BACKGROUND Spontaneous rupture is rare complication of hepatocellular carcinoma (HCC) with high mortality rate in cirrhotic cases. The aim of this study was to determine the factors influencing prognosis in cases of spontaneously ruptured HCC and to investigate the outcomes of the treatments employed, especially transcatheter arterial embolization (TAE).

BACKGROUND/AIMS Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver injury, and is considered as the hepatic manifestation of metabolic syndrome. However, no effective drug therapy for NAFLD has been established yet. In the present study, we evaluated the efficacy of 4 months of treatment with sitagliptin in NAFLD patients(More)
BACKGROUND Liver fibrosis is the main predictor of the progression of nonalcoholic fatty liver disease. Transient elastography (FibroScan), which measures liver stiffness, is a novel, noninvasive method to assess liver fibrosis. AIM We investigated the usefulness of liver stiffness measurement in the evaluation of liver fibrosis in nonalcoholic fatty(More)
AIM Hepatocellular carcinoma (HCC) is one of the most commonly occurring malignances worldwide. Curative therapies such as resection, percutaneous ethanol injection (PEI) and radiofrequency ablation (RFA) have been applied to patients with early-stage HCC. Patients with more advanced cancers require local or systemic therapies. We present the results of our(More)
AIM To identify the predictive factors for the presence of small bowel lesions in patients with obscure gastrointestinal bleeding (OGIB). METHODS A total of 242 patients with OGIB (overt 149: occult 93) were retrospectively included in the present study. Capsule endoscopy (CE) was carried out to investigate the small bowel, and detected lesions were(More)
PURPOSE Circulating microRNAs (miRNA) are emerging as promising diagnostic biomarkers for colorectal cancer, but their usefulness for detecting early colorectal neoplasms remains unclear. This study aimed to identify serum miRNA biomarkers for the identification of patients with early colorectal neoplasms. EXPERIMENTAL DESIGN A cohort of 237 serum samples(More)
AIM Non-alcoholic steatohepatitis (NASH) is a subset of non-alcoholic fatty liver disease (NAFLD) and sometimes progresses to cirrhosis and liver failure. In this study we analyzed the expression profile of genes and biological pathways involved in NASH in comparison with non-NASH by gene set enrichment analysis (GSEA) employing a DNA microarray technique.(More)
BACKGROUND/AIMS Left-sided diverticulitis is increasing in Japan, and many studies report that left-sided diverticulitis is more likely to be severe. Therefore, it is important to identify the features and risk factors for left-sided diverticulitis. We hypothesized that left-sided diverticulitis in Japan is related to obesity and conducted a study of the(More)
BACKGROUND The prevalence of, and mortality from, colorectal cancer is increasing worldwide, and new strategies for prevention are needed to reduce the burden of this disease. The oral diabetes medicine metformin might have chemopreventive effects against cancer, including colorectal cancer. However, no clinical trial data exist for the use of metformin for(More)
BACKGROUND AND AIMS Chronic intestinal pseudo-obstruction (CIPO) is an intractable disease in which clinical symptoms of intestinal obstruction appear without mechanical cause. No clear diagnostic criteria have been established; therefore, we proposed diagnostic criteria to facilitate the diagnosis of this rare disease and aim to evaluate their usefulness(More)
