BACKGROUND/AIMS A two-year, prospective, nationwide multicenter study was undertaken to evaluate the effect of Helicobacter pylori eradication on the development of reflux esophagitis (RE) and gastroesophageal reflux disease (GERD) symptoms in the Korean population. METHODS In total, 1,489 subjects without RE were enrolled at the outpatient clinics of 12(More)
The hepatitis B virus (HBV) polymerase gene has overlapping reading frames with surface genes, which allows to alter the amino acid codon of the surface genes. In adefovir (ADV) treated chronic hepatitis B patients carrying rtA181T/rtA181V mutations, overlap with surface gene mutations such as sW172stop/sL173F has been reported. However, the clinical(More)
BACKGROUND/AIMS The use of self-expandable metallic stents (SEMS) is an established palliative treatment for malignant stenosis in the gastrointestinal tract; therefore, its application to benign stenosis is expected to be beneficial because of the more gradual and sustained dilatation in the stenotic portion. We aimed in this prospective observational(More)
PURPOSE Endoscopic resection is widely accepted as standard treatment for early gastric cancer (EGC) without lymph node metastasis. The procedure is minimally invasive, safe, and convenient. However, surgery is sometimes needed after endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) due to perforation, bleeding, or incomplete(More)
BACKGROUND Health-related quality of life (HRQOL) is an important outcome indicator for chronic disease, and particularly in the absence of biological markers for illness, such as with irritable bowel syndrome (IBS). The aims of this study were to develop and evaluate a new IBS-specific HRQOL instrument (IBS-HR-QOL). METHODS This methodological study(More)
BACKGROUND/AIMS To investigate the incidence of cholangiocarcinoma in patients with hepatolithiasis with or without previous resection of liver. METHODS From 2002 to 2009, we retrospectively reviewed 117 patients who were diagnosed and treated for hepatolithiasis in Korea University Guro Hospital. Among the 117 patients, 55 patients who were lost during(More)
which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Photodynamic therapy (PDT) is a unique treatment modality that uses photosensitizers activated by light. Photosensitizers accumulate in malignant tissue, and light energy is used to destroy cancer cells by production of(More)
INTRODUCTION Hiatal hernia (HH) is a well-known contributory factor of gastroesophageal reflux disease (GERD). However, studies on the clinical significance of simple small HH are lacking. We conducted a study to clarify the clinical significance of short segment HH (SSHH) in relation to GERD. METHODS 4,592 consecutive cases (male/female: 2,076/2,516,(More)
Endoscopic resection of gastric subepithelial tumors (SETs) has several advantages over biopsy techniques, such as superior diagnostic yield and definite diagnosis. Removal of gastric SETs and histopathologic confirmation should be considered whenever gastric SETs are highly suspected to have malignant potential such as gastrointestinal stromal tumor (GIST)(More)
