Endoscopic retrograde cholangiopancreatography (ERCP)-induced complications, once occurred, can lead to significant morbidity. Commonly 5% to 10% of patients experience procedure related complications such as post-ERCP pancreatitis, biliary hemorrhage, and cholangitis, in descending order. However, complications such as perforation, pneumothorax, air(More)
Oxygen free radicals in excessively high amounts are all very reactive chemically and can impose a detrimental influence on living organisms by provoking "oxidative stress" that can damage major cellular constituents. The latter includes the cell membrane, cytoplasmic proteins, and nuclear DNA. Conversely, nitric oxide (NO), superoxide anion, and related(More)
Despite evidence that Helicobacter pylori (H. pylori) infection is closely associated with stress in gastric ulcer patients, the underlying mechanism why ulcer recurrence after stress is augmented especially in patients with H. pylori remains unknown. In this study, we found that oxidative stress played a critical role in the augmented mucosal damage(More)
A case of multiseptate gallbladder is described, with a review of the literature. This is the 24th such case report. The patient complained of right upper quadrant pain, colicky in nature. Abdominal ultrasonography showed multiple fine echoes within the gallbladder. On endoscopic retrograde cholangiography, multiple radiolucent lines crossing the(More)
BACKGROUND AND AIMS In spite of the International Agency for Research on Cancer's definition that Helicobacter pylori is the definite carcinogen of gastric cancer, the simple eradication of the bug is not enough to prevent resultant gastric cancer, and increasing microbial resistance further limits the eradication application. Therefore, probiotics,(More)
BACKGROUND/AIMS Halitosis is a symptom that bothers patients more socially than medically and its pathogenic mechanisms are unclear and treatment armamenterium is limited. Clinicians generally ignored active interventions. Since halitosis is closely associated with volatile sulfur compounds (VSCs), we used a Halimeter and gas chromatography to measure VSCs(More)
BACKGROUND/AIMS In a previous issue published in Gut and Liver, we found that erosive changes in the esophagogastroduodenal mucosa were strongly correlated with increased levels of volatile sulfur-containing compounds (VSC), suggesting that halitosis could be a symptom reflecting the erosive status of the upper gut mucosa. Together with other studies(More)
OBJECTIVE Gastric carcinogenesis is a multi-step process and is influenced by several etiological agents, including the host's genetic factors. Since whether a patient remains with chronic superficial gastritis (CSG) or progresses to either chronic atrophic gastritis (CAG) or gastric carcinoma (GC) could be a genetic predisposition unique in each(More)
BACKGROUND Quality of life (QOL) in patients with functional dyspepsia in South Korea has never been studied, mostly due to the lack of a psychometrically validated disease-specific instrument for measuring the QOL. The aim of the present study was to develop and validate a QOL scale for patients with functional dyspepsia. METHODS A Functional(More)
BACKGROUND AND AIM Increased resistance of Helicobacter pylori to antibiotics has increased the need to develop new first-line treatments for H. pylori. We have prospectively evaluated 10-day sequential versus conventional triple therapy in peptic ulcer patients. METHODS One hundred and fifty-nine patients with peptic ulcer diseases were prospectively(More)
