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 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 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)
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)
BACKGROUND/AIMS Available data about reflux patterns and symptom determinants in the gastroesophageal reflux disease (GERD) subtypes off proton pump inhibitor (PPI) therapy are lacking. We aimed to evaluate reflux patterns and determinants of symptom perception in patients with GERD off PPI therapy by impedance-pH monitoring. METHODS We retrospectively(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)
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)
