BACKGROUND/AIMS There have been few Asian studies regarding anxiety and depression associated with irritable bowel syndrome (IBS). The aim of this study was to evaluate the frequency and importance of anxiety and depression in Korean patients with IBS. METHODS A total of 124 IBS patients and 91 healthy subjects were enrolled consecutively. All(More)
BACKGROUND The accuracy of endoscopic ultrasonography (EUS) for preoperative staging of gastric cancer varies. The aim of this study was to investigate the accuracy of EUS tumor (T) and node (N) staging, and to identify the histopathological factors influencing accuracy based on the detailed tumor depth of gastric cancer. METHODS In total, 309 patients(More)
BACKGROUND/AIMS There are limited data regarding the clinical outcomes of self-expandable metal stents in the treatment of proximal colon obstruction. We compared the clinical outcomes of stent placement in patients with malignant proximal to distal colon obstructions. METHODS We reviewed medical records from 37 consecutive patients from three(More)
BACKGROUND/AIMS Our clinical experience and recent published literatures suggest that Clostridium difficile colitis (CDC) has become more common and potentially more pathogenic in recent years. The aim of study was to evaluate changes in the epidemiological features of CDC in hospitalized patients in Korea. METHODS We retrospectively reviewed all patients(More)
Whether addition of prokinetics to proton pump inhibitors improves esophageal peristalsis and symptoms in patients with gastroesophageal reflux disease (GERD) remains unknown. We evaluated the effect of mosapride, a 5-HT4 agonist, and PPI cotherapy in patients with GERD on esophageal motility using high-resolution manometry (HRM). This study was designed as(More)
Objectives. Sessile nonampullary duodenal tumors (SNADTs) are relatively rare and endoscopic resection of these lesions is considered more challenging than in other parts of the gastrointestinal tract. The aim of this study was to evaluate the feasibility of endoscopic resection for SNADT. Methods. Medical records including endoscopic resection for SNADT(More)
OBJECTIVES Data supporting the use of the proton pump inhibitor (PPI) test as a diagnostic test of gastroesophageal reflux disease (GERD) in Asia are lacking. The aims of this study were to evaluate the diagnostic characteristics of the PPI test and factors associated with responsiveness to PPIs. METHODS The PPI test was evaluated using lansoprazole (30(More)
BACKGROUND/AIMS Obesity is regarded as an important contributor to the increasing occurrence of gastroesophageal reflux disease. The aims of this study were to determine whether obesity is associated with gastroesophageal reflux in patients with gastroesophageal reflux disease and to identify the factors affecting increased acid exposure in obese patients.(More)
BACKGROUND/AIMS We assessed the bolus transit and motility characteristics in gastroesophageal reflux disease (GERD) patients with abnormal esophageal pH monitoring. METHODS We retrospectively reviewed the combined impedance-esophageal manometry data from consecutive patients who had abnormal acid exposure during 24-hour esophageal pH monitoring. We(More)
BACKGROUND/AIMS We evaluated the performance, clinical role, and diagnostic accuracy of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in gastrointestinal intramural lesions. METHODS Procedural and pathologic data were reviewed from consecutive patients undergoing EUS-FNA for intramural lesions. Final diagnoses were determined by surgical(More)
