[PMID: 39139634 PMCID: PMC11319146 DOI: 10.3389/fphar.2024.1393526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Accepted: 07/18/2024] [Indexed: 08/15/2024] Open
Abstract
Background Refractory gastroesophageal reflux disease (refractory GERD) is a heterogeneous disease characterized by unresponsiveness or poor efficacy to proton-pump inhibitors (PPIs). This chronic disorder substantially weakens patients' mental wellbeing and quality of life, increasing the financial burden on society. Multiple articles have been reported in this area. However, literature involving scientometric analysis of refractory GERD is absent. Therefore, it is necessary to understand the evolution of research themes and the main hotspots of refractory GERD through bibliometric methods. Methods All documents related to refractory GERD based on the WOS Core Collection from January 2000 to November 2023 were selected for analysis. Citespace V 6.1 R6, VOSviewer V 1.6.20, and Scimago Graphica V 1.0.38 were used to perform bibliometric analysis. Results We collected a total of 241 research articles from 36 countries and 322 institutions, contributed by over 1,000 authors. Over the last 20 years, the number of articles in this field has increased year by year, and since 2011, the number of publications has increased dramatically, with 85.89% of the papers. These countries are led by the United States and Japan. GUT had the highest number of citations and DIGESTION had the highest number of publications. Research on standardized diagnosis and management, mechanisms, novel monitoring methods, and innovative drugs and procedures for refractory GERD are the main topics and hotspots in this field. This study also found that neuroimmune interaction is closely related to refractory GERD, which may be a new direction for future mechanism research. Conclusion Our study is the first bibliometric analysis of the global literature on refractory GERD. This research provides valuable insights for researchers, enabling them to quickly understand the research frontier and hot topics of this field.

Abstract
BACKGROUND Epidemiological studies in achalasia and its clinical management in Australia are limited. AIMS To determine the prevalence and trends in incidence rates and describe the types of treatment stratified by subtypes of achalasia. METHODS A retrospective observational study was conducted at a single site that offers a state-wide high-resolution manometry (HRM) service in Western Australia (WA). Patients (aged ≥ 18 years) newly diagnosed with achalasia based on HRM findings between 2012 and 2021 were extracted from the HRM database. The crude incidence rate and age-standardised incidence rate (ASIR) along with the 2021-point prevalence were calculated. Trends were assessed by the Kendall τb test. The patients' initial and subsequent treatment modalities were described. RESULTS A total of 296 new cases were identified, and the median age at diagnosis was 56 years. The patient's median age, sex and year of the first treatment did not vary significantly with the subtypes. The lowest and highest ASIR (cases/100 000 person-years) were 0.8 in 2012 and 2.1 in 2021, respectively. Only type 2 achalasia showed a significant increasing trend (P = 0.009). The 2021-point prevalence was 16.9 cases/100 000 people and increased with age. Pneumatic balloon dilatation (PBD) was the most common treatment for types 1 and 2, while laparoscopic Heller myotomy was most common for type 3. Peroral endoscopic myotomy (POEM) has become common in the past 5 years. CONCLUSION The ASIR of type 2 achalasia significantly increased in WA. PBD was most commonly performed, although peroral endoscopic myotomy has recently increased as a preferred treatment option.

Abstract
The concept of third space endoscopy first described in 2007, was adapted and performed in humans in 2010 by Inoue et al. in a group of patients with esophageal achalasia (EA). Since then, esophageal endoscopic myotomy (E-POEM), has been performed in more than 10,000 patients worldwide up to now. Safety and efficacy have been confirmed at early, mid and long-term evaluations, in different gastrointestinal diseases including achalasia, refractory gastroparesis, and other esophageal motility disorders (EMD). Nowadays, this treatment has shown to be not only an excellent option, but also with its excellent outcomes, the first option in certain clinical scenarios such as type III achalasia. Thus, the minimal invasive nature of POEM gives us multiple advantages compared with the classical treatments that includes pneumatic dilation (PD) and laparoscopic Heller myotomy (LHM), including not only clinical aspects but also economical. High resolution manometry (HRM) has substantially redefined the actual approach of esophageal motility disorders with the major changes in instrumental use, diagnostic algorithms, and therapeutics. The previous Chicago's classification V 3.0 clearly improved our knowledge about pathophysiology of spastic esophageal motor disorders, however, with its recent update (Chicago V 4.0), multiple changes in diagnosis and treatment are expected. In the present article, we aimed to review and analyze the most important aspects about the results of E-POEM in the management of EMD according to the view of the new Chicago's classification V 4.0.

Abstract
Background/Aims Intrabolus pressures are important for esophageal bolus transport and may detect obstructed bolus flow. This study measured the effect esophageal outflow obstruction experimentally induce by a leg-lift protocol. Methods Twenty-five gastroesophageal reflux disease patients referred for esophageal manometry and a normal motility diagnosis were included. Supine liquid swallows were tested. Leg-lift protocol generated esophageal outflow obstruction by increasing abdominal pressure. Esophageal pressure topography and intrabolus pressure metrics were calculated. These included, (1) mid-domain bolus distension pressure during esophageal emptying (DPE, mmHg) and (2) ramp pressure (mmHg/sec), generated by compression of the bolus between the peristaltic contraction and esophagogastric junction (EGJ). Results EGJ relaxation pressure was increased by leg-lift from 13 (11-17) to 19 (14-30) mmHg (P < 0.005) and distal contractile integral also increased from 1077 (883-1349) to 1620 (1268-2072) mmHg∙cm∙sec (P < 0.001) as a physiological response to obstruction. All bolus pressures were increased by leg lift; DPE increased from 17 (15-20) to 27 (19-32) mmHg (P < 0.001), and ramp pressure increased from 3 (1-4) to 5 (2-9) mmHg/sec (P < 0.05). Conclusion Measuring pressures within the intrabolus domain can quantify changes related to obstruction to outflow and may serve as adjunct measures for confirming a diagnosis EGJ outflow obstruction.

Abstract
Objective To explore the correlation between changes in esophageal pressure and psychological status in patients with globus sensation. Methods A total of 40 patients with globus sensation who attended Wenzhou People’s Hospital between August 2020 and February 2021 were divided into two groups based on the results of esophageal manometry: a high-pressure group and a non-high-pressure group. The duration of disease, clinical symptom score, and self-rating anxiety scale (SAS) were compared between the two groups to determine the relationship between changes in esophageal pressure and psychological status. Results All the patients before treatment were divided into a high-pressure group (n = 14) and a non-high-pressure group (n = 26) according to whether the resting pressure of the upper esophageal sphincter (UES) was greater than 104 mmHg. The differences between the high-pressure group and non-high-pressure group in duration of disease, clinical symptom score, and SAS were statistically significant (all P < 0.05). Anxiety was present in 12 patients in the high-pressure group and two patients in the non-high-pressure group. The difference between the the high-pressure group and non-high-pressure group in the incidence of anxiety was statistically significant (χ2 = 21.04 and P < 0.001). Pearson correlation analysis of the association between esophageal pressure and anxiety resulted in R = 0.74 and P < 0.001. Conclusion Patients with globus sensation who develop anxiety were more likely to have high pressure in the upper esophageal sphincter.

Abstract
The cause of eosinophilic esophagitis (EoE) is not well understood. Most patients with EoE have allergic disorders. Here, we describe a patient with gastroesophageal reflux and EoE with dysphagia, substernal discomfort and retrosternal pain. Based on symptomatology consistent with gastroesophageal reflux disease (GERD), treatment started with proton pump inhibitors (PPIs) but no effect was observed. Next, the patient underwent esophagogastroduodenoscopy and multiple biopsies were acquired from the lower and upper esophagus. Cortisone treatment was given and high-resolution manometry was performed before and after treatment. The results suggested that esophageal motility improved after cortisone therapy together with improvements in the clinical and histological pictures.

Abstract
BACKGROUND Cricopharyngeal botulinum toxin (BTX) injection is one of the treatments for neurogenic cricopharyngeal dysfunction (CPD). We conducted this prospective study to investigate the effect and safety of BTX injection for neurogenic CPD with a novel guidance. METHODS Twenty-one patients with neurogenic CPD whose symptoms did not reduce after conventional swallowing therapy were included in this study. The impact of BTX injection on the swallowing function of the patients was evaluated. KEY RESULTS After the injection, the Functional Oral Intake Scale (FOIS) score increased in 17 of 21 patients (80.9%), which ranged from 1 to 3 (P < 0.001). Moreover, there was a significant reduction in the UES opening impairment (P < 0.01), UES residual pressure (P < 0.05), duration of UES relaxation, penetration-aspiration scale score (P < 0.05), secretion (P < 0.05), vallecular residue (P < 0.01), and left (P < 0.05) and right (P < 0.05) pyriform sinus residue. With at least 6 months of follow-up, we found that FOIS continued to increase in patients who showed improvement after the injection (i.e., FOIS 5-7 points), while it remained unchanged in patients without improvement after the injection. There were no side effects reported in this study. CONCLUSION & INFERENCES BTX injection into the cricopharyngeal muscle guided by ultrasound, catheter balloon, and electromyography possibly has a long-lasting effect that can effectively and safely improve the swallowing function of patients with neurogenic CPD.

Abstract
Background and study aims Due to demographic transition, neurogenic dysphagia has become an increasingly recognized problem. Patients suffering from dysphagia often get caught between different clinical disciplines. In this study, we implemented a defined examination protocol for evaluating the whole swallowing process by functional endoscopy. Special focus was put on the esophageal phase of swallowing. Patients and methods This prospective observational multidisciplinary study evaluated 31 consecutive patients with suspected neurogenic dysphagia by transnasal access applying an ultrathin video endoscope. Thirty-one patients with gastroesophageal reflux symptoms were used as a control group. We applied a modified approach including standardized endoscopic positions to compare our findings with fiberoptic endoscopic evaluation of swallowing and high-resolution manometry. The primary outcome measure was feasibility of functional endoscopy. Secondary outcome measures were adverse events (AEs), tolerability, and pathologic endoscopic findings. Results Functional endoscopy was successfully performed in all patients. No AEs were recorded. A variety of disorders were documented by functional endoscopy: incomplete or delayed closure of the upper esophageal sphincter in retroflex view, clearance disturbance of tubular esophagus, esophageal hyperperistalsis, and hypomotility. Analysis of results obtained with the diagnostic tools showed some discrepancies. Conclusions By interdisciplinary cooperation with additional assessment of the esophageal phase of deglutition using the innovative method of functional endoscopy, the diagnosis of neurogenic disorders including dysphagia may be significantly improved, leading to a better clinical understanding of complex dysfunctional patterns. To the best of our knowledge, this is the first study to show that a retroflex view of the ultrathin video endoscope within the esophagus can be safely performed. [NCT01995929].

Abstract
Background: High resolution manometry (HRM), has been recently introduced in clinical practice to detect esophageal intraluminal pressure and esophageal motor function. We evaluated the feasibility and usefulness of intraoperative esophageal HRM during antireflux laparoscopic procedures in pediatric cases with neurological impairment (NI) or esophageal atresia (EA). Methods: From January to November 2019, seven children (5 NI, 2 EA) with gastroesophageal reflux (GER) were enrolled. Data on intraoperative pressure changes of the esophagogastric junction (EGJ) and postoperative follow-up data were collected. Results: Average preoperative LES pressures were not significantly different from postoperative pressures. A sliding hernia was detected in all patients as evidenced by EGJ double peak pressures. Hernia correction after esophageal traction was complete in 71.4% of the patients, and residual hernia (<2 cm) was detected in 28.6%. Postoperative EGJ pressures were higher compared to preoperative sphincteric pressures (p < 0.001); in NI patients, higher postoperative values were noted compared to EA (p = 0.05). No sliding hernia and/or GER relapses were recorded. Two patients reported dysphagia postoperatively. Conclusions: Intraoperative HRM may optimize esophageal pressure changes during laparoscopic fundoplication. Further studies are needed to confirm the usefulness of a tailored surgical approach to reduce postoperative complications.

Abstract
Characterization of high-amplitude propagating pressure waves (HAPWs or HAPCs) plays a key role in diagnosis of colon dysmotility using any type of colonic manometry. With the introduction of high-resolution manometry, more insight is gained into this most prominent propulsive motor pattern. Here, we use a water-perfused catheter with 84 sensors with intervals between measuring points of 1 cm throughout the colon, for 6-8 h, in 19 healthy subjects. The catheter contained a balloon to evoke distention. We explored as stimuli a meal, balloon distention, oral prucalopride, and bisacodyl injection, with a goal to optimally evoke HAPWs. We developed a quantitative measure of HAPW activity, the "HAPW Index." Our protocol elicited 290 HAPWs. 21% of HAPWs were confined to the proximal colon with an average amplitude of 75.3 ± 3.3 mmHg and an average HAPW Index of 440 ± 58 mmHg·m·s. 29% of HAPWs started in the proximal colon and ended in the transverse or descending colon, with an average amplitude of 87.9 ± 3.1 mmHg and an average HAPW Index of 3,344 ± 356 mmHg·m·s. Forty-nine percent of HAPWs started and ended in the transverse or descending colon with an average amplitude of 109.3 ± 3.3 mmHg and an average HAPW Index of 2,071 ± 195 mmHg·m·s. HAPWs with and without simultaneous pressure waves (SPWs) initiated the colo-anal reflex, often abolishing 100% of anal sphincter pressure. Rectal bisacodyl and proximal balloon distention were the most optimal stimuli to evoke HAPWs. These measures now allow for a confident diagnosis of abnormal motility in patients with colonic motor dysfunction.NEW & NOTEWORTHY High-amplitude propagating pressure waves (HAPWs) were characterized using 84 sensors throughout the entire colon in healthy subjects, taking note of site of origin, site of termination, amplitude, and velocity, and to identify optimal stimuli to evoke HAPWs. Three categories of HAPWs were identified, including the associated colo-anal reflex. Proximal balloon distention and rectal bisacodyl were recognized as reliable stimuli for evoking HAPWs, and a HAPW Index was devised to quantify this essential colonic motor pattern.

Abstract
Achalasia is a rare esophageal motility disorder. Much of the literature is based on the adult population. In adults, guidance of therapeutic approach by manometric findings has led to improvement in patient outcome. Promising results have been achieved with novel therapies such as PerOral Endoscopic Myotomy (POEM). Areas covered: In this review, we provide an overview of the novel diagnostic and therapeutic tools for achalasia management and in what way they will relate to the future management of pediatric achalasia. We performed a PubMed and EMBASE search of English literature on achalasia using the keywords 'children', 'achalasia', 'pneumatic dilation', 'myotomy' and 'POEM'. Cohort studies < 10 cases and studies describing patients ≥ 20 years were excluded. Data regarding patient characteristics, treatment outcome and adverse events were extracted and presented descriptively, or pooled when possible. Expert commentary: Available data report that pneumatic dilation and laparoscopic Heller's myotomy are effective in children, with certain studies suggesting lower success rates in pneumatic dilation. POEM is increasingly used in the pediatric setting with promising short-term results. Gastro-esophageal reflux disease (GERD) may occur post-achalasia intervention due to disruption of the LES and therefore requires diligent follow-up, especially in children treated with POEM.

Abstract
BACKGROUND Abdominal compression has been implemented as a provocative maneuver in high-resolution impedance manometry (HRIM) to "challenge" normal esophageal physiology with the aim of revealing abnormal motor patterns which may explain symptoms. In this study, we measured the effects of abdominal compression on esophageal functioning utilizing novel pressure-impedance parameters and attempted to identify differences between healthy controls and globus patients. METHODS Twenty-two healthy volunteers (aged 23-32 years, 41% female) and 22 globus patients (aged 23-72 years, 68% female) were evaluated with HRIM using a 3.2-mm water perfused manometric and impedance catheter. All participants received 10 × 5 mL liquid swallows; healthy controls also received 10 × 5 mL liquid swallows with abdominal compression created using an inflatable cuff. All swallows were analyzed to assess esophageal pressure topography (EPT) and pressure-flow metrics, indicative of distension pressure, flow timing and bolus clearance were derived. KEY RESULTS The effect of abdominal compression was shown as a greater contractile vigor of the distal esophagus by EPT and higher distension pressure based on pressure-flow metrics. Age and body mass index also increased contractile vigor and distension pressure. Globus patients were similar to controls. CONCLUSIONS AND INTERFERENCES Intrabolus pressure and contractile vigor are indicative of the physiological modulation of bolus transport mechanisms. Provocative testing by abdominal compression induces changes in these esophageal bolus dynamics.

Abstract
OBJECTIVE The anatomy of esophagogastric junction (EGJ) serves as the anti-reflux barrier. The gastroesophageal flap valve (GEFV) is a component of EGJ. The aim of the current study was to assess its correlation with the esophageal acid exposure and the impact on anti-reflux barrier function by using the metrics of EGJ contraction. METHODS Eighty three patients with typical GERD symptoms were included in the study. Upper endoscopy, high-resolution manometry (HRM) and 24 h multichannel intraluminal impedance-pH (MII-pH) monitoring were performed in all patients. GEFV was determined as four grades during endoscopic examination based on the Hill classification. The esophageal pressure topography (EPT) metrics defined in the updated Chicago Classification were measured by HRM, including integrated relaxation pressure (IRP), EGJ contractile index (EGJ-CI),expiratory EGJ pressure(EGJP-exp) and inspiratory EGJ pressure (EGJP-insp). RESULTS The GEFV grade III and IV was more commonly found in patients with esophagitits (p < 0.05). The acid exposure time (AET%) and supine AET% were lower in patients with GEFV grade I (p < 0.01). There was weak correlation between AET% and GEFV grades (r = 0.27, p = 0.013). There were more EGJ morphology type III in patients with GEFV grade IV (p < 0.05).There were no significant differences on the values of four HRM metrics among the patients with different GEFV grades (p > 0.05). CONCLUSION The GEFV grades were associated with acid reflux positively and could be a good reflection of EGJ morphology in HRM. But it had no impact on the four HRM metrics. Our research revealed that GEFV may play an assistant role in the anti-reflux barrier.

Abstract
BACKGROUND Subtyping achalasia by high-resolution manometry (HRM) is clinically relevant as response to therapy and prognosis have shown to vary accordingly. The aim of this study was to assess inter- and intrarater reliability of diagnosing achalasia and achalasia subtyping in children using the Chicago Classification (CC) V3.0. METHODS Six observers analyzed 40 pediatric HRM recordings (22 achalasia and 18 non-achalasia) twice by using dedicated analysis software (ManoView 3.0, Given Imaging, Los Angeles, CA, USA). Integrated relaxation pressure (IRP4s), distal contractile integral (DCI), intrabolus pressurization pattern (IBP), and distal latency (DL) were extracted and analyzed hierarchically. Cohen's κ (2 raters) and Fleiss' κ (>2 raters) and the intraclass correlation coefficient (ICC) were used for categorical and ordinal data, respectively. RESULTS Based on the results of dedicated analysis software only, intra- and interrater reliability was excellent and moderate (κ=0.89 and κ=0.52, respectively) for differentiating achalasia from non-achalasia. For subtyping achalasia, reliability decreased to substantial and fair (κ=0.72 and κ=0.28, respectively). When observers were allowed to change the software-driven diagnosis according to their own interpretation of the manometric patterns, intra- and interrater reliability increased for diagnosing achalasia (κ=0.98 and κ=0.92, respectively) and for subtyping achalasia (κ=0.79 and κ=0.58, respectively). CONCLUSIONS Intra- and interrater agreement for diagnosing achalasia when using HRM and the CC was very good to excellent when results of automated analysis software were interpreted by experienced observers. More variability was seen when relying solely on the software-driven diagnosis and for subtyping achalasia. Therefore, diagnosing and subtyping achalasia should be performed in pediatric motility centers with significant expertise.

Abstract
BACKGROUND Alteration of esophageal function is a potential risk factor for postoperative complications in thoracic surgery. This prospective study investigates esophageal motility and function during and after thoracic procedures via high resolution manometry (HRM) and impedance technology with spatiotemporal representation of pressure data. METHODS Twelve consecutive patients eligible for elective thoracic surgery underwent preoperative and postoperative (48 hours and 7 days) esophageal HRM. Swallowing acts were carried out with 5 mL of water, 10 mL of water and 1 cm3 bread in physiological posture to evaluate distal contraction integral (DCI). Length and location of contractile integrity breaks were measured by investigators blinded to the form of surgical intervention. The impact of surgical procedures on esophageal motility was quantified according to current Chicago Classification (CC) criteria. Pre-, intra- and postoperative 24-hour multi-channel impedance pH-metry (MII-pH) was performed to further analyze gastroesophageal reflux patterns. RESULTS All patients were investigated 48 hours prior to and 7 days after thoracic procedures, with a total of n=675 swallowing acts being included in our study. Increased motility patterns of the tubular esophagus occurred temporally 48 hours postoperatively. DCI 48 hours after surgery increased significantly (5 mL, P=0.049; solid, P=0.014) and returned to baseline values after seven days (5 mL, P=0.039; solid, P=0.039). Break length was significantly reduced 48 hours postoperatively, especially in the proximal esophageal segment (transition zone). Follow-up measurements after another week were comparable to preoperative baseline findings. The perioperative MII-pH measurement showed numerous artifacts caused by intubation and ventilation during surgery also with increasing short and frequent acidic reflux episodes. CONCLUSIONS Thoracic procedures cause a transient modulation of esophageal peristalsis with postoperative increased contractility of the tubular esophagus, presumably without affecting intraesophageal reflex arcs. Although limited by the number of patients, we can conclude on our data that postoperative esophageal hypomotility is unlikely to promote secondary pulmonary complications.

Abstract
PURPOSE OF REVIEW The Chicago classification was based on metrics derived from studies in asymptomatic adult subjects. Our objectives were to characterize esophageal motility disorders in children and to determine whether the spectrum of manometric findings is similar between the pediatric and adult populations. RECENT FINDINGS Studies have suggested that the metrics utilized in manometric diagnosis depend on age, size, and manometric assembly. This would imply that a different set of metrics should be used for the pediatric population. There are no standardized and generally accepted metrics for use in the pediatric population, though there have been attempts to establish metrics specific to this population. Overall, we found that the distribution of esophageal motility disorders in children was like that described in adults using the Chicago classification. This analysis will serve as a prequel to follow-up studies exploring the individual metrics for variability among patients, with the objective of establishing novel metrics for the pediatric population.

Abstract
OBJECTIVE Sleep disturbance is common in patients with gastroesophageal reflux disease (GERD). Secondary peristalsis is important for clearance of the refluxate from the esophagus. We aimed to test the hypothesis whether secondary peristalsis is impaired in GERD patients with sleep disturbance. METHODS Secondary peristalsis was stimulated with slow and rapid air injections into mid-esophagus in 8 age-matched health controls and 41 patients with GERD. Sleep disturbance was assessed by the Pittsburg Sleep Quality Index (PSQI). Objective sleep measures were assessed by ambulatory actigraphy. RESULTS The threshold volume for inducing secondary peristalsis during slow air injection was significantly higher in GERD patients with sleep disturbance than healthy controls (14.3 ± 1.2 vs. 8.9 ± 0.5 mL, p < .05). GERD patients with sleep disturbance had higher threshold volume of secondary peristalsis during rapid air injection than GERD patients without sleep disturbance (5.1 ± 0.4 vs. 3.9 ± 0.2 mL, p < .05) and healthy controls (5.1 ± 0.4 vs. 3.6 ± 0.2 mL, p < .05). There was a negative correlation between PSQI score and peristaltic frequency during rapid air injection (r = -.39, p = .01). Secondary peristaltic amplitude during rapid air injection was negatively correlated with wake after sleep onset (r = -.34, p = .04). CONCLUSIONS Sleep disturbance is associated with secondary peristaltic response to distension-induced esophageal stimulation in patients with GERD. Our study suggests that sleep disturbance per se may adversely influence the effectiveness of esophageal peristalsis and bolus clearance during sleep in patients with GERD.

Abstract
Background/Aims Anti-reflux barrier dysfunction is one of the primary mechanisms in gastroesophageal reflux disease (GERD) pathogenesis. The esophagogastric junction contractile integral (EGJ-CI) is a new metric adopted to evaluate the EGJ contractility, which implies the anti-reflux barrier function. The aim of the current study was to validate this new metric in patients with GERD and its correlation with the esophageal acid exposure, as well as the efficacy of proton pump inhibitor treatment. Methods Ninety-eight patients with GERD and 21 healthy controls were included in the study. Upper endoscopy, high-resolution manometry (HRM) and 24-hour multichannel intraluminal impedance-pH monitoring were performed in all patients. Three respiration cycles were chosen at the initial HRM resting frame and the value computed with distal contractile integral tool was then divided by the duration of the cycles to yield EGJ-CI. All the patients were treated with esomeprazole 20 mg twice-daily for 8 weeks. Results EGJ-CI was lower in the patients with GERD than that of the controls (P < 0.05). For patients with GERD, EGJ-CI was lower in those with hiatal hernia (P < 0.05). The new metric correlated with esophageal acid exposure in the supine position (P < 0.05), and it also negatively correlated to the total reflux episodes (P < 0.05). There was no significant difference on EGJ-CI between patients with and without response to the esomeprazole treatment (P = 0.627). Conclusions EGJ-CI reflected the dysfunction of the anti-reflux barrier in patients with GERD, but it had little impact on the esomeprazole response.

Abstract
BACKGROUND AND AIM Esophageal motility disorders (EMDs) affect coordinated esophageal contractility. Recent developments in high-resolution manometry have improved diagnosis of EMDs; however, the etiology of EMDs remains to be determined. This study aimed to determine which clinical characteristics are associated with esophageal motility. METHODS From May 2013 to July 2014, 97 patients (54 women, 43 men; age, 16-89 years) with suspected EMDs were assessed by high-resolution manometry in Kyushu University Hospital. Esophageal motility was evaluated by measuring the distal contractile integral (DCI), basal lower esophageal sphincter pressure, and integrated relaxation pressure (IRP). Data on age, gender, body mass index (BMI), Brinkman Index, and blood tests were retrospectively collected and analyzed. RESULTS Fifty patients were diagnosed as normal, nine with achalasia, twelve with esophagogastric junction outflow obstruction, four with distal esophageal spasm, one with jackhammer esophagus, six with absent peristalsis, ten with frequent failed peristalsis, and five with weak peristalsis. The median DCI was 1229.0 mmHg-s-cm, the median basal lower esophageal sphincter pressure was 25.3 mmHg, and the median IRP was 9.6 mmHg. Patients with major motility disorders were excluded from analysis. By multivariate regression analysis, BMI (P = 0.029) and total cholesterol (P = 0.023) were negatively associated with DCI, while BMI (P = 0.007) was negatively associated with IRP and glucose (P = 0.044) was positively associated with IRP. CONCLUSIONS Both BMI and total cholesterol could be highly predictive factors for esophageal body contractility, while BMI and glucose could be predictive factors for lower esophageal sphincter contractile function.

Predictors of proton pump inhibitor failure in non-erosive reflux disease: A study with impedance-pH monitoring and high-resolution manometry. Neurogastroenterol Motil 2016; 28:674-9.

Abstract
BACKGROUND Approximately one-third of gastroesophageal reflux disease (GERD) patients have symptoms resistant to proton pump inhibitor (PPI). We used the high-resolution manometry (HRM) and multichannel intraluminal impedance-pH (MII-pH) monitoring to investigate potential predictors of PPI failure in non-erosive reflux disease (NERD) patients. METHODS One hundred and seventeen NERD patients were included, within which there were 44 PPI failure patients. The symptomatic questionnaire GerdQ, HRM and 24-hour MII-pH monitoring were performed before PPI therapy. PPI failure was defined as persistent reflux symptoms for more than 1 day during the last week on esomeprazole (20 mg twice daily) for continuous 4 weeks. The predictors for PPI failure were investigated by multivariable logistic regression analysis. KEY RESULTS Proton pump inhibitor failure patients had lower body mass index (BMI) and more concomitant functional dyspepsia (FD) symptoms. PPI failure patients had a higher percentage of type I esophagogastric junction (EGJ) morphology (p = 0.005), increased EGJ augmentation (p = 0.000), higher prevalence of esophageal motility disorders (p = 0.005) and a higher ratio of negative symptom index (SI, p = 0.000). Multivariable regression analysis showed that concomitance of FD symptoms, EGJ augmentation and negative SI were independent risk factors for PPI failure in NERD. CONCLUSIONS & INFERENCES Approximately half of PPI failure patients were found to have esophageal motility disorders in HRM. The independent risk factors for PPI failure in NERD were concomitant FD symptoms, increased EGJ augmentation and negative SI.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) has been introduced as a novel endoscopic treatment for achalasia. The aim of this work is to assess the changes in esophageal motility caused by POEM in patients with achalasia. METHODS Forty-one patients with achalasia underwent POEM from September 2012 to November 2014. Esophageal motility of all patients was evaluated preoperatively and 1 month after POEM utilizing high-resolution manometry, which was performed with ten water swallows, ten steamed bread swallows, and multiple rapid swallows (MRS). RESULTS In single swallows, including liquid swallows and bread swallows, all the parameters of lower esophagus sphincter resting pressure (LESP), 4-s integrated relaxation pressure (4sIRP), and intra-bolus pressure (IBP) were decreased between pre- and post-POEM patients (all p < 0.05). Postoperatively, the trend of distal contractile integral (DCI) and distal esophageal peristaltic amplitude declined in subtype II and subtype III (subtype II: p < 0.05; subtype III: p > 0.05), but increased in subtype I (subtype I: p > 0.05). In liquid swallows, the Eckardt score of subtype II patients decreased with DCI, and distal esophageal peristaltic amplitude after POEM was significantly lower compared with those showing increased values of those two parameters (p < 0.05). In MRS, the rate of LES relaxation increased from 66.67 to 95.24%, but without normal response in all achalasia patients. CONCLUSIONS POEM reduces LES pressure in achalasia, and partly restores esophageal motility. POEM displayed varying effect on esophageal motility in patients with different patterns of swallowing. In addition, the changes in parameters associated with esophageal peristalsis correlated with decreases in Eckardt score.

Abstract
BACKGROUND We aimed to define normative values for novel pressure topography metrics for high-resolution pharyngeal-esophageal manofluorography. The effects of age, gender, and bolus properties were examined. METHODS Concurrent high-resolution manometry (HRM) and videofluoroscopy data were collected from 22 younger (aged 21-40) and 22 older (aged 60-80) healthy subjects. Pressure topography was analyzed by correlating pressure domains with videofluoroscopic events. Nine pressure topography metrics of the pharyngeal and proximal esophageal swallow were extracted; four of these were also compared with previously obtained esophageal HRM studies to assess the effects of catheter diameter. KEY RESULTS Older individuals exhibited more vigorous contractility in the pharynx than did younger subjects with all bolus types, but the greatest values for both groups were with effortful swallow and on that measure the age groups were similar. Upper esophageal sphincter (UES) intrabolus pressure during sphincter opening was also greater in the older subjects. Some gender differences were observed, particularly related to proximal esophageal contractile vigor. Bolus consistency had no consistent effect. Studies using the larger catheter diameter resulted in significantly greater contractile vigor in the UES and proximal esophagus. CONCLUSIONS & INFERENCES Older adults exhibited more vigorous pharyngeal contractions than young adults, albeit within a similar range of capacity, perhaps reflecting a compensatory response to other age-related physiological changes. Greater UES intrabolus pressures observed during bolus transit in the older group likely reflect reduced UES compliance with age. Normative data on novel HRM metrics collected in this study can serve as a reference for future clinical studies.

Abstract
BACKGROUND In eosinophilic esophagitis (EoE), dysphagia, which might reflect esophageal dysmotility, is the most common symptom. High-resolution manometry (HRM) has become widely accepted for evaluating esophageal motility disorders, but to date has been sparsely examined in EoE patients, particularly under therapy. The aim of this study was to evaluate HRM in symptomatic EoE-patients under topical steroid treatment. METHODS In this prospective observational study, symptomatic EoE patients received HRM-examinations before and after 8 weeks of topical steroid treatment with budesonide. All HRM-abnormalities were assessed and interpreted according to the Chicago classification. The primary endpoint was the influence of topical steroid treatment on the intrabolus pressure (IBP). Clinical symptoms, endoscopic findings and histological esophageal eosinophilic load were also reported. KEY RESULTS Twenty symptomatic EoE patients were included. Overall success of budesonide therapy was 85% regarding complete histologic remission and 80% regarding complete clinical remission. High-resolution manometry showed abnormal esophageal motility in 35% of patients at baseline, which was resolved after therapy in 86% of these patients. Most frequent HRM-findings were early pan-esophageal pressurizations and weak persitalsis. There was no significant reduction of the IBP under therapy (before: 12.5 ± 4.9 mmHg, after: 10.9 ± 2.9 mmHg; p = 0.119). CONCLUSIONS & INFERENCES Although dysphagia is the leading symptom of EoE, HRM is able to identify esophageal motility disorders in only some EoE patients. Observed motility disorders resolve after successful treatment in almost all of these patients. Intrabolus pressure does not seem an optimal parameter for the monitoring of successful treatment response in EoE patients.

Abstract
Achalasia is a motility disorder of the esophagus characterized by dysphagia, regurgitation of undigested food, chest pain, weight loss and respiratory symptoms. The most common form of achalasia is the idiopathic one. Diagnosis largely relies upon endoscopy, barium swallow study, and high resolution esophageal manometry (HRM). Barium swallow and manometry after treatment are also good predictors of success of treatment as it is the residue symptomatology. Short term improvement in the symptomatology of achalasia can be achieved with medical therapy with calcium channel blockers or endoscopic botulin toxin injection. Even though few patients can be cured with only one treatment and repeat procedure might be needed, long term relief from dysphagia can be obtained in about 90% of cases with either surgical interventions such as laparoscopic Heller myotomy or with endoscopic techniques such pneumatic dilatation or, more recently, with per-oral endoscopic myotomy. Age, sex, and manometric type by HRM are also predictors of responsiveness to treatment. Older patients, females and type II achalasia are better after treatment compared to younger patients, males and type III achalasia. Self-expandable metallic stents are an alternative in patients non responding to conventional therapies.

Abstract
BACKGROUND Manometry is the gold-standard diagnostic test for motility disorders in the esophagus. The development of high-resolution manometry catheters and software displays of manometry recordings in color-coded pressure plots have changed the diagnostic assessment of esophageal disease. The diagnostic value of particular esophageal clinical symptoms among patients suspected of esophageal motor disorders (EMDs) is still unknown. The aim of this study was to explore the sensitivity, specificity, and predictive accuracy of presenting esophageal symptoms between abnormal and normal esophageal manometry findings. METHODS We conducted a cross-sectional study of 623 patients aged 11-80 years. Data were collected from clinical examinations as well as patient questionnaires. The sensitivity, specificity, and accuracy were calculated after high-resolution manometry plots were reviewed according to the most recent Chicago Criteria. RESULTS The clinical symptoms were not sensitive enough to discriminate between EMDs. Nevertheless, dysphagia, noncardiac chest pain, hoarseness, vomiting, and weight loss had high specificity and high accuracy to distinguish EMDs from normal findings. Regurgitation and heartburn did not have good accuracy for the diagnosis of EMDs. CONCLUSION Clinical symptoms are not reliable enough to discriminate between EMDs. Clinical symptoms can, however, discriminate between normal findings and EMDs, especially achalasia.

Abstract
AIM: To investigate the esophageal motility characteristics by high resolution manometry (HRM) in patients with different subtypes of achalasia categorized by 2014 Chicago classification criteria.
METHODS: Thirty untreated achalasia patients referred to our clinic between March 2014 and December 2014 were enrolled for HRM examination and typing by the Chicago classification criteria. The esophageal motility characteristics of different subtypes of achalasia were analyzed.
RESULTS: Of the 30 achalasia patients, 7 (23.3%) were classified as having subtype Ⅰ, 19 (63.3%) as having subtype Ⅱ and 4 (13.3%) as having subtype Ⅲ. No significant difference was found among the three subtypes in lower esophageal sphincter (LES) resting pressure, average LES length, average intraabdominal LES length and integrated relaxation pressure (IRP) (P > 0.05). The percentage of patients with panesophageal pressurization in subtype Ⅱ patients was 91.76% ± 3.12%, significantly higher than that of subtype Ⅲ patients (53.33% ± 11.81%, P < 0.05). Compared to subtype Ⅰ patients, upper esophageal sphincter (UES) resting pressure was significantly higher in subtype Ⅱ patients (65.74 mmHg ± 5.21 mmHg vs 38.73 mmHg ± 3.37 mmHg, P < 0.05), but no significant difference was noted between subtypes Ⅰ and Ⅲ or between subtypes Ⅱ and Ⅲ. Although no significant difference was found among the three subtypes in UES residual pressure, in subtype Ⅱ, UES residual pressure was 13.41 mmHg ± 1.55 mmHg, higher than normal value (12 mmHg), which means abnormal relaxation of UES.
CONCLUSION: In patients with achalasia, subtype Ⅱ is more common. Subtype Ⅱ patients often exhibit LES relaxation disorder, panesophageal pressurization, UES resting pressure increase and UES abnormal relaxation. HRM contributes to early diagnosis and accurate classification and thus helps to make proper treatment choices.

Abstract
Oesophageal dysphagia is a common symptom, which might be related to severe oesophageal diseases such as carcinomas. Therefore, an organic process must be ruled out in the first instance by endoscopy in all patients presenting with dysphagia symptoms. The most prevalent obstructive aetiologies are oesophageal cancer, peptic strictures and eosinophilic oesophagitis. Eosinophilic oesophagitis is one of the most common causes of dysphagia in adults and children, thus justifying the need to obtain oesophageal biopsy samples from all patients presenting with unexplained dysphagia. With the advent of standardized high-resolution manometry and specific metrics to characterize oesophageal motility, the Chicago classification has become a gold-standard algorithm for manometric diagnosis of oesophageal motor disorders. In addition, sophisticated investigations and analysis methods that combine pressure and impedance measurement are currently in development. In the future, these techniques might be able to detect subtle pressure abnormalities during bolus transport, which could further explain pathophysiology and symptoms. The degree to which novel approaches will help distinguish dysphagia caused by motor abnormalities from functional dysphagia still needs to be determined.

Abstract
More than a century has elapsed since the identification of Clostridia neurotoxins as the cause of paralytic diseases. Clostridium botulinum is a heterogeneous group of Gram-positive, rod-shaped, spore-forming, obligate anaerobic bacteria that produce a potent neurotoxin. Eight different Clostridium botulinum neurotoxins have been described (A-H) and 5 of those cause disease in humans. These toxins cause paralysis by blocking the presynaptic release of acetylcholine at the neuromuscular junction. Advantage can be taken of this blockade to alleviate muscle spams due to excessive neural activity of central origin or to weaken a muscle for treatment purposes. In therapeutic applications, minute quantities of botulinum neurotoxin type A are injected directly into selected muscles. The Food and Drug Administration first approved botulinum toxin (BT) type A in 1989 for the treatment of strabismus and blepharospasm associated with dystonia in patients 12 years of age or older. Ever since, therapeutic applications of BT have expanded to other systems, including the gastrointestinal tract. Although only a single fatality has been reported to our knowledge with use of BT for gastroenterological conditions, there are significant complications ranging from minor pain, rash and allergic reactions to pneumothorax, bowel perforation and significant paralysis of tissues surrounding the injection (including vocal cord paralysis and dysphagia). This editorial describes the clinical experience and evidence for the use BT in gastrointestinal motility disorders in children.

Abstract
The standard protocol for esophageal manometry involves placing the patient in the supine position with head turned to left (supine head left [SHL]) while evaluating liquid bolus swallows. Routinely, semisolid or solid boluses are not evaluated. Currently, the daily American diet includes up to 40% solid or semisolid texture. Thus far, the data on the effect of different bolus on high-resolution esophageal pressure topography (HREPT) parameters are scarce. This study aims to evaluate the effect of every day bolus consistencies in different body positions on HREPT variables. HREPT was performed on healthy volunteers with a modified protocol including liquid swallows in the SHL position followed by applesauce (semisolid), cracker (solid), and marshmallow (soft solid) in three different positions (SHL, sitting, and standing). A total of 38 healthy adult subjects (22 males and 16 females, median age = 27, and mean body mass index = 25) were evaluated. The resting upper esophageal sphincter pressure was significantly different while subjects swallowed crackers, applesauce, and marshmallows in most positions compared with liquid SHL (P < 0.05). The lower esophageal sphincter, contractile front velocity, and distal contractile integral pressures did not differ in all different consistencies compared with SHL. The integrated relaxation period was significantly higher with solid bolus compared with liquid bolus only in SHL position. The intrabolus pressure was significantly different with solid and soft solid boluses in all postures compared to liquid SHL. The American diet consistency affects upper esophageal sphincter pressure and partially integrated relaxation period and intrabolus pressure in various positions. Semisolid bolus swallows do not cause substantial pressure changes and are safe for evaluation and maintaining adequate caloric intake in patients with dysphagia who cannot tolerate solids.

Abstract
BACKGROUND Intolerance of the esophageal manometry catheter may prolong high-resolution manometry (HRM) studies and increase patient distress. We assessed the impact of obtaining the landmark phase at the end of the study when the patient has acclimatized to the HRM catheter. METHODS 366 patients (mean age 55.4 ± 0.8 years, 62.0% female) undergoing esophageal HRM over a 1-year period were studied. The standard protocol consisted of the landmark phase, 10 5 mL water swallows 20-30 s apart, and multiple rapid swallows where 4-6 2 mL swallows were administered in rapid succession. The modified protocol consisted of the landmark phase at the end of the study after test swallows. Study duration, technical characteristics, indications, and motor findings were compared between standard and modified protocols. KEY RESULTS Of the 366 patients, 89.6% underwent the standard protocol (study duration 12.9 ± 0.3 min). In 10.4% with poor catheter tolerance undergoing the modified protocol, study duration was significantly longer (15.6 ± 1.0 min, p = 0.004) despite similar duration of study maneuvers. Only elevated upper esophageal sphincter basal pressures at the beginning of the study segregated modified protocol patients. The 95th percentile time to landmark phase in the standard protocol patients was 6.1 min; as many as 31.4% of modified protocol patients could not obtain their first study maneuver within this period (p = 0.0003). Interpretation was not impacted by shifting the landmark phase to the end of the study. CONCLUSIONS & INFERENCES Modification of the HRM study protocol with the landmark phase obtained at the end of the study optimizes study duration without compromising quality.

Abstract
BACKGROUND The Chicago Classification (CC) facilitates interpretation of high-resolution manometry (HRM) recordings. Application of this adult based algorithm to the pediatric population is unknown. We therefore assessed intra and interrater reliability of software-based CC diagnosis in a pediatric cohort. METHODS Thirty pediatric solid state HRM recordings (13M; mean age 12.1 ± 5.1 years) assessing 10 liquid swallows per patient were analyzed twice by 11 raters (six experts, five non-experts). Software-placed anatomical landmarks required manual adjustment or removal. Integrated relaxation pressure (IRP4s), distal contractile integral (DCI), contractile front velocity (CFV), distal latency (DL) and break size (BS), and an overall CC diagnosis were software-generated. In addition, raters provided their subjective CC diagnosis. Reliability was calculated with Cohen's and Fleiss' kappa (κ) and intraclass correlation coefficient (ICC). KEY RESULTS Intra- and interrater reliability of software-generated CC diagnosis after manual adjustment of landmarks was substantial (mean κ = 0.69 and 0.77 respectively) and moderate-substantial for subjective CC diagnosis (mean κ = 0.70 and 0.58 respectively). Reliability of both software-generated and subjective diagnosis of normal motility was high (κ = 0.81 and κ = 0.79). Intra- and interrater reliability were excellent for IRP4s, DCI, and BS. Experts had higher interrater reliability than non-experts for DL (ICC = 0.65 vs ICC = 0.36 respectively) and the software-generated diagnosis diffuse esophageal spasm (DES, κ = 0.64 vs κ = 0.30). Among experts, the reliability for the subjective diagnosis of achalasia and esophageal gastric junction outflow obstruction was moderate-substantial (κ = 0.45-0.82). CONCLUSIONS & INFERENCES Inter- and intrarater reliability of software-based CC diagnosis of pediatric HRM recordings was high overall. However, experience was a factor influencing the diagnosis of some motility disorders, particularly DES and achalasia.

Abstract
BACKGROUND Relaxation of the esophagogastric junction (EGJ) is now evaluated calculating 4-second integrated relaxation pressure (4-s IRP) by high resolution manometry (HREPT). Solid-state catheters have been used to define abnormal values. Our aim was to evaluate 4-s IRP in esophageal achalasia using HREPT with perfused catheters. METHODS From June 2009 to June 2013, 936 HREPT studies have been performed in our unit. Of these, 194 patients having treated achalasia were excluded. Control group was constituted by 695 patients without achalasia, and 47 patients with untreated achalasia constituted the study group. HREPT was performed with water-perfused catheters. To establish the cut-off value for 4-s IRP that better discriminate patients with achalasia from all other patients, a receiver operating characteristic (ROC) analysis was performed. KEY RESULTS Twenty three of 47 achalasia patients (49%) showed a 4-s IRP under 15 mmHg; and seven (15%) had a value under modified Chicago criteria. A cut-off value for 4-s IRP of 6.5 mmHg, calculated by ROC analysis, highly discriminates achalasia from the rest of the patients and especially from scleroderma patients (area under the curve: 0.997, 95% CI: 0.995-1.000; p < 0.001). CONCLUSIONS & INFERENCES Cut-off values for 4-s IRP defined using HREPT with solid-state catheters are not adequate for diagnosing esophageal achalasia with water-perfused systems. A lower value, i.e., 6.5 mmHg, is suggested for this equipment. The diagnostic criteria of esophageal achalasia should be modified for HREPT performed with water-perfused systems.

Abstract
BACKGROUND Three variants of Achalasia have been described using high-resolution esophageal manometry (HRM). While manometrically distinct, their clinical significance has yet to be established. Our objective was to compare the outcome after myotomy in patients with these Achalasia subtypes. METHODS A retrospective chart review was performed to identify patients with Achalasia who had HRM and who underwent Heller myotomy or Per oral endoscopic myotomy (POEM). Symptoms and esophageal clearance by timed barium study were compared before and after treatment. RESULTS We identified 49 patients, 21 males and 28 females, with a median age of 52 years. The primary symptom in all patients was dysphagia, with a median duration of 4 years (range 4 months-50 years). By HRM, ten patients (20 %) were classified as Type I, 30 (61 %) as Type II, and 9 (18 %) as Type III. At a median follow-up of 16 months after myotomy (range 1-63 months), the median Eckardt score was zero and was similar across subtypes. Relief of dysphagia was also similar across subtypes (80 % of Type I, 93 % of Type II and 89 % of Type III). On pre-treatment timed barium study, no patient had complete emptying at 1 or 5 min. After myotomy, complete emptying occurred within 1 min in 50 % (20/40) and within 5 min in 60 % (24/40) and was similar across groups. CONCLUSION Myotomy for Achalasia results in excellent symptomatic outcome and improvement in esophageal clearance. There was no difference among the described HRM Achalasia variants. This calls into question the clinical utility of Achalasia sub-classification and affirms the benefit of myotomy for this disease.

Abstract
Peroral endoscopic myotomy (POEM) has been developed as a minimally invasive endoscopic treatment for achalasia for years. However, the optimal length of submucosal tunnel and myotomy of muscle bundles during procedure of POEM has not yet been determined, so we aim to assess safety and efficacy of modified POEM with shorter myotomy of muscle bundles in achalasia patients. Consecutive achalasia patients had been performed modified POEM with shorter myotomy, and assessed by symptoms, high-resolution manometry, and barium swallow examinations before and 3 months after POEM for safety and efficacy evaluation. Modified POEM with shorter submucosal tunnel (mean length 6.8 cm) and endoscopic myotomy of muscle bundles (total mean length 5.4 cm) were completed in 46 consecutive achalasia patients. During the 3-month follow up in all cases, significant improvement of symptoms (a significant drop in the Eckardt score 8.4 ± 3.2 vs. 2.7 ± 1.9; P < 0.001), decreased lower esophageal sphincter pressure (39.4 ± 10.1 vs. 24.4 ± 9.1 mmHg; P < 0.001) and integrated relaxation pressure (38.6 ± 10.4 vs. 25.7 ± 9.6 mmHg; P < 0.01), and a drop in height of esophagus barium-contrast column (5.4 ± 3.1 vs. 2.6 ± 1.8 cm; P < 0.001) were observed. The frequencies of adverse events were lower in those under endotracheal anesthesia and CO2 insufflations compared with intravenous anesthesia and air insufflations. Only three patients were found to have gastroesophageal reflux disease on follow up. Modified POEM with shorter myotomy under endotracheal anesthesia and CO2 insufflations shows its good safety and excellent short-term efficacy in the treatment of achalasia. But further studies are warranted to assess the long-term efficacy.

Abstract
UNLABELLED High resolution esophageal manometry (HREM) has been interpreted all along by visual interpretation of color plots until the recent introduction of Chicago classification which categorises HREM using objective measurements. It compares HREM diagnosis of esophageal motor disorders by visual interpretation and Chicago classification. Using software Trace 1.2v, 77 consecutive tracings diagnosed by visual interpretation were re-analyzed by Chicago classification and findings compared for concordance between the two systems of interpretation. STATISTICAL ANALYSIS Kappa agreement rate between the two observations was determined. There were 57 males (74 %) and cohort median age was 41 years (range: 14-83 years). Majority of the referrals were for gastroesophageal reflux disease, dysphagia and achalasia. By "intuitive" visual interpretation, the tracing were reported as normal in 45 (58.4 %), achalasia 14 (18.2 %), ineffective esophageal motility 3 (3.9 %), nutcracker esophagus 11 (14.3 %) and nonspecific motility changes 4 (5.2 %). By Chicago classification, there was 100 % agreement (Kappa 1) for achalasia (type 1: 9; type 2: 5) and ineffective esophageal motility ("failed peristalsis" on visual interpretation). Normal esophageal motility, nutcracker esophagus and nonspecific motility disorder on visual interpretation were reclassified as rapid contraction and esophagogastric junction (EGJ) outflow obstruction by Chicago classification. Chicago classification identified distinct clinical phenotypes including EGJ outflow obstruction not identified by visual interpretation. A significant number of unclassified HREM by visual interpretation were also classified by it.

Abstract
BACKGROUND AND AIMS The study aimed to investigate the hypothesis whether the presence of Ineffective esophageal motility would affect physiological characteristics of secondary peristalsis. METHODS Secondary peristalsis was performed with slow and rapid air injections into mid-esophagus of 18 ineffective esophageal motility patients and 15 age-matched controls. Severity of ineffective esophageal motility was defined by the application of combined multichannel intraluminal impedance and manometry. RESULTS Ineffective esophageal motility patients included 11 patients without impedance abnormality and seven patients with impedance abnormality during liquid and/or viscous swallowing. The prevalence of failed secondary peristaltic response during slow air injection was significantly greater in ineffective esophageal motility patients without impedance abnormality (3/11 [27%], P < 0.001) and with impedance abnormality (4/7 [57%], P = 0.04) than healthy subjects. The threshold volume for inducing secondary peristalsis during rapid air injection was significantly greater in ineffective esophageal motility patients with impedance abnormality (6.1 ± 0.3 mL) than healthy subjects (4.6 ± 0.3 mL, P < 0.05) and ineffective esophageal motility patients without impedance abnormality (4.1 ± 0.4 mL, P < 0.05). The frequency of peristaltic response during rapid air injection was significantly lower in ineffective esophageal motility patients with impedance abnormality (40% [20-50%] than healthy subjects (90% [90-100%], P < 0.05). CONCLUSIONS Defective activation of secondary peristalsis is present in ineffective esophageal motility patients with impedance abnormality. Our study indicates that increased ineffective esophageal motility severity associated with defective triggering of secondary peristalsis may contribute to impaired esophageal clearance in patients with gastroesophageal reflux disease.

Abstract
Achalasia is a rare motility disorder of the oesophagus characterised by loss of enteric neurons leading to absence of peristalsis and impaired relaxation of the lower oesophageal sphincter. Although its cause remains largely unknown, ganglionitis resulting from an aberrant immune response triggered by a viral infection has been proposed to underlie the loss of oesophageal neurons, particularly in genetically susceptible individuals. The subsequent stasis of ingested food not only leads to symptoms of dysphagia, regurgitation, chest pain, and weight loss, but also results in an increased risk of oesophageal carcinoma. At present, pneumatic dilatation and Heller myotomy combined with an anti-reflux procedure are the treatments of choice and have comparable success rates. Per-oral endoscopic myotomy has recently been introduced as a new minimally invasive treatment for achalasia, but there have not yet been any randomised clinical trials comparing this option with pneumatic dilatation and Heller myotomy.

Abstract
Background/Aims Achalasia is classified into 3 types according to the Chicago classification. The aim of this study was to investigate characteristics and treatment outcomes of 3 achalasia subtypes in Korean patients. Methods Fifty-five patients diagnosed with achalasia based on conventional or high-resolution esophageal manometry were consecutively enrolled. Their clinical characteristics, manometric, endoscopic and esophagographic findings and treatment responses were analyzed among the 3 subtypes of achalasia. Results Of 55 patients, 21 (38.2%) patients had type I, 28 (50.9%) patients had type II and 6 (10.9%) patients had type III. The median follow-up period was 22.4 (interquartile range, 3.6-67.4) months. Type III patients were older than type I and II patients (70.0 vs. 46.2 and 47.6 years, P = 0.023). The width of the esophagus in type I patients was wider with more frequent bird's beak appearance on esophagogram than the other 2 types (P = 0.010 and 0.006, respectively). Of the 50 patients who received the evaluation for treatment response at 3 months, 7 patients (36.8% vs. 26.9%) were treated with pneumatic dilatation and 4 patients (21.1% vs. 15.4%) with laparoscopic Heller's myotomy in type I and II groups, respectively. The treatment responses of pneumatic dilatation and Heller's myotomy in type I group were 71.4 and 50.0% and in type II were 85.7 and 75.0%, respectively, and all 5 patients in type III group showed good response to medical therapy. Conclusions Clinical characteristics of 3 achalasia subtypes in Korean patients are consistent with other studies. Treatment outcomes are variable among 3 subtypes.

Abstract
BACKGROUND AND AIM Current normative data of high-resolution manometry have been obtained from Western populations, and esophageal motility disorders have been categorized using Chicago classification. However, the utility of high-resolution impedance manometry (HRiM) in the Chinese population has not been evaluated. The study aimed to investigate the normal reference of esophageal motility in healthy volunteers (as defined by Chicago classification) using HRiM. METHODS Healthy, fasted volunteers underwent HRiM in a supine position with 10 liquid swallows and 10 viscous swallows. Integrated relaxation pressure (IRP), distal contractile integral (DCI), contractile front velocity (CFV), and distal latency were calculated. The interquartile ranges and the 95th percentile range for each metric were obtained. RESULTS Forty-two healthy volunteers were enrolled with 411 total liquid swallows and 398 viscous swallows available for analysis. A 20.5 mmHg of IRP and a 3195 mmHg·s·cm of DCI as the 95th percentile for liquid swallows were established. Using the reference range defined by Chicago classification, 6.3% (26/411) weak peristalsis and 0.7% (3/411) failed peristalsis for liquid swallows were observed; 12 (28.6%, 12/42) and 2 (4.7%, 2/42) individuals were diagnosed as esophagogastric junction outflow obstruction and weak peristalsis for liquid swallows. Compared with liquid swallows, viscous swallows had a decreased IRP (P = 0.000) and CFV (P = 0.000), and an unchanged DCI (P = 0.211). CONCLUSIONS HRiM normative data of both liquid and viscous swallows from healthy Chinese volunteers were established. The IRP and CFV were significantly decreased in the viscous swallows compared with those of the liquid swallows.

Abstract
Recent advances in the treatment of achalasia include the use of high-resolution manometry to predict the outcome of patients and the introduction of peroral endoscopic myotomy (POEM). The first multicenter randomized, controlled, 2-year follow-up study conducted by the European Achalasia Trial group indicated that laparoscopic Heller myotomy (LHM) was not superior to pneumatic dilations (PD). Publications on the long-term success of laparoscopic surgery continue to emerge. In addition, laparoscopic single-site surgery is applicable to advanced laparoscopic operations such as LHM and anterior fundoplication. The optimal treatment option is an ongoing matter of debate. In this review, we provide an update of the current progress in the treatment of esophageal achalasia. Unless new conclusive data prove otherwise, LHM is considered the most durable treatment for achalasia at the expense of increased reflux-associated complications. However, PD is the first choice for non-surgical treatment and is more cost-effective. Repeated PD according to an “on-demand” strategy based on symptom recurrence can achieve long-term remission. Decision making should be based on clinical evidence that identifies a subcategory of patients who would benefit from specific treatment options. POEM has shown promise but its long-term efficacy and safety need to be assessed further.

Abstract
The pathophysiology of chronic cough and its association with dsymotility and laryngopharyngeal reflux remains unclear. This study applied high-resolution manometry (HRM) to obtain a detailed evaluation of pharyngeal and esophageal motility in chronic cough patients with and without a positive reflux-cough symptom association probability (SAP). Retrospective analysis of 66 consecutive patients referred for investigation of chronic cough was performed. Thirty-four (52%) were eligible for inclusion (age 55 [19-77], 62% female). HRM (ManoScan 360, Given/Sierra Scientific Instruments, Mountain View, CA) with 10 water swallows was performed followed by a 24-hour ambulatory pH monitoring. Of this group, 21 (62%) patients had negative reflux-cough SAP (group A) and 13 (38%) had positive SAP (group B). Results from 23 healthy controls were available for comparison (group C). Detailed analysis revealed considerable heterogeneity. A small number of patients had pathological upper esophageal sphincter (UES) function (n=9) or esophageal dysmotility (n=1). The overall baseline UES pressure was similar, but average UES residual pressure was higher in groups A and B than in control group C (-0.2 and -0.8mmHg vs. -5.4mmHg; P<0.018 and P<0.005). The percentage of primary peristaltic contractions was lower in group B than in groups A and C (56% vs. 79% and 87%; P=0.03 and P<0.002). Additionally, intrabolus pressure at the lower esophageal sphincter was higher in group B than in group C (15.5 vs. 8.9; P=0.024). HRM revealed changes to UES and esophageal motility in patients with chronic cough that are associated with impaired bolus clearance. These changes were most marked in group B patients with a positive reflux-cough symptom association.

Abstract
Although conventional manometry set the basis for the diagnosis of esophageal motility disorders, the large axial spacing between recording sites leaves large portions of the esophagus unevaluated and vulnerable to movement artifact. However, continuous spatiotemporal representations of pressure through the esophagus recorded with high-resolution manometry offers greater detail and improved accuracy for many of the most important measurements of esophageal motor function. This review describes how the new classification schemes for esophageal pressure topography have evolved from conventional criteria and focuses on how esophageal pressure topography has improved the ability to subcategorize conventional manometric diagnoses into new functional phenotypes.

Interobserver variability in esophageal body measurements with high-resolution manometry among new physician users. J Clin Gastroenterol 2013; 47:e12-6.

Abstract
GOALS To evaluate interobserver variability among 4 new physician users on measures of esophageal body function. BACKGROUND Esophageal high-resolution manometry allows observation of esophageal motility by pressure topography plots. Little is known about the interobserver variability among physicians. STUDY Two resident and 2 fellow level physicians each interpreted 10 liquid swallows of 20 esophageal high-resolution manometry studies (n = 200 swallows) using the BioVIEW Analysis Suite (Sandhill Scientific Inc.). Studies evaluated were from patients referred for evaluation of dysphagia but found to have normal esophageal manometry and complete liquid bolus transit. Physicians received an orientation session and reviewed recent literature. Each physician recorded contractile front velocity (CFV) and distal contractile integral (DCI) for each liquid swallow. STATISTICS Interobserver agreements for CFV and DCI were assessed by intraclass correlation (ICC) values. Linear correlations between measurements by 2 readers were assessed using linear regression modeling techniques. RESULTS CFV and DCI values of up to 200 data points were analyzed. Four reader results for CFV and DCI showed strong agreement although stronger for DCI measures (ICC = 0.94; range, 0.91 to 0.98) in comparison with CFV (ICC = 0.79; range, 0.52 to 0.82). Further correlation was performed with 2 readers; readers 1 and 2 revealed excellent correlation for DCI (r = 0.95, P < 0.001) and good correlation for CFV (r = 0.61, P < 0.001). CONCLUSIONS With a thorough orientation session, good to excellent agreement for CFV and DCI measurements can be obtained from new physician users. CFV measures exhibit greater interobserver variability possibly due to the artifact produced by intraesophageal pressurization.
