Abstract
Objective. To study etiopathogenetic aspects of biliary reflux-gastritis (RG) and develop modern principles of its therapy depending on acidity of stomach contents, atrophy ofgastric mucosa, and Helicobacter pylori infection. Different pathogenetic mechanisms of RG are discussed with special reference to bile flow into the antrum as a result of duodenogastric reflux. It is shown that the use of de-nol and probiotic ProBiotic Complex for the treatment of biliary reflux-gastritis increases effectiveness of H. pylori eradicationby 18.2% and prevents the development of bowel dysbiosis.

Abstract
Ultrasonography has been widely used to evaluate duodenogastric reflux (DGR). But to the best of our knowledge, no automatic analysis system was developed to realize the quantitative computer-aided analysis. In this paper, we propose a system to perform the automatic detection of DGR in the ultrasonic image sequences by applying the automatic motion analysis. The motion field is estimated based on image velocimetry. Then, an intelligent motion analysis is applied. For the DGR detection, the motion and structural information is combined to analyze the transploric motion of the fluid. In order to test the performance of the proposed system, we designed the experiment with the real and synthetic ultrasonic data. The proposed system achieved a good performance in the DGR detection. The automatic results were accordant with the gold standard in analyzing the fluid motion. The proposed system is supposed to be a promising tool for the study and evaluation of DGR.

Abstract
AIM To study the specific features of the clinical course of gastroesophageal reflux disease (GERD) associated with duodenogastroesophageal reflux (DGER) in patients with chronic acalculous cholecystitis (CAC) and cholelithiasis (CL), as well as qualitative and quantitative characteristics. SUBJECTS AND METHODS The clinical, morphological, motor tonic characteristics of the esophagogastroduodenal area, mucosal microbial biocenosis in the esophagus, stomach, and duodenum were studied in detail in 83 patients with GERD that was associated with DGER and ran concurrently with CAC or CL. RESULTS Impaired duodenal propulsive activity as a concomitance of the signs of gastrostasis and duodenal dyskinesia with dyscoordination of both anthroduodenal and duodenojejunal propulsion and with the development of duodenogastric reflux and DGER, which in turn determine esophageal and gastric pH values is shown to be of importance in CAC and CL, which match GERD. Abnormal microbiocenosis in the upper digestive tract is characterized by the higher quantitative and qualitative content of the mucous microflora. Opportunistic microorganisms exhibit cytotoxic, hemolytic, lecithinase, caseinolytic, urease, and RNAase activities. CONCLUSION The found specific features of the course of GERD associated with DGER in patients with biliary tract abnormalities lead us to search for novel therapeutic approaches based on the correction of digestive motor tonic disorders and abnormal microbiocenoses of the mucous flora in the esophagus, stomach, and duodenum.

Abstract
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.

Abstract
AIM To study the clinical and pathogenetic types of gastroesophageal reflux disease (GERD) in terms of different types of reflux into the esophagus, their risk factors and predictors. MATERIALS AND METHODS The clinical, morphological, motor tonic characteristics of the esophagogastroduodenal area, the phenotypic and visceral signs of existing undifferentiated connective tissue dysplasias (UDCTD), and the suprasegmental and segmental autonomic apparatus were studied in detail in 124 patients with GERD. RESULTS Two clinical and pathogenetic types of GERD associated with the predominance of gastroesophageal or duodenogastroesophageal refluxes (GER and DGER) are identified. The type of the disease running in the predominance of GER develops in subjects with the high rate of visceral stigmas of UDCTD--cardiac failure and hiatal hernias, sympathetic autonomic tone in the digestive system. The feeding preference of piquant and spicy dishes and spices serves to realize the predictors of this type. The DGER-associated type develops in subjects with a concurrence of sympathetic and parasympathetic total autonomic tones in the digestive system in the presence of preexisting biliary tract diseases, including abnormalities in the structure of the gallbladder as visceral signs of UDCTD and it is realized in the feeding preference of high-calorie dishes. CONCLUSION It is promising to study the autonomic status and the signs of UDCTD as structural and functional predictors of GERD and its types for the prediction of the disease, professional orientation, and the acquisition of eating behavior primarily in young people.

Abstract
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.

Abstract
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.

Abstract
To study the impact of Opisthorchis infestation on the upper digestive tract and small bowel in chronic inflammatory bowel diseases, the authors examined 164 patients with inflammatory bowel diseases, including 71 patients with ulcerative colitis and 45 with Crohn's disease without parasitosis and 48 with chronic opisthorchiasis (31 with ulcerative colitis and 17 with Crohn's disease). A control group consisted of 20 healthy individuals and 20 patients with chronic opisthorchiasis. A diagnosis was established by colonofibroscopy and a morphological study of colonic biopsy specimens. Gastric mucosal atrophic changes and motor evacuatory disorders as duodenogastric reflux were significantly more frequently encountered in inflammatory bowel diseases concurrent with chronic opisthorchiasis. The presence of Opisthorchis infestation significantly worsened fat and carbohydrate malabsorption in the small bowel in inflammatory bowel diseases.

Abstract
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.

Abstract
Duodenogastric reflux (DGR) was revealed in 52.6% patients, suffering recurrent postoperative complicated duodenal ulcers (RPOCDU). Pylorodestructive operations performance, pyloric involvement into ulcerative infiltrate and absence of chronic duodenal impassability (CHDI) correction during the first operation done had constituted the DGR occurrence causes. While establishing the indications for elective operation performance as well as choosing the surgical method of the RPOCDU treatment it is necessary to take into account the presence and severity degree of DGR. Surgical treatment of DGR must obligatory include not only the pyloric preservation and strenghtening, but the CHDI correction as well. Selective periarterial sympathectomy of duodenum constitutes an effective method, improving her tone without pyloric innervations disturbing.

Abstract
AIM To investigate disorders of psychoemotional functions, humoral regulation (substance P) and duodenal motility (DM) in patients with combined refluxes for their differential correction. MATERIAL AND METHODS A total of 60 patients with gastroesophageal and duodenogastric refluxes were examined. RESULTS Patients with reflux disorders had more frequent and severe neurotic reactions. Humoral changes are associated with characteristics of psychoemotional regulation. The risk of subnormal levels of the substance P rises substantially in changes in the scales of anxiety, neurotic depression, hysterical reaction and autonomic disorders. Segmental duodenal motility regresses with lowering of plasmic levels of substance P. CONCLUSION Patients with combined reflux disorders have psychoemotional disorders, abnormal humoral regulation and duodenal motility necessitating a differential approach to treatment of such patients.

Abstract
OBJECTIVE Duodenogastric reflux (DGR) is a reverse flow of duodenal juice into stomach through pylorus composed of bile acid, pancreatic secretion, and intestinal secretion. The increased entero-gastric reflux results in mucosal injury that may relate not only to reflux gastritis but also esophagitis, gastric ulcers, carcinoma of stomach and esophagus. However, the exact mechanisms of gastric mucosal damage caused by DGR are still unknown. The objective of the present study is to investigate the pathogenic effect of primary DGR on gastric mucosa in children, and to explore the correlation of DGR with clinical symptoms, Hp infection and intragastric acidity. METHOD Totally 81 patients with upper gastrointestinal manifestations were enrolled and they were graded according to the symptom scores and underwent endoscopic, histological examinations and 24-hour intra-gastric bilirubin was monitored with Bilitec 2000. Of the 81 cases, 51 underwent the 24-hour intra-gastric pH monitoring by ambulatory pH recorder simultaneously. The total fraction time of bile reflux was considered as a marker to evaluate the severity of DGR. The total fraction time of bile reflux was compared between the patients with positive and negative results under endoscopy and histologically, respectively. The correlations of the total fraction time of bile reflux with clinical symptom score, Hp infection, intragastric acidity were analyzed respectively. RESULT The total fraction time of bile reflux in the patients with hyperemia and yellow stain gastric antral mucosa under endoscopy was significantly higher than that without those changes [17.1% (0.5% approximately 53.2%) vs. 6.5% (0 approximately 58.6%), Z = -1.980, P < 0.05; 19.8% (0.5% approximately 58.6%) vs. 8.8% (0 approximately 38.0%), Z = -2.956, P < 0.01 respectively]. Histologically, the cases with intestinal metaplasia had significantly higher total fraction time of bile reflux than in the cases without intestinal metaplasia [29.0% (1.9% approximately 58.6%) vs. 14.3% (0 approximately 53.7%), Z = -2.026, P < 0.05], but no significant difference was found either between the cases with and without chronic inflammation (P > 0.05) or between the cases with and without active inflammation (P > 0.05). The severity of bile reflux was positively correlated with the score of abdominal distention (r = 0.258, P < 0.05), but no correlation with either the severity of intragastric acid (r = -0.124, P > 0.05), or Hp infection (r = 0.016, P > 0.05) was found. CONCLUSION Primary DGR could cause gastric mucosal lesions manifested mainly as hyperemia and bile-stained gastric antral mucosa under endoscopy and the gastric antral intestinal metaplasia histologically in children. There was no significant correlation between DGR and gastric mucosal inflammatory infiltration. DGR had no relevance to Hp infection and intragastric acidity. We conclude that DGR is probably an independent etiological factor and might play a synergistic role in the pathogenesis of gastric mucosal lesions along with gastric acid and Hp infection.

Abstract
Painful abdominal syndrome and diurnal fluctuations of pH values were investigated in 125 patients with different clinical variants of duodenal ulcer disease (DUD) in the phase of exacerbation. Fifty patients had uncomplicated DUD; it was complicated in the remaining 75 patients. The clinical course of the uncomplicated disease was characterized by moderate to severe painful hyperacidity syndrome coincident with the period of exacerbation, marked daily variations of pH, and manifest duodenogastric reflux (DGR). These made the patients opportunely apply for medical aid while acidification and alkalinization processes in the stomach prevented the development of complications. The complicated disease was associated with short-term pain or its absence, monotonic diurnal variations of acid production and alkalinization, weak DGR. Taken together, these clinical features explain why such patients less frequently apply for medical aid and eventually develop destructive complications.

Abstract
BACKGROUND/AIMS Recent studies have shown that reflux of the duodenal content to the esophagus plays an important role in esophageal mucosal damage. The aim of the study is to compare the duodenogastroesophageal (DGER) reflux with the severity of reflux esophagitis and evaluate its response to either medical and/or antireflux surgery. METHODOLOGY Ninety-six patients with DGER were subjected to thorough history, upper GI endoscopy, barium study, esophageal manometry and 24-hr esophageal pH metry combined with Bilitec 2000. Medical treatment was given for all, while Nissen fundoplication was done for 28 patients. All patients were evaluated after Nissen fundoplication and treatment. RESULTS The age of studied patients was 36.26+/-12.7 years with male to female ratio 2:1. The chief symptom was heartburn in 73 (76%) patients. Upper GI endoscopy revealed, 30 (31.2%) patients had grade I reflux, 30 (31.2%) patients had grade II reflux, 7 patients had grade III reflux, 5 patients had grade VI reflux, Barrett's esophagus in 14 patients (14.5%), hiatus hernia (HH) in 26 (27%) patients. Barium study revealed that, 40 (41.6%) patients had evidence of reflux, while 34 (35.4%) patients had reflux with HH. Esophageal motility revealed the mean LESP (12.7+/-7.6), 68 patients (70.8%) had normotensive body while ineffective esophageal body motility was encountered in 28 (29.1%) patients. Esophageal 24-hr pH study and Bilitec 2000 revealed that 54 (56.2%) patients had bile reflux with pathological acid reflux, while 42 (43.7%) patients had bile reflux in alkaline pH. Medical treatment gave excellent to good response in 68 (70.8%) patients, while Nissen fundoplication was done for 28 (29.2%) patients. Endoscopic examination 6 months after Nissen fundoplication showed marked improvement in endoscopic injury. Barium study after Nissen fundoplication revealed repair of HH and control of GERD in all patients except one. Esophageal motility, 24 hr pH study and Bilitec 2000, after 6 months of Nissen shows high significant increase in LESP, decrease in acid and bile reflux. No significant difference between open or laparoscopic fundoplication in LESP, acid and bile reflux. CONCLUSIONS DGER in acid medium is more injurious to the esophagus than DGER in alkaline pH. The severity of esophageal injury does not correlate with the severity of acid or bile reflux but has a direct correlation with impaired distal esophageal motility. Medical treatment gives satisfactory control of symptoms and healing of esophageal lesion in 70% of DGER. The response to medical treatment does not depend on the severity of esophageal injury but depends on the severity of bile and acid reflux. Nissen fundoplication in refractory patients, either open or laparoscopic, was effective in control of heartburn in 95% of patients contrary to 50% in mixed symptoms.

Abstract
INTRODUCTION The aim of the study was to analyse pH- and bile-monitoring data in patients with Barrett's esophagus and in age- and gender-matched controls. SUBJECTS AND METHODS Twenty-four consecutive Barrett's patients (8 females, 16 males, mean age 57 years), 21 patients with esophagitis (10 females, 11 males, mean age 58 years), and 19 healthy controls (8 females, 11 males, mean age 51 years), were included. Only patients underwent endoscopy with biopsy. All groups were investigated with manometry, gastric and esophageal 24-h pH, and simultaneous bile monitoring according to a standardized protocol. A bilirubin absorption>0.25 was determined as noxious bile reflux. The receiver operator characteristic (ROC) method was applied to determine the optimal cutoff value of pathologic bilirubin levels. RESULTS Of Barrett's patients, 79% had pathologic acidic gastric reflux (pH<4>5% of total measuring time). However, 32% of healthy controls also had acid reflux (p<0.05) without any symptoms. The median of esophageal bile reflux was 7.8% (lower quartile (LQ)-upper quartile (UQ)=1.6-17.8%) in Barrett's patients, in patients with esophagitis, 3.5% (LQ-UQ=0.1-13.5), and in contrast to 0% (LQ-UQ=0-1.0%) in controls, p=0.001. ROC analysis showed the optimal dividing value for patients at more than 1% bile reflux over 24 h (75% sensitivity, 84% specificity). CONCLUSION An optimal threshold to differentiate between normal and pathological bile reflux into the esophagus is 1% (24-h bile monitoring with an absorbance>0.25).

Abstract
BACKGROUND Barrett's oesophagus (BO), a premalignant condition associated with the development of oesophageal adenocarcinoma (OAC), is thought to be a consequence of chronic duodeno-gastro-oesophageal reflux. Of the refluxates, bile acids, either alone or in combination with acid, are probably the most important. METHODS Analysis of the literature on the role played by bile acids in inducing BO and/or progression to OAC. RESULTS Combined pH and Bilitec 2000 (as a measure of bile reflux) monitoring and oesophageal aspiration studies in humans suggest a combined role for bile acids, particularly taurine conjugated bile acids, in causing oesophageal mucosal injury. Evidence from animal models has demonstrated that duodenal juice alone is also able to induce BO and/or OAC. Likewise, ex vivo studies with biopsies from BO patients show that increased proliferation and cyclo-oxygenase-2 expression are present after a pulsed exposure to acid or conjugated bile acids, but not if acid and bile acids are combined. Proton-pump inhibitors (PPIs) have been shown to decrease the biliary component of the refluxate. There is some evidence that PPIs are able to reduce neoplastic progression in BO. On the other hand, chronic PPIs can also stimulate bacterial overgrowth, which can result in increased production of secondary bile acids, particularly deoxycholic acid, in the stomach. Deoxycholic acid has been demonstrated to have a tumour-promoting capacity. CONCLUSIONS It is unknown what factors of the refluxate (acid and/or bile) induce BO and/or promote carcinogenesis, but there is evidence that secondary bile acids play a role. A better understanding of the molecular steps involved in the induction of BO, and the role of bile acids herein, may identify targets at which preventive therapies can be directed.

Abstract
OBJECTIVE To assess the long-term results of the duodenal switch operation made for pathologic transpyloric duodenogastric reflux (DGR). SUMMARY BACKGROUND DATA DGR symptoms and lesions are poorly responsive to medical treatment. METHODS A duodenal switch operation was made on 48 patients suffering from pathologic transpyloric DGR either unrelated (n = 28) or secondary (n = 20) to previous upper gastrointestinal (GI) surgery, including cholecystectomy or vagotomy. The diagnosis was based on the combination of several objective arguments: a long history of gastric symptoms (ie, nausea, epigastric pain, and/or bilious vomiting) poorly responsive to medical treatment (48 of 48), gastroesophageal reflux symptoms unresponsive to proton-pump inhibitors (PPI) (23 of 29), gastritis on upper GI endoscopy (37 of 48) and/or at histology (28 of 41), presence of a bilious gastric lake at >1 upper GI endoscopy (30 of 48), DGR at diisopropyl iminodiacetic acid (DISIDA) scintigraphy scanning (7 of 13), pathologic 24-hour intragastric bile monitoring with the Bilitec device (40 of 41), and absence of Helicobacter pylori antral infection (39 of 41). RESULTS At follow-up (median, 81 months), gastric symptoms were nil, had improved, and remained unchanged in 29 (60.4%), 16 (33.3%), and 2(4.2%) patients, respectively, and 1 patient experienced symptomatic recurrence after a 92-month symptom-free period (2.1%). Among the 44 patients who had postoperative upper GI endoscopy, 42 (95.5%) had no gastritis whereas 5 (11.3%) had an ulcer at the duodenojejunostomy. Gastric exposure to bile at postoperative 24-hour intragastric Bilitec test in 36 patients was nil, within the normal range, and still slightly pathologic in 15 (41.7%), 19 (52.8%), and 2 (5.5%), respectively. CONCLUSIONS The duodenal switch operation made on patients in whom diagnosis of pathologic transpyloric DGR is supported by several objective arguments provides most of them with symptomatic and endoscopic improvement parallel to abolishment or normalization of gastric exposure to bile. Postoperative PPI therapy during a 2-month period is to be recommended to prevent the development of an anastomotic ulcer.

Abstract
BACKGROUND Bile in the oesophagus occurs frequently in patients with gastro-oesophageal reflux disease (GORD) and has been linked to Barrett's metaplasia and cancer. Although duodenogastric reflux is a prerequisite for bile in the oesophagus, little is known about its importance in GORD. METHODS Some 341 patients with GORD were assessed by simultaneous 24-h gastric and oesophageal bilirubin monitoring. Definitions of increased bilirubin exposure were based on the 95th percentiles in healthy volunteers. The relationship between gastric and oesophageal bilirubin exposure and the correlation with disease severity were analysed. RESULTS Of the 341 patients with GORD, 130 (38.1 per cent) had increased gastric and 173 (50.7 per cent) had increased oesophageal bilirubin exposure. Of the 173 patients with bile in the oesophagus, 89 (51.4 per cent) had normal and 84 (48.6 per cent) had increased gastric bilirubin exposure. Of these 84 patients, 75 (89 per cent) had oesophagitis or Barrett's oesophagus (P = 0.003). These effects were mainly related to differences in supine reflux. CONCLUSION Bile in the oesophagus originates from either normal or increased gastric bilirubin exposure. Patients with increased duodenogastric reflux are more likely to have oesophagitis or Barrett's oesophagus. These findings highlight the role of duodenogastric reflux as an additional factor in the pathogenesis of GORD.

Abstract
AIM To study function of the liver, sphincter system and the gall bladder (GB) in patients with biliary dyskinesia (BD). MATERIAL AND METHODS Thirty-four patients with BD have undergone clinical, fibrogastroduodenoscopic examinations, fractional duodenal intubation with examination of the bile, ultrasonography, dynamic scintigraphy of the hepatobiliary system. RESULTS The examination of the patients has detected GB hypotonia (65%), GB hypertension (35%), Oddi's sphincter hypertention (28%), Oddi's sphincter hypotonia (44%), Lutkens' sphincter hypertonicity (19%), Lutkens' sphincter hypotonia (13%), impairment of intrahepatic biliary tracts (65%), lithogenic bile (100%), duodenogastric reflux (41%). CONCLUSION Consecutive use of duodenal tubing, ultrasonography and hepatobiliscintigraphy provide assessment of defects in the function of the liver, biliary tract and sphincter system in patients with BD.

Abstract
This study reviews current data regarding duodenogastric and gastroesophageal bile reflux-pathophysiology, clinical presentation, methods of diagnosis (namely, 24-hour intraluminal bile monitoring) and therapeutic management. Duodenogastric reflux (DGR) consists of retrograde passage of alkaline duodenal contents into the stomach; it may occur due to antroduodenal motility disorder (primary DGR) or may arise following surgical alteration of gastoduodenal anatomy or because of biliary pathology (secondary DGR). Pathologic DGR may generate symptoms of epigastric pain, nausea, and bilious vomiting. In patients with concomitant gastroesophageal reflux, the backwash of duodenal content into the lower esophagus can cause mixed (alkaline and acid) reflux esophagitis, and lead, in turn, to esophageal mucosal damage such as Barrett's metaplasia and adenocarcinoma. The treatment of DGR is difficult, non-specific, and relatively ineffective in controlling symptoms. Proton pump inhibitors decrease the upstream effects of DGR on the esophagus by decreasing the volume of secretions; promotility agents diminish gastric exposure to duodenal secretions by improving gastric emptying. In patients with severe reflux resistant to medical therapy, a duodenal diversion operation such as the duodenal switch procedure may be indicated.

Abstract
BACKGROUND The role of duodenogastric reflux in the genesis of gastric polyps in familial adenomatous polyposis (FAP), although suggested by scintigraphy scanning studies, remains unclear. METHODS Twenty-four hour intragastric bilirubin monitoring with the Bilitec optoelectronic device was carried out in 25 FAP patients, of whom 19 had gastric polyps (fundic gland in 13, adenomatous in 2, and both histologic types in 4) on endoscopic examination. Gastric exposure to bilirubin was expressed as the percentage of total recording time that absorbance exceeded the threshold of 0.25 and was calculated in reference to values obtained from 25 healthy volunteers. Helicobacter pylori status of the stomach was checked as well. RESULTS Gastric exposure to bilirubin was pathologic in 14 (56%) patients. Gastric exposure to bilirubin was of longer duration in FAP patients than in healthy volunteers (mean+/-SEM: 19%+/-4% vs 6%+/-2%) (P<.005). It increased from healthy volunteers (6%+/-2%) to FAP patients without gastric polyps (10%+/-3%), and to FAP patients with gastric polyps (22%+/-5%) (P<.004). Bilirubin exposure times were similar in FAP patients with fundic gland polyps only and in those having either adenomatous polyps only or both types of polyps (24%+/-7% vs 17%+/-4%). No patient with pathologic gastric exposure to bilirubin as well as none having gastric polyps, had H. pylori in the antrum. CONCLUSIONS This study shows that gastric exposure to bilirubin is of longer duration in FAP patients than in healthy volunteers, and in FAP patients with gastric polyps than in those without polyps. This study supports the existence of a direct correlation between pathologic duodenogastric reflux (DGR), the absence of H. pylori in the antrum, and the presence of gastric polyps in FAP patients.

Abstract
Ambulatory pH monitoring detects abnormal levels of acid reflux in the oesophagus and can be used to correlate patients' symptoms with oesophageal acid exposure. Catheter-based pH testing has several limitations, including issues of sensitivity, specificity, tolerability and the inability to record non-acid reflux events. In an effort to improve upon these drawbacks, several devices have been introduced, including the Bilitec system for measuring duodenogastro-oesophageal reflux; intraluminal impedance monitoring, which detects the distribution, composition and clearing of both acid and non-acid oesophageal reflux; and a wireless pH monitoring device, the Bravo capsule. Initial investigations using the Bilitec system demonstrated that duodenogastro-oesophageal reflux tracked very closely with acid reflux and decreased with proton-pump inhibitor (PPI) therapy, casting doubt on the clinical utility of Bilitec monitoring. Recent evidence revealed a possible role for duodenogastro-oesophageal reflux in a subset of patients who continue to report reflux symptoms in the setting of normalized oesophageal acid exposure on high-dose PPI therapy. When combined with pH monitoring, impedance monitoring enhances the detection and characterization of gastro-oesophageal reflux and may have a role in the evaluation of certain specific gastro-oesophageal reflux disease (GERD) symptoms that persist despite acid suppression therapy. The utility of the Bravo wireless technology for GERD diagnosis has been validated in several studies, with improvements over catheter-based pH monitoring in tolerability, accuracy and sensitivity, as well as the ability to record periods both off and on PPI therapy in a single study. All three diagnostic modalities have advanced the understanding of GERD pathogenesis, but their impact on the clinical management of GERD is still the focus of active investigation.

Abstract
Gastro-oesophageal reflux disease is defined as the presence of symptoms or lesions that can be attributed to the reflux of gastric contents into the oesophagus. Aspiration and prolonged monitoring studies in humans have shown that reflux of gastric contents is comprised of both acid and non-acid components, in healthy as well as diseased people. Methods to monitor the non-acid component of the refluxate are described in detail. Experimental models suggest that synergism between acid and pepsin and conjugated bile acids have the greatest damaging potential for oesophageal mucosa, although unconjugated bile acids may be caustic at a more neutral pH. Human studies are compatible with a synergistic action between acid and duodenogastric reflux in inducing lesions. During prolonged monitoring studies, typical gastro-oesophageal reflux disease symptoms are more related to acid reflux events than to non-acid reflux events. However, symptoms that persist during acid-suppressive therapy are often related to non-acid reflux events. The therapeutic options for the non-acid component of the refluxate, including acid suppression, prokinetics, baclofen and surgery, are discussed.

Abstract
OBJECTIVE Although stomach is the best choice for reconstruction after esophagectomy from the viewpoint of safety and ease, an intrathoracic stomach, nevertheless, is a poor long-term substitute. This anatomical configuration abolishes normal antireflux mechanisms and places the acid-excreting stomach subject to biliary reflux, moreover, in an adjacent position to the esophagus within the negative-pressure environment of the thorax. METHODS Between 1995 and 2002, 27 patients with high-grade neoplasia-as early Barrett's carcinoma-or non-dilatable peptic stricture underwent limited surgical resection of the distal esophagus and esophagogastric junction. In 11 of these cases, the reconstruction was performed with gastro-jejuno-duodenal interposition. The long-term functional results of this specially adapted form of interposition reconstruction have been evaluated. The postoperative follow-up period ranged between 24 and 95 months (mean 68 months). Nine patients (9/11=81.8%) have agreed to undergo endoscopy, radiographic contrast-swallow examination, and 24-h ambulatory esophageal pH and bilirubin monitoring. RESULTS Three out of nine patients (3/9=33%) demonstrated abnormal levels of esophageal acid exposure during the 24-h study period, whilst none had any evidence of bilirubin exposure in the esophageal remnant. Endoscopy revealed that three patients had reflux esophagitis in the remnant esophagus: Los Angeles A=2, C=1. No stomal or jejunal ulceration at the gastro-jejunal anastomosis could be observed. Histopathologic assessment of the squamous epithelial biopsies demonstrated microscopic evidence of inflammation: minor in two cases, moderate in one and major in one case; however, none of them had evidence of columnar metaplasia in the esophageal remnant at a median of 68 months after surgery. The majority of the patients have been doing well since the operation: 8/9 (88%)=Visick I-II. CONCLUSIONS Gastro-jejuno-duodenal interposition represents an adequate 'second-best' method of choice if technical difficulties emerge with jejunal or colon interposition following limited resection of the esophagus performed due to early Barett's carcinoma or non-dilatable peptic stricture.

Abstract
Gastroesophageal reflux (GER), through the occurrence of gastroesophagopharyngeal reflux (GEPR), is an established cause of several otorhinolaryngological (ORL) manifestations. It has been suggested that unexplained excessive throat phlegm might also be a manifestation of GER, but formal evidence is lacking. The aim of the present study was to investigate the prevalence of GER as well as duodenogastroesophageal reflux (DGER) in consecutive patients with chronic complaints of excessive throat phlegm. Fifty-nine consecutive patients with chronic unexplained excessive throat phlegm, transparent in 33 patients (TTP) and yellow in 26 patients (YTP), underwent gastrointestinal endoscopy, 24-hr dual esophageal pH monitoring, and fiberoptic DGER monitoring. Proximal esophageal DGER monitoring was performed in seven YTP patients and analysis of bile acids in throat phlegm was performed on 16 samples. The effect of high-dose acid suppressive therapy was evaluated at 2-week intervals. Endoscopy and pH monitoring established a diagnosis of pathological GER in 75% of the patients. Pathological DGER was present in 56% of the patients and this was associated with YTP. Proximal DGER exposure was high in all investigated subjects and chemical analysis revealed a median bile acid concentration of 0.184 microM in nine YTP samples and no detectable bile acids in seven TTP samples. After a median of 4 weeks of acid suppressive therapy, most patients improved and 61% became asymptomatic. YTP patients were more likely to require maintenance acid suppressive therapy than TTP patients. Unexplained excessive throat phlegm is a sign suggestive of GER and GEPR, and unexplained yellow throat phlegm a sign suggestive of duodenogastroesophagopharyngeal reflux (DGEPR).

Abstract
BACKGROUND Recent studies suggest that duodeno-gastro-oesophageal reflux (DGER) contributes to the occurrence of reflux oesophagitis and Barrett's oesophagus. The mechanisms underlying duodeno-gastric reflux (DGR), a prerequisite for DGER, are poorly understood. AIMS To study the occurrence of DGR in relation to interdigestive and postprandial gastroduodenal motility. SUBJECTS AND METHODS Ten healthy subjects underwent stationary gastroduodenal manometry with simultaneous duodenal and antral Bilitec recording 4 h before and 5 h after ingestion of a liquid meal. Eight volunteers underwent the same study, with administration of erythromycin postprandially. RESULTS During the interdigestive phase II, all volunteers had short DGR episodes. Postprandially, DGR occurred in all subjects, on average 39 +/- 28 min after the start of the meal, and was cleared from the stomach after 242 +/- 23 min. Induction of increased antral motility and of a premature phase III, by administration of erythromycin, was associated with faster gastric DGR clearance. However, there was no direct temporal relationship between erythromycin-induced gastric phase III and erythromycin-induced DGR clearance. CONCLUSION In healthy subjects, duodenogastric reflux occurs sporadically in the interdigestive state and is a normal phenomenon in the postprandial period. Erythromycin induces faster clearance of DGR from the stomach, which depends on enhanced antral contractile activity rather than premature phase III.

Abstract
The intestine-specific caudal-related homeobox transcription factor Cdx2 is widely accepted to play a key role in intestinal development and differentiation in mammals. We studied the role of Cdx2 in the development of Barrett's esophagus (BE). In previous studies, we have shown a sequence of morphological changes of squamous epithelium leading to BE, found a peculiar metaplastic change common to other parts of gut, and proposed the concept of a "gut regenerative cell lineage" (GRCL). The GRCL is characterized by pyloric-foveolar metaplasia with goblet cell metaplasia, which occurs in the regenerative process in response to chronic inflammation. BE very likely develops through the GRCL, and we studied the expression of Cdx2 in various lesions of rat esophageal mucosa induced by duodenal reflux, using reverse transciptase-polymerase chain reaction and immunohistochemistry against Cdx2. We found that Cdx2 was expressed not only in specialized columnar epithelium (SCE) of BE, but also in several pyloric gland and foveolar metaplastic cells which developed in the basal layer of the squamous epithelium at an earlier stage of SCE development. These findings indicate that Cdx2 plays a crucial role in directing intestinal-type differentiation of the GRCL.

Abstract
INTRODUCTION It is widely accepted that long segments of Barrett's esophagus are caused by end-stage gastroesophageal reflux disease (GERD), but little is known about the correlation of severity of GERD and extent of metaplasia. METHODS Twenty normal volunteers and 142 patients with different extent of intestinal metaplasia (39 with intestinal metaplasia limited to the esophagogastric junction, 48 with short segments of Barrett's esophagus, and 55 with long segments) underwent manometry and combined pH-bilirubin monitoring. RESULTS The extent of intestinal metaplasia correlated to the exposition of gastric and duodenal juice in the esophagus and inversely with a competent lower esophageal sphincter. CONCLUSIONS The extent of intestinal metaplasia is related to the severity of GERD.

Abstract
In patients with superinvasion opisthorchiasis of prolonged invasion, 84% develop duodenal hypertension, 94% of the patients are found to have gastric hypertension; duodenogastric reflux with formation of chronic gastritis and reorganization is revealed in 75%. Reflux of gastric contents into the esophagus gives rise to chronic eosophagitis, regurgitation of intestinal contents into the pancreatic duct is a cause of chronic indurative pancreatitis of the head of the gland. In cases of duodenal hypertension, the rates of pancreatic O. felineus invasion are as high as 93.7%.

Abstract
Symptoms of functional dyspepsia demonstrate significant variability, among others dependently on the time of the day and on consumed meals. The aim of the study was to find out whether duodenogastric reflux is observed in subjects with nonulcer (NUD) and dysmotor dyspepsia (DD) and whether its intensification changes within 24 h. Investigations comprised 25 subjects with NUD and 25 with DD, aged 19-43 years after exclusion of other diseases and H. pylori infection. The gastric content of bilirubin was registered with Bilitec 2000 Synectics Medical. Duodenogastric reflux episodes were observed in both groups but their intensification and 24h dynamics were differentiated. In subjects with DD total reflux index was significantly higher than in those with NUD (mean=18.0+/-9.5% and mean=6.3+/-4.1%; p<0.05). These differences were particularly visible in after meal (mean=21.2+/-7.9% and mean=10.4+/-6.6%; p<0.01) and night time (mean=8.7+/-3.6% and mean=2.9+/-0.9%; p<0.01). The results of the study indicate that bilimetry may be useful in differentiation of the form of dyspepsia and in selection of rational therapy.

Abstract
To elucidate the histogenesis of gastric stump cancer, we performed an operation in rats to make all duodenal contents flow back into the glandular stomach. The subjects were 41 rats, and sequential morphological changes of the duodenogastric stoma and the incidence of stump cancers were studied. Serial sections around the stoma were studied with mucin stains such as paradoxical concanavalin A (Con A), galactose oxidase Schiff (GOS), and high-iron diamine-Alcian blue (HID-AB). An immunohistochemical study on cell proliferation with bromodeoxyuridine (BrdU) was also done. At week 30, pyloric gland type cells positive for Con A first appeared at the base of the intestinal crypts and the fundic glands adjacent to the anastomosis. These glands became large with time, resulting in formation of cystically dilated glands. These gland cells were partially stained with GOS, and then they retained a proliferative activity. These changes seemed to resemble "gastritis cystica profunda" in human remnant stomachs. At 50 and 80 weeks, adenocarcinomas were observed in 4 of 10 rats (40.0%) and in 16 of 21 rats (76.2%), respectively. We have noted that the early change of cystic proliferation of mucous glands resembled the so-called "ulcer associated cell lineage (UACL)" described by others, but our characteristic finding was not only pyloric but also foveolar metaplasia. This pyloric-foveolar metaplasia subsequently led to development of glands with intestinal-type goblet cells, which looked like incomplete intestinal metaplasia. This sequence was different from UACL, and very recently, we proposed a concept of "gut regenerative cell lineage (GRCL); from pyloric-foveolar to with goblet cell metaplasia in regeneration," common to all parts of the gut, and the stump cancer appeared to arise from GRCL.

Abstract
BACKGROUND AND AIMS Flow across the esophagogastric junction (EGJ) is strongly related to opening dimensions. This study aimed to determine whether opening of the relaxed EGJ was altered in patients with gastroesophageal reflux disease (GERD). METHODS Seven normal subjects (NL), 9 GERD patients without hiatus hernia (NHH), and 7 with hiatus hernia (HH) were studied. Cross-sectional area (CSA) of the relaxed EGJ was measured during low-pressure distention using a modified barostat technique that resulted in filling a compliant bag straddling the EGJ with renograffin to the set pressure. Swallows were imaged fluoroscopically at distensive pressures of 2-12 mm Hg. The diameter of the narrowest point of the EGJ in PA and lateral projections was measured from digitized images. CSA was determined as a function of intrabag pressure. RESULTS The minimal EGJ opening aperture occurred at the diaphragmatic hiatus in all subjects. At pressures </=0 mm Hg, EGJ opening was observed only in HH patients, making it plausible for these patients to reflux during deglutitive relaxation. At pressures >0 mm Hg, there were significant increases in EGJ CSA both for HH and NHH compared with NL (P < 0.001) and for HH compared with NHH (P < 0.005). This difference may explain the diminished air/water discrimination seen during transient lower esophageal sphincter (LES) relaxation-associated reflux in GERD patients. CONCLUSIONS Anatomic degradation of the EGJ distinguishes GERD patients from normal subjects, and these changes may impact on both the observed mechanisms of reflux and the constituents of reflux during transient LES relaxation. Therapy focused on EGJ compliance may benefit GERD patients.

Abstract
OBJECTIVE Our objective was to determine the relationship between reflux of duodenogastric contents with different degrees of esophagitis, and its levels and activity, with regard to the severity of esophagitis-induced duodenogastroesophageal reflux disease (DGERD). MATERIAL AND METHODS Our study design was prospective, transversal, descriptive, observational, and open. We took samples of gastric and esophageal juices from patients with a diagnosis of gastroesophageal reflux disease (GERD) and esophagitis during the period from March to August 2002. Sample material was placed in black rubber-covered assay tubes to prevent bilirubin degradation. In our Unit's central laboratory, these samples were centrifuged for 30 min, the dissolved material separated, and a reactive strip was introduced to measure the amount of bile pigment. Endoscopic study reports were provided by this Department on terminating the procedure. Univariate analysis was used to obtain results. RESULTS In 60% of cases, the esophageal liquid was positive for total bilirubin; 40% presented stage II esophagitis, 27% chronic esophagitis, and 27%, stage I esophagitis. Specific quantifications of total bilirubin at different stages of esophagitis demonstrated in stage II 50% with levels of 0.1-1, 33% with a level of 2-3, in cases of chronic esophagitis 75% with levels of 0.1-1, and with stage I esophagitis, 25% with levels of 2-3 mg/dl. Measurement of gastric pH showed 18 (69%) <3 and esophageal pH of 20 (67%) > 4, with 10 (33%) referring occasional or asymptomatic dyspepsia. We determined presence of duodenal elements in esophagus by means of quantification of total bilirubin in 60% of patients, observing greatest frequency of stage II esophagitis. Low but continuous levels of duodenal, principally biliary, elements continued in patients with DGERD, producing greatest damage in esophageal mucosa.

Abstract
BACKGROUND To elucidate the histogenesis of Barrett's esophagus and esophageal adenocarcinoma, we designed a duodeno-gastric reflux model in which normal stomach function and normal nutritional status are retained. METHODS Male Wistar rats were used in the experiment. The esophago-gastric junction was side-to-side anastomosed to a loop of jejunum about 3 cm distal to Treitz's ligament. The animals were not exposed to any known carcinogens during the experiment. Sequential morphological changes were studied for up to 50 weeks after surgery. Serial sections were made and stained with hematoxylin and eosin (H&E). In addition, immunohistochemical staining for bromodeoxyuridine (BrdU) was performed along with histochemical staining for mucins using paradoxical concanavalin A (ConA), galactose oxidase Schiff (GOS), and high-iron diamine-alcian blue (HID-AB). RESULTS Severe esophagitis with squamous cell hyperplasia was noted in all animals after surgery. At week 20 after surgery, glandular metaplastic cells positive for ConA first appeared within the basal cell layer of esophageal squamous cell epithelium, and then GOS-positive cells and HID-AB goblet cells appeared. This is a characteristic of the specialized columnar epithelium of Barrett's esophagus. We detected esophageal adenocarcinomas in 1 out of 8 subjects at week 40 and in 3 out of 8 subjects at week 50 after surgery. CONCLUSIONS Reflux of duodenal contents causes specialized columnar epithelium of Barrett's esophagus and esophageal adenocarcinoma. As part of the sequence of events leading to the development of Barrett's esophagus, pyloric-foveolar metaplasia was observed followed by the appearance of intestinal goblet cells. The pyloric-foveolar metaplasia appears to be associated with chronic mucosal damage and regeneration. This multiplastic cell lineage is referred to as 'gut-regenerative cell lineage' (GRCL).

Abstract
BACKGROUND Pylorus preservation has been proposed to reduce the disturbance in gastric emptying following gastrectomy but little is known about the role of the pylorus regarding motility patterns and alkaline reflux. AIMS To assess the motility patterns and alkaline reflux following pylorus preservation after complete gastrectomy and jejunal interposition in the pig. METHODS Motility patterns and alkaline reflux were studied in 12 conscious pigs before and after gastrectomy and jejunal interposition with preservation of the pylorus and a 1 cm antral ring (PYL+) or excised pylorus (PYL-) 6 and 14 weeks postoperatively. Gastroduodenal motility was investigated by manometry after fasting and fed, respectively and alkaline reflux by a fiberoptic system for detecting bilirubin. RESULTS The number of propagated phase-III activities of the jejunal interponat to the duodenum and propagating velocity were lower in the PYL+ group after 6 weeks (p < 0.05) but higher after 14 weeks (p < 0.05) compared to the PYL- group. In the PYL+ the number of intrapyloric pressure waves (IPPWs) was lower after 6 weeks (p < 0.05) but higher after 14 weeks (p < 0.05) in comparison to preoperative controls. Alkaline reflux was significantly higher in the PYL- group than in the PYL+ group throughout the time observed. CONCLUSIONS Pyloric function shows a delay after 6 weeks but restores within 14 weeks postoperatively. Pylorus preservation was associated with a significant decrease of alkaline reflux compared to PYL- in this setting.

Abstract
Results of examination of patients suffering from cholecystitis combined with duodenal ulcerative disease and accompanying duodenogastric reflux are presented. The comparison of acidifiable gastric function state in patients suffering from cholelithiasis combined with duodenal ulcerative disease and patients with only cholecystitis or duodenal ulcerative disease was performed. Intragastric pH-metry allows not only to study acidifiable gastric function but also to reveal functional disorders like duodenogastric reflux. Expressed and resistant duodenogastric reflux can result in structural modification of gastric mucosa.

Abstract
BACKGROUND The role of reflux of duodenal contents in gastroesophageal reflux in Japanese patients, which may be different from that in Western patients, was studied. METHODS Intraesophageal pH and the bilirubin concentration were monitored, using the Bilitec 2000, in 43 patients with reflux symptoms and 10 normal volunteers. The percentage of the time that spectrophotometric absorbance was 0.15 or more and pH was less than 4.0 was defined as the holding times (HTs) of bilirubin and acid, respectively. Severity of esophagitis was classified using the Savary-Miller (S-M) classification. RESULTS Esophagitis was present in 37 patients; 5, 10, 13, and 9 patients had S-M grades 1, 2, 3, and 4, respectively. Both HTs in the volunteers were less than 5%. Bilirubin HT was more than 5% in 3 of the 6 patients without esophagitis, but the acid HT was less than 5% in these 6 patients. Acid HT was less than 5% in 4, 2, 2, and 2 patients with S-M grades 1, 2, 3, and 4, respectively. Bilirubin HT was less than 5% in 1 patient with S-M grade 2 esophagitis. Bilirubin HT in patients with S-M grades 3 and 4 esophagitis (50.9 +/- 5.8%) was higher than that in grades 1 and 2 (14.9 +/- 2.9%) (P < 0.0001), but this was not so for acid HT. In 32 patients, bilirubin HT exceeded acid HT. Bilirubin HT did not correlate with acid HT. CONCLUSIONS Duodenogastroesophageal reflux occurred independently of and exceeded acid reflux. The amount of duodenogastroesophageal reflux correlated with the severity of esophagitis.

Abstract
BACKGROUND It has been claimed that the combination of bile and hydrochloride acid (HCl) has a noxious effect on intestinal mucosa. The aim was to study the reliability of the Bilitec 2001 method inmonitoring the presence of bile in repeated tests and at different pH and water dilutions. METHODS 24-h esophageal pH and gastric Bilitec monitoring were performed twice with an interval of 6 weeks in 23 patients with symptomatic gastroesophageal reflux (GER). In vitro tests of pH and Bilitec recordings were peformed with different mixtures of bile, HCl and water. RESULTS Gastric bile was present in 37% of the recording time, 28% during day time and 47% during nights. No significant difference was found between the two test occasions. The maximum bile concentration in the stomach was significantly lower in patients with severe pathological GER than in those with normal GER. When concentrated bile was diluted with the same volume of HCl, the pH level fell below 4. The maximum absorption limit with Bilitec in concentrated bile was gradually reduced with decreasing pH. The Bilitec technique recorded the presence of bile even at a pH of 1.4, but not if the bile was diluted with water at a ratio of 1:100 or more. CONCLUSIONS Bilitec gastric recordings show the same clinical result when repeated under standardized conditions. The Bilitec technique is not reliable for monitoring the amount and concentration of bile in the stomach. Bile reflux cannot be monitored with the pH recording technique.

Abstract
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.

Abstract
BACKGROUND Previous studies present conflicting results regarding relationship between gastric emptying and gastro-oesophageal reflux disease. Reflux of duodenal content to oesophagus is generally considered to be associated with more severe disease. AIM To assess presence of a gastric emptying disorder in persons with reflux of duodenal contents to oesophagus and to identify any correlation with gastric emptying and oesophageal motility. METHODOLOGY A total of 15 subjects with (B+) and 15 subjects without (B-) bile reflux to oesophagus determined by 24-hour bilirubin monitoring were studied with scintigraphic solid gastric emptying and 24-hour oesophageal manometry. RESULTS There was no difference in lag phase [median 23.7 (range 10.8-44.0) vs 24.6 (8.1-40.1) min], half emptying time [74.6 (48.0-93.6) vs 82.8 (54.4-153.9) min] or emptying rate [0.89 (0.59-1.34) vs 0.83 (0.36-1. 15)%/min] for B- and B+ subjects, respectively. In addition, there was no difference in emptying rate of gastric fundus between B- and B+ subjects. Subjects with bile reflux had less effective oesophageal contractions of oesophageal body [9.4(3.3-37)%] compared to subjects without bile reflux [32(19-47)%, p = 0.002]. However, there was no correlation between oesophageal motility and gastric emptying. CONCLUSION Results suggest that a gastric emptying disorder is a less likely contributing cause of bile reflux to the oesophagus, but bile reflux is associated with less effective oesophageal motility.

Abstract
The aim of the study was estimation of the relation between the gallbladder (GB) motility function and the presence and quantity of enterogastric reflux (EGR). We investigated 172 patients with: physiological GB function (filling and emptying)(FGB), impaired GB function (prolonged filling and ejection fraction < 45%) and afunctional gallbladder (AGB)(without visualization). The study was performed during 90 min (1 f/min) after i.v. application of 185 MB 99mTc-dietil IDA. After 30 min. test meal was given while at the end stomach was marked. According to the parameters from time activity curves over stomach and hepatobiliary system, the index of ERG was calculated, while GB filling and ejection fraction were estimated from the GB time/activity curve. We can conclude that EGR occurs more frequently in the patients with afunctional GB in comparison to those with functional and decreased motor function. Also, EGR quantity is in correlation with the impairment of the GB function.

Abstract
For over a century duodenogastric reflux (DGR) has been considered the main cause of the primary or secondary alkaline gastritis. In the first case it occurred in patients who had not been operated earlier, in the latter one in those after surgery of stomach, duodenum, gallbladder and bile ducts. Since first time many reports of clinical and experimental studies have demonstrated destructive effect of pancreatic enzymes, bile acids and their by-products on stomach mucose producing in consequence non-specific histologic lesions. It has been also observed that duodenogastric reflux plays the basic role in the patho-genesis of gastritis and other GI tract diseases (gastric ulcer, reflux oesophagitis, progressing metaplasia or oesophageal and gastric cancer). As far as diagnosing of alkaline gastritis requires histologic confirmation, duodenogastric reflux brings many more problems. However, the progress in medicine and technology allow direct measurement of quality and quantity of this reflux.

Abstract
OBJECTIVE To develop a non-invasive method for evaluating gastric emptying and duodenogastric reflux stroke volumes using three-dimensional (3D) guided digital color Doppler imaging. METHODS The technique involved color Doppler digital images of transpyloric flow in which the 3D position and orientation of the images were known by using a magnetic location system. RESULTS In vitro, the system was found to slightly underestimate the reference flow (by average 8.8%). In vivo (five volunteers), stroke volume of gastric emptying episodes lasted on average only 0.69 s with a volume on average of 4.3 ml (range 1.1-7.4 ml), and duodenogastric reflux episodes on average 1.4 s with a volume of 8.3 ml (range 1.3-14.1 ml). CONCLUSION With the appropriate instrument settings, orientation determined color Doppler can be used for stroke volume quantification of gastric emptying and duodenogastric reflux episodes.
