BACKGROUND EUS response assessment in patients with locally advanced esophageal cancer undergoing neoadjuvant chemoradiation therapy (CRT) is limited by disintegration of the involved anatomic structures. OBJECTIVE Predictive and prognostic values of a prospectively defined maximum tumor thickness (MTT). DESIGN Prospective open-label phase ll study(More)
To explore the interactions between cholecystokinin (CCK) and the cholinergic system, we compared the effect of cholinergic or peptidergic CCK blockade on gallbladder contraction and pancreatic enzyme secretion using atropine and loxiglumide (a specific CCK antagonist) as pharmacological tools. Gallbladder contraction was measured by sonography and(More)
By means of loxiglumide, a potent and highly specific antagonist for cholecystokinin (CCK), the effects of blocking CCK receptors on gastrointestinal motility were investigated in a placebo-controlled study in healthy young men (aged 21-39, mean 24 years). Gallbladder contraction stimulated by ingestion of a liquid test meal was completely abolished by oral(More)
Twenty six patients with insulin dependent diabetes mellitus underwent a gastric emptying test, a gall bladder contraction test, an orocaecal transit study, and a colon transit test. Eleven patients had signs of cardiovascular autonomic neuropathy, 15 patients were without signs of cardiovascular autonomic neuropathy. Mean gastric clearance of radioopaque(More)
Gastrin-releasing peptide (GRP) was infused in graded doses (1-27 pmol/kg per h) to healthy human volunteers to study the effects on gastric, pancreatic and gallbladder functions as well as on gastrin, CCK and PP release. The results were compared to equimolar doses of synthetic bombesin. GRP significantly (P less than 0.05) stimulated gastric and(More)
Epidemiological studies using serological tests have shown that a large proportion of healthy people have antibodies against Helicobacter pylori (anti-Hp). It is uncertain whether the presence of anti-Hp indicates active infection or only past exposure to the micro-organism. In this study we determined anti-Hp with a specific enzyme linked immunosorbent(More)
Acute pancreatitis may be caused by a number of different drugs. However, reports on the frequency of drug-related acute pancreatitis and on the drugs involved are rare. We therefore investigated all cases of drug-related acute pancreatitis which had been reported to the Swiss Drug Monitoring Center (Schweizerische Arzneimittel-Nebenwirkungszentrale, SANZ)(More)
A 25-year-old male was hospitalized for diarrhea and weight loss. Since childhood he had experienced recurrent episodes of pneumonia and diarrhea. Physical and laboratory findings were compatible with malabsorption. On endoscopy, nodular lymphoid hyperplasia (NLH) of the small intestine was found. Common variable immunodeficiency syndrome (CVID) was(More)
Cholestasis is a frequent gastroenterological problem, which is tackled by endoscopic procedures. Little is known about bile viscosity, a major determinant of its flow. We measured the viscosity of bile from the common bile duct during endoscopic retrograde cholangiography. Bile was aspirated immediately after cannulation of the papilla and deep-frozen.(More)
