BACKGROUND Several factors influence bowel preparation quality. Recent studies have indicated that the time interval between bowel preparation and the start of colonoscopy is also important in determining bowel preparation quality. OBJECTIVE To evaluate the influence of the preparation-to-colonoscopy (PC) interval (the interval of time between the last(More)
Behçet's disease is a chronic, relapsing, systemic inflammatory disease characterized by recurrent oral and genital ulcers, skin lesions, and ocular lesions. Gastrointestinal tract is occasionally involved in Behçet's disease, and the typical gastrointestinal lesions are punched-out, discrete mucosal ulcerations. Corticosteroids, 5-aminosalicylic acid(More)
BACKGROUND/AIMS The aims of this study were to compare the bowel-cleansing efficacy, patient affinity for the preparation solution, and mucosal injury between a split dose of polyethylene glycol (SD-PEG) and low-volume PEG plus ascorbic acid (LV-PEG+Asc) in outpatient scheduled colonoscopies. METHODS Of the 319 patients, 160 were enrolled for SDPEG, and(More)
BACKGROUND/AIMS Split-dose polyethylene glycol (PEG) is a standard bowel preparation regimen for colonoscopy, but the large volume is burdensome to ingest and the night dose causes sleep disturbance. This study was performed to evaluate the efficacy and tolerability of a bowel preparation protocol using low-volume morning-only PEG with specially designed(More)
BACKGROUND Hepatocellular carcinoma (HCC) screening has been recommended for hepatitis B virus (HBV)-infected individuals in an effort to detect HCC at a sufficiently early stage to provide potentially curative treatments. The study reported here is the first to address the rate of HCC screening use in an HBV endemic area. METHODS Data were collected from(More)
UNLABELLED The outcomes of patients with acute liver failure (ALF) vary greatly according to etiology. Emergency adult-to-adult living-donor liver transplantation (adult LDLT) would help address the shortage of available organs for patients with ALF, especially in hepatitis B virus (HBV)-endemic areas. We analyzed a prospective database of 110 consecutive(More)
BACKGROUND/AIMS Striking geographic differences have been noted in the etiology of fulminant hepatic failure (FHF). The prognosis of patients with FHF who do not receive liver transplantation in a timely manner is quite dismal. This study intended to identify the etiology and outcome of FHF in Korean adults and to examine the role of urgent living-donor(More)
BACKGROUND It is unclear to what extent insulin resistance (IR) modulates the association linking obesity to alanine aminotransferase (ALT) activity elevation. METHODS We measured the homeostatic model assessment for IR (HOMA-IR) in 1591 participants aged 12-18 years from the 2008 to 2009 Korea National Health and Nutrition Examination Survey. RESULTS(More)
BACKGROUND/AIMS In the present study, we evaluated the efficacy and tolerability between same-day bowel preparation protocols using 2 sachets of Picosulfate and a 4 L split-dose polyethylene glycol (PEG) bowel preparation for afternoon colonoscopy. METHODS The study had a single-center, prospective, randomized, and investigator-blinded, non-inferiority(More)
GOALS AND BACKGROUND Colonoscopy with consecutive esophagogastroduodenoscopy (CCEGD) can be more convenient than performing each procedure individually. There has been no randomized controlled trial comparing carbon dioxide (CO2) versus air insufflations during CCEGD in sedated patients. CO2 insufflation instead of air during CCEGD may reduce abdominal pain(More)
