OBJECTIVE: to evaluate the influence of Duodenal reflux in histological changes of the gastric mucosa of rats infected with Helicobacter pylori submitted to pyloroplasty. METHODS: after two weeks of acclimation, we infected 30 male Wistar rats with Helicobacter pylori. We randomly divided them into three groups: one submitted to pyloroplasty, another to partial gastrectomy and the third, only infected, was not operated. After six months of surgery, euthanasia was carried out...

Gastric stump cancer (GSC) is the malignant tumor that develops in the gastric remnant after partial gastrectomy was performed both for benign and malignant lesions. This paper presents the results of the case studies from the scientific literature, which focused on GSC, and has been published in the last 10 years. The search was performed with the help of the specific tools offered by the international databases. The subject was approached because of the constant rising incidence of GSC in the past few years, now reaching values between 1% and 7%...

Psychogenic stress in rabbits caused dysmotility of the gastroduodenal zone: inhibition of contractile activity (CA) in antral and pyloric parts of the stomach simultaneously with the increase of CA in proximal and distal parts of duodenum. Stress induced inhibition of the gastric contractile activity is substantially "non-adrenergic non-cholinergic" and only in the initial phase of the reaction it appears to be "α-adrenergic". The strengthening of CA in the proximal duodenum resulted from the direct exciting action of endocrine stress factor on the smooth muscle of the gut...

The incidence of reflux esophagitis increases in world, affecting approximately 20% of western populations and its consequent lesion, Barrett's esophagus (BE), established as the primary precursor lesion of esophageal adenocarcinoma (EAC) or Barrett associated adenocarcinoma (BAA), is also increasing in incidence in Asian countries as well as Western countries. The fact that surveillance strategies have not had a major benefit in decreasing the incidence of EAC increased attention to arrest or delay the progression of BE to EAC...

Remnant gastric cancer (RGC) and gastric stump cancer after distal gastrectomy (DG) are recognized as the same clinical entity. In this review, the current knowledges as well as the non-settled issues of RGC are presented. Duodenogastric reflux and denervation of the gastric mucosa are considered as the two main factors responsible for the development of RGC after benign disease. On the other hand, some precancerous circumstances which already have existed at the time of initial surgery, such as atrophic gastritis and intestinal metaplasia, are the main factors associated with RGC after gastric cancer...

Comparative analysis of dissemination by H. pylori of the bile portions in patients of a control group, suffering an acute calculous cholecystitis (ACCH), was performed. Dissemination of H. pylori in a control group was significantly less, than in a bile portions of patients, suffering ACCH. While analyzing the rate and degree of dissemination by H. pylori of the gastic and gallbladder mucosa biopsies of patients, suffering chronic non-calculous cholecystitis, associated with duodenogastric reflux and gastroduodenitis, bacteria were revealed trustworthy more often and in more number, than in a gallbladder mucosa in patients, suffering ACCH...

Gastrointestinal (GI) disorders often manifest similar symptoms with overlapping clinical diagnosis and unmet medical needs. Traditional Chinese medicine (TCM) has history-proven benefits for GI diseases; albeit language barrier prevents Western readers from accessing the original reports in Chinese. The TCM formula Si-Ni-San (SNS) consists of 4 herbs targeting on homeostatic disturbances characterized by "reflux" and "irritable" problems. Here we used SNS as a therapeutic tool to explore the common mechanisms of pathogenesis in non-neoplastic GI diseases...

Clinically significant dysplasia of connective tissue in patients with celiac disease is often responsible for various visceral disorders. Different disturbances of motor and evacuation functions are often determined in this patients (gastroesophageal reflux, duodenogastral reflux, spastic and hyperkinetic dyskinesia). The clinical course of the celiac disease, associated with connective tissue dysplasia, is characterized by asthenovegetative syndrome, reduced tolerance to physical activity, general weakness, fatigue and emotional instability...

Background. Previous studies have established norms of 24-hour gastric pH profiles for western countries. This study was designed to establish the pattern for a rural African population with a high incidence of oesophageal cancer. Methods. After lower oesophageal manometry a probe was placed 10 cm distal to the lower oesophageal sphincter. We carried out 24-hour ambulatory monitoring of gastric pH on 59 healthy subjects. This was satisfactorily completed on 26 female and 18 male (age 21-64, median 35) subjects in the Transkei region of South Africa...

BACKGROUND: Both esophageal atresia (EA) and duodenal atresia (DA) involve deficient anti-reflux barrier, poor esophageal function and eventually, duodenogastric reflux. This study aims at examining the upper gastrointestinal functional status in a cohort of patients with both EA and DA. METHODS: A retrospective survey of patients treated for EA and DA between 1965 and 2012 was conducted. Clinical charts, office visits, imaging, upper gastrointestinal endoscopy and esophageal pH metry/impedance were used to assess the long-term condition of the esophagus, the presence of gastroesophageal reflux disease (GERD) and/or the need for fundoplication...

Recent advances in diagnostic techniques have allowed the diagnosis of gastric cancer (GC) at an early stage. Due to the low incidence of lymph node metastasis and favorable prognosis in early GC, function-preserving surgery which improves postoperative quality of life may be possible. Pylorus-preserving gastrectomy (PPG) is one such function-preserving procedure, which is expected to offer advantages with regards to dumping syndrome, bile reflux gastritis, and the frequency of flatus, although PPG may induce delayed gastric emptying...

Introduction: The gastrooesophageal reflux disease (GERD) is a possible cause of chronic cough. The laparoscopic fundoplication is well established in the treatment of GERD. In a retrospective study, the effectivity of this operation on the GERD associated cough was examined and possible preoperative predictive factors concerning the post-surgical therapy effect were characterized. Patients and Methods: 85 patients after laparoscopic fundoplication due to GERD treated with proton pump inhibitors without (RS-H: n = 31) or with associated cough (RS+H: n = 54) were evaluated in a three-month follow-up by data analysis regarding an indication point score from typical symptoms as well as findings (gastroscopy, histology, 24-hour oesophagus pH-metry)...

The long-term use of proton pump inhibitors (PPIs) exacerbates corpus atrophic gastritis in patients with Helicobacter pylori (H. pylori) infection. To identify a potential mechanism for this change, we discuss interactions between pH, bile acids, and H. pylori. Duodenogastric reflux, which includes bile, occurs in healthy individuals, and bile reflux is increased in patients with gastroesophageal reflux disease (GERD). Diluted human plasma and bile acids have been found to be significant chemoattractants and chemorepellents, respectively, for the bacillus H...

Gastroesophageal reflux (GER) frequently occurs in patients with respiratory disease and is particularly prevalent in patients with cystic fibrosis. GER is a condition in which the duodenogastric contents of the stomach leak into the esophagus, in many cases resulting in aspiration into the respiratory tract. As such, the presence of GER-derived bile acids (BAs) has been confirmed in the bronchoalveolar lavage fluid and sputum of affected patients. We have recently shown that bile causes cystic fibrosis-associated bacterial pathogens to adopt a chronic lifestyle and may constitute a major host trigger underlying respiratory infection...

It was done the comparative analysis of the morphofunctional state of the upper gastrointestinal tract between 350 patients with effective conservative treatment and 104 patients with hard scarring gastric ulcers. The analysis identified the predictors of ineffective medical treatment and led to deliver the indications for timely surgical treatment. It was identified the next indications for planned organ-preserving surgical treatment of patients with hard scarring gastric ulcers: penetrating and non-healing ulcers with large or gigantic size in case of the adequate medical therapy, high-grade dysplasia and colonic metaplasia of the gastric epithelium in the borders or fundus of the ulcer,ulcers combination with fixed cardio-fundal or fundo-corporal hiatal hernias; hypotonic-hypokinetic type of the gastric and duodenal activity with the development of gastrostasis and pronounced duodenogastric reflux...
