Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) in the long term reduces the quality of life, leading to digestive diseases. The present study aims to determine the risk factors for GERD. METHOD This study was conducted on 9,631 adults aged 35-65 years. The demographic characteristics, behavioral habits, nutritional intake, physical activity, anthropometric indices, and GERD data were extracted from the databank related to the Ravansar non-communicable diseases (RaNCD). Statistical analysis was performed using logistic regression models. RESULTS The prevalence of GERD was 10.99% (n = 1,058). The GERD was higher among older age and women. After adjusting for age and sex, the odds of GERD among current smokers was 23% higher than non-smokers. Drinking increased odds of GERD (OR: 1.51; 95% CI: 1.13, 1.99). The odds of GERD among depressed individuals were 46% higher than non-depressed. In addition, a significant relationship was observed between the high intake of sweets and desserts with increased GERD (OR: 1.02, 95% CI: 1.01, 1.03). Further, high intake of fiber (OR: 0.98, 95% CI: 0.97, 0.99) and dairy (OR: 0.99, 95% CI: 0.98, 0.99) was related to reducing the odds of GERD. Furthermore, a significant relationship was reported between the waist hip ratio (WHR) and visceral fat area (VFA) with increased odds of GERD. Finally, the physical activity level was inversely related to GERD. CONCLUSION Based on the results, smoking, alcohol, inactivity, high intake of sweets and desserts, low intake of fiber, depression, visceral fat, and obesity are considered as risk factors for GERD. Modifying lifestyle and behavioral habits prevent GERD.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a common condition, resulting from the loss of the anti-reflux barrier. Laparoscopic fundoplication is the surgical procedure of choice for treatment of GERD; however, there remains a debate on the exact mechanism through which it prevents reflux. OBJECTIVES Our aim was to understand the relationship between reflux, fundoplication, and the angle of His on an experimental model. METHODS The study was conducted on four groups of fresh explanted swine stomachs: control group, myotomy, myotomy with Nissen fundoplication, and myotomy with Toupet fundoplication. The stomachs were placed in a specially designated container on an inclinable platform which would increase the hydrostatic pressure on the esophago-gastric junction. Measurements of the angle of His using fluoroscopy and the esophago-gastric orifice area using endoscopy were performed, and the occurrence of reflux was documented. RESULTS Each group of the study contained nine swine stomachs. In the control and myotomy groups, the angle became wider as the incline level increased the pressure and was significantly different between the groups (p < .001). Both groups demonstrated an increase in the orifice area as the incline level increased the pressure. There was a significant correlation between the angle of His and the area of the esophago-gastric orifice (p < .001). In the control group, the reflux began at the 0°. In the myotomy group, it began at the + 15° incline (less pressure). Reflux rarely occurred in the Nissen and Toupet groups, with the breaking point being mostly defined as "beyond - 30°". A significant difference was noted in the occurrence of reflux between fundoplication and the non-fundoplication groups (p < 0.001), while there was no significant difference between the Toupet and Nissen groups (p = 0.134). Analysis showed a significant independent correlation between both the angle of His and the orifice area with the presence of reflux (p = .002 and p = .024 respectively). CONCLUSIONS In this study, we developed an experimental model to enable careful evaluation of the elements of the anti-reflux mechanism, of which, the angle of His has a measurable element. We demonstrated that as the angle of His becomes wider the esophago-gastric orifice area becomes larger. Additionally, a wider angle of His and a larger esophago-gastric orifice area were correlated independently with more reflux. This suggests that the fundoplication creates an acute angle of His which is correlated with a smaller area of the esophago-gastric orifice and eventually with a lower incidence of reflux.

Abstract
BACKGROUND Esophageal replacement (ER) with gastric pull-up (GPU) or jejunal interposition (JI) used to be the standard treatment for long-gap esophageal atresia (LGEA). Changes of the ER grafts on a macro- and microscopic level however, are unknown. AIM To evaluate long-term clinical symptoms and anatomical and mucosal changes in adolescents and adults after ER for LGEA. METHODS A cohort study was conducted including all LGEA patients ≥ 16 years who had undergone GPU or JI between 1985-2003 at two tertiary referral centers in the Netherlands. Patients underwent clinical assessment, contrast study and endoscopy with biopsy. Data was collected prospectively. Group differences between JI and GPU patients, and associations between different outcome measures were assessed using the Fisher's exact test for bivariate variables and the Mann-Whitney U-test for continuous variables. Differences with a P-value < 0.05 were considered statistically significant. RESULTS Nine GPU patients and eleven JI patients were included. Median age at follow-up was 21.5 years and 24.4 years, respectively. Reflux was reported in six GPU patients (67%) vs four JI patients (36%) (P = 0.37). Dysphagia symptoms were reported in 64% of JI patients, compared to 22% of GPU patients (P = 0.09). Contrast studies showed dilatation of the jejunal graft in six patients (55%) and graft lengthening in four of these six patients. Endoscopy revealed columnar-lined esophagus in three GPU patients (33%) and intestinal metaplasia was histologically confirmed in two patients (22%). No association was found between reflux symptoms and macroscopic anomalies or intestinal metaplasia. Three GPU patients (33%) experienced severe feeding problems vs none in the JI group. The median body mass index of JI patients was 20.9 kg/m2 vs 19.5 kg/m2 in GPU patients (P = 0.08). CONCLUSION The majority of GPU patients had reflux and intestinal metaplasia in 22%. The majority of JI patients had dysphagia and a dilated graft. Follow-up after ER for LGEA is essential.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is one of the complications of bariatric operations that might affect the quality of life. We aim to perform a retrospective cohort study to determine the incidence of symptomatic GERD following different types of bariatric surgery and which operations are considered a contraindication of GERD. Besides, we are attempting to identify the risk factors of GERD after bariatric surgery. METHODS Medical records of 729 patients who had undergone bariatric operations between January 2010 and June 2019 at the Shamir (Assaf Harofeh) Medical Center were reviewed. RESULTS There was a significant difference between the type of bariatric procedure and the incidence of GERD symptoms after the operation. The incidence of symptomatic GERD in patients who underwent sleeve gastrectomy (SG) was 39.9% (p = 0.0131). This was significantly higher compared to 16.4% following Roux-en-Y gastric bypass, 23.4% following laparoscopic adjustable gastric band, and 11% following one anastomosis gastric bypass. 113 patients out of 718 had a positive swallow test, and of these patients, 71 developed GERD symptoms postoperatively without correlation to the degree of reflux at the swallow test but with statistically significant correlation to the type of operation especially for SG (p value < 0.001), and to our knowledge, this was never reported in the literature. CONCLUSION SG is a good bariatric procedure option but should be considered carefully in asymptomatic patients with reflux at contrast swallow study and symptomatic GERD patients preoperatively because of high levels of symptomatic GERD postoperatively. Asymptomatic reflux at contrast swallow study preoperatively could be considered a risk factor for GERD after the operation. More studies are needed to be performed on this subject with the addition of postoperative contrast swallow test and pH monitoring preoperatively and postoperatively.

Abstract
Chest pain is a common presenting complaint in the primary care setting. Imaging plays a key role in the evaluation of the multiple organ systems that can be responsible for chest pain. With numerous imaging modalities available, determination of the most appropriate test and interpretation of the findings can be a challenge for the clinician. In this 2-part series, we offer resources to guide primary care physicians in the selection of imaging studies and present the imaging findings of various causes of nonemergent chest pain. In Part 2, we focus on the radiologic appearance of common noncardiac sources of chest pain, including gastrointestinal, pulmonary, and musculoskeletal etiologies.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a common and progressive disease characterised by chronic cough, airflow limitation and recurrent exacerbations. Since COPD exacerbations are linked to rising mortality and reduced quality of life, the condition poses a substantial burden on individuals, society and the healthcare system. Effective management of COPD exacerbations that includes treatment of related conditions in people with COPD is thus recognised as a relevant clinical question and an important research topic. Gastroesophageal reflux disease (GERD) is a known comorbidity of COPD, and pulmonary microaspiration of gastric acid is thought to be a possible cause of COPD exacerbations. Therefore, reducing gastric acid secretion may lead to a reduction in COPD exacerbations. Proton pump inhibitors (PPIs) are one of the most commonly prescribed medications and are recommended as first-line therapy for people with GERD because of their inhibitory effects on gastric acid secretion. Treatment with PPIs may present a viable treatment option for people with COPD. OBJECTIVES To evaluate the efficacy and safety of PPI administration for people with COPD, focusing on COPD-specific outcomes. SEARCH METHODS We searched the Cochrane Airways Register of Trials and conventional clinical trial registers from inception to 22 May 2020. We also screened bibliographies of relevant studies. SELECTION CRITERIA Parallel-group and cluster-randomised controlled trials (RCTs) that compared oral PPIs versus placebo, usual care or low-dose PPIs in adults with COPD were eligible for inclusion. We excluded cross-over RCTs, as well as studies with a duration of less than two months. DATA COLLECTION AND ANALYSIS Two independent review authors screened search results, selected studies for inclusion, extracted study characteristics and outcome data, and assessed risk of bias according to standard Cochrane methodology. We resolved discrepancies by involving a third review author. Primary outcomes of interest were COPD exacerbations, pneumonia and other serious adverse events. Secondary outcomes were quality of life, lung function test indices, acute respiratory infections and disease-specific adverse events. We extracted data on these outcome measures and entered into them into Review Manager software for analysis. MAIN RESULTS The search identified 99 records, and we included one multicentre RCT that randomised 103 adults with COPD. The 12-month RCT compared an oral PPI (lansoprazole) and usual care versus usual care alone. It was conducted at one tertiary care hospital and three secondary care hospitals in Japan. This study recruited participants with a mean age of 75 years, and excluded people with symptoms or history of GERD. No placebo was used in the usual care arm. Among the primary and secondary outcomes of this review, the study only reported data on COPD exacerbations and acute respiratory infections (the common cold). As we only included one study, we could not conduct a meta-analysis. The included study reported that 12 of the 50 people on lansoprazole had at least one exacerbation over a year, compared to 26 out of 50 on usual care (risk ratio 0.46, 95% CI 0.26 to 0.81). The frequency of COPD exacerbations per person in a year was also lower in the PPI plus usual care group than in the usual care alone group(0.34 ± 0.72 vs 1.18 ± 1.40; P < 0.001). The number of people with at least one cold over the year was similar in both groups: 26 people on lansoprazole and 27 people in the usual care group. We judged the evidence to be of low to very low certainty, according to GRADE criteria. The study reported no data on pneumonia and other serious adverse events, quality of life, lung function test indices or disease-specific adverse events. The risk of bias was largely low or unclear for the majority of domains, though the performance bias was a high risk, as the study was not blinded. AUTHORS' CONCLUSIONS Evidence identified by this review is insufficient to determine whether treatment with PPIs is a potential option for COPD. The sample size of the included trial is small, and the evidence is low to very low-certainty. The efficacy and safety profile of PPIs for people with COPD remains uncertain. Future large-scale, high-quality studies are warranted, which investigate major clinical outcomes such as COPD exacerbation rate, serious adverse events and quality of life.

Abstract
Although gastro-oesophageal reflux disease (GORD) is a common medical complaint, there is currently no consensus on the global prevalence of GORD. The aim of this study was to conduct a systematic review and meta-analysis on GORD prevalence and risk factors at a global level. MEDLINE, EMBASE, CINAHL, Scopus, Cochrane library, and Google Scholar were systematically searched, without language restrictions, for studies on the prevalence and risk factors of GORD. Data were pooled using a random effects model (95% confidence interval), and the odds ratio and relative risk for each risk factor were calculated. Out of 34,355 search results, 96 records reporting the results from 102 studies fulfilled the inclusion criteria, representing 37 countries and all regions of the UN geoscheme. The global pooled prevalence of GORD was 13.98% and varied greatly according to region (12.88% in Latin America and the Caribbean to 19.55% in North America) and country (4.16% in China to 22.40% in Turkey). Using the United Nations 2017 Revision of World Population Prospects, the estimated number of individuals suffering from GORD globally is 1.03 billion. Multiple risk factors associated with a significant increase in the risk of GORD were also identified. This systematic review and meta-analysis revealed that although a substantial proportion (13.98%) of the global population suffers from GORD, there are significant variations between regions and countries. Risk factors for GORD were also identified which may allow clinicians to recognise individuals most at risk.

Abstract
BACKGROUND/AIMS Ineffective esophageal motility (IEM) is the most common gastrointestinal motility disorder. Studies have reported that IEM is related to gastroesophageal reflux disease (GERD). However, the relationship between IEM and GERD remains uncertain. This study aims to clarify this relationship retrospectively. METHODS We analyzed 195 subjects who underwent high-resolution manometry between January 2011 and September 2016. Of these subjects, 72 had normal esophageal motility (NEM) and 26 had IEM. We investigated differences in the clinical characteristics, severity and duration of GERD symptoms, and comorbid extra-esophageal symptoms of the subjects. Comorbid extra-esophageal symptoms were assessed with the Gastrointestinal Symptom Rating Scale questionnaire. Investigation-defined GERD was diagnosed when erosive esophagitis or abnormal multichannel intraluminal impedance was present. RESULTS We found no significant difference in the prevalence of IEM between patients with and without GERD (37.5 and 21.1%, respectively; p = 0.174). There were no differences in age, gender, body mass index, presence of hiatal hernia, or duration of GERD between the groups. Compared to patients with NEM, those with IEM were significantly less likely to have comorbid extra-esophageal symptoms (p < 0.05). CONCLUSION There is no association between IEM and GERD.

Woodley FW, Moore-Clingenpeel M, Machado RS, Nemastil CJ, Jadcherla SR, Hayes D, Kopp BT, Kaul A, Di Lorenzo C, Mousa H. Not All Children with Cystic Fibrosis Have Abnormal Esophageal Neutralization during Chemical Clearance of Acid Reflux. Pediatr Gastroenterol Hepatol Nutr 2017; 20:153-159. [PMID: 29026731 PMCID: PMC5636931 DOI: 10.5223/pghn.2017.20.3.153] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/12/2017] [Revised: 07/12/2017] [Accepted: 07/15/2017] [Indexed: 01/25/2023] Open
Abstract
PURPOSE Acid neutralization during chemical clearance is significantly prolonged in children with cystic fibrosis, compared to symptomatic children without cystic fibrosis. The absence of available reference values impeded identification of abnormal findings within individual patients with and without cystic fibrosis. The present study aimed to test the hypothesis that significantly more children with cystic fibrosis have acid neutralization durations during chemical clearance that fall outside the physiological range. METHODS Published reference value for acid neutralization duration during chemical clearance (determined using combined impedance/pH monitoring) was used to assess esophageal acid neutralization efficiency during chemical clearance in 16 children with cystic fibrosis (3 to <18 years) and 16 age-matched children without cystic fibrosis. RESULTS Duration of acid neutralization during chemical clearance exceeded the upper end of the physiological range in 9 of 16 (56.3%) children with and in 3 of 16 (18.8%) children without cystic fibrosis (p=0.0412). The likelihood ratio for duration indicated that children with cystic fibrosis are 2.1-times more likely to have abnormal acid neutralization during chemical clearance, and children with abnormal acid neutralization during chemical clearance are 1.5-times more likely to have cystic fibrosis. CONCLUSION Significantly more (but not all) children with cystic fibrosis have abnormally prolonged esophageal clearance of acid. Children with cystic fibrosis are more likely to have abnormal acid neutralization during chemical clearance. Additional studies involving larger sample sizes are needed to address the importance of genotype, esophageal motility, composition and volume of saliva, and gastric acidity on acid neutralization efficiency in cystic fibrosis children.

Abstract
Differences in the aetiology as well as patient background of chronic cough have been recognised among US, UK, and Japan. One of the marked differences has been the prevalence of gastro-oesophageal reflux disease (GORD), which has been one of the top three causes in Western countries. It was indeed uncommon or rare in Japan, but, with the increasing prevalence of GOR itself, chronic cough associated with GORD seems to have become more common. In this article, cough associated with GORD will be reviewed based on literature and our Japanese experience. Further, potentially broader relevance of GORD in chronic cough will also be mentioned, highlighting the potential importance of dysmotiliy/non-acid reflux.

Abstract
Objective The risk factors associated with severe erosive esophagitis are not well defined in Japan. We aimed to evaluate the risk factors associated with the endoscopic severity of esophageal mucosal injury. Methods Eighty consecutive Japanese patients with severe erosive esophagitis [Los Angeles (LA) classification grade C or D] who had undergone upper endoscopies in the Gastroenterology Division of Omori Red Cross Hospital between June 2010 and March 2013 were retrospectively analyzed. For each case, a control with mild erosive esophagitis (LA classification grade A or B) who was matched by sex and age was randomly selected during the same period. Among the endoscopic findings, the condition of the gastroesophageal flap valve (GEFV) was graded according to Hill's classification. We identified the risk factors for severe erosive esophagitis using a multivariable logistic regression model. Results A poor performance status (PS) (odds ratio [OR]=17.1201, 95% confidence interval [CI]=3.0268-140.3121, p=0.0008) and an abnormal GEFV (OR=3.0176, 95% CI=1.0589-9.4939, p=0.0385) were risk factors for severe erosive esophagitis, while the presence of open-type gastric mucosal atrophy (GMA) was inversely associated with severe erosive esophagitis (OR=0.2772, 95% CI=0.1087-0.6675, p=0.0040). Conclusion Among patients with erosive esophagitis, a poor PS and an abnormal GEFV were associated while GMA was inversely associated with severe erosive esophagitis. Drug therapy alone or in combination with physical therapy may improve the therapeutic effect on severe erosive esophagitis in patients with a poor PS.

Greater curvature myotomy is a safe and effective modified technique in per-oral endoscopic myotomy (with videos). Gastrointest Endosc 2016; 81:1370-7. [PMID: 25686872 DOI: 10.1016/j.gie.2014.11.014] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2014] [Accepted: 11/05/2014] [Indexed: 02/06/2023]
Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM) for achalasia with esophagocardiomyotomy in the lesser curvature (LC myotomy) is now established and accepted widely. However, in some cases LC myotomy is precluded by previous procedures, such as Heller myotomy, or by other anatomic considerations that obscure the normal dissection planes. It may also be difficult to identify the esophagogastric junction (EGJ), which can result in an incomplete gastric myotomy and poor rates of symptom relief. On the other hand, the angle of His is always located in the greater curvature of the stomach and serves as a consistent, definite landmark of the gastric side. OBJECTIVE To evaluate esophagocardiomyotomy in the greater curvature (GC myotomy) as an alternative POEM technique in cases where a prior LC myotomy or supervening anatomic constraints make identification of the EGJ technically challenging. DESIGN Prospective. SETTING Single-center study. PATIENTS Twenty-one achalasia patients who received POEM with GC myotomy. INTERVENTIONS POEM. MAIN OUTCOME MEASUREMENTS Efficacy and safety of GC myotomy measured in terms of reduction in lower esophageal sphincter (LES) pressures, improvement in Eckardt scores, and development of intraoperative or postoperative adverse events. RESULTS Identification of the EGJ was achieved in all cases, resulting in a mean gastric myotomy length of 2.6±1.1 cm. Mean LES pressure and Eckardt symptom scores decreased significantly (21.2±7.3 vs 10.5±2.7 mm Hg, 5 [2-8] vs 1 [0-5], respectively) (P<.01). Endoscopic evidence of gastroesophageal reflux was identified in 52% of patients (11/21) postmyotomy; however, only 9.5% (2/11) were symptomatic, and these patients were successfully controlled with proton pump inhibitors. No severe adverse events were encountered. LIMITATIONS Single center. CONCLUSIONS GC myotomy is a promising, safe modification of the POEM technique and may be especially useful in cases of redo POEM, POEM post-Heller myotomy, or when the EGJ is difficult to recognize because of supervening anatomic constraints.

Abstract
BACKGROUND Multiple rapid swallowing (MRS) during high-resolution manometry (HRM) is increasingly utilized as provocative test to assess esophageal peristaltic reserve. The aim of this study was to evaluate the correlation between MRS response and impedance and pH (MII-pH) parameters in endoscopy negative heartburn (ENH) patients. METHODS We enrolled consecutive ENH patients, who underwent HRM and MII-pH study, with a selected MII-pH profile: abnormal MII-pH (pH+/MII+); normal MII-pH (pH-/MII-). HRM was performed with 10 wet swallows (WS) and one MRS. Mean distal contractile integral (DCI) during WS and MRS were calculated. MII-pH parameters including acid exposure time (AET), reflux events, baseline impedance levels (BI) and the efficacy of chemical clearance evaluated with the postreflux swallow-induced peristaltic wave (PSPW) index were measured. KEY RESULTS We analyzed 103 patients: 49 MII+/pH+ (27 male), and 54 MII-/pH- (19 male). Mean age was similar between the two groups. As expected, mean AET and number of refluxes were higher in pH+/MII+ (p < 0.05). HRM was normal in all selected patients. Mean DCI-WS was similar between two groups (p = n.s.). Mean DCI-MRS- was higher in MII-/pH- vs MII+/pH+ (p < 0.05). The increase in DCI-MRS was inversely correlated with AET (-0.699; p < 0.001) and directly correlated with BI values (0.631; p < 0.001) and PSPW index (0.626; p < 0.001). CONCLUSIONS & INFERENCES Following MRS, patients with abnormal impedance-pH test showed suboptimal contraction response as compared with those with normal impedance-pH test. Moreover, MRS response was inversely correlated with AET and directly correlated with BI values and PSPW index.

Abstract
Objectives. Baclofen can relieve gastroesophageal reflux-related symptoms in healthy subjects and gastroesophageal reflux disease (GERD) patients by reducing the incidence of transient lower esophageal sphincter relaxation. This meta-analysis aimed to evaluate the efficacy and safety of baclofen for the treatment of GERD. Methods. We systematically searched randomized controlled trials published prior to November 2013 from PubMed, Medline, Embase, ScienceDirect, ClinicalTrials.gov, and the Cochrane Central Register of Randomized Controlled Trials. We performed a meta-analysis of all eligible trials. Results. Nine studies were identified with a total of 283 GERD patients and healthy subjects. Comparative analysis provided high quality data supporting the ability of baclofen to promote a short-term decrease in the number of reflux episodes per patient, the average length of reflux episodes, and the incidence of transient lower esophageal sphincter relaxation. No serious adverse events or death events were reported, and there were no significant differences in the overall adverse events between baclofen and placebo. All reported side effects of baclofen were of mild-to-moderate intensity, and the drug was well tolerated. Conclusion. Abundant evidence suggests that baclofen may be a useful approach for the treatment of GERD patients; however, a larger well-designed research study would further confirm this recommendation.

Abstract
BACKGROUND Obesity has been reported to adversely affect the outcome of laparoscopic antireflux surgery (LARS). This study examined pre- and postoperative clinical and objective outcomes and quality of life in obese and normal-weight patients following LARS at a specialized centre. METHODS Prospective data from patients subjected to LARS (Nissen or Toupet fundoplication) for symptomatic gastroesophageal reflux disease in the General Public Hospital of Zell am See were analyzed. Patients were divided in two groups: normal weight [body mass index (BMI) 20-25 kg/m(2)] and obese (BMI ≥ 30 kg/m(2)). Gastrointestinal quality of life index (GIQLI), symptom grading, esophageal manometry and multichannel intraluminal impedance monitoring data were documented and compared preoperatively and at 1 year postoperatively. RESULT The study cohort included forty normal-weight and forty obese patients. Mean follow-up was 14.7 ± 2.4 months. The mean GIQLI improved significantly after surgery in both groups (p < 0.001, for both). Clinical outcomes improved following surgery regardless of BMI. There were significant improvements of typical and atypical reflux symptoms in normal weight and obese (p = 0.007; p = 0.006, respectively), but no difference in gas bloat and bowel dysfunction symptoms could be found. No intra- or perioperative complications occurred. A total of six patients had to be reoperated (7.5 %), two (5 %) in the obese group and four (10 %) in the normal-weight group, because of recurrent hiatal hernia and slipping of the wrap or persistent dysphagia due to closure of the wrap. CONCLUSION Obesity is not associated with a poorer clinical and objective outcome after LARS. Increased BMI seems not to be a risk factor for recurrent symptomatology and reoperation.

Abstract
BACKGROUND Gastroesophageal flap valve (GEFV) endoscopic grading is reported to be associated with gastroesophageal reflux disease (GERD) in adults; however its role in pediatric groups remains unknown. This study aimed to investigate the significance of GEFV grading and the associations to multichannel intraluminal impedance and pH monitoring (MII-pH) in children with GERD. METHODS A total of 48 children with GERD symptoms who received esophagogastroduodenoscopy and MII-pH monitoring were enrolled. The degree of GEFV was graded from I to IV according to the Hill classification, and classified into two groups: normal GEFV (Hill grades I and II), and abnormal GEFV (Hill grades III and VI). Endoscopic findings and MII-pH monitoring were analyzed among the groups. RESULTS Thirty-six patients had normal GEFV while 12 had abnormal GEFV. The presence of erosive esophagitis was significantly more common in the patients with abnormal GEFV (p = 0.037, OR 9.84, 95% CI 1.15-84.42). Pathological acidic gastroesophageal reflux (GER) determined by MII-pH was more prevalent in the patients with loosened GEFV geometry (p = 0.01, OR 7.0, 95% CI 1.67-27.38). There were significant positive correlations between GEFV Hill grading I to IV and the severity of erosive esophagitis (r = 0.49, p<0.001), percentage of supine acid reflux (r = 0.37, p = 0.009), percentage of total acid reflux (r = 0.3284, p = 0.023), and DeMeester score (r = 0.36, p = 0.01) detected by pH monitoring. In the impedance study, GEFV Hill grading also positively correlated to median number of acid reflux events (r = 0.3015, p = 0.037). CONCLUSIONS GEFV dysfunction highly associated with acid GER and severe erosive esophagitis. An abnormal GEFV is a sign of acid GER in children.

Abstract
PURPOSE OF REVIEW In the last decade, with the advent of new oesophageal testing [i.e. 24-h impedance-pH monitoring, combined impedance-manometry, high-resolution manometry (HRM)], relevant progress in understanding the mechanisms contributing to the development of gastro-oesophageal reflux disease (GORD) has been made, allowing a better management of patients with this disorder. The aim of our review is to report the state-of-the-art about oesophageal motor disorders in patients with reflux disease and to stimulate new research in this field. RECENT FINDINGS Hypotensive lower oesophageal sphincter (LOS), transient LOS relaxations, impairment of oesophagogastric junction including hiatal hernia, oesophageal bolus transit abnormalities and presence of ineffective oesophageal motility have been strongly implicated in GORD development. In particular, the majority of recent studies carried out with HRM and impedance-pH testing reported that these motor abnormalities are increasingly prevalent with increasing severity of GORD, from nonerosive reflux disease and erosive oesophagitis to Barrett's oesophagus. SUMMARY Defining and characterizing oesophageal dysmotility in patients with reflux disease is of maximum importance in order to properly diagnose these patients and to treat them with the best management of care. New studies are needed in order to better understand the physiomechanic basis of oesophageal dysmotility in GORD patients.

Abstract
Obesity is an epidemic that is known to play a role in the development of gastroesophageal reflux disease (GERD). Studies have shown that increasing body mass index plays a role in the incompetence of the gastroesophageal junction and that weight loss and lifestyle modifications reduce the symptoms of GERD. As a method of producing effective and sustainable weight loss, bariatric surgery plays a major role in the treatment of obesity. We reviewed the literature on the effects of different types of bariatric surgery on the symptomatic relief of GERD and its complications. Roux-en- Y gastric bypass was considered an effective method to alleviate symptoms of GERD, whereas laparoscopic sleeve gastrectomy appeared to increase the incidence of the disease. Adjustable gastric banding was seen to initially improve the symptoms of GERD; however, a subset of patients experienced a new onset of GERD symptoms during long-term follow-up. The literature suggests that different surgeries have different impacts on the symptomatology of GERD and that careful assessment may be needed before performing bariatric surgery in patients with GERD.

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 Many reconstructive procedures have been developed in an effort to resolve complications after total gastrectomy (TG). However, anatomical disruption of the esophagogastric junction, especially the low esophageal sphincter, still occurs so that postoperative complications continue to arise. In this study, we developed a procedure for intracorporeal laparoscopic Roux-en-Y gastrojejunostomy (RYGJ) after 95% (near-total) gastrectomy, to reduce postoperative complications in early gastric cancer (EGC) of the upper third of the stomach. PATIENTS AND METHODS Laparoscopic RYGJ after 95% gastrectomy was performed on 21 patients with EGC in the upper third of the stomach between May 2011 and April 2012 in Asan Medical Center, Seoul, Korea. The resection line of the stomach was marked using metallic preoperative endoscopic clips and intraoperative laparascopic vessel clips together with a portable abdominal radiograph. Approximately 95% of the stomach was transected using an endoscopic linear stapler, and an antecolic side-to-side gastrojejunal anastomosis was created between the posterior side of the gastric remnant and the antimesenteric side of the jejunal limb, also using an endoscopic linear stapler. The entry hole was first closed in approximate fashion with three sutures, and closure was completed with an endoscopic linear stapler. RESULTS Intracorporeal laparoscopic RYGJ after 95% gastrectomy was successfully performed in all patients. No patients required conversion to open surgery or other laparoscopic anastomosis techniques. No postoperative complications occurred. All patients had tumor-free resection margins, and there was no mortality. CONCLUSIONS Intracorporeal laparoscopic RYGJ after 95% gastrectomy can be performed easily and safely. We recommend this method over laparoscopic TG or open TG for treatment of EGC in the upper third of the stomach.

Abstract
BACKGROUND Achalasia is characterized by esophageal aperistalsis and impaired relaxation of the lower esophageal sphincter (LES). This contrasts with an insufficient LES, predisposing to gastro-esophageal reflux and Barrett's esophagus. The co-incidence of achalasia and BE is rare. Pneumatic dilatation (PD) may lead to gastro-esophageal reflux, Barrett's esophagus development, and esophageal adenocarcinoma. AIMS To determine the incidence of Barrett's esophagus and esophageal adenocarcinoma in achalasia patients treated with PD. METHODS We performed a single-center cohort follow-up study of 331 achalasia patients treated with PD. Mean follow-up was 8.9 years, consisting of regular esophageal manometry, timed barium esophagram, and endoscopy. RESULTS Twenty-eight (8.4%) patients were diagnosed with Barrett's esophagus, one at baseline endoscopy. This corresponds with an annual incidence of Barrett's esophagus of 1.00% (95% CI 0.62-1.37). Hiatal herniation was present in 74 patients and 21 developed Barrett's esophagus compared to seven of 257 patients without a hiatal hernia. Statistical analysis revealed a hazard ratio of 8.04 to develop Barrett's esophagus if a hiatal hernia was present. Post-treatment LES pressures were lower in patients with Barrett's esophagus than in those without (13.9 vs. 17.4 mmHg; p = 0.03). Two (0.6%) patients developed esophageal adenocarcinoma during follow-up. CONCLUSIONS Barrett's esophagus is incidentally diagnosed in untreated achalasia patients despite high LES pressures, but is more common after successful treatment, especially in the presence of hiatal herniation. Patients treated for achalasia should be considered for GERD treatment and surveillance of development of Barrett's esophagus, in particular, when they have low LES pressures and a hiatal herniation.

Abstract
BACKGROUND Previous studies suggest an association between obesity and oesophageal (OA) and oesophagogastric junction adenocarcinomas (OGJA). However, these studies have been limited in their ability to assess whether the effects of obesity vary by gender or by the presence of gastro-oesophageal reflux (GERD) symptoms. METHODS Individual participant data from 12 epidemiological studies (8 North American, 3 European and 1 Australian) comprising 1997 OA cases, 1900 OGJA cases and 11 159 control subjects were pooled. Logistic regression was used to estimate study-specific odds ratios (ORs) and 95% confidence intervals (CIs) for the association between body mass index (BMI, kg/m(2)) and the risk of OA and OGJA. Random-effects meta-analysis was used to combine these ORs. We also investigated effect modification and synergistic interaction of BMI with GERD symptoms and gender. RESULTS The association of OA and OGJA increased directly with increasing BMI (P for trend <0.001). Compared with individuals with a BMI <25, BMI ≥40 was associated with both OA (OR 4.76, 95% CI 2.96-7.66) and OGJA (OR 3.07, 95% CI 1.89-4.99). These associations were similar when stratified by gender and GERD symptoms. There was evidence for synergistic interaction between BMI and GERD symptoms in relation to OA/OGJA risk. CONCLUSIONS These data indicate that BMI is directly associated with OA and OGJA risk in both men and women and in those with and without GERD symptoms. Disentangling the relationship between BMI and GERD will be important for understanding preventive efforts for OA and OGJA.

Abstract
AIM: To investigate the symptom presentation and quality of life in obese Chinese patients with gastroesophageal reflux disease (GERD).
METHODS: Data from patients diagnosed with GERD according to the Montreal definition, were collected between January 2009 to March 2010. The enrolled patients were assigned to the normal [body mass index (BMI) < 25 kg/m2], overweight (25-30 kg/m2), and obese (BMI > 30 kg/m2) groups. General demographic data, endoscopic findings, and quality of life of the three groups of patients were analyzed and compared.
RESULTS: Among the 173 enrolled patients, 102, 56 and 15 patients were classified in the normal, overweight, and obese, respectively. There was significantly more erosive esophagitis (73.3% vs 64.3% vs 39.2%, P = 0.002), hiatal hernia (60% vs 33.9% vs 16.7%, P = 0.001), and males (73.3% vs 73.2% vs 32.4%, P = 0.001) in the obese cases. The severity and frequency of heartburn, not acid regurgitation, was positively correlated with BMI, with a significant association in men, but not in women. Obese patients were prone to have low quality of life scores, with obese women having the lowest scores for mental health.
CONCLUSION: In patients with GERD, obese men had the most severe endoscopic and clinical presentation. Obese women had the poorest mental health.

Abstract
Gastroesophageal reflux (GER) is a common presenting complaint in children and adults, and is a frequent reason for physician consultation. GER disease (GERD), whilst benign in the majority of cases, is frequently a chronic condition that has been shown to result in significantly reduced quality of life in children and adolescents. Furthermore, there is emerging evidence that the prevalence of GERD is rising and may have links to adult obesity and other morbidities. Consequently, accurate diagnosis, appropriate management strategies, and timely referral to specialist services are important principles in the effective management of GERD. Acid-suppressive drugs are effective therapies but are one of the most costly classes of drugs prescribed. Therefore, not only is an accurate diagnosis important to the patient, but it is also of significant interest from a public health and resource utilization standpoint.

Abstract
BACKGROUND Limited data are available regarding the frequency of oesophageal motility and bolus transit abnormalities in subgroups of patients with gastro-oesophageal reflux disease (GERD). AIM To assess oesophageal motility and bolus transit in endoscopically defined GERD subgroups. METHODS Patients (N=755) with typical reflux symptoms underwent upper endoscopy, conventional or impedance oesophageal manometry and/or impedance-pH testing. They were divided into: erosive oesophagitis (EO; N=340), Barrett Oesophagus (BO; N=106), non-erosive reflux disease (NERD; endoscopy-, abnormal pH and/or SAP/SI+; N=239) and functional heartburn (FH; endoscopy-, normal pH and SAP/SI-; N=70). Manometric patterns and bolus transit were defined according to previously published criteria. RESULTS Increasing GERD severity was associated with decreased lower oesophageal sphincter resting pressure (P< 0.05) and distal oesophageal amplitude (P<0.01), higher prevalence of hiatal hernia (P<0.01) and increased prevalence of ineffective oesophageal motility (P<0.01). Patients with EO and BO had a significantly lower percentage of complete bolus transit compared with NERD and FH (P<0.01). Overall, abnormal bolus transit (ABT) for liquid swallows was found in 12% of FH, 20% of NERD, 54% of EO and 56% of BO (P<0.01). Combined impedance-manometry showed abnormal oesophageal function in 4% of FH, 4% of NERD, 22% of EO and 21% of BO patients with normal oesophageal manometry. CONCLUSIONS Oesophageal motility abnormalities increase in parallel with the severity of GERD from NERD to EO and BO. Bolus transit abnormalities in severe reflux disease underscore the importance of impaired oesophageal function in the development of mucosal injury.

Abstract
BACKGROUND Obesity is recently known as a risk factor for endoscopic gastritis. Adiponectin is an anti-inflammatory cytokine secreted from fat tissue, and its serum concentrations are reduced in obesity. The relation between adiponectin and gastritis remains unclear. AIMS The aim of this study was to determine whether lower serum adiponectin level is associated with the risk of endoscopic gastritis. METHODS We analyzed medical records of participants of a routine health check-up examination. Association among endoscopic findings, serum adiponectin level, and other clinical factors including age, sex, alcohol habit, smoking habit, body mass index (BMI), blood pressure, cholesterol, triglyceride, glucose, and insulin were investigated. Endoscopic erosive gastritis was defined as a flat or minimally depressed white spot surrounded by a reddish area or small elevation with central umbilications mimicking octopus' suckers. RESULTS A total of 2,400 participants were enrolled. BMI was significantly higher in gastritis-positive participants than in gastritis-negative participants. Serum adiponectin levels were significantly lower in gastritis-positive participants than in gastritis-negative participants. Multivariate logistic regression analysis revealed that lower serum adiponectin level (OR 0.96; 95% CI 0.93-0.99), smoking (OR 0.50; 95% CI 0.30-0.80), higher blood pressure (OR 1.02; 95% CI 1.01-1.03), and duodenitis (OR 1.8; 95% CI 1.00-3.09) were significantly associated with endoscopic erosive gastritis. CONCLUSIONS Lower serum level of adiponectin may increase the risk of endoscopic erosive gastritis, independently of BMI. Our findings facilitate further study to clarify the role of hypoadiponectinemia in erosive gastritis.

Abstract
BACKGROUND Rates of distal and junctional adenocarcinomas are increasing in Western countries. METHODS Systematic review of epidemiological evidence linking obesity to esophageal adenocarcinoma (EA) was performed for studies published from 2005 to 2010. The current understanding of obesity's role in the etiology and potential dysplastic progression of Barrett's esophagus (BE) to EA is reviewed. RESULTS Accumulating epidemiological studies provide evidence of obesity's role as a driving force behind the increasing rates of EA. The simplest construct is that obesity promotes reflux, causing chronic inflammation and BE, predisposing to adenocarcinoma. However, as obesity is positively associated with the prevalence of many cancers, other mechanisms are important. A link may exist between fat distribution patterns and the risk of BE and EA. Altered metabolic profiles in the metabolic syndrome (MetS) may be a key factor in cell cycle/genetic abnormalities that mark the progression of BE towards cancer. Research highlighting a unique role of MetS in the length of BE, and its association with systemic inflammation and insulin resistance is discussed, as well as adipokine receptor expression in both BE and esophageal epithelium, and how MetS and the systemic response impacts on key regulators of inflammation and tumorigenesis. CONCLUSIONS/IMPACT: Obesity is positively associated with EA. The systemic inflammatory state consequent on the altered metabolism of obese patients, and the associated impact of adipocytokines and pro-coagulant factors released by adipocytes in central fat, may underlie obesity's relationship to this cancer. Novel therapeutic agents that may antagonize adipo-cytokines and potentially offer a promising role in cancer therapy are discussed.

Abstract
Gastroesophageal reflux disease (GERD), previously uncommon in Asia, has now become an important disease in the region. Although much variability exists between studies, most endoscopy-based studies show a prevalence of erosive esophagitis of more than 10%. Symptom-based studies also show a prevalence of 6-10%. Two longitudinal follow-up studies on GERD symptoms have shown an increase with time, and several endoscopy-based time trend studies have also shown a significant increase in erosive reflux esophagitis. Studies on Barrett's esophagus have been confounded by the description of short (SSBE) and long segment (LSBE) Barrett's esophagus. Great variation in prevalence rates has been reported. SSBE vary from 0.1% to more than 20% while LSBE vary from 1-2%. Of the putative causative factors, obesity has been the most important. Many studies have linked GERD-esophagitis as well as occurrence of reflux symptoms with an increase in body mass index (BMI), obesity, especially visceral or central obesity, and metabolic syndrome. A decline in Helicobacter pylori infection with growing affluence in Asia has been broadly thought to result in healthier stomachs and a higher gastric acid output resulting in reflux disease. However, variable results have been obtained from association and H. pylori eradication studies.

Abstract
Relief of adverse events induced by chemotherapy is an important issue for patients, especially those with a poor prognosis, such as with pancreatic cancer. There are no reports of the relationship between gastroesophageal reflux disease (GERD) and chemotherapy, so we investigated the incidence of chemotherapy-induced GERD in patients undergoing treatment with gemcitabine or S-1 for pancreatic cancer and the effect of sodium rabeprazole (RPZ), a proton-pump inhibitor. GERD was diagnosed in 40% of the patients according to the Frequency Scale for Symptoms of GERD score, and RBZ therapy significantly improved their symptoms.

Abstract
Gastroesophageal reflux disease (GERD) is caused by abnormal reflux of gastric contents into the esophagus. GERD can be divided into two groups, erosive esophagitis and non-erosive reflux disease (NERD). The aim of this study was to compare the clinical characteristics of patients with erosive esophagitis to those with NERD. All participating patients underwent an upper endoscopy during a voluntary health check-up. The NERD group consisted of 500 subjects with classic GERD symptoms in the absence of esophageal mucosal injury during upper endoscopy. The erosive esophagitis group consisted of 292 subjects with superficial esophageal erosions with or without typical symptoms of GERD. Among GERD patients, male gender, high body mass index, high obesity degree, high waist-to-hip ratio, high triglycerides, alcohol intake, smoking and the presence of a hiatal hernia were positively related to the development of erosive esophagitis compared to NERD. In multivariated analysis, male gender, waist-to-hip ratio and the presence of a hiatal hernia were the significant risk factors of erosive esophagitis. We suggest that erosive esophagitis was more closely related to abdominal obesity.

Abstract
BACKGROUND Obesity and overweight have been positively related to gastro-oesophageal reflux disease (GERD). It has been suggested that this relationship is as a consequence of an increased gastric acid reflux, which is caused by an enhanced intra-abdominal pressure. AIM To assess potential interaction of the association between body mass index (BMI) and GERD by chronic atrophic gastritis, which goes along with decreased acid production. METHODS In the baseline examination of ESTHER, a study conducted in 9953 older adults in Saarland, information on frequency of heartburn, potential risk factors and medical history was obtained by self-administered standardized questionnaire. Serological measurements of pepsinogen I and II were taken for definition of chronic atrophic gastritis. RESULTS In total, 2565 (28.7%) of the included subjects experienced heartburn within the previous 4 weeks. A pronounced dose-response relationship was observed between BMI and heartburn occurrence (P < 0.001) among people without chronic atrophic gastritis, but not among people with chronic atrophic gastritis (P-value for interaction = 0.018). Obese/overweight people with chronic atrophic gastritis had a much lower risk of heartburn compared with obese/overweight people without chronic atrophic gastritis (OR = 0.31, 95% CI = 0.24-0.40). CONCLUSION Our results are consistent with the hypothesis that BMI is related positively to GERD symptoms by its impact on acid reflux.

Abstract
OBJECTIVE The aim of the study was to compare the esophagogastric junction (EGJ) compliance in response to controlled distension in fundoplication (FP) patients and controls using the functional luminal imaging probe (FLIP). BACKGROUND FP aims to replicate normal EGJ distensibility. FLIP is a new technology that uses impedance planimetry to measure intraluminal cross-sectional area (CSA) during controlled distension. METHODS Ten controls and ten FP patients were studied with high-resolution esophageal pressure topography (HREPT) and then the FLIP placed across the EGJ. Deglutitive and interdeglutitive EGJ distensibility was assessed with volume-controlled distension. The FLIP measured eight CSAs spaced 4 mm apart within a cylindrical saline-filled bag along with the corresponding intrabag pressure. RESULTS The EGJ formed an hourglass shape during distensions with the central constriction at the diaphragmatic hiatus. The distensibility of the hiatus was significantly greater during deglutitive relaxation in both subject groups, but FP patients exhibited reduced EGJ distensibility and compliance compared to controls. During the interglutitive period, the corresponding increase in intrabag pressures at larger volumes were also greater in FP patients implying a longer segment of EGJ constriction. The EGJ distensibility characteristics did not correlate with HREPT measures. CONCLUSIONS FLIP technology was used to compare EGJ distensibility in FP patients and control subjects. The least distensible locus within the EGJ was always at the hiatus. EGJ distensibility was significantly reduced, and the length of constriction increased in FP patients. Future FLIP studies will compare patients with and without post-FP dysphagia and gas bloat, symptoms suggestive of an overly restrictive FP.

[PMID: 20069112 PMCID: PMC2804043 DOI: 10.1155/2009/371580] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2009] [Revised: 10/14/2009] [Accepted: 10/26/2009] [Indexed: 12/14/2022] Open
Abstract
Background. Gastroesophageal reflux disease is a common condition with increasing prevalence worldwide. The disease encompasses a broad spectrum of clinical symptoms and disorders from simple heartburn without esophagitis to erosive esophagitis with severe complications, such as esophageal strictures and intestinal metaplasia. Diagnosis is based mainly on ambulatory esophageal pH testing and endoscopy. There has been a long-standing debate about the best treatment approach for this troublesome disease. Methods and Results. Medical treatment with PPIs has an excellent efficacy in reversing the symptoms of GERD, but they should be taken for life, and long-term side effects do exist. However, patients who desire a permanent cure and have severe complications or cannot tolerate long-term treatment with PPIs are candidates for surgical treatment. Laparoscopic antireflux surgery achieves a significant symptom control, increased patient satisfaction, and complete withdrawal of antireflux medications, in the majority of patients. Conclusion. Surgical treatment should be reserved mainly for young patients seeking permanent results. However, the choice of the treatment schedule should be individualized for every patient. It is up to the patient, the physician and the surgeon to decide the best treatment option for individual cases.

Abstract
BACKGROUND AND AIM Our aim was to determine associations between metabolic risk factors and erosive esophagitis. METHODS In this retrospective case-control study, diagnosis of erosive esophagitis was based on the Los Angeles classification. Endoscopic findings in subjects with erosive esophagitis were reviewed by two experienced endoscopists and those with agreement of diagnosis were enrolled for study. Body mass index (BMI), abdominal girdle, blood pressure, and serum triglyceride, glucose, and beta-lipoprotein levels were compared between individuals with and without erosive esophagitis. Multivariate binary logistic regression analysis was used to identify independent metabolic risk factors associated with erosive esophagitis. RESULTS Between October 2004 and April 2006, 518 of 4206 subjects who underwent endoscopic examination were diagnosed as having erosive esophagitis. After expert review, 427 (male : female = 365:62) individuals met the study criteria of having erosive esophagitis (10.5%). Compared with age- and gender-matched controls, patients with erosive esophagitis had significantly higher BMI, abdominal girdle, blood pressure, and triglyceride levels, and lower levels of high density lipoprotein (HDL) cholesterol (P < 0.05). More subjects with metabolic syndrome had erosive esophagitis than without metabolic syndrome (OR: 1.76, 95% CI: 1.27-2.44, P = 0.001). Multivariate logistic regression analysis revealed that central obesity (OR: 1.41, 95% CI: 05-1.89, P = 0.023) and hypertriglyceridemia (OR: 1.57, 95% CI: 1.19-2.13, P = 0.004) were significantly associated with erosive esophagitis. CONCLUSIONS Obesity and hypertriglyceridemia, which are key components of metabolic syndrome, are moderate independent risk factors for erosive esophagitis.

Abstract
CONTEXTO: Existe uma noção geral de que indivíduos obesos desenvolvem mais freqüentemente a doença do refluxo gastroesofagiano, sendo a orientação de perder peso parte integrante do seu tratamento. Entretanto, uma base científica para esta associação não está plenamente estabelecida. OBJETIVOS: Avaliar a prevalência de obesidade e sobrepeso em pacientes com sintomas típicos de refluxo, com e sem esofagite erosiva. Analisar a prevalência de hérnia hiatal e a intensidade do refluxo anormal em relação ao índice de massa corporal nos dois grupos de pacientes. MÉTODOS: Foram examinadas retrospectivamente 362 pHmetrias de pacientes com pirose, todos com endoscopia digestiva alta prévia, definindo-se esofagite erosiva pela presença de erosões esofagianas macroscópicas e hérnia de hiato quando à junção esôfago-gástrica estava 2 cm ou mais acima do pinçamento diafragmático. Pacientes com esôfago de Barrett ou estenose péptica foram excluídos. A população foi dividida em três grupos de acordo com o índice de massa corpórea: peso normal, com índice de massa corporal entre 20 e 24,9, sobrepeso, com 25 e 29,9 e obesos com índice superior a 30. O diagnóstico de refluxo gastroesofagiano anormal com sua intensidade foi avaliado de acordo com os resultados de pHmetrias, analisados nos grupos de pacientes com e sem esofagite erosiva em relação ao índice de massa corporal. RESULTADOS: Entre os 362 pacientes, havia 148 (41%) com e 214 (59%) sem esofagite erosiva, sendo a pHmetria anormal em 100% e 57% dos pacientes, retrospectivamente. Entre os 148 (61% do sexo masculino, mediana de idade de 50 anos), 41 (28%) apresentavam peso normal, 82 (55%) sobrepeso e 25 (17%) eram obesos. Havia 88 (60%) com hérnia hiatal, sendo 29 (71% dos pacientes com peso normal), 45 (55% dos com sobrepeso) e 14 (56% dos obesos). Nos 121 indivíduos sem esofagite erosiva e com pHmetria anormal, diagnosticados como doentes com doença do refluxo não-erosiva (38% masculino, mediana de idade de 50 anos), havia 51 (42%) pacientes com peso normal, 55 (46%) com sobrepeso e 15 (12%) eram obesos. Detectou-se hérnia de hiato em 52 (43%) dos 121 pacientes, sendo 21 (41% dos indivíduos com peso normal), 24 (44% dos com sobrepeso) e 7 (47% dos obesos). Naqueles 93 pacientes sem esofagite erosiva e com pHmetria normal (39% homens, mediana de idade de 43 anos) havia 43 (46%) pacientes com peso normal, 38 (41%) com sobrepeso e 12 (13%) obesos, sendo 26 (28%) com hérnia hiatal. A prevalência de hérnia de hiato, assim como o número de pacientes com obesidade e sobrepeso foi significantemente maior no grupo de doença do refluxo erosiva, quando comparado ao grupo sem esofagite erosiva. A intensidade do refluxo, assim como a prevalência de hérnia hiatal foram similares nos pacientes com peso normal, sobrepeso e obesos, em ambos os grupos. CONCLUSÃO:A prevalência de obesidade e sobrepeso é maior em indivíduos com doença do refluxo erosiva do que naqueles sem esofagite erosiva. Não houve diferença na intensidade do refluxo entre as várias categorias de índice de massa corporal, em nenhum dos grupos estudados. Embora a hérnia hiatal seja mais prevalente na doença do refluxo erosiva, esta superioridade não se relacionou ao excesso de peso.

Abstract
AIM: To evaluate the association between ineffective esophageal motility (IEM) and gastropharyngeal reflux disease (GPRD) in patients who underwent ambulatory 24-h dual-probe pH monitoring for the evaluation of supraesophageal symptoms.
METHODS: A total of 632 patients who underwent endoscopy, esophageal manometry and ambulatory 24-h dual-pH monitoring due to supraesophageal symptoms (e.g. globus, hoarseness, or cough) were enrolled. Of them, we selected the patients who had normal esophageal motility and IEM. The endoscopy and ambulatory pH monitoring findings were compared between the two groups.
RESULTS: A total of 264 patients with normal esophageal motility and 195 patients with the diagnosis of IEM were included in this study. There was no difference in the frequency of reflux esophagitis and hiatal hernia between the two groups. All the variables showing gastroesophageal reflux and gastropharyngeal reflux were not different between the two groups. The frequency of GERD and GPRD, as defined by ambulatory pH monitoring, was not different between the two groups.
CONCLUSION: There was no association between IEM and GPRD as well as between IEM and GERD. IEM alone cannot be considered as a definitive marker for reflux disease.

Abstract
OBJECTIVES To investigate the effect of esophageal mechanosensitive and chemosensitive stimulation on the magnitude and recruitment of peristaltic reflexes and upper esophageal sphincter (UES)-contractile reflex in premature infants. STUDY DESIGN Esophageal manometry and provocation testing were performed in the same 18 neonates at 33 and 36 weeks postmenstrual age (PMA). Mechanoreceptor and chemoreceptor stimulation were performed using graded volumes of air, water, and apple juice (pH 3.7), respectively. The frequency and magnitude of the resulting esophago-deglutition response (EDR) or secondary peristalsis (SP), and esophago-UES-contractile reflex (EUCR) were quantified. RESULTS Threshold volumes to evoke EDR, SP, or EUCR were similar. The recruitment and magnitude of SP and EUCR increased with volume increments of air and water in either study (P < .05). However, apple juice infusions resulted in increased recruitment of EDR in the 33 weeks group (P < .05), and SP in the 36 weeks group (P < .05). The magnitude of EUCR was also volume responsive (all media, P < .05), and significant differences between media were noted (P < .05). At maximal stimulation (1 mL, all media), sensory-motor characteristics of peristaltic and EUCR reflexes were different (P < .05) between media and groups. CONCLUSIONS Mechano- and chemosensitive stimuli evoke volume-dependent specific peristaltic and UES reflexes at 33 and 36 weeks PMA. The recruitment and magnitude of these reflexes are dependent on the physicochemical properties of the stimuli in healthy premature infants.

Abstract
BACKGROUND The objective of this study was to ascertain whether symptomatic gastroesophageal reflux disease (SGERD) without endoscopic evidence of inflammatory findings would develop into esophagitis. METHODS Observation by endoscopic examination was conducted annually for 5 years, using as subjects 497 patients among those who underwent gastroesophageal endoscopy in their health examination, but patients with findings of esophagitis and those who had undergone Helicobacter pylori eradication therapy were excluded. Of the 497 subjects, 47 were found to belong to the SGERD group and the remaining 450 to the negative GERD group. RESULTS Hiatus hernia was observed in 31.9% of the SGERD group and 10.9% of the negative GERD group, with the rate being significantly higher in the SGERD group. Esophagitis developed in 36.2% of the SGERD group and in 11.3% of the negative GERD group. The risk of esophagitis was significant in the presence of SGERD (P < 0.01), the absence of H. pylori infection (P < 0.01), the absence of gastric mucosa atrophy (P < 0.01), elevated triglycerides during the 5-year follow-up (P < 0.05), and an elevated body mass index (P < 0.05). Thus, even following adjustment for other factors, SGERD, with a demonstrated hazard ratio of 3.07, was a significant risk of reflux esophagitis. CONCLUSIONS The possibility is high that the presence of SGERD is a risk factor for esophagitis. In particular, individuals with hiatus hernia, those without H. pylori infection, and those who smoke and drink alcohol are prone to develop esophagitis.

Abstract
BACKGROUND Gastroesophageal reflux (GER) is frequently associated with pulmonary diseases. Esophageal acid-induced bronchoconstriction and recurrent microaspirations of gastric content are the proposed mechanisms. At present there is not a sensitive test available to prove a causal relationship between pulmonary symptoms and GER. In this study we aimed to investigate the value of a marker of aspiration: lipid-laden alveolar macrophage index (LLAM) in induced sputum, in the diagnosis of pulmonary symptoms highly suspected to be due to GER. METHODS Twenty-two patients with the endoscopic diagnosis of erosive esophagitis who had various pulmonary symptoms that could not be attributed to any apparent etiology constituted the study group. Fifteen healthy volunteers with no prior diagnosis of gastroesophageal and lung disease constituted the control group. Subjects were questioned for pulmonary and abdominal symptoms and underwent physical examination, chest radiography, pulmonary function tests, and sputum induction. Prepared cytospins were stained with oil red-O to detect cytoplasmic lipid droplets and LLAM index was calculated. RESULTS There was no statistically significant difference between the LLAM indexes of the study (1.9 +/- 3.3) and control group (4.2 +/- 4.5). LLAM index had a significant positive correlation with the duration of reflux symptoms (p=0.01, r=0.5). CONCLUSIONS LLAM index is not found to be a valuable method in the differential diagnosis of pulmonary symptoms suspected to be due to GER.

Abstract
INTRODUCTION Gastroesophageal reflux is commonly reported during high-intensity endurance exercise in otherwise healthy asymptomatic individuals. Although the mechanisms underlying this exercise-induced reflux are unknown, it most likely reflects a failure of the primary barrier to reflux, the lower esophageal sphincter (LES). The aim of this study was to determine the influence of exercise with and without ingestion of fluid on the LES barrier pressure in asymptomatic individuals. METHODS Seven recreational cyclists (five males) performed four 5-min bouts of cycle exercise at 90% VO2max, each separated by 1-3 min. Before, during, and after exercise, measurements were made of esophageal pressure (Pes), LES pressure (Ples), and gastric pressure (Pg). LES barrier pressure (Pb) was defined as the difference between Ples and Pg. Following exercise bouts 2 and 3, subjects ingested 600 and 200 mL of a sports drink, respectively. RESULTS Pb before exercise was 13.1 +/- 5.2 cm H2O (+/- SD), decreased to 6.5 +/- 4.6 cm H2O during each of the four bouts of high-intensity exercise (P < 0.05), and remained decreased at 7.4 +/- 3.5 cm H2O after exercise (P < 0.05). CONCLUSIONS High-intensity exercise reduces LES Pb during exercise in asymptomatic individuals. The magnitude of this exercise-induced impairment in LES function is unaffected by ingestion of a sports drink.

Abstract
The causal relationship between GERD and esophageal adenocarcinoma, although unclear just a few decades ago, now is established fairly well. The physiologic changes and the biocellular alterations of the damaged esophageal mucosa are documented better. Despite this knowledge, the dramatic increase in the incidence of esophageal cancer cannot be explained. The absolute risk of esophageal adenocarcinoma arising from GERD is low, and, at present, does not justify population-screening programs. Still, with the notion that adenocarcinoma of the esophagus is an aggressive cancer once documented, important questions still are in need of answers for patients suffering from reflux symptoms. Patients who have reflux disease are not necessarily symptomatic. It remains unclear if patients experiencing reflux symptoms should undergo mandatory endoscopy with biopsies at the esophagogastric junction. Furthermore, metaplasia of the lower esophagus often is not readily recognizable at endoscopy, and only biopsies can document abnormal histology. A severe and prolonged history of reflux always should orient to the possibility of a reflux-related columnar-lined esophagus. Once documented, Barrett's esophagus needs to be seen as a premalignant condition not necessarily leading to adenocarcinoma formation; despite their increased risk of tumor formation, most patients who have Barrett's esophagus die of other causes. During regular endoscopic follow-up, multilevel circumferential biopsies should document the evolution of the histologic changes in the lower esophagus and at the gastroesophageal junction of these patients. It is the only method available to document the appearance of dysplasia. It still is unclear if medicine or surgery provides the best quality of life and the best protection against the development of dysplasia and the possible progression toward adenocarcinoma formation when intestinal metaplasia is present in the esophagus.

Abstract
Aspiration of the oropharyngeal or gastric contents by elderly persons often leads to lower respiratory tract infections, such as aspiration pneumonia or pneumonitis. The existence of dysphagia and aspiration in elderly patients are important factors in the occurrence of aspiration pneumonia, but are not sufficient to cause aspiration pneumonia in the absence of other risk factors. Salivary flow and swallowing can eliminate Gram-negative bacilli from the oropharynx in healthy persons. However, elderly persons may have diminished production of saliva as a result of medications and oral/dental disease, leading to poor oral hygiene and oropharyngeal colonisation with pathogenic organisms. When dysphagic patients aspirate pathogenic bacteria while swallowing food or liquids, they must also have decreased defences, such as impaired immunity or pulmonary clearance, in order to develop aspiration pneumonia.Elderly patients with cerebrovascular disease often have dysphagia that leads to an increased incidence of aspiration. It was previously reported that patients with silent cerebral infarction affecting the basal ganglia were more likely to experience subclinical aspiration and an increased incidence of pneumonia. Basal ganglia infarction leads to the impairment of dopamine metabolism and, as a consequence, a decrease of substance P in the glossopharyngeal nerve and sensory vagal nerves. Therefore, dysphagia and a decreased cough reflex may be induced by the impairment of dopamine metabolism in some elderly patients with cerebrovascular disease, suggesting that pharmaceutical agents which modulate dopamine metabolism may be able to improve swallowing and the cough reflex in patients with basal ganglia infarction. The main strategy for controlling aspiration and aspiration-related pulmonary infection in the elderly is to prevent aspiration of pathogenic bacteria along with the oropharyngeal or gastric contents. Because aspiration pneumonia in the elderly is related to certain risk factors, including dysphagia and aspiration, effective preventive measures involve various approaches, such as pharmacological therapy, swallowing training, dietary management, oral hygiene and positioning.
