Whether or not the liver and gallstones can be discharged in one piece depends on the width of the bile ducts and the size of the stone diameter. The width of the common bile duct is about 0.4cm-0.8cm in general, and if the stone is larger than 4mm, it will be difficult to expel the stone in one piece.
The diameter of the common hepatic duct is 0.4-0.6 cm, the diameter of the common bile duct is 0.4-0.8 cm, and the diameter of the cystic duct is 0.2-0.4 cm. The common bile duct opens into the descending part of the duodenum through the duodenal papilla, and it is possible for small stones to be discharged into the duodenum on their own. 4 mm or more stones are difficult to be discharged through the duodenal papillary sphincter, and most of them require surgical treatment.
If the patient finds liver and gallstones, it is recommended to consult the Department of Hepatobiliary Surgery to complete the relevant examinations to determine the size and location of the stones, and then to carry out the appropriate treatment.
