Abstract: Aim: Intestinal metaplasia is the most common finding in routine endoscopic studies. The relationship between intestinal and dysbiosis leaking intestine now a known fact. In this study, we tried to show detection of chain events, which may cause many diseases, with zonulin stool, non-invasive method. Material Method: Endoscopy was performed on 20 patients dyspeptic complaints as Janua...
ABSTRACT Gastric cancer (GC) is one of the most common cancers in the world. Despite some improvement in the treatment of this type of cancer, the 5-year survival rate has been already remained low. Therefore further exploration of biological features and causes of gastric cancer is needed to reduce its occurrence. In sequential changes from superficial gastritis to dysplasia and cance...
Stomach cancer has an important place in medicine. Unfortunately, diagnosis of gastric is being established majority cases at the IV stage. So, yt necessary to detect tumors earliest stages carcinogenesis and evaluate treat precancerous diseases, such as atrophy intestinal metaplasia. Aims : To estimate value Narrow-band imaging Dual focus (NBI Focus) endoscopy capabilities differential metapla...
conclusions this study showed that the frequency of bilin was low among iranian patients with psc. high bilirubin and ca19-9 can be predictors of the development of bile duct epithelial changes in patients with psc. background primary sclerosing cholangitis (psc) as one of the most common chronic cholestatic liver diseases is a main predisposing factor for the development of cholangiocarcinoma ...
BACKGROUND Monoclonal precancerous cells undergo successive biochemical and genetic changes during the multistep process of carcinogenesis in the gastrointestinal tract. Despite a high association with intestinal-type stomach cancer (differentiated adenocarcinoma of the stomach), the role of intestinal metaplasia is unclear in stomach carcinogenesis. AIMS To study the clonality of intestinal ...
AIMS To clarify the relation between the serum titre of anti-Helicobacter pylori (H pylori) antibody and the extent of intestinal metaplasia of the gastric mucosa. METHODS The serum anti-H pylori IgG titres of 95 asymptomatic individuals (mean age 65 years) undergoing an annual health examination were measured and compared with the extent of intestinal metaplasia (absent, moderate, or extensi...
AIMS To investigate differences in expression of keratin 20, a cytoskeletal protein in gastrointestinal epithelial cells, in completely differentiated intestinal metaplasia (type I) and incomplete metaplasia (types II and III). METHODS Gastric biopsy specimens from 66 patients with intestinal metaplasia were analysed immunohistochemically. Expression of keratin 20 was quantified as the percen...
Columnar epithelium-lined oesophagus (CELO) is an acquired disorder associated with a high incidence of cancer. CELO consists of three histological types of epithelium: gastric-fundic, junctional, and specialised columnar, the last resembling intestinal metaplasia of the stomach. In a previous study of CELO an incompletely differentiated variant of intestinal metaplasia secreting sulphomucins (...
Approximately 23,000 new gastric cancer cases and 12,000 associated deaths occur annually in the United States. Intestinal metaplasia and gastric epithelial dysplasia are precursor lesions to gastric adenocarcinoma, but are not readily detectable clinically, radiographically, or endoscopically. A noninvasive method of precursor detection would require the ability to distinguish precursor lesion...
