Gastroesophageal variceal hemorrhage is an important complication of cirrhosis. We investigated the in-hospital mortality and its risk factors after variceal hemorrhage in a large sample population, using a nationwide Japanese database. ⋯ In spite of recent advances in the treatment of variceal hemorrhage, the in-hospital mortality remained as high as 16%. Poor liver function was the most important predictor, suggesting that liver failure after variceal hemorrhage might have been the cause of death.

The nutritional state of living donor liver transplantation (LDLT) recipients is one of the most important factors affecting postoperative outcome. Although the assessment of health-related quality of life (HRQOL) is of increasing importance, few studies have examined this in conjunction with LDLT recipient nutritional state. ⋯ This study demonstrated that the recovery of metabolic function, laboratory data and HRQOL in LDLT recipients are variable, and it took more than 6 months to normalize the liver protein synthetic capacity and physical HRQOL score periods. Therefore, long-term nutritional support is required in LDLT recipients.

Studies have shown that alterations of epigenetics and microRNA (miRNA) play critical roles in the initiation and progression of hepatocellular carcinoma (HCC). Epigenetic silencing of tumor suppressor genes in HCC is generally mediated by DNA hypermethylation of CpG island promoters and histone modifications such as histone deacetylation, methylation of histone H3 lysine 9 (H3K9) and tri-methylation of H3K27. ⋯ We and other groups have demonstrated that important tumor suppressor miRNA are silenced by epigenetic alterations, resulting in activation of target oncogenes in human malignancies including HCC. Restoring the expression of tumor suppressor miRNA by inhibitors of DNA methylation and histone deacetylase may be a promising therapeutic strategy for HCC.

The differing efficacies of radiofrequency ablation and microwave coagulation for hepatocellular carcinoma (HCC) are unknown. Therefore, we performed a multi-center study to assess the factors contributing to survival and local recurrences of HCC among patients with solitary tumors who underwent endoscopic thermal ablation as their primary treatment. ⋯ Differences in the effect on survival and local recurrence between microwave and radiofrequency were not observed in this retrospective, multi-center study of endoscopic thermal ablation for HCC.

Recently percutaneous ethanol injection (PEI) turned into percutaneous radiofrequency ablation (PRFA), and it has become widely used for the treatment of hepatocellular carcinoma (HCC). The present study was to compare the incidence in postoperative HCC recurrence between these two therapeutic approaches. ⋯ The present study demonstrated that PRFA resulted in a lower rate of local recurrence in comparison to conventional PEI, regardless of the operator's experience.
