BACKGROUND The differential diagnosis of biliary strictures remains a challenge. This study evaluated magnetic resonance cholangiopancreatography (MRCP) as a new procedure in comparison with the established methods of diagnosis including ERCP or percutaneous transhepatic cholangiography (PTC), CT, and EUS. METHODS Fifty patients (21 men, 29 women, mean(More)
Terminology in classification of pancreatograms was discussed at a recent international workshop on chronic pancreatitis. A new terminology based on morphological radiographic appearances and a new classification to describe the severity and localisation of pancreatogram changes were agreed. Pancreatograms in chronic pancreatitis are graded as normal or(More)
In a prospective study, endoscopic ultrasonography was compared with transabdominal ultrasonography, computed tomography, and angiography in 60 consecutive patients with pancreatic (n = 46) and ampullary (n = 14) cancer considered to be candidates for surgery. The diagnostic value of these imaging procedures in determining local resectability was assessed.(More)
In a prospective study from 1988 to 1990, 132 patients with suspected pancreatic tumor were examined with endoscopic ultrasound (EUS), transabdominal ultrasound (US), computed tomography (CT), and ERCP. The final diagnosis of 102 pancreatic tumors of different origin (76 malignant and 26 inflammatory tumors) and the exclusion of a pancreatic tumor in 30(More)
BACKGROUND AND STUDY AIMS In patients with achalasia, intrasphincteric injection of botulinum toxin (BTX) has been suggested as an alternative regimen to balloon dilation and has been shown to be superior to placebo injection. The aim of the present study was to test the effectiveness, the long-term outcome and the cumulative costs of BTX injection in(More)
Infection with Helicobacter pylori is associated with different human gastric diseases. Biochemical studies, in vitro adherence assays, and in vivo animal models revealed that epithelial attachment of H. pylori can be mediated by the blood-group antigen-binding adhesin (BabA) targeting human Lewis(b) surface epitopes. Studies with transgenic mice expressing(More)
BACKGROUND AND AIMS After an initial period of excellent results with newly introduced imaging procedures, the accuracy of most imaging methods declines in later publications. This effect may be due to various methodological factors involved in the research. Using the example of endoscopic ultrasound (EUS), this study aimed to elucidate one of the factors(More)
Gastroesophageal reflux disease (GERD) and the complications associated with it are very common in the Western world. There has been speculation for many years that certain dietary and lifestyle factors may play a role in the pathogenesis or course of GERD. However, a wide-ranging review of the available data reveals conflicting findings regarding the(More)
BACKGROUND Endoscopic treatment modalities are well established for the removal of bile duct stones. For the small percentage of stones that are difficult or impossible to extract by conventional means, more sophisticated endoscopic techniques or associated modalities such as intracorporeal laser lithotripsy (ILL) and extracorporeal shock wave lithotripsy(More)
BACKGROUND The incidence of distal oesophageal adenocarcinoma is rising, with chronic reflux and Barrett's oesophagus being considered risk factors. Reliable detection of Barrett's oesophagus during upper endoscopy is therefore mandatory but requires both endoscopy and histology for confirmation. Appropriate management of patients with endoscopic suspicion(More)
