Abstract
INTRODUCTION The incidence of obesity is increasing in developed societies, and surgical treatment is one treatment option. The most common surgical treatment for obesity is laparoscopic sleeve gastrectomy (LSG). Gastroesophageal reflux disease (GERD) is a complication of both obesity and the surgical treatment of obesity. MATERIALS AND METHODS In this study, the PubMed database was searched using the keywords "GERD" and "bariatric surgery", and 987 papers published between 1 July 2017 and 30 June 2022 were retrieved. RESULTS Nine papers met the inclusion criteria and were included in the meta-analysis. The articles were analyzed for the de novo occurrence of GERD after the treatment of its symptoms, the occurrence of erosive esophagitis, and Barrett's esophagus. In addition, interesting conclusions are presented from the papers that did not meet the inclusion criteria but shed light on the pathophysiology of GERD in obese patients undergoing LSG. CONCLUSION In conclusion, the authors draw attention to the need for endoscopic surveillance in patients undergoing LSG, even in the absence of clinical signs of GERD.

Evaluating agreement between clinic- and patient-reported outcomes for weight and co-morbidities at 1 year after bariatric surgery. Surg Obes Relat Dis 2023; 19:309-317. [PMID: 36400692 DOI: 10.1016/j.soard.2022.10.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Revised: 09/21/2022] [Accepted: 10/03/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND Development of patient-reported outcomes (PROs) to include traditionally clinic-reported data has the potential to decrease the data-collection burden for patients and clinicians and increase follow-up rates. However, replacing clinic report by patient report requires that the data reasonably agree. OBJECTIVE To assess agreement between PROs and clinical registry data at 1 year after bariatric surgery. SETTING Not-for-profit organization, bariatric surgery data registry, PROs platform. METHODS Patient- and clinic-reported 1-year postoperative weight and co-morbidities were compared for matched PROs and registry records. The co-morbidities evaluated were diabetes, sleep apnea, hypertension, gastroesophageal reflux disease, and hyperlipidemia. Weight difference in pounds and nominal groupings (binary, 4-level) for co-morbidities were assessed for agreement between data sources using descriptive statistics, Bland-Altman plots, multiple regression, and kappa coefficients. Sensitivity analyses and follow-up by response method were examined. RESULTS Among 1130 patients with both 1-year PROs and registry weights, 95% of patient-reported weights were within 13 lb of the registry-recorded weight, and patients underreported their weight by ∼2 lb, on average. Percent agreement and kappa coefficients were highest for diabetes (n = 999; binary: 94%, κ = .72; 4-level: 86%, κ = .71) and lowest for gastroesophageal reflux disease (n = 1032; binary: 75%, κ = .40; 4-level: 57%, κ = .35). Of patients eligible for both PROs and registry 1-year follow-up, 21% had PROs only. CONCLUSIONS One-year patient- and clinic-reported weights and disease status for patients with diabetes and hypertension showed high agreement. The degree of bias from patient report was low. Patient report is a viable alternative to clinic report for certain objective measurements and may increase follow-up.

Abstract
Background Gastroesophageal reflux disease (GERD) is a chronic disease mainly characterized by heartburn and acid regurgitation. To our knowledge, there have been a limited number of studies in Saudi Arabia looking at the knowledge level among the general population regarding this disease and its associated factors. Therefore, this study aims to identify the knowledge level of the disease and its associated factors, assess the prevalence of GERD among the Riyadh general population, and assess the need for educational programs for GERD. Methodology A cross-sectional study was conducted among the general public in Riyadh, Saudi Arabia. The degree of GERD knowledge was assessed by translating and editing Jorgen Urnes' 24-item questionnaire into Arabic. In addition, six questions related to the symptoms and complications of GERD were added. Convenience sampling was done by using a Google form to distribute the questionnaire. The questionnaire assesses GERD knowledge by asking about the signs, symptoms, risk factors, predisposing factors, and management of GERD. Statistical analysis was performed using R v. 3.6.3 (https://cran.r-project.org/bin/windows/base/old/3.6.3/). Counts and percentages were used to summarize the distribution of categorical variables. Results The questionnaire was completed by 664 respondents (48.2% males and 51.8% females). The average age of the included respondents was 34.1 ± 12.8 years and Saudis represented 97% of the included respondents. The majority of the respondents had heard of GERD (83%). The average number of correct answers was 12.7 ± 6.1. In total, 40 respondents did not answer any questions correctly. Approximately one-third of respondents answered >50% of the questions correctly (n = 250, 37.6%). Approximately half of the respondents identified all risk factors for GERD. Other common risk factors identified included caffeine (23.6%), fast food (26.8%), and smoking (17.6%). Slightly more than a quarter of the respondents reported being diagnosed with GERD (28.8%). Knowledge was significantly higher among respondents who had received a diagnosis of GERD. A statistically significant positive association was observed between age and knowledge (r = 0.19, p < 0.001). Conclusion The study shows a relatively good knowledge level compared to previously reported figures in Saudi Arabia and worldwide. Educational programs for GERD should be increased in Saudi Arabia and more health conferences and teaching school students of the disease should be highlighted to increase the general knowledge of this disease in the Kingdom of Saudi Arabia (KSA).

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18126189. [PMID: 34201073 PMCID: PMC8227586 DOI: 10.3390/ijerph18126189] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Revised: 06/06/2021] [Accepted: 06/07/2021] [Indexed: 12/12/2022]
Abstract
This cross-sectional study investigated the relationship between shift work and reflux esophagitis verified by endoscopic findings. Participants underwent a comprehensive health examination and esophagogastroduodenoscopy between January 2011 and December 2018. We examined endoscopic findings and performed multivariate-adjusted regression analysis of the association between shift work and reflux esophagitis using multiple demographic and clinical factors. Among the 247,450 participants, 49,767 (20.1%) had reflux esophagitis; Los Angeles (LA)-M (31,132, 12.6%) was most common, followed by LA-A (16,213, 6.6%), LA-B (2333, 0.9%), and ≥LA-C (89, 0.04%). The multivariate-fully adjusted odds ratio (OR) of overall reflux esophagitis for shift work compared to fixed day work was 1.15 (95% confidence interval [CI]: 1.11–1.19). When classified according to shift work type and severity of reflux esophagitis, the ORs of LA-A for regular day and night, and irregular shifts compared to fixed day works were 1.14 (95% CI: 1.03–1.26) and 1.26 (95% CI: 1.11–1.44), respectively. However, there was no significant association between any shift work schedule and ≥LA-B. Overall, we demonstrated the cross-sectional association between shift work (especially rotating and irregular shifts) and mild reflux esophagitis (≤LA-A) compared with daily fixed time shifts.

Syst Rev 2020; 9:20. [PMID: 31996261 PMCID: PMC6990541 DOI: 10.1186/s13643-020-1275-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Accepted: 01/07/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Two reviews and an overview were produced for the Canadian Task Force on Preventive Health Care guideline on screening for esophageal adenocarcinoma in patients with chronic gastroesophageal reflux disease (GERD) without alarm symptoms. The goal was to systematically review three key questions (KQs): (1) The effectiveness of screening for these conditions; (2) How adults with chronic GERD weigh the benefits and harms of screening, and what factors contribute to their preferences and decision to undergo screening; and (3) Treatment options for Barrett's esophagus (BE), dysplasia or stage 1 EAC (overview of reviews). METHODS Bibliographic databases (e.g. Ovid MEDLINE®) were searched for each review in October 2018. We also searched for unpublished literature (e.g. relevant websites). The liberal accelerated approach was used for title and abstract screening. Two reviewers independently screened full-text articles. Data extraction and risk of bias assessments were completed by one reviewer and verified by another reviewer (KQ1 and 2). Quality assessments were completed by two reviewers independently in duplicate (KQ3). Disagreements were resolved through discussion. We used various risk of bias tools suitable for study design. The GRADE framework was used for rating the certainty of the evidence. RESULTS Ten studies evaluated the effectiveness of screening. One retrospective study reported no difference in long-term survival (approximately 6 to 12 years) between those who had a prior esophagogastroduodenoscopy and those who had not (adjusted HR 0.93, 95% confidence interval (CI) 0.58-1.50). Though there may be higher odds of a stage 1 diagnosis than a more advanced diagnosis (stage 2-4) if an EGD had been performed in the previous 5 years (OR 2.27, 95% CI 1.00-7.67). Seven studies compared different screening modalities, and showed little difference between modalities. Three studies reported on patients' unwillingness to be screened (e.g. due to anxiety, fear of gagging). Eleven systematic reviews evaluated treatment modalities, providing some evidence of early treatment effect for some outcomes. CONCLUSIONS Little evidence exists on the effectiveness of screening and values and preferences to screening. Many treatment modalities have been evaluated, but studies are small. Overall, there is uncertainty in understanding the effectiveness of screening and early treatments.

Abstract
INTRODUCTION Medical therapy of gastroesophageal reflux disease (GERD) is based on the use of proton pump inhibitors (PPIs) as first choice treatment. Despite their effectiveness, about 20-30% of patients report an inadequate response and alternative drugs are required. Areas covered: This review provides an overview of current pharmacotherapy for treating GERD by showing the results of PPIs, reflux inhibitors, antidepressants and mucosa protective medications. Expert opinion: Medical therapy of GERD does not definitely cure the disease, because even PPIs are not able to change the key factors responsible for it. However, they remain the mainstay of medical treatment, allowing us to alleviate symptoms, heal esophagitis and prevent complications in the majority of cases. Nevertheless, many patients do not respond, because acid does not play any pathogenetic role. Prokinetics and reflux inhibitors have the potential to control motor abnormalities, but the results of clinical trials are inconsistent. Antidepressant drugs are effective in specific subgroups of NERD patients with visceral hypersensitivity, but larger, controlled clinical studies are necessary. Protective drugs or medical devices have been recently adopted to reinforce mucosal resistance and preliminary trials have confirmed their efficacy either combined with or as add-on medication to PPIs in refractory patients.

Abstract
Esophageal and gastroesophageal junction (GEJ) diseases are highly prevalent worldwide and are a significant socioeconomic burden. Recently, applications of multiscale mathematical models of the upper gastrointestinal tract have gained attention. These in silico investigations can contribute to the development of a virtual esophagus modeling framework as part of the larger GIome and Physiome initiatives. There are also other modeling investigations that have potential screening and treatment applications. These models incorporate detailed anatomical models of the esophagus and GEJ, tissue biomechanical properties and bolus transport, sensory properties, and, potentially, bioelectrical models of the neural and myogenic pathways of esophageal and GEJ functions. A next step is to improve the integration between the different components of the virtual esophagus, encoding standards, and simulation environments to perform more realistic simulations of normal and pathophysiological functions. Ultimately, the models will be validated and will provide predictive evaluations of the effects of novel endoscopic, surgical, and pharmaceutical treatment options and will facilitate the clinical translation of these treatments.

Abstract
We recommend that uncomplicated GERD be diagnosed on the basis of typical symptoms without the use of diagnostic testing, including EGD. We recommend EGD for patients who have symptoms suggesting complicated GERD or alarm symptoms. We recommend that EGD not be routinely performed solely for the assessment of extraesophageal GERD symptoms. We recommend that endoscopic findings of reflux esophagitis be classified according to an accepted grading scale or described in detail. We suggest that repeat EGD be performed in patients with severe erosive esophagitis after at least an 8-week course of PPI therapy to exclude underlying BE or dysplasia. 44BB We recommend against obtaining tissue samples from endoscopically normal tissue to diagnose GERD or exclude BE in adults. We suggest that endoscopy be considered in patients with multiple risk factors for Barrett’s esophagus. We recommend that tissue samples be obtained to confirm endoscopically suspected Barrett’s esophagus. We suggest that endoscopic antireflux therapy be considered for selected patients with uncomplicated GERD after careful discussion with the patient regarding potential adverse effects, benefits, and other available therapeutic options.

Abstract
BACKGROUND AND AIM Few data describing short-term proton pump inhibitor (PPI) treatment in patients with globus sensation exist. The aim of this study was to evaluate the use of high-resolution manometry (HRM) for predicting the response to PPI treatment in patients with globus sensation. METHOD A total of 41 patients with globus sensation were treated with PPIs for 4 weeks and were classified as positive and negative responders. HRM topographical plots were analyzed for relevant manometric parameters. In addition, clinical and HRM data of 20 patients with typical gastroesophageal reflux disease (GERD) not presenting globus symptom were analyzed. RESULTS Of the 41 patients, 19 (46%) were clinically diagnosed with GERD. The proportion of patients with favorable symptomatic improvement was higher in patients with GERD than in those without reflux (P=0.046). Positive and negative responders to PPI treatment did not differ in upper esophageal sphincter and proximal esophageal contraction. In globus patients with GERD, the temporal and spatial dimension of the transitional zone were greater among negative responders than among PPI-positive responders (P=0.010 and P=0.011). Regarding GERD patients without globus, there was no significant difference in transition zone defect according to PPI responsiveness. By receiver operating characteristic curve analysis, 2.1 cm and 1.1 s were found to be the spatial and temporal transitional zone dimensions that best differentiated positive and negative responders. CONCLUSION In patients with GERD-related globus, there were larger transition zone defect in the negative responders compared with the PPI-positive responders.

Abstract
BACKGROUND While there is evidence of ethnic variation in the prevalence of gastro-oesophageal reflux disease (GERD) symptoms, few population-based studies examine GERD symptom prevalence amongst the growing Hispanic minority in the US as well as Asians in the West. AIM To examine the prevalence, awareness and care patterns for GERD across different ethnic groups. METHODS A population-based, cross-sectional survey was fielded in English, Chinese and Spanish that assessed self-reported GERD prevalence, awareness and care patterns in four ethnic groups (Caucasian, African American, Asian, Hispanic). RESULTS A total of 1172 subjects were included for analysis: 34.6% experienced GERD symptoms at least monthly, 26.2% at least weekly and 8.2% at least daily. Statistically significant differences in raw prevalence rates between racial groups were found: 50% of Hispanics experienced heartburn at least monthly, compared with 37% of Caucasians, 31% of African Americans and 20% of Asians (P > 0.0001). Significant differences in knowledge and care-seeking patterns by ethnicity were also observed. CONCLUSIONS This study confirms the high prevalence of GERD symptoms in the US and introduces Hispanics as the ethnicity with the highest prevalence rate. Asians in the US have higher rates of symptoms than in the Far East. These data demonstrate a need for culturally appropriate education about GERD symptoms and treatment.

Abstract
BACKGROUND AND AIM We compared endoscopic findings of the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG), a written questionnaire developed in Japan, to that for the questionnaire for the diagnosis of reflux esophagitis (QUEST) for the diagnosis of reflux esophagitis. METHODS We registered 475 patients with untreated symptoms of upper abdominal pain (male/female: 252/223, average age 52.4 +/- 17.8 years). Subjects were assessed first with the FSSG and QUEST questionnaires, then by endoscopy, before allocation to a gastric ulcer (GU), duodenal ulcer (DU), gastroesophageal reflux disease (GERD) or functional dyspepsia (FD) group. RESULTS On the basis of the endoscopic findings the diagnoses for the 475 subjects were as follows: FD 52.2%, DU 7.6%, GU 7.8%, and GERD 32.4% (Grade M 10.1%, Grade A + B 20.2%, Grade C + D 2.3%). There was no difference between the FSSG and QUEST in sensitivity, specificity or accuracy for any condition. The FSSG score rose with increasing endoscopic severity of GERD, but there was no correlation between the QUEST score and endoscopic severity. The FSSG total score was inferior to QUEST in terms of distinguishing GERD from other conditions, but when only the questions relating to reflux symptoms were used, the FSSG was able to distinguish GERD from other conditions as well as QUEST. CONCLUSIONS The FSSG score reflects the severity of the endoscopic findings of GERD.

Abstract
BACKGROUND We aimed to determine the prevalence of gastroesophageal reflux disease (GERD) and associated risk factors, and assess quality of life (QoL) in relation to the frequency and severity of reflux symptoms. METHODS A random sample of 1000 residents of Western Sydney were mailed a validated self-report questionnaire. GERD symptoms, risk factors, psychologic distress, QoL, and demographics were measured. RESULTS The response rate was 73% (n=672; mean age, 46 y; 52% female). A total of 78 [12%, 95% confidence interval (CI): 9-14] had GERD (at least weekly heartburn and/or acid regurgitation). Independent risk factors for GERD were high cholesterol [odds ratio (OR) =3.28, 95% CI: 1.42-7.57, P=0.005] and current smoker (OR=2.47, 95% CI: 1.07-5.70, P=0.03). Anxiety, depression, and neuroticism were not risk factors. Worse physical functioning was the only QoL domain associated with GERD (OR=0.98, 95% CI: 0.97-0.99, P=0.006). QoL was significantly impaired regardless of the severity of GERD for the QoL domains physical function, body pain, vitality, and social function. The frequency of heartburn and acid regurgitation were not associated with significantly reduced QoL domain scores. CONCLUSIONS Cardiac risk factors (high cholesterol and smoking) were independently associated with GERD. Increasing GERD symptom severity is associated with worse QoL scores, whereas GERD symptom frequency did not impact the QoL scores.

Abstract
OBJECTIVE To analyse the incremental medical care cost of gastro-oesophageal acid-related disease (GERD), and its interactive effects with other diagnoses. METHODS A retrospective cohort study was conducted. Six hundred GERD patients were randomly selected and 600 non-GERD patients were selected, matched by age, gender, prescription pharmaceutical benefits and insurance status. Information on demographics, direct medical care cost (DMC) (inpatient, ambulatory and pharmaceuticals) and health service utilization was obtained from a large, not-for-profit managed-care organization across 3 years (1996-1998). DMCs were compared between GERD and non-GERD groups using the bootstrap method. Random coefficient log linear regression models were used to analyse incremental cost and assess its association with other diagnoses. RESULTS The mean annual DMC for the GERD group was $4906, as compared to $2054 for the non-GERD group. The increase in the DMC in the GERD group was attributable to increased co-morbidity. Age and gender had no effect on total cost for the GERD population. Among costs of services, the GERD group had a 2.00-fold higher cost associated with outpatient services, a 1.70-fold higher cost associated with inpatient services, and a 2.70-fold higher cost associated with pharmacy. CONCLUSIONS GERD is a chronic disease often associated with other diagnoses that significantly affect total DMC. Although the direct cost of treating GERD is low, patients with GERD had significantly higher total medical care cost than those without GERD. The addition of one more disease to a person's existing group of diseases has an important long-term health cost impact.

Abstract
Histology in reflux disease is still regarded as having low sensitivity and specificity. During the last three decades several histological parameters have been developed, including thickness of basal cell layer, length of epithelial papillae, intraepithelial inflammatory cells and dilation of intercellular spaces. Unfortunately classification of these parameters was often not related to the clinical symptoms of the reflux affected individuals, proper control subjects were often missing and often no interobserver variation was given. Another reason for the proposed low value of biopsies is the fact that biopsies were often taken in a non-standardised way. Recent studies point towards an area of predominantly epithelial damage close to the lesser curvature or around the right oesophageal wall. In parallel, some large, careful studies carried out recently showed a good correlation with the clinical picture of reflux disease due to a standardised biopsy protocol and proper controls. But biopsies are not recommended in all routine classical cases of reflux disease since it is believed that little further information in addition to endoscopy can be obtained. However, histology can deliver much more information than the diagnosis of reflux induced lesions (e.g. the exclusion of malignancy or other oesophageal diseases).

Abstract
BACKGROUND Gastroesophageal reflux disease patients demonstrate various pathophysiologic backgrounds. Therefore, a heterogeneous response to proton-pump inhibitor (PPI) treatment can be expected. We investigated the effect of short-term PPI treatment on symptoms and quality of life (QOL) in primary care patients with and without pathologic esophageal acid exposure and in presence or absence of a positive association between symptoms and reflux episodes. STUDY Seventy-four heartburn patients were categorized into 4 groups according to positive or negative symptom-reflux association, as expressed in symptom index, symptom sensitivity index, and symptom association probability (SAP) and presence or absence of pathologic reflux, defined as esophageal pH<4%>6% of the time (pH+/pH-). Overall and specific reflux symptoms were assessed 1 week before and the last week during a 2-week course of 40-mg esomeprazole daily. The QOL was scored by the Quality of Life in Reflux and Dyspepsia questionnaire 2 weeks before treatment and directly after. RESULTS Using the SAP to assess symptom-reflux associations, the 4 groups [SAP+pH+(n=40); SAP+pH-(n=12); SAP-pH+(n=10); SAP-pH-(n=10)] had similar demographic characteristics. The SAP-pH- subgroup had the least overall symptom reduction (P<0.01) and in the SAP+pH+ subgroup the greatest heartburn symptom reduction was found (P<0.02). The residual symptom scores on treatment were lowest in SAP+pH+ and highest in SAP-pH- subgroups and relatively high in the SAP+pH-. QOL was severely reduced and SAP-pH- patients had the lowest QOL overall. Similar findings were made using symptom index and symptom sensitivity index. CONCLUSIONS Symptomatic reflux patients without evidence of reflux disease on a 24-hour pH recording responded less favorably to PPI treatment than patients with a positive symptom-reflux association or with pathologic reflux.

Abstract
BACKGROUND AND AIMS The relationship between hiatus hernia and reflux esophagitis is well established. However, there are conflicting reports regarding its effect on the development of nonerosive reflux disease (NERD). Our aim was to investigate the prevalence and axial length of hiatus hernia in patients with NERD, compared with patients with reflux esophagitis, Barrett esophagus, and controls. METHODS Axial hernia length of the diaphragmatic hiatus was measured prospectively at endoscopy in controls and patients with typical reflux symptoms occurring at least weekly during the last month relieved by antacids. RESULTS A final diagnosis of hiatus hernia was established in 21.2% of 249 controls, 60.4% of 346 patients with NERD, 78.1% of 251 patients with reflux esophagitis, and 88.2% of 17 patients with Barrett esophagus. Patients aged >59 years were most likely to have a hiatus hernia. There was an increased prevalence in patients with NERD as compared with controls (P<0.0001), and decreased prevalence as compared with those with reflux esophagitis and Barrett esophagus (P<0.0001 and 0.02, respectively). Axial length of hiatus hernia >3 cm was found more frequently in patients with reflux esophagitis and Barrett esophagus as compared with patients with NERD (P<0.0001 and 0.0052, respectively). There was no statistical significant difference between controls and patients with NERD regarding the prevalence of hiatus hernia >3 cm (P=0.0904). CONCLUSIONS A small (<3 cm) hiatus hernia may contribute to the development of NERD, whereas an axial length >3 cm is associated with a more severe disease.

Abstract
GOALS To investigate the features of nonerosive reflux disease (NERD). BACKGROUND NERD is not considered as a milder form of erosive gastro-esophageal reflux disease (eGERD). Although the prevalence of NERD was reported to be high in our country, there have been very few studies about NERD. STUDY We performed upper gastrointestinal endoscopy to confirm the diagnosis of GERD. The modified acid perfusion test and saline perfusion test were performed in 7 control subjects, 14 NERD, and 11 eGERD patients. The stimulus-response function to acid and saline was quantified by the duration of typical symptom perception (minutes), total sensory intensity rating (0 to 10), and the perfusion sensory score (SS), which was defined as the product of minutes and the sensory intensity rating. RESULTS The mean value of SS by saline was 0 in control subjects, 12.0 in NERD patients, and 1.5 in eGERD patients (P<0.01 control vs. NERD, P<0.01 NERD vs. eGERD). The mean SS with acid was 0.9 in control subjects, 52.5 in NERD patients, and 23.0 in eGERD patients (P<0.01 control vs. NERD, control vs. eGERD, P<0.05 NERD vs. eGERD). A statistically significant association was shown between the acid and saline perfusion SSs with a correlation coefficient value of r=0.57 in the NERD group (P<0.05). CONCLUSIONS Both eGERD and NERD, but especially NERD, exhibited esophageal hypersensitivity not only to acid but also saline perfusion, suggesting that hyperalgesia to acid and other factors (eg, psychologic and/or autonomic nerve disturbance) may play some roles in symptom generation in NERD.

Abstract
Gastro-oesophageal reflux disease (GORD) is mainly diagnosed on symptoms and endoscopy findings. At least 50% of patients with GORD will have a normal oesophagus at endosopy. Twenty four-hour ambulatory pH monitoring together with manometry offers an accurate objective diagnosis of GORD and is helpful in directing appropriate treatments including surgery.

Abstract
PURPOSE OF REVIEW The aim of this article is to identify and to balance the arguments in favor of and against lumping together gastroesophageal reflux disease and functional dyspepsia. RECENT FINDINGS In at least half of the patients diagnosed with gastroesophageal reflux disease no organic abnormalities are found. Hypersensitivity of the esophagus to various stimuli plays a key role in the genesis of symptoms in these patients. The association between symptoms and acid reflux events can be quantified by 24-h esophageal pH monitoring. It has also become possible to detect non-acid reflux, using the intraluminal impedance monitoring technique. Functional dyspepsia is still defined by a combination of symptoms for which no organic cause can be found. No positive diagnostic tools have yet become available and treatment with acid secretion inhibitors, Helicobacter pylori eradication or prokinetic drugs remains marginally effective. SUMMARY Gastroesophageal reflux disease is a well defined disease which can be diagnosed objectively with endoscopy or 24-h pH/impedance monitoring with symptom association analysis. Functional dyspepsia is a functional disorder for which no objective test has yet been discovered. Treatment of gastroesophageal reflux disease is based on objectively identified abnormalities and highly effective. Treatment of functional dyspepsia is empiric and marginally effective. For these reasons, the lumping together of gastroesophageal reflux disease and functional dyspepsia is not to be advised.

Abstract
BACKGROUND Little is known about the distinctive characteristics of subjects with frequent (at least weekly) and occasional gastro-oesophageal reflux symptoms. AIM To compare the characteristics and disease management of subjects complaining of at least weekly and less frequent gastro-oesophageal reflux symptoms. METHODS Population-based postal survey carried out in France in 2003 among a representative sample of 8000 subjects. RESULTS The prevalence of frequent and occasional gastro-oesophageal reflux symptoms was 7.8% and 23.4%, respectively. Compared to subjects with occasional gastro-oesophageal reflux symptoms, those with frequent symptoms were older, suffered from more severe symptoms and felt greater impact on daily living, despite a slightly shorter duration of symptoms. These subjects more often sought medical advice. Most of them had treated the last episode of symptoms primarily with a proton-pump inhibitor and less often with antacids/alginates. The degree of treatment satisfaction was lower in subjects with frequent gastro-oesophageal reflux symptoms, in relation to a more frequently observed persistence of symptoms irrespective of the medication used except for proton-pump inhibitors. CONCLUSIONS This survey suggests that subjects complaining of frequent or occasional gastro-oesophageal reflux symptoms constitute two distinctive groups. Despite greater healthcare use, the former group shows a lower level of satisfaction with disease management. Nevertheless, a substantial subset of subjects with occasional symptoms also complained of impaired health-related quality of life and sought health care.
