Liver morphology is irregular and the perimetrium is not smooth, which indicates that there is substantial damage to the liver. Long-term damage to the liver cells will lead to degeneration and necrosis of the liver cells. Relevant tests should be carried out in time to see if there is hepatitis B or C. If hepatitis B or C is negative, it is considered to be related to the long-term use of drugs, and it is recommended to check whether the liver function is abnormal. There may be other reasons for the irregular liver morphology and lack of smoothness of the periphery, which should be further examined in time and treated under the guidance of a doctor.
