J Neurogastroenterol Motil 2024; 30:156-165. [PMID: 38062800 PMCID: PMC10999846 DOI: 10.5056/jnm23017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 05/10/2023] [Accepted: 07/07/2023] [Indexed: 04/06/2024] Open
Abstract
Background/Aims There is an increased incidence of gastroesophageal reflux disease (GERD) after lung transplantation (LT) that can be associated with graft dysfunction. It is unclear if the underlying esophageal motility changes in GERD are different following LT. This study aimed to use esophageal high-resolution manometry (HRM) to explore GERD mechanisms in LT recipients compared to matched controls. Methods This was a retrospective study including patients with pathologic acid reflux who underwent HRM and pH testing at our healthcare facility July 2012 to October 2019. The study included 12 LT recipients and 36 controls. Controls were matched in a 1:3 ratio for age, gender, and acid exposure time (AET). Results LT recipients had less hypotensive esophagogastric junction (EGJ) (mean EGJ-contractile integral 89.2 mmHg/cm in LT vs 33.9 mmHg/cm in controls, P < 0.001). AET correlated with distal contractile integral and total EGJ-contractile integral only in LT group (r = -0.79, P = 0.002 and r = -0.57, P = 0.051, respectively). Conclusions Following LT, acid reflux is characterized by a less hypotensive EGJ compared to controls with similar AET. The strongest correlation with AET after LT was found to be esophageal peristaltic vigor. These results add to the understanding of reflux after LT and may help tailor an individualized treatment plan.

Min HJ, Park JY. Usefulness of nasal cavity evaluation before high-resolution esophageal manometry in high-risk patients. Korean J Intern Med 2024; 39:86-94. [PMID: 38031365 PMCID: PMC10790053 DOI: 10.3904/kjim.2023.266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 07/10/2023] [Accepted: 07/21/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND/AIMS A catheter is inserted through the nasal cavity during high-resolution esophageal manometry (HRM), which may cause adverse events such as pain or epistaxis. Despite these possible safety considerations, studies on this subject are very limited. We aimed to investigate the usefulness of nasal cavity evaluation before HRM to reduce the risk of adverse events and test failure. METHODS Patients who underwent HRM after consultation with the ear-nose-throat department for nasal evaluation were retrospectively enrolled between December 2021 and May 2022. The included patients had a previous history of sinonasal disease or surgery or had subjective nasal discomfort. All patients answered the Sino-Nasal Outcome Test (SNOT-22) questionnaire, and subjective nasal discomfort was scored using a visual analog scale. Nasal endoscopy and acoustic rhinometry were performed for disease evaluation and volumetric assessment. RESULTS The analysis included 22 patients with a mean age of 58.9 years. The mean SNOT-22 score was 24.2, and 16 patients (72.7%) complained of subjective nasal obstruction. The HRM catheter was successfully inserted in 20 patients (90.9%), without any significant adverse events. The objective measurement outcomes of acoustic rhinometry and sinus endoscopy did not always correspond to subjective symptoms. Narrowed nasal airways unresponsive to decongestants were observed in two patients with failed catheter insertion. CONCLUSION To reduce the risk of adverse events and test failure during HRM, a site-specific questionnaire to evaluate nasal obstruction might be helpful. When nasal obstruction is suspected, objective nasal cavity evaluation could be recommended for the safe and successful performance of HRM.

Abstract
Diseases of the esophageal tract represent a heterogeneous class of pathological conditions for which diagnostic paradigms continue to emerge. In the last few decades, innovative diagnostic devices have been developed, and several attempts have been made to advance and standardize diagnostic algorithms to be compliant with medical procedures. To the best of our knowledge, a comprehensive review of the procedures and available technologies to investigate the esophageal tract was missing in the literature. Therefore, the proposed review aims to provide a comprehensive analysis of available endoluminal technologies and procedures to investigate esophagus health conditions. The proposed systematic review was performed using PubMed, Scopus, and Web of Science databases. Studies have been divided into categories based on the type of evaluation and measurement that the investigated technology provides. In detail, three main categories have been identified, i.e., endoluminal technologies for the (i) morphological, (ii) bio-mechanical, and (iii) electro-chemical evaluation of the esophagus.

Heslin N, Regan J. Effect of effortful swallow on pharyngeal pressures during swallowing in adults with dysphagia: A pharyngeal high-resolution manometry study. INTERNATIONAL JOURNAL OF SPEECH-LANGUAGE PATHOLOGY 2022; 24:190-199. [PMID: 34607470 DOI: 10.1080/17549507.2021.1975817] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/13/2023]
Abstract
Purpose: Evidence base to support the use of the effortful swallow in clinical populations with dysphagia is currently lacking. This study aims to quantify the effects of effortful swallowing on pharyngeal swallowing biomechanics in adults with dysphagia using pharyngeal high-resolution manometry (PHRM).Method: ManoScan HRM equipment with a 4.2 mm pressure catheter was used. Participants completed duplicate 10ml baseline and 10ml effortful liquid (IDDSI Level 0) swallows in randomised order. PHRM data were analysed using a semi-automated online platform (www.swallowgateway.com).Result: Fifteen adults (8 males; range 45-86 years) with mixed aetiology dysphagia (Functional Oral Intake Scale Level 2-5) were included. Median pharyngeal contractile (156.81 mmHg cm s; IQR 80.62) increased significantly (213.50 mmHg cm s; IQR 117.2) during effortful swallowing. Significant increases were also observed in velopharyngeal pressure, mesopharyngeal pressure, hypopharyngeal pressure and upper oesophageal sphincter (UOS) relaxation duration. UOS integrated relaxation pressure (IRP) was not significantly altered with effortful swallowing.Conclusion: Effortful swallowing induced significant biomechanical changes to swallow in adults with dysphagia. Increases in global pharyngeal rigour, tongue base pressure and UOS opening duration were captured by PHRM during effortful swallowing. Further investigation in larger homogeneous clinical populations is needed to verify the physiological effects of this frequently employed intervention.

Laryngoscope 2022; 132:2124-2131. [PMID: 34989412 DOI: 10.1002/lary.30010] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 12/03/2021] [Accepted: 12/22/2021] [Indexed: 11/10/2022]
Abstract
OBJECTIVES/HYPOTHESIS Use of topical nasal anesthetic (TNA) is common in high-resolution impedance manometry (HRIM). This study investigated the effect of TNA on swallowing and procedure tolerability during HRIM with a 4.2-mm catheter, a more commonly used catheter size with impedance capabilities. STUDY DESIGN Randomised experimental study with blinding of participants. METHODS Twenty healthy participants (mean age = 33 years, 16 female) were randomized to undergo HRIM using the ManoScan™ ESO Z 4.2-mm catheter twice, 1 week apart, under two conditions: with TNA (viscous lidocaine) and with placebo. Analyses included esophageal data of three saliva, three saline (5 mL), and three bread swallows (2 cm × 2 cm) performed while reclined 45°, and pharyngeal data under the same conditions while seated upright. Pharyngeal and upper esophageal sphincter (UES) HRIM parameters were analyzed using the Swallow Gateway analysis platform. Visual analogue scale (VAS) scores rating procedural comfort were analyzed. RESULTS There were no significant physiological differences in pharyngeal and UES parameters between conditions. There were also no significant differences in VAS scores under placebo (mean = 54.8, standard deviation (SD) = 19.3) and TNA (mean = 60.0, SD = 21.9) (t[19] = -0.9, P = .4) conditions; however, there was a significant difference in the first versus second session (t[19]) = 5.1, P < .05). CONCLUSIONS TNA did not improve comfort, but it also did not significantly affect swallowing behavior. There was, however, a practice effect regardless of TNA use with improved tolerance of the 4.2-mm catheter and likely more natural swallowing behavior during the second session of HRIM. LEVEL OF EVIDENCE 3 Laryngoscope, 2022.

Optimal cutoff value of integrated relaxation pressure on the esophagogastric junction to detect outflow obstruction using starlet high-resolution manometry system. J Gastroenterol 2021; 56:231-239. [PMID: 33423114 DOI: 10.1007/s00535-020-01757-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2020] [Accepted: 12/19/2020] [Indexed: 02/04/2023]
Abstract
BACKGROUND Achalasia and esophagogastric junction outflow obstruction (EGJOO) are idiopathic esophageal motility disorders characterized by impaired deglutitive relaxation of the lower esophageal sphincter (LES). High-resolution manometry (HRM) provides integrated relaxation pressure (IRP) which represents adequacy of LES relaxation. The Starlet HRM system is widely used in Japan; however, IRP values in achalasia/EGJOO patients assessed with the Starlet system have not been well studied. We propose the optimal cutoff of IRP for detecting achalasia/EGJOO using the Starlet system. METHODS Patients undergone HRM test using the Starlet system at our institution between July 2018 and September 2020 were included. Of these, we included patients with either achalasia or EGJOO and those who had normal esophageal motility without hiatal hernia. Abnormally impaired LES relaxation (i.e., achalasia and EGJOO) was diagnosed if prolonged esophageal emptying was evident based on timed barium esophagogram (TBE). RESULTS A total of 111 patients met study criteria. Of these, 48 patients were diagnosed with achalasia (n = 45 [type I, n = 20; type II, n = 22; type III, n = 3]) or EGJOO (n = 3). In the 48 patients who had a prolonged esophageal clearance based on TBE, IRP values distributed along a wide-range of minimal 14.1 to a maximal of 72.2 mmHg. The optimal cutoff value of IRP was 24.7 mmHg with sensitivity of 89.6% and specificity of 84.1% (AUC 0.94). CONCLUSION The optimal cutoff value of IRP to distinguish achalasia/EGJOO was ≥ 25 mmHg using the Starlet HRM system in our cohort. This indicates that the current proposed cutoff of 26 mmHg appears to be relevant.

Abstract
Establishing normative values of high-resolution esophageal manometry is necessary for accurate interpretation and comparison of measurements. In this systematic review, we aimed to summarize normal values for different esophageal high-resolution manometry systems. Moreover, we assessed the effect of body position, bolus consistency, and provocative maneuvers on these normative thresholds. We searched Medline, Embase, and the Cochrane Library from January 1st, 2006, to January 20th, 2020, for studies that reported normative data of high-resolution manometry in healthy volunteers. We assessed methodological quality of the included studies and planned a descriptive analysis. We analyzed data from 54 articles describing normative thresholds in high-resolution manometry using solid-state or water-perfused systems. Forty-six studies performed the manometry study in the supine position with liquid swallows, whereas sixteen studies described normative values in the upright position. Twelve studies assessed normative values for different bolus consistencies, and nine studies evaluated different provocative maneuvers. There is a considerable variety of normative values for esophageal high-resolution manometry depending on the equipment used and the protocols performed to obtain measurements. This should be taken into account when evaluating measurements in clinical practice and when comparing results of published research studies.

Abstract
Background: The new coronavirus disease (COVID-19) has high infection and mortality rates, and has become a pandemic. The infection and mortality rates are lower in Asian countries than in European countries. This study aimed to conduct a survey on the effects of COVID-19 on the capacity to perform gastrointestinal motility tests in Asian countries compared with European countries. Methods: We used the questionnaire previously established by our team for researchers in European countries. The correlation between the decreased rate of gastrointestinal motility and function tests, and the infection/mortality rates of COVID-19 and stringency of a government’s interventions in each country was analysed and protective measures were assessed. Results: In total, 58 gastroenterologists/motility experts in Asian countries responded to this survey. The infection/mortality rates of COVID-19 and Stringency Index had a significant impact on the testing capacity of oesophageal manometry and catheter-based pH monitoring. In European countries, most facilities used filtering facepiece 2/3 (FFP2/3) masks during oesophageal motility studies. Meanwhile, in Asian countries, most facilities used surgical masks. Conclusion: The total infection and mortality rates of COVID-19 can affect the rate of gastrointestinal motility testing and the type of protective equipment that must be used.

Influence of Acid Swallows on the Dynamics of the Upper Esophageal Sphincter. Dysphagia 2020; 36:443-455.

Abstract
Mechanisms of the upper esophageal sphincter (UES) when exposed to acid are still incompletely understood. The presented work investigated the reaction of the UES to acid exposure during swallowing. Ten healthy individuals swallowed ten 2 ml neutral water boli of pH 7, followed by 10 swallows each of different levels of acidity (pH 1.8, pH 3 and pH 5). Effects were analyzed by high-resolution manometry (HRM) for the primary parameter Restitution Time, as well as Resting Pressures, maximal, minimal pressures and time intervals. Restitution Times measured mean values of 12.67 s (SD ± 7.03 s) for pH 1.8, pH 7 = 8.69 s (SD ± 2.72 s), pH 3 = 7.56 s (SD ± 2.23 s) and pH 5 = 7.29 s (SD ± 2.55 s), showing prolonged Restitution Times in the UES when exposed to strong bolus acidity. This difference was significant towards the neutral bolus, but also to less acidic boli (pH 5: p = 0.006, pH 3: p = 0.009, pH 7: p = 0.038). Considerable differences of mean values were found for Post-Swallow Maximum and Period of Sphincter Activity. Also, Pre-Swallow Maximum values were found to be highest with the strongest acid. Relaxation Times showed a slight trend of prolongation for the highest bolus acidity. Prolonged Restitution Times may represent a reflexive protective mechanism triggered by receptors in the pharyngeal mucosa or the UES preventing regurgitation of acid into the pharynx and larynx, besides representing ongoing attempts of acid clearance. Exposure to high levels of acidity by a swallowed bolus does influence UES functions during swallowing.

Abstract
To ensure the safety of medical personnel is important during the new coronavirus infectious disease (COVID-19) pandemic. Although high-resolution manometry (HRM) is an essential device for diagnosis of functional gastrointestinal disorders, it contains risks of droplet infection, contact infection and aerosol-borne infection. Screening tests such as PCR, serology test to detect COVID-19 antibodies, and CT scan should be considered as well as body temperature check and anamnestic risk assessment. Moreover, the provision of protective equipment such as a mask with face shield (or goggles + mask), gloves, cap or hairnet, and a long-sleeved gown would be necessary to reduce the risk of COVID-19.

Abstract
Recently, there has been clinical interest in the effect of different body positions on esophageal motility. This study aimed to identify the effect of three different body positions on esophageal motility using high-resolution manometry. Thirteen healthy adults swallowed 5 mL of water in the upright, supine, and bridge positions. For the bridge position, each subject raised their waist against gravity, placed a cushion under their back, and bent their knees. The proximal contractile integral (PCI) and distal contractile integral (DCI), integrated relaxation pressure (IRP), distal latency (DL), peristaltic breaks (PBs), intrabolus pressure (IBP), and expiratory and inspiratory esophagoesophageal junction (EGJ) pressure were measured. In the bridge position, PCI, DCI, IRP, and expiratory and inspiratory EGJ pressure were significantly higher than those in the upright position (bridge PCI vs. upright PCI [p = 0.001], bridge DCI vs. upright DCI [p < 0.001], bridge IRP vs. upright IRP [p = 0.018], bridge EGJ pressure vs. upright EGJ pressure [expiratory: p = 0.001] [inspiratory: p < 0.001]). PBs were significantly shorter and DL was significantly longer in the bridge position compared to upright (bridge PBs vs. upright PBs [p = 0.001], bridge DL vs. upright DL [p = 0.001]). IBP was significantly higher in the bridge position compared to supine (bridge IBP vs. supine IBP [p = 0.01]). These results demonstrated changes in esophageal motility according to changes in position while swallowing, where esophageal contractions became stronger against gravity. Further study is required to examine the effectiveness of swallowing in the bridge position.

Abstract
BACKGROUND Functional dyspepsia (FD) and non-erosive reflux disease (NERD) are gastrointestinal disorders that often overlap. In this randomized, double-blind, placebo-controlled crossover study, the effects of adding acotiamide to treatment with proton pump inhibitors (PPI) were investigated in FD patients with heartburn who failed PPI treatment, corresponding to PPI-resistant NERD. METHODS The subjects included 16 FD patients with heartburn who failed PPI treatment, and they were administered acotiamide or a placebo for 28 days. After suspending medication for 28 days, the trial drug and placebo were crossed over and administered for 28 days. Before the study began and after each administration period, high-resolution impedance manometry (HRiM) was performed, and the modified frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire was administered. KEY RESULTS Postprandial fullness in the FD assessment and all modified FSSG items were significantly lower in the acotiamide group than in the placebo group. Esophagogastric junction pressure was significantly higher in the acotiamide group. The distal contractile integral (DCI) pressure and the highest DCI pressure both increased significantly in the acotiamide group. Moreover, in the acotiamide group, the frequency of abnormal primary peristalsis decreased to normal levels; complete bolus transit (CBT), an indicator of esophageal clearance, increased; and CBT time decreased. CONCLUSIONS & INFERENCES Acotiamide was considered to improve upper gastrointestinal functions not only in the stomach but also in the esophagus. Adding acotiamide to PPI therapy appears to improve upper abdominal symptoms in FD patients with heartburn who failed PPI treatment.

Abstract
BACKGROUND High-resolution esophageal manometry (HREM) during laparoscopic Heller myotomy (LHM) with fundoplication for achalasia allows tailoring of myotomy length and wrap tightness. The purpose of this study is to quantify long-term postoperative symptom severity and quality of life using validated questionnaires. METHODS Children ≤18 years with achalasia who previously underwent LHM with intraoperative HREM from 2010 to 2017 were prospectively surveyed. Eckardt Symptom Score (ESS), Achalasia Severity Questionnaire (ASQ), Pediatric Quality of Life Inventory (PedsQL), and Pediatric GERD Symptom and Quality of Life (PGSQ) questionnaires were administered. Scores for historical controls were obtained from prior survey instrument validation studies as comparison. RESULTS Of 30 eligible patients, 12 (40%) completed the surveys. Mean age at time of surgery was 13 ± 3 years. Assessment was performed at least 10 months after surgery with mean time elapsed of 3.6 ± 2 years. Average premyotomy lower esophageal sphincter (LES) pressure, postmyotomy LES pressure, and postfundoplication LES pressure were 30 ± 10 mmHg, 14 ± 6 mmHg, and 18 ± 9, respectively. ESS (2.3/12), ASQ (39/100 ± 16), PGSQ (symptom: 0.6/4 ± 0.4, school: 0.4/4 ± 0.4), and overall PedsQL (82/100 ± 15) were similar to those of healthy historical controls. CONCLUSION Children with achalasia undergoing LHM with intraoperative HREM had sustained long-term symptom improvement and quality of life scores comparable to healthy patients.

Abstract
GOALS This study was carried out to assess the clinical characteristics and associated systemic diseases seen in patients diagnosed with absent contractility as per the Chicago Classification version 3.0, allowing us to propose a diagnostic algorithm for their etiologic testing. BACKGROUND The Chicago Classification version 3.0 has redefined major and minor esophageal motility disorders using high-resolution esophageal manometry. There is a dearth of publications based on research on absent contractility, which historically has been associated with myopathic processes such as systemic sclerosis (SSc). STUDY We conducted a retrospective, multicenter study. Data of patients diagnosed with absent contractility were pooled from Cleveland Clinic, Cleveland, OH (January 2006 to July 2016) and Metrohealth Medical Center, Cleveland, OH (July 2014 to July 2016) and included: age, gender, associated medical conditions, surgical history, medications, and specific antibody testing. RESULTS A total of 207 patients, including 57 male individuals and 150 female individuals, with mean age of 56.1 and 60.0 years, respectively, were included. Disease distribution was as follows: SSc (diffuse or limited cutaneous) 132, overlap syndromes 7, systemic lupus erythematosus17, Sjögren syndrome 4, polymyositis 3, and dermatomyositis 3. Various other etiologies including gastroesophageal reflux disease, postradiation esophagitis, neuromuscular disorders, and surgical complications were seen in the remaining cohort. CONCLUSIONS Most practitioners use the term "absent contractility" interchangeably with "scleroderma esophagus"; however, only 63% of patients with absent contractility had SSc. Overall, 20% had another systemic autoimmune rheumatologic disease and 16% had a nonrheumatologic etiology for absent contractility. Therefore, alternate diagnosis must be sought in these patients. We propose an algorithm for their etiologic evaluation.

Abstract
Esophageal high-resolution manometry (HRM) has advanced the understanding of esophageal motor function and the ability to diagnose and manage disorders of esophageal motility. In this review, we describe the indications for and the technical performance of HRM. The Chicago classification of esophageal motor function, now in its third iteration, streamlines and standardizes the nomenclature and basic interpretation of HRM data depicted as Clouse topographic plots. In clinical practice, HRM is an important diagnostic test for patients with dysphagia as well as patients with suspected gastroesophageal reflux disease (GERD), particularly in those patients with a suboptimal symptomatic response to antisecretory therapy. HRM can support diagnoses such as achalasia, as well as provide evidence for behavioral disorders such as rumination syndrome or supragastric belching with the assistance of postprandial HRM with impedance. Further, the GERD classification of motor function introduces a three-part hierarchical evaluation of esophageal motor function in GERD, highlighting the value of assessment of esophageal contractile reserve through provocative maneuvers during HRM such as multiple rapid swallows.

Abstract
BACKGROUND lung transplantation (LTx) is a viable option for most patients with end-stage lung diseases. Esophageal motor disorders (EMD) are frequent in candidates for LTx, but there is very little data about changes in esophageal motility post-LTx. AIM the aim of our study was to assess esophageal motor disorders by high resolution manometry (HRM) both pre-LTx and six months post-LTx in patients with and without organ rejection. STUDY HRM (Manoscan®) was performed in 57 patients both pre-LTx and six months post-LTx. HRM plots were analyzed according to the Chicago classification 3.0. RESULTS EMD were found in 33.3% and in 49.1% of patients pre-LTx and post-LTx, respectively, and abnormal peristalsis was more frequently found post-LTx (p = 0.018). Hypercontractile esophagus was frequently found post-LTx (1.8% and 19.3% pre-LTx and post-LTx, respectively). Esophagogastric junction (EGJ) morphology changed significantly pre-LTx and post-LTx; type I (normal) was more frequent post-LTx (63-2% and 82.5% respectively, p = 0.007). EMD were more frequent post-LTx in both the non-rejection and rejection group, although particularly in the rejection group (43.2% and 69.2% respectively, p = 0.09). EMD such as distal spasm, hypercontractile esophagus and EGJ outflow obstruction were also observed more frequently post-LTx in the rejection group. CONCLUSION significant changes in esophageal motility were observed pre-LTx and particularly post-LTx; hypercontractile esophagus was a frequent EMD found post-LTx. EMD were more frequent in the group of patients that experienced organ rejection compared to the non-rejection group. EMD leading to an impaired esophageal clearance should be considered as an additional factor that contributes to LTx failure.

Abstract
BACKGROUND AND AIMS Patients with many different digestive diseases undergo repeated EGDs throughout their lives. Tethered capsule endomicroscopy (TCE) is a less-invasive method for obtaining high-resolution images of the GI mucosa for diagnosis and treatment planning of GI tract diseases. In this article, we present our results from a single-center study aimed at testing the safety and feasibility of TCE for imaging the esophagus, stomach, and duodenum. METHODS After being swallowed by a participant without sedation, the tethered capsule obtains cross-sectional, 10 μm-resolution, optical coherence tomography images as the device traverses the alimentary tract. After imaging, the device is withdrawn through the mouth, disinfected, and reused. Safety and feasibility of TCE were tested, focusing on imaging the esophagus of healthy volunteers and patients with Barrett's esophagus (BE) and the duodenum of healthy volunteers. Images were compared with endoscopy and histopathology findings when available. RESULTS Thirty-eight patients were enrolled. No adverse effects were reported. The TCE device swallowing rate was 34 of 38 (89%). The appearance of a physiologic upper GI wall, including its microscopic pathology, was visualized with a tissue coverage of 85.4% ± 14.9% and 90.3% ± 6.8% in the esophagus of BE patients with and without endoscopic evidence of a hiatal hernia, respectively, as well as 84.8% ± 7.4% in the duodenum. A blinded comparison of TCE and endoscopic BE measurements showed a strong to very strong correlation (r = 0.7-0.83; P < .05) for circumferential extent and a strong correlation (r = 0.77-0.78; P < .01) for maximum extent (Prague classification). TCE interobserver correlation was very strong, at r = 0.92 and r = 0.84 (P < .01), for Prague classification circumferential (C) and maximal (M) length measurements, respectively. CONCLUSIONS TCE is a safe and feasible procedure for obtaining high-resolution microscopic images of the upper GI tract without endoscopic assistance or sedation.

Abstract
Many previous studies have found that transabdominal ultrasound may allow precise measurement of gastric emptying of liquid meals. However, the clinical use of this technique has been hampered by the limitation that transabdominal ultrasound might not accurately measure gastric emptying of solid meals. It is more important to measure gastric emptying of solids instead of liquids, as gastric emptying of solids is more often delayed than gastric emptying of liquids in gastric motility disorders. Recently, transabdominal ultrasound after oral administration of a cellulose-based gastric contrast agents (TUS-OSCA) has been suggested to be effective in initial screening of gastric lesions. The aim of this study was to explore the accuracy of TUS-OSCA in the evaluation of gastric emptying of a semisolid meal. Twenty healthy young patients (10 males and 10 females aged 25.5 ± 2.5 y) were studied. Concurrent measurements of gastric emptying by scintigraphy and TUS-OSCA were performed after ingestion of 350 mL semisolid ultrasound agent labeled with 20 MBq 99mTc-sulfur colloid. There was no significant difference in the overall curves for gastric emptying time between scintigraphy and TUS-OSCA. There was a good correlation between the gastric 50% emptying times determined by scintigraphy (89.4 ± 1.8 min) and TUS-OSCA (92.5 ± 1.7 min). The correlation coefficient was r = 0.922 (p = 0.000). Current results indicate that TUS-OSCA is accurate, and the results are similar to those obtained by scintigraphy for gastric emptying of a semisolid meal.

Abstract
BACKGROUND High-resolution esophageal manometry (HREM) interpretation by the Chicago Classification (CC) derives its normal values from western volunteers using solid-state catheters. There is no normative data for the 16-channel water-perfused HREM system commonly used in India. AIMS To determine normal values for a 16-channel water-perfused HREM catheter in supine posture using healthy volunteers and substitute these normal values (if different from CC values) in the CC v3.0 algorithm. METHODS After ethics approval and informed consent, 53 volunteers (31 men) with no gastrointestinal (GI) symptoms or medications affecting GI motility underwent HREM by standard protocol. Age, gender, body mass index (BMI), and manometry parameters analyzed using Trace 1.3.3 software were collected. The median, range, and 5, 10, 75, and 95 percentiles (where applicable) were obtained for all HREM metrics. Normal value percentiles were defined as 95th (integrated relaxation pressure [IRP]), 10th-100th (distal contractile integral [DCI]), and minimum (distal latency [DL]). RESULTS The mean age was 30 years and the BMI was 24.2 kg m-2 . Compared to CC, our normal metrics were lower for IRP (13 mm Hg) and DCI (350-4500 mm Hg s cm). DCI >4500 and <70 (<5th percentile) were defined as hypercontractile and failed contraction, respectively. Abnormal DL (<4.5 s) and peristaltic break size (>5 cm) were similar to CC metrics. Applying these metrics, CC diagnoses changed in 15% (8/53) with downgrading of ineffective motility to fragmented peristalsis or normal, due to lower DCI cutoff used. CONCLUSIONS This is the first report of normative data for the 16-channel water-perfused system in supine posture. It revealed lower IRP and DCI, necessitating modification of CC cutoffs for this system.

Abstract
INTRODUCTION Swallowing difficulties, the pathophysiology behind which is incompletely understood, have been reported in 47-83% of goiter patients referred for thyroidectomy. We aimed at examining the influence of thyroid surgery on swallowing symptoms and esophageal motility. METHODS Thirty-three patients with benign nodular goiter undergoing thyroid surgery were included. All completed high-resolution esophageal manometry examinations and the goiter symptom scale score, assessed by the thyroid-specific patient-reported outcome measure. The evaluations were performed before and 6 months after surgery. RESULTS Before surgery, the goiter symptom score was median 39 points (range 2-61), which improved to median five points (range 1-52) after surgery (p < 0.001). The motility parameters were within the limits of normal swallowing physiology, both before and after surgery. Only the upper esophageal sphincter (UES) pressure increased significantly from 70.6 ± 27.7 to 87.7 ± 43.2 mmHg after surgery (p = 0.04). Using regression analyses, there was no significant correlation between change in goiter symptoms and weight of the removed goiter, motility parameters, or motility disturbances. However, patients undergoing total thyroidectomy experienced a larger reduction in pressure in the area of the UES and former thyroid gland after surgery in comparison with patients undergoing less extensive surgery. CONCLUSIONS Goiter symptoms improved significantly after thyroidectomy, but without correlation to esophageal motility disturbances. This information is essential when interpreting dysphagia in patients with nodular goiter, and when balancing patients' expectations to surgical goiter therapy.

Abstract
High-resolution manometry (HRM) and peroral endoscopic myotomy (POEM) have contributed significantly to the field of esophageal motility disorders in recent years. The development of HRM has categorized various esophageal motility disorders with a focus on a diverse range of manometric anomalies. Additionally, the Chicago classification criteria is widely used for manometric diagnosis. Moreover, POEM was introduced as a minimally invasive radical therapy for achalasia and shows promise for other spastic esophageal motility disorders as well. POEM has also enabled a transluminal endoscopic approach for determining the histology of the esophageal muscle layer, which is expected to assist in elucidating the etiology of disorders associated with esophageal motility. The purpose of this review is to update the diagnosis, pathology, and treatment of esophageal motility disorders, with a focus on the recent advances in this field.

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.

Clinicomanometric factors associated with clinically relevant esophagogastric junction outflow obstruction from the Sandhill high-resolution manometry system. Neurogastroenterol Motil 2018; 30.

Abstract
BACKGROUND Integrated relaxation pressure (IRP) is a key metric for diagnosing esophagogastric junction outflow obstruction (EGJOO). However, its normal value might be different according to the manufacturer of high-resolution manometry (HRM). This study aimed to investigate optimal value of IRP for diagnosing EGJOO in Sandhill HRM and to find clinicomanometric variables to segregate clinically relevant EGJOO. METHODS We analyzed 262 consecutive subjects who underwent HRM between June 2011 and December 2016 showing elevated median IRP (> 15 mm Hg) but did not satisfy criteria for achalasia. Clinically relevant subjects were defined as follows: (i) subsequent HRM met achalasia criteria during follow-up (early achalasia); (ii) Eckardt score was decreased at least two points without exceeding a score of 3 after pneumatic dilatation (variant achalasia); and (iii) significant passage disturbance on esophagogram without structural abnormality (possible achalasia). KEY RESULTS Seven subjects were clinically relevant, including two subjects with early achalasia, four subjects with variant achalasia, and one subject with possible achalasia. All clinically relevant subjects had IRP 20 mm Hg or above. Among subjects (n = 122) with IRP 20 mm Hg or more, clinically relevant group (n = 7) had significantly higher rate of dysphagia (100% vs 24.3%, P < .001) and compartmentalized pressurization (85.7% vs 21.7%, P = .001) compared to clinically non-relevant group (n = 115). CONCLUSIONS & INFERENCES Our results suggest that IRP of 20 mm Hg or higher could segregate clinically relevant subjects showing EGJOO in Sandhill HRM. Additionally, if subjects have both dysphagia and compartmentalized pressurization, careful follow-up is essential.

Abstract
BACKGROUND Anorectal manometry is the most commonly performed investigation for assessment of anorectal dysfunction. Findings from previous studies comparing water-perfused (WP) and solid-state (SS) techniques in the anorectum are conflicting. We compared anal sphincter pressure at rest and during dynamic maneuvers (squeezing and coughing) in healthy volunteers using SS and WP high-resolution anorectal manometry (HR-ARM) employing equivalent catheter configurations, a standardized protocol, and identical data acquisition and analysis software. METHODS Sixty healthy volunteers (40F; median age: 40; range: 18-74) underwent WP and SS HR-ARM in randomized order. Anal resting pressure, and squeeze and cough increments were measured. Median pressure and 5th and 95th percentiles were calculated for each maneuver and compared using Wilcoxon signed-rank test. Bland and Altman plots were used to assess agreement between the systems. The impact of gender and parity was also explored. KEY RESULTS Anal sphincter pressure measurements during squeeze (P<.001) and cough (P<.001) were significantly higher using SS HR-ARM than WP HR-ARM. No differences were seen at rest between the two types of catheter (nulliparous: P=.304; parous: P=.390; males: P=.167). Normal ranges for SS and WP manometry from this small group of healthy volunteers are presented. CONCLUSIONS & INFERENCES Greater sensitivity to rapid pressure change is one of the advantages associated with SS HR-ARM. This is reflected in the differences observed during dynamic maneuvers performed during this study. Catheter type should be taken into consideration when selecting normal ranges for comparison to disease states.

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.

Abstract
BACKGROUND Esophagogastric junction outflow obstruction (EGJOO) is a newly described diagnostic entity growing in importance due to the use of high resolution manometry (HRM). There is little knowledge regarding its incidence, etiopathogeny, long-term evolution, and most suitable treatment. Our objective was to increase the awareness of EGJOO to optimize the management of these patients. METHODS We conducted a historical (retrospective and prospective) study of patients diagnosed with EGJOO using HRM combined with multichannel intraluminal impedance, comparing their manometric and impedance characteristics with those of a control group. Symptoms, etiology of obstruction, acid exposure, clinical course (and its associated factors), and response to treatment were also evaluated in the EGJOO group. KEY RESULTS Forty-four subjects were included (28 patients and 16 controls). Esophagogastric junction outflow obstruction patients presented incomplete esophageal transit more frequently than controls. Patients with structural obstruction had dysphagia more frequently than patients with functional obstruction, and different manometric, impedance, and pH-metric patterns. Over one-third of the EGJOO patients presented a spontaneous resolution of symptoms without EGJOO treatment. In the multivariate analysis, the variables associated with this spontaneous symptomatic resolution included typical symptoms of gastro-esophageal reflux disease or epigastralgia as the main symptom and resting or basal pressure of the upper esophageal sphincter <50 mmHg. CONCLUSIONS & INFERENCES The majority of EGJOO patients presented intact peristalsis which may compensate for the lack of EGJ relaxation. In the EGJOO patients presenting favorable factors associated with a spontaneous resolution of symptoms, invasive treatments should be considered with special caution. Structural etiologies are more amenable to management, while the remainder may improve without intervention.

Abstract
High-resolution anorectal manometry (HR-ARM) and high-definition anorectal manometry (HD-ARM) catheters have closely spaced water-perfused or solid state circumferentially-oriented pressure sensors that provide much better spatiotemporal pressurization than non-high resolution catheters. This is a comprehensive review of HR-ARM and HD-ARM anorectal manometry catheter systems, the methods for conducting, analyzing, and interpreting HR-ARM and HD-ARM, and a comparison of HR-ARM with non-high resolution anorectal manometry. Compared to non-high resolution techniques, HR-ARM and HD-ARM studies take less time and are easier to interpret. However, HR-ARM and HD-ARM catheters are more expensive and fragile and have a shorter lifespan. Further studies are needed to refine our understanding of normal values and to rigorously evaluate the incremental clinical utility of HR-ARM or HD-ARM compared to non-high resolution manometry.

Abstract
OBJECTIVES The cause-effect relationship between bronchial asthma and gastro-esophageal reflux (GER) is known, but studies have not been able to confirm the improvement of lung function with anti-acid therapy. Hypotensive lower esophageal sphincter (LES) may lead to both acid and non-acid reflux, resulting in asthma symptoms and decreased lung function. The objectives of our study were, firstly, to compare basal LES pressure between adult patients of asthma and normal controls and, secondly, to correlate the basal LES pressure with spirometric parameters in these patients. METHODS Thirty patients, aged between 18 and 65 years, diagnosed as cases of bronchial asthma and 27 healthy controls were included in the study. All the participants were subjected to esophageal manometry after overnight fasting and basal LES pressures were recorded. Then, spirometry was done 2 h after meal and pre- and post-bronchodilator FEV1, FVC, PEFR were obtained for the asthma group. RESULTS AND CONCLUSIONS There is significant difference between basal LES pressure in patients of bronchial asthma and control population (8.70 ± 2.67 mmHg versus 16.64 ± 5.52, p < 0.0001). 66.67% of the asthma patients have reduced LES pressures (<10 mmHg). The correlation coefficient between basal LES pressure and prebronchodilator FEV1% predicted is 0.596 (p < 0.0001, 95% CI 0.3002-0.7872). Obstructive airway impairment in adult patients of bronchial asthma is associated with hypotensive LES. GER, due to hypotensive LES may contribute to deterioration of spirometric parameters in asthma patients.

Abstract
Dysphagia is a fascinating symptom. It is ostensibly simple when defined by trouble swallowing, yet its subtleties in deciphering and its variations in pathophysiology almost mandate a thorough knowledge of medicine itself. With patience and careful questioning, a multitude of various disorders may be suggested before an objective test is performed. Indeed, the ability to diligently and comprehensively explore the symptom of dysphagia is not only rewarding but also a real test for a physician who prides himself or herself on good history taking.

Abstract
BACKGROUND/AIMS The body position can influence esophageal motility data obtained with high-resolution manometry (HRM). To examine whether the body position influences HRM diagnoses in patients with esophageal dysphagia and gastroesophageal reflux disease (GERD). METHODS HRM (Manoscan) was performed in 99 patients in the sitting and supine positions; 49 had dysphagia and 50 had GERD as-sessed by 24-hour pH monitoring. HRM plots were analyzed according to the Chicago classification. RESULTS HRM results varied in the final diagnoses of the esophageal body (EB) in patients with dysphagia (P = 0.024), the result being more distal spasm and weak peristalsis while sitting. In patients with GERD, the HRM diagnoses of the lower esophageal sphinc-ter (LES), the esophagogastric junction (EGJ) morphology, and EB varied depending on the position; (P = 0.063, P = 0.017, P = 0.041 respectively). Hypotensive LES, EGJ type III (hiatal hernia), and weak peristalsis were more frequently identified in the sitting position. The reliability (kappa) of the position influencing HRM diagnoses was similar in dysphagia and GERD ("LES diagnosis": dysphagia 0.32 [0.14-0.49] and GERD 0.31 [0.10-0.52], P = 0.960; "EB diagnosis": dysphagia 0.49 [0.30-0.69] and GERD 0.39 [0.20-0.59], P = 0.480). The reliability in "EGJ morphology" studies was higher in dysphagia 0.81 (0.68-0.94) than in GERD 0.55 (0.37-0.73), P = 0.020. CONCLUSIONS HRM results varied according to the position in patients with dysphagia and GERD. Weak peristalsis was more frequently diagnosed while sitting in dysphagia and GERD. Hypotensive LES and EGJ type III (hiatal hernia) were also more frequently diagnosed in the sitting position in patients with GERD.

Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) was introduced as a new effective therapeutic option for esophageal achalasia. METHOD A total of 112 achalasia patients categorized into three subtypes by HRM who underwent POEM were enrolled in our study. Eckardt score and HRM were performed preoperation, 6 months, and 1 year after POEM to evaluate the effectiveness, safety, and feasibility of POEM and to investigate the treatment response to POEM for the three subtypes of achalasia, classified by high-resolution manometry (HRM). RESULTS POEM was successfully performed in all patients. Compared with pre-POEM scores, the Eckardt scores were significantly reduced from 7.3 ± 1.4 to 1.0 ± 0.8 6 months after POEM and to 1.2 ± 0.6 1 year after POEM (p < 0.05). The LESP before treatment was 41.8 ± 15.3 mmHg, compared with a LESP of 18.4 ± 7.1 mmHg 6 months after POEM and 20.7 ± 7.5 mmHg 1 year after POEM (p < 0.05). In addition, POEM decreased the 4-s IRP from 33.4 ± 9.0 to 14.6 ± 3.8 mmHg 6 months after POEM and to 16.4 ± 3.9 mmHg 1 year after POEM (p < 0.05). The 4-s IRP was reduced to <15 mmHg in 64 of 112 patients. Type II had the best response to POEM, while type III exhibited the worst response. CONCLUSIONS POEM appears to be an effective and less invasive treatment for achalasia. HRM can be useful in the classification of achalasia, while these subclassifications help to predict the responsiveness to POEM.

Abstract
BACKGROUND Esophageal high-resolution manometry (HRM) has rapidly gained much popularity worldwide. The Chicago Classification for esophageal motility disorders is based on a set of normative values for key metrics that was obtained using one of the commercially available HRM systems. Thus, it is of great importance to evaluate whether these normative values can be used for other HRM systems as well. PURPOSE In this review, we describe the presently available HRM systems, the currently known normative thresholds and the factors that influence them, and assess the use of these thresholds. Numerous factors including the type of HRM system, demographic factors, catheter diameter, body position during testing, consistency of bolus swallows, and esophageal length have an influence on the normative data. It would thus be ideal to have different sets of normal values for each of these factors, yet at the moment the amount of normative data is limited. We suggest broadening the normal range for parameters, as this would allow abnormal values to be of more significance. In addition, we suggest conducting studies to assess the physiological relevance of abnormal values and stress that for each system different normative thresholds may apply.

Abstract
BACKGROUND The Chicago classification for esophageal motility disorders was designed for a 36-channel manometry system with sensors spaced at 1 cm. However, many motility laboratories outside the USA use catheters with a lower resolution in the segments outside the esophagogastric junction. Our aim was to investigate the effect of spatial resolution on the Chicago metrics and diagnosis. METHODS In 20 healthy volunteers and 47 patients with upper gastrointestinal symptoms, high-resolution manometric studies of the esophagus were retrospectively reanalyzed using the original 1-cm spacing in the segments outside the 7-cm esophagogastric junction segment, and again after manually increasing the spacing between sensors to 2, 3, and 4 cm (above the lower esophageal sphincter region). Measurements were analyzed in random order and the investigator was blinded to the outcome of the analyses performed in another resolution of the same patient. Intra-class correlation coefficients (ICC) and Kappa values were determined. KEY RESULTS There was a very strong correlation between the 1-cm and 2-cm analysis for all Chicago metrics studied in healthy volunteers (ICCs: distal contractile integral 0.998; contractile front velocity (CFV) 0.964; distal latency 0.919; peristaltic break size 0.941). The 2-cm spacing analysis also correlated very well with the 1-cm analysis for the different Chicago diagnoses obtained in the patients (Kappa values ranging from 0.665 to 1.000). When the sensor spacing was increased to 3 and 4 cm, the correlation was reduced to moderate for the Chicago metrics, especially for break size and CFV of peristalsis. CONCLUSIONS & INFERENCES The Chicago classification for esophageal motility disorders is still valid and the same normal values can be used when catheters with a slightly lower resolution are used (i.e., 2-cm vs 1-cm spacing). For larger sensor intervals, the classification and the normal values will need to be adjusted.

Abstract
BACKGROUND Transient lower esophageal sphincter relaxation (TLESR) is a vagally mediated reflex that occurs most frequently after a meal. Cardiac vagal tone (CVT) decreases after a meal, and correlates with changes in gastric electrical activity. Furthermore, decreased CVT has been reported in patients with gastro-esophageal reflux disease. We therefore aimed to characterize the association between postprandial changes in CVT and the occurrence of TLESR and reflux. METHODS Ten healthy volunteers underwent simultaneous autonomic nervous system, gastric myoelectric activity, lower esophageal-sphincter pressure, and reflux monitoring for 30 min in the fasting state, followed by a standard meal, and a further 4 h postprandially. Results are in mean ± SEM. KEY RESULTS The number of TLESRs (P < 0.0001) and reflux episodes (P < 0.0001) increased after the meal, while CVT decreased (P < 0.01). Cardiac sensitivity to baroreceptor reflex (CSB) showed similar time course changes to CVT (P = 0.06). During the first postprandial hour there was a strong correlation between the number of TLESRs and reflux episodes with CVT (R(2) = 0.51 and R(2) = 0.50, respectively; P < 0.05). There was also an increase in the dominant power and power ratio on electrogastrography (P < 0.05) after the meal. CONCLUSIONS & INFERENCES In healthy volunteers, the increase in the number of TLESRs and reflux episodes after a meal occurred mostly at a time of reduced CVT. Further studies should explore whether modulation of CVT can modify frequency of TLESRs and also this relationship should be further explored in patients with reflux disease.

Abstract
BACKGROUND Esophageal high-resolution manometry (HRM) is a novel method to assess esophageal motility. Several software and hardware systems are currently available. A set of normal values for HRM parameters was established in the US, using proprietary tactile-sensing catheter technology (Given Imaging). We wished to determine normal values for HRM performed with another type of catheter (Unisensor). METHODS Fifty-two healthy volunteers underwent supine HRM. Each subject swallowed 10 liquid water boluses. Esophageal contraction parameters were evaluated and normal values were calculated (defined as 5th and 95th percentile of values). KEY RESULTS The normal range for the following parameters was calculated; distal contractile integral (mean 1319.44, with a 5-95th percentile range [185.65-3407.60]), contractile front velocity (mean 3.98, 5-95th percentile range [2.40-6.50]), Intrabolus pressure (mean 9.68, range [1.00-19.00]), contraction amplitude measured 5 cm above the esophagogastric junction (EGJ; mean 78.76, range [23.00-146.00]), contraction amplitude 15 cm above the EGJ (mean 43.66, range [3.60-96.00]), transition zone (TZ) length (mean 1.34, range [0.00-5.63]), upper esophageal sphincter (UES) pressure (mean 81.63, range [19.50-165.10]), EGJ length (mean 2.97, range [2.17-4.00]), EGJ resting pressure (mean 29.35, range [8.95-51.40]), EGJ relaxation pressure (mean 16.79, range [1.00-39.35]), IRPs4 (mean 13.42, range [2.59-28.28]), and gastric pressure (mean 5.06, range [0.00-9.46]). CONCLUSIONS & INFERENCES Overall, the normal values of esophageal HRM parameters obtained with the Unisensor catheter resemble those of the previously published series. Marked differences in upper limits of normal were found for parameters related to the esophageal sphincters and TZ length. Users of HRM should be aware of these differences and define pathology based on comparison to appropriate normal values.

Abstract
Disorders of gastrointestinal motility are frequently seen in clinical practice. Apart from motility disorders, factors leading to lowered visceroperception thresholds are recognized as commonly involved in the pathogenesis of functional gastrointestinal disorders. The wide array of gastrointestinal motility and viscerosensitivity tests available is in contrast with the relatively limited number of tests used universally in clinical practice. The main reason for this discrepancy is that the outcome of a test only becomes truly important when it carries clinical consequences. The main goal of this Review is to assess the place of the presently available gastrointestinal motility and sensitivity tests in the clinical armamentarium of the gastroenterologist.

Abstract
The introduction of high-resolution manometry (HRM) has been a significant advance in esophageal diagnostics. Normative values however are currently based upon a single set of published reference values, and multiple new metrics have been added over the past several years. Our goal was to provide a second set of 'normal-values' and to include all current metrics suggested by the 2012 Chicago classification. Sixty-eight subjects without foregut symptoms or previous surgery (median age 25.5 years, ranging from 20-58 years, 53% female) underwent esophageal motility assessment via an established standardized protocol. Normative thresholds were calculated for esophago-gastric junction (EGJ) characteristics (resting, relaxation, intrabolus pressure, and lengths) as well as for esophageal body strength (contraction amplitudes at multiple levels, distal contractile integral, integrity of peristalsis) and wave propagation (contractile front velocity, distal latency). Overall, our findings where strikingly similar to the previously described metrics derived from 75 control subjects of the Northwestern group. This suggests a high degree of reproducibility of HRM.

Abstract
Background To compare the characteristics between 22-channel water-perfusion manometry (WPM) and solid-state manometry (SSM) with 36 sensors of the pressure measurements, as well as patients’ discomfort indices in nose and pharynx, the preparation and operation time of the manometry. Methods 12 volunteers were included in the study. Each of the volunteers underwent esophageal manometry by both 22-channel water-perfusion catheter (WPC) and solid-state catheter (SSC) with 36 sensors in random order, and separated by 30 min. The subjects gave a VAS score soon after each test. Non-parametric tests were used to analyze the differences and Bland-Altman plots were used to assess the consistency of the two systems. Results During the wet swallows, there were significant differences between the two systems in three measurements of location of lower esophageal sphincter (LES) upper margin (Z = -2.11, P = 0.035), LES relax ratio (Z = -2.20, P = 0.028) and IRP4s (Z = -2.05, P = 0.041). During the jelly pocket swallows, LES relax ratio measurements of the two systems showed significant differences (Z = -2.805, P = 0.005). Further Bland–Altman plots analysis presented good agreement between the two systems measurements of location of LES upper margin, LES relax ratio and IRP4s. The discomfort indices of subjects’ nasal sensation were higher when inserting the solid-state catheter [5(3.75-5)] than water-perfusion one (2.5(2-4)) (Z = -2.471, P = 0.013), as well as the discomfort indices of pharyngeal sensation (7.5(4.75-9) vs. 4.5(3.75-6.5)), (Z = -2.354, P = 0.019). The preparation time for WPC was 40(39-41) minutes, which was much longer than that for SSC 32.5(31.75-33) minutes, (Z = -3.087, P = 0.002). And the nurses reported it’s much easier to insert WPC (Z = -3.126, P = 0.002). Conclusions In conclusion, most pressure measurements were consistent between WPM and SSM. Patients tolerated better with WPC, while for operators, the SSC presented more convenient.
