ABSTRACT An adequate approach to refractory gastroesophageal reflux disease (rGERD) is essential for achieving therapeutic success. From the precise definition of rGERD to the detailed characterization of its phenotypes, it will pave the way for the customization of optimal therapy for each patient. In this narrative literature review, the aim is to provide an updated synthesis of the utility of various diagnostic tools and explore the wide range of therapeutic options, both medical and invasive, available for this condition.
ABSTRACT
Introduction: Two parameters of high-resolution esophageal manometry are used to observe the function of the esophagogastric junction (EGJ): the anatomical morphology of the EGJ and contractile vigor, which is evaluated with the esophagogastric junction contractile integral (EGJ-CI). To date, how these parameters behave in different gastroesophageal reflux disease (GERD) phenotypes has not been evaluated. Materials and methods: An analytical observational study evaluated patients with GERD confirmed by pH-impedance testing and endoscopy undergoing high-resolution esophageal manometry. The anatomical morphology of the EGJ and EGJ-CI was assessed and compared between reflux phenotypes: acid, non-acid, erosive, and non-erosive. Results: 72 patients were included (63% women, mean age: 54.9 years), 81.9% with acid reflux and 25% with erosive esophagitis. In the latter, a decrease in EGJ-CI (median: 15.1 vs. 23, p = 0.04) and a more significant proportion of patients with type IIIa and IIIb EGJ (83.3% vs 37.1%, p < 0.01) were found. No significant differences existed in the manometric parameters of patients with and without acid and non-acid reflux. Conclusion: In our population, EGJ-CI significantly decreased in patients with erosive GERD, suggesting that it could be used to predict this condition in patients with GERD. This finding is also related to a higher proportion of type III EGJ and lower pressure at end-inspiration of the lower esophageal sphincter in this reflux type.
Introducción: Para observar la función de la unión esofagogástrica (UEG) se utilizan dos parámetros de la manometría esofágica de alta resolución: la morfología anatómica de la UEG y el vigor contráctil, el cual se evalúa con la integral de contractilidad distal de la unión esofagogástrica (IC-UEG). Hasta el momento, no se ha evaluado cómo se comportan estos parámetros en los diferentes fenotipos de enfermedad por reflujo gastroesofágico (ERGE). Metodología: Estudio observacional analítico en el que se evaluaron pacientes con ERGE confirmado por pH-impedanciometría y endoscopia, llevados a manometría esofágica de alta resolución. Se evaluó la morfología anatómica de la UEG y la IC-UEG, y se comparó entre los diferentes fenotipos de reflujo: ácido, no ácido, erosivo y no erosivo. Resultados: Se incluyó a 72 pacientes (63% mujeres, edad media: 54,9 años), 81,9% con reflujo ácido y 25% con esofagitis erosiva. En este último grupo se encontró una disminución de la IC-UEG (mediana: 15,1 frente a 23, p = 0,04) y una mayor proporción de pacientes con UEG tipo IIIa y IIIb (83,3% frente a 37,1%, p < 0,01). No se encontraron diferencias significativas en los parámetros manométricos de los pacientes con y sin reflujo ácido y no ácido. Conclusión: En nuestra población, la IC-UEG estuvo significativamente disminuida en los pacientes con ERGE erosivo, lo que sugiere que podría ser utilizada como un predictor de esta condición en pacientes con ERGE. Este hallazgo también se relaciona con mayor proporción de UGE tipo III y menor presión al final de la inspiración del esfínter esofágico inferior en este tipo de reflujo.
ABSTRACT
Abstract Objective: To establish if the Reflux Symptom Index (RFI) and the Reflux Finding Score (RFC) can help establish the differential diagnosis in patients with distinct causes of chronic laryngopharyngitis. Methods: A group of 102 adult patients with chronic laryngopharyngitis (Group A - 37 patients with allergic rhinitis; Group B - 22 patients with Obstructive Sleep Apnea (OSA); Group C -43 patients with Laryngopharyngeal Reflux (LPR)) were prospectively studied. Chronic laryngitis was diagnosed based on suggestive symptoms and videolaryngoscopic signs (RSI ≥ 13 and RFS ≥7). Allergies were confirmed by a positive serum RAST, OSA was diagnosed with a positive polysomnography, and LPR with a positive impedance-PH study. Discriminant function analysis was used to determine if the combination of RSI and RFS scores could differentiate between groups. Results: Patients with respiratory allergies and those with LPR showed similar and significantly higher RSI scores when compared to that of patients with OSA (p < 0.001); Patients with OSA and those with LPR showed similar and significantly higher RFS scores when compared to that of patients with Respiratory Allergies (OSA vs. Allergies p < 0.001; LPR vs. Allergies p < 0.002). The combination of both scores held a higher probability of diagnosing OSA (72.73%) and Allergies (64.86%) than diagnosing LPR (51.16%). Conclusions: RSI and RFS are not specific for reflux laryngitis and are more likely to induce a false diagnosis if not used with diligence.
ABSTRACT
OBJECTIVE@#To identify specific Chinese medicines (CMs) that may benefit patients with gastroesophageal reflux disease (GERD), and explore the action mechanism.@*METHODS@#Domestic and foreign literature on the treatment of GERD with CMs was searched and selected from China National Knowledge Infrastructure, China Science and Technology Journal Database, Wanfang Database, and PubMed from October 1, 2011 to October 1, 2021. Data from all eligible articles were extracted to establish the database of CMs for GERD. Apriori algorithm of data mining techniques was used to analyze the rules of herbs selection and core Chinese medicine formulas were identified. A system pharmacology approach was used to explore the action mechanism of these medicines.@*RESULTS@#A total of 278 prescriptions for GERD were analyzed, including 192 CMs. Results of Apriori algorithm indicated that Evodiae Fructus and Coptidis Rhizoma were the highest confidence combination. A total of 32 active ingredients and 66 targets were screened for the treatment of GERD. Enrichment analysis showed that the mechanisms of action mainly involved pathways in cancer, fluid shear stress and atherosclerosis, advanced glycation end product (AGE), the receptor for AGE signaling pathway in diabetic complications, bladder cancer, and rheumatoid arthritis.@*CONCLUSION@#Evodiae Fructus and Coptidis Rhizoma are the core drugs in the treatment of GERD and the potential mechanism of action of these medicines includes potential target and pathways.

ObjectiveTo evaluate the clinical efficacy and adverse effects of Shugan Hewei prescription combined with vonoprazan in the treatment of refractory gastroesophageal reflux disease （RGERD） due to qi depression and phlegm obstruction. MethodEighty RGERD patients who met the inclusion criteria underwent 24-hour pH impedance and high-resolution esophageal manometry and electronic gastroscopy. The 80 patients were randomly assigned to an observation group （Shugan Hewei prescription， one bag each time， twice a day + vonoprazan， 20 mg each time， once a day） and a control group （vonoprazan， 20 mg each time， once a day） by the random number table method. The treatment in both groups lasted for 4 weeks. The clinical efficacy was examined. The scores of TCM symptoms （pharyngeal discomforts such as phlegm obstruction， retrosternal discomfort， and belching）， somatic symptoms， quality of life， and improvement of esophageal mucosa under gastroscopy were observed in both groups before treatment and after treatment for 2 and 4 weeks. ResultSeventy-five patients completed the trial were included in this study， including 38 patients in the observation group and 37 patients in the control group. The total response rate in the observation group was 89.47%（34/38）， which was higher than that （62.16%，23/37） in the control group （χ2=13.014， P<0.01）. After treatment， the scores of esophageal mucous membrane， reflux disease symptoms， TCM symptoms， gastroesophageal reflux disease health-related quality of life scale （GERD-HRQL）， and somatic self-rating scale （SSS） decreased in both groups（P<0.05）. Moreover， the observation group outperformed the control group in alleviating heartburn， acid reflux， throat discomforts， midnight coughing， nausea and dry vomiting， mucousy mouth， and insomnia in the patients with GERD （P<0.05，P<0.01）. However， the two groups showed no statistically significant differences in the improvement of esophageal mucosa after treatment. ConclusionThe combination of Shugan Hewei prescription with vonoprazan was superior to vonoprazan alone in treating RGERD regarding clinical symptoms， physical signs， quality of life， and somatic symptoms， without causing obvious adverse effects.
ABSTRACT
Objective:To explore the effect of abdominal breathing exercises at different periods on the gastrointestinal symptoms, quality of life and proton pump inhibitor dependency in patients with gastroesophageal reflux disease (GERD). To provide reference for patients to choose the best time for abdominal breathing exercises.Methods:This was a prospective study. From March 2020 to December 2021, totally 108 GERD patients were collected in digestive outpatient clinic of Yibin Hospital of Chinese Medicine Hospital by convenient sampling method, they were randomly divided into pre meal group, 1 h postprandial group and 2 h postprandial group with 36 cases in each group. All patients in the three groups were given abdominal breathing training for 8 weeks on the basis of conventional acid suppression drug treatment and nursing. The training time of pre meal group, 1 h postprandial group and 2 h postprandial group was at 30 min before meal, 1 h after meal, 2 h after meal, respectively. Before and after 8 weeks of intervention, the difference of gastrointestinal symptoms and quality of life were assessed by Reflux Disease Ouestionnaire (RDQ) and the MOS 36 Item Short Form Health Survey (SF-36). Patients followed up for 12 weeks after drug withdrawal, the medication of proton pump inhibitor (PPI) between three groups were compared.Results:There was no significant difference in RDQ score and SF-36 score among the three groups before intervention ( P>0.05). After intervention, the symptom scores were (7.89 ± 1.86) in the 1 h postprandial group, lower than in the pre meal group (10.38 ± 1.81) and in the 2 h postprandial group (9.64 ± 1.65), the difference was statistically significant ( t = 5.83, 4.06, both P<0.01). The scores of each demensions in SF-36 were higher in the 1 h postprandial group compared to the pre meal group and the 2 h postprandial group, the differences were statistically significant ( t values were 2.04-3.70, all P<0.05). After followed up for 12 weeks, the PPI discontinuation rate was 71.43% in the 1 h postprandial group, higher than in the pre meal group 44.12% and in the 2 h postprandial group 45.45%, the differences were statistically significant ( χ2 = 5.28, 4.73, both P<0.05). Conclusions:Abdominal breathing exercises at 1 hour after meal can effectively alleviate gastrointestinal symptoms, promote quality of life and decrease the proton pump inhibitor dependency of GERD patients.
ABSTRACT
Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy characterized by simple operation and few postoperative complications have gradually become the two most commonly used surgical methods in clinical practice.A series of complications often occur after bariatric surgery,including gallstone disease,anemia,malnutrition,gastroesophageal reflux disease,kidney stones,and birth defects in offspring of women of childbearing age.There are controversies regarding the causes and countermeasures of these complications.This article mainly reviews the risk factors and countermeasures for the complications after bariatric surgery.

Gastroesophageal reflux disease （GERD） is a frequently and commonly occurring disease in clinic. In recent decades， with the development in pathophysiology and drug researches， modern medicine has achieved remarkable progress and results in diagnosis and treatment. However， the treatments for non-erosive reflux disease， refractory gastroesophageal reflux disease， proton pump inhibitor resistance， overlap of disease symptoms， and extraesophageal symptoms are limited and ineffective. Traditional Chinese medicine （TCM） was widely used in clinical practice， which has been proved effective in relieving symptoms and improving the quality of life. Sponsored by China Association of Chinese Medicine （CACM） and undertaken by the Spleen and Stomach Disease Branch of CACM， "the 12th Youth Salon of Clinical Predominance Disease Series （GERD）" invited 18 authoritative digestive experts of TCM and western medicine to discuss "the difficulties of clinical diagnosis and treatment of GERD and TCM advantages". The focus issues such as modern medical diagnosis and treatment achievements and contributions， improvement and maintenance of symptoms， response to overlapping disease symptoms， reduction and withdrawal of acid suppressors， and treatment of extra-esophageal symptoms were discussed in depth. TCM and western medicine exchanged and complemented each other's strengths， combing the difficulties of modern medical diagnosis and treatment， which clarified the positioning and advantages of TCM and provided guidance for clinical and scientific research.
ABSTRACT
Dental erosion is characterized by progressively destroyed teeth, which has no relation to bacteria but to chemicals. Some internal factors, such as gastroesophageal reflux induced by bulimia, anorexia, gastrointestinal diseases, or drugs, and external factors, such as diet, drugs, and occupational acid exposure, are considered promotive factors for this disease. This article presents a patient suffering from severe dental erosion in the whole dentition, especially in the maxillary teeth, due to gastroesophageal reflux induced by glucocorticoid therapy for optic neuritis. This article discusses the mechanism between optic neuritis glucocorticoid therapy and dental erosion.

ABSTRACT
Resumen Introducción: Una encuesta nacional en población abierta mostró que la enfermedad por reflujo gastroesofágico (ERGE) tiene alta prevalencia en México. Objetivo: Comparar la eficacia y seguridad de dos isómeros, dexrabeprazol (10 mg) versus esomeprazol (20 mg), en el tratamiento de la ERGE durante cuatro semanas. Métodos: Ensayo clínico fase III, aleatorizado, multicéntrico, prospectivo, doble ciego, en dos grupos que incluyeron 230 pacientes. Resultados: Con ambos tratamientos se observó disminución estadísticamente significativa en la severidad de los síntomas de ERGE (pirosis, regurgitación, dolor epigástrico y disfagia), evaluados mediante una escala visual análoga. La puntuación promedio de dexrabeprazol en el Cuestionario de Carlsson-Dent a los 28 días fue de 2.12 y la de esomeprazol de 3.02. Ambos tratamientos fueron efectivos, sin diferencia estadísticamente significativa (p < 0.05). En el Cuestionario de Salud SF-36 se observó que ambos mejoraron la puntuación en la calidad de vida, sin diferencia significativa. Ambos medicamentos fueron bien tolerados y el perfil de incidencia de eventos adversos fue bajo. Conclusiones: En el tratamiento de ERGE no erosiva, el uso de 10 mg/día de dexrabeprazol es tan efectivo como 20 mg/día de esomeprazol, con la ventaja de que la dosis es menor con un adecuado perfil de seguridad.
Abstract Introduction: A national survey in the general population showed that gastroesophageal reflux disease (GERD) is highly prevalent in Mexico. Objective: To compare the efficacy and safety of two isomers, dexrabeprazole (10 mg) vs. esomeprazole (20 mg), in the treatment of GERD for four weeks. Methods: Randomized, multicenter, prospective, double-blind phase III clinical trial in two groups that included 230 patients. Results: A statistically significant decrease in the severity of GERD symptoms (heartburn, regurgitation, epigastric pain and dysphagia), evaluated using a visual analogue scale, was observed with both treatments. Mean score for dexrabeprazole on Carlsson-Dent questionnaire at 28 days was 2.12, and for esomeprazole, 3.02. Both treatments were effective, with no statistically significant difference being recorded (p < 0.05). On SF-36 health questionnaire, both were observed to improve the quality-of-life score, with no significant difference being identified. Both drugs were well tolerated, and the adverse event incidence profile was low. Conclusions: In the treatment of non-erosive GERD, the use of dexrabeprazole at 10 mg/day is as effective as esomeprazole 20 mg/day, with the advantage that the dose is lower with an appropriate safety profile.
ABSTRACT
Aim: The aim of this study was to evaluate the role of histopathological and histomorphometric features in oesophageal biopsy of patients presenting with symptoms of Gastroesophageal Reflux Disease (GERD). Material and Methods: Present study included 42 patients and 12 controls. Complete clinical evaluation followed by endoscopic examination of the patients was done and multipleoesophageal biopsies were taken. Biopsies were processed routinely and stained with Hematoxylin and Eosin and examined for any changes related to GERD. Morphometric assessment was done by using Leitz optical micrometer. The histological scoring was done based on the parameters: basal cell hyperplasia, stromal papillae elongation, cells with irregular nuclear contour (CINC), eosinophilic infiltrate, gastric and intestinal metaplasia. A numerical score was assigned to each parameter and sum of these scores represented the total score. Statistics: The statistical analysis was done using graph pad prism, Medcalc software and Windows MS office. P value and mean standard deviation (SD) was calculated. Results: The endoscopic findings of all the controls and 83.33% of patients were normal. Only 16.67% of patients had reflux associated changes of varying grades on endoscopy. Oesophageal biopsy of all patients had changes related to GERD on histology. Immunohistochemistry confirmed that cells with irregular nuclear contour were T- lymphocytes. The mean (SD) histological scoring of control and patients were 1.75 (0.62) and 5.66 (1.31) respectively. The difference was considered to be statistically significant (P < 0.001). Thus, it was suggested that a cut-off of histological score > 3 can be used to indicate GERD. Conclusion: Patients with gastroesophageal reflux symptoms can have normal endoscopic findings but can be diagnosed on the basis of histological changes in the squamous epithelium. Scoring of the histopathological parameters along with the cut-off value can give a definitive diagnosis of GERD.
ABSTRACT
Background: Gastroesophageal reflux disease (GERD) is a common condition that affects about 20- 30% of the adult population, presenting with a broad spectrum of symptoms and varying degrees of severity and frequency. Extra esophageal manifestations like respiratory symptoms are being increasingly recognized. There are only very few studies on the prevalence of pulmonary symptoms in patients with erosive gastroesophageal reflux disease. Aim: The objective of the study was to determine the frequency of pulmonary symptoms in patients with erosive gastroesophageal reflux disease, Materials and Methods: This was a cross-sectional study done on 100 patients diagnosed based on upper gastrointestinal endoscopy findings. Patients were first interviewed about GERD symptoms using the GERD Health-Related Quality of Life questionnaire. Then the respiratory symptoms are assessed. Demographic details are recorded in a proforma. Pulmonary function tests were done on all the patients. Upper GI endoscopic findings are graded according to Los Angeles (LA) grading from A to D Results: The prevalence of pulmonary symptoms was 60%. The most prevalent symptom was a cough, then followed by dyspnoea on exertion, chest pain, wheezing, and snoring. There was a significant association found between LA grading and pulmonary symptoms like wheezing, cough, chest pain, and hoarseness of voice. No significant association was found between GERD duration and pulmonary symptoms. There was a statistically significant association found between LA grading and pulmonary function test. No association was found between quality of life scoring and pulmonary symptoms. Conclusion: There was a high prevalence of pulmonary symptoms in patients with erosive gastroesophageal reflux disease. Erosive GERD can affect pulmonary function according to severity. There was no association between prolonged GERD and pulmonary symptoms.
ABSTRACT
Background: Gastroesophageal reflux disease (GERD) is a spectrum of disease usually producing symptoms of heartburn and acid regurgitation. Its prevalence in general population is about 12–17% worldwide. There are many suggested risk factors for GERD. Aim and Objective: This study was conducted to find out whether smoking, diabetes mellitus (DM), and obesity are risk factors of GERD and to find out the extraesophageal symptoms of GERD. Materials and Methods: This is a case–control study matched for age done in 46 GERD patients who were cases and 92 subjects with dyspepsia who were not having GERD as controls. The statistical analysis was done to find out proportions and odds ratio (OR) with 95% confidence interval (CI). Results: Most of the study subjects were in the age group of 40–49 years. About 59% were males. About 14% were smokers and 25% were diabetics. OR for smoking, DM, and obesity was 3.706, 5.571, and 3.618, respectively. About 28% of the GERD patients had easy tiredness. Conclusion: In this study, smoking and DM were found to be the risk factors of GERD based on OR with 95% CI. The most frequent extraesophageal symptom among GERD patients was found to be tiredness.
ABSTRACT
Gastroesophageal reflux disease (GERD) is a common digestive system disease with various symptoms or complications.Currently, pH monitoring is the most powerful technology to diagnose GERD, generally including the 24-hour dynamic esophageal pH monitoring, Bilitec bile reflux monitoring, 24-hour multichannel intraluminal impedance-pH monitoring, wireless capsule pH monitoring and oropharyngeal pH monitoring.This study aims to review the development and clinical application of pH monitoring technology in GERD.
ABSTRACT
Background: Obesity is an independent risk factor for gastroesophageal reflux disease (GERD), but the mechanism remains unclear. There are few studies focusing on the effectiveness of standard dose proton pump inhibitor (PPI) in treating obese GERD patients. Aims: To investigate the effect of obesity on esophageal motility and acid reflux in GERD patients and the efficacy of standard dose PPI in treating obese GERD patients. Methods: Patients who were initially diagnosed as GERD and met the inclusion criteria from January 2017 to October 2021 at Anhui Provincial Hospital were included in this study. The results of esophageal high-resolution manometry and 24 h esophageal pH-impedance monitoring before PPI treatment in patients with normal body mass index (BMI) and obesity (BMI≥28.0 kg/m
ABSTRACT
Noncardiac chest pain (NCCP) is defined as a recurrent, angina⁃like chest pain after cardiac causes are excluded. It is a common and challenging problem in clinical practice that requires appropriate assessment to identify the underlying origin of the symptom. Gastroesophageal reflux disease (GERD), esophageal dysmotility and functional chest pain are the three main causes of NCCP. GERD is the most common cause of NCCP and should be evaluated first. Proton pump inhibitor (PPI) test, upper gastrointestinal endoscopy, 24 ⁃ hour esophageal pH ⁃ impedance monitoring are used to identify GERD⁃induced NCCP. High⁃resolution esophageal manometry is the main tool to identify esophageal dysmotility in non⁃GERD⁃related NCCP. Diagnosis of functional chest pain requires a negative cardiac workup, no response to PPI test, as well as no obvious abnormalities in upper gastrointestinal endoscopy with mucosal biopsy, esophageal pH ⁃ impedance monitoring and esophageal manometry. Treatment of NCCP is tailored according to the underlying mechanism that is responsible for the chest pain. PPI for GERD ⁃ related NCCP and smooth muscle relaxants for esophageal dysmotility are very commonly prescribed. Endoscopic and surgical interventions can also be considered in GERD and esophageal dysmotility related NCCP. For patients with functional chest pain, neuromodulators, mainly the antidepressants are the cornerstone of therapy.
ABSTRACT
Gastroesophageal reflux disease (GERD) is a common digestive disease characterized by heartburn and acid reflux. In recent years, many studies have shown that esophageal hypersensitivity is an important pathophysiological mechanism involved in the occurrence and development of heartburn. Esophageal sensory receptors including transient receptor potential vanilloid 1 (TRPV1), prostaglandin E
ABSTRACT
Background: The laryngopharyngeal symptoms of gastroesophageal reflux disease (GERD) include hoarseness, foreign body sensation, chronic cough, dysphagia, etc. Its pathogenic mechanisms and reflux characteristics may be different from those of GERD patients simply with typical esophageal symptoms. Aims: To explore the clinical characteristics of GERD patients complicated with laryngopharyngeal symptoms. Methods: Fifty-nine patients having a gastroesophageal reflux disease questionnaire (GerdQ) score ≥8 and abnormal reflux identified by 24 h esophageal impedance-pH monitoring were selected from the outpatients at the First Affiliated Hospital of Nanjing Medical University from January 2019 to December 2021. Twenty-nine cases simply with typical esophageal symptoms were allocated into typical symptom group, and 30 cases complicated with laryngopharyngeal symptoms were allocated into laryngopharyngeal reflux (LPR) group. The general information, results of gastroscopy, 24 h esophageal impedance - pH monitoring and esophageal manometry, as well as the efficacy of proton pump inhibitor (PPI) were collected and compared between the two groups. Results: The proportion of esophagitis in GERD patients in typical symptom group was significantly increased than that in LPR group (P<0.05), while the values of mean nocturnal baseline impedance at 7-3 cm above lower esophageal sphincter (LES) were significantly lower (all P<0.05). Compared with typical symptom group, increased frequency of weak acid reflux, prolonged mean acid clearance time, higher LES relaxation rate, lower velocity of peristaltic waves at 11-7 cm above LES, and poor efficacy of PPI treatment were observed in LPR group (all P<0.05). The severity of heartburn was positively correlated with the percentage of total acid exposure time and DeMeester score (all P<0.05); while the severity of foreign body sensation was positively correlated with the frequency of weak acid reflux and mean time of acid clearance (all P<0.05). Conclusions: The esophageal mucosal injury was mild in GERD patients complicated with laryngopharyngeal symptoms. Laryngopharyngeal symptoms are more likely to be associated with the decreased acid clearance capacity due to esophageal body dysmotility. Strengthened acid suppression therapy should be recommended.
