emptying function in the asymptomatic gallstone patients.

Objective To investigate gallbladder emptying function in the asymptomatic gallstone patients. Methods 20 patients with asyptomatic gallstone and 10 normal were selected, Gallbladder volume were measured by B urtrasounography and calculated by ellipse formula during different time phages. Results The gallbladder motility were impaired in gallstone patients, FV and RV in gallstone patients were higher than these in controls, E in gallstone patients was lower than these in controls. The patients were divided into two groups by the limit of RF+2SD. Conclusions The gallbladder emptying were significantly impaired in asymptomatic gallstone patients.
