Donor safety remains an important concern in living donor liver transplantation (LDLT). In the present study, we assessed recent advancements in the donor operation for LDLT through our experience with this procedure. A total of 886 donor hepatectomies performed between January 1999 and December 2012 were analyzed. Three chronological periods were investigated: the initial period (1999-2004, n 5 239), the period in which the right liver with middle hepatic vein reconstruction was primarily used (2005-2010, n 5 422), and the period in which the right liver with a standardized protocol, including a preoperative donor diet program, an evaluation of steatosis with magnetic resonance spectroscopy, no systemic heparin administration or central venous pressure monitoring, exact midplane dissection, and incremental application of minimal incisions, was exclusively used (2011-2012, n 5 225). The proportion of patients > 50 years old increased (2.5% versus 4.7% versus 8.9%), whereas the proportion of patients with a remnant liver volume 30% (6.5% versus 13.9% versus 6.3%) and with macrosteatosis 10% (7.9% versus 11.1% versus 4.4%) decreased throughout the periods. The operative time (292.7 versus 290.0 versus 272.8 minutes), hospital stay (12.4 versus 11.2 versus 8.5 days), and overall morbidity rate (26.4% versus 13.3% versus 5.8%), including major complications (>grade 3; 1.7% versus 1.9% versus 0.9%) and biliary complications (7.9% versus 5.0% versus 0.9%), were markedly reduced in the most recent period. No intraoperative transfusion was required. No cases of irreversible disability or mortality were noted. In conclusion, the quality of the donor operation has recently been standardized through a large volume of experience, and the operation has been proven to have minimal risk. However, a constant evaluation of our experience is critical for remaining prepared for any unavoidable crisis.
The indication of liver transplantation (LT) for the treatment of advanced hepatocellular carcinoma (HCC) is expanding. However, portal vein tumor thrombus (PVTT) has been still accepted as an absolute contraindication. We experienced an unexpectedly good prognosis in selected patients. Therefore, we tried to identify the prognostic factors after LT for HCC with major PVTT. Among 282 patients who underwent living donor liver transplantation (LDLT) for HCC from January 2009 to December 2013, 11 (3.9%) patients with major PVTT that was preoperatively diagnosed were investigated. The 1-, 3-, and 5-year recurrence-free survival rates were 63.6%, 45.5%, and 45.5%, respectively, and all recurrent cases showed intrahepatic and extrahepatic recurrence. The 1-, 3-, and 5-year overall survival rates were 72.7%, 63.6%, and 63.6%, respectively, and 2 patients with delayed recurrence survived approximately 5 years after LT. Main portal vein (PV) invasion (P < 0.01), high alpha-fetoprotein 3 protein induced by vitamin K absence/antagonist-II (AP) score (20,000; P < 0.01), high standardized uptake value (SUV) ratio (tumor/background liver) in positron emission tomography (2.1; P < 0.01), and a large original tumor (7 cm; P 5 0.03) were significant risk factors for recurrence. In conclusion, if the PVTT has not expanded to the main PV and the AP score is not high, we can consider LDLT as a curative treatment option.
The outcome of LR for HCC was technically feasible and safe in selected patients, and LR showed similar perioperative and long-term oncologic outcomes when compared with OR matched with PSM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
