AIM:To determine whether an increased number and duration of non-acid reflux events as measured using the multichannel intraluminal impedance pH(MII-pH)is linked to gastroparesis(GP).METHODS:A case control study was conducted in which 42 patients undergoing clinical evaluation for continued symptoms of gastroesophageal reflux disease(both typical and atypical symptoms)despite acid suppression therapy.MII-pH technology was used over 24 h to detect reflux episodes and record patients’symptoms.Parameters evaluated in patients with documented GP and controls without GP by scintigraphy included total,upright,and supine number of acid and non-acid reflux episodes(pH<4 and pH>4,respectively),the duration of acid and non-acid reflux in a 24-h period,and the number of reflux episodes lasting longer than 5 min.RESULTS:No statistical difference was seen between the patients with GP and controls with respect to the total number or duration of acid reflux events,total number and duration of non-acid reflux events or the duration of longest reflux episodes.The number of nonacid reflux episodes with a pH>7 was higher in subjects with GP than in controls.In addition,acid reflux episodes were more prolonged(lasting longer than 5min)in the GP patients than in controls;however,these values did not reach statistical significance.Thirty-five patients had recorded symptoms during the 24 h study and of the 35 subjects,only 9%(n=3)had a positive symptom association probability(SAP)for acid/non-acid reflux and 91%had a negative SAP.CONCLUSION:The evaluation of patients with a documented history of GP did not show an association between GP and more frequent episodes of non-acid reflux based on MII-pH testing. 展开更多

BACKGROUND Clinical studies have reported that patients with gastroesophageal reflux disease(GERD)have a higher prevalence of hypertension.AIM To performed a bidirectional Mendelian randomization(MR)analysis to investi-gate the causal link between GERD and essential hypertension.METHODS Eligible single nucleotide polymorphisms(SNPs)were selected,and weighted median,inverse variance weighted(IVW)as well as MR egger(MR-Egger)re-gression were used to examine the potential causal association between GERD and hypertension.The MR-Pleiotropy RESidual Sum and Outlier analysis was used to detect and attempt to reduce horizontal pleiotropy by removing outliers SNPs.The MR-Egger intercept test,Cochran’s Q test and“leave-one-out”sen-sitivity analysis were performed to evaluate the horizontal pleiotropy,heterogen-eities,and stability of single instrumental variable.RESULTS IVW analysis exhibited an increased risk of hypertension(OR=1.46,95%CI:1.33-1.59,P=2.14E-16)in GERD patients.And the same result was obtained in replication practice(OR=1.002,95%CI:1.0008-1.003,P=0.000498).Meanwhile,the IVW analysis showed an increased risk of systolic blood pressure(β=0.78,95%CI:0.11-1.44,P=0.021)and hypertensive heart disease(OR=1.68,95%CI:1.36-2.08,P=0.0000016)in GERD patients.Moreover,we found an decreased risk of Barrett's esophagus(OR=0.91,95%CI:0.83-0.99,P=0.043)in essential hypertension patients.CONCLUSION We found that GERD would increase the risk of essential hypertension,which provided a novel prevent and therapeutic perspectives of essential hypertension. 展开更多

Achalasia cardia,the most prevalent primary esophageal motility disorder,is predominantly characterized by symptoms of dysphagia and regurgitation.The principal therapeutic approaches for achalasia encompass pneumatic dilatation(PD),Heller's myotomy,and the more recent per-oral endoscopic myotomy(POEM).POEM has been substantiated as a safe and efficacious modality for the management of achalasia.Although POEM demonstrates superior efficacy compared to PD and an efficacy parallel to Heller's myotomy,the incidence of gastroesophageal reflux disease(GERD)following POEM is notably higher than with the aforementioned techniques.While symptomatic reflux post-POEM is relatively infrequent,the significant occurrence of erosive esophagitis and heightened esophageal acid exposure necessitates vigilant monitoring to preclude long-term GERD-related complications.Contemporary advancements in the field have enhanced our comprehension of the risk factors,diagnostic methodologies,preventative strategies,and therapeutic management of GERD subsequent to POEM.This review focuses on the limitations inherent in the 24-h pH study for evaluating post-POEM reflux,potential modifications in the POEM technique to mitigate GERD risk,and the strategies for managing reflux following POEM. 展开更多

Gastroesophageal reflux disease(GERD)is a prevalent global health concern with a rising incidence.Various risk factors,including obesity,hiatal hernia,and smo-king,contribute to its development.Recent research suggests associations bet-ween GERD and metabolic syndrome,cardiac diseases,and hypertension(HTN).Mechanisms linking GERD to HTN involve autonomic dysfunction,inflammatory states,and endothelial dysfunction.Furthermore,GERD medications such as pro-ton-pump inhibitors may impact blood pressure regulation.Conversely,antihy-pertensive medications like beta-blockers and calcium channel blockers can exacerbate GERD symptoms.While bidirectional causality exists between GERD and HTN,longitudinal studies are warranted to elucidate the precise relationship.Treatment of GERD,including anti-reflux surgery,may positively influence HTN control.However,the interplay of lifestyle factors,comorbidities,and medications necessitates further investigation to comprehensively understand this relation-ship.In this editorial,we comment on the article published by Wei et al in the recent issue of the World Journal of Clinical Cases.We evaluate their claims on the causal association between GERD and HTN. 展开更多

Introduction: Gastroesophageal reflux disease (GERD) is a benign and chronic disease that can impair the quality of life. Objective: To study the epidemiological, clinical aspects and factors associated with typical GERD in the general population of Parakou in the Republic of Benin. Methods: This was a descriptive and analytical cross-sectional study with prospective data collection which took place from May 1, 2019 to June 30, 2019. The study population consisted of any subject aged at least 15 years and living in Parakou. Subjects aged at least 15 years, present on the day of the survey and having given their free and informed verbal consent were included. The Short form of QRS®(Reflux-Qual Short form) questionnaire and the “Hospital Anxiety and Depression” score were used to assess the quality of life and anxiety/depression, respectively. The sampling was probabilistic through a 2-stage cluster sampling. The variable of interest was the presence of GERD. Results: Out of 390 subjects surveyed, 28 had symptoms of typical GERD, representing a prevalence of 7.18%. The average age of these subjects was 27.11 ± 7.88 years. Fifteen subjects (53.57%) were male, giving a sex ratio of 1.15. Fourteen (50%) had a secondary level of education, 12 (42.86%) were pupils/students, 18 (64.29%) were single. The monthly income of 22 subjects (78.57%) was lower than the guaranteed interprofessional minimum wage (40,000 FCFA). The average duration of progression of symptoms was 15.89 ± 4.97 months. Symptoms occurred less than twice a week in 22 subjects (78.57%). The clinical manifestations were both diurnal and nocturnal in 12 subjects (42.86%). None of the 28 subjects with GERD had clinical warning signs. Asthma, diabetes, consumption of high fat or spice foods, carbonated drinks, non-steroidal anti-inflammatory drugs, alcoholic beverages and tobacco were statistically associated with the occurrence of GERD. Each of the 28 subjects had at least one associated factor. A significant impair in quality of life was observed in 27 patients (96.43%). Conclusion: Typical GERD is relatively common in the general population of Parakou in the Republic of Benin. It often affects young males. Among the risk factors identified, the most common are carbonated drinks, spicy meals and diabetes. GERD significantly impairs quality of life. Raising awareness about the disease and its associated factors is necessary among the general population. 展开更多

BACKGROUND Gastroesophageal reflux disease(GERD)is a common complication of esophageal cancer surgery that can affect quality of life and increase the risk of esophageal stricture and anastomotic leakage.Wendan Decoction(WDD)is a traditional Chinese herbal formula used to treat various gastrointestinal disorders,such as gastritis,functional dyspepsia,and irritable bowel syndrome.Mosapride,a prokinetic agent,functions as a selective 5-hydroxytryptamine 4 agonist,enhancing gastrointestinal motility.AIM To evaluate the therapeutic effects of WDD combined with mosapride on GERD after esophageal cancer surgery.METHODS Eighty patients with GERD were randomly divided into treatment(receiving WDD combined with mosapride)and control(receiving mosapride alone)groups.The treatment was conducted from January 2021 to January 2023.The primary outcome was improved GERD symptoms as measured using the reflux disease questionnaire(RDQ).The secondary outcomes were improved esophageal motility(measured using esophageal manometry),gastric emptying(measured using gastric scintigraphy),and quality of life[measured via the Short Form-36(SF-36)Health Survey].RESULTS The treatment group showed a notably reduced RDQ score and improved esophageal motility parameters,such as lower esophageal sphincter pressure,peristaltic amplitude,and peristaltic velocity compared to the control group.The treatment group showed significantly higher gastric emptying rates and SF-36 scores(in both physical and mental domains)compared to the control group.No serious adverse effects were observed in either group.CONCLUSION WDD combined with mosapride is an effective and safe therapy for GERD after esophageal cancer surgery.It can improve GERD symptoms,esophageal motility,gastric emptying,and the quality of life of patients.Further studies with larger sample sizes and longer follow-up periods are required to confirm these findings. 展开更多

BACKGROUND Gastro-esophageal reflux disease(GERD)may affect the upper digestive tract;up to 20%of population in Western nations are affected by GERD.Antacids,histamine H2-receptor antagonists,and Proton Pump Inhibitors(PPIs)are considered the referring medications for GERD.Nevertheless,PPIs must be managed carefully because their use,especially chronic,could be linked with some adverse effects.An effective and safe alternative pharmacological tool for GERD is needed.After the identification of potentially new medications to flank PPIs,it is mandatory to revise and improve good clinical practices even through a consensus process.AIM To optimize diagnosis and treatment guidelines for GERD through a consensus based on Delphi method.METHODS The availability of clinical studies describing the action of the multicomponent/multitarget medication Nux vomica-Heel,subject of the consensus,is the basic prerequisite for the consensus itself.A modified Delphi process was used to reach a consensus among a panel of Italian GERD specialists on the overlapping approach PPIs/Nux vomica-Heel as a new intervention model for the management of GERD.The Voting Consensus group was composed of 49 Italian Medical Doctors with different specializations:Gastroenterology,otolaryngology,geriatrics,and general medicine.A scientific committee analyzed the literature,determined areas that required investigation(in agreement with the multiple-choice questionnaire results),and identified two topics of interest:(1)GERD disease;and(2)GERD treatment.Statements for each of these topics were then formulated and validated.The Delphi process involved two rounds of questioning submitted to the panel experts using an online platform.RESULTS According to their routinary GERD practice and current clinical evidence,the panel members provided feedback to each questionnaire statement.The experts evaluated 15 statements and reached consensus on all 15.The statements regarding the GERD disease showed high levels of agreement,with consensus ranging from 70%to 92%.The statements regarding the GERD treatment also showed very high levels of agreement,with consensus ranging from 90%to 100%.This Delphi process was able to reach consensus among physicians in relevant aspects of GERD management,such as the adoption of a new approach to treat patients with GERD based on the overlapping between PPIs and Nux vomica-Heel.The consensus was unanimous among the physicians with different specializations,underlying the uniqueness of the agreement reached to identify in the overlapping approach between PPIs and Nux vomica-Heel a new intervention model for GERD management.The results support that an effective approach to deprescribe PPIs through a progressive decalage timetable(reducing PPIs administration to as-needed use),should be considered.CONCLUSION Nux vomica-Heel appears to be a valid opportunity for GERD treatment to favor the deprescription of PPIs and to maintain low disease activity together with the symptomatology remission. 展开更多

BACKGROUND Reflux esophagitis has an increasing prevalence and complex and diverse symptoms.Identifying its risk factors is crucial to understanding the etiology,prevention,and management of the disease.The occurrence of reflux esophagitis may be associated with food reactions,Helicobacter pylori(H.pylori)infection,and metabolic syndromes.AIM To investigate the risk factors for reflux esophagitis and analyze the effects of immunoglobulin(Ig)G-mediated food intolerance,H.pylori infection,and metabolic syndrome on reflux esophagitis.METHODS Outpatients attending the Second Medical Center of the PLA General Hospital between 2017 and 2021 were retrospectively enrolled.The patients’basic information,test results,gastroscopy results,H.pylori test results,and IgG-mediated food intolerance results were collected.Multivariate logistic regression analysis was used to analyze risk factors for reflux esophagitis.Statistical mediation analysis was used to evaluate the effects of IgG-mediated food intolerance and metabolic syndrome on H.pylori infection affecting reflux esophagitis.RESULTS A total of 7954 outpatients were included;the prevalence of reflux esophagitis,IgG-mediated food intolerance,H.pylori infection,and metabolic syndrome were 20.84%,61.77%,35.91%,and 60.15%,respectively.Multivariate analysis showed that the independent risk factors for reflux esophagitis included IgG-mediated food intolerance(OR=1.688,95%CI:1.497-1.903,P<0.00001)and metabolic syndrome(OR=1.165,95%CI:1.030-1.317,P=0.01484),and the independent protective factor for reflux esophagitis was H.pylori infection(OR=0.400,95%CI:0.351-0.456,P<0.00001).IgG-mediated food intolerance had a partially positive mediating effect on H.pylori infection as it was associated with reduced occurrence of reflux esophagitis(P=0.0200).Metabolic syndrome had a partially negative mediating effect on H.pylori infection and reduced the occurrence of reflux esophagitis(P=0.0220).CONCLUSION Patients with IgG-mediated food intolerance and metabolic syndrome were at higher risk of developing reflux esophagitis,while patients with H.pylori infection were at lower risk.IgG-mediated food intolerance reduced the risk of reflux esophagitis pathogenesis in patients with H.pylori infection;however,metabolic syndrome increased the risk of patients with H.pylori infection developing reflux esophagitis. 展开更多

The peroral endoscopic myotomy(POEM)procedure has revolutionized the management of achalasia in many centres around the world as it offers patients a minimally invasive endoscopic solution to their dysphagia caused by achalasia.Alongside its success in alleviating dysphagia,concerns regarding postoperative gastroesophageal reflux disease have emerged as a pertinent issue which are not fully resolved.In this study,Nabi et al have comprehensively reviewed the topic of the prediction,prevention and management of gastroesophageal reflux after POEM.POEM is a purely endoscopic procedure which is usually performed without any anti-reflux procedure.Certain patients may be better served by a laparoscopic Heller’s myotomy and fundoplication and it is important that gastroenterologists and surgeons provide comprehensive risks and benefits of each achalasia treatment option so that patients can decide what treatment is best for them.This article by Nabi et al provides a comprehensive review of the current status of this issue to allow these discussions to occur. 展开更多

In this editorial,we respond to a review article by Nabi et al,in which the authors discussed gastroesophageal reflux(GER)following peroral endoscopic myotomy(POEM).POEM is presently the primary therapeutic option for achalasia,which is both safe and effective.A few adverse effects were documented after POEM,including GER.The diagnostic criteria were not clear enough because approximately 60%of patients have a long acid exposure time,while only 10%experience reflux symptoms.Multiple predictors of high disease incidence have been identified,including old age,female sex,obesity,and a baseline lower esophageal sphincter pressure of less than 45 mmHg.Some technical steps during the procedure,such as a lengthy or full-thickness myotomy,may further enhance the risk.Proton pump inhibitors are currently the first line of treatment.Emerging voices are increasingly advocating for the routine combining of POEM with an endoscopic fundoplication method,such as peroral endoscopic fundoplication or transoral incisionless fundoplication.However,more research is necessary to determine the safety and effectiveness of these procedures in the long term for patients who have undergone them. 展开更多

BACKGROUND Currently,the primary treatment for gastroesophageal reflux is acid suppression with proton pump inhibitors,but they are not a cure,and some patients don’t respond well or refuse long-term use.Therefore,alternative therapies are needed to understand the disease and develop better treatments.Laparoscopic anti-reflux surgery(LARS)can resolve symptoms of these patients and plays a significant role in evaluating esophageal healing after preventing harmful effects.Successful LARS improves typical gastroesophageal reflux symptoms in most patients,main-ly by reducing the exposure time to gastric contents in the esophagus.Amelio-ration of the inflammatory response and a recovery response in the esophageal epithelium is expected following the cessation of the noxious attack.AIM To explore the role of inflammatory biomolecules in LARS and assess the time required for esophageal epithelial recovery.METHODS Of 22 patients with LARS(pre-and post/5.8±3.8 months after LARS)and 25 healthy controls(HCs)were included.All subjects underwent 24-h multichannel intraluminal impedance-pH monitoring and upper gastrointestinal endoscopy,during which esophageal biopsy samples were collected using endoscopic tech-niques.Inflammatory molecules in esophageal biopsies were investigated by reverse transcription-polymerase chain reaction and multiplex-enzyme-linked immunosorbent assay.RESULTS Post-LARS samples showed significant increases in proinflammatory cytokines[interleukin(IL)-1β,interferon-γ,C-X-C chemokine ligand 2(CXCL2)],anti-inflammatory cytokines[CC chemokine ligand(CCL)11,CCL13,CCL17,CCL26,CCL1,CCL7,CCL8,CCL24,IL-4,IL-10],and homeostatic cytokines(CCL27,CCL20,CCL19,CCL23,C-CL25,CXCL12,migration inhibitory factor)compared to both HCs and pre-LARS samples.CCL17 and CCL21 levels were higher in pre-LARS than in HCs(P<0.05).The mRNA expression levels of AKT1,fibroblast growth factor 2,HRAS,and mitogen-activated protein kinase 4 were significantly decreased post-LARS vs pre-LARS.CCL2 and epidermal growth factor gene levels were significantly increased in the pre-LARS compared to the HCs(P<0.05).CONCLUSION The presence of proinflammatory proteins post-LARS suggests ongoing inflammation in the epithelium.Elevated homeostatic cytokine levels indicate cell balance is maintained for about 6 months after LARS.The anti-inflam-matory response post-LARS shows suppression of inflammatory damage and ongoing postoperative recovery. 展开更多

BACKGROUND In observational studies,dietary intakes are associated with gastroesophageal re-flux disease(GERD).AIM To conduct a two-sample mendelian randomization(MR)analysis to determine whether those associations are causal.METHODS To explore the relationship between dietary intake and the risk of GERD,we extracted appropriate single nucleotide polymorphisms from genome-wide asso-ciation study data on 24 dietary intakes.Three methods were adopted for data analysis:Inverse variance weighting,weighted median methods,and MR-Egger's method.The odds ratio(OR)and 95%confidence interval(CI)were used to eva-luate the causal association between dietary intake and GERD.RESULTS Our univariate Mendelian randomization(UVMR)results showed significant evidence that pork intake(OR,2.83;95%CI:1.76-4.55;P=1.84×10–5),beer intake(OR,2.70,95%CI:2.00-3.64;P=6.54×10–11),non-oily fish intake(OR,2.41;95%CI:1.49-3.91;P=3.59×10–4)have a protective effect on GERD.In addition,dried fruit intake(OR,0.37;95%CI:0.27-0.50;6.27×10–11),red wine intake(OR,0.34;95%CI:0.25-0.47;P=1.90×10-11),cheese intake(OR,0.46;95%CI:0.39-0.55;P=3.73×10-19),bread intake(OR,0.72;95%CI:0.56-0.92;P=0.0009)and cereal intake(OR,0.45;95%CI:0.36-0.57;P=2.07×10-11)were negatively associated with the risk of GERD.There was a suggestive asso-ciation for genetically predicted coffee intake(OR per one SD increase,1.22,95%CI:1.03-1.44;P=0.019).Multi-variate Mendelian randomization further confirmed that dried fruit intake,red wine intake,cheese intake,and cereal intake directly affected GERD.In contrast,the impact of pork intake,beer intake,non-oily fish intake,and bread intake on GERD was partly driven by the common risk factors for GERD.However,after adjusting for all four elements,there was no longer a suggestive association between coffee intake and GERD.CONCLUSION This study provides MR evidence to support the causal relationship between a broad range of dietary intake and GERD,providing new insights for the treatment and prevention of GERD. 展开更多

BACKGROUND Most endoscopic anti-reflux interventions for gastroesophageal reflux disease(GERD)management are technically challenging to practice with inadequate data to support it utility.Therefore,this study was carried to evaluate the effectiveness and safety newer endoscopic full-thickness fundoplication(EFTP)device along with Argon Plasma Coagulation to treat individuals with GERD.AIM To evaluate the effectiveness and safety newer EFTP device along with Argon Plasma Coagulation to treat individuals with GERD.METHODS This study was a single-center comparative analysis conducted on patients treated at a Noble Institute of Gastroenterology,Ahmedabad,hospital between 2020 and 2022.The research aimed to retrospectively analyze patient data on GERD symptoms and proton pump inhibitor(PPI)dependence who underwent EFTP using the GERD-X system along with argon plasma coagulation(APC).The primary endpoint was the mean change in the total gastroesophageal reflux disease health-related quality of life(GERD-HRQL)score compared to the baseline measurement at the 3-month follow-up.Secondary endpoints encompassed enhancements in the overall GERD-HRQL score,improvements in GERD symptom scores at the 3 and changes in PPI usage at the 3 and 12-month time points.RESULTS In this study,patients most were in Hill Class II,and over half had ineffective esophageal motility.Following the EFTP procedure,there were significant improvements in heartburn and regurgitation scores,as well as GERDHRQL scores(P<0.001).PPI use significantly decreased,with 82.6%not needing PPIs or prokinetics at end of 1 year.No significant adverse events related to the procedures were observed in either group.CONCLUSION The EFTP along with APC procedure shows promise in addressing GERD symptoms and improving patients'quality of life,particularly for suitable candidates.Moreover,the application of a lone clip with APC yielded superior outcomes and exhibited greater cost-effectiveness. 展开更多

BACKGROUND Previous observational studies have shown that the prevalence of gastroesophageal reflux disease(GERD)and Barrett’s esophagus(BE)is associated with socioeconomic status.However,due to the methodological limitations of traditional observational studies,it is challenging to definitively establish causality.AIM To explore the causal relationship between the prevalence of these conditions and socioeconomic status using Mendelian randomization(MR).METHODS We initially screened single nucleotide polymorphisms(SNPs)to serve as proxies for eight socioeconomic status phenotypes for univariate MR analysis.The inverse variance weighted(IVW)method was used as the primary analytical method to estimate the causal relationship between the eight socioeconomic status phenotypes and the risk of GERD and BE.We then collected combinations of SNPs as composite proxies for the eight socioeconomic phenotypes to perform multivariate MR(MVMR)analyses based on the IVW MVMR model.Furthermore,a two-step MR mediation analysis was used to examine the potential mediation of the associations by body mass index,major depressive disorder(MDD),smoking,alcohol consumption,and sleep duration.RESULTS The study identified three socioeconomic statuses that had a significant impact on GERD.These included household income[odds ratio(OR):0.46;95% confidence interval(95%CI):0.31-0.70],education attainment(OR:0.23;95%CI:0.18-0.29),and the Townsend Deprivation Index at recruitment(OR:1.57;95%CI:1.04-2.37).These factors were found to independently and predominantly influence the genetic causal effect of GERD.Furthermore,the mediating effect of educational attainment on GERD was found to be mediated by MDD(proportion mediated:10.83%).Similarly,the effect of educational attainment on BE was mediated by MDD(proportion mediated:10.58%)and the number of cigarettes smoked per day(proportion mediated:3.50%).Additionally,the mediating effect of household income on GERD was observed to be mediated by sleep duration(proportion mediated:9.75%)CONCLUSION This MR study shed light on the link between socioeconomic status and GERD or BE,providing insights for the prevention of esophageal cancer and precancerous lesions. 展开更多
