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 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)
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 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 To develop appropriate management strategies for patients who take low-dose aspirin, it is important to identify the risk factors for GI injury. However, few studies have described the risk factors for small-bowel injury in these patients. OBJECTIVE To investigate factors influencing the risk of small-bowel mucosal breaks in individuals taking(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)
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)
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 To reveal the frequency, characteristics and prognosis of chronic intestinal pseudo-obstruction (CIP) in mitochondrial disease patients. METHODS Between January 2000 and December 2010, 31 patients (13 males and 18 females) were diagnosed with mitochondrial diseases at our hospital. We conducted a retrospective review of the patients' sex, subclass of(More)
In experimental models, mucin-depleted foci (MDF), formed by dysplastic crypts devoid of mucin production have been recognized to be correlated with colorectal carcinogenesis and to serve as preneoplastic lesions of colorectal cancer (CRC). In humans, there is only one report of identification of MDF in patients with familial adenomatous polyposis and CRC;(More)
