BACKGROUND It has been reported that there are four zones of distinct venous patterns around the gastroesophageal junction (GEJ); i.e. truncal, perforating, palisade (PZ) and gastric zones. Using the distal end of PZ as a marker for GEJ, this study was done to assess the length and patterns of PZ in Koreans, and to assess the prevalence of endoscopic(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 Important lesions related to gastroesophageal reflux disease (GERD) are located around the gastroesophageal junction (GEJ). This study examined the distribution of endoscopic findings around the GEJ and elucidated their relationship to each other and esophageal manometric features. METHODS Endoscopic data were collected prospectively from(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)
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)

With the increasing use of pancreatic duct (PD) stents after endoscopic papillectomy (EP), complications such as proximal migration of the stent have become increasingly prevalent. A PD stent that migrates within a nondilated PD may be difficult to remove endoscopically. We performed endoscopic retrieval of proximally migrated PD stents after EP in 5(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)
Small bowel tumors are very rare and generally malignant. As a result of the anatomical location and nonspecific manifestations of small bowel tumors, they are very difficult to diagnose. Balloon-assisted enteroscopy is a relatively noninvasive method compared to surgical resection, and allows for real-time observation, tissue confirmation with biopsy, and(More)
BACKGROUND/AIMS Prothrombin induced by vitamin K defi-ciency or antagonist II (PIVKA-II) is a widely used diagnostic marker for hepatocellular carcinoma (HCC). We evaluated the correlation between alcoholic liver disease (ALD) and serum PIVKA-II levels in chronic liver disease (CLD) patients. METHODS We retrospectively reviewed the medical records of(More)
