The Purpose of the Study: Determine the pathogenetic significance of express molecules PCNA, Bcl-2, NF-Kb and tachykinins (substance P, neurokinin A) in patients with gastroesophageal reflux disease (GERD), receiving polychemotherapy (PCT)., Materials and Methods: In total 60 patients were examined with GERD time-divided into 2 equal groups on the receiving PCT Leukemia over standard dose for at least one year. The first group consisted of 30 subjects with non-erosive GERD (NEGERD) endoscopically positive form receiving PCT. The second group consisted of 30 subjects with erosive form of GERD (EFGERD) receiving PCT. Patients underwent endoscopy, morphological and immunohistochemical examination of the esophageal mucosa to the definition expression of molecules PCNA, Bcl-2, neurokinin A, substance P and factor Nf-Kb. In patients with refractory form of GERD to proton pump inhibitors therapy (PPIs), additionally imposed ursodeoxycholic acid., The Results: Patients with NEGERD receiving PCT in 33.3% of cases formed refractory to PPIs form of the disease, when EFGERD refractoriness occurs in 46.7% of patients, which is associated with slowing the proliferation of epithelial cells of the esophagus due to decreased expression of PCNA. Reduced expression of neurokinin A in patients receiving PCT is associated with less activity and intensity of inflammation of esophageal mucosa. Against the background of a high degree of PCT expression of Bcl-2 and factor Nf-Kb, which may explain the frequent detection of atrophic and meta- plastic changes in the esophageal mucosa. Appointment of ursodeoxycholic acid in the complex therapy of GERD can overcome resistance to PPIs and improve the performance of cell renewal., Conclusion: Due to the frequent development of GERD refractory to PPIs in patients suffering from diseases requiring the appointment of long-term courses of PCT requires the appointment of cytoprotective therapy, as that can be used ursodeoxycholic acid.

Aim: To investigate the phenotypic and visceral signs of connective tissue dysplasia (CTD) and comorbid diseases of the digestive system in gastroesophageal reflux disease (GERD) patients with different types of esophageal reflux as the predictors of its variants., Material and Methods: In 124 patients with GERD the clinical features, phenotypic and visceral signs of undifferentiated CTD were studied in details., Results: In 82.0% of patients with GERD associated with gastroesophageal type of reflux (GER) phenotypic and especially visceral signs of STD were detected, mainly in the form of cardiochalasia and hiatal hernia. In patients with duodenogastroesophageal reflux symptoms (DGER) the signs of STD were marked in 42.0% of cases, mostly in the form of biliary tract structure abnormalities. The risk of GERD associated with prevalence of GER, was 11.9 times higher in the presence of diagnostically meaningful combination of 6 or more signs of STD than in patients with DGER. Realization of predictor options in GER occurs in the preference of sharp, acidic foods, spices, taking medications that reduce lower esophageal sphincter tone. GERD, associated with DGER, is formed in patients with family history of diseases of the biliary tract and in the preference of food rich of calories., Conclusion: Study of STD symptoms as predictors of structural development of GERD and its variants is prospective to predict disease, choice of profession and eating behavior, primarily in young adults.

Aim: To determine the chronic cholangitis risk factors and to provide a practically significant diagnostic criteria of chronic cholangitis in patients after cholecystectomy., Materials and Methods: Were examined the clinical, anamnestic data, clinical laboratory and instrumental studies of the condition of the hepatobiliary system in 127 patients with chronic cholangitis after cholecystectomy. The determination of microbial contamination of bile was performed during the duodenal intubation., Results: In the bile microbial landscape study were noted the violation of biliary system microbiota in 92.1% of cases. Herewith identified a combination of bacterial factors with parasitic invasion (mixed infection) in 28 (22.0%) patients. Cholangitis develops in the presence of duodeno biliary reflux, duodenal motility disorders and hypotonia of Oddi's sphincter in the early postoperative period. In the late periods after cholecystectomy, cholangitis chronization defines outflow obstruction and cholestasis due to functional or organic causes in most patients., Conclusions: Risk factors for chronic cholangitis should be referred to long history of gallstone disease, performance of cholecystectomy in the emergency order against the inflammatory process of thehepatobiliary system, absence of adequate correction of postoperative hypertension of bile duct, destruction of sphincter apparatus major duodenal papilla during surgery.

The article presents research data of duodenogastral reflux (DGR) role in patients with gastroesophageal reflux disease. It is shown that in the presence DGR, the reflux esophagitis is detected at a higher frequency and outside of esophageal manifestations of the disease. The comorbidities of hepatobiliary zone and pancreas contributes to the DGR development, as well as the syndrome of bacterial overgrowth in the small intestine.

Endoscopical and histological features of oesophagogastroduodenal zone, parameters of pH-metry and electrogastroenterography, qualitative and quantitative characteristics of microbiocenosis were studied in 80 female persons with postcholecystectomy syndrome more then a year after cholecystectomy. In the presence of duodenogastral reflux the most natural is the combination of distal oesophagitis, antral atrophic gastritis and duodenitis, accompanied with low level of gastric acidity, gastric hypokinesis and duodenal dyskinesis, dysbacteriosis of mucosal microflora with its quantitative increase and appearance of bacteria with expressed pathogenicity non-typical for this biotope. These data should be taken into consideration for determination of pre- and postoperative treatment tactics for patients with gallstones.

Objective: To determine the frequency of duodenogastric reflux (DGR), and to assess the changes in the gastric mucosa in the presence of bile reflux., Materials and Methods: Our study includes the results of 1371 gastroduodenoscopies carried out in 2008, for patients between 65 and 92 years old, the study includes both kind of patients who were admitted to hospital and those who were investigated on an outpatient basis. The main group includes 695 patients with various level of DGR severity, and the control group consists of 676 patients without DGR., Results: DGR was diagnosed in 14.8% more in women. In case of the presence of DGR we have found changes in the antrum mucosa as congestion, and minor erosion, hyperplasia, metaplasia of gastric and esophageal mucosa, and stomach polyps. And we have not noticed such changes when DGR was absent. We have found that the high frequency of antral hyperplasia is correlated to the DGR severity., Conclusion: DGR is diagnosed in more than 10% of patients who undergo gastroduodenoscopy. DGR is an indicator of conditions often associated with various morphological changes in gastric mucosa; therefore this finding has to be taken in consideration in the further investigations and management of such patients.

The article examines the state of the antral mucosa of the stomach in 43 young patients with duodeno-gastric reflux without any clinical manifestations. In 69.9% of investigated revealed changes in the gastric mucosa, characteristic of reflux gastritis. The comparative characteristic of stereometric indicators of cellular elements, infiltrated own plate of a mucous membrane of a stomach is spent at a reflux-gastritis and the mixed gastritis (at presence Helicobacter pylori). Article is illustrated by 2 tables.

In patients with the chronic gastritis in a combination with opisthorchiasis and with duodenogastric reflux it was marked the more expressed endoscopic and histological changes of stomach mucosa in comparison with the patients without reflux. In the patients with chronic gastritis and DGR the small colonization degree of mucosa by H. pylori was marked. The combination of endoscopic and histological changes in stomach mucosa at DGR allows to recommend the endoscopy as the basic method in clinical practice.
