INTRODUCTION Neo-angiogenesis, of great importance for tumour growth and nutrition, is preferentially mediated by the cytokine vascular endothelial growth factor (VEGF), which has a direct effect on vascular endothelial cell proliferation and migration. This study was designed to clarify whether VEGF is a suitable tumour marker in sera of patients with a(More)
The peritoneal lavage in peritonitis can be studied in a standardized manner only in animal models, because peritonitis is too variable and dependent on too many patient related factors. In this article answers are given to questions on the influence of different lavage substances on survival, local and systemic concentrations of bacteria, endotoxin, and(More)
The course in Gastrointestinal Surgery (GISC) aims at teaching and training resection, reconstruction and suture techniques of the upper gastrointestinal tract. Prior to, after and 5 years following the first course, participants were asked to answer a questionnaire requesting information regarding the adequacy of surgical training in their residency(More)
Per Simulation von Operationstechniken haben Weiterbildungskurse in der Viszeralchirurgie zum Ziel, Naht-, Resektions- und Rekonstruktionstechniken am Gastrointestinaltrakt zu vermitteln. Vor, nach und 5 Jahre nach erstmaligem Stattfinden des Weiterbildungskurses für gastrointestinale Chirurgie in Norderstedt wurde eine Befragung der Teilnehmer hinsichtlich(More)
Background and aims: Total mesorectal excision based operations is the gold standard of care in patients with middle and lower rectal cancer, but the extent of resection varies widely. In our view, extended lymphadenectomy is unnecessary with precise total mesorectal excision, i.e., anatomically correct and sharp surgery. Patients and methods: Sixteen(More)
Magnetic resonance imaging (MRI) was evaluated for its potential in assessment of acute pancreatitis compared to computed tomography (CT). 15 patients with acute pancreatitis were examined using a routine protocol including T1- and T2-weighted sequences and a fat-suppressed T1-weighted spin-echo sequence. Gadopentant-Dimeglumin (Gd-DTPA) was given. For(More)
INTRODUCTION The aim of our study was to investigate the influence of polypropylene meshes on the proliferation and apoptosis of human cell cultures in vitro. METHODS Human fibroblasts and HeLa cells were incubated in different densities (10(4), 3.10(4), 10(5) cells/well) together with polypropylene meshes (Prolene, 2 x 2 cm) in six-well culture dishes(More)
OBJECTIVES The time to positivity (TTP), measured as the time span between the start of incubation and the alert signal from the blood culture device, has been described as useful tool of prognosis in patients suffering from blood stream infection with Staphylococcus aureus, Escherichia coli and Klebsiella pneumonia. The present study investigates the(More)
INTRODUCTION We investigated the influence of resterilized polypropylen meshes (Prolene(R)) on proliferation and apoptosis of human fibroblasts in an experimental in vitro study. METHOD Human fibroblasts were seeded into six-well culture dishes in a density of 3 x 10 (4) cells/well. After resterilization of meshes (steam autoclave, 121 degrees C, 20 min.)(More)
BACKGROUND Blood stream infections (BSI) with Pseudomonas aeruginosa lead to poor clinical outcomes. The worldwide emergence and spread of metallo-β-lactamase (MBL) producing, often multidrug-resistant organisms may further aggravate this problem. Our study aimed to investigate the effect of MBL-producing P. aeruginosa (MBL-PA) and various other resistance(More)
