|---|---|
| Main Objective: Evaluation of UDCA efficacy (versus placebo) after 18 months of therapy, in the complete dissolution of radio-lucent cholesterol gallstones with <15mm of greater diameter, occupying less than half the gallbladder area.;Secondary Objective: Evaluation of the incidence of biliary colic episodes, hospitalization and surgery due to acute cholecystitis or acute episode of chronical cholecystitis, biliary lithiasis, choledocho-lithiasis or biliary pancreatitis, in each group Evaluation of maintenance of response (complete stone dissolution) after a 6-month open trial period without therapy. Evaluation of UDCA treatment safety and tolerability, versus placebo. ;Primary end point(s): Complete dissolution of gallstones, incidence of biliary colic, hospitalization and surgery due to acute cholecystitis or acute episode of chronical cholecystitis, biliary lithiasis, choledocho-lithiasis or biliary pancreatitis, in each group. Maintenance of complete stone dissolution after a 6-month open trial period without therapy. Evaluation of UDCA treatment safety and tolerability, versus placebo. | — |
