Impact of Surgical Intervention on Nonobstructive Dysphagia: A Retrospective Study Based on High-Resolution Impedance Manometry in a Taiwanese Population at a Single Institution. J Pers Med 2022; 12:590. [PMID: 35455706 PMCID: PMC9025219 DOI: 10.3390/jpm12040590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Revised: 03/30/2022] [Accepted: 03/31/2022] [Indexed: 02/04/2023] Open
Abstract
Esophageal motility disorders account for a large proportion of nonobstructive dysphagia cases, which constitute a heterogeneous group of diagnoses that commonly result in peristaltic derangement and impaired relaxation of the lower esophageal sphincter. We performed a single-institution retrospective study enrolling consecutive patients with chief complaints of dysphagia who underwent HRIM from December 2014 to December 2019, and analyzed demographic, clinical, and manometric data using descriptive statistics. In total, 277 identified patients were included in the final analysis. Ineffective esophageal motility (n = 152, 24.5%) was the most common diagnosis by HRIM, followed by absent contractility, EGJ outflow obstruction, type II achalasia, and type I achalasia. Furthermore, surgery including exploratory, laparoscopic, and robotic myotomy, as well as POEM, is considered the most effective treatment for patients with non-spastic achalasia and EGJOO, due to its effective symptom palliation and prevention of disease progression; surgery also contributes to an obvious improvement of dysphagia compared with slightly less efficacy for other related symptoms. Our study aimed to elaborate the clinical characteristics of patients with nonobstructive dysphagia based on HRIM in a Taiwanese population, and to analyze the therapeutic outcomes of such patients who ultimately underwent surgical interventions.

Behavioral therapy is superior to follow-up without intervention in patients with supragastric belching-A randomized study. Neurogastroenterol Motil 2022; 34:e14171. [PMID: 33991432 DOI: 10.1111/nmo.14171] [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: 01/30/2021] [Revised: 04/13/2021] [Indexed: 12/10/2022]
Abstract
BACKGROUND Behavioral therapy (BT) has been proven effective in the treatment of supragastric belching (SGB) in open studies. The aim was to compare BT to follow-up without intervention in patients with SGB in a randomized study. METHODS Forty-two patients were randomized to receive 5 sessions of BT, comprising diaphragmatic breathing exercises, or to follow-up without intervention. Patients were evaluated at 6 months, at which point the control group was also offered BT and evaluated after another 6 months. The frequency and intensity of belching and mental well-being were evaluated with a visual analog scale (VAS). Depression, anxiety, and health-related quality of life (HRQoL) were evaluated with four questionnaires: BDI, BAI, 15D, and RAND-36. KEY RESULTS The frequency and intensity of SGB were significantly lower in the therapy group (n = 19) than in the control group (n = 18) at the 6-month control (p < 0.001). When all patients (n = 36) were evaluated 6 months after BT, in addition to relief in the frequency and intensity of belching (p < 0.001), mental well-being had also improved (p < 0.05). Of all 36 patients, 27(75%) responded to BT. Depression scores were lower after therapy (p < 0.05). Only minor changes occurred in anxiety and HRQoL. CONCLUSIONS AND INFERENCES Behavioral therapy is superior to follow-up without intervention in patients with SGB in reducing belching and depression; it also improves mental well-being but has only a modest effect on anxiety and HRQoL.

Impact of patient position on esophageal motility disorders using high-resolution esophageal manometry with impedance (HREMI): supine versus upright swallows. Esophagus 2021; 18:880-888. [PMID: 33974190 DOI: 10.1007/s10388-021-00849-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Accepted: 04/29/2021] [Indexed: 02/03/2023]
Abstract
BACKGROUND High-resolution esophageal manometry with impedance (HREMI) performed with supine patient positioning is used to evaluate patients for esophageal dysmotility. However, most patients experience symptoms related to esophageal dysmotility when eating or drinking upright. The aims of this study are to: (1) compare HREMI metrics in supine versus upright position; and (2) determine if upright position alters motility characterization of patients. METHODS HREMI of twelve wet swallows in supine position and five wet swallows in upright position were performed on normal subjects (NS) and consecutive patients. Chicago Classification v3.0 (CC) diagnoses were evaluated in the supine position and a modified version of the Chicago Classification system was used in the upright position using normative upright values for DCI and IRP. RESULTS DCI decreased in NS by 414 mmHg × cm × sec (p = 0.001) and patients by 613 mmHg × cm × sec (p < 0.001). IRP decreased in NS by 6.2 mmHg (p < 0.001) and patients by 4.6 mmHg (p < 0.001). The rate of successful bolus clearance decreased in the upright position in patients by 11% (p < 0.001), but no statistically significant differences were observed in NS. 82 of 200 patients (41%) had a change in CC diagnosis in the upright position. Bolus clearance in the upright position varied in patients depending on their diagnosis in the upright position. CONCLUSIONS Upright swallows had lower LES, IRP, DCI and UES pressures in both normal subjects and patients with decreased bolus clearance in patients. Upright positioning can alter esophageal motility patterns and enhance diagnostic yield. Thus, upright swallows supplement supine swallows to help characterize esophageal dysmotility.

Abstract
BACKGROUND AND AIM Variations in the Chicago 3.0 normative metrics may exist with different postures and with different provocative swallow materials in a healthy Asian population. METHOD Eligible healthy Malay volunteers were invited to undergo the high-resolution esophageal manometry (inSIGHT Ultima, Diversatek Healthcare, Milwaukee, WI, USA). In recumbent and standing positions, test swallows were performed using liquid, viscous, and solid materials. Metrics including integrated relaxation pressure 4 s (IRP-4 s, mmHg), distal contractile integral (DCI, mmHg s cm), distal latency (DL, s), and peristaltic break (PB, cm) were reported in median and 95th percentile. RESULTS Fifty of 57 screened participants were recruited, and 586 saline, 265 viscous, and 261 solid swallows were analyzed. Per-patient wise, in the recumbent position, 95th percentile for IRP-4 s, DCI, DL, and PB were 16.5 mmHg, 2431 mmHg s cm, 8.5 s, and 7.2 cm, respectively. We observed that with each posture, the use of viscous swallows led to changes in DL, but the use of solid swallows led to more changes in the metrics including DCI and length of PB. Compared with a recumbent posture, anupright posture led to lower IRP-4 s and DCI values. Both per-patient analysis and per-swallow analyses yielded almost similar results when comparing the different postures and types of swallows. No major motility disorders were observed in this cohort of asymptomatic population. However, more motility disorders were reported in the upright position. CONCLUSIONS Variations in metrics can be observed in different postures and with different provocative swallow materials in a healthy population. The normative Chicago 3.0 metrics are also determined for the Malay population.

Abstract
Background: Non-cardiac chest pain is common with two-thirds due to gastroesophageal reflux disease (GERD). Objective: To evaluate the effectiveness and safety of guided vs. empirical therapy in non-cardiac chest pain. Methods: Adults with normal angiogram or stress test were randomized into either a guided or empirical group. In the guided group, after the ambulatory pH-impedance test, if GERD then dexlansoprazole 30 mg/day for 8 weeks, but if functional or hypersensitive chest pain, then theophylline SR 250 mg/day for 4 weeks. In the empirical group, dexlansoprazole 60 mg/day was given for 2 weeks. The primary outcome was global chest pain visual analog score (VAS) and secondary outcomes were Quality of Life in Reflux and Dyspepsia (QOLRAD), GERD questionnaire (GERDQ), and pH parameters, all determined at baseline, 2nd and 8th weeks. Results: Of 200 screened patients, 132 were excluded, and of 68 randomized per-protocol, 33 were in the guided group and 35 in the empirical group. For between-group analysis, mean global pain scores were better with guided vs. empirical group at 8th week (P = 0.005) but not GERDQ or QOLRAD or any of pH measures (all P > 0.05). For within-group analysis, mean QOLRAD improved earliest at 8th week vs. baseline (P = 0.006) in the guided group and 2nd week vs. baseline (P = 0.011) in the empirical group but no differences were seen in other secondary outcomes (P > 0.05). No serious adverse events were reported. Conclusions: Guided approach may be preferred over short-term empirical therapy in symptom response, however QOLRAD, acid-related symptoms, or pH measures are not significantly different (trial registration ID no. NCT03319121).

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

New Swallowing Method to Improve Pharyngeal Passage of a Bolus by Creating Negative Pressure in the Esophagus-Vacuum Swallowing. Am J Phys Med Rehabil 2019; 97:e81-e84.

Abstract
Supplemental digital content is available in the text. Herein, we present a case of a patient with Wallenberg syndrome with severe bulbar dysphagia who discovered a unique swallowing method: creating strong negative pressure in the esophagus to improve pharyngeal passage of a bolus. A 47-yr-old man presented with a subarachnoid hemorrhage secondary to a ruptured aneurysm in the right vertebral artery. After coil embolization, he experienced severe dysphagia due to Wallenberg syndrome and required tube feeding. Eighty-one days after the onset of the stroke, a videofluoroscopic swallowing evaluation revealed that the bolus was rapidly sucked into the esophagus. High-resolution manometry showed weak constriction of the pharynx simultaneous with forced, voluntary constriction of the diaphragm before swallowing; this created negative pressure in the esophagus. The authors named this unique swallowing method “vacuum swallowing.” Ultimately, the patient was able to eat an ordinary diet via the use of this technique. Vacuum swallowing is a unique method of improving pharyngeal passage of a bolus by creating strong negative pressure in the esophagus. Additional studies are necessary to determine whether vacuum swallowing can be successfully used for other forms of dysphagia.

Abstract
Secondary peristalsis contributes to the clearance of the refluxate from the esophagus. Acute administration of 5-hydroxytryptamine 4 (5-HT4 ) receptors agonist, mosapride or esophageal infusion of hydrochloric acid (HCl) facilitates secondary peristalsis. The aim of this study was to determine whether esophageal acid infusion and administration of mosapride had different effects on secondary peristalsis. Secondary peristalsis was performed with esophageal distension with rapid and slow air injections in 16 healthy subjects. We performed two separate sessions with HCl (0.1 N) and 40 mg oral mosapride to compare their influence on secondary peristaltic parameters. The threshold volume of secondary peristalsis was significantly lower with HCl infusion than mosapride (P = 0.01) by slow air injections. The threshold volume to generate secondary peristalsis was significantly lower with HCl infusion than mosapride (P = 0.002) by rapid air injections. More secondary peristalsis was trigged by rapid air injections after HCl infusion than mosapride (P = 0.003). Infusion of HCl or mosapride administration has similar effects on peristaltic wave amplitude and duration of primary and secondary peristalsis. Acute esophageal acid infusion can induce greater mechanosensitivity to distension-induced secondary peristalsis than 5-HT4 receptors agonist mosapride. The data suggest that acid-sensitive afferents are more likely to contribute to sensory modulation of esophageal secondary peristalsis; however, the motility aspects of secondary peristalsis are comparable between acute esophageal acidification and 5-HT4 receptors activation via mosapride.

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

Abstract
The utilization of high-resolution manometry (HRM) has enhanced our understanding and assessment of esophageal motor disorders. Moreover, the combination of impedance technology with HRM (HRIM) has further improved our knowledge of esophageal physiology and the clinical evaluation of dysmotility, thanks to the addition of accurate measurement of bolus transit. Areas covered. This paper provides an overview of current knowledge in the use of HRIM for the study of esophageal functional disorders by reporting mainly the results of many publications and several systematic reviews in this field. Expert opinion. HRIM has represented a relevant improvement in the assessment of esophageal motility and has required the development of new metrics, such as the esophageal impedance integral ratio, the bolus flow time, the nadir impedance pressure and the impedance bolus height, which increase the evaluation of esophageal bolus transit. An extension of impedance is represented by functional lumen imaging probe (FLIP), which determines the biophysical properties and the distensibility of the esophagus and permits to detect contractility patterns not seen on HRM alone. We eagerly wait for a new and fruitful iteration of the Chicago Classification, now in version 3.0, which can cover the ongoing clinical experience of HRIM.

Dig Dis Sci 2019; 64:811-814. [PMID: 30535781 DOI: 10.1007/s10620-018-5384-x] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Accepted: 11/15/2018] [Indexed: 12/20/2022]
Abstract
BACKGROUND Ineffective esophageal motility (IEM) is defined as a distal contractile integral < 450 mmHg/s/cm in at least 50% of ten liquid swallows on high-resolution esophageal manometry (HREM). Whether this latest definition correlates with degree of symptoms has not been studied. METHODS Patients presenting for HREM prospectively rated their symptoms using the Eckardt score. Topography plots were retrospectively reviewed and classified according to the latest Chicago Classification. Patients with non-obstructive dysphagia and an Eckardt score of at least 1 were included. Patients with major motility disorders were excluded. Scores between patients with IEM (group A) and patients with normal classification (group B) were compared using two-tailed t-tests. Spearman's correlation coefficient was calculated to determine correlation between symptoms and percent bolus clearance. RESULTS A total of 241 patients were screened; 33 patients met criteria for group A and 44 patients for group B. There was no difference between the two groups in mean symptom severity for dysphagia (1.63 vs. 1.61, P = 0.89), chest pain (0.67 vs. 0.75, P = 0.64), regurgitation (1.06 vs. 0.85, P = 0.32), or weight loss (0.85 vs. 0.49, P = 0.11). The percent bolus clearance was significantly lower in group A (46.5% vs. 76.7%, P > 0.01). There was a moderate inverse correlation between dysphagia and percent bolus clearance (R = - 0.37) in group A, but none in group B (R = 0.09). CONCLUSION The classification of IEM did not discriminate from normal studies for symptom severity in our cohort. However, patients with IEM did have an inverse correlation between dysphagia score and bolus clearance, but those without IEM did not. Adding impedance information to the motor pattern classification should be considered in the symptom assessment in minor motility disorders.

Abstract
Purpose Pharyngeal high-resolution manometry is an emerging practice for diagnosis of swallowing disorders in the upper aerodigestive tract. Advancement of a catheter through the upper esophageal sphincter may introduce safety considerations. There are no published studies of catheter placement complications, side effects, or tolerability. This study examines patient-reported side effects and tolerability of pharyngeal high-resolution manometry. Method Data were collected prospectively from 133 adult patients who underwent pharyngeal high-resolution manometry for the 1st time. Patients rated tolerability specific to "nose" and "throat" using a visual analog scale for 4 procedure time points: catheter passage, during the procedure, catheter removal, and after the procedure. Complications during catheter passage and removal were recorded. A telephone call was placed to the patient within 6 days to survey side effects experienced after the procedure. Results The patient sample was composed of 91 males and 42 females with a mean age of 66 years ( SD = 14.4). Tolerability scores for catheter passage showed no significant difference ( p = .7288) in the nose versus throat. Tolerability for females was significantly less ( p = .0144) than that for males. Participants with the shortest procedure duration showed greatest discomfort in the nose ( p = .0592) and throat ( p = .0286). Complications included gag response (14%), emesis (2%), and epistaxis (< 1%). Side effects included sore throat (16%), nose discomfort (16%), coughing (11 %), nosebleed (4%), and nausea/vomiting (4%). Conclusions High-resolution manometry appears to have high patient tolerability with low incidence of side effects. Rates of complications and side effects are similar to those reported for other transnasal procedures.

Abstract
Background/Aims Swallows with viscous or solid boluses in different body positions alter esophageal manometry patterns. Limitations of previous studies include lack of standardized viscous substrates and the need for chewing prior to swallowing solid boluses. We hypothesize that high-resolution impedance manometry (HRiM) using standardized viscous and super-viscous swallows in supine and upright positions improves sensitivity for detecting esophageal motility abnormalities when compared with traditional saline swallows. To establish normative values for these novel substrates, we recruited healthy volunteers and performed HRiM. Methods Standardized viscous and super-viscous substrates were prepared using “Thick-It” food thickener and a rotational viscometer. All swallows were administered in 5-mL increments in both supine and upright positions. HRiM metrics and impedance (bolus transit) were calculated. We used a paired two-tailed t test to compare all metrics by position and substrate. Results The 5-g, 7-g, and 10-g substrates measured 5000, 36 200, and 64 700 mPa sec, respectively. In 18 volunteers, we observed that the integrated relaxation pressure was lower when upright than when supine for all substrates (P < 0.01). The 10-g substrate significantly increased integrated relaxation pressure when compared to saline in the supine position (P < 0.01). Substrates and positions also affected distal contractile integral, distal latency, and impedance values. Conclusions We examined HRiM values using novel standardized viscous and super-viscous substrates in healthy subjects for both supine and upright positions. We found that viscosity and position affected HRiM Chicago metrics and have potential to increase the sensitivity of esophageal manometry.

Modern diagnosis of GERD: the Lyon Consensus. Gut 2018; 67:1351-1362.

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

Abstract
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 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
OBJECTIVES To study esophageal high resolution manometry (HRM) in systemic sclerosis (SSc) patients and the correlation of findings to The University of California, Los Angeles Scleroderma Clinical Trials Consortium gastrointestinal tract 2.0 (UCLA SCTC_GIT 2.0). METHODS Forty SSc patients were administered to the UCLA SCTC GIT 2.0. Patients underwent HRM study (Solar GI MMS). HRM data were compared with 15 healthy volunteers. RESULTS Forty patients with mean age 46 ± 7 years and disease duration 9.3 ± 7 years reported upper (85.7%), lower GI symptoms (75%), while 5% reported no symptoms. Mean ± SD scores of UCLA SCTC_GIT 2.0 items were as follows: reflux 1.2 ± 0.8, distention 1.6 ± 1.2, fecal soiling 0.3 ± 0.9, diarrhea 0.8 ± 1, social 1 ± 1, emotional 1 ± 1.1, constipation 0.5 ± 0.9, and total GIT score 0.9 ± 0.6. Lower esophageal sphincter (LES) pressure and distal esophageal amplitude were significantly lower in SSc patients than controls. Main manometric findings were decreased LES resting pressure (40%) and aperistalsis (40%). Regression analyses showed distal esophageal amplitude and LES resting pressure negatively correlated with reflux score (r = -0.64; p = 0.001 and r = -0.46; p = 0.019, respectively), and total GIT score (r = -0.54; p = 0.007 and r = -0.42; p = 0.03, respectively). LES resting pressure had negative correlations with diarrhea score (r = -0.062; p = 0.002). CONCLUSIONS Decreased distal esophageal amplitude encountered as hypoperistalsis or even aperistalsis was associated with increased reflux and GIT scores (negatively correlated) UCLA SCTC_GIT 2.0 questionnaires. The GIT2.0 is easy to use and can serve as an indicator that further testing of the GI tract, including the esophagus, is indicated.

Abstract
OBJECTIVE Nocturnal gastroesophageal reflux (nGER) has been associated with respiratory diseases. Our aim was to study a questionnaire method to identify nGER subjects with respiratory involvement in a general population. MATERIAL AND METHODS A subgroup of Icelandic participants in the European Community Respiratory Health Survey III (ECRHS III) reporting symptoms of nGER (n = 48) as well as age and gender paired controls (n = 42) were studied further by a structured interview, questionnaires, laryngeal fibrescopy, and exhaled breath condensate. A subgroup underwent 24-h oesophageal pH impedance (24-h MII-pH) measurements. Symptoms of nGER were assessed with a modified version of the reflux disease questionnaire (RDQ), where symptoms were divided into daytime and nocturnal. A report of nGER both at baseline and at follow-up was defined as persistent nGER. RESULTS Participants reporting persistent nGER had significantly more signs of laryngopharyngeal reflux according to the reflux finding score than those without nGER (Mean ± SD: 5.1 ± 2.3 vs. 3.9 ± 2.2, p = 0.02). Of the 16 persistent nGER subjects that underwent 24-h MII-pH, 11 had abnormal gastroesophageal reflux, but none of three control subjects (69% vs. 0%). Pepsin was more commonly found in exhaled breath condensate in the nGER group (67% vs. 45%, p = 0.04). CONCLUSIONS Participants with nGER symptoms at least once a month, reported on two occasions, had a high level of positive 24-h MII-pH measurements, laryngeal inflammation and pepsin in exhaled breath condensate. This nGER definition identified a representable group for studies on nGER and respiratory diseases in a general population.

Abstract
Objective Acute administration of 5-hydroxytryptamine4 (5-HT4) receptor agonist, mosapride or esophageal infusion of the transient receptor potential vanilloid receptor-1 (TRPV1) agonist capsaicin promotes secondary peristalsis. We aimed to investigate whether acute esophageal instillation of capsaicin-containing red pepper sauce or administration of mosapride has different effects on the physiological characteristics of secondary peristalsis. Methods Secondary peristalsis was induced with mid-esophageal air injections in 14 healthy subjects. We compared the effects on secondary peristalsis subsequent to capsaicin-containing red pepper sauce (pure capsaicin, 0.84 mg) or 40 mg oral mosapride. Results The threshold volume for generating secondary peristalsis during slow air distensions was significantly decreased with capsaicin infusion compared to mosapride (11.6 ± 1.0 vs. 14.1 ± 0.8 mL, P = 0.02). The threshold volume required to produce secondary peristalsis during rapid air distension was also significantly decreased with capsaicin infusion (4.6 ± 0.5 vs. 5.2 ± 0.6 mL, P = 0.02). Secondary peristalsis was noted more frequently in response to rapid air distension after capsaicin infusion than mosapride (80% [60–100%] vs. 65% [5–100%], P = 0.04). Infusion of capsaicin or mosapride administration didn’t change any parameters of primary or secondary peristalsis. Conclusions Esophageal infusion with capsaicin-containing red pepper sauce suspension does create greater mechanosensitivity as measured by secondary peristalsis than 5-HT4 receptor agonist mosapride. Capsaicin-sensitive afferents appear to be more involved in the sensory modulation of distension-induced secondary peristalsis.

Abstract
The aim of this study was to investigate the normal high-resolution manometry and impedance (HRiM) values in the supine and sitting positions in the population of Northern China, and to investigate the influence of different body positions and bolus consistency on esophageal HRiM findings. In this study, healthy volunteers in the supine position underwent esophageal HRiM examination of 10 swallows of 5 mL normal saline solution and 10 swallows of 5 mL synthetic gel of known viscosity, and in the sitting position of an additional five swallows of a synthetic gel of known viscosity. Total bolus transit time (TBTT), complete bolus transit rate (CBTR), distal contractile integral (DCI), distal esophageal amplitude (DEA), and integrated relaxation pressure (IRP) were measured. Sixty-two healthy volunteers were examined in the supine position and 45 of these performed additional swallows of the viscous gel in the sitting position. In the supine position, normal values for swallowing the liquid and viscous boli were as follows: TBTT 6.9 ± 0.9 and 8.0 ± 1.2 s (P < 0.001), CBTR 90.3 ± 14.0 and 77.9 ± 20.3% (P < 0.001), DCI 1891.5 ± 1131.9 and 1967.8 ± 1140.1 mmHg.s.cm (P = 0.227), DEA 95.3 ± 35.4 and 98.7 ± 37.5 mmHg (P = 0.148), and IRP 10.4 ± 4.9 and 9.0 ± 4.2 mmHg (P < 0.001), respectively. For swallows of the viscous boli in the sitting position, TBTT, DCI, DEA, and IRP were significantly decreased, while CBTR was unchanged (P = 0.075). Normal HRiM values of the population of Northern China were established. Esophageal transit times of viscous boli were significantly slower, more often incomplete and produced less normal peristalsis in the supine position than swallows of liquid boli. Independent reference values for different manometric systems, body positions, and population need to be established before clinical application.

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
Objective. To investigate the esophageal function tests in British and Chinese patients with gastroesophageal reflux disease (GERD). Methods. Patients with GERD were selected from the functional gut clinic, London, and digestive department, Beijing Chao-Yang Hospital, after taking the examinations of High-resolution Manometry and Impedance (HRiM) and 24-hour Multi-Channel Intraluminal Impedance and pH Recording (MII/pH) between 2013 and 2014. Chinese healthy volunteers who undertook HRiM were also selected as control group. Results. Fifty-nine British and 82 Chinese patients with GERD and 62 Chinese healthy volunteers were entered. Values for British patients, Chinese patients, and healthy volunteers were as follows: Lower esophageal sphincter pressure (LESP) 16.0 ± 8.6, 16.5 ± 10.0, and 26.4 ± 10.9 mmHg, peristalsis (normal/small break/large break) 24/12/23, 44/10/28, and 57/1/4, total bolus transit time (TBTT) 7.3 ± 1.3, 7.6 ± 1.2, and 6.9 ± 0.9 s, and complete bolus transit rate (CBTR) 66.7 ± 37.8, 61.7 ± 36.4, and 90.3 ± 14.0%, respectively. Stepwise linear regression analysis showed that age, gender, and ethnicity did not have significant effect on LESP, TBTT, esophageal peristalsis, and CBTR in patients with GERD. Conclusions. British and Chinese patients with GERD presented similar values of LESP, TBTT, and impaired esophageal peristalsis and CBTR.

Abstract
BACKGROUND Normal values of the esophageal motor function parameters for high-resolution manometry (HRM-EPT) adopted by the Chicago classification were established using the proprietary system of Given Imaging. It is conceivable that normal values of a system do not apply to data from others. Most studies using HRM were based on supine swallows, whereas deglutition occurs mostly in the upright position. We wished to establish normal values for HRM-EPT parameters obtained with the Sandhill's HRM-EPT system and compare the results in supine and sitting positions. METHODS Sixty-nine healthy volunteers, 38 females, median age 27 years, were included in this study. All underwent supine HRM, and 34 of them underwent sitting HRM, with at least 10 single 5-mL swallows for analysis obtained in each position. KEY RESULTS The normal range (5-95th percentiles) for the following parameters was calculated: distal contractile integral (DCI), 606-4998 mmHg·s·cm; contractile front velocity (CFV), 2.0-6.5 cm/s; distal latency (DL), 5.1-8.8 s; intrabolus pressure (IBP), 1.9-17.6 mmHg; upper esophageal sphincter (UES) pressure, 45.2-186.9 mmHg; esophagogastric junction (EGJ) length, 1.8-4 cm; EGJ resting pressure, 8.1-61.6 mmHg, and integrated relaxation pressure (IRP) 2.5-23.5 mmHg. Normal values of EGJ resting pressure, IRP, DCI, and IBP but not CFV, DL, and UES resting pressure were significantly lower in the sitting posture. CONCLUSIONS & INFERENCES Studies performed with Sandhill's HRM-EPT system should use its own specific normal data. Normal values should be established for different study.

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
Gastro-esophageal reflux (GER) is a common occurrence in newborns and a cause of anxiety to most parents. This physiological process needs to be closely differentiated from pathological reflux. The clinical signs in infants are generally non-specific which makes the distinction difficult. The diagnostic options in infants are limited, have low sensitivity and not readily available. Treatment of GER is challenging both for the clinician and family. The mainstay of therapy involves use of conservative modalities with limited use of pharmacological agents and surgical methods. This review aims to amalgamate evidence based guidelines to our current clinical practice.

Abstract
BACKGROUND/AIMS We used high-resolution impedance manometry (HRIM) to determine the length of breaks on the isobaric contour which would predict incomplete bolus clearance in patients in the sitting position. METHODS In total, 651 swallows in 71 patients with esophageal symptoms were studied using a solid-state HRIM system in the sitting position. Each swallow was classified as complete or incomplete bolus clearance by impedance criteria and peristaltic integrity was evaluated using 20- and 30-mmHg pressure topography isobaric contours. Correlations between the lengths of the breaks for 20- and 30-mmHg were analyzed. RESULTS Complete bolus clearance was observed in 83.3% (542/651) of swallows. Breaks of 3 and 7 cm or less were associated with a bolus clearance of 96.8% on the 20-mmHg and 94.7% on the 30-mmHg isobaric contour, respectively (P < 0.001). The areas under the ROC curves for the 20 and 30 mmHg isobaric contours were 0.900 and 0.950, respectively. The sensitivity and specificity for complete bolus clearance were 75.6% and 89.3% for breaks 3 cm or less on the 20-mmHg isobaric contour and 87.9% and 78.7% for breaks 7 cm or less on the 30-mmHg contour (P < 0.001). CONCLUSIONS Breaks of < 3 cm in the 20-mmHg isobaric contour or < 7 cm in the 30-mmHg isobaric contour were associated with com-plete bolus clearance. The threshold for breaks in the sitting position was greater than previous reports using the supine posi-tion and longer breaks predicted incomplete bolus clearance.(J Neurogastroenterol Motil 2014;20:491-496).

Abstract
Excessive belching is a commonly observed complaint in clinical practice that can occur not only as an isolated symptom but also as a concomitant symptom in patients with gastroesophageal reflux disease (GERD) or functional dyspepsia. Impedance monitoring has revealed that there are two mechanisms through which belching can occur: the gastric belch and the supragastric belch. The gastric belch is the result of a vagally mediated reflex leading to relaxation of the lower esophageal sphincter and venting of gastric air. The supragastric belch is a behavioral peculiarity. During this type of belch, pharyngeal air is sucked or injected into the esophagus, after which it is immediately expulsed before it has reached the stomach. Patients who belch excessively invariably exhibit an increased incidence of supragastric, not of gastric belches. Moreover, supragastric belches can elicit regurgitation episodes in patients with the rumination syndrome and sometimes appear to induce reflux episodes as well. Behavioral therapy has been proven to decrease belching complaints in patients with isolated excessive belching, but its effect is unknown in frequently belching patients with GERD, functional dyspepsia or rumination.

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

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is one of the most frequent benign disorders of the upper gastrointestinal tract. Management of GERD has always been controversial since modern medical therapy is very effective, but laparoscopic fundoplication is one of the few procedures that were quickly adapted to the minimal access technique. The purpose of this project was to analyze the current knowledge on GERD in regard to its pathophysiology, diagnostic assessment, medical therapy, and surgical therapy, and special circumstances such as GERD in children, Barrett's esophagus, and enteroesophageal and duodenogastroesophageal reflux. METHODS The European Association of Endoscopic Surgery (EAES) has tasked a group of experts, based on their clinical and scientific expertise in the field of GERD, to establish current guidelines in a consensus development conference. The expert panel was constituted in May 2012 and met in September 2012 and January 2013, followed by a Delphi process. Critical appraisal of the literature was accomplished. All articles were reviewed and classified according to the hierarchy of level of evidence and summarized in statements and recommendations, which were presented to the scientific community during the EAES yearly conference in a plenary session in Vienna 2013. A second Delphi process followed discussion in the plenary session. RESULTS Recommendations for pathophysiologic and epidemiologic considerations, symptom evaluation, diagnostic workup, medical therapy, and surgical therapy are presented. Diagnostic evaluation and adequate selection of patients are the most important features for success of the current management of GERD. Laparoscopic fundoplication is the most important therapeutic technique for the success of surgical therapy of GERD. CONCLUSIONS Since the background of GERD is multifactorial, the management of this disease requires a complex approach in diagnostic workup as well as for medical and surgical treatment. Laparoscopic fundoplication in well-selected patients is a successful therapeutic option.

Abstract
Achalasia is an uncommon esophageal motility disorder characterized by the selective loss of enteric neurons leading to absence of peristalsis and impaired relaxation of the lower esophageal sphincter. Per-oral endoscopic myotomy (POEM) is a novel modality for the treatment of achalasia performed by gastroenterologists and surgeons. It represents a natural orifice transluminal endoscopic surgery (NOTES) approach to Heller myotomy. POEM has the minimal invasiveness of an endoscopic procedure that can duplicate results of the surgical Heller myotomy. POEM is conceptually similar to a surgical myotomy without the inherent external incisions and post-operative care associated with surgery. Initial high success and low complications rates promise a great future for this technique. In fact, POEM has been successfully performed on patients with end-stage achalasia as an initial treatment reserving esophagectomy for those without good response. The volume of POEMs performed worldwide has grown exponentially. In fact, surgeons who have performed Heller myotomy have embraced POEM as the preferred intervention for achalasia. However, the niche of POEM remains to be defined and long term results are awaited. We describe our experience with POEM having performed the first POEM outside of Japan in 2009, the evolution of our technique, and give our perspective on its future.

Abstract
BACKGROUND Esophageal impedance monitoring has made it possible to distinguish two types of belches, designated gastric and supragastric. We aimed to compare the esophageal pressure characteristics during supragastric belches and gastric belches using combined high-resolution manometry and impedance monitoring. METHODS We included 10 patients with severe and frequent belching. Combined high-resolution manometry and impedance monitoring was performed. KEY RESULTS Whereas gastric belching was relatively rare in all patients (median incidence 2 per 90-min period), nine of the 10 patients exhibited excessive supragastric belching (36 in 90 min). Supragastric belches were characterized by: (i) movement of the diaphragm in aboral direction and increased esophagogastric junction (EGJ) pressure, (ii) decrease in esophageal pressure, (iii) upper esophageal sphincter (UES) relaxation, (iv) antegrade airflow into the esophagus, and (v) increase in esophageal and gastric pressure leading to expulsion of air out of the esophagus in retrograde direction. In contrast, gastric belches were characterized by: (i) decreased or unchanged EGJ pressure, which was significantly lower than during supragastric belches, (ii) absence of decreased esophageal pressure preceding entrance of air into the esophagus (iii) retrograde airflow into the esophagus, (iv) common cavity phenomenon, and (v) upper esophageal sphincter relaxation after the onset of the retrograde airflow. CONCLUSIONS & INFERENCES In gastric belching UES relaxation is a late event, allowing efflux of air that entered the esophagus from the stomach. In most patients with supragastric belching air is brought into the esophagus by movement of the diaphragm in aboral direction, creation of negative esophageal pressure, and UES relaxation.

Abstract
Multichannel intraluminal impedance (MII) for the evaluation of esophageal diseases was created in 1991 trying to solve previous limitations of esophageal function test. MII-pH is able to determine the physical characteristics of the refluxate (liquid, gas, or mixed) and nonacidic GER. MII-manometry can determine the presence of bolus and its relation with peristalsis. This paper makes a critical analysis of the clinical applications of MII 20 years after its creation. Literature review shows that MII made great contributions for the understanding of esophageal physiology; however, direct clinical applications are few. MII-pH was expected to identify patients with normal acid reflux and abnormal nonacidic reflux. These patients are rarely found off therapy, that is, nonacidic reflux parallels acid reflux. Furthermore, the significance of isolated nonacidic reflux is unclear. Contradictory MII-manometry and conventional manometry findings lack better understanding and clinical implication as well as the real significance of bolus transit.

How many cases of laryngopharyngeal reflux suspected by laryngoscopy are gastroesophageal reflux disease-related? World J Gastroenterol 2012; 18:4363-70. [PMID: 22969200 PMCID: PMC3436052 DOI: 10.3748/wjg.v18.i32.4363] [Citation(s) in RCA: 110] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2012] [Revised: 08/15/2012] [Accepted: 08/18/2012] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate the prevalence of gastroesophageal reflux disease (GERD) in patients with a laryngoscopic diagnosis of laryngopharyngeal reflux (LPR).
METHODS: Between May 2011 and October 2011, 41 consecutive patients with laryngopharyngeal symptoms (LPS) and laryngoscopic diagnosis of LPR were empirically treated with proton pump inhibitors (PPIs) for at least 8 wk, and the therapeutic outcome was assessed through validated questionnaires (GERD impact scale, GIS; visual analogue scale, VAS). LPR diagnosis was performed by ear, nose and throat specialists using the reflux finding score (RFS) and reflux symptom index (RSI). After a 16-d wash-out from PPIs, all patients underwent an upper endoscopy, stationary esophageal manometry, 24-h multichannel intraluminal impedance and pH (MII-pH) esophageal monitoring. A positive correlation between LPR diagnosis and GERD was supposed based on the presence of esophagitis (ERD), pathological acid exposure time (AET) in the absence of esophageal erosions (NERD), and a positive correlation between symptoms and refluxes (hypersensitive esophagus, HE).
RESULTS: The male/female ratio was 0.52 (14/27), the mean age ± SD was 51.5 ± 12.7 years, and the mean body mass index was 25.7 ± 3.4 kg/m2. All subjects reported one or more LPS. Twenty-five out of 41 patients also had typical GERD symptoms (heartburn and/or regurgitation). The most frequent laryngoscopic findings were posterior laryngeal hyperemia (38/41), linear indentation in the medial edge of the vocal fold (31/41), vocal fold nodules (6/41) and diffuse infraglottic oedema (25/41). The GIS analysis showed that 10/41 patients reported symptom relief with PPI therapy (P < 0.05); conversely, 23/41 did not report any clinical improvement. At the same time, the VAS analysis showed a significant reduction in typical GERD symptoms after PPI therapy (P < 0.001). A significant reduction in LPS symptoms. On the other hand, such result was not recorded for LPS. Esophagitis was detected in 2/41 patients, and ineffective esophageal motility was found in 3/41 patients. The MII-pH analysis showed an abnormal AET in 5/41 patients (2 ERD and 3 NERD); 11/41 patients had a normal AET and a positive association between symptoms and refluxes (HE), and 25/41 patients had a normal AET and a negative association between symptoms and refluxes (no GERD patients). It is noteworthy that HE patients had a positive association with typical GERD-related symptoms. Gas refluxes were found more frequently in patients with globus (29.7 ± 3.6) and hoarseness (21.5 ± 7.4) than in patients with heartburn or regurgitation (7.8 ± 6.2). Gas refluxes were positively associated with extra-esophageal symptoms (P < 0.05). Overall, no differences were found among the three groups of patients in terms of the frequency of laryngeal signs. The proximal reflux was abnormal in patients with ERD/NERD only. The differences observed by means of MII-pH analysis among the three subgroups of patients (ERD/NERD, HE, no GERD) were not demonstrated with the RSI and RFS. Moreover, only the number of gas refluxes was found to have a significant association with the RFS (P = 0.028 and P = 0.026, nominal and numerical correlation, respectively).
CONCLUSION: MII-pH analysis confirmed GERD diagnosis in less than 40% of patients with previous diagnosis of LPR, most likely because of the low specificity of the laryngoscopic findings.

Abstract
Gut motility and visceral sensation are two important components of normal gastrointestinal (GI) tract function. Disordered gut motility and sensation can cause significant symptoms which not only pose a health burden to patients, but may also mimic structural diseases and may generate many surgical referrals from primary care. Unfortunately, diagnostic testing for disorders of function lags well behind that for structural disease. In this article we review common presentations of functional disorders in surgical clinics, and relevant testing modalities.
