BACKGROUND/AIMS Endoscopic resection has proven to be a safe and effective alternative to surgery for duodenal adenomas. However, few data are available on the adequacy of resection and long-term outcomes. This study evaluated the efficacy and longterm endoscopic findings in a cohort of Korean patients who underwent endoscopic mucosal resection (EMR) of(More)
Although the incidence of perforation after endoscopic procedures of the colon is low, the rising number of diagnostic colonoscopies could pose relevant health problems. Optimizing treatment may reduce the probability of severe complications. This study aimed to determine perforation frequency and the management of perforations that occurred during(More)
BACKGROUND The optimal technique for removal of diminutive or small colorectal polyps is debatable. OBJECTIVE To compare the complete resection rates of cold snare polypectomy (CSP) and cold forceps polypectomy (CFP) for the removal of adenomatous polyps ≤7 mm. DESIGN Prospective randomized controlled study. SETTING A university hospital. PATIENTS A(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 In patients with acute nonvariceal upper gastrointestinal bleeding, rebleeding after an initial treatment is observed in 10-20% and is associated with mortality. AIM To investigate whether the initial serum C-reactive protein level could predict the risk of rebleeding in patients with acute nonvariceal upper gastrointestinal bleeding. METHODS(More)
Capsule endoscopy (CE) has proven to be highly effective at detecting small bowel lesions, but studies regarding the diagnostic impact of CE on ileitis are rare. We evaluated the diagnostic value of small bowel CE for isolated ileitis observed during ileocolonoscopy. The CE results in 137 patients initially diagnosed with ileitis without colonic mucosal(More)
BACKGROUND/AIMS Long-term use of proton pump inhibitor (PPI) induces hypergastrinemia, which results from the suppression of gastric acid secretion. Hypergastrinemia causes enterochromaffin-like (ECL) cell hyperplasia, which is a predisposing factor of carcinoid tumor of stomach. The aim of this study was to identify the effect of long-term gastric acid(More)
Myxedema ascites caused by hypothyroidism is rare, so its diagnosis is often delayed and patients frequently receive unnecessary procedures such as liver biopsies and exploratory laparotomies. We report a 71-yr-old man with clinical ascites that was the first manifestation of hypothyroidism, and which resolved completely in response to thyroid hormone(More)
BACKGROUND/AIMS Alterations of the expression pattern of mucins and trefoil peptides have been described in gastric adenocarcinomas and in their precursor lesions. The aim of this study was to determine the progression patterns of intestinal metaplasia (IM) subtypes by analyzing the expression patterns of TFF1 and MUC5AC in different subtypes of IM of the(More)
