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 No reported prospective, randomized study has evaluated the impact of an endoscopy nurse participating as a second observer during colonoscopy. OBJECTIVE To determine whether the participation of an endoscopy nurse enhanced the polyp detection rate (PDR) and adenoma detection rate (ADR) during screening colonoscopy. DESIGN Multicenter,(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)
Gastrointestinal leakage is one of the most serious post surgical complications and is a major source of mortality and morbidity. The insertion of a covered self-expandable metal stent could be a treatment option in selected cases. However, it is unclear how long the stent should be retained to achieve complete sealing, and membrane-covered stents have the(More)
Colorectal cancer is the second most common cancer in males and the fourth most common in females in Korea. Since the most of colorectal cancer occur through the prolonged transformation of adenomas into carcinomas, early detection and removal of colorectal adenomas are one of the most effective methods to prevent colorectal cancer. Considering the(More)
