ABSTRACT

Gastroesophageal reflux disease (GERD) is a clinical condition in which gastric reflux causes symptoms or damage to the esophageal mucosa. It is managed with proton pump inhibitors, however, up to 45% of patients with suspected GERD are refractory to treatment. It is necessary to establish a true GERD diagnosis by means of a digestive endoscopy, which does not show lesions in approximately 70% of patients. In this scenario, it is necessary to perform an esophageal pH-impedance measurement, a procedure that allows to determine whether exposure to gastric acid is pathological. Of this group, patients with pathological acid exposure are diagnosed as true non-erosive reflux disease (NERD). If, in addition to not presenting esophageal lesions, they have a physiological exposure to gastric acid, they suffer from esophageal hypersensitivity or functional heartburn, which are functional disorders. These require a different approach from that of GERD or NERD, as the symptoms are not due to pathological exposure to gastric acid. The aim was to calculate the frequency of esophageal hypersensitivity and functional heartburn in patients with suspected NERD. This was a cross-sectional study. Data was collected by reviewing pH-impedance and manometry reports, 166 patients were selected. The frequency for functional disorders was 86.15%, being 46.9% for functional heartburn and 39.2% for esophageal hypersensitivity. The frequency of functional disorders was higher than that reported in previous studies. In conclusion, age, psychological conditions, dietary, cultural, ethnic or lifestyle factors inherent to our environment might play important roles in the development of functional disorders.


La enfermedad por reflujo gastroesofágico (ERGE) es una condición clínica en la que el reflujo gástrico provoca síntomas o daños en la mucosa esofágica. Se maneja con inhibidores de la bomba de protones; sin embargo, hasta el 45% de los pacientes con sospecha de ERGE son refractarios al tratamiento. Por lo cual, es necesario establecer un verdadero diagnóstico de ERGE mediante una endoscopia digestiva, que no muestra lesiones en aproximadamente el 70% de los pacientes. En este escenario, es necesario realizar una medición de pH-impedancia esofágica, procedimiento que permite determinar si la exposición al ácido gástrico es patológica. De este grupo, los pacientes con exposición patológica al ácido son diagnosticados como verdadera enfermedad por reflujo no erosiva (ERNE). Si además de no presentar lesiones esofágicas, tienen una exposición fisiológica al ácido gástrico, padecen hipersensibilidad esofágica o pirosis funcional, que son trastornos funcionales. Estos requieren un enfoque diferente al ERGE o ERNE, ya que los síntomas no se deben a una exposición patológica al ácido gástrico. El objetivo fue calcular la frecuencia de hipersensibilidad esofágica y pirosis funcional en pacientes con sospecha de ERNE. Este fue un estudio transversal. Los datos se recopilaron mediante la revisión de informes de pH-impedancia y manometría, se seleccionaron 166 pacientes. La frecuencia de trastornos funcionales fue de 86,15%, siendo 46,9% de pirosis funcional y 39,2% de hipersensibilidad esofágica. La frecuencia de trastornos funcionales fue superior a la reportada en estudios previos. En conclusión, la edad, las condiciones psicológicas, los factores dietéticos, culturales, étnicos o de estilo de vida inherentes a nuestro entorno podrían jugar un papel importante en el desarrollo de trastornos funcionales.

ABSTRACT

El reflujo gastroesofágico es una situación frecuente en el primer año de vida. En ausencia de signos y síntomas de alarma, se lo considera fisiológico. No requiere estudios y puede ser abordado por el pediatra con medidas no farmacológicas. La enfermedad por reflujo (definidaporsíntomasmolestosocomplicaciones) debe ser manejada por el gastroenterólogo. Los exámenes complementarios tienen indicaciones precisas y el tratamiento incluye medidas no farmacológicas, farmacológicas y quirúrgicas (si fuera necesario). Nuestro objetivo es describir los diferentes métodos diagnósticos, sus indicaciones y limitaciones, así como los recursos terapéuticos disponibles, incluidas las indicaciones y los efectos adversos


Gastro esophageal reflux is a frequent condition in infants. In the absence of warning symptoms and signs, it is considered physiologic. No exam is required and a non-pharmacologic approach can be instituted by pediatricians. Gastro esophageal reflux disease is characterized by troublesome symptoms or complications and should be managed by a pediatric gastroenterologist. Diagnostic tests have accurate indications and treatment includes pharmacologic and non-pharmacologic measures as well as surgery. Our objective is to describe the different diagnostic methods, their indications and limitations as well as the therapeutic resources available, including indications and adverse effects.

ABSTRACT

SUMMARY OBJECTIVE: To demonstrate the need of performing esophageal pH monitoring and manometry in patients with clinical suspicion of Gastroesophageal reflux disease, as more accurate and practical complementary exams in the indication of surgical treatment. METHODS: A systematic review was carried out in the PubMed/Medline database, based on the recommendations of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol, selecting studies in humans, published in Portuguese, Spanish, and English, from January 1, 2009 to August 5, 2020. The following descriptors were used: "reflux gastroesophageal" AND "surgery" AND "surgical treatment" AND "esophageal manometry" OR "pH monitoring". After that, retrospective or prospective observational studies with a sample of less than 100 individuals, or with limited access, reports or case series, review articles, letters, comments, or book chapters were excluded. To facilitate the application of the exclusion criteria, the Rayyan management base was used. RESULTS: Out of the 676 studies found, 19 valid and eligible studies were selected to make inferences. CONCLUSIONS: Based on the best evidence, currently, considering national particularities, performing a 24-hour esophageal pH monitoring and esophageal manometry for all patients undergoing anti-reflux surgery.

ABSTRACT

Objective:To investigate reflux symptom index (RSI), reflux finding score (RFS), esophageal motility and to correlate them with laryngopharyngeal reflux in patients with vocal cord polyps, providing guidance for clinical study.Methods:A total of 100 patients with vocal cord polyps who received treatment from January 2018 to January 2020 in Jiangshan People's Hospital were included in the observation group. A total of 100 healthy controls who concurrently received physical examination were included in the control group. RSI and RFS were used to preliminarily evaluate laryngopharyngeal reflux. The characteristics of esophageal motility and the pressure of upper and lower sphincter were monitored. The correlation between RSI, RFS, esophageal motility and laryngopharyngeal reflux was analyzed.Results:In the observation group, 35.00% of patients had RSI > 13 points, and 30.00% of patients had RFS > 7 points. The RSI and RFS in the observation group were significantly higher than those in the control group [RSI: (24.17 ± 1.14) points vs. (7.28 ± 12) points; RFS: (17.59 ± 1.52) points vs. (4.28 ± 0.21) points, t = 147.344, 86.742, both P < 0.05)]. The time to upper sphincter relaxation recovery and the duration of upper sphincter relaxation in the observation group were significantly shorter than those in the control group ( t = 5.373, 4.660, both P < 0.05). The intra pellet pressure in the observation group was significantly greater than that in the control group ( t = 2.186, P < 0.05). The length of the lower sphincter in the observation group was significantly shorter than that in the control group ( t = 4.977, P < 0.05). Correlation analysis showed that RSI was positively correlated with foreign body sensation in the throat, continuous throat clearing, nasal reflux or phlegm ( r = 0.640, 0.649, 0.507, all P < 0.05). RFS was positively correlated with disappearance of laryngeal chamber, posterior commissure hyperplasia and vocal cord edema ( r = 0.742, 0.516, 0.547, all P < 0.05). Conclusion:RSI and RFS of patients with vocal cord polyps are positively correlated with laryngopharyngeal reflux. Some patients with vocal cord polyps have dysfunction and abnormal structure of upper and lower esophageal sphincter as well as laryngopharyngeal reflux. Therefore, reflux symptom index, reflux finding score and esophageal motility can be used together to diagnose laryngopharyngeal reflux and increase the diagnosis accuracy

ABSTRACT

ABSTRACT Background: The catheter of the esophageal pH monitoring is associated with nasal and throat discomfort, and different behave in patients. The capsule of the wireless pH monitoring may cause chest pain and complications. Aim: To compare the wireless and conventional pH monitoring concerning the degree of discomfort and limitations in daily activities, complications, ability to diagnose pathological reflux, and costs. Methods: Twenty-five patients with symptoms of gastroesophageal reflux were prospectively submitted, in a simultaneous initial period, to 24-hour catheter esophageal pH monitoring and 48-hour wireless system. After removing each system, patients underwent a specific clinical questionnaire. Results: Fifteen patients (60%) pointed a higher discomfort in the introduction of the capsule (p=0.327). Discomfort and limitations in daily activities were lower on 2nd day (p<0.05); however, continued to be expressive (32% to 44%). Chest pain occurred in 13 (52%) patients. The diagnostic gain of pathological reflux was 12% with the wireless system (p=0.355). Conclusions: 1) There is no significant difference between the discomfort mentioned in the introduction of the capsule and the catheter; 2) during reflux monitoring, the wireless system provides significant less discomfort and limitations in daily activities; 3) there is no significant difference between the two methods in the ability to diagnose pathological reflux; 4) wireless pH monitoring has higher cost.


RESUMO Racional: O cateter da pHmetria esofágica associa-se ao desconforto nasal e na garganta, e comportamento diferente nos pacientes. A cápsula da pHmetria sem cateter pode causar dor torácica e complicações. Objetivo: Comparar as pHmetrias sem cateter e a convencional, em relação ao desconforto e limitações das atividades diárias, complicações, capacidade de diagnosticar refluxo patológico, e custos. Métodos: Vinte e cinco pacientes com sintomas de refluxo gastroesofágico foram prospectivamente submetidos, em um período inicial simultâneo, à pHmetria esofágica com cateter durante 24 h e à pHmetria sem cateter durante 48 h. Após a retirada de cada método, pacientes responderam o questionário clínico específico. Resultados: Quinze pacientes (60%) relataram maior desconforto na introdução da cápsula (p=0,327). Desconforto e limitações das atividades diárias foram menores no 2º dia (p< 0,05); entretanto, continuaram sendo expressivos (32% a 44%). Dor torácica ocorreu em 13 (52%) pacientes. O ganho diagnóstico no refluxo patológico foi de 12% com o sistema sem cateter (p=0,355). Conclusões: 1) Não há diferença significativa entre o desconforto relatado na introdução da cápsula e do cateter; 2) durante a monitorização do refluxo, o sistema sem cateter proporciona significativo menor desconforto e limitações das atividades diárias; 3) não há diferença significativa entre os dois métodos na capacidade de diagnosticar o refluxo patológico; 4) pHmetria sem cateter tem custo maior.

ABSTRACT

Objective@#To evaluate esophageal motility and anti-reflux barrier function in patients with different phenotypes of heartburn and negative endoscopic findings based on the Rome Ⅳ criteria.@*Methods@#From March 2011 to November 2018, 136 patients with heartburn and negative endoscopic findings were retrospectively analyzed. The patients underwent high-resolution manometry (HRM), 24-hour pH monitoring and proton pump inhibitor (PPI) test and according to the Rome Ⅳ criteria and new diagnostic procedures, they were divided into non-erosive reflux disease (NERD) group, reflux hypersensitivity (RH) group, functional heartburn (FH) group and unclassified group. During the same period, 20 healthy volunteers were selected as healthy control group. The changes of esophageal motility and HRM were analyzed among different groups. Statistical analysis was performed using one-way analysis of variance, Kruskal-Wallis H test and chi-square test.@*Results@#According to Rome Ⅳ criteria, 35 patients were enrolled into the NERD group, 43 patients were enrolled into the RH group, 48 patients were included in the FH group, and 10 patients were enrolled into unclassified group. There were no significant differences between the NERD group, the RH group, the FH group, the unclassified group and healthy control group in the length of the lower esophageal sphincter (LES), end lower esophageal sphincter resting pressure (LESP), mean LESP, 4-second-integrated relaxation pressure (4 s-IRP), distal latency (DL) , upper esophageal sphincter residual pressure (UES-RP), upper esophageal sphincter relaxation time to nadir, upper esophageal sphincter (UES) recovery time and esophagogastric junction contractile integral (EGJ-CI, all P>0.05). The distal contractile integral (DCI) of NERD group and unclassified group were both lower than that of healthy control group (919.7 mmHg·s·cm (411.7, 1 417.9) mmHg·s·cm (1 mmHg=0.133 kPa), 535.6 mmHg·s·cm (321.4, 1 513.4) mmHg·s·cm vs. 1 322.1 mmHg·s·cm (841.6, 1 918.5) mmHg·s·cm), and the differences were statistically significant (Z=-2.62 and -2.20, P=0.01 and 0.03). The upper esophageal sphincter pressure (UESP) of the unclassified group was lower than that of the healthy control group(57.0 mmHg (31.3, 77.8) mmHg vs. 70.4 mmHg (49.4, 97.8) mmHg), and the difference was statistically significant (Z=-2.64, P=0.02). There was significant difference in esophagogastric junction (EGJ) subtypes between the NERD group, the RH group, the FH group and the unclassified group (χ2=10.85, P=0.02); the proportion of type Ⅲ patients was highest in unclassified group, followed by NERD group, which were both higher than those of RH group and FH group. There was no significant difference in the proportion of esophageal motility subtypes between NERD group, RH group, FH group and unclassified group (P>0.05).@*Conclusions@#Patients with different phenotypes of heartburn and negative endoscopy finding should be classified by efficient diagnostic procedure according to the Rome Ⅳ criteria combined with HRM, 24-hour pH monitoring and PPI test. The unclassified patients need further evaluation, especially for those with effective PPI test and negative pH monitoring. However, the evaluation of anti-reflux barrier function by the HRM parameters in patients with heartburn and negative endoscopic findings has certain limitations.

ABSTRACT

Gastroesophageal reflux disease (GERD) is diagnosed according to the medical history or in response to proton pump inhibitor therapy. However, the need for further testing is always appropriate. The decisive evidence for the current diagnosis of GERD is severe erosive esophagitis of Los Angeles grade C or D, long-segment Barrett's mucosa or peptic strictures seen on endoscopy or an acid exposure time >6% on ambulatory pH or pH impedance monitoring. If ambulatory reflux monitoring correlates between reflux and the symptoms, then the diagnosis and treatment are certain. If it is difficult to clearly diagnose this malady as seen upon endoscopy and ph/pH impedance monitoring, then this review recommends the biopsy findings, motor evaluation and novel impedance metrics. Novel impedance metrics include the baseline impedance and the post reflux swallow-induced peristaltic wave index. Therefore, making a future GERD diagnosis should focus on defining the patient's phenotype. The phenotype is determined by the level of reflux exposure, clearance efficacy, anatomy of the esophageal gastric junction, and the psychological state of the patient. The purpose of this review is to clarify the diagnostic guideline for GERD according to several test methods.

ABSTRACT

ABSTRACT BACKGROUND: Prolonged monitoring increased our knowledge on gastroesophageal reflux (GER), and the disease became known as gastroesophageal reflux disease (GERD). Prolonged reflux monitoring permits the diagnosis of GERD when endoscopic findings are not enough to characterize it. OBJECTIVE: The objective of this paper is to review the current knowledge on impedance-pH monitoring, taking into account the published literature and the authors experience with 1,200 exams. METHODS: The different types of prolonged reflux monitoring, namely: conventional pHmetry, catheter-free pHmetry and impedance-pHmetry will be briefly described. The new possibilities of evaluation with impedance-pHmetry are emphasized, namely: the study of symptomatic patients in use of proton pump inhibitors (PPIs); evaluation of patients with symptoms suggestive of GERD although with normal endoscopy and normal pHmetry, diagnostic elucidation of patients with atypical symptoms or supra-esophageal symptoms, mainly chronic cough, study of patients complaining of belch, differentiating gastric and supra-gastric belching, and the proper work-up before anti-reflux surgery. RESULTS: When impedance was associated to pH monitoring, an impressive technological evolution became apparent, when compared to pH monitoring alone. The main advantages of impedance-pHmetry are: the ability to detect all types of reflux: acid, non-acid, liquid, gaseous. In addition, other important measurements can be made: the ability of the esophagus in transporting the bolus, the measurement of basal mucosal impedance and the evaluation of primary peristalsis post reflux. CONCLUSION: Impedance-pHmetry is a promising method, with great advantages over conventional pHmetry. The choice between these two types of monitoring should be very judicious. The authors suggest the importance of careful evaluation of each reflux episode by the physician responsible for the examination, necessary for the correct interpretation of the tracings.


RESUMO CONTEXTO: A monitorização prolongada ampliou o conhecimento sobre o refluxo gastroesofágico; a afecção decorrente do mesmo, passou a ser designada por doença do refluxo gastroesofágico (DRGE). O estudo prolongado do refluxo viabiliza o diagnóstico da DRGE nos casos sem alterações endoscópicas suficientes para caracterização da afecção. OBJETIVO: O objetivo do presente trabalho é apresentar uma revisão sobre a monitorização do refluxo por impedâncio-pHmetria, ponderando-se os dados de literatura com a experiência dos autores com o método em 1.200 exames realizados. MÉTODOS: São apresentados detalhes dos diferentes tipos de monitorização prolongada do refluxo; ou seja, a pHmetria convencional, a pHmetria sem cateter e a impedâncio-pHmetria. Salientam-se as novas possibilidades de avaliação que a impedâncio-pHmetria propicia e suas principais indicações: estudo de pacientes que permanecem sintomáticos durante o tratamento do refluxo com antissecretores; análise de pacientes com sintomas sugestivos de DRGE que não apresentem esofagite ao exame endoscópico e que tenham pHmetria normal; esclarecimento diagnóstico de pacientes com sintomas atípicos e supraesofágicos - em especial na tosse crônica; estudo da eructação diferenciando-as em dois grupos: gástricas e supragástricas e no auxílio na indicação do tratamento cirúrgico do refluxo. RESULTADOS: A monitorização associando duas modalidades de avaliação: a impedancio-pHmetria representa evolução tecnológica expressiva em relação à modalidade baseada apenas na análise do pH (pHmetria). As principais vantagens da impedâncio-pHmetria são: possibilidade de avaliação de todas modalidades de refluxo; ou seja, ácido, não-ácido, líquido e gasoso e também a possibilidade de estudo de outras variáveis importantes; ou seja: capacidade de transporte do bolus, impedância basal do esôfago e peristalse pós refluxo. CONCLUSÃO: A impedancio-pHmetria é um método promissor, com grandes vantagens sobre a pHmetria convencional. A escolha do tipo de monitorização a ser utilizada, deve ser criteriosa. Os autores destacam a importância da análise cuidadosa de cada episódio de refluxo, pelo médico responsável pela execução do exame, para correta interpretação e valorização dos dados obtidos.

ABSTRACT

ABSTRACT BACKGROUND: Dysphagia is described as a complaint in 32% of patients with laryngitis. OBJECTIVE: The objective of this investigation was to evaluate oral and pharyngeal transit of patients with laryngitis, with the hypothesis that alteration in oral-pharyngeal bolus transit may be involved with dysphagia. METHODS: Videofluoroscopic evaluation of the swallowing of liquid, paste and solid boluses was performed in 21 patients with laryngitis, 10 of them with dysphagia, and 21 normal volunteers of the same age and sex. Two swallows of 5 mL liquid bolus, two swallows of 5 mL paste bolus and two swallows of a solid bolus were evaluated in a random sequence. The liquid bolus was 100% liquid barium sulfate and the paste bolus was prepared with 50 mL of liquid barium and 4 g of food thickener (starch and maltodextrin). The solid bolus was a soft 2.2 g cookie coated with liquid barium. Durations of oral preparation, oral transit, pharyngeal transit, pharyngeal clearance, upper esophageal sphincter opening, hyoid movement and oral-pharyngeal transit were measured. All patients performed 24-hour distal esophageal pH evaluation previous to videofluoroscopy. RESULTS: The evaluation of 24-hour distal esophageal pH showed abnormal gastroesophageal acid reflux in 10 patients. Patients showed longer oral preparation for paste bolus and a faster oral transit time for solid bolus than normal volunteers. Patients with laryngitis and dysphagia had longer preparation for paste and solid boluses, and a faster oral transit time with liquid, paste and solid boluses. CONCLUSION: A longer oral preparation for paste and solid boluses and a faster transit through the mouth are associated with dysphagia in patients with laryngitis.


RESUMO CONTEXTO: Disfagia é uma queixa presente em 32% dos pacientes com laringite. OBJETIVO: O objetivo desta investigação foi avaliar o trânsito oral e faríngeo de pacientes com laringite, com a hipótese de que a alteração no trânsito do bolo pela boca e faringe pode estar envolvida com a queixa de disfagia. MÉTODOS: A avaliação videofluoroscópica da deglutição de bolos líquido, pastoso e sólido foi realizada em 21 pacientes com laringite, 10 deles com disfagia e 21 voluntários normais da mesma idade e sexo. Duas deglutições de 5 mL de bolo líquido, duas deglutições de bolo pastoso e duas deglutições de bolo sólido foram avaliadas em sequência casual definida por sorteio. Bolo líquido foi sulfato de bário 100%, e o bolo pastoso foi preparado com 50 mL de bário líquido e 4 g de espessante alimentar (amido e maltodextrina). O bolo sólido foi 2,2 g de uma bolacha macia embebida em bário líquido. A duração da preparação oral, trânsito oral, trânsito faríngeo, depuração da faringe, abertura do esfíncter superior do esôfago, movimento do hióide e do trânsito oral-faríngeo foram medidas. Precedendo a videofluoroscopia todos pacientes realizaram exame de pHmetria de 24 horas. RESULTADOS: O registro do pH intraesofágico distal revelou resultado anormal em 10 pacientes. Pacientes com laringite apresentaram maior duração da preparação oral para bolo pastoso e um tempo de trânsito oral mais rápido para bolo sólido. Os pacientes com laringite e disfagia tiveram uma preparação oral mais longa para bolo pastoso e sólido e tempo de trânsito oral menor com bolos líquido, pastoso e sólido. CONCLUSÃO: Preparação oral mais longa para bolos pastoso e sólido e trânsito mais rápido através da boca são situações associadas com a presença de disfagia em pacientes com laringite.

ABSTRACT

Objective@#The consistency and characteristics of 24-hour multichannel intraluminal impedance(MII)-pH monitoring and Dx-pH monitoring in the diagnosis of laryngopharyngeal reflux were investigated.@*Methods@#Fifty-two patients with laryngopharyngeal reflux related symptoms or disease between March and October 2017 were included in this study.All patients were evaluated with 24-hour MII-pH monitoring and Dx-pH monitoring at the same time, recording each patient′s number of positive laryngopharyngeal reflux events, time of acid clearance and Ryan index.The data was analysed with Mann-Whitney U test and consistency check.@*Results@#Among all 52 patients, 16 patients(30.7%) had a positive MII-pH monitoring result and 14 patients(26.9%) had a positive Dx-pH monitoring results.The consistency of both technique for measurement of laryngopharyngeal reflux was general(κ=0.626). With MII-pH monitoring for reference, the sensitivity and specificity of 24-hour pH monitoring were 68.8% and 91.7%.A total of 62 positive reflux events(pH<4) were measured with MII-pH monitoring, and 50 positive reflux events(upright pH<5.5 or supine pH<5.0)were detected by Dx-pH monitoring.There were 44 positive reflux events detected by both techniques, the mean time of acid clearance was 22.8[13.5; 42.6] s. Correspondingly, 18 reflux events were measured by MII-pH monitoring without positive results of Dx-pH monitoring, the mean time of acid clearance was 5.2[3.5; 6.5] s. There was significant difference in the time of acid clearance between two groups(U=858.5, P<0.05).@*Conclusions@#Dx-pH monitoring can accurately measure the change of pH value in airway, but exists the possibility of misdiagnosis especially when the time of acid clearance in laryngopharynx is short. MII-pH and Dx-pH monitoring can be complementary technique in the diagnosis of laryngopharyngeal reflux.

ABSTRACT

Background:Postprandial proximal gastric acid pocket (PPGAP)is an unbuffered layer of high acidity in the proximal stomach postprandially. It is considered to play an important role in gastroesophageal reflux disease (GERD). Aims:To investigate the effect of PPGAP in GERD. Methods:Sixty outpatients with GERD,including 20 non-erosive reflux disease (NERD),20 mild reflux esophagitis (RE)and 20 moderate-to-severe RE from Mar. 2014 to Dec. 2016 at the Second Affiliated Hospital of Xi'an Jiaotong University were enrolled. Twenty healthy volunteers were served as controls. All the subjects underwent a high-resolution esophageal manometry in fasting state to identify the location of the lower border of the lower esophageal sphincter (LBLES). Then a station pull-through pH monitoring was performed from 5 cm below the LBLES (stomach)to the esophagus in increments of 1 cm in fasting state and repeated after a standardized meal to detect the PPGAP. Results:PPGAP was identified in all the subjects. There were no significant differences in appearing time of PPGAP among healthy volunteers and different subtypes of GERD (P >0.05 ). Compared with the healthy volunteers,the disappearing time of PPGAP was significantly later and the lasting time was significantly longer in patients with NERD,mild RE and moderate-to-severe RE (P<0.05);meanwhile,the length of PPGAP was enlarged and the nadir pH and mean pH were decreased in NERD,mild RE and moderate-to-severe RE (P<0.05). When comparison was made between different subtypes of GERD,no significant differences were observed in above-mentioned parameters (P>0.05). Conclusions:PPGAP is present generally in normal individuals and GERD patients,and is lasting longer, more acidic and enlarged in length in GERD patients than in normal individuals. PPGAP may be the reservoir from which acid reflux events originate and contributes to the development of GERD.

ABSTRACT

INTRODUCCIÓN: Los inhibidores de la bomba de protones son la terapia médica más efectiva para la enfermedad de reflujo gastroesofágico, pero su inicio de acción puede ser lento. OBJETIVO: Evaluar la literatura referida a la eficacia del omeprazol y bicarbonato de sodio en la enfermedad por reflujo gastroesofágico. MÉTODOS: Revisión sistemática de la literatura desde el año 2000. Se revisaron los manuscritos relativos a la efectividad del tratamiento de la enfermedad por reflujo gastroesofágico. Se extrajo la información relevante, la cual fue subsecuentemente analizada con estadística descriptiva. RESULTADOS: Se incluyó información de cuatro estudios. Dos estudios compararon la eficacia de omeprazol y bicarbonato de sodio versus omeprazol, y un estudio comparó la eficacia de la dosis diaria matutina con la nocturna. El otro estudio comparó omeprazol más bicarbonato de sodio y alginato versus omeprazol. No hubo diferencia entre omeprazol con bicarbonato de sodio y omeprazol. Sin embargo, hubo una tendencia hacia una respuesta más sostenida y una mayor proporción de alivio total sostenido por 30 minutos con omeprazol y bicarbonato de sodio. CONCLUSIÓN: La terapia con omeprazol y bicarbonato de sodio no es más efectiva que el omeprazol en el tratamiento de la enfermedad por reflujo gastroesofágico. Sin embargo, la información sugiere que puede tener una respuesta más sostenida y un alivio total de mayor duración.


BACKGROUND: Proton pump inhibitors are the most effective medical therapy for gastroesophageal reflux disease, but their onset of action may be slow. OBJECTIVES: To assess the available literature regarding the efficacy of omeprazole/sodium bicarbonate in gastroesophageal reflux patients. METHODS: A systematic review was conducted. A systematic literature search starting from 2000. Reviewed manuscripts concerning the effectiveness of omeprazole/sodium bicarbonate treatment in gastroesophageal reflux disease were reviewed and the data were extracted. Data were subsequently analyzed with descriptive statistics. RESULTS: This review included information of four studies. Two trials compared the efficacy of omeprazole/sodium bicarbonate versus omeprazole. One study compared the efficacy of once-daily morning or nighttime dosing. And another study compared omeprazole/sodium bicarbonate/alginate versus omeprazole. In total, there was no difference between omeprazole/sodium bicarbonate and omeprazole. However, there is a trend towards more sustained response and a greater proportion of patients with sustained total relief by 30 minutes with omeprazole/sodium bicarbonate. CONCLUSION: Omeprazole/sodium bicarbonate therapy is not more effective than omeprazole in the treatment of gastroesophageal reflux disease. However, data obtained suggest that it can have a more sustained response and sustained total relief.

ABSTRACT

The prevalence of gastroesophageal reflux disease (GERD) and the incidence of some of its complications have risen strikingly over the last few decades. With the accumulation in our understanding on the pathophysiology of GERD along with the development of proton pump inhibitors, the diagnostic and therapeutic approaches to the GERD have changed dramatically over the past decade. However, The GERD still poses a problem to many clinicians since the spectrum of the disease has evolved to encompass more challenging presentations such as refractory GERD and extraesophageal manifestations. The aim of this article was to provide a review of available current diagnostic tests of the GERD, includes proton pump inhibitor test, ambulatory pH monitoring, impedance pH monitoring, mucosa impedance, and high resolution manometry. This review discusses different modalities for the work up of GERD.

ABSTRACT

BACKGROUND/AIMS: Neurologically impaired patients frequently suffer from gastrointestinal tract problems, such as gastroesophageal reflux disease (GERD). In this study, we aimed to define the risk factors for GERD in neurologically impaired children. METHODS: From May 2006 to March 2014, 101 neurologically impaired children who received 24-hour esophageal pH monitoring at Severance Children’s Hospital were enrolled in the study. The esophageal pH finding and the clinical characteristics of the patients were analyzed. RESULTS: The reflux index was higher in patients with abnormal electroencephalography (EEG) results than in those with normal EEG results (p=0.027). Mitochondrial disease was associated with a higher reflux index than were epileptic disorders or cerebral palsy (p=0.009). Patient gender, feeding method, scoliosis, tracheostomy, and baclofen use did not lead to statistical differences in reflux index. Age of onset of neurological impairment was inversely correlated with DeMeester score and reflux index. Age at the time of examination, the duration of the disease, and the number of antiepileptic drugs were not correlated with GER severity. CONCLUSIONS: Early-onset neurological impairment, abnormal EEG results, and mitochondrial disease are risk factors for severe GERD.

ABSTRACT

The symptoms of gastroesophageal reflux may be induced by acid reflux, nonacidic or weakly acidic reflux, and also can occur with hypersensitive esophagus, esophageal motility disorders, or other organic/anatomical abnormalities of esophagus.Refractory gastroesophageal reflux disease (GERD) denotes the symptoms of GERD could not be remitted with the standard dosage proton pump inhibitor (PPI) therapy.In most patients with refractory symptoms the etiology is of non-reflux-related causes, such as eosinophilic esophagitis, esophageal motility disorders, gastroparesis, or concomitant functional gastrointestinal disorders.A careful and detailed understanding of patient's medical history, examination with endoscopy and biopsy pathology, and esophageal pH-impedance monitoring are very important for identifying the potential cause.

ABSTRACT

Objective@#To explore the utility of pharyngeal pH monitoring which positive standard is Ryan index in diagnosis of laryngopharyngeal reflux disease.@*Methods@#In a retrospective study, clinical data of 590 patients who had symptoms laryngopharyngeal reflux disease from February 2016 to March 2017 were analyzed. All patients were received electronic laryngoscopy, assessment of reflux symptom index(RSI) and reflux finding score(RFS), and pharyngeal pH monitoring. SPSS 19.0 software was used to analyze the date.@*Results@#There were 94 patients whose Ryan index were positive(15.93%). Among the 94 patients, 70 were positive during upright, 12 during supine and 12 during both upright and supine. There were 40 patients(6.78%)with pH decline events related to symptoms, while those Ryan index were normal. There were 536(90.85%), 417(70.68%), 233(39.49%) and 117(19.83%) patients with pH<6.5, pH<6.0, pH<5.5 and pH<5.0 events respectively. The positive rate of RSI, RFS, RSI and RFS, RSI or RFS were 44.24%, 16.78%, 7.12%, 53.90% respectively. The RFS score in Ryan index positive group was higher than that in Ryan index negative group[(8.2±2.4) vs (4.0±2.9), u=5.424, P<0.05], while the RSI score in Ryan index positive group was not statistically different from that in Ryan index negative group[(11.3±6.2) vs (12.7±5.8), t=1.247, P=0.167].@*Conclusions@#Pharyngeal pH monitoring is an objective and non-invasive method which can reflect laryngopharyngeal reflux directly. However, with the Ryan index as a criterion for the diagnosis of laryngopharyngeal reflux disease, partial patients may be missed. Further studies are needed to obtain more accurate and objective laryngopharyngeal pH statistical index for diagnosis of laryngopharyngeal reflux disease.

ABSTRACT

Objective To compare the diagnostic value of using 24-hour combined esophageal multichannel intraluminal impedance and pH monitoring (MII-pH) in the diagnosis of gastro-esophageal reflux (GER) and pH monitoring alone in critically ill patients. Methods A prospective observational study was performed including 116 critically ill adult patients admitted to ICU of Peking Haidian Hospital from Jul. 2013 to Dec. 2014. All the patients underwent 24-hour combined M II-pH monitoring. GER episodes were recorded and its pH was recorded (acidic, weakly acidic and weakly alkaline) and its composition was recorded (liquid, mixed and gas reflux). The results of the M II -pH and the pH were monitored and compared. The demographic characteristics and clinical information were recorded. Results M II-pH was monitored for 5024 episodes of GER in 115 of 116(99.1%) patients, with a mean of 43.28±3.96 episodes per patient (median, 34 episodes; range, 0-196 episodes). The pH monitoring detected 1868 episodes (100% acid) in only 54 of 116(46.6%) patients, with a mean of 7.66±1.65 episodes per patient (median, 0 episodes; range, 0-81 episodes). The number of episode of all reflux and liquid reflux diagnosed by pH monitoring alone was less than those diagnosed by M II-pH monitoring (P=0.000), and there was no correlation in the episodes number of all reflux and liquid reflux between the two techniques (r=0.119, 0.231). Only a moderate correlation was found in the number of episodes of acidic reflux between the two techniques (r=0.656). Conclusion M II-pH monitoring is more sensitive than pH monitoring alone for establishing the diagnosis of GER.

ABSTRACT

BACKGROUND/AIMS: To evaluate the characteristic properties of laryngopharyngeal reflux (LPR) and gastroesophageal reflux (GER) in children with otitis media with effusion (OME) using 24-hour multichannel intraluminal impedance combined with dual-probe (pharyngeal and esophageal) pH-metry. METHODS: Children aged 7-10 years of age with OME underwent 24-hour multichannel intraluminal impedance pH-metry. The upper pH sensor was situated 1 cm above the upper esophageal sphincter, and the lower pH sensor was placed 3-5 cm above the lower esophageal sphincter. Parents were asked to complete the gastroesophageal reflux assessment of symptoms in a pediatrics questionnaire. RESULTS: Twenty-eight children were enrolled; LPR was detected in 19 (67.9%) children. The criteria of the LPR diagnosis was the presence of at least one supraesophageal episode with a pH 0.2. In total, 64 episodes were observed. Assessment of all LPR episodes showed the presence of 246 episodes in the entire study. A considerable predominance of weakly acidic episodes (87.8%) was noted; there were 6.5% acidic episodes, and weakly alkaline episodes reached 5.7%. Pathological GER was noted in 10 (35.7%) subjects. Acid GER was detected in 8 children, 2 of whom demonstrated non-acidic reflux. In the LPR-negative patients, no pathological GER was confirmed with the exception of a single case of non-acidic reflux. CONCLUSIONS: LPR was frequently noted in the group of children with OME, and it might be an important risk factor in this common disease.

ABSTRACT

Gastroesophageal reflux disease (GERD) is a disease predominantly seen in the West but there is a rising trend in Asia. Ambulatory 24-hour catheter-based pH monitoring has been the de facto gold standard test for GERD that correlates symptoms with acid reflux episodes. However, drawbacks such as patients' discomfort, and catheter displacement render the test as cumbersome and error-prone. The Bravo pH wireless system is designed to be user-friendly and has an added advantage of prolonged pH monitoring. The system is comparable to the catheter-based pH monitoring system in terms of diagnostic yield and symptom-reflux association. Indications include evaluation of patients with refractory GERD symptoms and prior to anti-reflux surgery. Bravo utilizes a wireless pH-sensing capsule with a complete prepackaged system, and a data processing software. The capsule may be positioned indirectly using endoscopic or manometric landmarks or under direct endoscopic guidance. Optimal threshold cut-off values are yet to be standardized but based on available studies, for the Asian population, it may be recommended for total % time pH < 4 of 5.8 over 48 hours. Cost is a limitation but capsule placement is relatively safe although technical failures may be seen in small percentage of cases.
