We aimed to validate the prognostic predictive power of ADV score (α-FP-des-γ-carboxyprothrombin [DCP]-tumor volume [TV] score, calculated as α-FP [ng/mL] × DCP [mAU/mL] TV [mL] and expressed in log10) for predicting patient survival after resection hepatocellular carcinoma (HCC).This study included 1,390 patients with HCC registered Korea Liver Cancer Registry. Patients underwent hepatic between 2008 2012 were followed up until December 2016. They divided into 4 groups according number...
The mammalian target of the rapamycin inhibitor has dual inhibitory effects on cell growth and angiogenesis. This study aimed to analyze usage everolimus actual immunosuppression (IS) regimens through a cross-sectional in high-volume liver transplantation (LT) center.Our institutional LT database was searched for adult patients who underwent primary surgery between January 2010 December 2016. We identified 2,093 recipients with observation periods 1 8 years.We divided into three groups...
Malignant intraductal papillary neoplasm of the bile duct liver (IPNB-L) cannot readily be diagnosed through preoperative CT or MRI, but fluorodeoxyglucose (FDG)-PET is a viable alternative. This study evaluated diagnostic and prognostic impacts FDG-PET in patients with IPNB-L.This was retrospective single-center 101 IPNB-L who underwent hepatectomy between 2010 2019.Mean age 64.4 ± 8.3 years 76 (75.2%) were male. Anatomical hepatic resection performed 99 (98.0%). Concurrent...
Backgrounds/Aims Prevention of excessive bleeding during liver transplantation (LT) operations presents a major challenge. Compared to deceased donor LT, living LT (LDLT) is more vulnerable because additional dissection procedures. We herein introduce our technique for prolonged occlusion the hepatoduodenal ligament applied recipient hepatectomy LDLT. Methods Simulated assessment splanchnic hemodynamics on showed that patients with cirrhotic appeared tolerate procedure as like in normal...
Background: Hepatocellular carcinoma (HCC) recurrence and development of de novo malignancy (DNM) after liver transplantation (LT) are the major causes late recipient death.Methods: We analyzed incidence extrahepatic DNM following living donor LT according to status pretransplant hepatic malignancy.We selected 2,076 adult patients who underwent primary LDLT during 7 years from January 2010 December 2016.Results: The group (n = 1,012) showed 45 cases (4.4%) DNMs: posttransplant...
Prophylaxis for hepatitis B virus (HBV) recurrence is essential after liver transplantation (LT) in HBV-associated recipients. This study established an individualized HBV prophylaxis protocol, through optimization of immunoglobulin (HBIG) administration, with application simulative half-life (SHL). involved five parts: Part 1 developed the SHL estimation method 20 patients; Parts 2 and 3 assessed variability a simulation model to apply 100 4 validated 114 patients, 5 was cross-sectional on...
