Abstract
BACKGROUND Previous studies suggested that antireflux mucosectomy (ARMS) is effective in reducing reflux symptoms and total acid exposure, although the mechanism is unknown. Our objective was to investigate the effect of ARMS on reflux parameters and its mechanism of action. METHODS Gastroesophageal reflux disease (GERD) patients with insufficient symptom control despite a twice-daily proton pump inhibitor (PPI) underwent a piecemeal multiband mucosectomy of 50% of the circumference of the esophagogastric junction (EGJ), extending 2 cm into the cardia. The primary end point was the total number of reflux episodes during 24-hour pH-impedance studies. RESULTS 11 patients (8 men; median age 37 [interquartile range (IQR) 32-57] years) were treated, with one patient subsequently lost to follow-up. ARMS reduced the median (IQR) number of total reflux episodes (74 [60-82] vs. 37 [28-66]; P = 0.008) and total acid exposure time (8.7% [6.4%-12.7%] vs. 5.3% [3.5%-6.7%]; P = 0.03). Treatment reduced the median (IQR) number of transient lower esophageal sphincter relaxations (TLESRs) during a 90-minute postprandial period (4 [1-8] vs. 2 [1-4]; P = 0.03) and reflux symptom scores (3.6 [3.6-3.9] vs. 1.6 [0.7-2.7]; P = 0.005). Treatment did not increase the mean (SD) dysphagia scores (8.2 [7.3] vs. 8.5 [6.5]) or change the EGJ distensibility on impedance planimetry (4.4 [2.1] vs. 4.3 [2.2] mm2/mmHg). One delayed post-procedural bleed requiring repeat endoscopy occurred (10%); no strictures developed. CONCLUSION ARMS is an effective treatment option in PPI-refractory GERD, reducing acid exposure, reflux episodes, and symptoms. While its working mechanism could not be explained by a difference in distensibility, a reduction in TLESRs might play a role.

Abstract
OBJECTIVES The endoscopic pressure study integrated system (EPSIS) is a novel diagnostic tool used to evaluate lower esophageal sphincter (LES) function. EPSIS allows the measurement of intragastric pressure (IGP) during gastric insufflation through esophagogastroduodenoscopy (EGD) and records its pressure waveform. This study aimed to assess the usefulness and applicability of EPSIS as an adjunct diagnostic modality for achalasia. METHODS This case-control study was conducted using a database of patients who underwent EGD, barium swallow (BS), high-resolution manometry (HRM), and EPSIS between January 2022 and December 2022. The achalasia (experimental) group (n = 35) consisted of patients with a definitive diagnosis of achalasia. The control group (n = 34) consisted of patients with no abnormalities in EGD, BS, or HRM and no abnormal acid reflux confirmed with 24-h pH-impedance monitoring. EPSIS findings were compared between the two groups and characterized by the waveform pattern (uphill or flat), maximum IGP (IGP-Max), pressure difference, and the gradient of the waveform. RESULTS All patients in the achalasia group showed an uphill pattern, in contrast to 21 patients (61.8%) in the control group. IGP-Max demonstrated the best diagnostic accuracy for achalasia, with a cut-off value of 15.8 mmHg (100% sensitivity, 58.8% specificity, and area under the curve [AUC] 0.78). The pressure gradient also demonstrated good diagnostic accuracy, with a cut-off value of 0.40 mmHg/s (80% sensitivity, 61.8% specificity, and AUC 0.76). CONCLUSION This study demonstrated that EPSIS can be applied as a diagnostic modality in patients with achalasia.

Abstract
Gastro-oesophageal reflux disease (GERD) is a common gastrointestinal disorder in which retrograde flow of gastric content into the oesophagus causes uncomfortable symptoms and/or complications. It has a multifactorial and partially understood pathophysiology. GERD starts in the stomach, where the refluxate material is produced. Following the trajectory of reflux, the failure of the antireflux barrier, primarily the lower oesophageal sphincter and the crural diaphragm, enables the refluxate to reach the oesophageal lumen, triggering oesophageal or extra-oesophageal symptoms. Reflux clearance mechanisms such as primary and secondary peristalsis and the arrival of bicarbonate-rich saliva are critical to prevent mucosal damage. Alterations of the oesophageal mucosal integrity, such as macroscopic oesophagitis or microscopic changes, determine the perception of symptoms. The intensity of the symptoms is affected by peripheral and central neural and psychological mechanisms. In this Review, we describe an updated understanding of the complex and multifactorial pathophysiology of GERD. It is now recognized that different GERD phenotypes have different degrees of reflux, severity of mucosal integrity damage and type, and severity of symptoms. These variations are probably due to the occurrence of a predominant pathophysiological mechanism in each patient. We also describe the main pathophysiological mechanisms of GERD and their implications for personalized diagnosis and management.

Abstract
OBJECTIVES Minimally invasive treatments have been applied for gastroesophageal reflux disease (GERD), but the long-term results are controversial. Antireflux mucosectomy (ARMS) is a simple endoscopic procedure that does not require the insertion of a foreign body. We provide the first report on the long-term results of ARMS. METHODS This was a single-center, single-arm trial, prospective study of 88 patients with proton pump inhibitor (PPI)-refractory GERD who underwent ARMS between June 2012 and June 2017. Primary outcomes were the rates of long-term effectiveness and PPI discontinuation. Secondary outcomes were to compare patients' preoperative background characteristics, questionnaire, and multichannel intraluminal impedance and pH monitoring data to examine the predictive factors of ARMS. The clinical course was reviewed, including the need for additional treatment after ARMS. RESULTS Antireflux mucosectomy produced a long-term effect in 68.3% of the patients, and PPI could be discontinued in 42% of patients. There were significant differences in age, intensity of preoperative symptoms, and acid-related indicators. Forty-five percent (27/60) had reflux hypersensitivity and ARMS provided long-term effectiveness in 81% of these patients. There was no significant difference in subjective symptom assessment between those with short-term and long-term efficacy. Additional treatment was administered in 23% (14/60) and scheduled at 1-2 years' follow-up. CONCLUSIONS Antireflux mucosectomy showed long-term efficacy, and many of the cases with short-term effects were able to maintain them. In addition, ARMS is also effective in patients with reflux hypersensitivity, and provides a treatment option that bridges the gap between surgical and medical treatment.

Abstract
This review examines the temporal association between nocturnal gastro-oesophageal reflux and sleep-arousal cycles. Most nocturnal gastro-oesophageal reflux events occur during the awake cycle, and arousals precede most nocturnal gastro-oesophageal reflux events, indicating that arousal from sleep predisposes to nocturnal gastro-oesophageal reflux. This sheds light on the complex relationship between nocturnal gastro-oesophageal reflux and sleep, and has implications for managing nocturnal gastro-oesophageal reflux symptoms. The appearance of symptoms and the pathophysiology of nocturnal gastro-oesophageal reflux are influenced by sleep hygiene, sleep disturbances and the misalignment of circadian rhythms. Nocturnal gastro-oesophageal reflux and its related sleep disorders are prevalent and negatively impact the quality of life. There is conflicting evidence on whether nocturnal gastro-oesophageal reflux and sleep disturbances are causally linked, and whether sleep disturbances drive nocturnal gastro-oesophageal reflux. Poor sleep quality increases oesophageal hypersensitivity and overall acid exposure. The nocturnal gastro-oesophageal reflux is linked to the more severe forms of gastro-oesophageal reflux disease, especially with atypical/extra-oesophageal manifestations and complications of mucosal damage such as oesophagitis and stricture, Barret's oesophagus, and oesophageal adenocarcinoma. This review highlights the role of sleep problems in presenting nocturnal gastro-oesophageal reflux, and the potential benefits of treating sleep disturbances in enhancing patient care and quality of life.

Abstract
Background Objective functional assessment of esophagogastric anastomosis in patients who underwent proximal gastrectomy with the hinged double flap method for gastric cancer has not been well investigated. This study aimed to perform a functional analysis of reconstruction using high-resolution impedance manometry (HRIM). Materials and methods The authors enroled 25 patients who underwent proximal gastrectomy for gastric cancer between May 2015 and April 2020 and subsequently underwent HRIM postoperatively. Eligible questionnaires [Postgastrectomy Syndrome Assessment Scale-37 (PGSAS-37)] were retrieved from 16 patients. The association between HRIM data and PGSAS-37 was analyzed. Results The amplitudes of distal oesophageal peristaltic waves, contractile front velocity, and distal latency assessed by HRIM were almost normal after surgery. Most patient's lower oesophageal sphincter (LES) resting pressure created by the hinged double flap was within normal limits. Conversely, LES residual pressure values during swallowing-induced relaxation were abnormally high in most patients, and the lower the values, the more severe the reflux and diarrhoea symptoms (P=0.038, P=0.041, respectively). In addition, even when the integrated relaxation pressure (IRP) was normal, lower values corresponded to more severe reflux symptoms (P=0.020). The required LES pressure may be higher after proximal gastrectomy because of the relatively higher intragastric pressure due to the reduced volume of the remnant stomach. This also suggests that swallowing-induced relaxation of the LES was considered a trigger for oesophageal reflux in post-proximal gastrectomy patients. Conclusion LES residual pressure and IRP values in HRIM correlated with reflux symptoms in patients after proximal gastrectomy.

Abstract
Abdominal bloating (AB) is a common symptom among patients with gastroesophageal reflux disease (GERD); however, in clinical practice, its prevalence is likely underestimated due to the lack of objective tools to measure its frequency and severity. It is associated with dissatisfaction and worse quality of life, but data on its prevalence before and after mechanical control of GERD (i.e. fundoplication, magnetic sphincter augmentation, and antireflux mucosectomy) are lacking. To assess and determine the pre- and postoperative prevalence and severity of AB among patients with GERD, we conducted a structured literature search using MeSH and free-text terms in MEDLINE (via Pubmed), EMBASE, and Taylor & Francis Online between January 1977 and October 2022. Fifteen articles reporting the prevalence or severity of AB using quality-of-life questionnaires before or after antireflux surgery (ARS) were included. Overall, a high prevalence of AB before ARS was found. A decline in the prevalence and severity of AB was documented postoperatively in most cases independent of the surgical approach. Among surgical approaches, a complete fundoplication had the highest reported postoperative AB. Overall, patients reported less severe and less frequent AB after ARS than before. The traditional belief that postoperative bloating is a sequela of ARS should be reevaluated.

Abstract
BACKGROUND The last 40 years have seen a remarkable change in our understanding of reflux disease. SUMMARY These changes encompass disease definition and impact, pathophysiology, diagnostic testing, regulatory oversight of clinical trials, pharmacotherapy, endoscopic, and surgical treatment. We have also seen a number of promising therapies fail. KEY MESSAGES The future holds the promise of further advances. Adaptive artificial intelligence will take over diagnostics in manometry and pH impedance testing and patient-driven outcomes may be changed by interactions with artificial intelligence rather than humans. Changes in chip technology will allow higher resolution chips to be carried on smaller devices making extra-esophageal areas where reflux may play a role more accessible to prolonged observation and testing.

Abstract
BACKGROUND Dysphagia is the most common complaint after magnetic sphincter augmentation (MSA), with nearly one-third of patients requiring at least one dilation following MSA. A subset of patients require frequent dilations, but there is a paucity of data on the characteristics of this population. This study aimed to identify predictors of the need for frequent dilations within the first year after implant and to assess these patients' outcomes. METHODS This is a retrospective review of prospectively collected data of patients who underwent MSA over an 8-year period. Frequent dilations were defined as 2 or more dilations within 1 year of surgery. Patients completed baseline and 1-year postoperative GERD-HRQL questionnaires and objective physiology testing. Baseline demographic, clinical characteristics, and objective testing data were compared between patients who did and did not require frequent dilations. RESULTS A total of 697 (62.7% female) patients underwent MSA, with 62 (8.9%) patients requiring frequent dilation. At a mean (SD) of 12.3 (3.4) months follow-up, the frequent dilation group had higher median GERD-HRQL total scores (21.0 vs. 5.0, p < 0.001), PPI use (20.8% vs.10.1%, p = 0.023), dissatisfaction (46.7% vs. 11.6%, p < 0.001), and device removal (25.8% vs. 2.2%, p < 0.001) rates. Acid normalization was comparable (p = 0.997). Independent predictors of frequent dilation included preoperative odynophagia (OR 2.85; p = 0.001), IRP > 15 mmHg (OR 2.88; p = 0.006), and > 30% incomplete bolus clearance (OR 1.94; p = 0.004). At a mean (SD) of 15.7 (10.7) months, 28 (45.1%) patients underwent device removal after frequent dilation. Independent predictors of device removal after frequent dilation within 5 years of surgery were preoperative odynophagia (OR 7.18; p = 0.042), LES resting pressure > 45 mmHg (OR 28.5; p = 0.005), and ≥ 10% failed swallows (OR 23.5; p < 0.001). CONCLUSIONS The need for frequent dilations after MSA is a marker for poor symptom control, dissatisfaction, and device removal. Patients with preoperative odynophagia, high LES pressures, and poor esophageal motility should be counseled of their risk for these poor outcomes.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition that is on the rise. Obesity is one risk factor that has increased in parallel with the rise of GERD. Typical symptoms include heartburn, regurgitation, dysphagia, cough, and chest pain. Patients with typical symptoms are empirically treated with proton pump inhibitors (PPIs). If the diagnosis is not clear, further evaluation is performed with endoscopy, pH monitoring, and esophageal manometry. Untreated GERD increases the risk of esophagitis, esophageal stricture, Barrett's esophagus, and esophageal adenocarcinoma. Treatment begins with lifestyle modification and medical therapy. If these fail, surgical and endoscopic surgical techniques are available, to provide treatment, symptom relief, and reduce long-term PPI use.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is an effective intervention for achalasia, but GERD is a major postoperative adverse event. This study aimed to characterize post-POEM GERD and identify preoperative or technical factors impacting development or severity of GERD. STUDY DESIGN This is a retrospective review of patients who underwent POEM at our institution. Favorable outcome was defined as postoperative Eckardt score of 3 or less. Subjective GERD was defined as symptoms consistent with reflux. Objective GERD was based on a DeMeester score greater than 14.7 or Los Angeles grade C or D esophagitis. Severe GERD was defined as a DeMeester score greater than 50.0 or Los Angeles grade D esophagitis Preoperative clinical and objective data and technical surgical elements were compared between those with and without GERD. Multivariate logistic analysis was performed to identify factors associated with each GERD definition. RESULTS A total of 183 patients underwent POEM. At a mean ± SD follow-up of 21.7 ± 20.7 months, 93.4% achieved favorable outcome. Subjective, objective, and severe objective GERD were found in 38.8%, 50.5%, and 19.2% of patients, respectively. Of those with objective GERD, 24.0% had no reflux symptoms. Women were more likely to report GERD symptoms (p = 0.007), but objective GERD rates were similar between sexes (p = 0.606). The independent predictors for objective GERD were normal preoperative diameter of esophagus (odds ratio [OR] 3.4; p = 0.008) and lower esophageal sphincter (LES) pressure less than 45 mmHg (OR 1.86; p = 0.027). The independent predictors for severe objective GERD were LES pressure less than 45 mmHg (OR 6.57; p = 0.007) and obesity (OR 5.03; p = 0.005). The length of esophageal or gastric myotomy or indication of procedure had no impact on the incidence or severity of GERD. CONCLUSION The rate of pathologic GERD after POEM is higher than symptomatic GERD. A nonhypertensive preoperative LES is a predictor for post-POEM GERD. No modifiable factors impact GERD after POEM.

Shiota S, Shibata A, Horinouchi N, Yamamoto K, Miyazaki E. Lifestyle Factors Associated With Erosive Esophagitis in Japanese Individuals With and Without Obesity Undergoing Health Checkups. J Prim Care Community Health 2023; 14:21501319231205383. [PMID: 37846060 PMCID: PMC10583521 DOI: 10.1177/21501319231205383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 09/15/2023] [Accepted: 09/18/2023] [Indexed: 10/18/2023] Open
Abstract
BACKGROUND Several lifestyle factors have been reported to be associated with erosive esophagitis (EE). Many studies examined the associated factors for EE independent of obesity. However, lifestyle factors associated with EE might differ depending on sex or the presence of obesity. This study thus aimed to investigate the lifestyle risk factors for EE stratified by obesity and sex. METHODS A cross-sectional survey was conducted among Japanese people who underwent an annual health checkup at the Oita Health Checkup Center between 2019 and 2021. Multivariate analysis was performed to determine the factors associated with EE in participants stratified by sex and the presence of obesity. RESULTS EE was diagnosed in 676 of 5240 participants (12.9%) who were analyzed, and occurred most often in males (601 cases). The percentage of obesity based on body mass index was significantly higher among EE than non-EE participants (50.3% and 26.5%, P < .001). In obese males, eating just before bedtime (OR = 1.34, 95% CI 1.01-1.78) and hiatal hernia (OR = 3.42, 95% CI 2.57-4.54) were significantly associated with EE in multivariate analysis. In non-obese males, current smoking (OR = 1.48, 95% CI 1.07-2.04), alcohol consumption of 40 to 60 g/day (OR = 1.60, 95% CI 1.11-2.30), and hiatal hernia (OR = 3.63, 95% CI 2.79-4.73) were significantly associated with EE. CONCLUSIONS We found that factors associated with EE were different between obese and non-obese males. In obese males, avoiding going to bed within 2 h after dinner might contribute to preventing the occurrence of EE. In non-obese males, prevention of obesity, quitting smoking, and avoiding heavy alcohol consumption might be important for preventing the development of EE.

Abstract
Background: Laparoscopic sleeve gastrectomy (LSG) is associated with the long-term development of gastroesophageal reflux disease (GERD). Recent studies on LSG with fundoplication showed a lower rate of postoperative GERD than LSG alone; however, there is a lack of objective instrumental data in the literature. This study aimed to evaluate whether and how fundoplication associated with Sleeve Gastrectomy affects the esophagogastric physiology. Materials and Methods: This prospective observational study included 20 patients with morbid obesity, GERD, and lower esophageal sphincter (LES) hypotonia. All the patients underwent LSG with Rossetti fundoplication. High-resolution manometry was performed pre- and postoperatively. All the patients completed the 6 months follow-up. Results: The fundoplication increased LES tone in all patients. The increase in the LES tone was statistically significant (330% increase). The integrated relaxation pressure and the distal contractile integral both increased accordingly, indicating an increased esophageal effort to pass through the modified esophagogastric junction. Conclusion: Rossetti fundoplication associated with LSG increased LES tone and decreased the chance of developing long-term GERD after LSG.

Abstract
STUDY OBJECTIVES To objectively characterize (1) the relationship between gastroesophageal reflux disease (GERD) and sleep quality, and (2) the influence of sleep position on this relationship, using in-laboratory polysomnography. METHODS We retrospectively analyzed first-night diagnostic in-laboratory polysomnography data for 3411 patients (median age 55 years; 48% male). Medication use and medical condition data were obtained through self-reported questionnaires. Associations between sleep quality and the presence of GERD, and the influence of sleep position on these associations, were analyzed using multivariable linear regression models. RESULTS After adjusting for age, sex, body mass index, and relevant comorbidities, GERD was associated with a 3.0% decrease in sleep efficiency, 8.8-minute increase in wake after sleep onset, 24.4-minute increase in rapid eye movement (REM) latency, 13.4-minute decrease in total sleep time, 1.4% decrease in %REM sleep, and 1.5% increase in %N3 sleep. Having both GERD and the majority of sleep on the right side was associated with an 8.6% decrease in sleep efficiency, 27.5-minute increase in wake after sleep onset, 35.6-minute decrease in total sleep time, 2.1% decrease in %REM sleep, and 3.5% increase in %N3 sleep. Having both GERD and the majority of sleep on the left side was associated with an 8.7-minute increase in sleep onset latency. CONCLUSIONS GERD is associated with an impairment in objective sleep quality. These associations were more pronounced in right-sided sleep and mostly ameliorated in left-sided sleep. Physicians should recognize the potential for poor sleep quality in patients with GERD and the effect of body position on this relationship. CITATION Gurges P, Murray BJ, Boulos MI.

[PMID: 35692910 PMCID: PMC9187419 DOI: 10.1055/a-1790-6141] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2021] [Accepted: 12/21/2021] [Indexed: 11/18/2022] Open
Abstract
Background and study aims The endoscopic pressure study integrated system (EPSIS), a novel diagnostic tool for gastroesophageal reflux disease (GERD), allows evaluation of the anti-reflux barrier using endoscopy by monitoring the intragastric pressure (IGP) during insufflation. In this study, we evaluated the association between EPSIS results and lower esophageal sphincter (LES) function measured by high-resolution manometry (HRM) to elucidate whether EPSIS can evaluate the LES function. Patients and methods A retrospective, single-center study of patients with GERD symptoms who underwent endoscopy, pH-impedance monitoring, EPSIS, and HRM was conducted. The primary outcome was basal LES pressure and the secondary outcomes were end-respiratory LES pressure and integrated relaxation pressure (IRP). As EPSIS parameters, the following were measured: 1) pressure difference (mmHg), the difference between maximum and basal IGP; and 2) pressure gradient (mmHg/s), calculated by dividing pressure difference by the insufflating time. Pressure difference < 4.7 mmHg or pressure gradient < 0.07 mmHg/s was defined as an EPSIS GERD pattern. Results Forty-seven patients (median age: 53 years, 37 female) were analyzed. Pressure difference and pressure gradient significantly correlated with basal LES pressure (ρ = 0.29; P = 0.04 and ρ = 0.29; P = 0.04). Patients with EPSIS GERD pattern showed significantly lower basal LES pressure [13.2 (4.8-26.6) vs 25.3 (10.4-66.7) mmHg, P = 0.002], lower end-respiratory LES pressure [8.5 (1.1-15.9) vs 15.5 (1.9-43.9) mmHg, P = 0.019] and lower IRP [5.9 (1.0-12.0) vs 9.8 (1.3-17.8) mmHg, P = 0.020]. Conclusions This study showed a close association between EPSIS results and LES pressures measured by HRM. This indicates that EPSIS can evaluate the LES function during endoscopy and endorse the role of EPSIS as a diagnostic tool for GERD.

Abstract
Background and study aims Anti-reflux mucosectomy (ARMS) is an emerging endoscopic treatment for refractory gastroesophageal reflux disease (GERD). We conducted a systematic review and meta-analysis to evaluate the safety and efficacy ARMS in refractory GERD. Methods A comprehensive search of multiple databases (through March 2020) was performed to identify studies that reported outcomes of ARMS for refractory GERD. Outcomes assessed included technical success, clinical response, and adverse events (AEs). Clinical response was defined as discontinuation (complete) or reduction (partial) of proton pump inhibitors post-ARMS at follow up. Results A total of 307 patients (mean age 46.9 [8.1] years, 41.5 % females) were included from 10 studies. The technical success and clinical response rates were 97.7 % (95 % confidence interval [CI], 94.6-99.0) and 80.1 % (95 % CI, 61.6-91.0), respectively. The pooled rate of complete and partial clinical response was 65.3 % (95 % CI, 51.4-77.0) and 21.5 % (95 % CI, 14.2-31.2), respectively. The rate of AEs was 17.2 % (95 % CI, 13.1-22.2) with most common AE being dysphagia/esophageal stricture followed by bleeding with rates of 11.4 % and 5.0 %, respectively. GERD health-related quality of life (GERD-HRQL) (mean difference [MD] = 14.9, P < 0.001), GERD questionnaire (GERD-Q) (MD = 4.85, P < 0.001) and mean acid exposure time (MD = 2.39, P = 0.01) decreased significantly post-ARMS as compared to pre-procedure. There was no difference in terms of clinical response and AEs between ARMS and ARMS with banding on subgroup analysis. Conclusions ARMS is a safe and effective procedure for treatment of refractory GERD with high rates of clinical response, acceptable safety profile and significant improvement in GERD-related quality of life. Prospective studies are needed to validate our findings.

Ca 2+ signalling in interstitial cells of Cajal contributes to generation and maintenance of tone in mouse and monkey lower esophageal sphincters. J Physiol 2022; 600:2613-2636.

Abstract
KEY POINTS The lower esophageal sphincter (LES) generates contractile tone preventing reflux of gastric contents into the esophagus. LES smooth muscle cells (SMCs) display depolarized membrane potentials facilitating activation of L-type Ca2+ channels. Interstitial cells of Cajal (ICC) express Ca2+ -activated Cl- channels encoded by Ano1 in mouse and monkey LES. Ca2+ signaling in ICC activates ANO1 currents in ICC. ICC displayed spontaneous Ca2+ transients in mice from multiple firing sites in each cell and no entrainment of Ca2+ firing between sites or between cells. Inhibition of ANO1 channels with a specific antagonist caused hyperpolarization of mouse LES and inhibition of tone in monkey and mouse LES muscles. Our data suggest a novel mechanism for LES tone in which Ca2+ transient activation of ANO1 channels in ICC generates depolarizing inward currents that conduct to SMCs to activate L-type Ca2+ currents, Ca2+ entry and contractile tone. ABSTRACT The lower esophageal sphincter (LES) generates tone and prevents reflux of gastric contents. LES smooth muscle cells (SMCs) are relatively depolarized, facilitating activation of Cav 1.2 channels to sustain contractile tone. We hypothesised that intramuscular interstitial cells of Cajal (ICC-IM), through activation of Ca2+ -activated-Cl- channels (ANO1), set membrane potentials of SMCs favorable for activation of Cav 1.2 channels. In some gastrointestinal muscles, ANO1 channels in ICC-IM are activated by Ca2+ transients, but no studies have examined Ca2+ dynamics in ICC-IM within the LES. Immunohistochemistry and qPCR were used to determine expression of key proteins and genes in ICC-IM and SMCs. These studies revealed that Ano1 and its gene product, ANO1 are expressed in c-Kit+ cells (ICC-IM) in mouse and monkey LES clasp muscles. Ca2+ signaling was imaged in situ, using mice expressing GCaMP6f specifically in ICC (Kit-KI-GCaMP6f). ICC-IM exhibited spontaneous Ca2+ transients from multiple firing sites. Ca2+ transients were abolished by CPA or caffeine but were unaffected by tetracaine or nifedipine. Maintenance of Ca2+ transients depended on Ca2+ influx and store reloading, as Ca2+ transient frequency was reduced in Ca2+ free solution or by Orai antagonist. Spontaneous tone of LES muscles from mouse and monkey was reduced ∼80% either by Ani9, an ANO1 antagonist or by the Cav 1.2 channel antagonist nifedipine. Membrane hyperpolarisation occurred in the presence of Ani9. These data suggest that intracellular Ca2+ activates ANO1 channels in ICC-IM in the LES. Coupling of ICC-IM to SMCs drives depolarization, activation of Cav 1.2 channels, Ca2+ entry and contractile tone. Abstract figure legend Proposed mechanism for generation of contractile tone in the lower esophageal sphincter (LES). Interstitial cells of Cajal (ICC) in the LES generate spontaneous, stochastic Ca2+ transients via Ca2+ release from the endoplasmic reticulum (ER). The Ca2+ transients activate ANO1 Cl- channels causing Cl- efflux (inward current). ANO1 currents have a depolarizing effect on ICC (+++s inside membrane) and this conducts through gap junctions (GJ) to smooth muscle cells (SMCs). Input from thousands of ICC results in depolarized membrane potentials (-40 to -50 mV) which is within the window current range for L-type Ca2+ channels. Activation of these channels causes Ca2+ influx, activation of contractile elements (CE) and development of tonic contraction. This article is protected by copyright. All rights reserved.

Abstract
BACKGROUND Hiatal hernia is clinically important because it impairs the protective mechanism that prevents gastroesophageal reflux-induced injury. Diagnosing hiatal hernia is more important in neurologically impaired children because hiatal hernia-induced gastroesophageal reflux often causes severe complications such as aspiration pneumonia or malnutrition. We aimed to evaluate the patient characteristics and early predictors of hiatal hernia in neurologically impaired children. METHODS We retrospectively investigated 97 neurologically impaired children who underwent esophagogastroduodenoscopy and upper gastrointestinal series between March 2004 and June 2019. Demographic and clinical characteristics, as well as endoscopic and radiological findings, were statistically analyzed. RESULTS Of the 97 children recruited, 22 (22.7%) had hiatal hernia. When comparing the non-hiatal hernia group with the hiatal hernia group, neurological disease longer than 6 months (odds ratio 10.9, 95% confidence interval 1.2-96.5), wasting (odds ratio 4.6, 95% confidence interval 1.3-16.3), enteral tube feeding (odds ratio 9.2, 95% confidence interval 1.6-53.0), and history of aspiration pneumonia (odds ratio 6.5, 95% confidence interval 1.2-34.5) were identified as early predictors of hiatal hernia. CONCLUSIONS Timely identification of predictors of developing hiatal hernia in neurologically impaired children is important for early diagnostic confirmation to initiate optimal medical or surgical treatment of hiatal hernia to avoid serious complications such as aspiration pneumonia and malnutrition.

Abstract
In Japan, with the increasing prevalence of gastroesophageal reflux disease (GERD) and growing public interest, the Japanese Society of Gastroenterology issued Evidence-based Clinical Practice Guidelines for GERD (1st edition) in 2009 and a revised 2nd edition in 2015. A number of studies on GERD were subsequently conducted in Japan and abroad, and vonoprazan, a potassium-competitive acid blocker (P-CAB), became available for the first time in Japan in February 2015. The revised 3rd edition (Japanese edition), which incorporates new findings and information, was published in April 2021. These guidelines are summarized herein, particularly sections related to the treatment of GERD. The important clinical issues addressed in the present revision are (i) the introduction of treatment algorithms that classify GERD into reflux esophagitis and non-erosive reflux disease, (ii) the clarification of treatment algorithms based on to the severity of reflux esophagitis, and (iii) the positioning of vonoprazan in the treatment for GERD. The present guidelines propose vonoprazan as the initial/maintenance treatment for severe reflux esophagitis. They also recommend vonoprazan or PPI as an initial treatment for mild reflux esophagitis and recommended PPI and proposed vonoprazan as maintenance treatment. These updated guidelines offer the best clinical strategies for GERD patients in Japan and hope that they will be of global use for the diagnosis and treatment for GERD.

Abstract
Achalasia is the prototypical obstructive motor disorder diagnosed using HRM, but non-achalasia motor disorders are often identified in symptomatic patients. The clinical relevance of these disorders are assessed using ancillary HRM maneuvers (multiple rapid swallows, rapid drink challenge, solid swallows) that augment the standard supine HRM evaluation by challenging peristaltic function. Finding obstructive motor physiology in non-achalasia motor disorders may raise the option of invasive management akin to achalasia. Certain non-achalasia disorders, particularly hypermotility disorders, may manifest as epiphenomena seen with esophageal hypersensitivity. Symptomatic management is offered for superimposed reflux disease, psychological disorders, functional esophageal disorders, and behavioral disorders.

Abstract
BACKGROUND The prevalence of duodenogastroesophageal reflux (DGER) and its effect on symptoms and oesophageal lesions in gastroesophageal reflux disease (GERD) is unclear. AIMS To conduct a systematic review to determine the prevalence of DGER among patients with GERD, the effect of DGER on symptoms and oesophageal lesions, and the treatment of DGER. METHODS We searched Pubmed and MEDLINE for full text, English language articles until October 2020 that evaluated DGER prevalence among patients with GERD, the effect of DGER on symptoms and oesophageal lesions, and the treatment of DGER. RESULTS We identified 3891 reports and included 35 which analysed DGER prevalence in GERD, 15 which evaluated its effect in non-erosive reflux disease (NERD), 17 on erosive oesophagitis, 23 in Barrett's, and 13 which evaluated the treatment of DGER. The prevalence of DGER, when evaluated by Bilitec, among all GERD patients ranged from 10% to 97%, in NERD 10%-63%, in erosive oesophagitis 22%-80% and in Barrett's 50%-100%. There were no differences in the presence or degree of DGER among patients who were asymptomatic or symptomatic on proton pump inhibitors (PPI). The most commonly evaluated treatments for DGER were PPIs and DGER reduced post-PPI therapy in all studies. CONCLUSIONS The prevalence of DGER increased with more advanced oesophageal lesions and did not explain persisting symptoms among patients taking PPI therapy. PPIs appear to be effective in the treatment of DGER. DGER remains an important consideration in patients with GERD and future therapies deserve more study.

Abstract
Background/Aims A diagnosis of gastroesophageal reflux disease is challenging in patients who have reflux symptoms but do not respond to proton pump inhibitors nor have reflux esophagitis and hiatal hernia (HH) on endoscopy. This study examined the predictive role of the endoscopic findings, including the flap valve grade for pathologic acid exposure (PAE) to establish an endoscopic prediction model in patients with neither reflux esophagitis nor HH. Methods Five hundred seventy-eight patients who underwent upper endoscopy and 24 hours pH monitoring for reflux esophageal symptoms without evidence of reflux esophagitis and HH were analyzed. The gastroesophageal flap valve (GEFV), esophageal metaplasia, and chronic atrophic gastritis were assessed. The association between the endoscopic parameters and PAE was evaluated. Results Four hundred ninety-four patients were enrolled. The most common complaint was chest discomfort (42.3%) followed by globus (31.8%), dysphagia (7.9%), and heartburn (7.7%). PAE was present in 43 patients (8.7%). Multivariable analysis revealed PAE to be associated with the GEFV grade (p<0.001) and inversely associated with the chronic atrophic gastritis grade (p=0.005). Using these features, a predictive model was established and showed an area under the receiver operating characteristic curve of 0.705 (95% CI 0.619-0.790). The cutoff value of 12.0 had a sensitivity and specificity of 44.0% and 84.0%, respectively. Conclusions A loosened GEFV is associated with a risk of PAE in patients with neither reflux esophagitis nor HH, while atrophic gastritis is preventive. On the other hand, the endoscopic predictive model revealed a low sensitivity for detecting PAE. Thus, reflux testing needs to be performed further when gastroesophageal reflux disease is suspected, even without endoscopic evidence.

Abstract
Gastro-oesophageal reflux disease (GERD) is a common disorder in adults and children. The global prevalence of GERD is high and increasing. Non-erosive reflux disease is the most common phenotype of GERD. Heartburn and regurgitation are considered classic symptoms but GERD may present with various atypical and extra-oesophageal manifestations. The pathophysiology of GERD is multifactorial and different mechanisms may result in GERD symptoms, including gastric composition and motility, anti-reflux barrier, refluxate characteristics, clearance mechanisms, mucosal integrity and symptom perception. In clinical practice, the diagnosis of GERD is commonly established on the basis of response to anti-reflux treatment; however, a more accurate diagnosis requires testing that includes upper gastrointestinal tract endoscopy and reflux monitoring. New techniques and new reflux testing parameters help to better phenotype the condition. In children, the diagnosis of GERD is primarily based on history and physical examination and treatment vary with age. Treatment in adults includes a combination of lifestyle modifications with pharmacological, endoscopic or surgical intervention. In refractory GERD, optimization of proton-pump inhibitor treatment should be attempted before a series of diagnostic tests to assess the patient's phenotype.

Abstract
Gastroesophageal reflux disease (GERD) is steadily increasing in incidence and now affects 18% to 28% of the population in the United States. A thorough understanding of the pathophysiology underlying this disease is necessary to improve the current standard of care. Most GERD pathophysiology models focus on the lower esophageal sphincter (LES) as the key element which prevents esophageal reflux. More recent research has highlighted the crural diaphragm (CD) as an additional critical component of the GERD barrier. We now know that the CD actively relaxes when the distal esophagus is distended and contracts when the stomach is distended. Crural myotomy in animal models increases esophageal acid exposure, highlighting the CD's vital role. There are also multiple physiological studies in patients with symptomatic hiatal hernia that demonstrate CD dysfunction is associated with GERD. Finally, computer models integrating physiological data predict that the CD and the LES each contribute roughly 50% to the GERD barrier. This more robust understanding has implications for future procedural management of GERD. Specifically, effective GERD management mandates repair of the CD and reinforcement of the LES. Given the high rate of hiatal hernia recurrences, it seems that novel antireflux procedures should target this essential component of the GERD barrier. Future research should focus on methods to maintain crural integrity, decrease hiatal hernia recurrence, and improve long-term competency of the GERD barrier.

Abstract
BACKGROUND Erosive esophagitis (EE) is strongly associated with metabolic syndrome (MS), but is not always recognized in individuals with MS and the prevalence of EE in individuals with non-MS is not low. AIM To examine the differences in clinical factors associated with EE at various stages of MS, as well as the differences in metabolites between subjects with MS, with and without EE. METHODS A total of 7,097 persons who underwent health checkups including esophagogastroduodenoscopy were analyzed. We examined the differences in clinical factors for EE among subjects with non-MS, pre-MS, and MS and compared metabolites between 34 subjects with MS, with and without EE. RESULTS EE prevalence was significantly higher in the MS and pre-MS groups than in the non-MS group (p < 0.001). EE severity was higher in the MS group than in the pre-MS and non-MS groups (p < 0.001). In the non-MS group, there were significant differences between subjects with and without EE with respect to Helicobacter pylori (H. pylori) and smoking. In the pre-MS and MS groups, there were significant differences in H. pylori, hiatal hernia, and drinking in those with and without EE. The levels of glutamine, hypoxanthine, and lactic acid metabolites were significantly different between subjects with MS, with and without EE (all p < 0.05). CONCLUSION Although H. pylori and lifestyle factors such as smoking and drinking are important for EE, differences in these factors should be considered at various stages of MS. Additionally, several metabolites may be involved in the development of EE in MS.

Abstract
OBJECTIVES Some patients with gastroesophageal reflux disease (GERD) are refractory to proton pump inhibitor (PPI) therapy. Anti-reflux mucosectomy (ARMS) is a minimally invasive endoscopic procedure for treatment of GERD. In this study, we retrospectively evaluated the outcomes of ARMS performed in patients with PPI-refractory GERD at our institution. METHODS A total of 109 patients with PPI-refractory GERD who underwent ARMS were retrospectively reviewed. Pre- and post-ARMS questionnaire scores, acid exposure time (AET), DeMeester score, proximal extent, and PPI discontinuation rate were compared. RESULTS There was a significant improvement in the symptom score (P < 0.01) and 40-50% of patients were able to discontinue PPI after ARMS. In patients who were followed up for 3 years, sustained improvement in subjective symptoms was observed. AET and DeMeester score significantly improved after ARMS (P < 0.01); however, there was no significant improvement in proximal extent (P = 0.0846). CONCLUSIONS Anti-reflux mucosectomy is an effective minimally invasive therapy for patients with PPI-refractory GERD. The therapeutic efficacy is attributable to suppression of acid backflow due to contraction of the scar tissue in cardia.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition and impairs the quality of life for millions of patients, accounts for considerable health care spending, and is a primary risk factor for esophageal adenocarcinoma. There have been substantial advances in understanding the pathogenesis of GERD and its complications and much progress in diagnosis and management of GERD; however, these have not been comprehensively discussed in the recent radiology literature. Understanding the role of imaging in GERD and its complications is important to aid in multidisciplinary treatment of GERD. GERD results from prolonged or recurrent reflux of gastric contents into the esophagus. Common symptoms include heartburn or regurgitation. Prolonged reflux of gastric contents into the esophagus can cause erosive esophagitis. Over time, the inflammatory response related to esophagitis can lead to deposition of fibrous tissue and development of strictures. Alternatively, the esophageal mucosa can undergo metaplasia (Barrett esophagus), a precursor to dysplasia (which can lead to adenocarcinoma). Conventional barium esophagography has long been considered the primary imaging modality for the esophagus, and the fluoroscopic findings for diagnosis of GERD have been well established. Multimodality imaging has a clear role in detection and assessment of the complications of GERD, specifically reflux esophagitis and Barrett esophagus; differentiation of benign and malignant strictures; and detection, staging, and posttreatment surveillance of esophageal adenocarcinoma. Given the dramatic changes in utilization of abdominal imaging during the past 2 decades, with significantly declining volume of fluoroscopic procedures and concomitant increase in CT and MRI studies, it is crucial that modern radiologists appreciate the value of barium esophagography in the workup of GERD and recognize the key imaging features of GERD and its complications at CT and MRI.

Abstract
INTRODUCTION Uncontrolled results suggest that diaphragmatic breathing (DB) is effective in gastroesophageal reflux disease (GERD) but the mechanism of action and rigor of proof is lacking. This study aimed to determine the effects of DB on reflux, lower esophageal sphincter (LES), and gastric pressures in patients with upright GERD and controls. METHODS Adult patients with pH proven upright GERD were studied. During a high-resolution impedance manometry, study patients received a standardized pH neutral refluxogenic meal followed by LES challenge maneuvers (Valsalva and abdominal hollowing) while randomized to DB or sham. After that, patients underwent 48 hours of pH-impedance monitoring, with 50% randomization to postprandial DB during the second day. RESULTS On examining 23 patients and 10 controls, postprandial gastric pressure was found to be significantly higher in patients compared with that in controls (12 vs 7 mm Hg, P = 0.018). Valsalva maneuver produced reflux in 65.2% of patients compared with 44.4% of controls (P = 0.035). LES increased during the inspiratory portion of DB (42.2 vs 23.1 mm Hg, P < 0.001) in patients and healthy persons. Postprandial DB reduced the number of postprandial reflux events in patients (0.36 vs 2.60, P < 0.001) and healthy subjects (0.00 vs 1.75, P < 0.001) compared with observation. During 48-hour ambulatory study, DB reduced the reflux episodes on day 2 compared with observation on day 1 in both the patient and control groups (P = 0.049). In patients, comparing DB with sham, total acid exposure on day 2 was not different (10.2 ± 7.9 vs 9.4 ± 6.2, P = 0.804). In patients randomized to DB, esophageal acid exposure in a 2-hour window after the standardized meal on day 1 vs day 2 reduced from 11.8% ±6.4 to 5.2% ± 5.1, P = 0.015. DISCUSSION In patients with upright GERD, DB reduces the number of postprandial reflux events pressure by increasing the difference between LES and gastric pressure. These data further encourage studying DB as therapy for GERD.

Abstract
OBJECTIVES The endoscopic pressure study integrated system (EPSIS) is a novel diagnostic tool for gastroesophageal reflux disease (GERD) by monitoring intragastric pressure (IGP). Evaluation of the lower esophageal sphincter (LES) function may be achieved endoscopically by utilizing this newly developed diagnostic tool. This study aimed to evaluate the association between EPSIS results and gastroesophageal reflux-related diseases, e.g., erosive esophagitis (EE) and Barrett's esophagus (BE). METHODS This was a retrospective, single-center study. All patients who underwent EPSIS between November 2016 and July 2018 were included. EPSIS was performed during esophagogastroduodenoscopy with a dedicated electronic device and a through-the-scope catheter. The maximum IGP (IGP-max) and IGP waveform pattern (flat or uphill) were recorded with this system. Evaluation of an EE and BE was based on the Los Angeles classification and Prague classification, respectively. RESULTS A total of 104 patients were enrolled; 29 (28%) had EE and 42 (40%) had BE. Patients with EE had lower IGP-max values (16.0 vs 18.8 mmHg, P = 0.01) and an EPSIS flat pattern was seen more frequently (82.8% vs 37.3%, P < 0.001). Similarly, patients with BE displayed a lower IGP-max (15.7 vs 19.6 mmHg, P < 0.001) and presented with an EPSIS flat pattern in a higher proportion (69% vs 37.1%, P < 0.001). These differences remained significant on multivariate analysis. CONCLUSIONS The EPSIS, as a novel diagnostic tool, was shown to exhibit a relation with EE and BE, implying that EPSIS is a promising modality to evaluate gastroesophageal reflux-related diseases and LES function endoscopically.

Abstract
The incidence of gastroesophageal reflux disease (GERD) remains on the rise. Pathophysiology of GERD is multifactorial, revolving around an incompetent esophagogastric junction as an antireflux barrier, with other comorbid conditions contributing to the disease. Proton pump inhibitors remain the most common treatment of GERD. Endoscopic therapy has gained popularity as a less invasive option. The presence of esophageal dysmotility complicates the choice of surgical fundoplication. Most literature demonstrates that fundoplication is safe in the setting of ineffective or weak peristalsis and that postoperative dysphagia cannot be predicted by preoperative manometry parameters. More data are needed on the merits of endoluminal approaches to GERD.

Abstract
The autonomic dysfunction in palmar hyperhidrosis (PH) includes not only sympathetic overactivity but also parasympathetic impairment. A decrease of parasympathetic tone has been noted in gastroesophageal reflux disease of neonates and adults. Patients with reflux esophagitis have a defective anti-reflux barrier. The association between reflux esophagitis and PH is deliberated in this article. The National Health Insurance Database in Taiwan was used. At first-time visits, PH patients were identified by the International Classification of Disease, 9th Revision, Clinical Modification disease code of 780.8 without endoscopic thoracic sympathectomy. Patients were matched by age and gender as control groups. The reflux esophagitis incidence was assessed using disease codes 530.11, 530.81, and 530.85. The factors related to reflux esophagitis were established by the Cox proportional regression model. The risk of reflux esophagitis in PH patients had a hazard ratio of 3.457 (95% confidence interval: 3.043-3.928) after adjustment of the other factors. We confirmed the association between reflux esophagitis and PH. Health care providers must be alerted to this relationship and other risk factors of reflux esophagitis to support suitable treatments to improve the quality of life of patients.

Abstract
Importance Restoration of the esophagogastric junction competence is critical for effective long-term treatment of gastroesophageal reflux disease. Surgical repair results in such restoration, but mechanical adverse effects seem unavoidable. Minimizing these adverse effects without jeopardizing reflux control is warranted. Objective To determine whether partial fundoplication (PF) or total fundoplication (TF) is superior in laparoscopic antireflux surgery. Design, Setting, and Participants In this double-blind, randomized clinical trial of 1171 patients scheduled for laparoscopic antireflux surgery at a single university-affiliated center between November 19, 2001, and January 24, 2006, 456 patients were randomized and followed up for 5 years. Data were collected from November 2001 to April 2012, and data were analyzed from April 2012 to September 2018. Interventions A 270° posterior PF or a 360° Nissen TF. Main Outcomes and Measures Esophageal acid exposure at 3 years after surgery. Result Of the 456 randomized patients, 268 (58.8%) were male, and the mean (SD) age was 49.0 (11.7) years. A total of 229 patients were randomized to PF, and 227 patients were randomized to TF. At 3 years postoperatively, the median (interquartile range) esophageal acid exposure was reduced from 14.6% (9.8-21.9) to 1.8% (0.7-4.4) after PF and from 16.0% (10.4-22.7) to 2.5% (0.8-6.8) after TF (P = .31). Likewise, reflux symptoms were equally and effectively controlled. Early postoperative dysphagia (6 weeks) was common in both groups but then decreased toward normality. A small but statistically significant difference in favor of PF was noted in the mean (SD) scoring of dysphagia for liquids at 6 weeks (PF, 1.6 [0.9]; TF, 1.9 [1.3]; P = .01) and for solid food at 12 months (PF, 1.3 [1.0]; TF, 1.9 [1.4]; P < .001) and 24 months (PF, 1.3 [0.9]; TF, 1.7 [1.2]; P = .001). Quality of life was reduced before surgery but increased to normal values after surgery and remained so over 5-year follow-up, with no difference between the groups. Conclusions and Relevance The results from this randomized clinical trial suggest that although PF and TF could be recommended for treatment of gastroesophageal reflux disease, PF might be superior by inducing less dysphagia. Trial Registration ClinicalTrials.gov identifier: NCT03659487.

Abstract
Gastroesophageal reflux disease is a chronic condition with a high prevalence in western countries. Transient lower esophageal sphincter relaxation episodes and a decreased lower esophageal sphincter pressure are the main mechanisms involved. Currently used drugs are efficient on reflux symptoms, but only as long as they are administered, because they do not modify the reflux barrier. Certain nutrients or foods are generally considered to increase the frequency of gastroesophageal reflux symptoms, therefore physicians recommend changes in diet and some patients avoid bothering foods. This review summarizes current knowledge regarding food and gastroesophageal reflux. For example, fat intake increases the perception of reflux symptoms. Regular coffee and chocolate induce gastroesophageal reflux and increase the lower esophageal exposure to acid. Spicy foods might induce heartburn, but the exact mechanism is not known. Beer and wine induce gastroesophageal reflux, mainly in the first hour after intake. For other foods, like fried food or carbonated beverages data on gastroesophageal reflux is scarce. Similarly, there are few data about the type of diet and gastroesophageal reflux. Mediterranean diet and a very low carbohydrate diet protect against reflux. Regarding diet-related practices, consistent data showed that a "short-meal-to-sleep interval" favors reflux episodes, therefore some authors recommend that dinner should be at least four hours before bedtime. All these recommendations should consider patient's weight, because several meta-analyses showed a positive association between increased body mass index and gastroesophageal reflux disease.

Abstract
Gastroesophageal reflux disease (GERD) is quite prevalent worldwide, especially in the western hemisphere. The pathophysiology of GERD is complex, involving an incompetent esophagogastric junction (EGJ) as an anti-reflux barrier, as well as other co-morbid conditions such as gastroparesis, hiatal herniation or hyper acid secretion. Esophageal dysmotility is also frequently encountered in GERD, further contributing to the disease in the form of fragmented peristalsis, ineffective esophageal motility (IEM) or the more severe aperistalsis. The latter is quite common in systemic connective tissue disorders such as scleroderma. The main stay treatment of GERD is pharmacologic with proton pump inhibitors (PPI), with surgical fundoplication offered to patients who are not responsive to medications or would like to discontinue them for medical or other reasons. The presence of esophageal dysmotility that can worsen or create dysphagia can potentially influence the choice of fundoplication (partial or complete), or whether it is even possible. Most of the existing literature demonstrates that fundoplication may be safe in the setting of ineffective or weak peristalsis, and that post-operative dysphagia cannot be reliably predicted by pre-operative manometry parameters. In cases of complete aperistalsis (scleroderma-like esophagus), partial fundoplication can be offered in select patients who exhibit prominent reflux symptoms after a comprehensive multidisciplinary evaluation. Roux-en-Y gastric bypass is an alternative to fundoplication in patients with this extreme form of esophageal dysmotility, after careful consideration of the nutritional status.

Matrix association region/scaffold attachment region: the crucial player in defining the positions of chromosome breaks mediated by bile acid-induced apoptosis in nasopharyngeal epithelial cells.

Abstract
Background It has been found that chronic rhinosinusitis (CRS) increases the risk of developing nasopharyngeal carcinoma (NPC). CRS can be caused by gastro-oesophageal reflux (GOR) that may reach nasopharynx. The major component of refluxate, bile acid (BA) has been found to be carcinogenic and genotoxic. BA-induced apoptosis has been associated with various cancers. We have previously demonstrated that BA induced apoptosis and gene cleavages in nasopharyngeal epithelial cells. Chromosomal cleavage occurs at the early stage of both apoptosis and chromosome rearrangement. It was suggested that chromosome breaks tend to cluster in the region containing matrix association region/scaffold attachment region (MAR/SAR). This study hypothesised that BA may cause chromosome breaks at MAR/SAR leading to chromosome aberrations in NPC. This study targeted the AF9 gene located at 9p22 because 9p22 is a deletion hotspot in NPC. Methods Potential MAR/SAR sites were predicted in the AF9 gene by using MAR/SAR prediction tools. Normal nasopharyngeal epithelial cells (NP69) and NPC cells (TWO4) were treated with BA at neutral and acidic pH. Inverse-PCR (IPCR) was used to identify chromosome breaks in SAR region (contains MAR/SAR) and non-SAR region (does not contain MAR/SAR). To map the chromosomal breakpoints within the AF9 SAR and non-SAR regions, DNA sequencing was performed. Results In the AF9 SAR region, the gene cleavage frequencies of BA-treated NP69 and TWO4 cells were significantly higher than those of untreated control. As for the AF9 non-SAR region, no significant difference in cleavage frequency was detected between untreated and BA-treated cells. A few breakpoints detected in the SAR region were mapped within the AF9 region that was previously reported to translocate with the mixed lineage leukaemia (MLL) gene in an acute lymphoblastic leukaemia (ALL) patient. Conclusions Our findings suggest that MAR/SAR may be involved in defining the positions of chromosomal breakages induced by BA. Our report here, for the first time, unravelled the relation of these BA-induced chromosomal breakages to the AF9 chromatin structure.

Abstract
BACKGROUND The initial approach to gastroesophageal reflux disease (GERD) management typically involves lifestyle modification and medical therapy utilizing acid reducing agents such as histamine blockers and proton pump inhibitors. In severe cases refractory to such treatments, surgical therapy may be indicated. The gold standard for surgical treatment of GERD is the laparoscopic Nissen fundoplication. In recent years, a new technique known as magnetic sphincter augmentation (MSA) has been developed using the Linx™ Reflux Management System. This is an implantable ring of magnetic beads that is placed around the esophagus at the gastroesophageal junction to restore lower esophageal integrity. The aim of this review is to discuss the current literature regarding indications, surgical technique, efficacy, and complications of MSA using the Linx device. METHODS A standardized literature search was performed yielding 367 abstracts. After elimination due to duplicates between databases and irrelevance, 96 articles remained. The information found to be significant and non-redundant was included in this review. CONCLUSION After several years of clinical application, the Linx device has been shown to not only be effective for the management of GERD but also be as effective as fundoplication. With respect to safety, the most common complication of MSA is dysphagia. This often resolved without intervention, but esophageal dilation or device explanation are occasionally necessary. Not fully appreciated in earlier reviews, erosion of the device into the esophagus appears to be the most significant complication of the device after extended follow-up. While very rare, the potentially severe consequences of this phenomenon suggest that the device should be used with some restraint and that patients should be made aware of this potential morbidity. Fortunately, in the few cases of device erosion described in the literature reviewed, the Linx device was easily and safely removed.

Abstract
Background Esophageal shortening (ES) might be observed during high-resolution manometry (HRM), in particular after the rapid drink test (RDT). We aimed to assess its diagnostic value in patients referred for HRM. Methods HRM of patients without previous esophagogastric surgery or endoscopic treatment was retrospectively reviewed using the Chicago Classification v3.0. ES and pan-esophageal pressurization were analyzed during the RDT (200-ml free drinking in a sitting position). Results A total of 2141 cases (1291 females, mean age 54 years) were reviewed. During the RDT, ES occurred in 4% and pan-esophageal pressurization in 14% of patients. ES was almost exclusively encountered in patients with impaired esophagogastric junction relaxation or major disorders of peristalsis. Among 31 patients with ES and no definite diagnosis of achalasia, 19 had follow-up and 13 (68%) changed diagnostic category: two adenocarcinoma of the cardia, and 11 cases of atypical achalasia. The positive predictive value of ES for a significant esophageal disorder was 95%. Conclusion ES is rarely observed during the RDT. When present, it is associated with major motility disorders, especially achalasia. When the diagnostic criteria for achalasia are not fulfilled, further complementary examinations should be performed to rule out incomplete forms of achalasia or an infiltrative process of the cardia.

Abstract
PURPOSE Abdominal ultrasound (US) can visualize the esophagogastric junction (EGJ) as a hyperechoic area in the dorsal portion of the lateral segment of the liver. We prospectively evaluated the EGJ using US elastography (US-EG) in patients with reflux esophagitis (RE) to examine prediction of distal esophageal function. METHODS Of 108 patients undergoing US-EG and esophagogastroduodenoscopy, 102 in whom the EGJ was observed for ≥ 15 s were included. The subjects were divided into a RE group (n = 41, Grade M/A/B:24/13/4 according to modified Los Angeles Classification) and a non-RE group (n = 61). Direct strain elastography (LOGIQ E9, GE Healthcare), which gives a semi-quantitative elasticity index within a region of interest including the lateral segment, was used as a standard for measurement of the change in stiffness (CS) at the EGJ. RESULTS The number of CS as determined by US-EG was 6.0 (5.5-6.7) in the RE group and 8.6 (6.6-10.0) in the non-RE group (P < 0.0001). In ROC analysis, the AUC was 0.8415 for diagnosis of RE using the number of CS. At a cut-off of 7.7, the sensitivity, specificity, and accuracy for diagnosis were 92.7, 65.6, and 74.5%, respectively. CONCLUSION The presence of RE can be predicted based on US-EG.

Medications that relax the lower oesophageal sphincter and risk of oesophageal cancer: An analysis of two independent population-based databases. Int J Cancer 2018; 143:22-31.

Abstract
Excessive lower oesophageal sphincter relaxation increases gastro-oesophageal acid reflux, an oesophageal adenocarcinoma risk factor. Medications that relax this sphincter (benzodiazepines, calcium channel blockers, nitrates, β2 agonists and xanthines) could promote cancer. These medications were investigated in two independent datasets. In the Scottish Primary Care Clinical Informatics Unit (PCCIU) database, a nested case-control study of oesophageal cancer was performed using GP prescription records. Conditional logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (CIs) for medication use and oesophageal cancer. In UK Biobank, a cohort study was conducted using self-reported medication use. Cox regression was used to calculate hazard ratios (HRs) and 95% CIs for medication use and oesophageal cancer, and by tumour subtype. Overall, 1,979 oesophageal cancer patients were matched to 9,543 controls in PCCIU, and 355 of 475,768 participants developed oesophageal cancer in UK Biobank. None of the medications investigated were significantly associated with oesophageal cancer risk apart from β2 agonists, which were associated with increased oesophageal cancer risk in PCCIU (adjusted OR 1.38, 95% CI 1.12, 1.70) but not in UK Biobank (adjusted HR 1.21, 95% CI 0.70, 2.08). Medications that relax the lower oesophageal sphincter were not associated with oesophageal cancer, apart from β2 agonists. This increased cancer risk in β2 agonist users merits further investigation.

Abstract
BACKGROUND Esomeprazole is commonly administered with food; however, clinical data to support this practice are lacking. We aimed to determine the effect of postprandial ingestion of esomeprazole on reflux symptoms among patients with gastroesophageal reflux disease (GERD). METHODS Consecutive patients with GERD adequately controlled with esomeprazole 40 mg daily, entered a 2-week lead-in period during which esomeprazole was administered 30 min before breakfast. Patients were then randomized to continue preprandial ingestion or to ingest esomeprazole following a standardized meal. Outcomes included GERD frequency and severity indices, GERD-health-related quality of life (GERD-HRQL) questionnaire and Short Form 36 (SF-36). RESULTS Thirty-two patients (17 [53.1%] men, aged 53.5 ± 17.2 years) were included, and 16 (50%) switched to postprandial ingestion of esomeprazole. GERD frequency and severity decreased in both groups (Δ9.0 ± 7.2 vs. Δ10.0 ± 8.1, p = 0.29; Δ6.6 ± 6.8 vs. Δ10.2 ± 7.4, p = 0.57 in postprandial group vs. controls, for frequency and severity, respectively). GERD-HRQL improved in both study groups to a similar degree (Δ10.7 ± 10.5 vs. Δ10.0 ± 13.8, p = 0.97). All SF-36 subscores increased in both groups to a similar degree. In a mixed linear model, there were no differences between the study groups in the changes observed in GERD frequency (p = 0.49), severity (p = 0.32), and GERD-HRQL (p = 0.98) during the study period. CONCLUSION Switching to postprandial administration of esomeprazole is not associated with deterioration in reflux symptoms among patients with GERD. Esomeprazole seems to remain efficacious when administered after meals.

J Neurogastroenterol Motil 2018; 24:241-247. [PMID: 29605979 PMCID: PMC5885723 DOI: 10.5056/jnm16111] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2016] [Revised: 07/26/2017] [Accepted: 10/13/2017] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND/AIMS The novel prokinetic drug acotiamide is used for treatment of functional dyspepsia. It is still unclear how acotiamide has effects on esophageal motor function. Esophageal peristalsis and esophagogastric junction (EGJ) compliance has an important role for prevention of esophageal mucosal damage caused by gastroesophageal reflux, however, few studies have analyzed the effects of acotiamide on those former activities and none have investigated its effects on EGJ compliance. The aim of our research was to examine the effects of acotiamide on esophageal motility and EGJ compliance. METHODS We enrolled 3 gastroesophageal reflux disease (GERD) patients as well as 9 healthy volunteers. Using high-resolution manometry, we examined esophageal motor activity parameters, including esophageal body contractions and lower esophageal sphincter (LES) pressure. While, EGJ compliance was evaluated using a functional lumen imaging probe. Following determination of baseline values for esophageal motor activities and EGJ compliance, acotiamide at a standard dose of 300 mg/day was administered for 3 days. All measurements were performed again 2 hours after the last acotiamide administration. RESULTS In the healthy volunteers, as compared with the baseline values, acotiamide administration did not significantly change esophageal body contractions and LES pressure. And EGJ distensibility was not significantly changed (distensibility index in 40-mL distension: 3.5 ± 0.4 vs 3.3 ± 0.5 mm²/mmHg). Similarly in the GERD patients, there were no differences in either esophageal motility or EGJ compliance between before and after acotiamide administration (distensibility index in 40-mL distension: 6.2 ± 0.5 vs 6.5 ± 1.1 mm²/mmHg). CONCLUSION In both healthy individuals and GERD patients, standard dose acotiamide dose does not have significant effects on esophageal motor activities or EGJ compliance.
