Human intestinal microbiota create a complex polymicrobial ecology. This is characterised by its high population density, wide diversity and complexity of interaction. Any dysbalance of this complex intestinal microbiome, both qualitative and quantitative, might have serious health consequence for a macro-organism, including small intestinal bacterial(More)
BACKGROUND Colonic mucosal abnormalities associated with sodium phosphate colonic preparations have been described. The aim of this prospective study was to determine the frequency at which these occur and to define the endoscopic and histopathologic patterns of these changes. METHODS Within a 16-month period, 730 of patients referred for elective(More)
The paper provides a basic review of intestinal microflora and its importance in liver diseases. The intestinal microflora has many important functions, above all to maintain the microbial barrier against established as well as potential pathogens. Furthermore, it influences the motility and perfusion of the intestinal wall, stimulates the intestinal immune(More)
Biodegradable stents, which are made of various synthetic polymers, such as polylactide or polyglycolide, or co-polymers, such as polydioxanone, can be used for the treatment of benign refractory stenoses of the gastrointestinal tract. Here we report 11 patients (median age 41) with stenosing Crohn's disease of the small and/or large intestine. Endoscopic(More)
BACKGROUND We hypothesised that different solutions for submucosal injection may influence early healing of endoscopic mucosal resection (EMR). The aim of this study was to evaluate histological and immunological changes after EMR in experimental pigs. MATERIALS AND METHODS Two parallel EMRs on the anterior and posterior wall of the gastric body were(More)
BACKGROUND Double-balloon enterocopy (DBE) is still under evaluation, including its yield and safety aspects. OBJECTIVE Our purpose was to consider the relationship between DBE and hyperamylasemia. DESIGN Single-center prospective study. SETTING Tertiary referral hospital, conducted from March to October 2006. PATIENTS Thirty-five oral DBEs were(More)
Helicobacter pylori (Hp) is the most common chronic bacterial infection in humans worldwide. The prevalence of Hp infection is high in developing countries (80-90%) and lower in developed countries (10-30%). In vast majority of infected individuals, the infection is acquired early in life. The risk of Hp infection is related to low socio-economic status and(More)
Peutz-Jeghers syndrome (PJS) is an inherited, autosomal dominant disorder distinguished by hamartomatous polyps in the gastrointestinal tract and pigmented mucocutaneous lesions. Prevalence of PJS is estimated from 1 in 8300 to 1 in 280,000 individuals. PJS predisposes sufferers to various malignancies (gastrointestinal, pancreatic, lung, breast, uterine,(More)
Double-balloon enteroscopy (DBE) is a new technique, firstly published in 2001 by Yamamoto, inventor of this unexceptionable method. DBE allows complete visualisation, biopsy, and treatment in the small bowel. The procedure is safe and useful. The DBE has a potential to be a standard of enteroscopy by replacing conventional push enteroscopy. DBE together(More)
BACKGROUND Platelets are involved in the pathogenesis of chronic inflammation. Thrombocyte count and platelet volume are considered as a useful activity marker of inflammatory bowel disease. The aim of the study was to compare the yield of mean platelet volume with clinical and other laboratory markers of activity in Crohn's disease (CD). METHODS AND(More)
