PURPOSE To assess the utility of dynamic MR pancreatography in the evaluation of the behavior of the pancreatic duct after secretin stimulation and to estimate pancreatic exocrine reserve in patients suspected of having acute recurrent or chronic pancreatitis. MATERIALS AND METHODS Ten healthy volunteers and 13 patients suspected of having pancreatic(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)
PURPOSE An outbreak of gram-negative bacteremia in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) was investigated to determine the sources of infection and to control transmission. PATIENTS, METHODS, AND RESULTS The incidence of post-ERCP bacteremia increased from 1.6% (60 of 3,696) procedures to 3.6% (53 of 1,454) procedures(More)
PURPOSE To compare duodenal filling seen at magnetic resonance (MR) pancreatography after secretin stimulation and biochemical parameters determined with the intraductal secretin test (IDST) for evaluation of pancreatic exocrine function. MATERIALS AND METHODS MR pancreatography after secretin stimulation and IDST were performed in 41 patients with(More)
BACKGROUND AND STUDY AIMS Endoscopic therapy of high-grade dysplasia (HGD) and superficial adenocarcinoma associated with Barrett's esophagus (BE), using Nd:YAG laser, KTP laser, or photodynamic therapy (PDT), has been reported to be effective in a curative role. Argon plasma coagulation (APC) appears to be effective in the eradication of nondysplastic(More)
BACKGROUND The clinical significance of pancreas divisum (PD) remains controversial. Secretin-enhanced magnetic resonance cholangiopancreatography (S-MRCP) is a noninvasive diagnostic procedure that relies on the dynamic response of the main pancreatic duct (MPD) to secretin stimulation. The aim of this study was to determine the frequency of PD and to(More)
BACKGROUND Reoperations for complications of bariatric surgery are associated with high morbidity and mortality. It is not known whether endoscopic treatment may reduce reoperation rates. METHODS Twenty-one patients underwent endoscopic treatment for persisting large anastomotic leaks before considering redo surgery. Eight patients had a gastric bypass,(More)
BACKGROUND Endoscopic treatment of postoperative benign bile duct strictures (BBDS) is technically challenging, and the long-term outcome after stricture dilation remains poorly defined. METHODS Forty-eight cases of postoperative BBDS with attempted endoscopic treatment (either transient plastic stenting or definitive metal stent insertion) were reviewed.(More)
Between January 1985 and September 1989, 75 patients presenting with severe chronic pancreatitis with distal stricture and upstream dilatation underwent stenting of the main pancreatic duct (MPD) through the major papilla (n = 54) or minor papilla (n = 21) in order to drain the predominant duct through a 10 F plastic prosthesis. All patients had undergone(More)
BACKGROUND Intestinal metaplastic mucosa in Barrett's oesophagus can be replaced by squamous epithelium after mucosal thermal ablation associated with acid suppression therapy. AIMS To assess whether restoration of squamous epithelium can be obtained after ablation of Barrett's oesophagus using argon plasma coagulation (APC) associated with proton pump(More)
