Laparoscopic liver resection (LR) for hepatocellular carcinoma (HCC) is usually applied to superficial and left-side small lesions. Therefore, well designed comparative studies about the results of LR versus open liver resection (OR) for HCC are difficult and still uncommon. The aim of this study was to compare the perioperative and long-term oncologic(More)
BACKGROUND Laparoscopic treatment for gallbladder cancer (GBC) has long been contraindicated, but few studies have demonstrated the oncologic outcomes of this treatment. The purpose of this study was to evaluate long-term survival after intended laparoscopic surgery for early-stage GBC based on our 10 years of experience. STUDY DESIGN Between May 2004 and(More)
BACKGROUND Although transarterial chemoembolization is recommended as the standard treatment for Barcelona Clinic Liver Cancer stage B hepatocellular carcinoma (BCLC-B HCC), other treatments including liver resection have been used. This study aimed to determine the survival benefit of treatment strategies including resection for BCLC-B HCC compared with(More)
BACKGROUND Laparoscopic liver resection is an attractive option for treating liver tumors. Laparoscopic liver resection is more difficult for hepatocellular carcinomas located in the posterosuperior segments than for hepatocellular carcinomas in the anterolateral segments. We compared perioperative and long-term outcomes between laparoscopic liver resection(More)
OBJECTIVE To evaluate the influence of the anatomy of the right posterior bile duct (RPBD) of the donor on biliary complications in the recipients after living-donor liver transplantation (LDLT) using right hemi-liver grafts. BACKGROUND DATA During living-donor right hepatectomy, the RPBD was often exposed to the dissection plane. We hypothesized that(More)
BACKGROUND There is increasing interest in hepatocellular carcinomas (HCC) expressing "stemness"-related markers, as they have been associated with aggressive behavior and poor prognosis. In this study, we investigated the usefulness of Sal-like protein 4 (SALL4), a recently proposed candidate marker of "stemness." METHODS Immunohistochemical stains were(More)
The initial abdominal computed tomography (CT) scans of patients with colorectal cancer (CRC) sometimes reveal equivocal hepatic lesions. In this study, we evaluated the outcomes of equivocal hepatic lesions found by abdominal CT and the diagnostic accuracy of subsequent liver magnetic resonance imaging (MRI). We evaluated data of patients who underwent CRC(More)
BACKGROUND/AIMS The most commonly used immunosuppressant therapy after liver transplantation (LT) is a combination of tacrolimus and steroid. Basiliximab induction has recently been introduced; however, the most appropriate immunosuppression for hepatocellular carcinoma (HCC) patients after LT is still debated. METHODS Ninety-three LT recipients with HCC(More)
PURPOSE We evaluated the heterogeneity of steatosis in living donor livers to determine its regional differences. METHODS Between June 2011 and February 2012, 81 liver donors were selected. Fat fraction was estimated using magnetic resonance triple-echo chemical shifting gradient imaging in 13 different regions: segment 1 (S1), S2, S3, and each peripheral(More)
