Abstract
High-resolution manometry (HRM) is a diagnostic tool for surgeons, gastroenterologists and other healthcare professionals to evaluate esophageal physiology. The Chicago Classification (CC) system is based on a consensus of worldwide experts to minimize ambiguity in HRM data acquisition and diagnosis of esophageal motility disorders. The most updated version, CCv4.0, was published in 2021; however, it does not provide step-by-step guidelines (i.e., for beginners) on how to assess the most important HRM metrics. This paper aims to summarize the basic guidelines for conducting a high-quality HRM study including data acquisition and interpretation, based on CCv4.0, using Manoview ESO analysis software, version 3.3 (Medtronic, Minneapolis, MN).

Abstract
INTRODUCTION Having performed anti-reflux surgery for thirty years, it was important to reexamine our patients in the long term to enlarge the body of evidence concerning classical and extraesophageal symptoms that are differently controlled by Nissen or Toupet fundoplication. OBJECTIVES We report a cohort of 155 GERD patients who underwent fundoplication within a tailored approach between 1994 and 2000. Changes in the perioperative functional outcome, GERD symptoms, and quality of life are being analyzed 10 and 20 years after the operation. RESULTS The operation resulted in a superior quality of life compared to a patient cohort treated with PPI therapy. We found that both surgical methods (laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication) cure classical symptoms equally (heartburn, regurgitation, and dysphagia). GERD patients receiving a Toupet fundoplication seem more likely to suffer from extraesophageal GERD symptoms 10 and 20 years after surgery than patients with a Nissen fundoplication. On the other hand, some patients with Nissen fundoplication report dysphagia even 10 and 20 years after surgery. CONCLUSION Both the laparoscopic Nissen and Toupet fundoplications provide excellent symptom control in the long term. Moreover, the Nissen fundoplication seems to be superior in controlling extraesophageal reflux symptoms, but at the expense of dysphagia. In summary, tailoring the operation based on symptoms seems advantageous.

Abstract
The common denominator for virtually all episodes of gastroesophageal reflux in health and disease is the loss of the barrier that confines the distal esophagus to the stomach. Factors important in maintaining the function of the barrier are its pressure, length and position. In early reflux disease, overeating, gastric distention and delayed gastric emptying led to a transient loss of the barrier. A permanent loss of the barrier occurs from inflammatory injury to the muscle allowing free flow of gastric juice into the esophageal body. Corrective therapy requires augmentation or restoration of the barrier referred to more commonly as the lower esophageal sphincter.

Abstract
OBJECTIVE To evaluate the impact of MSA on lower esophageal sphincter (LES) and esophageal body using high resolution impedance manometry. BACKGROUND MSA is an effective treatment in patients with gastroesophageal reflux disease, but there is limited data on its impact on esophageal functional physiology. METHODS Patients who underwent MSA were approached 1-year after surgery for objective foregut testing consists of upper endoscopy, esophagram, high resolution impedance manometry, and esophageal pH-monitoring. Postoperative data were then compared to the preoperative measurements. RESULTS A total of 100 patients were included in this study. At a mean follow up of 14.9(10.1) months, 72% had normalization of esophageal acid exposure. MSA resulted in an increase in mean LES resting pressure [29.3(12.9) vs 25(12.3), P < 0.001]. This was also true for LES overall length [2.9(0.6) vs 2.6(0.6), P = 0.02] and intra-abdominal length [1.2(0.7) vs 0.8(0.8), P < 0.001]. Outflow resistance at the EGJ increased after MSA as demonstrated by elevation in intrabolus pressure (19.6 vs 13.5 mmHg, P < 0.001) and integrated relaxation pressure (13.5 vs 7.2, P < 0.001). MSA was also associated with an increase in distal esophageal body contraction amplitude [103.8(45.4) vs 94.1(39.1), P = 0.015] and distal contractile integral [2647.1(2064.4) vs 2099.7(1656.1), P < 0.001]. The percent peristalsis and incomplete bolus clearance remained unchanged ( P = 0.47 and 0.08, respectively). CONCLUSIONS MSA results in improvement in the LES manometric characteristics. Although the device results in an increased outflow resistance at the EGJ, the compensatory increase in the force of esophageal contraction will result in unaltered esophageal peristaltic progression and bolus clearance.

Abstract
Background Pathophysiology of gastroesophageal reflux disease (GERD) shows a multifactorial background. Different anatomical and functional alterations can be determined such as weakness of the lower esophageal sphincter (LES), changes in anatomy by a hiatal hernia (HH), an impaired esophageal motility (IEM), and/or an associated gastric motility problem with either duodeno-gastro-esophageal reflux (DGER) or delayed gastric emptying (DGE). The purpose of this study is to assess a large GERD-patient population to quantitatively determine different pathophysiologic factors contributing to the disease. Methods For this analysis only patients with documented GERD (pathologic esophageal acid exposure) were selected from a prospectively maintained databank. Investigations: history and physical, body mass index, endoscopy, esophageal manometry, 24 h-pH-monitoring, 24 h-bilirbine-monitoring, radiographic-gastric-emptying or scintigraphy, gastrointestinal quality of life index (GIQLI). Results In total, 728 patients (420 males; 308 females) were selected for this analysis. Mean age: 49.9 years; mean BMI: 27.2 kg/m2 (range, 20-45 kg/m2); mean GIQLI of 91 (range: 43-138; normal level: 121); no esophagitis: 30.6%; minor esophagitis (Savary-Miller type 1 or Los Angeles Grade A): 22.4%; esophagitis [2-4]/B-D: 36.2%; Barrett's esophagus 10%. Presence of pathophysiologic factors: HH 95.4%; LES-incompetence 88%, DGER 55%, obesity 25.6%, IEM 8.8%, DGE 6.8%. Conclusions In our evaluation of GERD patients, the most important pathophysiologic components are anatomical alterations (HH), LES-incompetence and DGER.

Abstract
BACKGROUND Many factors may play a role in the severity and progression of gastroesophageal reflux disease (GERD) since pathophysiology is multifactorial. Data regarding the progression of GERD are controversial: some reports of increased esophageal acid exposure (EAE) and mucosal damage were considered as evidence for a stable disease course, while others interprete these findings as disease progression. The aim of this study is to analyze a large patient-population with persisting symptoms indicative of GERD under protonpumpinhibitor-therapy and identify components characterizing disease severity and progression. METHODS Patients with symptoms indicative of GERD were included in the study in a tertiary referral center (Frankfurt, Germany). All selected patients were under long-term protonpumpinhibitor-therapy with persistant symptoms. All patients underwent investigations to collect data on their physical status, EAE, severity of esophagitis, anatomical changes, and esophageal functional defects as well as their relation to the duration of the disease. Incidence over time was plotted as survival curves and tested with Log-rank tests for the four main disease markers. Multivariate modeling with COX-regression model was used to estimate the general impact of the four main disease markers on the time course of the disease. In order to elucidate possible causal relationships over time, a path analysis (structural equation model) was calculated. RESULTS From the database with 1480 data sets, 972 patients were evaluated (542 males, 430 females). The mean age was 50.5 years (range18-89). The mean body mass index was 27.2(19-48). The mean time between the onset of symptoms and the diagnostic investigations was 8.2 years (1-50). A longer disease history for GERD was significantly associated with a higher risk for LES-incompetence. The mean duration from symptom onset to the time of clinical investigation was 9 years for patients with LES-incompetence (n = 563), compared to a mean of 6 years for those with mechanically intact LES (n = 95). A longer period from symptom onset to diagnostics was significantly associated with higher acid exposure. The pathway analysis was significant for the following model: 'history' (P < 0.001➔LES-incompetence & Hiatal Hernia➔(p < 0,001)➔pH-score (P < 0.001).Conclusion: LES-incompetence, the functional deterioration of the LES, and the anatomical alteration at the esophagogastric junction (Hiatal Hernia) as well as an increased EAE were associated with a long history of suffering from GERD. Path modeling suggests a causal sequence overtime of the main disease-parameters, tentatively allowing for a prediction of the course of the disease.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most commonly encountered digestive diseases in the world, with the prevalence continuing to increase. Many patients are successfully treated with lifestyle modifications and proton pump inhibitor therapy, but a subset of patients require more aggressive intervention for control of their symptoms. Surgical treatment with fundoplication is a viable option for patients with GERD, as it attempts to improve the integrity of the lower esophageal sphincter (LES). While surgery can be as effective as medical treatment, it can also be associated with side effects such as dysphagia, bloating, and abdominal pain. Therefore, a thorough pre-operative assessment is crucial to select appropriate surgical candidates. Newer technologies are becoming increasingly available to help clinicians identify patients with true LES dysfunction, such as pH-impedance studies and high-resolution manometry (HRM). Pre-operative evaluation should be aimed at confirming the diagnosis of GERD, ruling out any major motility disorders, and selecting appropriate surgical candidates. HRM and pH testing are key tests to consider for patients with GERD like symptoms, and the addition of provocative measures such as straight leg raises and multiple rapid swallows to HRM protocol can assess the presence of underlying hiatal hernias and to test a patient’s peristaltic reserve prior to surgery.

Abstract
LSG is one of the most performed bariatric procedures worldwide. It is a safe and effective operation with a low complication rate. Unsatisfactory weight loss/regain may occur, suggesting that the operation design could be improved. A bioengineering approach might significantly help in avoiding the most common complications. Computational models of the sleeved stomach after LSG were developed according to bougie size (range 27-54 Fr). The endoluminal pressure and the basal volume were computed at different intragastric pressures. At an inner pressure of 22.5 mmHg, the basal volume of the 54 Fr configuration was approximately 6 times greater than that of the 27 Fr configuration (57.92 ml vs 9.70 ml). Moreover, the elongation distribution of the gastric wall was assessed to quantify the effect on mechanoreceptors impacting satiety by differencing regions and layers. An increasing trend in elongation strain with increasing bougie size was observed in all cases. The most stressed region and layer were the antrum (approximately 25% higher stress than that in the corpus at 37.5 mmHg) and mucosa layer (approximately 7% higher stress than that in the muscularis layer at 22.5 mmHg), respectively. In addition, the pressure-volume behaviors were reported. Computational models and bioengineering methods can help to quantitatively identify some critical aspects of the "design" of bariatric operations to plan interventions, and predict and increase the success rate. Moreover, computational tools can support the development of innovative bariatric procedures, potentially skipping invasive approaches.

Pathological Implications of Swallow-Associated Transient Lower Esophageal Sphincter Elevation. J Gastrointest Surg 2020; 24:2705-2713.

Abstract
BACKGROUND The lower esophageal sphincter (LES) overlaps the crural diaphragm (CD) in patients without hiatal hernia (HH). Swallowing induces esophageal peristalsis with longitudinal esophageal shortening, causing transient elevation of the LES above the CD. This phenomenon, visible on high-resolution manometry (HRM), is called swallow-induced transient HH (tHH). METHODS We assessed pathological implications of swallow-induced LES elevation. We included patients who underwent 24-h pH monitoring and HRM between January 1, 2017 and June 30, 2018. Patients with manometric HH were excluded. Patients were divided into 3 groups: persistent tHH, which indicated significant LES-CD separation (i.e., ≥ 1cm in ≥ 30% swallows, or ≥ 2cm in ≥ 10% swallows) at the second inspiration after the conclusion of swallow-induced esophageal peristalsis; incidental tHH, which indicated significant LES-CD separation at the first inspiration after peristalsis without meeting persistent tHH criterion; and non-tHH. RESULTS In total, 107 patients were included. There were 18 patients in the persistent tHH group, 54 in the incidental tHH group, and 35 in the non-tHH group. No differences were observed in esophageal body motility or LES antireflux barrier parameters among groups. However, patients with persistent tHH had significantly higher DeMeester scores, longer acid exposure time, and poorer acid clearance. Prevalence of pathological reflux was 83.3% in the persistent tHH cohort. Esophagogastroduodenoscopy showed that 76.9% of patients with persistent tHH had no HH. Endoscopic findings of the esophagogastric junction were similar among groups. CONCLUSIONS Persistent tHH seems to be a pathological finding associated with pathological reflux.

Abstract
BACKGROUND Noncardiac chest pain often coexists with dysphagia in patients diagnosed with achalasia. The current standard treatment for achalasia, laparoscopic Heller myotomy with Dor fundoplication, has an insufficient effect on noncardiac chest pain. The aim of this study is to investigate the efficacy of circumferential Heller myotomy on esophageal chest pain in patients with achalasia. METHODS Twenty patients diagnosed with achalasia who complained of noncardiac chest pain were recruited and underwent circumferential Heller myotomy. Using an institutional achalasia database, we randomly selected 60 patients who underwent standard laparoscopic Heller myotomy with Dor fundoplication, based on a 3-to-1 propensity score-matching analysis. We compared surgical outcomes between the circumferential Heller myotomy and the laparoscopic Heller myotomy with Dor fundoplication groups. RESULTS Patients undergoing circumferential Heller myotomy had a higher rate of postoperative noncardiac chest pain relief than the laparoscopic Heller myotomy with Dor fundoplication group [95% (19/20) vs. 75% (45/60), p = 0.045]. No differences in dysphagia and vomiting were found between groups (p = 0.783 and p = 0.645, respectively). Patients in the circumferential Heller myotomy group had significantly better esophageal clearance. The prevalence of reflux endoscopic esophagitis was higher in the circumferential Heller myotomy group than in the control group [35.0% (7/20) vs. 10.0% (6/60), p = 0.015]. CONCLUSIONS There is promising early evidence that circumferential Heller myotomy may be effective in the treatment of achalasia-related chest pain. Further research, including larger randomized studies with long-term follow-up, is warranted.

Abstract
Gastroesophageal reflux disease (GERD), a prevalent problem among obese individuals, is strongly associated with obesity and weight loss. Hence, bariatric surgery effectively improves GERD for many patients. Depending on the type of bariatric procedure, however, surgery can also worsen or even cause a new onset of GERD. As a consequence, GERD remains a relevant problem for many bariatric patients, and especially those who have undergone sleeve gastrectomy (SG). Affected patients report not only a decrease in physical functioning but also suffer from mental and emotional problems, resulting in poorer social functioning. The pathomechanism of GERD after SG is most likely multifactorial and triggered by the interaction of anatomical, physiological, and physical factors. Contributing factors include the shape of the sleeve, the extent of injury to the lower esophageal sphincter, and the presence of hiatal hernia. In order to successfully treat post-sleeve gastrectomy GERD, the cause of the problem must first be identified. Therapeutic approaches include lifestyle changes, medication, interventional treatment, and/or revisional surgery.

Abstract
BACKGROUND The esophagogastric junction (EGJ) is an anatomic and physiologic barrier against gastroesophageal reflux. Comprehensive evaluation of EGJ barrier parameters using high-resolution manometry in patients with GERD has not been well established. We propose a simple index for comprehensive EGJ antireflux competency. STUDY DESIGN Patients who underwent high-resolution manometry and 24-hour pH monitoring between January 2017 and September 2018 were included. Of these, patients with normal esophageal motility were selected. EGJ antireflux competency was assessed based on the following 3 categories: anatomic configuration of the EGJ complex (ie EGJ morphology), backflow-preventive pressure on the lower esophageal sphincter (LES) (ie LES pressure integral), and backflow-promotive pressure across the LES (ie thoracoabdominal pressure gradient). Each category was scored on a scale of 0 to 2, applying clinically meaningful divisions, and a cumulative score was calculated (EGJ index: 0 to 6 points). DeMeester score > 14.72 indicated GERD. RESULTS In total, 259 patients met study criteria. Of these, GERD was noted in 109 patients (42.1%). The pH parameters were gradually exacerbated, depending on the EGJ index. Good correlations were seen between EGJ index and previously proposed parameters for EGJ disruption, including LES length, LES pressure, and LES pressure integral (area under the curve > 0.9 [excellent validation]). No patient had GERD if the EGJ index score was 0. However, GERD was seen in as high as 85.7% of patients with the highest score of 6. CONCLUSIONS EGJ disruption severity was clearly graded based on a simple scoring method, which can improve evaluation and development of clinical strategies for GERD.

Abstract
Summary
Background
Present diagnosis and management of gastroesophageal reflux disease (GERD)
has resulted in a dramatic increase in the incidence of esophageal adenocarcinoma. This
is due to failure to identify pathologic changes of early GERD; at present, pathology is
limited to management of Barrett esophagus (BE).
Methods
Convincing evidence have confirmed that cardiac mucosa distal to the
squamocolumnar junction in the endoscopically normal person is a metaplastic GERD-induced esophageal epithelium, and not a normal proximal gastric epithelium.
Results
When cardiac mucosa is recognized as a metaplastic esophageal epithelium, it
becomes self-evident that the present endoscopic definition of the gastro-esophageal
junction is incorrect, and there exists a dilated distal esophagus (DDE) in what is
incorrectly termed the “gastric cardia” presently mistaken for proximal stomach. It also
becomes clear that the length of the DDE correlates with the presence and severity of
GERD and represents the pathology of the entire spectrum of GERD. Further, it allows
recognition that the DDE, measured as the gap between esophageal squamous epithelium
and gastric oxyntic mucosa that is composed of cardiac mucosa, represents the pathologic
anatomy of damage to the abdominal segment of the lower esophageal sphincter (LES).
Conclusion
The new understanding of the significance of cardiac mucosa provides a new and highly accurate histologic method of assessment of LES damage, the primary cause of
GERD. This opens a new door to complete histologic assessment of GERD from its etiologic standpoint and to new research that permit early diagnosis of GERD at its outset.
Ultimately, such early diagnosis has the potential to reverse the increasing trend of
esophageal adenocarcinoma.

A budget impact analysis of a magnetic sphincter augmentation device for the treatment of medication-refractory mechanical gastroesophageal reflux disease: a United States payer perspective.

Abstract
BACKGROUND Medication-refractory gastroesophageal reflux disease (GERD) is sometimes treated with laparoscopic Nissen fundoplication (LNF); however, this is a non-reversible procedure associated with important side effects and the need for repeat surgery. Removable magnetic sphincter augmentation (MSA) devices are an alternative, effective, and safe treatment option for such patients who have some lower esophageal sphincter function. The objective of this study was to assess the economic impact of introducing MSA technology (i.e., LINX Reflux Management System) into current practice from a US-payer perspective. METHODS An economic budget impact model was developed over a 1-year time horizon that compared current treatment of GERD patients who are medically managed (but refractory) or receiving LNF to future treatment of GERD patients that included a mix of patients treated with medical management only, LNF, or MSA. Resources included within the analyses were index procedures (inpatient and outpatient use), reoperations (revisions and removals), readmissions, healthcare visits, diagnostic tests, procedures, and medications. Medicare payment rates were typically used to inform unit costs. RESULTS Assuming a hypothetical commercial insurance population of 1 million members, the base-case analysis estimated a net cost savings of $111,367 with introduction of the MSA. This translates to a savings of $0.01 per member per month. Results were largely driven by avoided inpatient procedures with use of the MSA device. Alternative analyses exploring the potential impact of increasing surgical volumes predicted that results would remain cost saving if the proportion of MSA market share taken from LNF was ≥ 90%. CONCLUSIONS This study predicts that the introduction of the MSA device would lead to favorable budget impact results for the treatment of medication-refractory mechanical GERD for commercial payers. Future analyses will benefit from inclusion of middle-ground treatments as well as longer time horizons.

Abstract
Gastroesophageal reflux disease (GERD) clinical presentation may encompass a myriad of symptoms that may mimic other esophageal and extra-esophageal diseases. Thus, GERD diagnosis by symptoms only may be inaccurate. Upper digestive endoscopy and barium esophagram may also be misleading. pH monitoring must be added often for a definitive diagnosis. The DeMeester score (DMS) is a composite score of the acid exposure during a prolonged ambulatory pH monitoring that has been used since 1970s to categorize patients as GERD+ or GERD-. We showed in this review that DMS has some limitations and strengths. Although there is not a single instrument to precisely diagnose GERD in all of its variances, pH monitoring analyzed at the light of DMS is still a reliable method for scientific purposes as well as for clinical decision making. There are no data that show that acid exposure time is superior-or for that matter inferior-as compared to DMS.

Abstract
BACKGROUND Attention has been focused on the amplitude of esophageal body contraction to avoid persistent dysphagia after a Nissen fundoplication. The current recommended level is a contraction amplitude in the distal third of esophagus above the fifth percentile. We hypothesized that a more physiologic approach is to measure outflow resistance imposed by a fundoplication, which needs to be overcome by the esophageal contraction amplitude. STUDY DESIGN The esophageal outflow resistance, as reflected by the intra-bolus pressure (iBP) measured 5 cm above the lower esophageal sphincter (LES), was measured in 53 normal subjects and 37 reflux patients with normal esophageal contraction amplitude, before and after a standardized Nissen fundoplication. All were free of postoperative dysphagia. A test population of 100 patients who had a Nissen fundoplication was used to validate the threshold of outflow resistance to avoid persistent postoperative dysphagia. RESULTS The mean (SD) amplitude of the iBP in normal subjects was 6.8 (3.7) mmHg and in patients before fundoplication was 3.6 (7.0) mmHg (p = 0.003). After Nissen fundoplication, the mean (SD) amplitude of the iBP increased to 12.0 (3.2) mmHg (p < 0.0001 vs normal subjects or preoperative values). The 95th percentile value for iBP after a Nissen fundoplication was 20.0 mmHg and was exceeded by esophageal contraction in all patients in the validation population, and 97% of these patients were free of persistent postoperative dysphagia at a median 50-month follow-up. CONCLUSIONS Nissen fundoplication increases the outflow resistance of the esophagus and should be constructed to avoid an iBP > 20 mmHg. Patients whose distal third esophageal contraction amplitude is >20 mmHg have a minimal risk of dysphagia after a tension-free Nissen fundoplication.

Abstract
In patients with Barrett's esophagus (BE), anti-reflux surgery aims to sustainable control reflux symptoms and heal reflux induced esophageal mucosal inflammation and prevent progression of BE to adenocarcinoma. There is growing evidence that beside gastric acid, bile salts in refluxed duodenal juice are responsible for the development and progression of BE. However, the pathogenesis of BE progression and the metaplasia-dysplasia-carcinoma sequence of the adenocarcinoma of the esophagus (EAC) is multifactorial and occurs over long natural time course. After anti-reflux surgery significant levels of regression from metaplastic Barrett's to non-metaplastic epithelium as well as from dysplastic to non-dysplastic BE have been observed and a randomized trial showed that sufficient surgical reflux control reduces the risk of Barrett's progression significantly when compared to medical treatment. Thus, large cohort studies show significant reduced risk of EAC in patients suffering from gastroesophageal reflux disease (GERD) with and without BE after anti-reflux surgery. Even after anti-reflux surgery the risk for EAC remains elevated in patients with BE and the right moment of intercepting the progressive nature of GERD has to be discussed in future. The paper also addresses the impact of anti-reflux surgery, endoscopic ablation and life style therapies for the management of GERD, BE and cancer prevention.

Abstract
Advanced lung disease is associated with gastroesophageal reflux disease (GERD). The thoracoabdominal pressure gradient (TAPG) facilitates gastroesophageal reflux, but the effects of TAPG on gastroesophageal reflux in patients with pulmonary disease have not been well defined. Patients diagnosed with end-stage lung disease are expected to have the most extreme derangement in respiratory mechanics. The aim of this study is to explore the relationship between TAPG and reflux in lung transplant (LTx) candidates. We reviewed LTx recipients who underwent pretransplant esophageal high-resolution manometry and a 24-hour pH study. Patients were excluded if they were undergoing redo LTx, had manometric hiatal hernia, or had previously undergone foregut surgery. TAPG was defined as the intra-abdominal pressure minus the intrathoracic pressure during inspiration. Adjusted TAPG was calculated by the TAPG minus the resting lower esophageal sphincter (LES) pressure (LESP). Twenty-two patients with normal esophageal function tests (i.e., normal esophageal motility with neither manometric hiatal hernia nor pathological reflux on 24-hour pH monitoring) were selected as the pulmonary disease-free control group. In total, 204 patients underwent LTx between January 2015 and December 2016. Of these, 77 patients met inclusion criteria. We compared patients with obstructive lung disease (OLD, n = 33; 42.9%) and those with restrictive lung disease (RLD, n = 42; 54.5%). 2/77 patients (2.6%) had pulmonary arterial hypertension. GERD was more common in the RLD group than in the OLD group (24.2% vs. 47.6%, P = 0.038). TAPG was similar between the OLD group and the controls (14.2 vs. 15.3 mmHg, P = 0.850); however, patients in the RLD group had significantly higher TAPG than the controls (24.4 vs. 15.3 mmHg, P = 0.002). Although TAPG was not correlated with GERD, the adjusted TAPG correlated with reflux in all 77 patients with end-stage lung disease (DeMeester score, rs = 0.256, P = 0.024; total reflux time, rs = 0.259, P = 0.023; total number of reflux episodes, rs = 0.268, P = 0.018). Additionally, pathological reflux was seen in 59.1% of lung transplant candidates with adjusted TAPG greater than 0 mmHg (i.e., TAPG exceeding LESP); GERD was seen in 30.9% of patients who had an adjusted TAPG ≤ 0 mmHg. In summary, TAPG varies based on the underlying cause of lung disease. Higher adjusted TAPG increases pathological reflux, even if patients have normal antireflux anatomy and physiology (i.e., no hiatal hernia and manometrically normal LES function). Adjusted TAPG may provide further insights into the pathophysiology of GERD.

Abstract
Manometry and 24-h pH interpretation have seldom been studied. Our aim was to study these parameters as gold standard in reflux disease and to identify predictors of pathological acid reflux. Retrospective case record review of all patients with reflux disease evaluated using endoscopy, manometry, and 24-h pH testing from 2010 to 2016. Patients were categorized using Johnson-DeMeester score into two groups-group I (score > 14.7, normal study) and group II (< 14.7, normal study). These groups were compared for the above-mentioned parameters. Appropriate statistical tests were applied. P-value < 0.05 was considered significant. The study group includes 94 patients (median age 44 years, 63.8% males). Sixty (63.8%) and 34 patients belonged to groups I and II, respectively, 76.6% patients had normal endoscopy while the remaining had mild esophagitis. Peristalsis was normal in 66%, followed by ineffective esophageal motility (19.1%) and fragmented peristalsis (14.9%). Demography, symptoms, endoscopy findings, and peristalsis characteristics were similar between the two groups. Group II patients had significantly lower basal lower esophageal sphincter (LES) pressure (11.9 vs. 16.6; p < 0.02), lower integrated relaxation pressure (5.7 vs. 7.4; p < 0.01), and larger separation between LES and crural diaphragm (1.7 vs. 1.4 cm; p < 0.003). Basal LES pressure < 10 mmHg had the highest likelihood ratio (2.2) to predict an abnormal pH study. Basal LES pressure, integrated relaxation pressure, and hiatus size correlated with pathological acid reflux. Hypotensive basal lower esophageal sphincter pressure was the best predictor of an abnormal pH study but with negative linear correlation.

Abstract
PURPOSE OF REVIEW To provide new concepts regarding the early pathologic changes of gastroesophageal reflux disease (GERD) that are associated with damage to the lower esophageal sphincter (LES). RECENT FINDINGS A body of evidence exists that cardiac mucosa is a metaplastic esophageal epithelium rather than a normal gastric epithelium. Recent studies in asymptomatic volunteers suggest a potential mechanism for cardiac metaplasia in the squamous epithelium of the esophagus. SUMMARY The concept that cardiac mucosa is esophageal, not gastric, suggests that the widely accepted endoscopic definition of the gastroesophageal junction (GEJ) is incorrect. I propose that the true GEJ is the proximal extent of gastric oxyntic epithelium. If there is cardiac mucosa lining proximal rugal folds, that cardiac mucosa-lined region is the dilated distal esophagus, not the proximal stomach. The dilated distal esophagus is the pathologic expression of damage to the abdominal segment of the LES. This concept suggests a new test for measuring damage to the abdominal LES and a new understanding of the disease of GERD based on the measured amount of LES damage. This opens the door to new research and change in objectives in the management of reflux disease from control of symptoms to prevention of complications such as Barrett's esophagus and adenocarcinoma.

Abstract
Longitudinal esophageal body shortening with swallow-induced peristalsis has been reported in healthy individuals. Esophageal shortening is immediately followed by esophageal re-elongation, and the lower esophageal sphincter (LES) returns to the baseline position. High-resolution manometry (HRM) allows for objective assessment of extent of shortening and duration of shortening. In patients without hiatal hernia at rest, swallow-induced esophageal shortening can lead to transient hiatal hernia (tHH) which at times may persist after the completion of swallow. This manometric finding has not been investigated in the literature, but a question arises whether this swallow-induced transient herniation can effect on the likelihood of gastroesophageal reflux. This study aims to assess the relationship between gastroesophageal reflux and the subtypes of swallow-induced esophageal shortening, i.e. tHH and non-tHH, in patients without hiatal hernia at rest. After Institutional Review Board (IRB) approval, we queried a prospectively maintained database to identify patients who underwent HRM evaluation and 24-hour pH study between January to December 2015. Patients with type-I esophagogastric junction (EGJ) morphology (i.e. no hiatal hernia) according to the Chicago classification v3.0 were included. The patterns of the esophageal shortening with swallows were divided into two subtypes, i.e. tHH and non-tHH. tHH was defined as an EGJ double high-pressure zones (≥1 cm) at the second inspiration after the termination of swallow-induced esophageal body contraction. The number of episodes of tHH was counted per 10 swallows and tHH size was measured for each patient. In total, 41 patients with EGJ morphology Type-I met the inclusion criteria. The mean age was 47.2 years, 35 patients (85.4%) were women, and the mean body mass index was 33.9 kg/m2. The mean number of tHH episodes was 3 out of 10 swallows; mean maximal tHH size was 1.3 cm. Patients who had tHH in ≥3 out of 10 swallows (n = 16; 39.0%) were more likely to have abnormal DeMeester scores than patients with <3 swallows (56% vs. 28%; P = 0.070). Patients with maximal tHH ≥2 cm in at least 1 swallow (n = 17; 41.5%) were more likely to experience pathological reflux than patients with maximal tHH <2 cm (59% vs. 25%; P = 0.029). In conclusion, we showed that, in a subset of patients with Type-I EGJ morphology, swallowing induced transient EGJ double high-pressure zones (≥1 cm) after peristalsis. We have named this new manometric finding the swallow-induced tHH. A high prevalence of pathological reflux disease was observed in patients with maximal tHH ≥2 cm. The degree of swallow-induced tHH could be an early indicator of lower esophageal sphincter dysfunction in patients without manometric hiatal hernia.

Abstract
Gastroesophageal reflux disease pathophysiology is multifactorial and linked to a misbalance between the aggressiveness of the refluxate into the esophagus or adjacent organs and the failure of protective mechanisms associate or not to a defective valvular mechanism at the level of the esophagogastric junction incapable of dealing with a transdiaphragmatic pressure gradient. Antireflux mechanisms include the lower esophageal sphincter and abdominal esophagus, the diaphragm, the angle of His, the Gubaroff valve, and the phrenoesophageal membrane. Protective mechanisms include esophageal motility, saliva production, and epithelial protection. Disruption of this balance occurs most commonly due to the presence of a hiatal hernia, esophageal dysmotility, a rise in abdominal pressure (obesity), and decrease in thoracic pressure (chronic lung diseases).

Abstract
BACKGROUND We have previously reported short-term outcomes after hiatal hernia repair (HHR) at the time of magnetic sphincter augmentation (MSA) for gastroesophageal reflux disease (GERD). Here we report intermediate-term outcomes and hernia recurrence rate after concomitant MSA and HHR. METHODS This is a retrospective cohort study of patients who underwent repair of a hiatal hernia 3 cm or larger at the time of MSA implantation between May 2009 and December 2015. The primary endpoint was hiatal hernia recurrence identified by routine postoperative videoesophagography or endoscopy. Recurrence was defined by a 2 cm or greater upward displacement of the stomach through the diaphragmatic esophageal hiatus. Secondary endpoints included cessation of proton-pump inhibitor (PPI), persistent dysphagia requiring intervention, and GERD health-related quality-of-life (HRQL) scores 1 year from surgery. RESULTS During the study period, 47 of 53 (89%) patients underwent concomitant MSA with HHR and complied with surveillance. Hiatal hernias ranged from 3 to 7 cm (mean 4 ± 1). Mean clinical follow-up time was 19 months (range 1-39). GERD-HRQL score decreased from 20.3 to 3.1 (p < .001), 89% of patients remained off PPIs, and 97% of patients reported improvement or resolution of symptoms. Two recurrent hiatal hernias were identified on surveillance imaging for a recurrence rate of 4.3% at a mean 18 (± 10) months after initial operation. Persistent dysphagia occurred in 13% (6/47) over the first year, which resolved after a single balloon dilation in 67% (4/6). Two patients elected for device removal due to dilation-refractory dysphagia and persistent reflux symptoms. CONCLUSION Concomitant magnetic sphincter augmentation and hiatal hernia repair in patients with gastroesophageal reflux disease and a moderate-sized hiatal hernia demonstrates durable subjective reflux control and an acceptable hiatal hernia recurrence rate at 1- to 2-year follow-up.

Abstract
We propose a new classification for esophagogastric junction (EGJ) incorporating both physiologic and morphologic characteristics. Additionally, we contrast it with the Chicago v 3.0 EGJ classification. With Institutional Review Board (IRB) approval, prospectively maintained database was queried to identify patients who underwent high-resolution manometry (HRM) and pH-study between October 2011 and October 2015. Patients with prior foregut intervention, pH study on acid suppression, esophageal dysmotility, or lower esophageal sphincter-crural diaphragm separation of >5 cm were excluded. We classified patients into three groups-Type-A: Complete overlap of lower esophageal sphincter-crural diaphragm (single high-pressure zone); Type-B: Double high-pressure zone with pressure inversion point (PIP) at or above lower esophageal sphincter; Type-C: Double high-pressure zone with PIP below lower esophageal sphincter. A total of 214 included patients were divided into Type-A (n = 101), Type-B (n = 32), and Type-C (n = 81). Abdominal lower esophageal sphincter length (AL), lower esophageal sphincter pressure (LESP), and lower esophageal sphincter pressure integral (LESPI) were significantly lower in Type-C than both Type-A and Type-B [AL(cm): 0.2 vs. 2(P < 0.001) vs. 1.6(P <0.001); LESP(mmHg): 20.1 vs. 32.1(P < 0.001) vs. 29.2(P < 0.001); LESPI(mmHg.cm.s): 187 vs. 412(P < 0.001) vs. 343(P < 0.05)] while overall lower esophageal sphincter length(OL) and Integrated Relaxation Pressure (IRP) were significantly lower in Type-C than Type-A [OL(cm): 2.9 vs. 3.6(P < 0.001); IRP(mmHg): 8.2 vs. 9.6(P < 0.05)]. Type-C patients had significantly higher positive pH score (>14.7) than Type-A and Type-B [72% vs. 47% (P < 0.05) vs. 41% (P < 0.001)]. In Type-C morphology, there is both anatomical and physiological deterioration, weakest lower esophageal sphincter function (abdominal length, lower esophageal sphincter pressure, and lower esophageal sphincter pressure integral) and is most likely to be associated with pathological reflux. This proposed classification incorporates both physiological and morphological derangements in a graded fashion.

Abstract
BACKGROUND The Chicago classification has recently added a morphological subclassification for the esophagogastric junction (EGJ). Our aim was to assess the distal esophageal acid exposure in patients with this new Chicago EGJ-type IIIa and IIIb classification. STUDY DESIGN From a prospectively collected high-resolution manometry (HRM) database, we identified patients who underwent 24-h pH study between October 2011 and June 2015 and were diagnosed with EGJ-type III based on HRM. Chicago EGJ-type III is defined as the inter-peak nadir pressure ≤gastric pressure and a lower esophageal sphincter (LES)-crural diaphragm (CD) separation >2 cm [IIIa-pressure inversion point (PIP) remains at CD level and IIIb-PIP remains at LES level]. We classified the patients into reflux group [DeMeester score >14.72 or Fraction time pH (<4) > 4.2 %] and non-reflux group based on 24-h pH study. RESULTS Fifty patients were identified that satisfied the study criteria, of which 37 patients (74 %) were EGJ-type IIIa. In those with EGJ-type IIIb, abdominal LES length (AL) in reflux group was significantly shorter than the non-reflux group (0.8 vs. 1.8, p < 0.05). EGJ-type IIIa patients showed significantly higher value for DeMeester score and Fraction time pH and more often had a positive pH study than EGJ-type IIIb patients (DeMeester score: 26.7 vs. 11.7, p < 0.05; Fraction time pH: 7.9 vs. 2.6, p < 0.05; positive pH study: 81.1 vs. 30.8 %, p < 0.001). Reflux was more common in LES-CD ≥ 3 cm than that in LES-CD < 3 cm (85 vs. 56.7 %, p < 0.05). CONCLUSION A subset of patients with >2-cm LES-CD separation (type IIIb) maintain a physiological intra-abdominal location of the EGJ and are less likely to have reflux. A LES-CD ≥ 3 cm seems to discern a hiatus hernia of clinical significance.

Abstract
This paper presents a novel minimally-invasive catheter-based acoustic interrogation device for real-time monitoring the dynamics of the lower esophageal sphincter (LES). Dysfunction of the LES could result gastrointestinal (GI) diseases, such as gastroesophageal reflux disease (GERD). A micro-oscillator actively emitting sound wave at 16 kHz is located at one side of the LES, and a miniature microphone is located at the other side of the LES to capture the sound generated from the oscillator. Thus, the dynamics of the opening and closing of the LES can be monitored. The device was tested in vitro by utilizing a custom-designed LES simulator, as well as in vivo in a pilot canine model. In the in vitro test, the sound was captured by the microphone and its strength was correlated with the level of LES opening and closing which was controlled by the simulator. The measurements showed statistically significant (p < 0.05) Pearson correlation coefficients (0.905 on the average in quiet environment and 0.736 on the average in noisy environment, DOF = 9). In the in vivo test, the LES was forced open and closed by a transoral endoscope, which was monitored in real-time by a transpyloric endoscope inserted from the duodenum and positioned into the distal stomach. Frame-by-frame video analysis validated the interrelation between the sound strength and the LES opening and closing. The LES dynamics monitored by the proposed device has the potential to become a valuable minimally-invasive technique for understanding LES dysfunction.

Abstract
BACKGROUND The role of esophagogastric junction contractile integral (EGJ-CI) as assessed by high-resolution manometry (HRM) is unclear. We aimed to correlate the EGJ-CI with impedance-pH findings in gastro-esophageal reflux disease (GERD) patients. METHODS Consecutive patients with GERD symptoms were enrolled. All patients underwent upper endoscopy, HRM, and impedance-pH testing. The EGJ-CI was calculated using the distal contractile integral tool box during three consecutive respiratory cycles. The value was then divided by the duration of these cycles. A value below 13 was considered as a defective EGJ-CI. We also assessed EGJ morphology, esophageal acid exposure time (AET), number of reflux episodes (NRE), and symptom association analysis (SAA). A positive impedance-pH monitoring was considered in case of abnormal AET and/or NRE and/or positive SAA. KEY RESULTS Among 130 patients we enrolled, 91 had GERD (abnormal AET and/or elevated NRE and/or positive SAA) and 39 had functional heartburn (FH) (negative endoscopy, normal AET, normal NRE, and negative SAA). The GERD patients had a lower median value of EGJ-CI (11 [3.1-20.7] vs 22 [9.9-41], p < 0.02) compared to FH patients. Patients with a defective EGJ-CI had, more frequently, a positive impedance-pH monitoring or esophageal mucosal lesions at endoscopy (p < 0.05 and p < 0.05, respectively) than patients with a normal EGJ-CI. An EGJ-CI cut-off value of 5 mmHg cm yielded the optimal performance in identifying GERD at impedance-pH (sensitivity 89%-specificity 63%). CONCLUSIONS & INFERENCES A defective EGJ-CI at HRM is clearly associated with evidence of GERD at impedance-pH monitoring. Evaluating EGJ-CI may be useful to predict an abnormal impedance-pH testing.

Abstract
INTRODUCTION To evaluate the clinical outcomes of laparoscopic floppy Nissen fundoplication (LNF) and laparoscopic Toupet fundoplication (LTF) for the treatment of gastroesophageal disease (GERD). METHODS A total of 84 patients with GERD were randomized to either LNF (n = 43) or LTF (n = 41) between January 2010 and January 2013. The primary endpoint measures were the DeMeester score, distal esophageal amplitude (DEA), peristaltic frequency, lower esophageal sphincter pressure (LESP), short-term and long-term postoperative dysphagia and recurrence rate. The secondary endpoints were improvements in symptom scores and quality of life (QoL), and perioperative complications. RESULTS LNF group had a lower DeMeester score and a higher LESP compared to LTF group after surgery (DeMeester score: P = 0.007; LESP: P = 0.027). The mean DEA and peristaltic frequency both improved significantly after surgery in 2 groups. There was no difference in the incidence of short-term adverse events (including dysphagia, heartburn, regurgitation et al.) between the two groups (P = 0.157). At the time of the latest follow-up, there was no difference in the incidence of symptomatic reflux symptom (heartburn and regurgitation) between the two groups (heartburn: P = 0.363; regurgitation: P = 1.000). A higher frequency of dysphagia was present in the LNF group compared with the LTF group (P = 0.023). DISCUSSION LNF is associated with an excessive elevation of LESP which may lead to further persistent dysphagia. Partial fundoplication may provide adequate reflux control, improve esophageal body motility and minimize complications associated with an 'over-tight' fundal wrap. CONCLUSION LTF seems to be as safe and effective on the long-term as LNF, but with a lower incidence of postoperative dysphagia (ChiCTR-TRC-13003945).

Abstract
Gastroesophageal reflux disease (GERD) is a frequent disorder which is expensive to diagnose and treat. Initiating therapy with empiric trial of proton-pump inhibitor is a well established strategy; however, symptoms of GERD do often persist regardless of effective medication. Nowadays, increasing interest concerning the efficacy and safety of chronic acid suppression with proton-pump inhibitors (PPIs), prompts a consideration for GERD treatment strategies related to the basic physiology of the lower esophageal sphincter, including modulation of its tone and ending of spontaneous transient lower esophageal sphincter relaxation, which contributes to reflux. Together, the lower esophageal sphincter and the crural diaphragm represent the major antireflux barrier, protecting the esophagus from reflux of gastric content. In order to prevent the need for enduring PPIs therapy or surgical procedures, substitute therapeutics approaches are being researched. Recently, studies have focused on the response of the respiratory muscles to inspiratory muscle training. As a result, inspiratory muscle training has emerged as a potential alternative for treatment of gastroesophageal reflux. The present report reviews the physiologic factors contributing to GERD, and presents the newly developed therapies that can be applied either alone or in association with available efficient GERD therapy.

Abstract
BACKGROUND The mechanism of reflux protection may involve a 'flap valve' at the oesophago-gastric junction (OGJ). AIM To assess the effects of baclofen, a gamma-aminobutyric acid receptor type-B (GABA-B) agonist known to suppress reflux events, on the 'functional anatomy' of the OGJ and proximal stomach after a large test meal. METHODS Twelve healthy volunteers (HVs) and 12 patients with gastro-oesophageal reflux disease (GERD); with erosive oesophagitis or pathological oesophageal acid exposure completed a randomised, double-blind, cross-over study. On 2 test days participants received 40-mg baclofen or placebo before ingestion of a large test meal. OGJ structure and function were assessed by high-resolution manometry (HRM) and magnetic resonance imaging (MRI) using validated methods. Measurements of the oesophago-gastric angle were derived from three-dimensional models reconstructed from anatomic MRI images. Cine-MRI and HRM identified postprandial reflux events. Mixed model analysis and Wilcoxon rank signed tests assessed differences between participant groups and treatment conditions. RESULTS In both HVs and GERD patients, baclofen reduced the frequency of postprandial reflux events. The oesophago-gastric insertion angle in GERD patients was reduced (-4.1 ± 1.8, P = 0.025), but was unchanged in healthy controls. In both study groups, baclofen augmented lower oesophageal sphincter (LES) pressure (HVs: +7.3 ± 1.8 mmHg, P < 0.0001, GERD: +4.50 ± 1.49 mmHg, P < 0.003) and increased LES length (HVs: +0.48 ± 0.11 cm, P < 0.0003, GERD: +0.35 ± 0.06 cm, P < 0.0001). CONCLUSIONS Baclofen inhibits transient LES relaxations and augments LES pressure and length. Additionally, baclofen has effects on the 'functional anatomy' of the OGJ and proximal stomach in GERD patients, which may suppress reflux by means of a 'flap valve' mechanism.

Abstract
BACKGROUND We previously demonstrated feasibility, safety, and a reproducible histologic bulking effect after injection of dextranomer hyaluronic acid copolymer (DxHA) into the gastroesophageal junction of rabbits. In the current study, we investigated the potential for DxHA to augment the lower esophageal sphincter (LES) in a porcine model of gastroesophageal reflux disease (GERD). METHODS Twelve Yucatan miniature pigs underwent LES manometry and 24-hour ambulatory pH monitoring at baseline, after cardiomyectomy, and 6weeks after randomization to endoscopic injection of either DxHA or saline at the LES. After necropsy, the foregut, including injection sites, was histologically examined. RESULTS Pigs in both groups had similar weight progression. Cardiomyectomy induced GERD in all animals, as measured by a rise in the median % of time pH <5 from 0.6 to 11.6 (p=0.02). Endoscopic injection of DxHA resulted in a higher median difference in LES length (1.8cm vs. 0.4cm, p=0.03). In comparison with saline injection, DxHA resulted in 120% increase in LES pressure, and 76% decrease in the mean duration of reflux episodes, but these results were not statistically significant. Injection of DxHA induced a foreign body reaction with fibroblasts and giant cells. CONCLUSIONS Porcine cardiomyectomy is a reproducible animal GERD model. Injection of DxHA may augment the LES, offering a potential therapeutic effect in GERD.

Abstract
OBJECTIVE To highlight the contributions from the University of Chicago under the leadership of Dr David B. Skinner to the understanding of gastroesophageal reflux disease (GERD) and its complications. BACKGROUND The invention of the esophagoscope confirmed that GERD was a premorbid condition. The medical world was divided between those who believed in a morphological lower esophageal sphincter (LES) and those who did not. Those who did not believe attempted to rearrange the anatomy of the foregut organs to stop reflux with minimal success. The discovery of the LES focused attention on the sphincter as the main deterrent to reflux and the hope that measurement of a low LES pressure would mark the presence of GERD. This turned out not to be so. In July 1973, with this history of confusion, Dr Skinner at the age of 36 assumed the chair of surgery at the University of Chicago. METHODS The publications of the University of Chicago's esophageal group were collected from private and public (PubMed) databases, reviewed, and seminal contributions selected. RESULTS Twenty-four-hour esophageal pH monitoring led to the understanding of the LES, its contribution to GERD, and the complication of Barrett's esophagus. The relationship of Barrett's to adenocarcinoma was clarified. The rising incidence of esophageal adenocarcinoma led to contributions in the staging of esophageal cancer and its treatment with an en bloc resection. CONCLUSIONS Ten years after the death of Dr Skinner, we can appreciate the monumental contributions to benign and malignant esophageal disease under his leadership.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is one of the most frequent benign disorders of the upper gastrointestinal tract. Management of GERD has always been controversial since modern medical therapy is very effective, but laparoscopic fundoplication is one of the few procedures that were quickly adapted to the minimal access technique. The purpose of this project was to analyze the current knowledge on GERD in regard to its pathophysiology, diagnostic assessment, medical therapy, and surgical therapy, and special circumstances such as GERD in children, Barrett's esophagus, and enteroesophageal and duodenogastroesophageal reflux. METHODS The European Association of Endoscopic Surgery (EAES) has tasked a group of experts, based on their clinical and scientific expertise in the field of GERD, to establish current guidelines in a consensus development conference. The expert panel was constituted in May 2012 and met in September 2012 and January 2013, followed by a Delphi process. Critical appraisal of the literature was accomplished. All articles were reviewed and classified according to the hierarchy of level of evidence and summarized in statements and recommendations, which were presented to the scientific community during the EAES yearly conference in a plenary session in Vienna 2013. A second Delphi process followed discussion in the plenary session. RESULTS Recommendations for pathophysiologic and epidemiologic considerations, symptom evaluation, diagnostic workup, medical therapy, and surgical therapy are presented. Diagnostic evaluation and adequate selection of patients are the most important features for success of the current management of GERD. Laparoscopic fundoplication is the most important therapeutic technique for the success of surgical therapy of GERD. CONCLUSIONS Since the background of GERD is multifactorial, the management of this disease requires a complex approach in diagnostic workup as well as for medical and surgical treatment. Laparoscopic fundoplication in well-selected patients is a successful therapeutic option.

Abstract
BACKGROUND Obesity and gastroesophageal reflux disease (GERD) are both high-prevalence diseases in developed nations. Obesity has been identified as an important risk factor in the development of GERD. The objective of this study was to determine the frequency of abnormal esophageal acid exposure in patients candidate for bariatric surgery and its relationship with any clinical and endoscopic findings before surgery. METHODS Data collected from a group of 88 patients awaiting bariatric surgery included a series of demographic variables and symptoms typical of GERD. The tests patients underwent included manometry, pH monitoring, and upper gastrointestinal endoscopy. Univariate and multivariate analyses were conducted on the variables related to the onset of reflux. RESULTS Esophageal pH monitoring tests were positive in 65% of the patients. Manometries showed lower esophageal sphincter hypotonia in 46%, while 20% returned abnormal upper endoscopy results. Out of the 45% of patients who were asymptomatic or returned normal endoscopies, half returned positive esophageal pH tests. In turn, among the 55% of patients who had symptoms or an abnormal upper endoscopy, three quarters had pH tests that diagnosed reflux. pH tests were also positive in 80% of symptomatic patients and 100% of patients with esophagitis (P<.042). No statistically significant relationship was found between body mass index, sex, age, manometry, or hiatus hernia and the positive pH monitoring. CONCLUSION Frequency of abnormal esophageal acid exposure among obese patients is high. There is a relationship between the presence of symptoms and reflux. But the absence of symptoms does not rule out the presence of abnormal esophageal function tests.

Abstract
Background Information about gastro-oesophageal reflux disease (GERD) in patients with Diabetes mellitus type 2 (T2D) is scarce, although the incidence of both disorders is increasing. We aimed to determine GERD symptoms and their underlying pathophysiologic characteristics in T2D patients. Methods This “retro-pro” study compared 65 T2D patients to a control group of 130 age- and sex-matched non-diabetics. GERD was confirmed by gastroscopy, manometry, pH-metry and barium swallow. Results In patients with T2D compared to controls, dysphagia (32.3% vs. 13.1%; p = 0.001) and globus sensation (27.7% vs. 13.8%; p = 0.021) were found more frequently, whereas heartburn (76.9% vs. 88.5%; p = 0.046) and regurgitation (47.7% vs. 72.3%; p = 0.001) were predominant in non-diabetics. Despite higher body mass indices (31.1 ± 5.2 vs. 27.7 ± 3.7 kg/m2; p < 0.001), hiatal hernia was less frequent in T2D patients compared to controls (60.0% vs. 90.8%, p < 0.001). Lower oesophageal sphincter (LES) pressure was higher in patients with T2D (median 10.0 vs. 7.2 mmHg, p = 0.016). DeMeester scores did not differ between the groups. Helicobacter pylori infections were more common in T2D patients (26.2% vs. 7.7%, p = 0.001). Barrett metaplasia (21.5% vs. 17.7%), as well as low- (10.8% vs. 3.8%) and high-grade dysplasia (1.5% vs. 0%) were predominant in T2D patients. Conclusions T2D patients exhibit different GERD symptoms, higher LES pressures and a decreased prevalence of hiatal hernia than non-diabetics, which may be related to worse oesophageal motility and, thus, a more functional rather than anatomical cause of GERD. Low-grade dysplasia was more than twice as high in T2D than in non-diabetics patients. Trial registration Ethics committee of the Medical University of Vienna, IRB number 720/2011.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a very prevalent disorder. Medical therapy improves symptoms in some but not all patients. Antireflux surgery is an excellent option for patients with persistent symptoms such as regurgitation, as well as for those with complete symptomatic resolution on acid-suppressive therapy. However, proper patient selection is critical to achieve excellent outcomes. STUDY DESIGN A panel of experts was assembled to review data and personal experience with regard to appropriate preoperative evaluation for antireflux surgery and to construct an evidence and experience-based consensus that has practical application. RESULTS The presence of reflux symptoms alone is not sufficient to support a diagnosis of GERD before antireflux surgery. Esophageal objective testing is required to physiologically and anatomically evaluate the presence and severity of GERD in all patients being considered for surgical intervention. It is critical to document the presence of abnormal distal esophageal acid exposure, especially when antireflux surgery is considered, and reflux-related symptoms should be severe enough to outweigh the potential side effects of fundoplication. Each testing modality has a specific role in the diagnosis and workup of GERD, and no single test alone can provide the entire clinical picture. Results of testing are combined to document the presence and extent of the disease and assist in planning the operative approach. CONCLUSIONS Currently, upper endoscopy, barium esophagram, pH testing, and manometry are required for preoperative workup for antireflux surgery. Additional studies with long-term follow-up are required to evaluate the diagnostic and therapeutic benefit of new technologies, such as oropharyngeal pH testing, multichannel intraluminal impedance, and hypopharyngeal multichannel intraluminal impedance, in the context of patient selection for antireflux surgery.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is the most prevalent gastrointestinal disorder in the USA. Heartburn is the symptom most commonly associated with this disease, and the highly commercialized medical treatment directed toward relief of this symptom represents a 10-billion-dollar-per-year industry. DISCUSSION Unfortunately, there is often little awareness that GERD can be potentially a lethal disease as it can cause esophageal cancer. Furthermore, there is even less awareness about the relationship between GERD and respiratory disorders with the potential for severe morbidity and even mortality.

Abstract
BACKGROUND Differences in lower esophageal sphincter (LES) and peristaltic function and in transient LES relaxations (TLESR) have been described in patients with gastro-esophageal reflux disease (GERD). However, some of these differences may be the result of chronic GERD rather than being an underlying contributory factor. METHODS Twins discordant for GERD symptoms, i.e., only one twin had GERD symptoms, underwent standard LES and esophageal body manometry, and then using a sleeve sensor prolonged LES and pH monitoring, 30 min before and 60 min after a 250 mL 1200 kcal lipid meal. KEY RESULTS Eight monozygotic and 24 dizygotic female twins were studied. Although there was no difference in preprandial LES pressure (symptomatic 13.2 ± 7.1 mmHg vs asymptomatic 15.1 ± 6.2 mmHg, P = 0.4), LES pressure fell further postprandially in symptomatic twins (LES pressure area under the curve 465 ± 126 vs 331 ± 141 mmHg h, P < 0.01). 12/37 (32%) of acid reflux episodes in symptomatic twins occurred due to low LES pressure or deep inspiration/strain and 0/17 in asymptomatic twins (P = 0.01). There was no difference between symptomatic and asymptomatic twins in: peristaltic amplitude, ineffective esophageal body motility, hiatus hernia prevalence, or LES length. There was also no difference in TLESR frequency preprandially (symptomatic median 1(range 0-2) vs asymptomatic 0(0-2), P = 0.08) or postprandially (2.5(1-8) vs 3(1-6), P = 0.81). CONCLUSIONS & INFERENCES Twins with GERD symptoms had lower postprandial LES pressure and given the close genetic link between the twins, it is possible that such differences are caused by GERD. Acid reflux episodes associated with a hypotensive LES were seen in symptomatic, but not in asymptomatic twins.

Abstract
BACKGROUND The importance of endoscopic evaluation and grading of the gastroesophageal flap valve (GEFV) in patients with gastroesophageal reflux disease (GERD) was previously demonstrated with increased acid exposure and high grades of esophagitis in those with high-grade valves. On the other hand, no data exist on the relationship between GEFV appearance and surgical rate. METHODS For 453 patients with symptoms suggestive of GERD, GEFV grading and 24-h ambulatory pH monitoring were performed. Surgery was performed for 82 of these patients who failed medical management or had disease complications. RESULTS The GEFV grade 4 patients were younger than the patients with normal GEFV (grades 1 [p = 0.017] and 2 [p < 0.001]) and showed significant male predominance. The prevalence of hiatal hernia, the degree of esophageal acid exposure, and the prevalence and degree of erosive esophagitis significantly increased with GEFV grade (p < 0.001 for all). No GEFV grade 1 patients underwent surgery compared with 4.9 % of the grade 2 patients, 20.5 % of the grade 3 patients, and 63.6 % of the grade 4 patients who had surgery for various indications (p < 0.001). CONCLUSIONS Esophagogastric opening estimated by endoscopic grading of the GEFV was strongly correlated with surgery rate in GERD patients. In particular, patients with grade 4 valves showed the highest rates of erosive esophagitis and axial hiatal hernia and frequently underwent surgery for either failed medical management or disease complications.

Abstract
BACKGROUND Inspiratory muscle training (IMT) has been shown to increase diaphragm thickness. We evaluated the effect of IMT on mid-respiratory pressure (MRP) in patients with gastroesophageal reflux disease (GERD) and hypotensive lower esophageal sphincter (LES), and compared the results with a sham group. METHODS Twenty consecutive patients (progressive loading group) and 9 controls (sham group) were included. All patients had end expiratory pressure (EEP) between 5 and 10 mmHg, underwent esophageal manometry and pulmonary function tests before and after 8 weeks of training, and used a threshold IMT twice daily. The threshold IMT was set at 30% of the maximal inspiratory pressure for the progressive loading group; while, the threshold for sham-treated patients was set at 7 cmH(2)O for the whole period. RESULTS There was an increase in MRP in 15 (75%) patients in the progressive loading group, with an average gain of 46.6% (p < 0.01), and in six (66%) patients in the sham group with a mean increase of 26.2% (p < 0.01). However, there was no significant difference between the groups (p = 0.507). The EEP also increased compared with measurements before training (p < 0.01), but it did not differ between groups (p = 0.727). CONCLUSION IMT increased LES pressure in patients with GERD, in both the treatment and sham groups, after an eight-week program. Although there was no statistically significant difference between groups, suggesting the pressure increase in LES occurs regardless of the resistance load of the threshold IMT. These findings need to be confirmed in further studies with a larger sample. REGISTRATION NUMBER 0922/09.
