Gallbladder stones are mainly cholesterol stones, which are related to the cholesterol metabolism of the liver. The increase of cholesterol content and the decrease of bile acid salt content in the bile secreted by the liver are related to the formation of stones. In addition, new methods such as choledochoscopy and mesh basket extraction, which are very traumatic to the gallbladder, avoid damage to the gallbladder mucosa, avoid residual stones, and use absorbable sutures, can effectively reduce the recurrence of stones caused by surgery compared to traditional surgery.
