Abstract
The 4th iteration of the Chicago Classification (CC v4.0) for esophageal motility disorders offers more restrictive criteria for the diagnosis of Ineffective Esophageal Motility (IEM) compared to version 3.0 (CC v3.0). In light of the updated criteria for IEM, we aimed to characterize and compare the patients who retained their IEM diagnosis to those who were reclassified as normal motility, and to evaluate the clinical impact of the newly introduced CC v4.0. We performed a retrospective case-control study. We included all individuals who underwent a high-resolution manometry (HRM) between 2020 and 2021 at two centers. Consecutive studies reported as IEM according to the CC v3.0 were reanalyzed according to the CC v4.0. We compared demographics, clinical, manometry, and pH-monitoring parameters. Out of 452 manometry studies, 154 (34%) met criteria for IEM as per the CC v3.0 (CC v3.0 IEM group). Of those, 39 (25%) studies were reclassified as normal studies according to the CC v4.0 (CC v4.0 normal group), while the remaining 115 studies (25% of the overall cohort) retained an IEM diagnosis (CC v4.0 IEM group). The CC v4.0 normal group had more recovered contractions during solid swallows (p = 0.01), less ineffective swallows (p = 0.04), and lower acid exposure time (p = 0.02) compared to the CC4.0 IEM group. Under CC v4.0 criteria, fewer patients are diagnosed with IEM. Those diagnosed with IEM had worse esophageal function and higher acid burden. Though further studies are needed to confirm these findings, our results indicate that CC v4.0 criteria restrict the IEM diagnosis to a more clinically meaningful population.

Abstract
INTRODUCTION GERD is a common disorder and is characterized by the presence of typical or atypical symptoms. In GERD patients, the presence of mucosal alterations in endoscopy is detected in up to 30% of individuals. The clinical presentation of GERD patients may be complex and their management is challenging, due to the heterogeneous clinical presentation. The present review has been performed searching all relevant articles in this field, over the past years, using PubMed database. AREAS COVERED The diagnosis and management of GERD have been significantly improved in the last years due to the increasing availability of reflux monitoring techniques and the implementation of new procedures in the therapeutic armamentarium. Beside traditional impedance-pH variables, new metrics have been developed, increasing the diagnostic yield of reflux monitoring and better predicting the treatment response. Traditional pharmacological treatments include acid-suppressive-therapy and/or anti-acid. On the other hand, surgical treatment and, more recently, endoscopic procedures represent a promising field in the therapeutic approach. EXPERT OPINION Diagnosis and treatment of GERD still represent a challenging area. However, we believe that an accurate upfront evaluation is, nowadays, necessary in addressing patients with GERD to a more accurate diagnosis as well as to the best treatment options.

Abstract
Background/Aims To evaluate the usefulness of gastroesophageal reflux disease questionnaire (GerdQ) and reflux symptom index (RSI) for diagnosis of gastroesophageal reflux disease (GERD) in patients with suspected laryngopharyngeal reflux (LPR) symptoms (cough, hoarseness, globus, and throat pain). Methods A total of 98 patients with LPR symptoms were incorporated from either gastroenterology or otorhinolaryngology clinic. Patient’s laryngoscopic findings were graded by reflux finding score (RFS), and RFS ≥ 7 was considered as positive LPR. Erosive esophagitis on endoscopy or abnormal results on ambulatory impedance-pH monitoring were used as diagnostic criteria for GERD. Esophageal motor function was evaluated using high-resolution esophageal manometry. Results Ninety-three (94.9%) of the 98 subjects were diagnosed as LPR by RFS, but only 15 (15.3%) had GERD. For GerdQ, the cutoff value of 9 showed the highest area under curve (AUC) to diagnose GERD by receiver operating curve analysis (AUC = 0.565); the sensitivity, specificity, positive predictive value, and negative predictive value were unsatisfactory (50.0%, 70.7%, 22.6%, and 89.2%, respectively.) RSI also showed poor performance in diagnosing GERD; the cutoff value of 25 showed the highest yield (AUC = 0.581); the sensitivity, specificity, positive predictive value, and negative predictive value were 42.9%, 79.3%, 26.1%, and 89.0%, respectively. Ineffective esophageal motility was frequently observed (69 of 98, 70.4%), but there was no difference in esophageal motility parameters between GERD and non-GERD patients. Conclusions In patients with LPR symptoms, significant discrepancies are observed between laryngoscopic diagnosis and GERD. In this population, neither GerdQ nor RSI is useful in diagnosing GERD.

Dysphagia Worsens With Increasing Ineffective Swallows Among Patients With Ineffective Esophageal Motility. J Clin Gastroenterol 2022:00004836-990000000-00045.

Abstract
INTRODUCTION Ineffective esophageal motility (IEM) is the most common motility disorder identified on esophageal high-resolution manometry (HRM), but patients with this finding may be asymptomatic. Therefore, we aimed to identify specific HRM findings predictive of symptoms in IEM. METHODS Adult patients (≥18 y) who underwent HRM between March 2016 and July 2019 were retrospectively evaluated and reclassified according to Chicago Classification 4.0 (CC4.0). Demographic information, HRM parameters, and gastroesophageal reflux disease Health-Related Quality of Life Questionnaire responses were captured among those with normal manometry or IEM. We evaluated the association between heartburn, regurgitation, and dysphagia, with respect to HRM findings including ineffective swallows. RESULTS Of 379 patients, 243 (64.1%) had a normal manometry, 136 (35.9%) were on IEM spectrum, and 73 (19.3%) had conclusive IEM by CC4.0. Mean dysphagia scores were significantly higher in those with conclusive IEM compared with those with normal HRM (2.00 vs. 1.36, P=0.002), as was the percentage of individuals reporting dysphagia affecting daily activities (21.9% vs. 11.4%, P=0.02). Heartburn and regurgitation symptoms did not differ between groups. In a multivariable model of IEM patients, the percentage of ineffective swallows independently predicted a higher dysphagia burden (β regression coefficient: 0.032, P=0.04). CONCLUSIONS Applying the CC4.0 definition for conclusive IEM identifies a group of patients with worse dysphagia symptoms. Within this group, the percentage of ineffective swallows was an independent predictor of dysphagia severity. These findings may help practitioners and patients contextualize the heterogeneous diagnosis of IEM.

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

Abstract
Esophageal hypomotility disorders manifest with abnormal esophageal body contraction vigor, breaks in peristaltic integrity, or failure of peristalsis in the context of normal lower esophageal sphincter relaxation on esophageal high-resolution manometry (HRM). The Chicago Classification version 4.0 recognizes two hypomotility disorders, ineffective esophageal motility (IEM) and absent contractility, while fragmented peristalsis has been incorporated into the IEM definition. Updated criteria for ineffective swallows consist of weak esophageal body contraction vigor measured using distal contractile integral (DCI, 100-450 mmHg·cm·s), transition zone defects >5 cm measured using a 20 mmHg isobaric contour, or failure of peristalsis (DCI < 100 mmHg·cm·s). More than 70% ineffective swallows and/or ≥50% failed swallows are required for a conclusive diagnosis of IEM. When the diagnosis is inconclusive (50%-70% ineffective swallows), supplementary evidence from multiple rapid swallows (absence of contraction reserve), barium radiography (abnormal bolus clearance), or HRM with impedance (abnormal bolus clearance) could support a diagnosis of IEM. Absent contractility requires 100% failed peristalsis, consistent with previous versions of the classification. Consideration needs to be given for the possibility of achalasia in absent contractility with dysphagia despite normal IRP, and alternate complementary tests (including timed upright barium esophagram and functional lumen imaging probe) are recommended to confirm or refute the presence of achalasia. Future research to quantify esophageal bolus retention on stationary HRM with impedance and to understand contraction vigor thresholds that predict bolus clearance will provide further refinement to diagnostic criteria for esophageal hypomotility disorders in future iterations of the Chicago Classification.

Abstract
INTRODUCTION Ineffective esophageal motility (IEM) is a minor motor disorder with potential reflux implications. Contraction reserve, manifested as augmentation of esophageal body contraction after multiple rapid swallows (MRS), may affect esophageal acid exposure time (AET) in IEM. METHODS Esophageal high-resolution manometry (HRM) and ambulatory reflux monitoring studies were reviewed over 2 years to identify patients with normal HRM, IEM (≥50% ineffective swallows), and absent contractility (100% failed swallows). Single swallows and MRS were analyzed using HRM software tools (distal contractile integral, DCI) to determine contraction reserve (mean MRS DCI to mean single swallow DCI ratio >1). Univariate analysis and multivariable regression analyses were performed to determine motor predictors of abnormal AET in the context of contraction reserve. RESULTS Of 191 eligible patients, 57.1% had normal HRM, 37.2% had IEM, and 5.8% had absent contractility. Contraction reserve had no affect on AET in normal HRM. Nonsevere IEM (5-7 ineffective swallows) demonstrated significantly lower proportions with abnormal AET in the presence of contraction reserve (30.4%) compared with severe IEM (8-10 ineffective swallows) (75.0%, P = 0.03). Abnormal AET proportions in nonsevere IEM with contraction reserve (32.7%) resembled normal HRM (33.0%, P = 0.96), whereas that in severe IEM with (46.2%) or without contraction reserve (50.0%) resembled absent contractility (54.5%, P ≥ 0.6). Multivariable analysis demonstrated contraction reserve to be an independent predictor of lower upright AET in nonsevere (odds ratio 0.44, 95% confidence interval 0.23-0.88) but not severe IEM. DISCUSSION Contraction reserve affects esophageal reflux burden in nonsevere IEM. Segregating IEM into severe and nonsevere cohorts has clinical value.

Abstract
Gastroesophageal reflux disease (GERD) is a chronic common disorder for which patients often refer to specialists. In the last decades, numerous studies helped to clarify the pathophysiology and the natural history of this disease. Currently, in the clinical setting, GERD is defined by the presence of symptoms that, when endoscopic investigation is required, permit to distinguish between cases with or without associated esophageal mucosal injuries. These conditions are called erosive reflux disease and non-erosive reflux disease (NERD), respectively. The latter is the most common manifestation of GERD. Symptoms are defined typical, as heartburn and regurgitation, and atypical (also called extra-esophageal), as coughing and/or wheezing, hoarseness, sore throat, otitis media, and dental manifestations. In this context, it is crucial for clinicians to investigate the presence of features of suspected malignancy, as unexplained weight loss, anemia, dysphagia, persistent vomiting, familiar history of cancer, long history of GERD, and beginning of GERD symptoms after the age of 50 years. The presence of these risk factors should induce to perform an endoscopic examination. Particular attention should be given to functional conditions that can mimic GERD, such as functional heartburn and hypersensitive esophagus as well as, more rarely, eosinophilic esophagitis. The former ones have different pathophysiology and this explains the frequent non-response to proton pump inhibitor drugs. This narrative review provides to clinicians a useful and practical overview of the state-of-the-art on advancements in the knowledge of GERD.

Abstract
INTRODUCTION The management of gastro-esophageal reflux disease (GERD) patients is often complex as the clinical presentation is heterogeneous and the mechanisms underlying symptoms are multifactorial. In the past decades, investigations conducted with conventional manometry and, above all, the more accurate high resolution manometry (HRM), helped us in exploring the field of esophageal motility and in understanding the link between motor features and GERD pathogenesis. AREAS COVERED Several studies carried out with conventional manometry and HRM have confirmed a relevant role of esophageal motor function in GERD pathogenesis. In particular, HRM studies have shown a direct correlation between impaired esophageal body motility, disruption of the esophagogastric junction and reflux burden. These findings impact the clinical and therapeutical management of GERD patients. Moreover, HRM findings might be helpful in evaluating patients with proton pump inhibitor (PPI) resistance and inconclusive evidences of GERD. EXPERT OPINION The relationship between esophageal motility and GERD pathogenesis needs to be further evaluated by multicenter outcome studies involving a large number of GERD patients and healthy controls. However, other more promising areas could be progressed.

Abstract
BACKGROUND Gastro-esophageal reflux disease (GERD) can present with typical or atypical or laryngo-pharyngeal reflux (LPR) symptoms. Pulmonary aspiration of gastric refluxate is one of the most serious variants of reflux disease as its complications are difficult to diagnose and treat. The aim of this study was to establish predictors of pulmonary aspiration and LPR symptoms. METHODS Records of 361 consecutive patient from a prospectively populated database were analyzed. Patients were categorized by symptom profile as predominantly LPR or GERD (98 GER and 263 LPR). Presenting symptom profile, pH studies, esophageal manometry and scintigraphy and the relationships were analyzed. RESULTS Severe esophageal dysmotility was significantly more common in the LPR group (p = 0.037). Severe esophageal dysmotility was strongly associated with isotope aspiration in all patients (p = 0.001). Pulmonary aspiration on scintigraphy was present in 24% of patients. Significant correlation was established between total proximal acid on 24-h pH monitoring and isotope aspiration in both groups (p < 0.01). Rising pharyngeal curves on scintigraphy were the strongest predictors of isotope aspiration (p < 0.01). CONCLUSIONS Severe esophageal dysmotility correlates with LPR symptoms and reflux aspiration in LPR and GERD. Abnormal proximal acid score on 24-h pH monitoring associated with pulmonary aspiration in reflux patients. Pharyngeal contamination on scintigraphy was the strongest predictor of pulmonary aspiration.

Abstract
Objectives The role of gastroesophageal reflux disease (GERD) in the aetiology of laryngopharyngeal reflux (LPR) is poorly understood and remains a controversial issue. The 24-hour impedance monitoring has shown promise in the evaluation of LPR but is problematic in pharyngeal recording. We have shown the utility of scintigraphic studies in the detection of LPR and lung aspiration of refluxate. Correlative studies were obtained in patients with a strong history of LPR and severe GERD. Methods A highly selected sequential cohort of patients with a high pre-test probability of LPR/severe GERD who had failed maximal medical therapy were evaluated with 24-hour impedance/pH, manometry and scintigraphic reflux studies. Results The study group comprised 34 patients (15 M, 19 F) with a mean age of 56 years (range: 28-80 years). The majority had LPR symptoms (mainly cough) in 31 and severe GERD in 3. Impedance bolus clearance and pH studies were abnormal in all patients in the upright and supine position. A high rate of non-acid GERD was detected by impedance monitoring. LOS tone and ineffective oesophageal clearance were found in the majority of patients. Scintigraphic studies showed strong correlations with impedance, pH and manometric abnormalities, with 10 patients showing pulmonary aspiration. Conclusion Scintigraphic studies appear to be a good screening test for LPR and pulmonary aspiration as there is direct visualisation of tracer at these sites. Impedance studies highlight the importance of non-acidic reflux and bolus clearance in the causation of cough and may allow the development of a risk profile for pulmonary aspiration of refluxate.

[PMID: 31482661 PMCID: PMC6899806 DOI: 10.1111/nmo.13707] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Revised: 07/15/2019] [Accepted: 08/06/2019] [Indexed: 12/23/2022]
Abstract
BACKGROUND The pathophysiological mechanism(s) of gastroesophageal reflux disease (GERD)-related chronic cough (CC) is unclear. We aimed to determine the mechanism of reflux-induced cough by synchronous monitoring of reflux episodes, esophageal motility, and cough. METHODS Patients with GERD were prospectively enrolled and classified into GERD with CC (GERD-CC) and without CC (GERD) groups. Twenty-four-hour ambulatory pH-impedance-pressure monitoring was performed; the reflux patterns, esophageal motility during prolonged exposure to acid and characteristics of reflux episodes that induced coughing paroxysms were analyzed. KEY RESULTS Thirty-one patients with GERD-CC and 47 with GERD were enrolled; all of whose monitoring results fulfilled the criteria for diagnosis of GERD. Patients with GERD-CC had higher reflux symptom scores, longer exposure to acid, higher DeMeester scores, and more frequent reflux episodes, proximal extent reflux detected by impedance, and higher percentage of strongly acidic reflux than patients in the GERD group (all P < .05). Of 63 reflux-cough episodes identified in the GERD-CC group, 74.6% of distal reflux and 67.0% of proximal reflux episodes were acidic. More patients had low pan-esophageal pressure in primary peristalsis (48.5% vs 11.8%, P = .000) and synchronous contraction in secondary peristalsis during prolonged exposure to acid in the GERD-CC than in the GERD group (63.9% vs 9.1%, P = .000). CONCLUSIONS & INFERENCES Proximal acidic reflux and distal reflux-reflex are jointly associated with reflux-induced cough in patients with GERD. Low pan-esophageal pressure in primary peristalsis and synchronous contraction in secondary peristalsis may play important roles in GERD-associated chronic cough.

Ineffective esophageal motility: Concepts, future directions, and conclusions from the Stanford 2018 symposium. Neurogastroenterol Motil 2019; 31:e13584.

Abstract
BACKGROUND Ineffective esophageal motility (IEM) is a heterogenous minor motility disorder diagnosed when ≥50% ineffective peristaltic sequences (distal contractile integral <450 mm Hg cm s) coexist with normal lower esophageal sphincter relaxation (integrated relaxation pressure < upper limit of normal) on esophageal high-resolution manometry (HRM). Ineffective esophageal motility is not consistently related to disease states or symptoms and may be seen in asymptomatic healthy individuals. PURPOSE A 1-day symposium of esophageal experts reviewed existing literature on IEM, and this review represents the conclusions from the symposium. Severe IEM (>70% ineffective sequences) is associated with higher esophageal reflux burden, particularly while supine, but milder variants do not progress over time or consistently impact quality of life. Ineffective esophageal motility can be further characterized using provocative maneuvers during HRM, especially multiple rapid swallows, where augmentation of smooth muscle contraction defines contraction reserve. The presence of contraction reserve may predict better prognosis, lesser reflux burden and confidence in a standard fundoplication for surgical management of reflux. Other provocative maneuvers (solid swallows, standardized test meal, rapid drink challenge) are useful to characterize bolus transit in IEM. No effective pharmacotherapy exists, and current managements target symptoms and concurrent reflux. Novel testing modalities (baseline and mucosal impedance, functional lumen imaging probe) show promise in elucidating pathophysiology and stratifying IEM phenotypes. Specific prokinetic agents targeting esophageal smooth muscle need to be developed for precision management.

Abstract
Esophageal high resolution manometry (HRM) is the gold standard for assessment of esophageal motor disorders, but motor responses to the standard 5 mL water swallow protocol may not provide precision in defining minor motor disorders. Provocative maneuvers, particularly multiple rapid swallows (MRS), have been used to assess deglutitive inhibition during the repetitive swallows, and the contractile response following the final swallow of the sequence. The augmentation of esophageal smooth muscle contraction following MRS is termed contraction reserve. This is determined as the ratio between esophageal body contraction vigor (distal contractile integral, DCI) following MRS to the mean DCI after single swallows, which is ≥1 in the presence of contraction reserve. Reliable assessment of contraction reserve requires the performance of 3 MRS maneuvers during HRM. Absence of contraction reserve is associated with a higher likelihood of late postfundoplication dysphagia and may correlate with higher esophageal reflux burden on ambulatory reflux monitoring. Esophageal motor responses to abdominal compression, functional lumen imaging probe (FLIP) balloon distension, and pharmacologic testing (using edrophonium and cisapride) may correlate with contraction reserve. Other provocative tests useful during HRM include rapid drink challenge, solid and viscous swallows, and standardized test meals, which are more useful in evaluation of esophageal outflow obstruction and dysphagia syndromes than in identification of contraction reserve. Provocative maneuvers have been recommended as part of routine HRM protocols, and while useful clinical information can be gleaned from these maneuvers, further research is necessary to determine the precise role of provocative testing in clinical esophagology.

High-resolution Manometry Findings During Solid Swallows Correlate With Delayed Reflux Clearance and Acid Exposure Time in Non-erosive Reflux Disease Patients.

Abstract
Background/Aims The role of esophageal motility in determining gastroesophageal reflux disease (GERD) severity has not been completely evaluated. A few studies have investigated high-resolution manometry (HRM) patterns during solid swallows. The present study evaluates the HRM patterns of non-erosive reflux disease (NERD) patients during both liquid and solid swallows and their correlation with the severity of GERD. Methods In 23 NERD patients and 15 healthy volunteers (HVs) HRM was performed during a standard solid meal in a seated position, followed by 24-hour impedance-pH monitoring. Results Of the 31 patients, 10 showed a pathological acid exposure time (AET; NERD patients), 13 a normal pH profile with positive symptom association probability (SAP; reflux hypersensitivity patients), and 8 normal AET and SAP (functional heartburn patients). Mean distal contractile integral and distal latency values, in all patient groups and HVs, were significantly higher during solid swallows. In the group of 10 NERD patients, the number of large breaks of the esophageal peristalsis was 16 out of 100 liquid swallows (16%) and 31 out of 171 solid swallows (18%). Fourteen out of 100 liquid swallows (14%) and 25 out of 171 solid swallows (15%) resulted ineffective. Mean reflux clearing time at multichannel intraluminal impedance-pH was 17.6 ± 3.7 seconds. NERD patients presented, during solid swallows, a significantly higher proportion of large peristaltic breaks and of ineffective swallows than reflux hypersensitivity and functional heartburn patients. Conclusion HRM during solid swallows reveals motor abnormalities, undetected during liquid swallows, which might be involved in delaying reflux and acid clearance in patients with GERD.

Abstract
Clinical history, questionnaire data and response to antisecretory therapy are insufficient to make a conclusive diagnosis of GERD in isolation, but are of value in determining need for further investigation. Conclusive evidence for reflux on oesophageal testing include advanced grade erosive oesophagitis (LA grades C and D), long-segment Barrett's mucosa or peptic strictures on endoscopy or distal oesophageal acid exposure time (AET) >6% on ambulatory pH or pH-impedance monitoring. A normal endoscopy does not exclude GERD, but provides supportive evidence refuting GERD in conjunction with distal AET <4% and <40 reflux episodes on pH-impedance monitoring off proton pump inhibitors. Reflux-symptom association on ambulatory reflux monitoring provides supportive evidence for reflux triggered symptoms, and may predict a better treatment outcome when present. When endoscopy and pH or pH-impedance monitoring are inconclusive, adjunctive evidence from biopsy findings (histopathology scores, dilated intercellular spaces), motor evaluation (hypotensive lower oesophageal sphincter, hiatus hernia and oesophageal body hypomotility on high-resolution manometry) and novel impedance metrics (baseline impedance, postreflux swallow-induced peristaltic wave index) can add confidence for a GERD diagnosis; however, diagnosis cannot be based on these findings alone. An assessment of anatomy, motor function, reflux burden and symptomatic phenotype will therefore help direct management. Future GERD management strategies should focus on defining individual patient phenotypes based on the level of refluxate exposure, mechanism of reflux, efficacy of clearance, underlying anatomy of the oesophagogastric junction and psychometrics defining symptomatic presentations.

Abstract
Background/Aims Evaluation of esophageal clearance by orange juice swallowing could be useful to identify different categories of gastroesophageal reflux disease. We determined whether a juice test at the beginning of esophageal pH monitoring can identify nonerosive reflux disease (NERD) among heartburn patients. Methods Multiple swallows of orange juice (pH 3) were performed at the beginning of esophageal pH monitoring in 71 heartburn patients off acid-suppressive therapy. The area between pH drop below 5 and recovery to 5 was calculated from pH tracings and named Delta5 (mmol·L−1·sec). Fifteen healthy subjects served to determine Delta5 cutoff (95th percentile). Patients were classified as NERD, non-NERD (a mix of reflux hypersensitivity, functional heartburn, and undetermined), and erosive disease depending on acid exposure, reflux symptom analysis, and upper endoscopy. Results Delta5 cutoff in healthy subjects was 251 mmol·L−1·sec. Among 71 patients, 23 had NERD, 26 had non-NERD, and 22 had erosive disease. Compared to non-NERD, Delta5 was higher in both NERD (median [interquartile range]: 316 [213–472] vs 165 [105–225]; P < 0.01) and erosive disease (310 [169–625] vs 165 [105–225]; P < 0.01). An elevated Delta5 (> 251 mmol·L−1·sec) showed sensitivity of 74% and specificity of 81% for identification of NERD. Positive and negative likelihood ratios were 3.84 and 0.32 respectively, whereas test accuracy was 78%. Conclusions A juice test with calculation of Delta5 helps in the identification of true NERD among heartburn patients with endoscopy-negative reflux disease. In these patients, an elevated Delta5 could make prolonged reflux testing unnecessary.

Abstract
BACKGROUND Multiple rapid swallows (MRS) is a provocative test for assessment of contraction reserve, however reproducibility on repetitive MRS is incompletely understood. Our aim was to determine the optimal number of MRS sequences for consistent assessment of contraction reserve. METHODS One hundred and fifty-nine consecutive patients (79 IEM and 80 normal motility) who underwent high-resolution manometers were enrolled. Ten single swallows (SS) and 10 MRS were performed. Gold standard for evaluation of the contraction reserve was the ratio between the mean DCI of 10 MRS and the mean DCI of 10 SS (MRS/SS DCI ratio). Rates of false negatives and false positives were calculated for increasing numbers of MRS sequences, using either mean DCI or the MRS with the highest DCI. KEY RESULTS According to the gold standard, 50 IEM and 50 normal motility patients had contraction reserve. With progressively increasing numbers of MRS sequences, contraction reserve was detected using mean MRS DCI within three and four MRS sequences in IEM and normal motility respectively, whereas two and three MRS sequences were needed using the MRS sequence with the highest DCI. False positives were much higher with highest DCI method compared with mean DCI, (22% vs 9% respectively in IEM; 24% vs 9% in normal motility) when three MRS sequences were considered. CONCLUSIONS & INFERENCES At least three MRS are needed to reliably assess contraction reserve. The mean DCI of the three MRS sequences is the best variable to utilize as evidence of contraction reserve.

Abstract
BACKGROUND Ineffective esophageal motility (IEM) is the most common finding on high-resolution esophageal manometry (HREM). The underlying mechanisms for IEM remain to be fully elucidated. The aim of this study was to determine if utilization of skeletal muscle relaxants is associated with IEM, and with more severe subtypes of the disorder. METHODS Patients with diagnosis of IEM were gender and age matched to patients with normal HREM. Demographic information, symptoms, endoscopic findings, medication usage and medical comorbidities were recorded. Patients with a diagnosis of IEM were divided into subgroups based on mean distal contractile integral (DCI) and percentage of ineffective swallows, and assessed for clinically significant differences among patients with varying severity of underlying IEM. KEY RESULTS A total of 118 patients were included in each group. There were no significant clinical differences between the group of patients with IEM and the group of patients with normal manometry. Within the group of IEM patients, those with mean DCI < 250 mm Hg/s/cm were more likely to be prescribed skeletal muscle relaxants (27.8% vs 11.0%, P = .044), and those using skeletal muscle relaxants had a larger mean percentage of ineffective swallows (81.1% vs 71.5%, P = .029). There were no significant differences across mean DCI subgroups in usage of any other medication, or in any of the demographic variables or disease comorbidities examined in this study. CONCLUSIONS & INFERENCES Use of skeletal muscle relaxants is associated with more severe IEM, which may suggest a causal association between this class of medications and weaker esophageal peristalsis.

Abstract
Objectives: Ineffective esophageal motility (IEM) is characterized by well-defined manometric criteria. However, much variation exists within the diagnosis: Some patients exhibit exactly the required five weak swallows to make the diagnosis. Others show consistently ineffective swallows with total absence of any normal swallow. “We hypothesize” there are two different manometric subtypes of IEM; IEM Alternans (IEM-A) and IEM Persistens (IEM-P). Methods: A total of 231 IEM patients were identified by high-resolution manometry (HRM). IEM defined by distal contractile integral (DCI) <450 mm Hg/s/cm in ≥50% of test swallows. Abnormal reflux study was defined by excess total number of reflux episodes, abnormal esophageal acid exposure, or positive symptom association. Results: A total of 195 (84%) patients had IEM-A and 36 (16%) had IEM-P. A striking gender difference with 34% of IEM-A being males compared to 53% of IEM-P. (P=0.03). Mean age of IEM-P (59.6 years+/−13.1) was greater than IEM-A (55.5 years+/−13.6) (P=0.04). Mean lower esophageal sphincter (LES) resting pressure was significantly lower in IEM-P (20.8 mm Hg+/−1.4) than IEM-A (29 mm Hg+/−1.2) (P=0.002). There was no difference in LES-integrated relaxation pressure (IRP), bolus transit, or manometric presence of hiatal hernia between the two groups. Out of 146, 89 (61%) patients had abnormal reflux study. Esophageal acid exposure in upright position was significantly higher in IEM-P than IEM-A (3.5 vs. 1.7%, P=0.04). Poor gastric acid control on proton pump inhibitor (PPI) was more prevalent among IEM-P patients (58%) than IEM-A (27%) (P=0.007). In subgroup analysis of 41 IEM patients with dysphagia, DCI for liquid swallows was significantly lower in IEM-P (111+/−142 mm Hg/s/cm) compared to IEM-A (421+/−502 mm Hg/s/cm) (P=0.04), lower mean LES resting pressure in IEM-P (16.6+/−9 mm Hg) than IEM-A (31.7+/−18 mm Hg) (P=0.01). Conclusions: There are two distinct manometric IEM subtypes; IEM-P with an older male predominance, more advanced reflux disease, weaker LES, and worse response to PPI; likely a more advanced manifestation than IEM-A. However, the question if there are different etiologies underlying the two subtypes remains to be answered.

Abstract
BACKGROUND Ineffective esophageal motility (IEM) is associated with reflux disease, but its natural history is unclear. We evaluated patients undergoing repeat esophageal high resolution manometry (HRM) for symptomatic presentations after antireflux surgery (ARS) to understand the progression of IEM. METHODS Patients with repeat HRM after ARS were included. Ineffective esophageal motility was diagnosed if ≥5 sequences had distal contractile integral (DCI) <450 mmHg cm s. Augmentation of DCI following multiple rapid swallows (MRS) was assessed. The esophagogastric junction (EGJ) was interrogated using the EGJ contractile integral (EGJ-CI). Esophageal motor function was compared between patients with and without IEM. KEY RESULTS Sixty-eight patients (53.9 ± 1.8 years, 66.2% female) had pre- and post-ARS HRM studies 2.1 ± 0.19 years apart. Esophagogastric junction-CI augmented by a mean of 26.3% following ARS. Four IEM phenotypes were identified: 14.7% had persistent IEM, 8.8% resolved IEM after ARS, 19.1% developed new IEM, and 57.4% had no IEM at any point. Patients with IEM had a lower DCI pre- and post-ARS, lower pre-ARS EGJ CI, and lower pre-ARS-integrated relaxation pressure (p ≤ 0.02 for all comparisons); presenting symptoms and other EGJ metrics were similar (p ≥ 0.08 for all comparisons). The IEM phenotypes could be predicted by MRS DCI response patterns (p = 0.008 across groups); patients with persistent IEM had the least DCI augmentation (p = 0.007 compared to no IEM), while those who resolved IEM had DCI augmentation comparable to no IEM (p = 0.08). CONCLUSIONS & INFERENCES Distinct phenotypes of IEM exist among symptomatic reflux patients following ARS. Provocative testing with MRS may help identify these phenotypes pre-ARS.

Abstract
BACKGROUND & AIMS High-resolution manometry (HRM) expands recognition of minor esophageal motor abnormalities, but the clinical significance of these is unclear. We aimed to determine the outcomes of minor esophageal motor abnormalities. METHODS We reviewed HRM tracings from patients who underwent esophageal manometry at Northwestern Memorial Hospital from July 2004 through October 2005 by using the Chicago classification (version 2.0). We identified 301 patients with normal findings or minor manometric abnormalities (weak peristalsis, hypertensive peristalsis, frequent failed peristalsis, or rapid contractions with normal latency). Ninety-eight patients participated in a phone survey in which they were asked questions from the impact dysphagia questionnaire (mean follow-up period, 6 years 5 months). RESULTS Of 301 patients assessed, 166 had normal findings from HRM, 82 had weak peristalsis, 34 had hypertensive peristalsis, 17 had frequent failed peristalsis, and 2 had rapid contractions with normal latency. The primary indications for HRM of dysphagia (44%) and gastroesophageal reflux disease (63%) were unrelated to manometric findings. There were no endoscopic or videofluoroscopic differences between patients with minor manometric abnormalities. Of 98 patients with follow-up, findings from HRM were normal in 63, weak peristalsis was observed in 23, hypertensive peristalsis was observed in 10, and frequent failed peristalsis was observed in 2. No patients underwent surgical myotomy, pneumatic dilation, or botulinum toxin injection. Use of proton pump inhibitors and rates of fundoplication were similar, regardless of manometric findings. Sixteen patients (16%) had significant dysphagia at follow-up; hypertensive peristalsis was the most likely to be symptomatic. CONCLUSIONS Patients with normal and minor esophageal motor abnormalities report minimal symptoms and have few medical interventions related to esophageal dysfunction during long-term follow-up. Therefore, identification of normal and minor motor function is likely a good prognostic indicator.

Abstract
High-resolution manometry enables the categorization of patients with oesophageal dysphagia caused by oesophageal motility disorders into diagnostic categories according to the Chicago Classification. This Review provides an overview of the literature concerning treatment options for patients with dysphagia associated with achalasia, hypercontractile disorders and hypocontractility disorders of the oesophagus. In achalasia, pharmacotherapy and botulinum toxin are less effective than pneumatic dilation or surgical Heller myotomy, which had comparable efficacy in the largest controlled trial to date. Peroral endoscopic myotomy is a novel therapeutic modality that is currently being evaluated in controlled trials versus pneumatic dilation or surgical myotomy. A variety of medical treatments have been evaluated in hypermotility disorders, but only botulinum toxin injection yielded favourable results in a single controlled trial. Few studies have addressed the treatment of dysphagia in patients with oesophageal hypomotility. A variety of prokinetic agents have been studied, but there is no evidence of clinically relevant efficacy from controlled trials.

Abstract
BACKGROUND Gastroesophageal reflux plays an important role in chronic cough (CC). Whether disturbed esophageal motility contributes to increased esophageal reflux exposure or interferes with swallowed bolus clearance is unclear. This study used high resolution esophageal manometry and impedance (HRIM) together with Chicago Classification, and 24-h impedance pH (MII/pH) to address these questions in patients with CC compared with heartburn (HB). METHODS A retrospective review of 32 patients with CC (mean age 57 [95% CI: 52-62] years) and 32 patients with symptoms of HB (55 [52-62] years) referred for HRIM and MII/pH between September 2012 and September 2013 was undertaken. KEY RESULTS Weak peristalsis with large breaks (WPLBs) was observed in 34% of CC patients compared with only 12% of HB patients (p = 0.027). Pathological acid exposure time (AET) was identified in 81% of CC patients with WPLBs compared with 29% without (p = 0.011). Increased AET was associated with prolonged clearance time of refluxed events (p = 0.006) rather than increased number of events. AET correlated with the percentage of peristaltic events with large breaks in CC (ρ = 0.467, p = 0.007). Similar data were obtained for total bolus (acid and non-acid) exposure time. Only one of the CC patients with WPLBs exhibited complete bolus transit (CBT) on swallowing compared with 81% without WPLBs (p < 0.001). Moreover, the percentage of peristaltic events associated with CBT negatively correlated with the percentage of peristaltic events with large breaks (r = -0.653, p < 0.001) in CC. CONCLUSIONS & INFERENCES One-third of CC patients exhibit WPLBs, which directly impacts on clearance of refluxed events and bolus's swallowed. These observations may have important implications for esophageal-bronchial interaction in CC.

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
BACKGROUND Achalasia is a neurodegenerative disorder of the oesophagus. Alteration of motor activity induced by oesophageal distension has not been explored. OBJECTIVES To investigate this function, using high-resolution Manometry. METHODS This study enrolled 15 healthy subjects, 15 nonobstructive dysphagia (NOD), and 18 achalasia patients successfully treated with pneumatic dilation (six with restored peristalsis). The three groups underwent five rapid (<1 s) intraoesophageal infusions of 20-ml air boluses, followed by eight 5-ml water swallows. RESULTS WHEREAS THE RESPONSE RATE TO WATER SWALLOWS WAS SIMILAR IN THE THREE GROUPS, AIR INFUSION INDUCED A LOWER RESPONSE RATE IN ACHALASIA (MEDIAN, INTERQUARTILE RANGE: 70%, 40-100%) and, to a lesser extent, in NOD patients (100%, 60-100%) than in healthy subjects (100%, 100-100%; p < 0.001 and p = 0.06, respectively). However, the response rate was highly variable in achalasia patients irrespective of presence of peristalsis. Furthermore, the strength of motor response to air infusion when compared to water swallows was diminished in achalasia patients but not in healthy subjects and NOD. CONCLUSIONS Motor response to rapid air infusion was variably impaired in achalasia. The role of this alteration in the long-term outcome deserves evaluation.

Abstract
Multiple water swallows (MWS) stimulates neural inhibition, resulting in abolition of contractions in the esophageal body and complete lower esophageal sphincter relaxation, which is followed by peristalsis and the lower esophageal sphincter contraction. We assessed the relationship between MWS and gastroesophageal reflux in patients with esophageal symptoms and with normal findings by high-resolution manometry (HRM). We retrospectively reviewed the clinical records of patients who underwent HRM and a 24-hour ambulatory impedance-pH study. Correlation between the findings of the impedance-pH study and abnormal MWS responses without motility disorders was evaluated. Independent t-tests were used for statistical analysis. Of 28 patients, 20 (71%) had abnormal MWS responses: four (20%) had abnormal responses during MWS, six (30%) had abnormal responses after MWS, and 10 (50%) had abnormal responses both during and after MWS. Total acid exposure times were significantly longer in patients with abnormal MWS responses than in patients with normal MWS responses. In particular, upright acid exposure time and all reflux percent times were significantly longer in patients with abnormal MWS responses. However, bolus clearance time and longest reflux episode were not different between the two groups. Abnormal MWS responses predicted increased acid exposure times in patients with normal findings of HRM by the Chicago classification.

Abstract
Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophageal motility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from non-erosive reflux disease to erosive reflux disease and Barrett’s esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.

Weak peristalsis with large breaks is associated with higher acid exposure and delayed reflux clearance in the supine position in GERD patients. Am J Gastroenterol 2014; 109:46-51.

Abstract
OBJECTIVES Ineffective esophageal motility is frequently observed in gastroesophageal reflux disease (GERD) patients but its clinical relevance remains controversial. In healthy subjects and in patients with nonobstructive dysphagia, it has been demonstrated, by means of high-resolution manometry (HRM), that long breaks of esophageal peristalsis predict delayed bolus clearance. METHODS HRM and 24-h multichannel impedance-pH (MI-pH) monitoring were performed in 40 GERD patients with no evidence of hiatal hernia. Total bolus clearing time (BCT) in upright and supine position and acid exposure time (AET) were calculated. RESULTS Of the 40 patients, 23 showed a pathological AET and 15 erosive reflux disease (ERD). Patients with a pathological number of large breaks were characterized by a significantly lower BCT value in the supine position and higher AET. In all, 10/15 ERD patients (67%) and 5/25 nonerosive reflux disease patients (20%) were characterized by an abnormal number of small or large breaks (P<0.05). ERD patients were characterized by significantly higher AET and BCT in the supine position. CONCLUSIONS GERD patients with a pathological number of large breaks, assessed by HRM, are characterized by a significantly prolonged reflux clearance in the supine position and higher AET. ERD patients display a higher number of esophageal breaks that might explain the development of erosions.

Abstract
Background/Aims Swallowing of cold liquids decreases amplitude and velocity of peristalsis in healthy subjects, using standard manometry. Patients with achalasia and non obstructive dysphagia may have degeneration of sensory neural pathways, affecting motor response to cooling. To elucidate this point, we used high-resolution manometry. Methods Fifteen healthy subjects, 15 non-obstructive dysphagia and 15 achalasia patients, after pneumatic dilation, were studied. The 3 groups underwent eight 5 mL single swallows, two 20 mL multiple rapid swallows and 50 mL intraesophageal water infusion (1 mL/sec), using both water at room temperature and cold water, in a randomized order. Results In healthy subjects, cold water reduced distal contractile integral in comparison with water at room temperature during single swallows, multiple rapid swallows and intraesophageal infusion (ratio cold/room temperature being 0.67 [95% CI, 0.48-0.85], 0.56 [95% CI, 0.19-0.92] and 0.24 [95% CI, 0.12-0.37], respectively). A similar effect was seen in non-obstructive dysphagia patients (0.68 [95% CI, 0.51-0.84], 0.69 [95% CI, 0.40-0.97] and 0.48 [95% CI, 0.20-0.76], respectively), whereas no changes occurred in achalasia patients (1.06 [95% CI, 0.83-1.29], 1.05 [95% CI, 0.77-1.33] and 1.41 [95% CI, 0.84-2.00], respectively). Conclusions Our data suggest impairment of esophageal reflexes induced by cold water in patients with achalasia, but not in those with non obstructive dysphagia.

Abstract
OBJECTIVE. Ineffective esophageal motility is frequently found in patients with gastroesophageal reflux diseases. Secondary peristalsis contributes to esophageal acid clearance. Mosapride improves gastrointestinal (GI) motility by acting on 5-hydroxytrypatamine4 receptors. The authors aimed to evaluate the effect of mosapride on secondary peristalsis in patients with ineffective esophageal motility. MATERIAL AND METHODS. After recording primary peristalsis baseline, secondary peristalsis was stimulated by slowly and rapidly injecting mid-esophageal air in 18 patients. Two separate experiments were randomly performed with 40 mg oral mosapride or placebo. RESULTS. Mosapride had no effect on the threshold volume of secondary peristalsis during slow air distension (9.8 ± 0.97 vs. 10.2 ± 1.0 mL; p = 0.84), but decreased the threshold volume during rapid air distension (4.1 ± 0.2 vs. 4.6 ± 0.3 mL; p = 0.001). The efficiency of secondary peristalsis during rapid air distension increased with mosapride (70% [40-95%]) compared with placebo (60% [10-85%]; p = 0.0003). Mosapride had no effect on the amplitudes of distal pressure wave of secondary peristalsis during slow (94.3 ± 9 vs. 101.9 ± 9.1 mmHg; p = 0.63) or rapid air distension (89.3 ± 9 vs. 95.2 ± 8.3 mmHg; p = 0.24). CONCLUSIONS. Mosapride improves esophageal sensitivity of secondary peristalsis by abrupt air distension but has limited effect on the motor properties of secondary peristalsis in ineffective esophageal motility patients. Despite its well-known prokinetic effect, mosapride enhances the efficiency of secondary peristalsis in patients with ineffective esophageal motility through augmenting esophageal sensitivity instead of motility.

[DOI: 10.1590/s0004-28032013000200019] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/03/2012] [Accepted: 04/15/2013] [Indexed: 01/10/2023]
Abstract
Context Impairment of esophageal motility is a common finding in patients with gastroesophageal reflux disease (GERD) as reduced lower esophageal sphincter (LES) basal pressure. A very low LES pressure might facilitate the occurrence of more gastroesophageal reflux whereas abnormal esophageal peristalsis may contribute to impaired esophageal clearance after reflux. Objective Evaluate the esophageal motor function of the lower esophageal sphincter and esophageal body in the various forms of gastroesophageal reflux disease. Methods The manometrics records of 268 patients, who had evaluation of the esophageal motility as part of the diagnostic gastroesophageal reflux disease were split into four groups, as follows: 33 patients who had no esophagitis; 92 patients who had erosive esophagitis; 101 patients who had short Barrett's esophagus and 42 patients who had long Barrett's esophagus. Results The group who had long Barrett's esophagus showed smaller mean LES pressure and higher percentage of marked LES hypotonia; in the distal segment of the esophageal body the this group showed higher percentage of marked hypocontractility of the distal segment (<30 mm Hg); this same group showed higher percentage of esophageal motility disorders. Conclusions The most intense esophageal motility disorders and lower pressure of lower esophageal sphincter were noted in the group with long Barrett's esophagus. Those with reflux esophagitis and short Barrett's esophagus had esophageal motility impairment, intermediate among patients with esophagitis and long Barrett's esophagus. Patients with typical symptoms of gastroesophageal reflux but without esophagitis by endoscopy study showed no impairment of esophageal motility.

Abstract
BACKGROUND It was recently shown that GERD patients have lower impedance baseline (IB) values than healthy controls and, that the esophageal acid exposure time (AET) correlates with IB levels. GOALS To explore the sensitivity of IB measurements in NERD patients, responders and non-responders to PPIs, when compared with pH-impedance (MII-pH) variables, and to evaluate whether this variable could represent a marker of GERD symptoms. Reproducibility and inter-observer agreement of IB measurement were also assessed. Study. MII-pH tracings from 44 NERD responders and 22 non-responders were analysed. Ten healthy volunteers underwent the same protocol. IB values were measured at the distal and proximal esophagus. IB was also analysed in a subgroup of patients and in controls with two methods and by two blinded operators. RESULTS Mean IB values at the distal esophagus were significantly lower in NERD patients than in controls. IB values did not differ between responders and non-responders. Of the 8 responders with negative AET and symptom association probability (SAP), 3 (37.5%) showed IB values lower than controls. IB values in responders with positive and negative SAP were similar (1832 (1596-2068) Ω vs 1667 (1361-1973) Ω, p: n.s.). No differences were found between the IB values measured with the two methods and the inter-observer agreement was good. CONCLUSIONS IB is a promising and easy to calculate MII-pH variable and appears to increase the sensitivity of MII-pH monitoring. IB values cannot predict PPI response and are not associated with reflux perception in NERD patients.

Abstract
The development of the high-resolution esophageal manometry (HRM) and the Chicago classification have improved the diagnosis and management of esophageal motility disorders. However, some conditions have yet to be addressed by this classification. This review describes findings in HRM which are not included in the current Chicago classification based on the experience in our center. This includes the analysis of the upper esophageal sphincter, proximal esophagus, longitudinal muscle contraction, disorders related to gastroesophageal reflux disease and respiratory symptoms. The utility of provocative tests and the use of HRM in the evaluation of rumination syndrome and post-surgical patients will also be discussed. We believe that characterization of the manometric findings in these areas will eventually lead to incorporation of new criteria into the existing classification.

Abstract
BACKGROUND AND AIM Ineffective oesophageal motility (IOM) often occurs in patients with gastro-oesophageal reflux disease. We aimed to examine the hypothesis of whether the presence of IOM differs between patients with gastro-oesophageal reflux disease with different symptom profiles. METHODS Eligible patients were subclassified according to their predominant symptom of heartburn (HB) or acid regurgitation (AR). All patients underwent combined multichannel intraluminal impedance and oesophageal manometry. IOM was further graded according to the presence of oesophageal transit abnormalities. RESULTS Fourteen healthy individuals, 16 HB patients and 24 AR patients participated in this study. The percentage of swallows with complete bolus transit was lower in AR than in HB patients during liquid and viscous swallowing (P<0.05). Abnormal bolus transit occurred more frequently in AR patients than in HB patients with liquid swallows (P<0.001) and viscous swallows (P<0.05). IOM occurred more frequently in AR patients than in HB patients (42.7 vs. 12.5%, P=0.049). In patients with IOM, severe functional abnormality was more frequently found in AR patients than in HB patients (P<0.05). CONCLUSION This study suggests a potential link between oesophageal body dysfunction and individual reflux symptom. Patients with a predominant symptom of AR are characterized by greater IOM and defective bolus clearance.

Abstract
BACKGROUND The link between diabetes mellitus and gastroesophageal reflux disease (GERD) is controversial. We assessed the relationship between glycemic control (GC) and GERD in morbidly obese patients. METHODS Consecutive patients with morbid obesity (n = 86) underwent manometry, pH-metry, endoscopy, and contrasted X-ray after responding to a GERD questionnaire and dosing fasting plasma glucose (FPG) and glycated hemoglobin (HbA1c). Patients with poor GC (HbA1c, 6.1-10% and FPG < 140 mg/dl) and those with very poor GC (HbA1c > 10% or FPG > 140 mg/dl) were compared. RESULTS There were 63 patients with poor GC and 17 with very poor GC. Compared to patients with very poor GC, patients with poor GC showed higher heartburn scores [8 (0-12) vs. 0 (0-4); P = 0.003]; higher total esophageal acid exposure [5.2% (2.5-10.5%) vs. 2.3% (0.8-7.5%); P = 0.041]; lower distal esophageal amplitude (105 ± 38 vs. 134 ± 63 mmHg; P = 0.019); higher expiratory gastroesophageal pressure gradient (GEPG, 7 ± 3.4 vs. 5.2 ± 3 mmHg; P = 0.050); lower ventilatory gradient (inspiratory-expiratory GEPG, 10.9 ± 3.8 vs. 13.6 ± 4.1 mmHg; P = 0.012); lower waist-to-hip ratio (0.95 vs. 1; P = 0.040); and more hiatal hernia (38% vs. 6%; P = 0.016). CONCLUSIONS This study suggests an inverse relation between glycemic control and GERD in morbidly obese patients. This can be partially explained by a lower frequency of hiatal hernia in patients with very poor glycemic control.

Abstract
Manometric location of the lower esophageal sphincter (LES) has been mandatory before esophageal pH monitoring, despite costs and discomfort related with esophageal manometry. The aims of the study were: (i) to map the pH of the gastroesophageal junction (GEJ) to determine a pH turning point (PTP) and its relation with LES; and (ii) to test the feasibility of this technique to orientate esophageal pH monitoring. We studied 310 adult patients who underwent esophageal manometry and pH monitoring off acid-suppressive therapy. GEJ pH mapping was carried out by step-pulling the pH sensor from 5 cm below to 5 cm above LES, and a PTP was determined when pH changed from below to above 4, in centimeters from the nostril. Thirty-six patients referred only for pH monitoring were studied with pH sensor placed at 5 cm above the PTP. Out of 310 patients, a PTP was found in 293 (94.5%): inside LES in 86.3%, into the stomach in 8.2% and in the esophageal body in 5.5% of patients. The median distance between PTP and place where pH sensor monitored reflux was 8 cm. Among 36 patients who performed pH monitoring without LES manometry, there was no gastric monitoring during reflux testing. In adult patients investigated off acid suppressive therapy, GEJ pH mapping with reflux monitoring 5 cm above the PTP can be an alternative technique to perform esophageal pH monitoring when LES manometry is not available. Additional studies are needed before the widespread use of GEJ pH mapping in the clinical practice.

Abstract
Background/Aims Impedance-pH monitoring allows detailed characterization of gastroesophageal reflux and esophageal activity associated with reflux. We assessed the characteristics of nocturnal reflux and esophageal activity preceding and following reflux. Methods Impedance-pH tracings from 11 healthy subjects and 76 patients with gastroesophageal reflux disease off acid-suppressive therapy were analyzed. Characteristics of nocturnal supine reflux, time distribution and esophageal activity seen on impedance at 2 minute intervals preceding and following reflux were described. Results Patients had more nocturnal reflux events than healthy subjects (8 [4-12] vs 2 [1-5], P = 0.002), with lower proportion of weakly acidic reflux (57% [35-78] vs 80% [60-100], P = 0.044). Nocturnal reflux was mainly liquid (80%) and reached the proximal esophagus more often in patients (6% vs 0%, P = 0.047). Acid reflux predominated in the first 2 hours (66%) and weakly acidic reflux in the last 3 hours (70%) of the night. Most nocturnal reflux was preceded by aboral flows and cleared by short lasting volume clearance. In patients, prolonged chemical clearance was associated with less esophageal activity. Conclusions Nocturnal weakly acidic reflux is as common as acid reflux in patients with gastroesophageal reflux disease, and predominates later in the night. Impedance-pH can predict prolonged chemical clearance after nocturnal acid reflux.

Abstract
Abstract
Background
Laparoscopic Nissen fundoplication is the most frequently performed operation for gastro-oesophageal reflux disease (GORD). Studies on predictors of subjective outcome of fundoplication have yielded inconsistent results. This study identified predictors of objective reflux control after Nissen fundoplication.
Methods
This was a retrospective analysis of prospectively collected data from patients who underwent Nissen fundoplication for proton pump inhibitor-refractory GORD with pathological acid exposure in a single centre between 1997 and 2005. The predictive value of demographics, endoscopic hiatal hernia size, oesophagitis, lower oesophageal sphincter pressure, distal oesophageal contraction amplitude, percentage of peristaltic contractions and acid exposure was determined. Endpoints were recurrent pathological acid exposure on 24-h pH monitoring at 6 months and surgical reintervention for recurrent GORD up to 6 years.
Results
Of 177 patients, 22 had recurrent pathological acid exposure at 6 months for which 11 had surgery within 6 years. Only low percentage of peristaltic contractions (odds ratio (OR) 0·97, 95 per cent confidence interval 0·95 to 0·99; P = 0·004) and high supine acid exposure (OR 1·03, 1·00 to 1·07; P = 0·025) were independent predictors of recurrent pathological acid exposure. The absolute risk of recurrent exposure was 45·5 per cent in patients with both predictors. High supine acid exposure was also an independent predictor of surgical reintervention (OR 1·05, 1·01 to 1·08; P = 0·006).
Conclusion
Nissen fundoplication should not necessarily be withheld from patients with poor oesophageal peristalsis or excessive supine acid exposure. As about half of patients with both variables experience recurrent pathological acid exposure after primary Nissen fundoplication, surgery should be restricted in this group.

Abstract
The prevalence of gastro-oesophageal reflux disease (GORD) has been increasing worldwide. This increase is likely associated with the increased prevalence of obesity, the ageing of the population and the decreased prevalence of Helicobacter pylori (Hp) infection. These different environmental factors interact with GORD pathogenesis in a potentially negative way. Oesophago-gastric junction (OGJ) competence, oesophageal clearance mechanisms and reflux causticity are involved in GORD pathophysiology. Obesity alters GORD pathogenesis by disrupting the OGJ and increasing intragastric pressure. Additionally, the number of transient lower oesophageal sphincter relaxations is potentially increased in obese patients. The potential effect of obesity on oesophageal peristalsis and the implication of impaired oesophageal clearance in GORD pathogenesis are still to establish. Ageing also plays an important role in GORD pathogenesis by decreasing lower oesophageal sphincter pressure and impairing oesophageal clearance. However a link between these abnormalities and an increased acid oesophageal exposure has not yet been demonstrated in the elderly. The role of H. pylori and its eradication remain controversial. The type of Hp gastritis may explain the controversial effect. Hp with antral predominant gastritis is responsible for an increased gastric acid secretion and thus promotes GORD. On the opposite spectrum, Hp with diffuse gastritis induces a gastric atrophy and in this particular case, the Hp eradication may restore acid secretion and lead to a more caustic refluxate in patients with predisposing conditions for GORD. The association of GORD and the type of Hp gastritis remains to be confirmed.

Abstract
Delayed gastric emptying in a variable proportion of patients with gastro-oesophageal reflux disease has been observed in most series, however a relationship between delayed gastric emptying and increased gastro-oesophageal reflux has not been convincingly demonstrated. Enhanced postprandial accommodation and delayed emptying of the proximal stomach have been described, but some controversy exists. Impaired primary peristalsis is often present especially in patients with oesophagitis and its prevalence increases with increasing severity of inflammatory mucosal lesions. Patients with gastro-oesophageal reflux disease often have defective triggering of secondary peristalsis independently of presence of oesophagitis. It is presently unclear if impaired oesophageal motility is a primary defect or an irreversible consequence of inflammation. Attempts at pharmacological improvement of impaired oesophageal motility have been so far disappointing. Patients with partially preserved neuromuscular structures need to be identified in order to select them for new prokinetic therapy.

Abstract
Multiple rapid swallowing (MRS) stimulates neural inhibition resulting in abolition of contractions in the oesophageal body (OB) and complete lower oesophageal sphincter (LOS) relaxation which is followed by peristalsis and LOS contraction. The aim of this study was to evaluate the yield of MRS to detect abnormalities in inhibitory or excitatory oesophageal mechanisms in patients with oesophageal symptoms and either normal standard manometry or ineffective oesophageal motility (IOM). MRS (five water swallows, 2 mL, separated by 2-3 s) was evaluated in 23 healthy subjects, 109 symptomatic patients with normal standard sleeve manometry and in 48 patients with IOM. Healthy subjects had complete inhibition of OB motility during MRS and a strong motor response after MRS, i.e. amplitude of OB contractions in the oesophageal body and LOS tone being higher than after single swallows. Almost 70% of patients with oesophageal symptoms and normal manometry had abnormal MRS, mainly consistent on inability to increase amplitude of OB contractions after MRS. Nearly, half of the patients with IOM were able to normalize OB contractions after MRS. MRS is a simple complementary test that can be added to standard oesophageal manometry. Two-thirds of patients with normal manometry show abnormal MRS that could potentially underlie their symptoms. A normal response to MRS in patients with severe IOM might be used to predict response to prokinetic treatment.
