Abstract
There is a strong evidence that Helicobacter pylori infection is inversely associated with Barrett's esophagus. In a high-prevalence region of H. pylori, low rates of esophageal cancer and its precursor BE may indicate its preventive effect. The aim of this study is to determine the impact of H. pylori on characteristics of Barrett's esophagus. A total of 3317 outpatient upper endoscopy reports from 2013 to 2015 from an urban center in Azerbaijan from all patients with dyspepsia were retrospectively analyzed for patients with Barrett's esophagus. This was matched in a 1:2 ratio to age and gender matched control patients without Barrett's esophagus. The prevalence of H. pylori on Barrett's esophagus and the randomly selected control group were compared. There were 83 patients with BE and 167 control group cases. Biopsy-proven BE was diagnosed in 83 patients: 39 (47%) females, with mean age 43.1 ± 13.3 years. Of these, 13 (15.7%) had long segment and 70 (84.3%) had short segment Barrett's esophagus. A control group included 167 patients: 78 (46.7%) females, with mean age (45.8 ± 13.9). All patients were Caucasians. The rates of gastric inflammation, the presence of atrophy, and intestinal metaplasia in gastric specimens did not differ in patients versus controls. The prevalence of H. pylori was determined as 63.2% in male and 61.5 in female groups (odd ratio (OR) = 0.99 95%CI 0.97, 1.01; P = 0.22). Inflammation of gastric mucosa was strongly associated with the infection (67% vs. 33%; OR = 4.46 95% CI: 2.01, 9.92, P < 0.001). Atrophy was noted in majority of H. pylori-positive cases (OR = 1.43, 95% CI: 0.36, 5.65; P = 0.61). Gastric intestinal metaplasia was observed in 55.6% of H. pylori-positive patients and in 44.4% of negative individuals (OR = 0.74, 95% CI: 0.28, 1.94; P = 0.54). There was not a significant difference in the prevalence of HP in BE and control groups; 63.9% were positive for infection in BE cases and 61.7% of controls (OR = 1.10, 95% CI: 0.64, 1.90; P = 0.74). We found that neither presence of erosive esophagitis, length of BE nor dysplasia (45.5% of H. pylori-positive group, whereas 54.5%) was associated with the presence of the H. pylori infection (Table 1). In a predominantly Caucasian nation with a high prevalence of H. pylori gastritis, the presence of H. pylori was not inversely associated with the presence of Barrett's esophagus. These data challenge the mechanistic implications of this association.

Abstract
Infectious esophagitis is a leading cause of esophagitis worldwide. While esophageal infections have traditionally been associated with immunocompromised patients, these disorders are becoming increasingly recognized in immunocompetent individuals. The three most common etiologies of infectious esophagitis are Candida, herpes simplex virus, and cytomegalovirus. Human papilloma virus infection can also involve the esophagus in the form of ulcerative lesions and papillomas. Less common etiologies include various other fungal, bacterial, and viral organisms. This review provides a comprehensive update on risk factors, diagnosis, and management of both common and less common infections of the esophagus.

Abstract
With the emergence of eosinophilic esophagitis (EoE) as a common cause of food impaction (FI) and a presumed increase in incidence of EoE in the population, the effect on the incidence of FI has not been well described. The aim of this study is to describe the incidence of FI and endoscopic findings in these patients and the association with EoE. A population-based retrospective chart review of the Rochester Epidemiology Project database was performed to identify all patients within Olmsted County that presented with FI from 1976 to 2012. A review of all endoscopic findings, biopsy results, and demographic data was performed. 497 patients were identified with FI from 1976 to 2012. The overall incidence of FI has changed from 1976 to 2012 (Fig. 1) (P < 0.001). The peak incidence of 17.12 per 100,000 people occurred in the time period 1995 to 2000. Both the incidence of comorbid gastroesophageal reflux disease (GERD) and proton pump inhibitor (PPI) use increased over the time period of the study (P < 0.001 for both). Of these patients, 188 (46.7%) had no abnormalities on their endoscopy. The most common endoscopic finding was stricture in 71 (17.6%) patients followed closely by Schatzki's ring in 68 (16.9%) patients. 139 patients had biopsies performed within 2 years of FI and 50 (36.0%) of those were diagnosed with EoE. We present for the first time the changing incidence of FI over the last 35 years in a population-based setting. We also demonstrate the rise of EoE as an important clinical consideration in patients with FI.

Abstract
BACKGROUND The mechanism by which obesity leads to damage independent of reflux is unclear. We aimed to determine the influence of obesity on mean nocturnal baseline impedance (MNBI), a functional measure of the epithelial barrier, in the presence and absence of acid reflux, using ambulatory pH impedance measurements. METHODS Twenty-four-hour pH impedance studies performed off medications in Caucasian men with a normal endoscopic examination were assessed for level of acid exposure and MNBI. Four patient groups were studied: Group 1, Not obese and normal acid exposure; Group 2, Obese and normal acid exposure; Group 3, Not obese and increased acid exposure; and Group 4, Obese with increased acid exposure. RESULTS One hundred patients were studied (25 in each group). Mean esophageal mucosal impedance (MI) was substantially lower in obese patients without reflux (Group 2) and non-obese patients with reflux (Group 3) compared to normal controls (non-obese, no reflux, Group 1). MI was progressively lower in the distal (vs the proximal) esophagus in GER patients, compared to those without GER. This difference persisted in the presence or absence of obesity. In contrast, in obese patients, the mean MI was significantly lower throughout the esophagus when compared to the non-obese patients and also persisted in the presence and absence of accompanying reflux. Obesity and reflux were both independently negatively correlated with MI. CONCLUSION Obesity is associated with abnormal esophageal MNBI. In contrast to gastro-esophageal reflux, this decrease is pan-esophageal. These data may support a systemic mechanism by which obesity alters the esophageal barrier function.

Abstract
Achalasia is a relatively rare primary motor esophageal disorder, characterized by absence of relaxations of the lower esophageal sphincter and of peristalsis along the esophageal body. As a result, patients typically present with dysphagia, regurgitation and occasionally chest pain, pulmonary complication and malnutrition. New diagnostic methodologies and therapeutic techniques have been recently added to the armamentarium for treating achalasia. With the aim to offer clinicians and patients an up-to-date framework for making informed decisions on the management of this disease, the International Society for Diseases of the Esophagus Guidelines proposed and endorsed the Esophageal Achalasia Guidelines (I-GOAL). The guidelines were prepared according the Appraisal of Guidelines for Research and Evaluation (AGREE-REX) tool, accredited for guideline production by NICE UK. A systematic literature search was performed and the quality of evidence and the strength of recommendations were graded according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE). Given the relative rarity of this disease and the paucity of high-level evidence in the literature, this process was integrated with a three-step process of anonymous voting on each statement (DELPHI). Only statements with an approval rate >80% were accepted in the guidelines. Fifty-one experts from 11 countries and 3 representatives from patient support associations participated to the preparations of the guidelines. These guidelines deal specifically with the following achalasia issues: Diagnostic workup, Definition of the disease, Severity of presentation, Medical treatment, Botulinum Toxin injection, Pneumatic dilatation, POEM, Other endoscopic treatments, Laparoscopic myotomy, Definition of recurrence, Follow up and risk of cancer, Management of end stage achalasia, Treatment options for failure, Achalasia in children, Achalasia secondary to Chagas' disease.

Abstract
Previous studies reported increased eosinophilic esophagitis (EoE) incidence in children. It is unclear whether this reported increased EoE incidence is true or due to increased recognition and diagnostic endoscopy among children. A population-based study that evaluated EoE incidence in OC, Minnesota, from 1976 to 2005 concluded that EoE incidence increased significantly over the past three 5-year intervals (from 0.35 [range: 0-0.87] per 100,000 person-years for 1991-1995 to 9.45 [range: 7.13-11.77] per 100,000 person-years for 2001-2005). The aim of this study is to assess the change of incidence and characteristics of EoE in children in the same population between 2005 and 2015 and compare the findings to those reported in the previous study. We retrospectively reviewed the electronic medical records from Olmsted Medical Center and Mayo Clinic between 2005 and 2015, using Rochester Epidemiology Project (REP) resources. All children with EoE diagnosis based on the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN) guidelines were included. The incidence and characteristics of children with EoE during the study period were compared to those diagnosed between 1995 and 2005. The incidence of EoE in children adjusted for age and sex was 5.31 per 100,000 population person-years in 1995, 15.2 in 2005, and 19.2 in 2015. Change in annual incidence and seasonal variation were not significant, (P = .48) and (P = .32), respectively. Between 2005 and 2015, 73 children received an EoE diagnosis (boys 49; 67%) compared to 16 children (boys 10; 62.5) between 1995 and 2005. Mean (SD) age at diagnosis was 7.5 (5.2) and 12.8 (4.3) years, respectively. Symptoms differed by age of presentation, with vomiting the most common in children younger than 5 years (41.1% and 43.5%) and dysphagia in those older than 5 years (35.6% and 60.9%). The incidence of EoE was not increased for any specific age-group during the study period (P = .49). This study showed increased incidence of EoE in children in Olmsted County between 2005 and 2015 compared to the incidence between 1995 and 2005 (5.31 per 100,000 population person-years in 1995, 15.2 in 2005, and 19.2 in 2015). However, between 2005 and 2015, the change of incidence was not statically significant, (P = .48) despite the steady increase of EGD performed during the same time frame (64 in 2005 to 144 in 2015). By comparing children diagnosed between 2005 and 2015 to those diagnosed between 1995 and 2005, the mean age at diagnosis was younger in the former group, 7.5 versus 12.8 years. Vomiting replaced dysphagia as the most common clinical presentation. Otherwise, the presenting symptom of EoE in children remained consistent across specific age groups.

Abstract
BACKGROUND Current management of refractory benign oesophageal strictures with endoscopic dilations and stenting leads to resolution of dysphagia in only 30% of patients. Oesophageal self-dilation may be an alternative. AIM To evaluate the efficacy and safety of oesophageal self-dilation at a tertiary referral centre. METHODS We conducted a retrospective review of patients with refractory benign oesophageal strictures who participated in oesophageal self-dilation at Mayo Clinic (Rochester, MN, USA) between 2003 and 2017. Clinical data including stricture characteristics, Dakkak and Bennett Dysphagia Score, number and dates of endoscopies, and complications were collected. A two-tailed paired Student's t test was used to compare the measures of efficacy, with differences considered significant at a 5% probability level. RESULTS We identified 52 patients with refractory strictures treated with self-dilation. The median number of endoscopic interventions was reduced from 9.5 (range 5-30) to 0 (range 0-3) within 12 months before and after self-dilation, respectively (P < 0.0001). A median intervention-free interval of 417 days (IQR 256-756 days) was observed. The mean dysphagia score at baseline was 2.5 (95% CI 2.2-2.8) and 0.33 (95% CI 0.11-0.53) after self-dilation. 23 of 27 (85%) patients who received enteral nutrition prior to self-dilation had their feeding tubes removed. CONCLUSIONS Oesophageal self-dilation is an effective way of maintaining oesophageal patency in refractory benign oesophageal strictures, with safety comparable to current standard of care. Prospective studies are needed to further validate the role of self-dilation in treatment of refractory benign oesophageal strictures.

Abstract
BACKGROUND The validity of the eosinophilic oesophagitis (EoE) histologic scoring system (EoEHSS) has been demonstrated, but only preliminary reliability data exist. AIM Formally assess the reliability of the EoEHSS and additional histologic features. METHODS Four expert gastrointestinal pathologists independently reviewed slides from adult patients with EoE (N = 45) twice, in random order, using standardised training materials and scoring conventions for the EoEHSS and additional histologic features agreed upon during a modified Delphi process. Intra- and inter-rater reliability for scoring the EoEHSS, a visual analogue scale (VAS) of overall histopathologic disease severity, and additional histologic features were assessed using intra-class correlation coefficients (ICCs). RESULTS Almost perfect intra-rater reliability was observed for the composite EoEHSS scores and the VAS. Inter-rater reliability was also almost perfect for the composite EoEHSS scores and substantial for the VAS. Of the EoEHSS items, eosinophilic inflammation was associated with the highest ICC estimates and consistent with almost perfect intra- and inter-rater reliability. With the exception of dyskeratotic epithelial cells and surface epithelial alteration, ICC estimates for the remaining EoEHSS items were above the benchmarks for substantial intra-rater, and moderate inter-rater reliability. Estimation of peak eosinophil count and number of lamina propria eosinophils were associated with the highest ICC estimates among the exploratory items. CONCLUSION The composite EoEHSS and most component items are associated with substantial reliability when assessed by central pathologists. Future studies should assess responsiveness of the score to change after a therapeutic intervention to facilitate its use in clinical trials.

Abstract
BACKGROUND Although major manometric abnormalities, the significance of esophagogastric junction outflow obstruction (EGJOO) and hypercontractile esophagus (HE) is poorly understood. We sought to determine long term outcomes for EGJOO and HE. METHODS High-resolution impedance manometry (HRIM) studies conducted from 5/30/2012 to 8/1/2014 consistent with EGJOO and HE and normal studies from 5/30/12 to 11/1/12 were identified. Standardized follow up was conducted with a phone survey utilizing the impact dysphagia questionnaire (IDQ-10). KEY RESULTS 56 EGJOO, 40 HE patients and 33 controls were identified. Structural evaluation with EGD and esophagram did not differ among groups. Use of opiates in EGJOO (P<.05) and of anticholinergics in EGJOO and HE patients was more prevalent than in controls (P<.005). Dysphagia was more common in EGJOO (P<.05) and chest pain more common in HE (P<.005) at presentation. While HE patients were more likely to be symptomatic (P<.05), the majority of EGJOO and HE patients overall were asymptomatic at a mean 2.8 years follow up without medical or procedural intervention in the majority (72.5%). Symptom persistence at follow up was predicted by maximum distal contractile integral (DCI) and IRP in both EGJOO and HE (P<.05). CONCLUSIONS & INFERENCES The majority of patients with EGJOO and HE appear to have a benign clinical course similar to controls in the absence of specific treatment. However, the combination of abnormal IRP and DCI in both HE and EGJOO appears to discriminate an important subset of patients who may benefit from treatment. Further refinement of manometric criteria may therefore provide more useful clinical definitions of EGJOO and HE.

Abstract
BACKGROUND Baseline impedance measured with ambulatory impedance pH monitoring (MII-pH) and a mucosal impedance catheter detects gastroesophageal reflux disease (GERD). However, these tools are limited by cost or patient tolerance. We investigated whether baseline impedance measured during high-resolution impedance manometry (HRIM) distinguishes GERD patients from controls. METHODS Consecutive patients with clinical HRIM and MII-pH testing were identified. Gastroesophageal reflux disease was defined by esophageal pH <4 for ≥5% of both the supine and total study time, whereas controls had an esophageal pH <4 for ≤3% of the study performed off PPI. Baseline impedance was measured over 15 seconds during the landmark period of HRIM and over three 10 minute intervals during the overnight period of MII-pH. KEY RESULTS Among 29 GERD patients and 26 controls, GERD patients had a mean esophageal acid exposure time of 22.7% compared to 1.2% in controls (P<.0001). Mean baseline impedance during HRIM was lower in GERD (1061 Ω) than controls (2814 Ω) (P<.0001). Baseline mucosal impedance measured during HRIM and MII-pH correlated (r=0.59, P<.0001). High-resolution esophageal manometry baseline impedance had high diagnostic accuracy for GERD, with an area under the curve (AUC) of 0.931 on receiver operating characteristics (ROC) analysis. A HRIM baseline impedance threshold of 1582 Ω had a sensitivity of 86.2% and specificity of 88.5% for GERD, with a positive predictive value of 89.3% and negative predictive value of 85.2%. CONCLUSIONS & INFERENCES Baseline impedance measured during HRIM can reliably discriminate GERD patients with at least moderate esophageal acid exposure from controls. This diagnostic tool may represent an accurate, cost-effective, and less invasive test for GERD.

Abstract
BACKGROUND Most follow-up studies of achalasia are limited to <5 years. AIM To study the long-term efficacy of pneumatic dilation (PD) and myotomy in achalasia at least 10 years after treatment. METHODS We performed a retrospective cohort study of achalasia patients with >10 years follow-up after initial myotomy or pneumatic dilation. Symptom recurrence which required repeat dilation or surgery was compared between pneumatic dilation and myotomy. RESULTS One hundred and fifty patients (112 myotomy, 38 pneumatic dilation) of similar characteristics were studied. The mean duration of follow-up after initial treatment was 17.5 ± 7.2 years (10-40 years). Symptoms recurrence rate was 60.7% (100% pneumatic dilation patients vs. 47.3% myotomy), hazard ratio 0.24 demonstrating a lower need for repeat dilation or surgery with myotomy than pneumatic dilation (P = 0.008). All pneumatic dilation patients underwent myotomy in 4 ± 4 (0-16 years). Forty of 53 myotomy patients had symptom recurrence prompting further treatment: 16 pneumatic dilation, 11 myotomy and 13 both. The mean time to repeat procedure was 6.9 years (0-40). The myotomy group required fewer dilations and/or surgeries than the pneumatic dilation group (1.6 vs. 3.6, P < 0.001). 13 patients (10.1%) progressed to end-stage achalasia (five myotomy, eight pneumatic dilation) over 40 years. At last follow-up, 57/62 (92%) patients had absent or mild dysphagia, 53/62 (85%) patients had regurgitation less than once per week and 37 (60.7%) had heartburn episodes <1/week similar for pneumatic dilation and myotomy (P = 0.27). CONCLUSION Although the majority of patients treated for achalasia do well after decades of treatment, most patients may need a series of endoscopic and/or surgical procedures to maintain effective symptom control.

Abstract
BACKGROUND Although eosinophilic oesophagitis (EoE) is putatively mediated by an abnormal response to food antigen, the oesophagus is considered relatively impermeable to large molecules. AIM To assess whether food antigens penetrate the oesophageal mucosa in patients with EoE. METHODS Anti-gliadin staining was performed in three groups: active EoE, inactive EoE and EoE patients on a low or gluten free diet. To appraise the specificity of our results, we also performed gliadin staining on six patients without oesophageal disease who were consuming gluten. The groups with EoE on gluten also underwent endoscopic infusion with gluten containing soy sauce and repeat biopsies during the endoscopy. We measured eosinophil density, dilated intercellular spaces (on a 0-4+ scale) and gliadin in oesophageal mucosa by immunofluorescence. RESULTS Patients with active EoE had significantly greater epithelial density of anti-gliadin staining when compared to inactive EoE (P < 0.0065) and gluten-free patients (P < 0.0008) at baseline and after soy infusion. Gliadin was not detected in non-EoE control patients. The distribution of gliadin was both cytoplasmic and nuclear. There was good correlation of dilated intercellular spaces grade and total gliadin staining intensity (r = 0.577, P = 0.0077). Acute oesophageal perfusion of a commercial gliadin-rich soy sauce did not lead to an increase in gliadin staining in active or inactive EoE. CONCLUSION These findings suggest, although do not prove, that antigen penetration in active eosinophilic oesophagitis might be facilitated by impairment of epithelial integrity.

Abstract
BACKGROUND Oesophageal lichen planus is an idiopathic inflammatory disorder characterized by significant oesophageal stricturing. Oesophageal lichen planus is a rare, difficult to diagnose, and likely an under recognized disease. As a result, there is no standardized approach to therapy and treatment strategies vary. AIM To examine the utility of topical steroid therapy (fluticasone or budesonide) in the management of oesophageal lichen planus. METHODS A retrospective chart review was conducted of patients diagnosed with oesophageal lichen planus who underwent baseline and follow up endoscopy pre and post topical steroid therapy between 1995 and 2016 at Mayo Clinic, Rochester MN. Average time between upper GI endoscopy was 3.2 months (0.7-11.7). Swallowed steroid preparations included fluticasone 880 μg twice daily or budesonide 3 mg twice daily. Patients were reviewed for symptomatic response to therapy using the Dakkak-Bennett dysphagia score (0-4, no dysphagia to total aphagia). Pre- and post-endoscopic findings were assessed. Additional baseline demographic, endoscopic, and histologic data were also obtained. RESULTS We identified 40 patients who met the inclusion criteria. A significant reduction in median dysphagia score from 1 (0-4) to 0 (0-3) after steroid therapy (P < 0.001) was noted. 62% of patients reported resolution of their dysphagia after receiving topical corticosteroids. 72.5% had an endoscopic response to steroid therapy. CONCLUSION Topical swallowed budesonide or fluticasone appear to effective treatment for oesophageal lichen planus.

Abstract
Secondary achalasia may result from diseases that either infiltrate or compress the lower esophageal sphincter to create an increased high-pressure zone and subsequent esophageal body changes. With bariatric surgery, a potential high-pressure zone is created by a sleeve, band, or bypass just distal to the esophagus. We report four patients who years after a bariatric procedure developed dysphagia followed by esophageal body radiographic and/or manometric features of achalasia. In addition, each of these patients responded symptomatically to endoscopic or surgical therapy either which lowered this high-pressure zone. Furthermore, review of prior cases in the literature suggests this has occurred before. Physicians should be aware of this association but further study is needed on its true prevalence.

Abstract
BACKGROUND The proportion of oesophageal adenocarcinoma that is detected concurrently with initial Barrett's oesophagus diagnosis is not well studied. AIM To compare the proportion of prevalent adenocarcinoma vs. incident adenocarcinoma found during surveillance of Barrett's. METHODS We performed a systematic search of MEDLINE, EMBASE and Web of Science (from their inception to 31 May 2015) for cohort studies in adults with Barrett's (nondysplastic Barrett's ± Barrett's with low-grade dysplasia) with minimum average follow-up of 3 years, and providing numbers of prevalent adenocarcinoma detected (concurrently with Barrett's diagnosis and up to 1 year afterwards) vs. incident adenocarcinoma detected (greater than 1 year after Barrett's diagnosis). Pooled weighted proportions of prevalent and incident adenocarcinoma were calculated, using a random effects model. RESULTS On meta-analysis of 13 studies reporting on 603 adenocarcinomas in 9657 Barrett's patients, 85.1% of adenocarcinomas were classified as prevalent [95% confidence interval (CI), 78.1-90.2%) and 14.9% as incident (95% CI, 9.8-21.9%), with substantial heterogeneity (I(2) = 66%). Among nine studies reporting on 787 high-grade dysplasia and oesophageal adenocarcinomas in 8098 Barrett's patients, the proportion of prevalent high-grade dysplasia-oesophageal adenocarcinoma was similar at 80.5% (95% CI, 68.1-88.8%, I(2) = 87%). These results remained stable across multiple subgroup analyses including study quality, setting, duration of follow-up and presence of baseline dysplasia. CONCLUSIONS In our meta-analysis, four of five patients diagnosed with adenocarcinoma or high-grade dysplasia at index endoscopy or within 1 year of Barrett's follow-up were considered to be prevalent cases. Continued efforts are needed to identify patients with Barrett's before the development of adenocarcinoma.

Abstract
BACKGROUND To date there have been no clear features that aid in differentiating patients with eosinophilic oesophagitis (EoE) from PPI-responsive oesophageal eosinophilia (PPI-REE). However, barium swallow roentgenography is a more sensitive and specific measure to detect subtle fibrostenotic remodeling changes present in EoE. We aim to characterise any clinical, endoscopic, histiological or barium roentgenographic differences between EoE and PPI-REE. AIM To characterise any clinical, endoscopic, histiological or barium roentgenographic differences between EoE and PPI-REE. METHODS We performed a retrospective cohort analysis on data collected from a tertiary referral centre population from 2010 to 2015. Data from 66 patients with EoE and 28 patients with PPI-REE were analysed. Cases were adults who met consensus guidelines for EOE, and had a barium swallow study within 6 months of the index endoscopy. Clinical, endoscopic, histiological and barium swallow findings were collected. RESULTS Patients with EoE reported similar characteristics as PPI-REE patients, except EoE patients were younger (35.6 vs. 46.6 years; P = 0.011), had earlier symptom onset (29.0 vs. 38.0 years; P = 0.026), and smaller oesophageal diameters on barium swallow (19.5 mm vs. 20; P = 0.042). Patients with EoE were more likely to have distal strictures (EoE 77% vs. 25%; P = 0.02) and, importantly, a greater likelihood of small calibre oesophagus (51.5% vs. 17.9%; P = 0.002). Moreover, EoE patients had a higher probability of developing small calibre oesophagus after 20 years of symptoms (72.3% vs. 30.2%; P = 0.074) compared to PPI-REE patients. CONCLUSIONS When compared with eosinophilic oesophagitis, PPI-REE patients demonstrate findings that suggest PPI-responsive oesophageal eosinophilia to be a later onset, less aggressive form of oesophageal stricturing disease than eosinophilic oesophagitis.

Abstract
BACKGROUND While high resolution esophageal manometry combined with impedancometry has demonstrated that gastric pressurizations lead to rumination, the contribution of upper esophageal sphincter (UES) and esophagogastric junction (EGJ) function to rumination is unclear. Behavioral therapy with diaphragmatic breathing (DB) can reduce rumination. We aimed to evaluate the pressures in the stomach, EGJ and UES during rumination and the effects of DB augmented with biofeedback therapy. METHODS Sixteen patients with rumination were studied with manometry and impedancometry before and after a meal. The postprandial assessment comprised three periods: before, during, and after DB augmented with biofeedback therapy. KEY RESULTS All patients had postprandial rumination, which was associated (p < 0.001) with increased gastric pressure and reversal of the postprandial gastroesophageal pressure gradient from -4 (-43 to 18) before to 20 (7-79) mmHg during rumination. The EGJ pressure was lower (p < 0.001) during gastric pressurizations that were associated with rumination vs those that were not. The UES also relaxed, almost completely, during rumination. Patients had a median (range) of 5 (2-10) rumination episodes before, 1 (0-2) (p < 0.001) during, and 3 (1-5) after (p < 0.001 vs during) diaphragmatic breathing. During manometry and impedancometry, DB was well-tolerated and learned within 5 min. Diaphragmatic breathing increased EGJ pressure (p < 0.001) and restored a negative gastroesophageal pressure gradient (-20 mmHg [-80 to 7]). CONCLUSIONS & INFERENCES Diaphragmatic breathing aided with high resolution esophageal manometry is well-tolerated, effective and averts the gastroesophageal pressure disturbance that leads to rumination.

Abstract
High-resolution manometry identifies three subtypes of achalasia. However, type 3 differs from classic achalasia. Although opiates affect esophageal motility, opiate use and achalasia have not been studied. Patients with a new diagnosis of achalasia at Mayo Clinic Rochester between June 1, 2012 and January 3, 2014 were identified. Clinical records were reviewed to assess symptoms, opiate use, and therapy. Fifty-six patients with achalasia were identified, 14 (25%) were on opiates. Opiate prescription was unrelated to achalasia in all cases, with chronic back and joint pain constituting the majority. Of patients on opiates, five (36%) had type 3 achalasia compared with four (10%) not on opiates (P = 0.02). No patients on opiates had type 1 achalasia. Clinical presentation did not differ with opiates, although those on opiates were more likely to report chest pain (39 vs. 14%, P = 0.05) and less likely to have esophageal dilation (62 vs. 82%, P = 0.13), none with greater than 5-cm diameter. Contractile vigor was greater with opiate use, with distal contractile integral of 7149 versus 2615.5 mmHg/cm/second (P = 0.08). Treatment response was inferior on opiates, with persistent symptoms in 22% compared with 3% without opiates (P = 0.06). Opiate use is common in type 3 achalasia, with the majority of patients on opiates. No patients on opiates were diagnosed with type 1 achalasia. Manometric findings of type 3 achalasia mimic those induced by opiates, suggesting a physiologic mechanism for opiate induced type 3 achalasia. Treatment outcome is inferior with opiates, with opiate cessation perhaps preferable. Further studies assessing opiate use and achalasia are needed.

Abstract
Achalasia is an important but relatively uncommon disorder. While highly effective therapeutic options exist, esophageal cancer remains a long-term potential complication. The risk of esophageal cancer in achalasia remains unclear, with current guidelines recommending against routine endoscopic screening. However, given limited data and conflicting opinion, it is unknown whether consensus regarding screening practices in achalasia among experts exists. A 10-question survey to assess screening practices in achalasia was created and distributed to 28 experts in the area of achalasia. Experts were identified based on publications and meeting presentations in the field. Survey responses were received from 17 of 28 (61%) experts. Wide geographic distribution was seen among respondents, with eight (47%) from Europe or Australia, seven (41%) from the United States, and two (12%) from Asia. Screening for esophageal cancer was inconsistent, with nine (53%) experts endorsing the practice and eight (47%) not. Screening practices did not differ among geographic regions. No consensus regarding the risk for esophageal cancer in achalasia was seen, with three experts reporting no increased risk compared with the general population, eight experts a lifetime risk of 0.1-0.5%, three experts a 0.5-1% risk, two experts a 1-2% risk, and one expert a 3-5% risk. However, these differences in perception of risk did not influence screening practices. Upper endoscopy was utilized among all experts who endorsed screening. However, practices still varied with screening commencing at or within 1 year of diagnosis in two practices compared with 5 and 10 years in three respective practices each. Surveillance intervals also varied, performed every 2 years in four practices, every 3 years in four practices, and every 5 years in one practice. Practice variation in the management of achalasia itself was also seen, with initial treatment with Heller myotomy endorsed by eight experts, pneumatic dilation by five experts, and two each endorsing peroral endoscopic myotomy or no specific preference. In addition, while 82% (14/17) of experts endorsed long-term follow up of patients, no consensus regarding long-term follow up existed, with annual follow up in eight practices, every 3-6 months in three practices, and every 2 years in three practices. Large practice variation in the long-term management of achalasia exists among experts in the field. Only a slight majority of experts endorse screening for esophageal cancer in achalasia, and no consensus exists regarding how surveillance should be structured even among this group. Interestingly, the lack of consensus on cancer screening parallels a lack of agreement on initial treatment of achalasia. These findings suggest a need for greater homogeneity in the management of longstanding achalasia and cancer screening. Further, this study highlights the need for more data on this topic to foster greater agreement.

Abstract
Chronic belching can be a difficult and socially disabling symptom often attributed to reflux with poor response to therapy. In patients where aerophagia is identified as a clear cause, treatment with baclofen may not be tolerated, and biofeedback therapy is time-intensive and may still not be effective. In this pilot study, an office-based easy-to-perform method based on sustained glottal opening was used in five patients with chronic belching, in whom reflux and other causes had been excluded. Treatment consisted of having the patient breathe slowly and diaphragmatically with his or her mouth open during supine, then sitting periods to prevent belching. When this was successful, patients were then counseled on continuing this breathing with mouth slightly ajar as an outpatient using this persistently. Wide mouth opening was used for rescue therapy of belching attacks. All five patients responded to the office-based therapy with complete cessation of belching during the visit. At 1-month follow up, four patients remained asymptomatic. One patient was asymptomatic but for two breakthrough attacks easily managed with the protocol. A simple office-based procedure based on complete glottal opening can be curative for a subset of patients with chronic eructation secondary to repetitive air swallowing.

Abstract
BACKGROUND Recent advances in eosinophilic oesophagitis (EoE) have confirmed the existence of a new disease phenotype, proton pump inhibitor (PPI)-responsive oesophageal eosinophilia (PPI-REE). AIM To summarise evidence supporting the use of PPI therapy in patients with suspected EoE (oesophageal dysfunction plus >15 eos/HPF in oesophageal biopsies). METHODS A literature search was conducted through MEDLINE, using the MeSH search terms 'eosinophilic oesophagitis', 'proton pump inhibitors' and 'oesophageal eosinophilia'. Relevant articles and their reference lists were identified through manual review. RESULTS Ten articles, including 258 patients with suspected EoE (152 children, 106 adults) undergoing clinico-histological re-evaluation after PPI therapy, were identified. In children, clinical response ranged from 78% to 86% and histological remission from 23% to 40%. In adults, symptom response ranged from 25% to 80% and histological remission from 33% to 61%. Among PPI-REE patients with oesophageal pH-monitoring, 35 showed pathological and 10 normal studies. PPI-REE was significantly commoner with documented gastro-oesophageal reflux disease (GERD) when compared to patients with negative pH monitoring (70% vs. 29%, P < 0.001). Symptom improvement/resolution occurred in 50-85% of patients without histological remission on PPI therapy. Six PPI-REE patients demonstrated clinico-histological relapse on PPI therapy. CONCLUSIONS At least one third of patients with suspected EoE achieve clinico-histological remission on PPI therapy. Response is more limited in children compared with that in adults. pH monitoring does not accurately predict response to PPI therapy, albeit histological remission is significantly higher, up to 70%, upon documented GERD. Symptom improvement is common with PPI therapy despite persistent eosinophilic infiltration.

Abstract
BACKGROUND Patients with eosinophilic oesophagitis (EoE) commonly have asthma and atopy. AIMS To determine the predictive factors of EoE in patients with asthma. METHODS A retrospective analysis of a large database identified 156 asthma patients with EoE and 276 patients without EoE between 2000 and 2010. Clinical and laboratory characteristics were first analyzed in half of each group. Significant differences and modelling were then applied to the other half of each group in a split half analysis. RESULTS Odds ratios and P-values found to predict the presence of EoE in asthma patients were: allergic vs. non-allergic asthma (4.07, <0.01), food allergies (45, <0.01), allergic rhinitis (2.13, =0.01) and peripheral eosinophilia (4.51, <0.01). The use of inhaled corticosteroids was negatively associated with EoE (0.41, <0.01) for asthma patients and (0.37, P < 0.01) for allergic type asthma patients. EoE patients were also younger (27.4 vs. 41.6 years old, P < 0.01). By logistic regression analysis, allergic asthma, presence of peripheral eosinophilia and use of inhaled steroids remained significant. From these parameters, a 3.5-point scoring system model for EoE in asthma was formed with an ROC = 0.787 on split analysis. CONCLUSIONS In descending order, peripheral eosinophilia, allergic asthma and allergic rhinitis are associated with EoE in patients with asthma. Steroid inhalers appear to have a protective effect against EoE. An accurate and simple scoring system can be used as a screening tool to predict the presence of EoE in patients with asthma and dysphagia. EoE should be viewed as part of a generalised allergic phenotype rather than isolated oesophageal disease.

Abstract
Achalasia secondary to neoplasia is an uncommon entity, but recognition is paramount given the concern of missing a cancer diagnosis. Most case series of secondary achalasia occurred in prior decades raising the question of whether the underlying neoplastic causes have changed. All cases of achalasia secondary to neoplasia were reviewed at the Mayo Clinic from 2000 to the present. Cases were assessed for underlying cause of achalasia, whether achalasia was the primary presentation and demographic and clinical factors. Seventeen patients with achalasia secondary to neoplasia were identified. This was 1.5% of all patients with achalasia seen. The most common causes were adenocarcinoma of the esophagus, followed by breast and non-small cell lung cancer. No cases of gastric cancer were identified. Most patients had weight loss and rapid onset of symptoms but could not clearly be distinguished from primary achalasia. Nine patients presented with achalasia, whereas eight patients had known neoplasia. Five of these patients had a positive paraneoplastic panel suggestive of a paraneoplastic syndrome. Prognosis was generally poor except for patients with esophageal leiomyomatosis. This case series demonstrates a changing differential diagnosis for achalasia secondary to neoplasia with a higher number of patients presenting with a known primary and with a paraneoplastic syndrome. Awareness of secondary achalasia and its differentiation from primary causes is still essential.

Abstract
Markedly increased esophageal eosinophils are associated with allergy- or reflux-based eosinophilic esophagitis. Other known disorders that cause this entity are unusual. To characterize the clinical, endoscopic, and histological findings of patients who develop marked esophageal eosinophilic infiltration after ablative therapy for Barrett's dysplasia. All patients who underwent endoscopic ablation of Barrett's esophagus between 1991 and 2009 with photodynamic therapy or radio frequency were screened for a pathologic descriptor of 'eosinophils' on biopsy. Patients whose biopsies demonstrated >15 eosinophils per high power (HPF) field in squamous epithelium after ablation were reviewed and included in the study group. Thirteen of 385 (3.4%) patients underwent ablation for Barrett's esophagus and subsequently had large numbers of intraepithelial eosinophils. All patients had long segment Barrett's (mean 8.0 cm) with low- or high-grade dysplasia or adenocarcinoma. All had undergone photodynamic therapy as their form of ablation. No patients had typical symptoms or endoscopic findings of eosinophilic esophagitis. Eleven patients were on proton pump inhibitors. The time between ablation and onset of esophageal eosinophilia ranged from 83 to 692 days. Intraepithelial eosinophil counts ranged from 30 to 150/HPF (mean 90). The majority of cases showed eosinophilic degranulation, spongiosis, increased papillary height, and basal zone thickening. The natural history of esophageal eosinophilia was variable after ablation, persisting consistently or sporadically on biopsy for up to 6 years. Ablation for Barrett's dysplasia can be followed rarely by eosinophil infiltrates with a histological resemblance to allergy-based eosinophilic esophagitis, but lacking dysphagia. The pathophysiology is unknown.

Abstract
BACKGROUND The consensus statements for eosinophilic oesophagitis recommend that ambulatory pH monitoring is one means of determining if gastro-oesophageal reflux is the cause of oesophageal eosinophilia and should guide pharmacological therapy. AIM To evaluate prospectively the accuracy of pH monitoring as a predictor of endoscopic, histological and symptomatic response in patients with oesophageal eosinophilia. METHODS We conducted a prospective trial in which patients with oesophageal eosinophilic infiltration with ≥15 eos/hpf underwent a 24-h pH study and were placed in one of two treatment arms for 6 weeks based on positive or negative results. Patients with abnormal acid exposure were treated with esomeprazole 40 mg twice daily and others were treated with oral viscous budesonide 1 g twice daily. Response to treatment was assessed by oesophageal histology (<5 eos/hpf) and symptoms. RESULTS A total of 51 patients were enrolled in the study. The average patient age was 39 years and 31 patients (61%) were male. The average number of eosinophils per hpf, prior to study enrolment was 41.2 (range 15-140, s.d. 27.7). Nineteen (37%) had positive pH studies and 32 (63%) had negative pH studies. Eighteen patients completed treatment with esomeprazole. Only eleven (61%) had histological response and, of these eleven, five (46%) had symptomatic improvement. A total of 28 patients with normal acid exposure completed treatment with budesonide. Only 16 (57%) had histological and 11 (69%) had symptomatic improvement. CONCLUSION In this prospective trial of pH-guided treatment, neither positive nor negative results of initial pH monitoring accurately predicted response to therapy.

Abstract
Granular cell tumors (GCT) are uncommon neoplasms. There is controversy regarding the endoscopic diagnosis and treatment of esophageal GCT. We studied the endoscopic diagnosis and management of esophageal GCT among 23 patients identified in a single-institution pathology database. Medical records, pathology, and endoscopic images were reviewed. All patients underwent endoscopy and endoscopic ultrasonography (EUS), and endoscopic resection was performed in 10 patients. Seven of 23 patients had more than one esophageal GCT. Only six lesions exhibited a classic yellow discoloration. Among patients with a single GCT, three, four, and nine lesions were located in the proximal, middle, and distal esophagus, respectively. EUS showed hypoechoic, smooth-edged lesions usually confined to deep mucosa and submucosa. Standard forceps biopsy was diagnostic in 19 of 23 patients (83%). Ten GCT ≤ 10 mm in diameter underwent successful endoscopic mucosal resection without complication. The endoscopic appearance, location, and number of esophageal GCT are highly variable. Histological proof is still necessary for the differential diagnosis of this rare neoplasm. Endoscopic forceps biopsy is usually diagnostic. Endoscopic resection appears safe and effective in selected cases with lesions ≤ 10 mm.

Abstract
BACKGROUND Pneumatic dilation has re-emerged as a first line treatment for achalasia, but conclusions are limited by the relatively small numbers of patients studied and the lack of long term follow-up. AIM To summarise and analyse 29 available studies evaluating pneumatic dilation for achalasia with focus on efficacy, rate or perforation and dilation technique. METHODS A literature search for all studies, in which pneumatic dilation was performed for treatment of achalasia, was conducted. Studies, in which clear endpoints of efficacy of single dilation sessions over a period of years, were chosen. RESULTS The response for a single dilation session was 66% at 1 year and 59, 53, 50 and 25% at 2, 3, 5 and 10 years respectively. Use of a Rigiflex dilator and multiple dilations during the initial treatment improved efficacy. Overall perforation rate was only 2% (24/1358) of which only 1% required surgery. Use of multiple dilations led to increased perforation risk. The method of dilation used with regard to balloon size, pressure used, dilation times and single or multiple dilations varied in almost every study. CONCLUSIONS Pneumatic dilation is safer than commonly thought and efficacious, although multiple dilations will be needed over a lifetime in most patients. Standardisation of the technique should be attempted.

Abstract
BACKGROUND Exclusion of the meal during ambulatory pH monitoring presumes that a meal completely buffers gastric acid and reflux of acidic food content cannot be distinguished from gastric acid. However, the ability of a meal to completely buffer gastric acid remains unclear. AIM To determine the effect of a weakly acid meal on gastric buffering and oesophageal acid exposure. METHODS Patients undergoing multichannel intraluminal impedance pH studies were given a standard weakly acidic meal (pH = 5.9). Gastric and oesophageal pH was measured during the meal and in 15 min intervals for 2 h postprandially. RESULTS The study included 30 patients, with pathological acid reflux detected in 18 patients. Complete gastric buffering occurred in seven patients (23%) and was lost in all patients within 75 min of the meal. Oesophageal acid was detected in 33% of patients within 30 min of the meal and 81% of patients during the 2 h postprandial period. Postprandial oesophageal acid exposure was greater in patients with pathological acid reflux (9 ± 2.7% vs. 1.7 ± 0.8% P = 0.05) with a trend towards more incomplete gastric acid buffering and significant differences when measuring weak acid reflux (pH 4-5). Acid reflux rarely occurred in the absence of gastric acid, with gastric acid present in 74 of 79 (94%) fifteen minute postprandial intervals with acid reflux. CONCLUSIONS The ability of a meal to buffer gastric acid is poor. Early postprandial oesophageal acid reflux occurs in a substantial proportion of patients. Addition of a weakly acidic or pH neutral meal to ambulatory pH monitoring may unmask early postprandial acid reflux and provide data on gastric acid buffering.

Abstract
BACKGROUND Measurement of oesophageal acid exposure parameters postprandially has been shown to distinguish gastro-oesophageal reflux disease patients from normal individuals. AIMS To calculate the accuracy of postprandial oesophageal integrated acidity in diagnosing gastro-oesophageal reflux disease. METHODS Ambulatory 24-h pH studies of 626 patients were analysed retrospectively. Gastro-oesophageal reflux disease, defined as pH < 4 for > 4.2% of time, was identified in 305 subjects. Postprandial oesophageal integrated acidity was measured for 2 and 3 h after the largest meal peak as determined from gastric pH. Postprandial symptom-associated probability was calculated. RESULTS Gastro-oesophageal reflux disease subjects had a greater postprandial oesophageal integrated acidity than non-gastro-oesophageal reflux disease subjects [median (IQR): 0.57 (0.08-2.66) vs. 0.03 (0.01-0.15) mmol*h/L]. Median postprandial oesophageal integrated acidity did not differ with gender or age in gastro-oesophageal reflux disease and non-gastro-oesophageal reflux disease subjects (P > 0.05 for all). A 3-h postprandial oesophageal integrated acidity value of 0.121 mmol*h/L had a 71.1% sensitivity and 71.7% specificity in diagnosing gastro-oesophageal reflux disease. Gastro-oesophageal reflux disease subjects with symptoms had a higher postprandial oesophageal integrated acidity than those without (P = 0.043), whereas non-gastro-oesophageal reflux disease subjects with and without symptoms did not differ (P = 0.74). The correlation between symptom-associated probability and postprandial oesophageal integrated acidity was poor (gastro-oesophageal reflux disease: r = 0.15; non-gastro-oesophageal reflux disease: r = 0.25). CONCLUSION Postprandial oesophageal integrated acidity provides a robust estimation of oesophageal acid exposure and may predict symptoms in gastro-oesophageal reflux disease patients.

Abstract
The purpose of our study was to determine the frequency, radiographic features, and clinical importance of transient failure of opening of the lower oesophageal sphincter (LOS) on upright double-contrast views of the oesophagus. A computerized search of radiology records identified 16 patients who had transient failure of opening of the LOS on upright views from biphasic oesophagrams or upper gastrointestinal tract examinations using high-density barium but normal opening of the LOS on prone views using low-density barium. The radiographic findings were reviewed and correlated with the clinical and manometric findings. In all cases, barium studies revealed tapered, beaklike narrowing of the distal oesophagus on upright double-contrast views, with a normal-appearing distal oesophagus, normal opening of the LOS, and intact peristalsis on prone single-contrast views. Only seven patients (44%) had dysphagia. Five of these patients had clinical follow-up, and the dysphagia improved or resolved without specific treatment for LOS dysfunction in four. The remaining patient had persistent dysphagia, but this individual had polymyositis as the likely cause for his dysphagia. Manometry revealed incomplete relaxation of the LOS in two patients and normal relaxation in one. Our experience suggests that failure of opening of the LOS may be observed as a transient finding of little clinical importance on upright double-contrast views of the oesophagus using high-density barium, with normal opening of the LOS on prone single-contrast views using low-density barium. It is important to be aware of this finding, so that it is not mistaken for achalasia or other abnormalities of the distal oesophagus.

Abstract
The purpose of our study was to determine the accuracy of double-contrast barium studies and endoscopy for detecting reflux esophagitis, using the endoscopic biopsy findings as the gold standard. A review of radiology, endoscopy, and pathology files showed 37 patients with reflux symptoms who underwent double-contrast barium studies and endoscopy with biopsy specimens from the esophagus. The radiographic images were reviewed in a blinded fashion and correlated with the endoscopic and histologic findings to determine the radiographic and endoscopic accuracies for detecting reflux esophagitis, using the endoscopic biopsy specimens as the gold standard. Double-contrast barium studies and endoscopy had low but comparable accuracies for detecting reflux esophagitis, with sensitivities of 35% and 39%, specificities of 79% and 71%, positive predictive values of 73% and 69%, and negative predictive values of 42% and 41%, respectively. When mucosa granularity was evaluated as an individual sign of esophagitis on double-contrast studies, this finding had a sensitivity of 35%, a specificity of 93%, a positive predictive value of 89%, and a negative predictive value of 46% for detecting reflux esophagitis. Our experience suggests that double-contrast barium studies and endoscopy have limited ability to detect reflux esophagitis, in particular mild esophagitis, when using the histologic findings as the gold standard. When radiographic abnormalities are detected, however, mucosal granularity is the single best sign of reflux esophagitis on double-contrast studies.

Abstract
OBJECTIVE The purpose of this study was to determine the findings of short-segment Barrett's esophagus on double-contrast esophagography. MATERIALS AND METHODS A review of pathology and endoscopy data revealed 142 patients with short-segment Barrett's esophagus, which was defined as columnar epithelium in the distal esophagus extending 3 cm or less above the gastroesophageal junction at endoscopy with histopathologic confirmation of intestinal metaplasia. Twenty of these patients underwent double-contrast esophagography. These 20 patients comprised our study group. The original radiology reports and images were reviewed to determine the findings on double-contrast esophagography. Medical records were also reviewed to determine the clinical findings and treatment. RESULTS Double-contrast esophagrams revealed hiatal hernias in 18 patients (90%), gastroesophageal reflux in 16 (80%), reflux esophagitis in seven (35%), peptic scarring or strictures in 11 (55%), and a reticular mucosal pattern in none. A total of 14 patients (70%) had morphologic findings of reflux disease with esophagitis alone (three patients), peptic scarring or strictures alone (seven patients), or both (four patients), but the remaining six (30%) had hiatal hernias or gastroesophageal reflux as the only radiographic finding. CONCLUSION Double-contrast esophagography revealed morphologic findings of reflux disease with esophagitis, peptic scarring or strictures, or both in 70% of patients with short-segment Barrett's esophagus. Thus, the absence of esophagitis or peptic scarring or strictures on double-contrast esophagography does not exclude the possibility of short-segment Barrett's esophagus.

Abstract
OBJECTIVE The purpose of this study was to determine the clinical and radiographic findings in seven adults with congenital esophageal stenosis. CONCLUSION In young or middle-aged individuals, particularly men with long-standing dysphagia, an upper or mid esophageal stricture with multiple ringlike constrictions is a characteristic appearance of congenital esophageal stenosis on double-contrast esophagography.

Abstract
UNLABELLED The treatment of patients with Barrett's oesophagus is controversial. Debate exists regarding the use and value of high dose acid suppression as the standard of practice. Despite prolonged use of high dose proton pump inhibitors (40 mg omeprazole, 60 mg lansoprazole), most studies have shown no convincing evidence of significant regression of Barrett's length. These studies, however, have used fixed doses of proton pump inhibitors and did not regularly document control of oesophageal acid exposure. AIM To determine whether regression of Barrett's epithelium can be achieved with documented maximal acid suppression. METHODS We have prospectively followed nine patients with Barrett's oesophagus (eight male; mean age 60 years) for more than 1 year. They were all treated using medical therapy with pH monitoring documenting oesophageal acid exposure over 24 h < 1.6% of the time, and with two or more esophagogastroduodenoscopies performed by the same endoscopist. RESULTS Acid control was individually tailored and achieved with proton pump inhibitor b.d. (omeprazole 20 mg or lansoprazole 30 mg) and ranitidine at bedtime (HS) (Ran) if necessary. All nine patients (100%) showed some evidence of regression. All nine patients (100%) showed a decrease in Barrett's length (mean 2 cm, range 1-3 cm). Six out of nine (66.67%) patients showed evidence of squamous islands on the last oesophagogastroduodenoscopy. The mean total distal oesophageal acid exposure was 0.38% (range: 0-1.5%). The mean follow-up of patients was 54 months (range: 13-118 months). CONCLUSIONS Consistent and individually tailored maximal acid suppression documented by pH-metry is achievable and may result in decreased length and development of squamous islands in patients with Barrett's epithelium. This approach should be further evaluated as potentially the preferred medical treatment for these patients.

Abstract
OBJECTIVE Gastroesophageal reflux (GER) is increased in the right compared to the left recumbent position. Esophageal acid exposure is related to the acidity at the cardia, but the effect of body position on the acidity at the cardia has not yet been investigated. We aimed to investigate the mechanisms underlying increased esophageal acid exposure in the right recumbent position. METHODS On 2 separate days a 4-h combined esophageal and lower esophageal sphincter (LES) manometry and pH recording of esophagus, gastric cardia, and corpus was performed in the right and left recumbent position after a high fat meal in 10 healthy subjects. RESULTS In the right recumbent position a prolonged esophageal acid exposure (7.0% vs 2.0%, p < 0.03), a higher incidence of reflux episodes (3.8 vs 0.9/h, p < 0.03), more transient LES relaxations (TLESRs) (6.5 vs 3.2/h, p < 0.03), and higher percentage TLESRs associated with reflux (57.0% vs 22.4% p < 0.03) was recorded than in the left supine position. Acidity at gastric cardia and corpus was not affected by body position. CONCLUSIONS Increased esophageal acid exposure in the right recumbent position relative to the left recumbent position is the result of a higher incidence of GER episodes caused by an increased incidence of TLESRs and higher percentage of TLESRs associated with GER. Body position does not affect the acidity at the gastric cardia and corpus.

Abstract
GERD has emerged as an important medical issue by virtue not only of its high prevalence, but also by the concern that it may predispose to adenocarcinoma of the esophagus. It generally is classified into erosive and nonerosive forms. Nonerosive GERD tends to remain as such in most patients, and treatment is based on symptom relief. In contrast, erosive GERD mandates aggressive lifelong treatment based on its inevitable relapse without appropriate treatment. Two excellent therapies are available for GERD. Proton-pump inhibitors are highly efficacious and have an excellent long-term (> 10 years) safety profile. Laparoscopic fundoplication offers a new and easier method of delivering a standard reliable procedure also with excellent long-term efficacy. The occurrence of Barrett's esophagus among reflux patients has emerged as an important problem mostly because of the rapidly rising incidence of adenocarcinoma of the esophagus in the population. All patients with long-standing reflux symptoms should be screened for Barrett's and subsequently followed regularly with surveillance endoscopy if Barrett's is detected. Although there are no data to show that aggressive medical or surgical treatment alters the malignant potential of this disease, patients need lifelong therapy.

Abstract
OBJECTIVE Congenital esophageal stenosis is thought to be a rare disease confined to infancy and childhood with only a few case reports in adults described. METHODS We report five patients between the ages of 19 and 46 yr who presented with this disorder over a 2-yr period. RESULTS Patients had been labeled with reflux strictures, webs, or as idiopathic in the past. All patients had chronic solid food dysphagia, some since early childhood. The location of the stricture varied, occurring in the mid or proximal esophagus in four, but throughout the esophagus in one. Radiographic and endoscopic appearance was a smooth concentric stricture or multiple rings, sometimes tracheal in appearance. Endosonography was performed in two patients, both of whom had focal circumferential hypoechoic wall thickening with disruption of the normal layer pattern corresponding to the areas of luminal narrowing. All patients dilated had good symptomatic response, with resolution of symptoms up to 6 months in follow-up. CONCLUSIONS We suggest that congenital esophageal stenosis does occur in adults and may be underrecognized. Its endosonographic appearance is described.

Abstract
Esophageal dysmotility occurs in association with GERD; however, the cause of these motility abnormalities is not known. It is also not clear whether injury results from the presence of acid itself, inflammatory change or fibrosisin the esophageal wall. It is also unclear if reversal of these abnormalities takes place, and if so, to what degree. There are, however, a subset of patients who seem to have improvement with effective medical or surgical therapy, parodoxically, the same patients in whom a fundoplication, particularly a complete wrap, would lead to severe postoperative dysphagia secondary to preoperative dysmotility. What does all this mean for the individual patient? It is likely that most will not have any important change in esophageal motility abnormalities with standard medical or surgical therapy. Fundoplication might be safely performed in patients with minimal motility abnormalities, but those with severe abnormalities should be approached with caution. The conservative approach is to perform a partial fundoplication (Toupet) in those with ineffective motility (> 30% low-amplitude or nontransmitted contractions). It is hoped that future investigations will aid in understanding the pathogenesis of these abnormalities and how they can be used more precisely to guide antireflux therapy.
