BACKGROUND Recent studies have shown that the combination of proton pump inhibitor, amoxicillin and clarithromycin is one of the best choices for Helicobacter pylori eradication therapy. However, increasing number of cases of H. pylori infection showing resistance to clarithromycin therapy has been reported and this is currently the main cause of(More)
AIM Real-time tissue elastography (RTE) is a non-invasive method for the measurement of tissue elasticity using ultrasonography. Liver fibrosis (LF) index is a quantitative method for evaluation of liver fibrosis calculated by RTE image features. This study aimed to investigate the significance of LF index for predicting liver fibrosis in chronic hepatitis(More)
Superficial esophageal neoplasias resected in piecemeal manner with endoscopic mucosal resection (EMR) sometimes recur locally, and additional treatments need to be developed. Efficacy and safety of endoscopic submucosal dissection (ESD) for esophageal neoplasias are not sufficiently demonstrated, so we conducted a retrospective study to evaluate the(More)
AIM The presence of resistance-associated variants (RAV) may attenuate the efficacy of direct-acting antivirals (DAA) in combination therapy for hepatitis C. The aim of this study was to characterize the NS3 and NS5A regions of hepatitis C virus (HCV) in naturally occurring RAV. METHODS The NS3 and NS5A regions of HCV were amplified by nested polymerase(More)
BACKGROUND A new predictive biomarker for determining prognosis in patients with hepatocellular carcinoma (HCC) who receive sorafenib is required, because achieving a reduction in tumor size with sorafenib is rare, even in patients who have a favorable prognosis. Vascular endothelial growth factor (VEGF) receptor is a sorafenib target. In the current study,(More)
Safety and efficacy of endoscopic submucosal dissection (ESD) for esophageal neoplasias have not been adequately investigated in elderly patients. This study was designed to evaluate the safety and efficacy of ESD for esophageal neoplasias in elderly patients. Fifty-three superficial esophageal neoplasias treated with ESD using a combination of(More)
BACKGROUND The number of sample cases of colonic diverticular hemorrhage treated with endoscopic band ligation (EBL) has been small to date. OBJECTIVE To elucidate the safety and efficacy of EBL for colonic diverticular hemorrhage. DESIGN Retrospective study. SETTING General hospital. PATIENTS A total of 29 patients with 31 colonic diverticula with(More)
We performed a prospective study to evaluate the ability of L-carnitine, which is involved in the β-oxidation of fatty acids, to reduce muscle cramps in patients with cirrhosis. Consecutive patients with cirrhosis and muscle cramps were given L-carnitine 300 mg, 3 times/day (900 mg/day, n = 19) or 4 times/day (1200 mg/day, n = 23) for 8 weeks. The frequency(More)
Large superficial neoplasias of the ileocecal region pose an increased degree of complexity for endoscopic resection. This study aimed to evaluate the safety and efficacy of endoscopic submucosal dissection (ESD) for large superficial colorectal neoplasias including ileocecal lesions. A total of 33 superficial colorectal neoplasias, including eight(More)
Gastrointestinal (GI) carcinoid tumors less than 10 mm in diameter and limited to the submucosal layer demonstrate a low frequency of lymph node and distant metastasis; endoscopic submucosal dissection (ESD) has been used to treat these tumors. However, the number of reported sample cases of rectal carcinoid tumors treated with ESD remains insufficient, and(More)
