Postoperative survival rates have increased to 90% in 1 year and 80% in 5 years as a result of improvements in immunosuppression, perioperative management and surgical techniques. However, a wide range of postoperative complications are of technical or medical origin. This study was undertaken to determine the relationship between the technical improvements and optimal timing of surgery and its outcome. METHODS: From April 1999 to October 2005, typical orthotopic or piggyback liver transplantation was performed in 70 patients (58 men and 12 women, aged 19-74 years). Twenty-four patients had liver carcinoma and cirrhosis, and 46 had benign liver disease. RESULTS: All patients survived the operation and 14 died in the first month after surgery because of respiratory failure (6), respiratory failure accompanied by acute renal failure (4), intra-abdominal hemorrhage and infection (2), and cerebral edema (2). A total of 76 complications occurred in the 70 patients after operation: pneumonia (34), right pleural effusion (11), bile leakage (7), postoperative intra-abdominal hemorrhage and infection (4), acute renal failure (4), acute rejection (3), wound infection (2), biliary tract stenosis (2), severe cholangitis derived from cholelith (2), morphological alteration of biliary tree (2), cerebral edema (2), empyema (1), chronic rejection (1), and wound hematoma (1). Finally, 33 patients survived more than 6 months, 16 more than 1 year, 4 more than 2 years, and 2 more than 6 years after operation. The perioperative survival rate was 80% in this series.CONCLUSIONS: Liver transplantation is an effective treatment for patients with end-stage liver disease. To obtain good results, improvements of surgical technique, optimal timing and better postoperative care are needed.展开更多

This problem remains worldwide how to choose the optional timing of operation. METHODS:Thirty-six patients with severe hepatitis were treated by orthotopic liver transplantation.The distribution of MELD scores in these patients was:10-19 in 8 patients,20-29 in 10,30-39 in 11,and 40 in 7.They were divided into two groups:MELD score<30 and MELD score≥30.Parameters(1-year survival rate,complications, preoperative use of artificial liver,operative time,volume of bleeding and blood transfusion,and average hospital costs)were examined as prognostic factors after liver transplantation. RESULTS:The 1-year survival rate of the MELD score<30 group was higher than that of the≥30 group(77.8%and 33.3%,P=0.007),and the rate of complications in the<30 group was lower(P=0.012).There were no differencesin the timing of artificial liver treatment,operative time, operative hemorrhage,and transfusion between the two groups(P=0.742).But the average daily hospital cost in the MELD score≥30 group was higher(P=0.008). CONCLUSION:This study shows that when the MELD score is<30 it may be the optimal time to perform liver transplantation for patients with severe hepatitis.展开更多
