Rapid Assessment of Donor Liver Quality

Aims： 1. Conduct multi-center, prospective and open research on liver quality assessment and establish LSCM liver quality assessment system 2. Classification of liver quality grades by LSCM for different pathological conditions (steatosis, fibrosis, hepatocyte necrosis, etc.) 3. Compare the specificity and sensitivity of LSCM evaluation results with the results of liver donor quality evaluation and intraoperative pathological biopsy results. 4. LSCM classifies the quality of donor liver and compares the recovery of liver function on the first day after liver transplantation. 5. LSCM grades the quality of donor liver and compares the long-term prognosis
