This study investigated the use of fiberoptic endoscopic evaluation of swallowing (FEES) to both diagnose pharyngeal dysphagia and make treatment recommendations in 17 consecutive patients with a new diagnosis of amyotrophic lateral sclerosis (ALS) and complaints of dysphagia. Ten of 17 (59%) patients exhibited pharyngeal dysphagia with aspiration or aspiration risk with clear liquids, i.e., 5 of 8 (63%) limb and 5 of 9 (56%) bulbar. If depth of bolus flow was a problem, thickened liquids and single, small bolus sizes were recommended. If bolus retention was a problem, a small clear liquid bolus after each puree or solid bolus was recommended to aid pharyngeal clearing. Five of 17 (30%) patients required multiple FEES evaluations because of disease progression. For the first time in patients with ALS, FEES was shown to be successful in assessing preswallow anatomy and physiology, diagnosing pharyngeal dysphagia, and providing objective data for appropriate therapeutic interventions to promote safer oral intake. Visual biofeedback provided by FEES was successful for both patient and family education and to investigate individualized therapeutic strategies that, if successful, can be implemented immediately. Serial FEES allows for objective monitoring of dysphagia symptoms and timely implementation of diet changes and/or therapeutic strategies to continue safer oral intake and maintain optimum quality of life.This research was supported, in part, by the McFadden, Harmon, and Mirikitani Endowments.  相似文献

This study investigated the effects, if any, that the presence of a tracheotomy tube has on the incidence of laryngeal penetration and aspiration in patients with a known or suspected dysphagia. This was a prospective, repeated-measure design study. A total of 37 consecutive patients with a tracheotomy tube underwent a fiberoptic endoscopic evaluation of swallowing (FEES). Patients were first provided with pureed food boluses with the tracheotomy tube in place. The tracheotomy tube was then removed and the tracheostoma site was covered with gauze and gentle hand pressure was applied. The patients were then evaluated without the tracheotomy tube in place with additional puree. Aspiration status was in agreement with and without the tracheotomy tube in place in 95% (35/37) of the patients. The two patients who demonstrated a different swallowing pattern with regard to aspiration demonstrated aspiration only when the tracheotomy tube was removed. Laryngeal penetration status was in agreement with and without the tracheotomy tube in place in 78% (29/37) of the patients. For the majority of the patients, the removal of the tracheotomy tube made no difference in the incidence of aspiration and/or laryngeal penetration. Results of this study do not support the clinical notion that the patient’s swallowing function will improve once the tracheotomy tube has been removed. Work for this project was completed at Marianjoy Rehabilitation Hospital, Wheaton, Illinois.  相似文献

This study prospectively investigated the incidence of vocal fold immobility, unilateral and bilateral, and its influence on aspiration status in a referred population of 1452 patients for a dysphagia evaluation from a large, urban, tertiary-care, teaching hospital. Main outcome measures included overall incidence of vocal fold immobility and aspiration status, with specific emphasis on age, etiology, and side of vocal fold immobility, i.e., right, left, or bilateral. Overall incidence of vocal fold immobility was 5.6% (81 of 1452 patients), including 47 males (mean age 55.7 yr) and 34 females (mean age 59.7 yr). In the subgroup of patients with vocal fold immobility, 31% (25 of 81) exhibited unilateral right, 60% (49 of 81) unilateral left, and 9% (7 of 81) bilateral impairment. Overall incidence of aspiration was found to be 29% (426 of 1452) of all patients referred for a swallow evaluation. Aspiration was observed in 44% (36 of 81) of patients presenting with vocal fold immobility, i.e., 44% (11 of 25) unilateral right, 43% (21 of 49) unilateral left, and 57% (4 of 7) bilateral vocal fold immobility. Left vocal fold immobility occurred most frequently due to surgical trauma. A liquid bolus was aspirated more often than a puree bolus. Side of vocal fold immobility and age were not factors that increased incidence of aspiration. In conclusion, vocal fold immobility, with an incidence of 5.6%, is not an uncommon finding in patients referred for a dysphagia evaluation in the acute-care setting, and vocal fold immobility, when present, was associated with a 15% increased incidence of aspiration when compared with a population already being evaluated for dysphagia.This research was supported in part by the McFadden, Harmon, and Mirikitani Endowments.  相似文献

This prospective study was undertaken to determine the accuracy of bedside clinical methods compared with fiberoptic endoscopic examination of swallowing (FEES) for detecting aspiration in acute stroke patients. Fifty patients underwent an examination of their ability to swallow 50 ml of water in 10-ml aliquots. Later their oxygen saturation levels before and after swallowing 10 ml of water were measured using a pulse oximeter. Oxygen desaturation of more than 2%, was considered to be clinically significant. All patients then underwent a FEES assessment by a speech therapist and were followed up during their inpatient stay for evidence of aspiration pneumonia. The oxygen desaturation test had a sensitivity of 76.9% and specificity of 83.3% (chi2 = 18.154, p = 0.00002), while the 50-ml water swallow test had a sensitivity of 84.6% and specificity of 75.0% (chi2 = 18.001, p = 0.00002). However, when these two tests were combined into one test called "bedside aspiration," the sensitivity rose to 100% with a specificity of 70.8% (chi2 = 27.9, p = 0.000001). Five (10%) patients developed pneumonia during their inpatient stay. The relative risk (RR) of developing pneumonia, if there was evidence of aspiration on FEES, was 1.24 (1.03 < RR < 1.49). We conclude that the oxygen desaturation test combined with the 50-ml water swallow test is suitable as a screening test to identify all acute stroke patients at risk of aspiration for further evaluation and management.  相似文献

The purpose of this study was to introduce a new method of bedside assessment of both the motor and sensory components of swallowing called fiberoptic endoscopic evaluation of swallowing with sensory testing (FEESST). This approach combines the established bedside endoscopic swallowing evaluation with a more recently described technique that allows objective determination of laryngopharyngeal (LP) sensory discrimination thresholds by delivering air pulse stimuli to the mucosa innervated by the superior laryngeal nerve via a flexible endoscope. A prospective study was conducted of FEESST in 20 healthy control subjects, mean age of 34 ± 11 years. LP sensory thresholds were defined as either normal (<4.0 mmHg air pulse pressure [APP]), moderate deficit (4.0–6.0 mmHg APP), or severe deficits (>6.0 mmHg APP). Subsequent to LP sensory testing, food of varying consistencies, mixed with green food coloring, was given and attention was paid to spillage, laryngeal penetration, pharyngeal residue, aspiration, and reflux. Therapeutic maneuvers such as postural changes and airway protection techniques were performed on each subject to determine if the assessed swallowing parameters were affected by maneuvers. All patients completed the study; all had normal LP sensory discrimination thresholds (2.9 ± 0.7 mmHg APP). There were no instances of spillage, laryngeal penetration, or aspiration. Two of 20 subjects had pharyngeal residue and 2 of 20 had reflux. Institution of therapeutic maneuvers resulted in a predictable change in the endoscopic view of the laryngopharyngeal anatomy. FEESST provides comprehensive, objective sensory and motor information about deglutition in the bedside setting and might have implications for the bedside diagnosis and management of patients with dysphagia.  相似文献

Abstract The overall objective of this pilot study was to determine blue dye test reliability and validity for the identification of aspiration of secretions, food, and/or drink in 50 simultaneously administered blue dye (BDT) and modified barium swallow (MBS) tests of tracheostomized individuals. With the MBS as an objective test of aspiration, BDT sensitivity and specificity identifying aspiration were less than 80% and 62%, respectively. Certain tracheostomy tube conditions and food consistencies were associated with more accurate BDT aspiration results than others. Characteristics of the aspiration episodes, interpretation of the results, and needs for further research are discussed.  相似文献

Background/AimsCurrently, the videofluoroscopic swallowing study (VFSS) is the standard tool for evaluating dysphagia. We evaluated whether the addition of endoscopist-directed flexible endoscopic evaluation of swallowing (FEES) to VFSS could improve the detection rates of penetration, aspiration, and pharyngeal residue, compared the diagnostic efficacy between VFSS and endoscopist-directed FEES and assessed the adverse events of the FEES.MethodsIn single tertiary referral center, a retrospective analysis of prospectively collected data was conducted. Fifty consecutive patients suspected of oropharyngeal dysphagia were enrolled in this study between January 2012 and July 2012.ResultsThe agreement in the detection of penetration and aspiration between VFSS and FEES of viscous food (κ=0.34; 95% confidence interval [CI], 0.15 to 0.53) and liquid food (κ=0.22; 95% CI, 0.02 to 0.42) was “fair.” The agreement in the detection of pharyngeal residue between the two tests was “substantial” with viscous food (κ=0.63; 95% CI, 0.41 to 0.94) and “fair” with liquid food (κ=0.37; 95% CI, 0.10 to 0.63). Adding FEES to VFSS significantly increased the detection rates of penetration, aspiration, and pharyngeal residue. No severe adverse events were noted during FEES, except for two cases of epistaxis, which stopped spontaneously without requiring any packing.ConclusionsThis study demonstrated that the addition of endoscopist-directed FEES to VFSS increased the detection rates of penetration, aspiration, and pharyngeal residue.  相似文献

Distinction between unilateral recurrent laryngeal nerve paralysis and Xth nerve paralysis is a rarely addressed issue in the literature. However, it may be crucial to examine the cause of the paralysis and to perform the appropriate investigation. The videoendoscopic swallowing study has been demonstrated to be a useful tool in assessing pharyngeal function. Since in unilateral Xth nerve paralysis the pharynx is impaired on the same side as the vocal fold immobility, it may be easily detected by videoendoscopic swallowing study. The rotation of the posterolateral pharyngeal wall toward the opposite side during swallowing is a sign of impaired motor pharyngeal branches. To demonstrate the usefulness of the videoendoscopic swallowing study in distinguishing unilateral Xth nerve from isolated recurrent nerve paralysis, a series of six patients were studied prospectively. Diagnosis of Xth nerve paralysis focused the investigation toward the high neck or the skull base area. Paralysis of the Xth nerve was suspected in all cases and diagnosis was achieved in five cases by the workup performed. Videoendoscopic swallowing study is a cost-effective and easily available tool which should be performed in all cases of vocal fold paralysis.  相似文献

Fiberoptic Endoscopic Evaluation of Dysphagia to Identify Silent Aspiration   总被引:3,自引:0,他引:3  
The traditional bedside dysphagia evaluation has not been able to identify silent aspiration because the pharyngeal phase of swallowing could not be objectively assessed. To date, only videofluoroscopy has been used to detect silent aspiration. This investigation assessed the aspiration status of 400 consecutive, at risk subjects by fiberoptic endoscopic evaluation of swallowing (FEES). Our study demonstrated that 175 of 400 (44%) subjects were without aspiration, 115 of 400 (29%) exhibited aspiration with a cough reflex, and 110 of 400 (28%) aspirated silently. No significant differences were observed for age or gender and aspiration status. The FEES, done at bedside, avoids irradiation exposure, is repeatable as often as necessary, uses regular food, can be videotaped for review, and is a patient-friendly method of identifying silent aspiration.  相似文献

Numerous studies have suggested that the clinical evaluation of swallowing fails to adequately identify those patients who aspirate or do not aspirate on a videofluoroscopic swallowing examination. These conclusions, however, are based on comparisons between swallowed materials that were not rheologically matched. The present study used a battery of rheologically matched test materials, involving thin and thick liquids and cohesive and adhesive semisolids. Using these test items, results from a clinical swallow evaluation were compared to the results of a videofluorographic evaluation using identical test materials. Results suggest that the use of three test materials, including thin and thick liquids given in volumes of 5 and 10 ml, demonstrated the strongest associations between cough on the clinical examination and aspiration on the videofluoroscopic examination.  相似文献

We describe a patient who suddenly developed dysphagia for liquids as the sole manifestation of stroke. Magnetic resonance imaging (MRI) revealed a right-sided infarction of the superior part of the anterior insula and a small portion of the adjacent medial frontal operculum. These findings confirm the role of the anterior insula as a critical area in humans with regard to the origin of dysphagia.

Dysphagia is common after stroke. Neuromuscular electrical stimulation (NMES) and fiberoptic endoscopic evaluation of swallowing (FEES) for the treatment of dysphagia have gained in popularity, but the combined application of these promising modalities has rarely been studied. We aimed to evaluate whether combined NMES, FEES, and traditional swallowing rehabilitation can improve swallowing functions in stroke patients with moderate to severe dysphagia. Thirty-two patients with moderate to severe dysphagia poststroke (≥3 weeks) were recruited. Patients received 12 sessions of NMES for 1 h/day, 5 days/week within a period of 2–3 weeks. FEES was done before and after NMES for evaluation and to guide dysphagic therapy. All patients subsequently received 12 sessions of traditional swallowing rehabilitation (50 min/day, 3 days/week) for 4 weeks. Primary outcome measure was the Functional Oral Intake Scale (FOIS). Secondary outcome measures included clinical degree of dysphagia, the patient’s self-perception of swallowing ability, and the patient’s global satisfaction with therapy. Patients were assessed at baseline, after NMES, at 6-month follow-up, and at 2-year follow-up. Twenty-nine patients completed the study. FOIS, degree of dysphagia, and patient’s self-perception of swallowing improved significantly after NMES, at the 6-month follow-up, and at the 2-year follow-up (p < 0.001, each compared with baseline). Most patients reported considerable satisfaction with no serious adverse events. Twenty-three of the 29 (79.3 %) patients maintained oral diet with no pulmonary complications at 2-year follow-up. This preliminary case series demonstrated that combined NMES, FEES, and traditional swallowing rehabilitation showed promise for improving swallowing functions in stroke patients with moderate-to-severe dysphagia. The benefits were maintained for up to 2 years. The results are promising enough to justify further studies.  相似文献

Evaluation of pharyngeal dysphagia with manofluorography   总被引:2,自引:0,他引:2  
The purpose of this paper is to analyze cervical dysphagia with a two-modality method using simultaneous fluoroscopy and solid-state computerized manometry (manofluorography). Manofluorography provides functional data that are not obtainable using barium swallow or standard manometry. Six examples of pharyngeal dysphagia are presented. They show that pharyngeal bolus transit is due to a pressure gradient. Two major generators of this gradient are tongue-driving pressure and the pharyngeal-esophageal segment negative pressure. Dysphagia is analyzed in terms of alteration of the pharyngeal pressure gradient.  相似文献

Vomiting after feeding is a symptom of gastroesophageal reflux (GER) and of eosinophilic esophagitis (EE), which are considered to be a cause of infant feeding disorder. The objective of the present study was to evaluate swallowing in children with feeding disorder manifested by vomiting after feeding. Using clinical and videofluoroscopic methods we studied the swallowing of 37 children with vomiting after feeding (mean age=15.4 months), and of 15 healthy children (mean age=20.5 months). In the videofluoroscopic examination the children swallowed a free volume of milk and 5 ml of mashed banana, both mixed with barium sulfate. We evaluated five swallows of liquid and five swallows of paste. The videofluoroscopic examination was recorded at 60 frames/s. Patients had difficulty during feeding, pneumonia, respiratory distress, otitis, and irritability more frequently than controls. During feeding, children with vomiting, choke were irritable, and refused food more frequently than controls, and during the videofluoroscopic examination the patients had more backward movement of the head than controls for both the liquid and paste boluses. There was no difference in the timing of oral swallowing transit, pharyngeal swallowing transit, or pharyngeal clearance between patients and controls. We conclude that children with vomiting after feeding may have difficulties in accepting feeding, although they have no alteration of oral and pharyngeal phases of swallowing.  相似文献

The objective of this study was to determine the inter- and intrarater reliability in evaluating videofluoroscopic swallowing studies (VFSS). Participants included 4 physicians (3 physiatrists and 1 internist) and 5 speech-language pathologists with at least 5 years experience in evaluating VFSS. The main outcomes of the study were reliability ratios of positive and negative tests in inter- and intrarater evaluations. Raters independently rated each of 20 VFSS on two separate occasions. Traits evaluated included oral stage impairment, aspiration, pharyngeal retention, and several functional components: timing of swallow onset, adequacy of velopharyngeal apposition, laryngeal elevation, epiglottic tilt, pharyngeal contraction, and pharyngoesophageal (PE) segment opening. Reliability varied widely depending on food type and the trait under evaluation. Inter- and intrarater reliability ratios did not differ widely. Reliability ratios values typically were highest (greater than 90%) for aspiration, especially with solid food, and lowest for the functional components. It was concluded that inter- and intrarater reliability in VFSS are adequate for evaluating oral stage, laryngeal penetration, and aspiration and pharyngeal retention, but questionable for functional components.  相似文献

The effect of effortful swallow on pharyngeal pressure and UES relaxation onsets and durations was examined. Eighteen adults, nine males and nine females (mean age = 27.9 yr), participated. Timing of pharyngeal pressure and onset and duration of UES relaxation were measured across ten trials of normal and ten trials of effortful swallows. Results revealed that manometric timing measurements are consistent across trials. The first and second statistical analyses investigated the pharyngeal pressure and UES relaxation onsets and durations, respectively. Both analyses identified a significant interaction of swallow type (i.e., effortful vs. normal) by manometric sensor location (p < 0.05). Across normal and effortful swallows, UES relaxation preceded pharyngeal pressure onsets, yet the rate of change (or degree of delay) varied across the sensors. Furthermore, the effortful swallow elicited longer pharyngeal pressure and UES relaxation durations, yet the pressure duration measured in the upper pharynx was significantly longer than that measured lower in the pharynx. These findings offer insight as to the potential positive and negative influence of the effortful swallow on pharyngeal timing.  相似文献

Abstract Elevation of the larynx during swallowing plays an important role in protecting the laryngeal inlet and in the opening of the upper esophageal sphincter (UES). The thyrohyoid (TH) muscle is the most important muscle for laryngeal elevation, and it is thought to be innervated by the thyrohyoid branch. However, in preliminary studies we found that laryngeal elevation was severely disturbed after sectioning of the pharyngeal branch of the vagus nerve (X-ph). In the present study, we examined the role of the X-ph in laryngeal elevation and the contribution of this nerve to UES pressure. Ten male rabbits under anesthesia were used. Sectioning of the X-ph not only abolished the electromyographic activities of the TH and cricopharyngeus (CP) muscles, it also greatly reduced the maximal value of laryngeal elevation during swallowing. On the other hand, sectioning of the hypoglossal nerve, which contains the thyrohyoid branch, produced no appreciable change in the electromyographic activity of either muscle and it reduced the maximal value of the elevation only slightly. These results indicate that the X-ph innervates the TH and CP muscles and suggest that the X-ph plays an important role in elevating the larynx and in regulating the UES pressure in rabbits.  相似文献

The ability to measure normality and abnormality and to accurately assess true changes in swallowing function over time, is important for the management of dysphagia. Despite this, there is a paucity of information regarding the stability and reliability of measurements tools used for dysphagia research. As both head and neck (H&N) cancer and its treatment(s) have been shown to significantly affect deglutitive tongue function, it is important that we have a reliable method to measure swallowing tongue function in this population. In this study we evaluate the reliability and stability of oro-lingual swallowing pressures captured from H&N cancer patients and from healthy, age- and gender-matched controls using the Kay Swallowing Workstation (KSW) fixed, three-transducer tongue pressure array. Significant differences between the two samples (H&N cancer and controls), with respect to mean peak oro-lingual pressures were recorded during swallowing. Furthermore, reliability of these measures was lower in H&N cancer patients. These differences highlight the importance of obtaining information about the reliability of dysphagia assessment tools with the specific population with whom they will be used.

This study used Fiberoptic Endoscopic Evaluation of Swallowing (FEES(R)) to assess the reliability of the Penetration-Aspiration Scale (PAS) using 79 swallows and four judges in a replication of a study using videofluoroscopy (VFSS). The swallows were diagnosed using FEES, which allowed for comparison between the two techniques. The findings indicated that all categories of the PAS achieved adequate reliability, both on intrajudge and interjudge assessments. Reliabilities, with the exception of Scale Score 7, were higher in this study than in the original study by Rosenbek and associates. Data analysis indicated that judges were more highly consistent on second ratings compared with their original ratings, indicating a learning curve on the PAS. In addition, findings suggested that the FEES was more reliable on assessing penetration than VFSS, but that VFSS was more reliable on the assessment of the various severities of aspiration. The two techniques were equally effective in discriminating between penetration and aspiration. This study found that FEES was just as reliable as VFSS when using the PAS.  相似文献
