Oesophageal dysphagia: a stepwise approach to diagnosis and management

ESSD-ESGAR best practice position statements on the technical performance of videofluoroscopic swallowing studies in adult patients with swallowing disorders

OBJECTIVES

Videofluoroscopic swallowing studies (VFSS) remain the gold standard for the instrumental assessment of oropharyngeal swallowing disorders alongside flexible endoscopic evaluation of swallowing (FEES), requiring a high standard of quality and correct implementation. The current best practice position statements aim to guide the clinical practice of VFSS in individuals experiencing swallowing disorders.

MATERIALS AND METHODS

An international expert consensus panel with expertise in oropharyngeal dysphagia, comprised of radiologists, speech-language therapists, otolaryngologists, and other professionals in the field, convened by the European Society of Swallowing Disorders (ESSD) and the European Society of Gastrointestinal and Abdominal Radiology (ESGAR), developed best practice position statements. They were established using an online Delphi methodology involving an online panel discussion and item preparation and three consecutive rounds. Consensus was reached when ≥ 80% of the participants agreed on a specific recommendation.

RESULTS

Eighteen best practice position statements were formulated, thereby establishing standard recommendations on the technical performance of VFSS. They cover VFSS planning, correct implementation, documentation, radiation protection, equipment and maintenance, and education and training.

CONCLUSION

These position statements summarise the panel's deliberations and recommendations in performing VFSS, representing the agreed consensus of experts from ESSD and ESGAR. They provide a structured framework for optimising and standardising the performance of VFSS in patients with swallowing disorders.

KEY POINTS

Question Significant regional and national differences in clinical practice when performing VFSS highlight the need for interdisciplinary recommendations to optimise patient care. Findings Eighteen statements were developed by representatives of the ESSD and the ESGAR. Clinical relevance These best practice position statements on the technical performance of VFSS may serve as a basis for standardising the procedure and ensuring high-quality service.

Dysphagia

Dysphagia, or difficulty swallowing, has significant impacts on patients' quality of life. A thorough history and physical examination can provide important information to determine if dysphagia is originating from oropharyngeal or esophageal causes. Identifying the underlying pathology contributing to dysphagia allows for optimal treatment and improved quality of life.

Cross-cultural adaptation and validation of Dysphagia Handicap Index in Bangladesh

The Dysphagia Handicap Index (DHI) is commonly utilized for evaluating how dysphagia impacts the quality of life (QoL) of patients across physical, functional, and emotional dimensions. The primary aim of the research was to linguistically validate and culturally adapt the DHI to the Bangla version. A cross-sectional study design was chosen, with Beaton's protocol as the guiding framework for validating and adapting the DHI. It has followed a systematic process of forward translation, participation in expert discussions, and subsequent back translation to obtain a reviewed version. The Bangla version, DHI-Ban, was administered purposefully to 50 dysphagia patients in the Clinical Speech and Language Therapy (SLT) Department of the Centre for the Rehabilitation of the Paralyzed (CRP) and was also administered to 50 healthy individuals for comparison. Of the fifty, eighteen dysphagia subjects were assigned again after two weeks for the retest. The DHI-Ban demonstrated strong internal consistency (Cronbach's α = 0.89) and good test-retest reproducibility (ICC = 0.86). The Spearman test confirmed significant construct validity (p < 0.01), and the Wilcoxon test identified significant differences (p < 0.001) between patients and healthy individuals. Feedback from participants was also taken into account for acceptance and clarity. In conclusion, the adapted DHI-Ban has emerged to be a reliable patient-reported tool for assessing dysphagia in Bangla-speaking individuals. Incorporating the Bangla language framework facilitates its comprehension and effectiveness, further solidifying its reliability.

A survey of dysphagia services practice in China

BACKGROUND

Dysphagia services have only recently been formalised within Chinese health services. There has been no comprehensive evaluation of all aspects of dysphagia services practice in China.

AIMS

To provide a profile for the dysphagia practice in China by assessing various facets of dysphagia services.

METHODS AND PROCEDURES

This is a survey study carried out from December 2022 to May 2023 online in China. One hundred fifty-nine respondents comprising doctors, nurses or therapists involved in the field of dysphagia rehabilitation completed a questionnaire via Sojump. The questionnaire included dichotomous (e.g., yes/no) and multiple-choice questions related to participants' general information and their provision of dysphagia management services. Results were analysed descriptively and the differences among different levels of hospitals were analysed.

OUTCOMES AND RESULTS

Approximately two-thirds of hospitals (67.9%) started dysphagia services within the last 5 years. A significant difference in the initiation of dysphagia rehabilitation was observed across different hospital levels (χ2  = 32.70;p < 0.001). Routine dysphagia screening was a standard practice in most hospitals (71.7%), with the most frequently employed screening method being the water swallow test (95.6%). Clinical swallowing evaluation emerged as the preferred initial assessment method (80.5%) and the most utilised assessment method (91.8%). Video fluoroscopic swallow study and flexible endoscopic evaluation swallowing were used by 22.7% and 12.6% of respondents. A significant difference was observed in the choice of assessment methods across hospitals of different levels (χ2 = 43.397; p < 0.001). The majority of respondents (53.5%) primarily employed rehabilitation as the main intervention method (76%-100%). Most respondents indicated that they would reevaluate patients after treatment (74.8%) and reported routine follow-up with patients (60.4%).

CONCLUSIONS AND IMPLICATIONS

Despite the relatively recent development of dysphagia management in China, the practice patterns uncovered in this study are broadly consistent with Chinese guidelines and consensus. However, the use of instrumental assessments remains low, resulting in a lack of objective evaluation of patient conditions and outcomes. There is a need for policy and resource support in the field of dysphagia rehabilitation in China.

WHAT THIS PAPER ADDS

What is already known on this subject Assessment and treatment methods for dysphagia are various across different patients, medical facilities and settings. There has been no comprehensive evaluation of all aspects of dysphagia rehabilitation practice in China. What this study adds to existing knowledge The study assessed various facets of dysphagia rehabilitation in China through an online survey. We found that the relatively recent development of dysphagia management in China, but the practice patterns uncovered in this study are broadly consistent with Chinese guidelines and consensus. Variations in practice patterns between hospitals of different levels may be attributed to resource constraints and patient needs. Besides, while rehabilitation exercises are the primary intervention method for dysphagia in China, the assessment largely centres on clinical swallowing evaluation. The use of instrumental assessments remains low, resulting in a lack of objective evaluation of patient conditions and outcomes. What are the clinical implications of this work? The study assessed various facets of dysphagia rehabilitation in China, and the results indicate that the use of instrumental assessments needs to be improved and there is a need for policy and resource support in the field of dysphagia rehabilitation in China.

Automatic Clinical Assessment of Swallowing Behavior and Diagnosis of Silent Aspiration Using Wireless Multimodal Wearable Electronics

Dysphagia is more common in conditions such as stroke, Parkinson's disease, and head and neck cancer. This can lead to pneumonia, choking, malnutrition, and dehydration. Currently, the diagnostic gold standard uses radiologic imaging, the videofluoroscopic swallow study (VFSS); however, it is expensive and necessitates specialized facilities and trained personnel. Although several devices attempt to address the limitations, none offer the clinical-grade quality and accuracy of the VFSS. Here, this study reports a wireless multimodal wearable system with machine learning for automatic, accurate clinical assessment of swallowing behavior and diagnosis of silent aspirations from dysphagia patients. The device includes a kirigami-structured electrode that suppresses changes in skin contact impedance caused by movements and a microphone with a gel layer that effectively blocks external noise for measuring high-quality electromyograms and swallowing sounds. The deep learning algorithm offers the classification of swallowing patterns while diagnosing silent aspirations, with an accuracy of 89.47%. The demonstration with post-stroke patients captures the system's significance in measuring multiple physiological signals in real-time for detecting swallowing disorders, validated by comparing them with the VFSS. The multimodal electronics can ensure a promising future for dysphagia healthcare and rehabilitation therapy, providing an accurate, non-invasive alternative for monitoring swallowing and aspiration events.

Oesophageal fluoroscopy in adults-when and why?

Oesophageal fluoroscopy is a radiological procedure that uses dynamic recording of the swallowing process to evaluate morphology and function simultaneously, a characteristic not found in other clinical tests. It enables a comprehensive evaluation of the entire upper gastrointestinal tract, from the oropharynx to oesophagogastric bolus transport. The number of fluoroscopies of the oesophagus and the oropharynx has increased in recent decades, while the overall use of gastrointestinal fluoroscopic examinations has declined. Radiologists performing fluoroscopies need a good understanding of the appropriate clinical questions and the methodological advantages and limitations to adjust the examination to the patient's symptoms and clinical situation. This review provides an overview of the indications for oesophageal fluoroscopy and the various pathologies it can identify, ranging from motility disorders to structural abnormalities and assessment in the pre- and postoperative care. The strengths and weaknesses of this modality and its future role within different clinical scenarios in the adult population are discussed. We conclude that oesophageal fluoroscopy remains a valuable tool in diagnostic radiology for the evaluation of oesophageal disorders.

Assessing Adhesiveness Levels in a Dysphagia Diet for Older Adults

BACKGROUND

Viscosity is a common focus in the diet of patients with dysphagia. However, adhesiveness is an equally significant property that can affect swallowing function, even in semi-solid foods with similar levels of viscosity. The purpose of this study was to classify the adhesiveness of food into stages and determine whether these classifications are relevant to swallowing function.

METHODS

This study included 30 healthy elderly adults aged 65 years. After categorizing adhesiveness into three levels based on the results of the sensory test, 30 participants were asked to swallow representative foods at each level. A videofluoroscopic swallowing study (VFSS) was performed to determine the presence or absence of pharyngeal residues based on the level of adhesiveness. The chi-square test was used to verify whether there was a difference in remnants according to the level of adhesiveness, and significance was judged with a p-value of less than 0.05.

RESULTS

Adhesiveness was categorized into three distinct levels: level 1 (0-4 mJ), level 2 (4-18 mJ), and level 3 (>18 mJ). Upon examining the subjects presenting with residual material, we observed three cases of level 1 adhesiveness, 16 cases of level 2, and 25 cases of level 3. The chi-square test was used to assess the statistical significance between the levels, revealing a significant difference with a p-value < 0.0001.

CONCLUSIONS

We presented the level of adhesiveness by dividing it into three stages and proved that it is meaningful in relation to the swallowing function. Selecting and recommending foods with an appropriate level of adhesiveness will help enhance swallowing safety in older adults.

Current Approach to Dysphagia: A Review Focusing on Esophageal Motility Disorders and Their Treatment

Background

Dysphagia is a prevalent condition which may severely impact the patient's quality of life. However, there are still lacking standardized therapeutic options for esophageal motility disorders.

Summary

Dysphagia is defined as a subjective sensation of difficulty swallowing which can result from oropharyngeal or esophageal etiologies. Regarding esophageal dysphagia, after excluding structural causes and esophageal mucosal lesions, high-resolution manometry (HRM) is the gold standard for the diagnosis of esophageal motility disorders. HRM has not only improved the sensitivity for detecting achalasia but has also expanded our understanding of spastic and hypomotility disorders of the esophageal body. The Chicago Classification v4.0 uses a hierarchical approach and provides a standardized diagnosis of esophageal motility disorders, allowing a tailored therapeutic approach. Dysphagia is often a long-term health problem that broadly impacts health and well-being and leads to physical and psychosocial disability, namely, malnutrition and aspiration pneumonia, as well as social isolation, depression, and anxiety. Apart from achalasia, most esophageal motility disorders tend to have a benign long-term course with symptoms of dysphagia and noncardiac chest pain that can improve significantly over time. Patient-reported outcomes (PROs) are self-assessment tools that capture the patients' illness experience and help providers better understand symptoms from the patients' perspective. Therefore, PROs have a critical role in providing patient-centered care.

Key Messages

Motility disorders should be ruled out in the presence of nonobstructive esophageal dysphagia, and treatment options should be considered according to the severity of symptoms reported by the patient.

Practical multidisciplinary framework for the assessment and management of patients with unexplained chronic aerodigestive symptoms

OBJECTIVE

Patients experiencing unexplained chronic throat symptoms (UCTS) are frequently referred to gastroenterology and otolaryngology outpatient departments for investigation. Often despite extensive investigations, an identifiable structural abnormality to account for the symptoms is not found. The objective of this article is to provide a concise appraisal of the evidence-base for current approaches to the assessment and management of UCTS, their clinical outcomes, and related healthcare utilisation.

DESIGN

This multidisciplinary review critically examines the current understanding of aetiological theories and pathophysiological drivers in UCTS and summarises the evidence base underpinning various diagnostic and management approaches.

RESULTS

The evidence gathered from the review suggests that single-specialty approaches to UCTS inadequately capture the substantial heterogeneity and pervasive overlaps among clinical features and biopsychosocial factors and suggests a more unified approach is needed.

CONCLUSION

Drawing on contemporary insights from the gastrointestinal literature for disorders of gut-brain interaction, this article proposes a refreshed interdisciplinary approach characterised by a positive diagnosis framework and patient-centred therapeutic model. The overarching aim of this approach is to improve patient outcomes and foster collaborative research efforts.

Translation, Cultural Adaptation and Validation of "PROMIS GI - Disrupted Swallowing" Scale for the Portuguese Language

INTRODUCTION

Dysphagia is a prevalent condition (20%), and occurs more frequently in women and in older people. It negatively impacts innumerous aspects of patient's personal and professional lives. Patient-reported outcomes allow patients to directly quantify their experience regarding dysphagia and evaluate its true impact on quality of life. Among the scales available, Patient-Reported Outcomes Measurement Information System Gastrointestinal (PROMIS GI) Disrupted Swallowing stands out because it is a robust instrument that can be applied regardless of the type and etiology of dysphagia. The aim of this study was to translate, culturally adapt and validate PROMIS GI Disrupted Swallowing scale for the Portuguese-speaking population.

MATERIAL AND METHODS

Firstly, the seven items of the scale were translated and transculturally reviewed following the systematic method proposed by the Functional Assessment of Chronic Illness Therapy (FACIT). Afterwards, the pre-test version of the questionnaire was administered to a convenience sample (n = 6) for semantic evaluation, with the aim of detection and subsequent correction of possible problems in the translation. The final translated and certified version of the scale was administered to 200 voluntary adult participants (n = 123 healthy; n = 77 dysphagia) in Portugal, for evaluation of reliability and validity.

RESULTS

The Portuguese version of PROMIS GI Disrupted Swallowing presented acceptable internal consistency (coefficient of Cronbach's α of 0.919) and adequate test-retest reliability (intraclass correlation coefficient of 0.941). The translated version of the scale revealed a strong correlation with both Eckardt score (p < 0.001; ρ = 0.782) and the quality-of-life questionnaire EuroQol-5D (p < 0.001; ρ = -0.551), demonstrating evidence of convergent validity.

CONCLUSION

The Portuguese version of PROMIS GI Disrupted Swallowing scale presented conceptual, semantic, cultural and measurement equivalence relatively to the original items. The results attained demonstrated that the translation of this scale to Portuguese is reliable and valid for use both in clinical practice and for research purposes.

Dysphagia

Dysphagia is an important clinical symptom that increases in prevalence with age. Both oropharyngeal and esophageal processes can contribute to dysphagia, and these can be differentiated with a careful history. Neuromuscular processes are more prevalent than structural causes in oropharyngeal dysphagia, therefore, investigation should start with a modified barium swallow. In contrast, structural processes dominate in esophageal dysphagia, and endoscopy can offer biopsy and therapy by way of dilation. Manometry is performed for esophageal dysphagia when no structural etiology is found. Specific management of dysphagia is dependent on the etiology and mechanism of dysphagia.

Reduced masticatory function predicts gastroesophageal reflux disease and esophageal dysphagia in patients referred for upper endoscopy: A cross-sectional study

BACKGROUND

The role of mastication on gastroesophageal reflux disease (GERD) is unknown.

AIMS

To assess whether reduced masticatory function predicts GERD and esophageal dysphagia in patients investigated with upper endoscopy.

METHODS

In this cross-sectional study, 179 adult patients referred for elective upper gastrointestinal endoscopy agreed to participate. Before endoscopy, an expert dentist performed an oral examination and scored chewing function in three levels (normal, regular, and reduced). Patients replied questionnaires for assessment of GERD (heartburn, regurgitation, and dysphagia), xerostomia, and mastication (normal, regular, and reduced). Poor chewing was defined when either oral examination or mastication questionnaire rated the chewing function as reduced. Associations of mastication with GERD and dysphagia were estimated using Poisson regression.

RESULTS

Eleven patients were excluded. Among 168 analyzed (aging 49.8 ± 15.5 years; 58.9% women), 46 had reduced masticatory function (27.4%), and 122 had regular/normal mastication (72.6%). Reduced mastication was associated with GERD [PR = 1.38 (95%CI 1.12 - 1.70)], adjusting for age, and with esophageal dysphagia [PR = 2.03 (95%CI 1.02 - 4.04)], adjusting for age and xerostomia.

CONCLUSIONS

In outpatients referred for upper gastrointestinal endoscopy, reduced masticatory function defined by an expert dentist may be a risk factor for GERD and esophageal dysphagia.

Dysphagia and Swallowing Disorders

Dysphagia, defined as impairment of the swallowing process, is a common symptom and can be a significant source of morbidity and mortality in the general population. This article summarizes the causes of the condition, its prevalence, and the consequences and costs of untreated dysphagia. The aim of this article is to provide a framework for the general internist in assessing, diagnosing, and managing dysphagia in an adult patient. Basic diagnostic screening procedures and techniques for management are emphasized. A basic treatment pathway based on cause is provided for reference.

A case of lymphocytic esophagitis in a woman with multiple allergies

Background

Lymphocytic esophagitis is a newly recognized entity of unknown origin. Dysphagia is defined as difficulty swallowing and represents a common symptom in the general population with a prevalence of approximately 20%. Chronic inflammation of the esophageal wall may manifest itself clinically and endoscopically, mimicking inflammation of another origin. However, little is known about the pathogenesis of the disease, as patients are seldom suspected and rarely diagnosed with lymphocytic esophagitis.

Case presentation

Here, we present a rare case of lymphocytic esophagitis in a patient with multiple allergies and suspected eosinophilic esophagitis. A 28-year-old woman with polyvalent sensitization to food and inhalant allergens presented with intermittent dysphagia, a sensation of a foreign body in the throat, itchiness of the oral cavity after ingesting certain foods, heartburn, and prolonged chewing time. A skin prick test showed positive results for birch-tree, alder, hazel, and rye pollen, as well as house dust mites. Apart from obesity (BMI 30 kg/m²), multiple pustules and excoriations on the skin, her physical examination was insignificant. Esophagogastroduodenoscopy (EGD) was performed revealing full-length but discrete trachealization of the esophagus. A barium swallow test showed slowing of esophageal peristalsis in the recumbent position. No esophageal pathology was observed. A histopathological analysis of mucosal samples revealed slight hyperplasia of the basal layer of the esophagus, and the stomach showed changes typical of chronic gastritis.

Conclusions

In summary, this clinical case illustrates that lymphocytic esophagitis, as a newly recognized entity, should be considered in the differential diagnosis of chronic dysphagia. Additionally, when treating allergic patients, clinicians should be aware that lymphocytic esophagitis, distinct from eosinophilic esophagitis, should be considered in the diagnosis of patients with atopy and upper gastrointestinal symptoms.

A practical approach to the evaluation and management of gastrointestinal symptoms in patients with systemic sclerosis

The gastrointestinal (GI) tract is the most commonly affected internal organ system in systemic sclerosis (SSc). SSc may lead to impaired function in any region of the GI tract, from the esophagus to the anorectum, which causes significant morbidity as well as mortality in patient subsets. Given the low prevalence of SSc in the community, many rheumatologists may not have a systematic framework for diagnosing or treating the GI complaints in this disease. These practice recommendations aim to summarize and consolidate the current guidelines from the fields of gastroenterology and rheumatology and establish a symptom-based framework for diagnosis and management based on available evidence in the literature. Subject areas that are in need of additional research are also identified.

[Endoscopic Management of Dysphagia]

Dysphagia is difficulty in swallowing that can be caused by a number of disorders that involve either the oropharynx or the esophagus. Specific endoscopic treatment for dysphagia depends on its etiology, whether the dysphagia is caused by mechanical narrowing or a motor disorder. Variable endoscopic treatment strategies can be used to manage dysphagia. Patient with dysfunction of the upper esophageal sphincter may benefit from esophageal dilationor injection of botulinum toxin. Pneumatic balloon dilation, injection of botulinum toxin, peroral endoscopic myotomy can be considered as treatment options for esophageal motility disorders. Endoscopic dilation is the treatment choice of esophageal stricture, while intraluminal steroid injection and temporary stent can be considered in refractory benign esophageal stricture. Self-expandable metal stent insertion can be considered for dysphagia with malignant cause.

Dysphagia Evaluation: The Added Value of Concurrent MBS and Esophagram

OBJECTIVES/HYPOTHESIS

Dysphagia is associated with increased mortality and healthcare costs. The modified barium swallow study (MBS) is the gold standard in assessing oropharyngeal dysphagia, but does not evaluate the esophagus. A barium esophagram can visualize the esophagus but does not evaluate the oropharyngeal swallow, nor does it utilize the expertise of speech and language pathologists. Providers may order one or both studies yet still risk missing critical pathology.

STUDY DESIGN

Retrospective cohort study.

METHODS

A retrospective chart review was conducted at an academic medical center between January 2016 and June 2019 focused on patients who had both MBS and esophagram as imaging for dysphagia evaluation. Analysis determined whether MBS and esophagram performed concomitantly improved diagnostic clarity.

RESULTS

A total of 5,183 patients underwent 6,066 swallow studies for dysphagia in the study period. Of which, 124 of these patients had concurrent MBS and esophagram. 10.5% of concurrent studies demonstrated a congruent negative evaluation. 59.7% of patients had an unremarkable MBS or esophagram paired with abnormal findings within the corresponding esophagram or MBS, respectively. 29.8% had both MBS and esophagrams that demonstrated an abnormality, but with unique pathologies identified by each study. In total, 85.1% of unremarkable MBS or esophagrams were paired with abnormal findings in the corresponding esophagram or MBS, respectively.

CONCLUSION

Selection of diagnostic testing is variable among providers and may be influenced by healthcare systems. This analysis revealed that MBS and esophagrams provide unique diagnoses. Concurrent MBS and esophagrams may improve diagnostic accuracy, yet minimize additional studies. National practices around dysphagia diagnostics are inconsistent and would benefit from standardization.

Gastroesophageal Reflux Disease: A Review

IMPORTANCE

Gastroesophageal reflux disease (GERD) is defined by recurrent and troublesome heartburn and regurgitation or GERD-specific complications and affects approximately 20% of the adult population in high-income countries.

OBSERVATIONS

GERD can influence patients' health-related quality of life and is associated with an increased risk of esophagitis, esophageal strictures, Barrett esophagus, and esophageal adenocarcinoma. Obesity, tobacco smoking, and genetic predisposition increase the risk of developing GERD. Typical GERD symptoms are often sufficient to determine the diagnosis, but less common symptoms and signs, such as dysphagia and chronic cough, may occur. Patients with typical GERD symptoms can be medicated empirically with a proton pump inhibitor (PPI). Among patients who do not respond to such treatment or if the diagnosis is unclear, endoscopy, esophageal manometry, and esophageal pH monitoring are recommended. Patients with GERD symptoms combined with warning symptoms of malignancy (eg, dysphagia, weight loss, bleeding) and those with other main risk factors for esophageal adenocarcinoma, such as older age, male sex, and obesity, should undergo endoscopy. Lifestyle changes, medication, and surgery are the main treatment options for GERD. Weight loss and smoking cessation are often useful. Medication with a PPI is the most common treatment, and after initial full-dose therapy, which usually is omeprazole 20 mg once daily, the aim is to use the lowest effective dose. Observational studies have suggested several adverse effects after long-term PPI, but these findings need to be confirmed before influencing clinical decision making. Surgery with laparoscopic fundoplication is an invasive treatment alternative in select patients after thorough and objective assessments, particularly if they are young and healthy. Endoscopic and less invasive surgical techniques are emerging, which may reduce the use of long-term PPI and fundoplication, but the long-term safety and efficacy remain to be scientifically established.

CONCLUSIONS AND RELEVANCE

The clinical management of GERD influences the lives of many individuals and is responsible for substantial consumption of health care and societal resources. Treatments include lifestyle modification, PPI medication, and laparoscopic fundoplication. New endoscopic and less invasive surgical procedures are evolving. PPI use remains the dominant treatment, but long-term therapy requires follow-up and reevaluation for potential adverse effects.

Dysphagia from a neurogeriatric point of view : Pathogenesis, diagnosis and management

Dysphagia is becoming increasingly more common in aging societies and, like the classical geriatric syndromes, it is a relevant functional impairment. The prevalence of dysphagia is highest in the group of old patients with neurological disorders, particularly in patients with stroke, dementia and Parkinson's disease. In the various neurological diseases of older people disease-specific factors often have a decisive influence on the clinical management of dysphagia. In addition, the concept of primary and secondary presbyphagia plays an important role in understanding age-related dysphagia. Whereas at the organ level of the International Classification of Functioning, Disability and Health (ICF) model, the diagnosis and treatment of dysphagia in neurogeriatrics have already made progress, more research is needed on the levels of activity/mobility, social environment, personal factors and the environment. This article summarizes the pathophysiological aspects as well as the current evidence for diagnosis and treatment of neurogeriatric dysphagia. Due to its high clinical relevance dysphagia should be added to the geriatric syndromes as "impaired swallowing".

Correlation Between Clinical Signs and High-resolution Manometry Data in Children

OBJECTIVES

High-resolution manometry (HRM) is the gold standard for diagnosis of esophageal motility disorders. However, clinical signs associated with these disorders are nonspecific, and it is difficult to correlate clinical signs with HRM data. The main objective of our study was to assess the positive predictive value (PPV) and negative predictive value (NPV) of each clinical sign, as well as their sensitivity and specificity in the diagnosis of esophageal motility disorders.

METHODS

This is a bicentric retrospective cohort study based on HRM data collected between May 2012 and May 2016. The studied symptoms were weight loss, feeding difficulties, swallowing disorders, dysphagia, food blockages, vomiting, gastroesophageal reflux disease (GERD), belching, and respiratory symptoms. HRM data were analyzed according to the Chicago Classification (3.0).

RESULTS

In total, 271 HRM data were analyzed, of which 90.4% showed abnormal results. HRM was well tolerated in 91% of the cases. The most common esophageal motility disorder was ineffective esophageal motility (38%). Weight loss was significantly associated (P = 0.003) with an abnormal HRM with a 96% PPV.

CONCLUSIONS

With nonspecific clinical signs suggesting an esophageal motility disorder, weight loss was a predictive sign of abnormal HRM results. HRM was well tolerated in pediatric patients, and ineffective esophageal motility appears to be the most frequent motility disorder in our cohort, as already observed in adult patient studies.

How to use Rome IV criteria in the evaluation of esophageal disorders

PURPOSE OF REVIEW

In 2016, the Rome IV process and criteria were published. They provide a system to standardize patient diagnostic requirements for clinical studies and pharmaceutical trials on functional gastrointestinal disorders (FGIDs), which are now called disorders of gut-brain interaction (DGBI). Although the Rome criteria have limitations in clinical practice, an understanding of the criteria can help clinicians to manage symptoms in patients with DGBI, and with organic diseases as well.

RECENT FINDINGS

In this report, the Rome IV criteria for esophageal DGBI, the updated algorithms for esophageal symptoms, and the multidimensional clinical profile (MDCP) are reviewed.

SUMMARY

The esophageal DGBI comprise functional esophageal chest pain, functional heartburn, globus, functional dysphagia, and the newly introduced reflux hypersensitivity. They are characterized by the presence of chronic symptoms attributed to the esophagus without evidence of esophageal structural, inflammatory, or motility abnormalities. Also, Rome IV suggests for the first time the possibility that functional heartburn or reflux hypersensitivity might overlap with gastroesophageal reflux disease. Accordingly, testing with endoscopy and biopsies, esophageal pH ± impedance monitoring and high-resolution esophageal manometry are necessary to establish esophageal DGBI diagnoses. Algorithms aid in this diagnostic process, and the MDCP that captures the full dimension of each patient's presentation is helpful in planning personalized treatment regimens.
