Abstract
OBJECTIVES Reflux hypersensitivity (RH) is a form of refractory gastroesophageal reflux disease in which duodenogastroesophageal reflux (DGER) plays a role. This study aimed to determine the usefulness of an endoscopy system equipped with image-enhanced technology for evaluating DGER and RH. METHODS The image enhancement mode for detecting bilirubin and calculated values were defined as the Bil mode and Bil value, respectively. First, the visibility of the Bil mode was validated for a bilirubin solution and bile concentrations ranging from 0.01% to 100% (0.002-20 mg/dL). Second, visibility scores of the Bil mode, when applied to the porcine esophagus sprayed with a bilirubin solution, were compared to those of the blue laser imaging (BLI) and white light imaging (WLI) modes. Third, a clinical study was conducted to determine the correlations between esophageal Bil values and the number of nonacid reflux events (NNRE) during multichannel intraluminal impedance-pH monitoring as well as the utility of esophageal Bil values for the differential diagnosis of RH. RESULTS Bilirubin solution and bile concentrations higher than 1% were visualized in red using the Bil mode. The visibility score was significantly higher with the Bil mode than with the BLI and WLI modes for 1% to 6% bilirubin solutions (P < 0.05). The esophageal Bil value and NNRE were significantly positively correlated (P = 0.031). The area under the receiver operating characteristic curve for the differential diagnosis of RH was 0.817. CONCLUSION The Bil mode can detect bilirubin with high accuracy and could be used to evaluate DGER in clinical practice.

Abstract
BACKGROUND Although bile reflux plays an important role in the development of Barrett's esophagus, the relationship between endoscopic findings of bile reflux and Barrett's esophagus remains unclear. OBJECTIVE This study evaluated whether endoscopic evidence of bile reflux was associated with the presence of Barrett's esophagus. METHODS A retrospective analysis of a prospectively maintained database comprising consecutive patients who underwent screening esophagogastroduodenoscopy was conducted. Endoscopic evidence of bile reflux was defined as the presence of bile-stained fluid in the gastric fundus. We performed multivariate analysis to identify predictive factors that differed significantly between patients with and without Barrett's esophagus. RESULTS Of 4021 patients, 922 (23%) had Barrett's esophagus, and 1000 (25%) showed endoscopic findings of bile reflux. Multivariate analysis revealed endoscopic evidence of bile reflux as the strongest independent factor associated with the presence of Barrett's esophagus (odds ratio [OR] 5.65, 95% confidence interval [CI] 4.71-6.76) in relation to the presence of hiatal hernia (OR 3.30, 95% CI 2.70-4.04) and male gender (OR 1.54, 95% CI 1.24-1.91). CONCLUSIONS Endoscopic evidence of bile reflux was independently associated with the presence of Barrett's esophagus. This finding might help identify patients at future risk of Barrett's esophagus who could benefit from increased endoscopy surveillance.

Abstract
Objective To explore the risk factors of duodenogastric reflux (DGR) in relation to different dietary habits. Methods A total of 106 patients with symptoms of DGR who underwent electronic gastroscopy from June 2019 to June 2020 were selected and divided into the DGR group (n = 33) and the non-DGR group (n = 73) according to the diagnosis of bile reflux. Questionnaires were used to collect the basic information and dietary habits of the patients, including age, gender, body mass index, place of residence, comorbidities, dietary composition, salt intake, smoking and drinking consumption. The total bile acid (TBA) and cholesterol (CHO) of the gastric juice were measured using a fully automated biochemical analyser, with an enzyme-linked immunosorbent assay used for the serum cholecystokinin, gastrin and gastrin levels. Univariate analysis and multivariate logistic regression analysis were used to predict the attendant DGR risk factors. Results There was no significant difference in age or gender between the DGR and the non-DGR groups (P > 0.05). The proportion of patients living in the Bashang region was significantly higher in the DGR group (78.79%) than in the non-DGR group (38.36%) (P < 0.05). The levels of TBA and CHO in the gastric juice and the cholecystokinin and gastrin levels in the serum of the DGR group were higher than those in the non-DGR group, while the serum motilin levels were significantly lower in the DGR group than in the non-DGR group (P < 0.05). The univariate analysis indicated that the proportion of patients with daily consumption of dairy products and fried foods, a high salt intake and smoking and drinking consumption were significantly higher in the DGR than in the non-DGR group (P < 0.05). Conclusion The daily consumption of dairy products and a preference for fried food are independent risk factors for the occurrence of DGR (odds ratio ≥ 1, P < 0.05).

Abstract
The growing epidemic of obesity and the increase in weight loss surgery has led to a resurgence of interest in biliary reflux because anatomical alterations may be refluxogenic. HIDA scan is the least invasive scan with good patient tolerability, sensitivity and reproducibility for the diagnosis of biliary reflux. Patients with more advanced oesophageal lesions have a higher degree of duodenal reflux. It has been shown in animal models and in vitro that there is more Barrett's and dysplasia with duodenal reflux. There are two cases of post-OAGB malignancy reported in 20 years, both without correlation with a biliary aetiology, so the carcinogenic risk probably remains theoretical. Prospective trials on OAGB should include endoscopy preoperatively and at 5-year intervals, to have data on the real effects of bile exposure on the gastric reservoir and oesophagus.

Obes Surg 2023; 33:870-878.

Abstract
PURPOSE OAGB is the third most common bariatric surgery. Biliary reflux (BR) is an inherent complication of this unique anatomy, although there is still controversy regarding its significance and long-term risks including carcinogenesis. To date, there is no effective treatment for BR with conversion to RYGB reserved for refractory patients. TORe is an effective treatment for weight-regain and dumping syndrome after RYGB. We hypothesized that narrowing the anastomosis would decrease the amount of bile refluxate entering the stomach and esophagus in patients with BR symptoms after OAGB and alleviate symptoms. The purpose of this study is to evaluate the efficacy of TORe for the treatment of BR symptoms after OAGB. MATERIALS AND METHODS BR was diagnosed clinically in patients after OAGB using the gastroesophageal reflux disease health-related quality of life (GERD-HRQL) instrument after treatment with high-dose proton pump inhibitor (PPI) excluded possible acid reflux. TORe was carried out using a suture pattern that narrowed and elongated the anastomosis. All patients were prospectively followed. RESULTS Twelve patients, post-OAGB, underwent TORe for BR. Symptoms resolved in 9 (75%) patients. GERD-HRQL score at 6 months declined from an average of 33.7 (SD 1.9) before the procedure to 16.1 (SD 10, p < 0.001). In one case, a small perforation was identified during the procedure and was immediately sutured with no further sequela. DISCUSSION TORe appears a safe and effective treatment for BR symptoms after OAGB, at least in the short term. Accurate tools for BR diagnosis, a larger cohort, and longer follow-up periods are needed to better show the effectiveness and durability of this treatment option.

Abstract
This article systematizes available data from the literature on biliary gastritis (BG) in order to increase the awareness of specialists about the latest possibilities for diagnosing the disease. BG occurs as a result of pathological duodenogastric reflux. In patients with a preserved duodenogastric junction, the dominant factor is represented by motor disorders of the upper digestive tract (primary biliary gastritis), while in patients recovering from surgical interventions it is represented by structural changes (secondary biliary gastritis). Progressive BG can lead to atrophy of the gastric mucosa, intestinal metaplasia, epithelial dysplasia, and eventually to gastric cancer. Diagnostic methods for BG are carried out to identify risk factors, exclude alarm symptoms and identify persistent motor disorders and pathological reflux (24 h pH-impedancemetry, hepatobiliary scintigraphy, 24 h monitoring of bilirubin content in the reflux using a Bilitec 2000 photometer), as well as to diagnose gastritis itself (esophagogastroduodenoscopy, morphological gastrobiopsy examination). The diagnosis of BG should be based on a multidisciplinary approach that combines a thorough analysis of a patient’s complaints, an anamnesis of the disease, and the results of endoscopic and histological research methods.

Abstract
Bile reflux gastritis (BRG), a kind of gastrointestinal disorder in clinical practice, is characterized by regurgitation and inflammation. However, lack of guidelines leads to simple cognition and even ignorance of this disease for clinicians. Primarily, making the pathogenesis of BRG clear contributes to a correct and general understanding of this disease for physicians. Next, although recently there has been an increasing awareness among researchers in terms of the relevant factors for BRG, further studies involving large samples are still required to certify the relationship between them explicitly. Besides, researches have established that BRG is closely associated with the development of precancerous lesions and gastric cancer. Till now, there is still no golden standard for diagnosis of BRG. Nevertheless, advances in techniques, especially extensive applications of endoscopy and chemical analysis of reflux contents, have improved our ability to identify the occurrence of this disease as well as distinguishing physiological reflux from pathological reflux. Finally, it is fortunate for patients that more and more importance has been attached to the treatment of BRG. From lifestyle modification to drug therapy to surgery, all of them with the view of realizing symptomatic relief are employed for patients with BRG. In this review, we briefly evaluate this disorder based on the best available evidence, offering an overview of its complicated pathogenesis, diverse relevant factors, potential carcinomatous risk, modern diagnostic investigations, and effective therapeutic plans.
