Background. There is a lack of prospective studies evaluating the natural history colonic ischaemia (CI). We performed such study to evaluate clinical presentation, outcome, and mortality as well variables associated with poor prognosis. Methods. An open, prospective, multicentre was conducted in 24 Spanish hospitals serving population 3.5 million people. The included only patients who met criteria for definitive or probable CI. A website (www.colitisisquemica.org) provided logistical...
Summary Aim : To compare the efficacy of esomeprazole, 20 mg once daily, vs. lansoprazole, 15 for maintenance treatment patients with healed reflux oesophagitis. Methods During initial open healing phase, 1391 endoscopically verified oesophagitis and a history heartburn, or without acid regurgitation, received esomeprazole 40 4–8 weeks. Patients who were (identified by endoscopy at 4 8 weeks) symptom free then randomized to receive 6 months daily. Results Esomeprazole, maintained...
To date, ERCP has been the reference technique in diagnosis of pancreatic duct pathology. The aim present study was to evaluate accuracy magnetic resonance cholangiopancreatography (MRCP), a relatively new, noninvasive diagnostic method, studying duct.A prospective 15-month done 78 patients with suspected biliopancreatic pathology and indications for ERCP. In all cases, MRCP performed <72 h before Both techniques were used assess size tract (normal or dilated), presence absence obstruction,...
Abstract Postoperative biliary tract lesions are becoming increasingly common. The diagnosis is made by direct cholangiography via endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic (PTC). present comparative study evaluates the diagnostic efficacy of magnetic resonance (MRCP) in application to iatrogenic bile duct injury. A prospective blind was performed, contrasting MRCP and ERCP 10 patients with suspected postoperative lesions. performed less than 72 h...
Within a nowadays context characterised by an increasing number of television channels and widely fragmentation the audience, study content from consumer's perspective acquires special interest for managers stations. This paper, given aforementioned reality, analyses identifies relationship structure that underlies constructs satisfaction quality in order to gain more in-depth understanding behaviour consumers. The methodology applied is structural equation models results clearly show causal...
Ultrasonography (US) is currently the reference technique for evaluating gallbladder pathology. The aim of this study was to prospectively determine diagnostic efficacy magnetic resonance cholangiography (MRCP) in gallbladder, as compared with US. included 80 patients (mean age, 69.3 years; male-to-female ration, 1.3:1) who underwent prospective US and MRCP; 5 whom MRCP contraindicated were excluded. In all cases, performed before MRCP. Ultrasound sensitivity specificity. Magnetic...
Introduction : Esomeprazole, the first proton pump inhibitor to be developed as an optical isomer, has demonstrated more effective healing vs. omeprazole and lansoprazole in patients with reflux oesophagitis (RO). However, RO recurs a high proportion (∼80%) of these within 12 months initial therapy, highlighting importance maintenance treatment. Previous studies have shown esomeprazole therapy healed patients. Aim: This study was conducted compare 20 mg once daily (o.d.) 15 o.d. for...
