BACKGROUND/AIMS Two-liter polyethylene glycol (PEG) is the most commonly used bowel-cleansing regimen in Taiwan, but its efficacy is unsatisfactory. The aim of this study was to compare 2-liter and 3-liter PEG in terms of their impact on colonoscopy quality among an average-risk population. METHODS Two-liter PEG was provided between August 2012 and May(More)
BACKGROUND Combination therapy with pegylated interferon (pegIFN)-α and ribavirin (RBV) for chronic hepatitis C virus (HCV) infection is associated with reduction in hemoglobin (Hb) concentrations and anemia. The aim of this study was to evaluate the magnitude and frequency of change in Hb and determine the predictive risk factors for Hb decrease during(More)
GOAL To examine the residual gastric volume (RGV) in colonoscopy after bowel preparations with 3-L polyethylene glycol (PEG). BACKGROUND Obstacles to high-volume bowel preparation by anesthesia providers resulting from concerns over aspiration risk are common during colonoscopy. STUDY Prospective measurements of RGV were performed in patients undergoing(More)
AIM To compare the diagnostic yield of heterotopic gastric mucosa (HGM) in the cervical esophagus with conventional imaging (CI) and narrow-band imaging (NBI). METHODS A prospective study with a total of 760 patients receiving a CI examination (mean age 51.6 years; 47.8% male) and 760 patients undergoing NBI examination (mean age 51.2 years; 45.9% male).(More)
BACKGROUND/AIMS Same-day bidirectional endoscopy (BDE) is a commonly performed procedure, but the optimal sequence of the procedure with carbon dioxide insufflation is not well established. In this study, we investigated the optimal sequence for same-day BDE without polypectomy under moderate sedation and carbon dioxide insufflation in terms of sedation(More)
A 3-l polyethylene glycol (PEG) solution provided better bowel cleansing quality than a 2-l solution for outpatient colonoscopy. Predictors of suboptimal preparation using a 3-l PEG have not been previously reported. To investigate the possible predictors of suboptimal bowel preparation using 3-l of PEG. We analyzed a database of 1404 consecutive(More)
BACKGROUND AND AIM Same-day bidirectional endoscopy (BDE) is a commonly performed procedure, but the optimal sequence for the procedure with moderate conscious sedation is not well-established. We investigated the optimal sequence for same-day BDE under moderate conscious sedation and carbon dioxide insufflation in terms of sedation doses, patient(More)
