BACKGROUND & AIMS Data on the association between erosive esophagitis and obesity are inconsistent because of variations in study populations and methods used to determine obesity. METHODS Participants in a prospective health-screening cohort underwent esophagogastroduodenoscopy and computed tomography. The association between erosive esophagitis and(More)
OBJECTIVES We evaluated the association between current Helicobacter pylori infection and reflux esophagitis and the effect of H. pylori eradication on reflux esophagitis in a healthy screening population. METHODS A total of 10,102 subjects in a comprehensive screening cohort were enrolled, and 4,007 subjects had follow-up after a median of 2 years.(More)
BACKGROUND & AIMS Small studies have shown inconsistent results regarding the association between abdominal visceral adipose tissue and colorectal adenomas. We evaluated the effects of visceral adipose tissue volume on the development and growth of colorectal adenomas. METHODS A total of 3922 participants underwent colonoscopy and computed tomography from(More)
Vaccination against hepatitis A virus (HAV) is recommended for patients with chronic liver disease (CLD), but this has been deemed unnecessary in Korea since the immunity against HAV was almost universal in adults. However, this practice has never been reevaluated with respect to the changing incidence of adult acute hepatitis A. We retrospectively reviewed(More)
BACKGROUND/AIMS Although several studies have suggested overlaps between gastroesophageal reflux symptom and irritable bowel syndrome (IBS), the studies for the association between erosive esophagitis and IBS are rare. The aim of this study was to evaluate the association among IBS, non-erosive reflux disease (NERD), and erosive esophagitis. METHODS A(More)
Ischemic colitis is a condition that usually occurs in the elderly, as a form of vascular disease. However, ischemic colitis also occurs, though rarely, in healthy young adults. Moreover, food supplements containing Ephedra sinica or ma huang have been linked to adverse central nervous and cardiovascular events. A 40-year-old man was admitted to our(More)
BACKGROUND/AIMS Although adipocytes secrete inflammatory cytokines and adipokines, their role in reflux esophagitis is controversial. We investigated the association between visceral fat and inflammatory cytokines or adipokines in reflux esophagitis. METHODS Abdominal visceral fat and cytokines were measured in 66 individuals with reflux esophagitis and(More)
The objective of this study is to determine whether targeted colonoscopy skills are acquired through simulation-based training using the KAIST-Ewha Colonoscopy Simulator II, and the acquired skills can be transferred to colonoscopy to actual patients. Eleven subjects consisting of six fellows and five residents participated in the study. The fellows and(More)
Recently, some studies have shown that diabetes mellitus and metabolic syndrome increase the risk of colorectal neoplasms. Although the mechanism is not known, those have been proposed to contribute to this phenomenon, including insulin resistance, oxidative stress, and adipokine production. The objective of this study was to assess the association between(More)
Cytomegalovirus enteritis is most usually associated with patients positive for human immunodeficiency virus or immunosuppressed transplant patients. The gastrointestinal tract may be affected anywhere from the esophagus to the colon, but the small bowel involvement is rare. We report a case of cytomegalovirus ileitis in an immunocompetent adult, which was(More)
