Liver trauma refers to liver injury caused by different types and degrees of trauma to the liver. Liver trauma is caused by more serious trauma to the abdomen, such as sharp instruments to the abdomen, such as stabbing with a knife or sword. Or by blunt force, such as the abdomen by the blow, car accident impact, extrusion, explosion shock injury. Because the liver is relatively fragile, it is easier for the liver to be affected after trauma to the body. Because the liver is rich in blood flow, traumatic damage to the liver can easily cause abdominal bleeding. Moreover, there are intrahepatic bile ducts in the liver, if the bile ducts rupture due to external force, the bile in the bile ducts will also cause cholestatic peritonitis if it enters into the abdominal cavity. When liver trauma occurs, it is necessary to consult a doctor in time, improve the imaging examination, make a clear diagnosis, and give standardized treatment in time.
