An important component of the enterohepatic circulation is the active reabsorption of conjugated bile acids in the terminal ileum, with special reference to bile acid pool size that may be defined as the total mass of bile acids in the enterohepatic circulation. However, because of technical difficulties in measuring of bile acid pool size in human being, the role of the bile acid pool has little been investigated, and the exact mechanism of change in bile acid pool size has not yet been clear. Therefore, were there two changes of small intestinal motility and bile acid pool size in cholesterol gallstone patients？ and, if so, was there correlated relationship between both alterations require further investigation？展开更多
