胆囊在胆结石形成中起重要作用,故有必要了解胆囊及其与胆汁的相互作用。虽然源生于肝脏的胆固醇饱和性胆汁(称成石性胆汁)是胆结石形成的先决条件,但成石性胆汁也常存在于正常人,因而在胆汁或胆囊粘膜中肯定存在另一些因素。其中之一就是胆囊内胆汁的钙浓度。许多研究表明,在胆固醇或色素性胆结石患者,其胆汁中的钙常常是超饱和的,所以钙易沉淀。极大多数结石含有由钙酸盐组成的核心。当结石增大时,围绕核心沉积多层胆红
Gallbladder plays an important role in the formation of gallstones, so it is necessary to understand the gallbladder and its interaction with bile. Although cholesterol-saturated bile (liver stone called bile), which originates from the liver, is a prerequisite for the formation of gallstones, fossilized bile usually exists in normal people and there are certainly other factors in the bile or gall bladder mucosa. One of them is the calcium concentration in gallbladder bile. Many studies have shown that in patients with cholesterol or pigment gallstones, calcium in the bile is often supersaturated, so calcium is easy to precipitate. Most stones contain the core of calcium salts. When the stone increases, around the core deposition of multi-layer bile red
