BACKGROUND Covered biliary metal stents have been developed to prevent tumor ingrowth. Previous comparative studies are limited and often include few patients. OBJECTIVE To compare differences in stent patency, patient survival, and complication rates between covered and uncovered nitinol stents in patients with malignant biliary obstruction. DESIGN(More)
BACKGROUND AND STUDY AIM Small-bowel tumors account for 1% - 3% of all gastrointestinal neoplasms. Recent studies with video capsule endoscopy (VCE) suggest that the frequency of these tumors may be substantially higher than previously reported. The aim of the study was to evaluate the frequency, clinical presentation, diagnostic/therapeutic work-up, and(More)
BACKGROUND Flat and depressed colorectal tumours are common in Japan but are very rare or non-existent in Western countries. AIMS To study the occurrence of flat colorectal tumours in a southern Swedish population. METHODS In this prospective study, 371 consecutive European patients were examined by high resolution video colonoscopy combined with(More)
BACKGROUND Colon capsule endoscopy (CCE) represents a noninvasive technology that allows visualization of the colon without requiring sedation and air insufflation. A second-generation colon capsule endoscopy system (PillCam Colon 2) (CCE-2) was developed to increase sensitivity for colorectal polyp detection compared with the first-generation system. (More)
BACKGROUND Adequate bowel preparation prior to colonic diagnostic procedures is essential to ensure adequate visualisation. SCOPE This consensus aims to provide guidance as to the appropriate use of bowel preparation for a range of defined clinical circumstances. A consensus group from across Europe was convened and met to discuss appropriate bowel(More)
BACKGROUND Markedly decreased or absent gastric acid production is associated with a number of clinically significant conditions, and identification of patients with hypo/achlorhydria may be important. However, current methods of assessing impaired acid secretion are unreliable, time-consuming, and/or complex. The aim of this prospective study was to(More)
BACKGROUND & AIMS The selective cyclooxygenase-2 inhibitor lumiracoxib has been shown to reduce endoscopically detected ulcers and ulcer complications in the upper gastrointestinal tract compared with nonselective nonsteroidal anti-inflammatory drugs. We investigated whether lumiracoxib would reduce small-bowel injury compared with naproxen plus omeprazole.(More)
PillCam colon capsule endoscopy (CCE) is an innovative noninvasive, and painless ingestible capsule technique that allows exploration of the colon without the need for sedation and gas insufflation. Although it is already available in European and other countries, the clinical indications for CCE as well as the reporting and work-up of detected findings(More)
BACKGROUND Symptomatic response to acid inhibition can be used as a guide in diagnosing patients with reflux symptoms. The proton-pump inhibitor (PPI) omeprazole has been used as such a diagnostic tool. Intragastric acid control with esomeprazole is more effective than other PPIs and has the potential to offer an advance in the diagnostic use of PPIs. (More)
BACKGROUND Three different classification systems for the evaluation of Barrett's esophagus (BE) using magnification endoscopy (ME) and narrow-band imaging (NBI) have been proposed. Until now, no comparative and external evaluation of these systems in a clinical-like situation has been performed. OBJECTIVE To compare and validate these 3 classification(More)
