Meta-Analysis
BACKGROUND/OBJECTIVE
The involvement of hydrochloric acid in the etiology of eosinophilic esophagitis and numerous reports on its coexistence and interaction with reflux disease, as well as the rings of the esophageal mucosa formed with the advancement of the disease, suggest a potential association of eosinophilic esophagitis with another disorder of esophageal morphology potentially caused by exposure to acid reflux-Schatzki ring. Therefore, it seems reasonable to check the relationship of eosinophilic esophagitis with the coexistence of the Schatzki ring as a potential effect of advanced esophageal trachealization, which is the subject of this systematic review with a meta-analysis.
METHODS
The protocol of this meta-analysis was performed according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. A systematic search of the indexed literature in the MEDLINE and Scopus databases from early to December 2019 was performed to identify all original research articles on the association between the occurrence of the Schatzki ring and eosinophilic esophagitis in adults.
RESULTS
Out of 68 searched studies, after the analysis and evaluation of the works, only 4 met the criteria set according to the protocol and were included in the meta-analysis. Based on the performed meta-analysis, no relationship was found between the occurrence of Schatzki ring and eosinophilic esophagitis.
CONCLUSION
The present study did not show a significant relationship between the occurrence of the Schatzki ring and eosinophilic esophagitis in the adult population, which suggests that these are two independent causes of dysphagia in this patient population.

Meta-Analysis
BACKGROUND
Indian population-based studies on the prevalence and risk factors for gastroesophageal reflux disease (GERD) are scanty, and a meta-analysis and a meta-regression of prevalence and risk factors based on the existing data have not yet been reported.
METHODS
A systematic review of all the available publications from India reporting data regarding prevalence and risk factors of GERD was performed. Heterogeneity was assessed using I statistics. The meta-analysis was undertaken to measure the average proportion reported in the existing studies, and meta-regression models were used to explore the risk factors for it.
RESULTS
The nine studies included 20,614 subjects; the prevalence of GERD ranged from 5% to 28.5%. The summary effect size (weighted average proportion) estimated by meta-analytic model was 0.1415 (95% confidence interval [CI] 0.099 to 0.197). The results for the test of heterogeneity that included tau (0.37, 95% CI 0.21 to 1.80), I (98.9%, 95% CI 98.01 to 99.77), and the Q-statistic (707.670; p < 0.0001) suggested high heterogeneity in the effect sizes. The pooled proportion of GERD (random-effects model) was 15.573 (95% CI 11.046 to 20.714). In the meta-regression model, sample size (p = 0.005) explained about 50% of the heterogeneity.
CONCLUSION
The pooled prevalence of GERD in the Indian population is 15.6 (95% CI 11.046 to 20.714). The risk factors were age, body mass index (BMI), non-vegetarian diet, tea/coffee intake, tobacco, and alcohol consumption. However, there was significant heterogeneity in the studies.

BACKGROUND AND STUDY AIMS
Benign esophageal strictures are primarily treated with dilation therapy, but strictures can recur or can be unresponsive, requiring additional or repeated treatment. This study investigates the efficacy and safety of intralesional steroid injections in addition to dilation in comparison to dilation alone in patients with benign refractory or recurrent esophageal strictures.
METHODS
A systematic search was carried out in PubMed, using the search terms "Esophageal Stenosis"[Mesh] AND "Injections, Intralesional"[Mesh]. In addition, the reference list of all selected articles was searched manually for other relevant articles. All clinical trials and case series were considered.
RESULTS
This systematic review included four randomized controlled trials, six case series and two cohort studies, comprising 341 patients with benign esophageal strictures of different etiologies. A benefit of adding intralesional steroid injections to dilation in reducing the need for repeat dilation was seen in the subgroups of peptic, radiation-induced and corrosive strictures. Results were inconsistent for anastomotic strictures and too limited for strictures due to eosinophilic esophagitis, sclerotherapy or pill esophagitis. Complications were rare and of limited severity.
CONCLUSION
Endoscopic dilation remains the first-line treatment, since its efficacy and safety are mostly satisfactory. In recurrent or refractory strictures, intralesional steroid injections are advised in peptic strictures and can be considered in radiation- induced, corrosive strictures and anastomotic strictures. It is recommended to restrict the steroid use to a maximum of three sessions and to consider alternative treatment if treatment effects remain insufficient.

PloS One 2020To investigate the role of gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) in the development of dental disorders.
OBJECTIVES
To investigate the role of gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) in the development of dental disorders.
METHODS
The first outcome was review of the role of reflux in the development of dental disorders in adults. The second outcome was review of the potential pathophysiological mechanisms underlying the association between reflux and dental disorders. Three investigators screened publications for eligibility and exclusion based on predetermined criteria through a literature search conducted on PubMed, Cochrane Library, and Scopus according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
RESULTS
From 386 publications, 24 studies were kept for analysis. Objective approaches were used in 16 studies to confirm GERD diagnosis. Pharyngeal reflux episodes (LPR) were considered in 2 studies. No study considered nonacid reflux. The study results supported a higher prevalence of dental erosion and caries in reflux patients compared with healthy individuals. Patients with dental erosion have a higher prevalence of reflux than controls. The pathophysiological mechanisms would involve changes in the saliva physiology. No study investigated the microbiota modifications related to reflux although the findings are supporting the critical role of microbiota change in the development of dental disorders. There is an important heterogeneity between studies about diagnostic methods and clinical outcome evaluation.
CONCLUSION
The involvement of reflux in the development of dental disorders is not formally demonstrated and requires future investigations considering pharyngeal acid and nonacid reflux episodes and in particular their potential impact on oral microbiota.

Meta-Analysis
INTRODUCTION
Peroral endoscopic myotomy (POEM) demonstrated similar efficacy to surgical myotomy in the management of achalasia. However, gastroesophageal reflux disease (GERD) is common after POEM. The aim of this study is to identify factors associated with GERD after POEM.
METHOD
After searching electronic databases, randomized trials and observational studies including patients with achalasia or other spastic esophageal disorders, treated by POEM, and providing GERD data were selected. GERD was evaluated by 3 methods: pH monitoring, endoscopic findings, and symptoms. For each method, an analysis was performed comparing the outcomes related to the following independent variables: full-thickness (FT) vs circular myotomy, anterior vs posterior, long myotomy vs short myotomy, naive vs previous treatment failure, previous Heller myotomy (HM) vs non-previous-HM, Type I vs II, Type I vs III, and Type II vs III.
RESULTS
2869 publications were identified, and 25 studies met criteria for inclusion in the qualitative analysis. Of these, 18 were included in the meta-analysis. According to the endoscopic findings, circular and anterior myotomy demonstrated a lower trend of GERD with borderline significance (p = 0.06; p = 0.07, respectively). In the pH monitoring and symptom analyses, circular myotomy, anterior myotomy, treatment naive, and non-HM patients were associated with a lower occurrence of GERD; however, no statistically significant difference was found. When comparing achalasia subtypes, no statistical difference was found in all analyses.
CONCLUSION
This systematic review and meta-analysis suggest that a circular anterior approach may limit post-POEM GERD and should be considered in appropriate patients.

European Archives of... Dec 2019To develop clinical tools assessing the refluxogenic potential of foods and beverages (F&B) consumed by patients with laryngopharyngeal reflux (LPR).
OBJECTIVE
To develop clinical tools assessing the refluxogenic potential of foods and beverages (F&B) consumed by patients with laryngopharyngeal reflux (LPR).
METHODS
European experts of the LPR Study group of the Young-Otolaryngologists of the International Federation of Oto-rhino-laryngological societies were invited to identify the components of Western European F&B that would be associated with the development of LPR. Based on the list generated by experts, four authors conducted a systematic review to identify the F&B involved in the development of esophageal sphincter and motility dysfunctions, both mechanisms involved in the development of gastroesophageal reflux disease and LPR. Regarding the F&B components and the characteristics identified as important in the development of reflux, experts developed three rational scores for the assessment of the refluxogenic potential of F&B, a dish, or the overall diet of the patient.
RESULTS
Twenty-six European experts participated to the study and identified the following components of F&B as important in the development of LPR: pH; lipid, carbohydrate, protein composition; fiber composition of vegetables; alcohol degree; caffeine/theine composition; and high osmolality of beverage. A total of 72 relevant studies have contributed to identifying the Western European F&B that are highly susceptible to be involved in the development of reflux. The F&B characteristics were considered for developing a Refluxogenic Diet Score (REDS), allowing a categorization of F&B into five categories ranging from 1 (low refluxogenic F&B) to 5 (high refluxogenic F&B). From REDS, experts developed the Refluxogenic Score of a Dish (RESDI) and the Global Refluxogenic Diet Score (GRES), which allow the assessment of the refluxogenic potential of dish and the overall diet of the LPR patient, respectively.
CONCLUSION
REDS, RESDI and GRES are proposed as objective scores for assessing the refluxogenic potential of F&B composing a dish or the overall diet of LPR patients. Future studies are needed to study the correlation between these scores and the development of LPR according to impedance-pH study.

Comparative Study Meta-Analysis
BACKGROUND
In theory, proximal gastrectomy with double-tract reconstruction (PG-DT) was superior to total gastrectomy (TG) in hematologic and nutritional outcomes. However, its clinical effects in proximal early gastric cancer (EGC) have been controversial.
METHODS
The purpose of this study was to investigate the outcomes of laparoscopic proximal gastrectomy with double-tract reconstruction (LPG-DT) for proximal EGC. For this systematic review and meta-analysis, we searched for articles published before December of 2018 in the following databases: PubMed, Web of Science, EBSCO, Medline, and Cochrane Library.
RESULTS
The results showed no significant difference in the anastomotic stenosis (OR = 0.91, 95%CI = 0.33-2.50, p = 0.85) and reflux esophagitis (OR = 1.87, 95%CI = 0.62-5.65, p = 0.27) between LPG-DT and laparoscopic total gastrectomy (LTG). The vitamin B12 supplementation rate in the LPG-DT group was lower than the LTG group (OR = 0.06, 95%Cl = 0.01-0.59, p = 0.02).
CONCLUSIONS
Due to comparable clinical effect, PG-DT is comparable to TG for patients with proximal EGC. In addition, LPG-DT not only appears superior to TG in terms of preventing vitamin B12 deficiency, but also does not increase the risk of anastomotic stricture and reflux esophagitis.

Meta-Analysis
BACKGROUND
Increasing evidence indicates that nonalcoholic fatty liver disease (NAFLD) is linked to an increased risk of extra-hepatic conditions. However, it is currently uncertain whether NAFLD is associated with the risk of gastroesophageal reflux disease (GERD). We performed a systematic review and meta-analysis of relevant studies to examine the association between NAFLD and the risk of GERD.
METHODS
We searched PubMed, Scopus, Embase and Web of Science from 1 January 1975 to 15 December 2018, using predefined terms to identify cross-sectional, case-control and cohort studies investigating the association between NAFLD and GERD.
RESULTS
Nine observational studies involving 185 118 subjects were eligible for inclusion in the meta-analysis. Overall, NAFLD was significantly associated with an increased risk of GERD (random effect OR 1.28; 95% CI: 1.12-1.44, I = 82%). Moreover, the significant association between NAFLD and GERD was consistent both for studies with adjusted OR/HR (n = 6, random effect OR = 1.16, 95% CI: 1.03-1.30) and those with unadjusted OR/HR (n = 3, random effect OR = 2.09, 95% CI: 1.62-2.56) as measures of effect. Both funnel plot and Egger's test suggested the existence of publication bias. However, a sensitivity analysis by sequentially omitting each study did not alter the pooled outcome,suggesting the robustness of the association.
CONCLUSION
NAFLD is associated with an increased risk of GERD. However, future large and cohort studies are still needed to determine the causal relationship between NAFLD and the risk of GERD.

Meta-Analysis
BACKGROUND AND AIM
Gastroesophageal reflux disease (GERD) is a common disease caused by reflux of gastric contents to the esophagus. Proton-pump inhibitors (PPIs) are recommended as a first-line therapy to treat GERD. Recently, a new potassium-competitive acid blocker, vonoprazan, was launched in Japan. We aimed to evaluate the comparative efficacy of vonoprazan and other PPIs in healing GERD.
METHODS
We used MEDLINE and the Cochrane Central Register of Controlled Trials to search the literature. Double-blind randomized controlled trials for PPIs and/or vonoprazan that were published in English or Japanese and assessed healing effects in adult GERD patients were included. To estimate the comparative efficacy of treatments, we performed a Bayesian network meta-analysis to assess the consistency assumption.
RESULTS
Of 4001 articles identified in the database, 42 studies were eligible. One study was hand-searched and added to the analysis. For the main analysis of healing effects at 8 weeks, odds ratios (ORs) of vonoprazan (20 mg daily) to esomeprazole (20 mg), rabeprazole (20 mg), lansoprazole (30 mg), and omeprazole (20 mg) were 2.29 (95% credible interval, 0.79-7.06), 3.94 (1.15-14.03), 2.40 (0.90-6.77), and 2.71 (0.98-7.90), respectively. Subgroup analysis for patients with severe esophagitis at baseline showed significantly higher ORs for vonoprazan versus most of the comparator PPIs.
CONCLUSIONS
This analysis shows that the GERD healing effect of vonoprazan is higher than that of rabeprazole (20 mg) but not higher than other PPIs. Subgroup analysis indicated that vonoprazan is more effective than most PPIs for patients with severe erosive esophagitis.
