BACKGROUND AND STUDY AIMS The aim of this study was to compare prospectively the diagnostic efficacy of magnetic resonance (MR) imaging and endoscopic ultrasonography (EUS) in extrahepatic biliary obstruction. PATIENTS AND METHODS A total of 50 patients with suspected benign or malignant extrahepatic biliary obstruction underwent MR imaging, including MR(More)
UNLABELLED This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system 1 2 was adopted to define the strength of recommendations and the quality of evidence. MAIN RECOMMENDATIONS 1 ESGE recommends endoscopic en bloc resection for(More)
BACKGROUND AND AIMS Endoscopic resection is safe and effective to remove early neoplasia (ie,high-grade intra-epithelial neoplasia/early cancer) in Barrett's oesophagus. To prevent metachronous lesions during follow-up, the remaining Barrett's oesophagus can be removed by stepwise radical endoscopic resection (SRER). The aim was to evaluate the combined(More)
BACKGROUND Gastro-oesophageal reflux disease (GORD) is a frequently occurring disease that may be considered a public health issue, particularly in developed countries. The specificity of heartburn for the diagnosis of GORD is good. Our aim was to define the prevalence of heartburn in Belgium, characterizing both its impact on everyday life and the ensuing(More)
EDITOR—A g.133283G>A (nomenclature in accordance with Rowen et al) single base change in exon 3 of the cationic trypsinogen gene or T4, resulting in an Arg (CGC) to His (CAC) substitution at amino acid residue 122 (R122H, originally named R117H in the chymotrypsin numbering system; nomenclature discussed in detail in Chen and Ferec) of the cationic(More)
BACKGROUND Although colonoscopy is currently the optimal method for detecting colorectal polyps, some are missed. The Third Eye Retroscope provides an additional retrograde view that may detect polyps behind folds. OBJECTIVE To determine whether the addition of the Third Eye Retroscope to colonoscopy improves the adenoma detection rate. DESIGN(More)
Pancreaticopleural fistula secondary to chronic pancreatitis is a rare cause of recurrent pleural effusion. The demonstration of the fistula with endoscopic retrograde pancreatography and CT is invasive or limited. We report in two patients the use of magnetic resonance pancreatography as a noninvasive alternative to endoscopic retrograde pancreatography(More)
BACKGROUND AND STUDY AIMS The role of endoscopic submucosal dissection (ESD) in Barrett's neoplasia is ill-defined, although it might provide a higher curative resection rate and better histologic assessment than endoscopic mucosal resection (EMR). We aimed to assess efficacy, safety, and long-term results of ESD. PATIENTS AND METHODS A retrospective(More)
With the increasing use of antiplatelet agents (APA), their management during the periendoscopic period has become a more common and more difficult problem. The increase in use is due to the availability of new drugs and the widespread use of drug-eluting coronary stents. Acute coronary syndromes can occur when APA therapy is withheld for noncardiovascular(More)
Several missense mutations, including R122H, N29I, K23R, A16V and D22G, in the cationic trypsinogen gene (PRSS1), have been associated with certain forms of hereditary pancreatitis (HP). Their occurrence in the idiopathic chronic pancreatitis (ICP) and whether novel mutations could be identified in PRSS1 remain to be further evaluated. These were addressed(More)
