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)
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).

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)
BACKGROUND The differences in the small intestinal toxicity of low-dose aspirin based on the type of aspirin used remains unclear. The purpose of this study was to evaluate the differences in the small bowel mucosal injury between buffered and enteric-coated aspirin users by capsule endoscopy. METHODS We retrospectively reviewed the findings in chronic(More)
Few studies have investigated measures to prevent small bowel injuries induced by aspirin. Our aim was to evaluate the effect of probiotic treatment on the small bowel injuries induced by chronic low-dose aspirin use. Thirty-five patients who took low-dose enteric-coated aspirin 100 mg daily (for more than 3 months) plus omeprazole 20 mg daily and were(More)
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)
AIM The major limitation of capsule endoscopy (CE) has been the lack of a standardized and validated severity scale for mucosal injury. The aim of the present study was to verify the usefulness of quantifying small bowel mucosal changes associated with giving low-dose aspirin (LDA) using a CE scoring index. METHODS The CE score for small bowel mucosal(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)
