Background And Aims: There are discrepancies in the classification of early carcinoma in colorectal neoplasia between Japanese and Western criteria. However, no studies have investigated the clinicopathological risk factors associated with early carcinoma according to these criteria.
Methodology: We compared the clinicopathological risk factors of early carcinoma with those of dysplasia, and used multivariate analysis to elucidate the independent risk factors associated with early carcinoma.
Association of hyper-LDL cholesterolemia with increased risk of colorectal adenoma.

Background/aims: Previous studies on the association between dyslipidemia and the presence of colorectal adenoma showed conflicting results, and were limited due to small sample sizes, inconsistent definitions of dyslipidemia, or a lack of data on full lipid profiles. The aim of this study was to determine the association between colorectal adenomas and dyslipidemia according to the definition by the National Cholesterol Education Program- Adult Treatment Panel III.
Methodology: We conducted a retrospective, cross-sectional study in subjects who underwent screening colonoscopy and blood tests for full lipid profiles.
Background/aims: Gallbladder polyps and colorectal adenomas share many common risk factors; however, their association has never been studied. The aim of this study was to investigate this association in asymptomatic healthy subjects.
Methods: Consecutive asymptomatic subjects who underwent both screening colonoscopy and abdominal ultrasonography at Kyung Hee University Hospital in Gang Dong between July 2010 and April 2011 were prospectively enrolled.
Aim: To investigate whether patients with obstructive sleep apnea (OSA) are at risk of sedation-related complications during diagnostic esophagogastroduodenoscopy (EGD).
Methods: A prospective study was performed in consecutive patients with OSA, who were confirmed with full-night polysomnography between July 2010 and April 2011. The occurrence of cardiopulmonary complications related to sedation during diagnostic EGD was compared between OSA and control groups.
Background: The advantage of the quantitative fecal immunochemical test (FIT) is the flexibility to set the positivity threshold. However, the diagnostic success of the FIT has not been compared for standard and low cut-off thresholds.
Aims: The purpose of this study was to compare the diagnostic success of FIT for standard and low cut-off thresholds.
Background: Type 2 diabetes mellitus is associated with an increased risk of colorectal neoplasia. However, association between prediabetes and colorectal adenoma has not been reported.
Aims: The aim of this study was to evaluate the relationship between prediabetes and the presence of colorectal adenomas.
Background/aims: Fecal immunochemical test (FIT) is an integral component of most colorectal cancer (CRC) screening programs. However, little is known about clinical risk factors associated with advanced colorectal neoplasia (CRN) despite negative FIT results. The aim of this study was to determine the clinical predictors of advanced CRN despite negative FIT results.

Aims: The aim of this study was to determine whether a high ambient temperature on the day of screening may decrease the performance of FITs in population-based screening.
Methods: We performed FITs for asymptomatic participants aged 50 years or older.
