Liver transplantation at a small-volume procedure center - Preliminary results from Taipei veterans General Hospital

Background: Liver transplantation is a challenging procedure that is associated with perioperative morbidity and mortality, so it is justifiable to perform such a procedure in high-volume procedure centers. Organ shortage remains a major issue in Taiwan. Due to the difficulty in establishing a high-volume procedure center, it is important to review the overall outcome of patients undergoing liver transplantation at a small-volume procedure center to determine if performing such a procedure is justified. Methods: Between April 2001 and May 2005, 26 adults underwent deceased donor liver transplantation at Taipei Veterans General Hospital. The overall outcomes were reviewed in terms of 90-day mortality, 1-year and 3-year survival rates. In addition, the patients were divided into a hepatocellular carcinoma (HCC) group (n=12) and a benign end-stage liver disease (ESLD) group (n=14). The clinical demographics, 90-day mortality, 1-year and 3-year survival rates were reviewed and compared between the 2 groups. Results: The 90-day mortality was 15.3% in the whole series, 8.3% in the HCC group and 18.7% in the ESLD group. The overall 1-year and 3-year survival rates were 76.9% and 63.5%, respectively, for the whole series. For the 2 groups, the respective 1-year and 3-year survival rates were 83.3% and 71.4% in the HCC group, and 71.4% and 57.1% in the ESLD group. The survival difference was not significant (p=0.319) between the 2 groups. In the HCC group, the 1-year and 3-year disease-free survival rates were 88.9% and 71.1%, respectively. Conclusion: The survival rates between ESLD and HCC patients undergoing liver transplantation at a small-volume procedure center were comparable. The results of the whole series were not satisfactory, but the results for the HCC group were acceptable.
