In this randomized controlled multicenter trial, we compared endoscopic variceal banding ligation (VBL) with propranolol (PPL) for primary prophylaxis of variceal bleeding. One hundred fifty-two cirrhotic patients with 2 or more esophageal varices (diameter >5 mm) without prior bleeding were randomized to VBL (n = 75) or PPL (n = 77). The groups were well(More)
Long-term results after liver resection for hilar cholangiocarcinoma are still not satisfactory. Previously, we described a survival advantage of patients who undergo combined right trisectionectomy and portal vein resection, a procedure termed “hilar en bloc resection.” The present study was conducted to analyze its oncological effectiveness compared to(More)
Esophageal perforations remain a life-threatening event requiring rapid diagnosis and treatment. Surgical repair and interventional endoscopic or conservative treatment are the common treatment methods. From 1998 to 2006, the authors retrospectively analyzed 62 patients treated for esophageal perforation. Data were evaluated for cause of perforation,(More)
Carbapenemase-producing Enterobacteriaceae (CPE) have become a major problem for healthcare systems worldwide. While the first reports from European hospitals described the introduction of CPE from endemic countries, there is now a growing number of reports describing outbreaks of CPE in European hospitals. Here we report an outbreak of Carbapenem-resistant(More)
BACKGROUND Advanced and incurable Klatskin tumors of Bismuth-type III and IV cause obstructive jaundice. Palliation of patients with Klatskin tumors is usually carried out by bilateral endoscopic stent placement. Endoscopic retrograde cholangiography (ERC) in such patients is associated with a comparatively high morbidity and mortality mainly due to(More)
BACKGROUND AND AIMS Colonoscopy is an established method of colorectal cancer screening, but has an adenoma miss rate of 10-20%. Detection rates are expected to improve with optimised visualisation methods. This prospective randomised study evaluated narrow-band imaging (NBI), a new technique that may enhance image contrast in colon adenoma detection. (More)
HISTORY A 53-year-old man with long-standing Crohn's disease presented with recurrent abdominal pain and vomiting; lipase levels were elevated. INVESTIGATIONS AND DIAGNOSIS At admission ultrasound demonstrated a swollen head of the pancreas, dilated pancreatic and intrahepatic bile ducts and peripancreatic fluid. At upper gastrointestinal endoscopy a 10(More)
Due to a vulnerable blood supply of the bile ducts, biliary complications are a major source of morbidity after liver transplantation (LT). Manifestation is either seen at the anastomotic region or at multiple locations of the donor biliary system, termed as nonanastomotic biliary strictures. Major risk factors include old donor age, marginal grafts and(More)
BACKGROUND & AIMS IgG4-related cholangitis is a chronic inflammatory biliary disease that involves different parts of the pancreatobiliary system, but little is known about its mechanisms of pathogenesis. A T-helper (Th) 2 cell cytokine profile predominates in liver tissues from these patients. We investigated whether Th2 cytokines disrupt the barrier(More)
OBJECTIVES Endoscopic ultrasonography (EUS) with the adjunct of EUS-guided fine needle aspiration has become an important diagnostic modality in gastroenterologic oncology. EUS-guided fine needle aspiration mainly relies on cytology; data are scarce that compare cytology and histology. While testing a 22-gauge prototype needle, we prospectively compared the(More)
