Abstract
PURPOSE We examined the clinical significance of duodenogastric regurgitation (DGR) as a late complication in the long-term follow-up after hepaticoduodenostomy (HD) as a reconstruction surgery for congenital biliary dilatation (CBD). METHODS Seventeen patients with CBD were retrospectively analyzed for late complications (mean follow-up, 16.8 years). All patients had undergone total resection of the extrahepatic bile duct followed by HD. DGR was identified using endoscopic examination, intraluminal bile monitoring, and liver scanning. RESULTS DGR was found in all 17 patients by endoscopic examination and intraluminal bile monitoring. Fourteen of the 17 (82.4%) patients with DGR had experienced abdominal symptoms since a mean of 6.9 years postoperatively. Liver scanning also revealed apparent DGR in all 14 symptomatic patients. We converted 7 of the 14 patients to hepaticojejunostomy reconstruction at a mean of 13.0 years after the initial excisional surgery. Their symptoms were completely relieved postoperatively. CONCLUSIONS DGR is an important complication after HD. Examination of patients for the development of DGR is an essential part of long-term follow-up in patients with CBD who have undergone HD as a reconstruction surgery. Conversion surgery is recommended in patients with DGR accompanied by long-term abdominal symptoms. LEVELS OF EVIDENCE Level IV.

Abstract
Endoscopy plays an important role in the diagnosis and treatment of postoperative complications of gastric cancer. Endoscopic intervention can avoid the second operation and has attracted wide attention. Early gastric anastomotic bleeding after gastrectomy is the most common. With the development of technology, emergency endoscopy and endoscopic hemostasis provide a new treatment approach. According to the specific circumstances, endoscopists can choose metal clamp to stop bleeding, electrocoagulation hemostasis, local injection of epinephrine or sclerotherapy agents, and spraying specific hemostatic agents. Anastomotic fistula is a serious postoperative complication. In addition to endoscopically placing the small intestine nutrition tube for early enteral nutrition support treatment, endoscopic treatment, including stent, metal clip, OTSC, and Over-stitch suture system, can be chosen to close fistula. For anastomotic obstruction or stricture, endoscopic balloon or probe expansion and stent placement can be chosen. For esophageal anastomotic intractable obstruction after gastroesophageal surgery, radial incision of obstruction by the hook knife or IT knife, a new method named ERI, is a good choice. Bile leakage caused by bile duct injury can be treated by placing the stent or nasal bile duct. In addition, endoscopic methods are widely used as follows: abdominal abscess can be treated by the direct intervention under endoscopy; adhesive ileus can be treated by placing the catheter under the guidance of endoscopy to attract pressure; alkaline reflux gastritis can be rapidly diagnosed by endoscopy; gastric outlet obstruction mainly caused by cancer recurrence can be relieved by metal stent placement and the combination of endoscopy and X-ray can increase success rate; pyloric dysfunction and spasm caused by the vagus nerve injury during proximal gastrectomy can be treated by endoscopic pyloromyotomy, a new method named G-POEM, and the short-term outcomes are significant. Endoscopic submucosal dissection (ESD) allows complete resection of residual gastric precancerous lesions, however it should be performed by the experienced endoscopists.

Abstract
BACKGROUND Cholecystectomy alters bile release dynamics from pulsatile meal-stimulated to continuous, and results in retrograde duodeno-gastric bile reflux (DGR). Bile is implicated in mucosal injury after gastric surgery, but whether cholecystectomy causes esophagogastric mucosal inflammation, therefore increasing the risk of metaplasia, is unclear. STUDY DESIGN This study examined whether cholecystectomy-induced DGR promotes chronic inflammatory mucosal changes of the stomach and/or the esophagogastric junction (EGJ). Four groups of patients were studied and compared with controls. A group of patients was studied before and 1 year after cholecystectomy; 2 further groups were studied long-term post-cholecystectomy (LTPC) at 5 to 10 years and 10 to 20 years. All underwent abdominal ultrasound and upper gastrointestinal endoscopy with gastric antral and EGJ biopsies, noting the presence of gastric bile pooling. Biopsy specimens were stained for Ki67 and p53 overexpression, and the bile reflux index (BRI) was calculated. RESULTS At endoscopy, bile pooling was observed in 9 of 26 (34.6%) controls, in 8 of 25 (32%) patients pre-cholecystectomy, in 15 of 25 (60%) 1 year post-cholecystectomy patients (p = 0.047), and 23 of 29 (79.3%) LTPC patients (p = 0.001). Bile reflux index positivity at the EGJ increased from 19% of controls through 41% of LTPC patients (p = 0.032). Ki67 was overexpressed at the EGJ in 19% of controls, but in 62% of LTPC patients (p = 0.044); p53 was overexpressed at the EGJ in 19% of controls compared with 66% of LTPC patients (p = 0.001). CONCLUSIONS Duodeno-gastric bile reflux was more common in patients with gallstones than in controls, and its incidence doubled after cholecystectomy. This was associated with inflammatory changes in the gastric antrum and the EGJ, evident in most LTPC patients. Ki67 and p53 overexpression at the EGJ suggests cellular damage attributable to chronic bile exposure post-cholecystectomy, increasing the likelihood of dysplasia. Further studies are required to determine whether DGR-mediated esophageal mucosal injury is reversible or avoidable, and whether surveillance endoscopy is indicated after cholecystectomy.

Abstract
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. Although eradication of Helicobacter pylori (H. pylori) in remnant stomach is promising, it is still uncertain whether it can reduce the risk of carcinogenesis. Periodic endoscopic surveillance after DG was reported useful in detecting RGC at an early stage, which offers a chance to undergo minimally invasive endoscopic treatment or laparoscopic surgery and leads to an improved prognosis in RGC patients. Future challenges may be expected to elucidate the benefit of eradication of H. pylori in the remnant stomach if it could reduce the risk for RGC, to build an optimal endoscopic surveillance strategy after DG by stratifying the risk for development of RGC, and to develop a specific staging system for RGC for the standardization of the treatment by prospecting the prognosis.

Abstract
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.

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
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
UNLABELLED Many hypotheses affirm that postcholecystectomy syndrome is caused by alterations in bile flow due to the loss of the reservoir function of the gallbladder. We aimed to establish the relationship between postcholecystectomy symptoms and bile reflux. MATERIAL AND METHOD Thirty patients with gallstones were included in the study. All patients underwent combined ambulatory pH and bile monitoring (Bilitec). Three months after cholecystectomy, the tests were repeated. RESULTS Before surgery, the median (interquartile range) total time pH < 4 was 2.8% (0.2-14%) and bilirubin absorbance > 0.14 was 4.1% (0-17%). After cholecystectomy, the median total time pH < 4 was 3.7% (1.5 %-11.4%) and bilirubin absorbance > 0 14 was 13.25% (5.30%-26.5%). The correlation between total time pH < 4 and total time bilirubin absorbance > 0.14 for all patients was good: r = 0.55, p < 0.001. Before surgery 65.03% of symptoms were not associated with neither acid nor bile reflux and postcholecystectomy 37.87% of symptoms were associated with bile reflux and 36.95% without any reflux. Cholecystectomy determines increased biliary reflux compared to the patients with gallstones. Related to gallstones, after cholecystectomy dyspeptic complains are more often related to bile reflux. CONCLUSION Although cholecystectomy itself does cause increased biliary reflux, in most patients with significant duodenogastric reflux symptoms were not correlated with biliary reflux.

Abstract
BACKGROUND To assess the effect of Roux-en-Y gastric bypass (RYGB) at a tertiary referral Center of Excellence for bariatric surgery on the length and presence of dysplasia in morbidly obese patients with Barrett's esophagus (BE). Esophageal reflux of gastroduodenal contents (acid, bile) contributes to the development of BE and progression in the dysplasia-carcinoma sequence. Obese patients have a high prevalence of gastroesophageal reflux and might be at an increased risk of developing BE and esophageal adenocarcinoma. The effect of eliminating duodenogastroesophageal reflux on BE is not known. METHODS We performed a retrospective review of all patients with pre-existing, biopsy-proven, long-segment (>3 cm) BE undergoing RYGB at our institution. Only patients with >1 year of endoscopic, biopsy-controlled follow-up (mean 34 mo) were included. RESULTS Five patients (3 men and 2 women) were identified. The mean +/- standard error of the mean preoperative length of BE was 6 +/- 2 cm; 2 patients had low-grade dysplasia and 1 indeterminate dysplasia. At the postoperative follow-up (>1 yr) examinations, the length of BE had decreased in 4 patients; the overall length was 2 +/- 1 cm; and only 1 patient had dysplasia. All patients experienced a decrease in the length of BE (n = 4), complete disappearance of BE (n = 2), or improvement in the degree of dysplasia (n = 3). The body mass index had decreased from 43 +/- 4 kg/m(2) to 33 +/- 3 kg/m(2), and all experienced subjective improvement in reflux symptoms postoperatively. RYGB resulted in complete or partial regression of BE in 4 of 5 patients and improvement in reflux symptoms in all. CONCLUSION Our results suggest that RYGB might be the procedure of choice in morbidly obese patients with BE requiring surgical treatment for gastroesophageal reflux disease.

Abstract
BACKGROUND/AIMS Persistence of dyspeptic symptoms after choledochoduodenostomy (CDD) is common. There is evidence that at least some of these symptoms may be attributed to duodenogastric reflux (DGR). The aim of the study was to quantify DGR after CDD. METHODOLOGY A total of 6 patients who had undergone cholecystectomy with a standard side-to-end CDD for choledocholithiasis or Lemmel syndrome were studied by symptom evaluation, biliary scintigraphy and endoscopy at least 6 months after surgery. Duodenogastric reflux was quantified using continuous intravenous infusion of 99mTc-HIDA. RESULTS The incidence of DGR after CDD was 67% compared to healthy control. In the majority of the patients the DGR was mild to moderate, but not with the clinical symptoms. CONCLUSIONS 99mTc-HIDA scanning of the hepatobiliary system is a reasonable and reliable method for the quantitative evaluation of DGR. CDD is associated with a high incidence of DGR, but its occurrence does not produce significant clinical symptoms.

Abstract
The study was aimed at defining the informative value of dynamic hepatobiliary scintigraphy (HBSG) in the evaluation of duodenal reflux in patients with postgastrectomic disorders after reconstructive surgery. HBSG was performed in 23 patients. After intravenous injection of 99mTc bromeside in a dose of 74-80 MBq, the areas concerned were identified in the projection of the liver, gallbladder, hepaticocholedochus, duodenum, and stomach for 120 minutes with 60-min cholagogic breakfast. Histrograms were plotted in the activity-time coordinates; hepatic function, gallbladder contractility, and hepaticocholedochal patency were evaluated; the duodenal motor function index and the gastroduodenal reflux were estimated. HBSG is physiological, which makes it possible to reveal duodenal motor-and-evacuation disorders, to specify the reason for poor outcomes of gastrectomy, to objectively evaluate the severity of postgastrectomic disorders, and to determine further treatment policy for this difficult group of patients.

Abstract
Intragastric pH-metry and esophagogastroduodenoscopy has been performed in 64 patients with chemical burn of the esophagus. It has been revealed that 51.6% patients had hyperacidity, 25% - normacidity, and 23.4% - hypoacidity. Gastroesophageal reflux has been diagnosed in 50% patients according to pH-metry examination and in 80-100% patients according to esophagogastroduodenoscopy, duodenogastric reflux - in 25 and 34.4% cases, respectively. A direct correlation exists between gastroesophageal reflux and basal gastric acidity, severity of chemical burn of the esophagus. It is concluded that antisecretory therapy is mandatory in complex treatment of patients with chemical burn of the esophagus.

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.

AIM To study characteristics (other than duration) of duodenogastric reflux (DGR), correlations of secretory function and DGR characteristics with gastroduodenal disorders (ulcer, chronic hyperacid gastritis). MATERIAL AND METHODS A total of 110 patients were examined with 24-h pH-metry: 68 patients with duodenal ulcer (DU), 15 patients with gastric ulcer (GU), 27 patients with chronic hyperacid gastritis (CHG). Mean levels of pH and duration of hyperacidity in the body and an antral part of the stomach, duration of DGR, pH in the body and antral part of the stomach depending on DGR severity were studied. RESULTS DGR was registered almost in all the patients with DU, GU and CHG. Groups of the patients differed by duration and height" of the DGR. CONCLUSION Patients with DU are characterized by low refluxes which do not reach gastric body.

Abstract
Duodenogastric reflux (DGR) is a common sequel of subtotal esophagectomy and gastric pull-up, and it may contribute to mucosal changes of both the gastric conduit and the esophageal remnant. This study investigated the effect of the route of reconstruction on the DGR. 24-hour ambulatory bilirubin monitoring was performed on patients who underwent transhiatal subtotal esophagectomy and a gastric tube interposition either in the posterior mediastinum (PM group, n = 11), or in the retrosternal space (RS group, n = 8): A Control group of 8 healthy volunteers was also studied. The median percentage of reflux time, the median number of reflux episodes, and the median number of reflux episodes longer than 5 minutes, in PM versus RS groups, were 29.1% versus 0.15% (p < 0.001), 185 versus 8 (p = 0.002) and 10 versus 0 (p = 0.001), respectively. The values of the above variables in PM versus control groups were 29.1% versus 3.95% (p = 0.007), 185 versus 21 (p = 0.02), and 10 versus 2 (p = 0.009), respectively, whereas in RS versus control groups they were 0.15% versus 3.95% (p = 0.01), 8 versus 21 (p = 0.04), and 0 versus 2 (p = 0.05), respectively. Posterior mediastinal gastric interposition is associated with high reflux of duodenal contents, whereas retrosternal interposition minimizes the reflux at levels even lower than those of the healthy individuals. The latter type of reconstruction may be a good alternative from that perspective, especially in patients with long life expectancy.

Abstract
OBJECTIVE Patients who undergo esophagectomy with gastric tube reconstruction incur increased risk for acid reflux and duodenogastroesophageal reflux. Few postesophagectomy studies of gastroesophageal reflux disease have included simultaneous 24-h pH and bilirubin monitoring. The aim of this study is to evaluate acid reflux and duodenogastroesophageal reflux after esophagectomy with gastric tube reconstruction. METHODS Reflux symptom evaluation, endoscopy, and simultaneous 24-h pH and bilirubin monitoring in the cervical esophagus were performed in 25 patients who underwent Ivor Lewis esophagectomy, intrathoracic esophagogastrostomy, and digital dilation of the pyloric ring as treatment for esophageal cancer. RESULTS Reflux symptoms were severe, mild, and absent in 2, 7, and 16 patients, respectively. Reflux esophagitis and Barrett's esophagus was observed in 11 and 1 patients, respectively. Elevated acid reflux occurred in 7 patients (28%). Elevated duodenogastroesophageal reflux was recorded in 11 patients (44%). Reflux profile analysis identified three patterns: 4 subjects (16%) with both elevated acid reflux and duodenogastroesophageal reflux; 3 (12%) with only elevated acid reflux; and 7 (28%) with only elevated duodenogastroesophageal reflux. Of 7 patients with only elevated duodenogastroesophageal reflux, 4 developed reflux esophagitis. Although reflux symptoms did not correlate with endoscopic esophagitis, a significant correlation was observed between endoscopic esophagitis and acid reflux and/or duodenogastroesophageal reflux. CONCLUSIONS Reflux symptoms represented a poor indication of esophagitis in patients with esophagectomy and gastric tube reconstruction. Simultaneous 24-h pH and bilirubin monitoring can help in identifying patients at high risk for reflux esophagitis, as well as indicating the cause of esophagitis.

Abstract
Duodenogastric reflux (DGR) was assessed in patients surgically treated for choledochal cyst, with emphasis on two different biliary reconstruction methods: Roux-en-Y hepaticojejunostomy (HJ) and hepaticoduodenostomy (HD). Gastric bile monitoring with the Bilitec device revealed excessive DGR in patients in the HD group. Endoscopic findings demonstrated mild to moderate gastric mucosal erosion in patients after HD. In contrast, neither DGR nor gastritis was found in patients after HJ. This preliminary study suggests that HJ, rather than HD, should be recommended as a method of biliary reconstruction for pediatric patients with choledochal cyst. Careful observation of DGR should be continued in patients who have undergone HD.

Abstract
We reviewed our experience of Roux-en-Y hepaticojejunostomy (RYHJ) and hepaticoduodenostomy (HD) performed for the surgical repair of choledochal cyst (CC), with special emphasis on postoperative complications related to the type of biliary reconstruction performed. Eighty-six patients underwent primary cyst excision for CC from 1986 to 2002 at our institution. Forty-six cases with concurrent intrahepatic bile duct dilatation (IHBD) were excluded because HD was not used for biliary reconstruction if IHBD was present. Thus, 28 cases had RYHJ, and 12 had HD. Differences between the RYHJ and HD groups with respect to type of CC, age at cyst excision, and length of follow-up were not statistically significant. However, the incidences of postoperative complications related to biliary reconstruction, such as endoscopy-proven bilious gastritis due to duodenogastric bile reflux [4/12 (33.3%) of the HD group], and adhesive bowel obstruction/cholangitis [2/28 (7.1%) of the RYHJ group] were significantly different (p<.05). Our experience suggests that HD is not ideal for biliary reconstruction in CC because of a high incidence (33.3%) of complications due to duodenogastric bile reflux. Currently, RYHJ is our exclusive technique of choice for biliary reconstruction during the surgical repair of CC.

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
BACKGROUND/AIMS Many patients who undergo distal gastrectomy develop remnant gastritis. This report describes the correlation between remnant gastritis and the amount of duodenogastric reflux and looks at the relationship between Helicobacter pylori infection and duodenogastric reflux in remnant gastritis. METHODOLOGY Sixty-two patients who underwent curative distal gastrectomy for gastric cancer with radical lymphadenectomy were studied. The period of bile reflux (percent time) into the gastric remnant was measured with the Bilitec 2000 under standardized conditions. Remnant gastritis was semi-quantified using the neutrophil infiltration score based on the updated Sydney System, and the presence of H. pylori infection was determined 12 weeks after the surgery. RESULTS Overall, the correlation was not significant between the neutrophil infiltration score and the percent time (p=0.08). Similarly, the correlation was not significant in patients with H. pylori infection (p=0.30), but it was significant in patients without H. pylori infection (p=0.03). CONCLUSIONS Duodenogastric reflux after distal gastrectomy can cause remnant gastritis in patients without H. pylori infection. Reconstruction with biliary diversion is protective against the development of remnant gastritis.

Abstract
BACKGROUND Patients with cystic fibrosis (CF) have a high incidence of gastroesophageal reflux disease, but few cases of mucosal injury are reported. Duodenogastric reflux has not been studied in CF but has been suggested to have a pathogenic role in producing alkaline injury to the esophageal mucosa. The aim of this study was to analyze the presence of duodenogastric reflux in patients with CF. PATIENTS AND METHODS Ten patients with CF and 7 healthy volunteers participated in the study. Gastroduodenal manometry and intragastric perfusion were performed in all subjects. Gastric perfusate was analyzed for bilirubin and bile acids. Only patients and controls exhibiting normal migrating motor complexes were evaluated. RESULTS Eight patients with CF had normal motility recordings and had significantly higher gastric bilirubin levels compared with healthy subjects (P = 0.003). The bilirubin concentration was associated with bile acid regurgitation in five patients with CF. All bile acids were conjugated with a high glycine/taurine ratio and low levels of secondary bile acids. Small amounts of keto bile acids were found in two patients. CONCLUSION The patients with CF had an increased incidence of duodenogastric reflux compared with healthy subjects. The bile acid composition was typical for CF with low levels of secondary bile acids. Although high bile acid concentration was found in the duodenogastric reflux in most patients with CF, the less toxic profile of the bile acids might possibly contribute to the low frequency of Barrett's esophagus in CF.

Abstract
Primary chronic gastroduodenitis (PCGD) accounts for 60-85% of the diseases of the gastroduodenal zone. In our study 90 patients with PCGD were divided into three groups getting one of the following therapies: electric sleep, hofitol, electric sleep plus hofitol. The effects of the treatments were assessed with updated techniques including computed pH-metry. Hofitol showed a good effect on dyspepsia, enhanced the alkalizing ability of the duodenal bulb. Electric sleep relieved pain and asthenoneurotic syndromes, decreased high acidity of the gastric juice in the body of the stomach. Electric sleep in combination with hofitol normalized macroscopic picture of the upper gastrointestinal tract and corrected imbalanced immunity.

Abstract
UNLABELLED Primary duodenogastric reflux is a rare disorder in adults which has not yet been documented in children. Six young patients, aged 4.5 to 16.5 years (median 13.5 years) presented with atypical reflux symptoms persisting from 1 to 84 months (median 8 months) and unresponsive to classical antacid therapy. In all six patients, 24 h gastric bilimetry showed excessive bile exposures for absorbances ranging from 0.25 to 0.60. The fraction of time (supine period) above the 0.25 absorbance threshold ranged from 30% to 75% while the 95th percentile value for healthy adults is 31%. In all patients tested, hepato-iminodiacetic acid scintigraphy revealed the occurrence of a massive duodenogastric reflux and four out of five patients had an alkaline shift (fraction of time pH >8 on 24 h lower oesophageal pH monitoring) ranging from 4.2% to 20% (control values 0.0% to 2.9%). Endoscopic findings included abundant bilious gastric leak (6/6) and chronic prepyloric Helicobacter pylorinegative gastritis (2/6). Daily administration of cisapride, sucralfate with or without omeprazole resulted in an improvement of symptoms in five patients within 15 days. This treatment was ineffective in one patient who became symptom-free only after a surgical duodenal switch with fundoplication was performed. CONCLUSION primary duodenogastric reflux is a rare foregut disorder of unknown origin occurring in late childhood. If suspected, 24 h intragastric bilimetry appears to be a useful investigation to confirm the diagnosis.

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
BACKGROUND Persistence of dyspeptic symptoms after cholecystectomy or choledochoduodenostomy is common. There is -evidence that at least some of these symptoms may be attributed to duodenogastric reflux (DGR). The aim of the study was to quantify DGR before and after cholecystectomy, with or without choledochoduodenostomy, and endoscopic sphincterotomy for common bile duct stones, and to assess the effect of erythromycin on the increased DGR. METHODS Forty-seven patients before and after cholecystectomy, 26 after cholecystectomy and choledochoduodenostomy and nine after sphincterotomy had postprandial (300 mL of fresh milk, 4% fat) duodenogastric reflux measured by 99mTc-hepatic imino diacetic acid scintigraphy. Patients with a DGR index (DGRi) >20% were considered as having pathological DGR that justifies symptoms, and their DGRi was reassessed after administration of 200 mg of erythromycin intravenously. RESULTS Twenty-seven patients before cholecystectomy (57%) showed a normal DGRi <7%. In five cases DGRi was greater than 20%. After cholecystectomy, duodenogastric refluxes increased, so that only 16 patients (32%) showed a normal DGRi, while a DGRi >20% was observed in 10 cases. Only eight patients after cholecystectomy and choledochoduodenostomy (23%) presented with a DGRi within the normal range. The remaining 18 had a DGRi >7%. Five of them exhibited a DGRi >20%. Of the nine patients with sphincterotomy, three showed a DGRi >20%. Erythromycin almost completely normalized DGRi in all 18 patients with pathological DGR (P < 0.0001). CONCLUSIONS Duodenogastric reflux is common after biliary surgery, including endoscopic sphincterotomy. Erythromycin appears to decrease duodenogastric reflux to normal levels.

Abstract
Billroth I or II reconstruction after distal gastrectomy often is associated with inflammation in the gastric remnant. We sought to determine which reconstructive procedure was most effective in preventing such remnant gastritis. Patients undergoing curative distal gastrectomy for cancer ( n = 82) were classified as group A (Roux-en- Y, n = 22); group B (Billroth I, n = 40); or group C (Billroth II, n = 20). Interleukin (IL)-8 concentrations in gastric mucosa were measured 3 months after surgery. In the absence of Helicobacter pylori infection, IL-8 concentrations were 13, 56, and 87 pg/mg protein in groups A, B, and C, respectively ( p < 0.05). In the presence of H. pylori infection, IL-8 concentrations were 61, 161, and 234 pg/mg protein in groups A, B, and C ( p < 0.01). Roux-en- Y reconstruction is better able to prevent remnant gastritis than either the Billroth I or II procedure as judged from IL-8 concentrations in gastric remnant mucosa.

Abstract
Gastric stump carcinoma after gastric surgery for benign disease is now widely recognized as a distinct clinical entity. The stump carcinoma was often found to be localized to the anastomosis, known to be the site with severe duodenogastric reflux. For this reason, duodenogastric reflux, including the reflux of bile and pancreatic juice, after a Billroth II procedure for benign disease is frequently discussed as an important factor related to the development of stump carcinoma. Many experiments have implicated bile acids, the main component of the duodenal juice, in gastric carcinogenesis. In particular, rat models without the use of the carcinogen, N-methyl-N'-nitro-N-nitrosoguanidine (MNNG), showed adenocarcinoma in the remnant stomach that was related to the severity of duodenogastric reflux. However, human data are, inevitably, much less consistent. Whether the incidence of stump carcinoma is higher than that of gastric carcinoma in general is still controversial. Concerning the histogenesis of stump carcinoma after benign disease, a relationship between gastritis cystica polyposa (GCP) and gastric type adenocarcinoma has been suggested. Recently, the population at risk of gastric stump carcinoma for benign disease has been diminishing significantly, and the incidence of gastric stump carcinoma after surgery for malignant disease has been increasing. The influence of duodenogastric reflux in the gastric remnant after malignant disease may differ from its influence in the gastric remnant after benign disease. Further clinical study is needed to elucidate the pathogenetic factors involved in gastric stump carcinoma.

Abstract
BACKGROUND It has been suggested that symptoms from bile reflux gastritis are related to the frequency and degree of enterogastric reflux (EGR). METHODS Patients with history of upper gastrointestinal surgery or cholecystectomy as well as control patients were studied. Presence of EGR, degree of EGR, and gastric bile emptying time were assessed and quantified via 99mTC scintillation imaging and then compared between symptomatic and asymptomatic patients. RESULTS Patients with vagotomy and pyloroplasty, Billroth I, Billroth II, and cholecystectomy demonstrated statistically higher degrees of EGR compared with controls. Although asymptomatic and symptomatic patients with a history of upper gastrointestinal or biliary surgery demonstrated no statistically significant differences between incidence of EGR and degree of EGR, there was a statistically significant difference in gastric emptying time. CONCLUSIONS Delayed gastric emptying time, not frequency or extent of EGR, was associated with the symptoms of bile reflux in patients who had previous upper gastrointestinal or biliary operations.

Abstract
OBJECTIVES To establish a relationship between hyperemesis gravidarum (HG) and Helicobacter pylori (H. Pylori) infection by histologic testing. METHODS Twenty patients with severe HG (Group I) and 10 volunteer pregnant women without gastric complaints (Group II) were included in the study. Endoscopic evaluations were done in both groups and biopsies were obtained from the antrum and corpus for the histopathologic diagnosis of H. pylori. The groups were compared with the chi(2)-test and Fisher's exact test where appropriate. RESULTS H. pylori was diagnosed in 19 (95%) of 20 patients in Group I and 5 (50%) of 10 patients in group II. H. pylori densities in the antrum and corpus were higher in Group I and the differences between the two groups were statistically significant. The biopsy specimens revealed significant inflammation and H. pylori activation processes in patients with HG, and in 18 of 19 patients inflammation scores were greater than +2 on the scale. Pangastritis was demonstrated by endoscopic examination in 17 of 20 patients with HG. Enterogastric reflux was also diagnosed in 10 patients. In the control group, three patients had antral gastritis. CONCLUSIONS We suggest that in patients with intractable nausea and vomiting during pregnancy, pangastritis and enterogastric reflux are the main endoscopic findings and that these findings are closely associated with H. pylori infection, which can be diagnosed histologically. The degree of gastric complaints may be associated with the density of H. pylori infection.

Abstract
The complex approach to therapy of pylorobulbar ulcers combined with duodenogastral reflux was developed and introduced into the clinical practice. The treatment stipulates the elements of functional surgery and eradicative antiinflammatory and antisecretory therapy. The use of this complex method permits to obtain the good results providing the food passage close to physiologic one, to prevent the ulcer recurrence, development of gastric mucosa pathology caused by duodenogastral reflux and persistence of Helicobacter pylori infection. As the result the patients' life quality significantly improves.

Abstract
BACKGROUND AND STUDY AIMS The main complication associated with biliary stenting is stent occlusion. This study tested the hypothesis that bilioduodenal reflux may play a crucial role in stent clogging. PATIENTS AND METHODS Plastic stents in 100 consecutive patients with various biliary disorders were investigated macroscopically and cytologically. RESULTS In 37 patients with elective stent extraction, the only risk factor for stent occlusion was the duration of stenting. Plant material was found as a consequence of duodenobiliary reflux in 38 of the 89 stents with any stent content. In patients who had two stents, the stent content was identical in eight of 14 cases. CONCLUSIONS In addition to other mechanisms of biliary stent occlusion, duodenobiliary reflux appears to play an important role. A stent design capable of at least partly preventing this type of reflux might be of clinical benefit.

Abstract
BACKGROUND Duodenogastric reflux has been implicated in the pathogenesis of gastric ulcer and gastritis. Duodenogastric reflux after cholecystectomy is also a possible cause of post-cholecystectomy syndrome. AIM To investigate the role of antroduodenal motor function in increased duodenogastric reflux following cholecystectomy and the effect of trimebutine maleate (trimebutine) on the duodenogastric reflux in conscious dogs. METHODS Antropyloric and duodenal motility and bile acids content in the gastric juice were measured for 3 h during the inter-digestive state in dogs with or without cholecystectomy. RESULTS Bile acids content in the gastric juice of cholecystectomized dogs was significantly higher than that of non-cholecystectomized dogs. The frequency of pyloric relaxation during phase II of the migrating motor complex was significantly increased following cholecystectomy. Intravenous infusion of trimebutine inhibited both the increased duodenogastric reflux and the frequency of pyloric relaxation in the cholecystectomized dog. CONCLUSION Duodenogastric reflux and frequency of pyloric relaxations were increased in cholecystectomized dogs and trimebutine suppressed both of them. These findings suggest that the increased frequency of pyloric relaxation contributes to the duodenogastric reflux following cholecystectomy.

Abstract
BACKGROUND Duodeno gastric reflux (DGR) is still a not well-defined condition, even though it has been the subject of different studies for many years. METHODS The authors examine its relation with gallstones before and after the surgical removal of the gallbladder. After examining various study techniques, they present their experience of DRG. In this work the methodology used in a group of 40 patients suffering from gallstones and operated by laparotomic cholecystectomy is presented. All patients have been subjected to a clinical questionnaire in order to evaluate their symptoms, before and after cholecystectomy, and at the same time they have been subjected to an endoscopic exam. It s not easy to comment the RESULTS. RESULTS Actually, of 32 patients (80%) showing DGR symptoms before surgical treatment, 20 showed their persistence, worsening, or the appearance of new symptoms after cholecystectomy, while 12 were completely asymptomatic. Of 8 patients with no symptoms before cholecystectomy, 3 developed a typical DGR symptomatology while 5 were asymptomatic. CONCLUSIONS So 57% of patients were DGR symptomatic after surgical treatment. The compromised function of cholecystitis with calculi, antrum-pyloric-duodenal motility, continuous bile flux in the duodenum, surgical trauma all interact in determining DGR.

Abstract
BACKGROUND The authors analyse gastroduodenal reflux (GDR) in the light of the progress made over the past ten years. The good results achieved using mini-invasive techniques in cholecystectomy prompted the authors to compare laparotomic and laparoscopic cholecystectomy in order to evaluate the influence of both techniques in determining GDR and clinical symptoms. METHODS Symptoms were evaluated before and after surgery in 30 patients operated using a laparotomic technique and in 30 patients operated using a laparoscopic technique. Two groups of 10 patients, operated respectively using laparotomic and laparoscopic techniques, were studied both clinically and endoscopically before and after surgery. RESULTS The analysis of the results shows a lower incidence of GDR and typical symptoms of GDR in patients undergoing laparoscopic surgery. The rationale underlying the lower incidence of GDR and its symptoms in these patients compared to the more conventional group is not completely clear. CONCLUSIONS These results may be influenced by reduced surgical trauma and the careful selection of case or the laparoscopic technique, hence the exclusion of cases complicated by severe cholecystitis.

Abstract
BACKGROUND A widely used rat model for reflux-induced esophageal adenocarcinoma in the absence of carcinogens involves induction of duodenoesophageal reflux by performance of esophagoduodenostomy. The aim of this study was to test the hypothesis that acid reflux reduces the incidence of adenocarcinoma in this animal model. METHODS One hundred ninety 8-week-old male Sprague-Dawley rats were studied. The animals were randomly divided into four groups with a different type of reflux established in each group. Group 1 had an esophagoduodenostomy for duodenogastroesophageal reflux (n = 59), group 2 had an esophagoduodenostomy and a total gastrectomy for duodenoesophageal reflux (n = 54), group 3 had an esophagoduodenostomy and a total gastrectomy with acid supplementation with acidified water to control for the effect of the gastrectomy (n = 50), and group 4 had a total gastrectomy with Roux-en-Y reconstruction to eliminate all reflux (n = 25). One hundred eighty-eight surviving animals were sacrificed at 36 weeks of age and the resected esophagi were examined. RESULTS All animals except the no reflux control group had severe reflux esophagitis. The frequency of tumor development was similar in all study groups. All of the tumors were well-differentiated adenocarcinomas that were located on the external surface of the bowel either at or immediately distal to the esophagoenteric anastomosis. The tumors appeared to arise from the submucosa and did not involve the overlying mucosa. There was no definite evidence of columnar lining of the esophagus but an admixture of squamous and columnar epithelium was found microscopically in all groups. This finding was unrelated to the presence and composition of reflux. CONCLUSIONS Adenocarcinomas in this animal model are not reflux-induced and do not arise from the mucosa. Despite previous reports to the contrary, we suggest that this model may not be valid for the study of reflux-induced esophageal adenocarcinoma.

Abstract
BACKGROUND & AIMS Esophagitis has been reported to be the most frequent cause of upper gastrointestinal bleeding in intensive care patients. The mechanisms causing esophagitis are unclear. The aim of this study was to measure esophageal acid and bile reflux and to examine the relationship between reflux and mucosal injury in mechanically ventilated patients. METHODS Twenty-five critically ill, mechanically ventilated patients with nasogastric tubes were prospectively included for 24-hour esophageal pH and duodenogastroesophageal bile reflux studies (Bilitec 2000 system). All patients received acid-suppressive therapy for stress ulcer prophylaxis with ranitidine. On the day before the study, patients underwent esophageal endoscopy to determine the presence or absence of esophagitis. RESULTS After approximately 5 days of mechanical ventilation, 12 patients (48%) had erosive esophagitis, 2 patients had pathological acid reflux, and 12 patients had pathological bile reflux. The presence of esophagitis was significantly associated with pathological bile reflux (P = 0.017, Fisher exact test). The severity of esophagitis was significantly correlated with the volume of gastric residual volume and with increasing times of bile reflux. The latter was significantly correlated with the number of organ failures. CONCLUSIONS Despite acid-suppressive therapy, esophagitis is a frequent finding in critically ill patients after less than a week of mechanical ventilation. In these patients, besides mechanical irritation by the nasogastric tube, chemical injury caused by duodenogastroesophageal reflux seems to have a major role in the pathogenesis of esophageal mucosal lesions.

Abstract
OBJECTIVE In order to prevent gastric microbial overgrowth, which may complicate nasogastric feeding, administration of nutrients more distally into the gut has been advocated in intensive care patients, as it offers the advantage of keeping the stomach empty and acid. In this study, we assessed the impact of jejunal feeding upon gastic pH in a group of mechanically ventilated, critically ill patients, with special focus on duodenogastric reflux as a possible cause of gastric alkalinization during jejunal nutrition. DESIGN Prospective experimental study. SETTING Multidisciplinary intensive care unit of a university hospital. PATIENTS AND METHODS Gastric pH was recorded by continuous pHmetry over a 4-h period of fasting followed by a 4-h period of nasojejunal feeding at 100 kcal/h in 21 mechanically ventilated, critically ill patients. To determine the contribution of duodenogastric reflux to modifications of gastric acidity, the diet was traced with [(111)In] DTPA (pentetic acid) in 11 of these 21 patients; gastric contents were aspirated every 30 min, then analysed for measurement of radioactivity, glucose, and bile acid concentration. MEASUREMENTS AND RESULTS Median intragastric pH increased slightly from 1.59 (1.20-2.73; interquartile range) (fasting) to 2.33 (1.65-4.64) (feeding) (p = 0.013), and the length of time that the pH was 4 or above increased from 1 (0-24) to 9 (0-142) min (p = 0.026). The variability of pH values and the number of acute alkalinization episodes did not change between the two phases. In 10 of 11 patients in which the diet was labeled with [(111)In] DTPA, reflux was documented at a given time of the feeding period. Bile acid concentrations in the stomach increased from 392 (61-1076) (fasting) to 1446 (320-2770) micromol/l (feeding) (p = 0.010) and mean glucose concentration increased from 59 (28-95) to 164 (104-449) mg/dl (p = 0.006). CONCLUSION Duodenogastric reflux is common in mechanically ventilated critically ill patients with nasojejunal feeding tubes. It occurs both during fasting and during nasojejunal feeding. During nasojejunal feeding, moderate alkalinization of the gastric contents occurs as a result of bile and nutrient reflux.

Abstract
This study assesses duodenogastric reflux (DGR) using 99mTechnetium-diisopropyl iminodiacetic acid in unoperated dogs and in dogs 28 days after a Billroth II gastrectomy and 28 days after the Henley procedure. Fourteen mongrel dogs were divided randomly into two groups of seven each, according to the length of the interposed jejunal segment used (Group A 10 cm; Group B, 20 cm). All dogs were subjected to a Billroth II gastrectomy, followed by the Henley procedure 30 days later. In Group A, DGR was significantly lower in the preoperative period (median, 0.0%; range, 0.0-0.02%) than after gastrectomy (median, 0.13%; range, 0.08-0.70%) and the Henley procedure (median, 0.12%; range, 0.06-0.22%), but did not differ significantly after gastrectomy and jejunal interposition. In Group B, DGR was significantly higher after gastrectomy (median, 0.15%; range, 0.10-0.64%) than in the preoperative period (median, 0.00%; range, 0.00-0.09%) or than after the Henley procedure (median, 0.00%; range, 0.00-0.7%). DGR did not differ significantly between the preoperative period and after Henley procedure. After jejunal interposition, DGR was significantly higher in Group A than in Group B. The Henley procedure is effective in preventing DGR when the interposed segment is 20 cm in length.
