INTRODUCTION Cholecystokinin (CCK) belongs to a group of endogenous molecules known as brain-gut neuropeptides and functions as a neuropeptide as well as a gut hormone. It remains unclear whether genetic variation of the CCK receptor plays a role in irritable bowel syndrome (IBS). The aim of this study was to determine and compare the allele and genotype(More)
BACKGROUND/AIMS Colon transit time (CTT) is a useful diagnostic tool in chronic constipation, but requires good patient compliance. We analyzed the correlation between the gas volume score (GVS) and CTT in patients with chronic constipation. METHODS The study included 145 consecutive patients (65 men) with chronic constipation. The primary outcome was the(More)
BACKGROUND/AIMS Synchronous/metachronous gastric epithelial neoplasias (GENs) in the remaining lesion can develop at sites other than the site of endoscopic resection. In the present study, we aimed to investigate the predictive value of serum pepsinogen for detecting multiple GENs in patients who underwent endoscopic resection. METHODS In total, 228(More)
BACKGROUND/AIMS Gastroesophageal reflux (GER) has been implicated in the pathogenesis of chronic cough. The aims of this study were to evaluate the diagnostic usefulness of multichannel intraluminal impedance combined with pH monitoring (MII/pH monitoring) in patients with suspected symptoms of gastroesophageal reflux disease (GERD) and to assess the(More)
BACKGROUND/AIMS Percutaneous coronary intervention (PCI) is often performed therapeutically, and antithrombotic treatment is required for at least 12 months after stent implantation. However, the development of post-PCI upper gastrointestinal bleeding (UGIB) increases morbidity and mortality. We investigated the incidence and risk factors for UGIB in Korean(More)
Functional dyspepsia (FD) is a highly prevalent disorder, characterized by persistent or recurrent pain or discomfort centered in the upper abdomen without evidence of organic that might explain the symptoms. Several factors have been proposed to play a role: delayed gastric emptying, Helicobacter pylori infection, hypersensitivity to gastric distension,(More)
BACKGROUND/AIMS Intraductal ultrasonography (IDUS) has been performed as an adjunct to endoscopic retrograde cholangiography (ERC) during radiocontrast cholangiography (RC). Radiation exposure during RC poses a health risk to both patients and examiners. We evaluated the feasibility of IDUS without RC in various extrahepatic biliary diseases. METHODS IDUS(More)
Intraductal ultrasonography (IDUS) is one of the most useful diagnostic tools for various extrahepatic biliary diseases. However, conventional IDUS has some limitations in providing accurate cross-sectional imaging of the bile duct in patients with extensive pneumobilia. Using a balloon-sheathed catheter, the US system (balloon-sheathed IDUS) can overcome(More)
BACKGROUND/AIMS Endoscopic retrograde cholangiopancreatography (ERCP) is technically challenging in patients with altered gastrointestinal (GI) anatomy. We evaluated the feasibility of cap-assisted ERCP in patients with altered GI anatomy. METHODS The outcome of ERCP procedures (n=136) was analyzed in 78 patients with Billroth II (B-II) gastrectomy(More)
