Recent studies have shown that circulating microRNAs are a potential biomarker in various types of malignancies. The aim of this study was to investigate the feasibility of using serum exosomal microRNAs as novel serological biomarkers for hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB). We measured the serum exosomal microRNAs and serum circulating microRNAs in patients with CHB (n=20), liver cirrhosis (LC) (n=20) and HCC (n=20). Serum exosomal microRNA was extracted f

BACKGROUND AND AIMS: Epidemiologic studies provide evidence for a link between obesity or diabetes and the risk for colorectal cancer. However, there is a lack of information about the relationship between metabolic syndrome and colorectal adenoma. Therefore, we investigated whether metabolic syndrome is a risk factor for colorectal adenoma. METHODS: We did a study for consecutive subjects who underwent colonoscopy as a screening exam at the Center for Health Promotion, Samsung Medical Center, f

In our cases, we found that P. multiflorum Thunb could be hepatotoxic and could lead to severe drug-induced liver injury, and even death.

BACKGROUND AND AIM: To perform endoscopic mucosal resection (EMR) for T1 esophageal cancer, it is essential to estimate the lymph node status exactly. In order to evaluate the feasibility of EMR for esophageal cancers, we evaluated the clinicopathological features of T1 esophageal squamous carcinomas with an emphasis on the risk factors and distribution patterns of lymph node metastasis. METHODS: From 1994 to 2006, a total of 200 patients with T1 esophageal carcinoma were treated surgically in o

EBD was associated with a higher risk of procedure-related complications than PTBD. These complications were managed properly without severe morbidity; however, in the PTBD group, there were two cases of cancer dissemination along the catheter tract.

The prevalence of musculoskeletal pain in endoscopists is very high. The location of pain was different between beginners and experienced endoscopists. Measures for the prevention and adequate management of endoscopy-related musculoskeletal symptoms are necessary.

BACKGROUND/AIMS: Despite common use of stent-instent methods for endoscopic bilateral metal stenting in malignant hilar obstruction, the longevity of these stents and clinical outcomes of patients who receive them are less well known than for the side-by-side method. We aimed to compare treatment outcomes according to bilateral stenting method. METHODOLOGY: A total of 41 patients were divided into two groups: a bilateral side-by-side metal stenting group (side-by-side group, n=19) and a bilatera

BACKGROUND/AIMS: The rapid urease test (RUT) is an invasive method to diagnose Helicobacter pylori infection, which relies on the acquisition and examination of gastric antrum and body tissues. We determined and compared the efficacy of RUT when the tissues were examined separately or after being combined. METHODS: Two hundred and fourteen patients were included and underwent esophagogastroduodenoscopy from July 2008 to June 2010. The separate test was defined as evaluating the status of infecti

Nonalcoholic fatty liver disease negatively associated with right-hip bone mineral density and serum osteocalcin in Korean men. General population-based prospective studies evaluating the causal relationship between bone metabolism and nonalcoholic fatty liver disease are needed, and the mechanism linking nonalcoholic fatty liver disease to bone mineral density beyond insulin resistance and osteocalcin should be evaluated in the future.

A comparison of the risk factors of proximal and distal colorectal cancer showed that Type 2 diabetes is associated with distal colorectal cancer in males and that cholelithiasis is associated with proximal colon cancer in females.

Pyogenic liver abscess (PLA) is a severe disease with considerable mortality and is often polymicrobial. Understanding the pathogens that cause PLA is the basis for PLA treatment. Here, we profiled the bacterial composition in PLA fluid by pyrosequencing the 16S ribosomal RNA (rRNA) gene based on next-generation sequencing (NGS) technology to identify etiological agents of PLA and to provide information of their 16S rRNA sequences for application to DNA-based techniques in the hospital. Twenty p

Use of oral antiviral treatment after curative RF ablation was associated with favorable outcomes in terms of tumor recurrence and overall survival in patients with HBV-related HCC.
