Background/Aims: Snoring is the sound of turbulence and vibration of the upper respiratory tissues and has been identified as a risk factor of obstructive sleep apnea (OSA) and cardiovascular disease. The aim of this study was to identify associated clinical factors in snoring patients undergoing se..
Background/Aims: A number of clinical trials reported varying effects of cholesterol lowering agents in nonalcoholic fatty liver disease (NAFLD) patients. We, therefore, assessed the changes in hepatic steatosis and NAFLD activity score (NAS) after treatment with cholesterol lowering agents in NAFLD..
Background/Aims: Selecting patients with an urgent need for endoscopic hemostasis is difficult based only on simple parameters of presumed acute upper gastrointestinal bleeding. This study assessed easily applicable factors to predict cases in need of urgent endoscopic hemostasis due to acute upper ..
Background/Aims: The Crohn’s and Colitis Knowledge (CCKNOW) score does not reflect updated knowledge relating to inflammatory bowel disease (IBD). The aim of this study was to develop, validate, and apply a novel tool to measure disease-related knowledge in IBD patients.
Methods: A questionnaire ..
Background/Aims: Fecal calprotectin (FC) is known to correlate with disease activity and can be used as a predictor for relapse or treatment response in inflammatory bowel disease (IBD). We evaluated the usefulness of FC as a biomarker for disease activity in patients with IBD using both enzyme-link..
Background/Aims: There are few comparative studies on the historical changes in the clinicopathologic characteristics of colorectal polyps in Korea. This retrospective study compared the clinicopathologic characteristics of colorectal polyps treated at our institution in 2002 and 2012.
Background/Aims: Several epidemiological studies have validated the association of interleukin gene polymorphisms with acute pancreatitis (AP) in different populations. However, there have been few studies in Asian ethnic groups. We aimed to investigate the relationships between inflammatory cytoki..
Background/Aims: The aim of this study was to investigate parameters that predict radiation-induced liver disease (RILD) following stereotactic body radiotherapy (SBRT) in patients with hepatocellular carcinoma (HCC) and to identify the clinical significance of RILD.
Methods: We retrospectively rev..
Background/Aims: There has been no evidence for the necessity of endoscopy in asymptomatic young men with iron deficiency anemia (IDA). To determine whether endoscopy should be recommended in asymptomatic young men with IDA, we compared the prevalence of gastrointestinal (GI) lesions between young m..
Background/Aims: E-health technologies have been implemented for the management of Crohn’s disease (CD). We aimed to identify differences between patient activities at home and at routine clinic visits using a web-based self-reporting CD symptom diary (CDSD) and to determine the impact of this dis..
Background/Aims: In countries with a higher risk of gastric atrophic gastritis, noninvasive tests are helpful for a more reliable diagnosis of Helicobacter pylori infection. The aim of this study was to evaluate the characteristics of seropositive subjects according to their stool H. pylori a..
Background/Aims: Endoscopic ultrasound-guided fine needle aspiration (EUSFNA) and brushing cytology are used worldwide to diagnose pancreatic and biliary malignant tumors. Liquid-based cytology (LBC) has been developed and it is currently used to overcome the limitations of conventional smears (CS)...
Background/Aims: Biliary complications are the most common donor complication following living donor liver transplantation (LDLT). The aim of this study is to investigate the long-term outcomes of biliary complications in right lobe adult-to-adult LDLT donors, and to evaluate the efficacy of endosco..
Background/Aims: The aim of this study was to investigate the mortality, bleeding control rate, and their associated predictors in patients treated with Sengstaken-Blakemore (SB) tube for uncontrolled variceal hemorrhage associated with hemodynamic instability or failure of endoscopic treatment.
Background/Aims: Western guidelines recommend Helicobacter pylori eradication in H. pylori-associated gastric polyps; however, there is no standard guideline in Korea. The aim of this study is to assess the effect of H. pylori eradication on the regression of gastric hyperplasti..
Background/Aims: The aim of this retrospective study was to assess the efficacy of percutaneous cholecystostomy (PC) for patients with acute cholecystitis (AC) according to severity.
Methods: A total of 325 patients who underwent cholecystectomy between January 2008 and October 2010 were enrolled. ..
Background/Aims: Gastrointestinal (GI) bleeding is a life-threatening complication in critically ill patients. The aim of this study was to determine the efficacy of bedside endoscopy in an intensive care unit (ICU) setting, and to compare the outcomes of early endoscopy (within 24 hours of detectin..
Background/Aims: The gastroesophageal junction is an important barrier against gastroesophageal ref lux. Endoscopic grading of gastroesophageal f lap valve is simple, reproducible, and may predict reflux activity. We investigated the correlation between gastroesophageal flap valve grade and the gast..
Background/Aims: Entecavir (ETV) is effective and safe antiviral agent against hepatitis B virus (HBV) in clinical and real-world setting but, most studies were performed in single institute or have limitation in patient’s number. A large-scale nation-wide real-world surveillance study was carried..
Background/Aims: Nucleotide-binding oligomerization domain 1 (NOD1) is required for primary intestinal epithelial cells (IECs) to respond to natural mucopeptides secreted by gram-negative bacteria. Infection of human IECs with invasive bacteria up-regulates intercellular adhesion molecule-1 (ICAM-1)..
