AIM:To compare the effectiveness of sequential therapy for Helicobacter pylori (H.pylori ) infection with that triple varying durations. METHODS:The 460 patients enrolled in this study had H. -associated gastritis or a gastric duodenal ulcer.After screening, -infected were randomly assigned to receive either conventional 7, 10 14 d, new 10-d therapy.Each 4 treatment groups included 115 patients.The outcomes eradication assessed wk after by urea breath test and histology. RESULTS:The overall...
There has been a long-standing expectation that the optical-resolution embodiment of photoacoustic tomography could have substantial impact on gastrointestinal endoscopy by enabling microscopic visualization vasculature based endogenous contrast mechanism. Although multiple studies demonstrated in vivo imaging capability developed device over last decade, implementation such an endoscopic system can be applied immediately when necessary via instrument channel video endoscope challenge. In...
It remains unclear whether the currently-used normal range for serum alanine aminotransferase (ALT) levels really reflects a healthy liver. The present study was conducted to evaluate of ALT in Korean adult population and determine clinical significance unhealthy levels.We reviewed medical records, including questionnaires results laboratory radiological tests at Health Promotion Center Korea University Anam Hospital between March 2005 February 2007. written questionnaire form, included...
To suggest a new cleansing score system for small bowel preparation and to evaluate its clinical efficacy.Twenty capsule endoscopy cases were reviewed was assessed with the scoring system. For assessment, two visual parameters used: proportion of visualized mucosa degree obscuration. Representative frames from images serially selected scored at 5-min intervals. Intraclass correlation coefficient (ICC) obtained assess reliability efficacy evaluation validation, scores our compared another...
Diversion colitis is the inflammation of excluded segment colon in patients undergoing ostomy. It has been suggested that a change colonic flora may lead to colitis; however, direct evidence for this disease progression lacking. The aim study was evaluate relationship between severity diversion and composition bacteria.We used culture methods polymerase chain reaction analyze microflora who underwent rectal cancer resection with or without ileostomy. In group, we also evaluated colonoscopic...
Patients with type II diabetes mellitus (DM) were known to have higher prevalence of gastroesophageal reflux disease (GERD). Recent studies shown that neuropathy has positive role on the development GERD in DM, although its pathogenesis not been fully understood yet. The aim this study was investigate whether really contribute and typical symptoms patients DM Korea.
Background/Aims Inflammatory bowel disease (IBD) management guidelines have been released from Western countries, but no adequate data on the application of these in Asian countries and surveys treatment IBD real practice exist. Since there is a growing need for customized consensus Organization Crohn's Colitis performed multinational survey medical doctors who treat patients countries. Methods A questionnaire was developed between August 2013 November 2013. It composed 4 domains: personal...
Although the Psychometric Hepatic Encephalopathy Score (PHES) for diagnosis of minimal hepatic encephalopathy (MHE) has been validated in several countries, further validation is required its use different populations. The aims this study were thus to standardize PHES a healthy Korean population and evaluate prevalence MHE among patients with liver cirrhosis.Two-hundred subjects without evidence disease 160 cirrhosis overt HE included. Blood sampling routine laboratory tests determination...
AIM:To investigate whether suspected blood indicator (SBI) in capsule endoscopy (CE) is affected by background color and passage velocity. METHODS:Experimental models of the small intestine constructed from paper a variety colors were used to simulate observed CE images.The studied included very pale yellow, magenta, light grayish pink, burnt sienna, deep dark brown, red spots attached inside them.An endoscopic was manually passed through models.The rate detection SBI evaluated based on...
Background and Aim: Low-volume polyethylene glycol with ascorbic acid (PEG-Asc) use is reported to be as safe effective traditional 4-L use. However, PEG-Asc produces bubbles, which cause problems during colonoscopy. Data on the effects of using antifoaming agents such simethicone are lacking. The aim this CONSORT-prospective, randomized, observer-blinded, controlled trial compare quality bowel preparation compliance between users plus users. Methods: Adult outpatients aged 18 80 years...

AIM:To evaluate the value of systemic inflammationbased markers as prognostic factors for advanced pancreatic cancer (PC). METHODS:Data from 82 patients who underwent combination chemotherapy with gemcitabine and erlotinib PC 2011 to 2014 were collected retrospectively.Data that included neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, C-reactive protein (CRP)-to-albumin (CRP/Alb) analyzed.Kaplan-Meier curves, univariate multivariate Cox proportional hazards regression...
Intestinal mucositis is a commonly encountered complication of chemotherapy. However, there are few effective treatments or preventive methods. Ursodeoxycholic acid (UDCA) stabilizes cell membranes, acts as an antioxidant and inhibits apoptosis, thereby exerting cytoprotective effects. The aim the present study was to examine ability UDCA protecting against chemotherapy‑associated mucositis. Sprague‑Dawley rats were randomly assigned five groups: Control, vehicle + 5‑fluorouracil (5‑FU),...
