Application of fiberoptic endoscopic examination of swallowing combined with dye test in silent aspiration after stroke / 中国康复理论与实践

ObjectiveTo explore the diagnostic value of fiberoptic endoscopic examination of swallowing (FEES) combined with dye test in patients with post-stroke dysphagia and silent aspiration. MethodsFrom December, 2021 to June, 2022, 50 stroke patients in the Rehabilitation Department of Xuzhou Central Hospital were selected. They were assessed with FEES and videofluoroscopic swallowing study (VFSS), and compared. ResultsThe detection rate of aspiration was higher with FEES than with VFSS (χ2 = 7.000, P < 0.05), and especially for liquid food (χ2 = 4.000, P < 0.05). There was a good consistency when consuming paste food (κ = 0.941, P < 0.001) and solid food (κ = 0.779, P < 0.001). There was a good consistency in the food residue site between two methods (κ = 0.818, P < 0.001), as well as for all the three food types (κ ≥ 0.862, P < 0.001). There was no significant difference in the scores of Penetration Aspiration Scale of three food types between two methods (Z < 0.667, P > 0.05). ConclusionFEES combined with dye test can be used for evaluating silent aspiration after stroke.

Fiberoptic endoscopic evaluation of swallowing and the Brazilian version of the Eating Assessment Tool-10 in resistant hypertensive patients with obstructive sleep apnea

Abstract Objective: The aim of this study was to describe the prevalence and characteristics of OD through Fiberoptic Endoscopic Evaluation of Swallowing (FEES) and the Eating Assessment Tool-10 (EAT-10) in hypertensive patients with OSA, as well as to describe the sensitivity of EAT-10 for the detection of OD in this population. Methods: This study included a convenience sample in which 85 resistant hypertensive patients diagnosed with OSA in an university hospital participated. Participants were subjected to the EAT-10 (index test) and FEES (reference standard). Results: The median EAT-10 score was 2 (0-5.5). According to the FEES, 27 participants did not have dysphagia, 42 had mild dysphagia and 16 had mild to moderate dysphagia. The sensitivity of the EAT-10 was 70.7% (95% CI: 57.3-81.9) at a cutoff score ≤1, with a discriminatory power of 67.4% (p = 0.005). The most prevalent symptom in this population was "food stuck in the throat", while the most prevalent signs were delayed initiation of the pharyngeal phase of swallowing, premature bolus spillage and pharyngeal residue. Conclusion: In our study, the cutoff score for the EAT-10 for screening for OD in this population was ≥ 1. In conclusion, this population presented a high prevalence of dysphagia detected in FEES and its severity is associated with higher EAT-10 scores.

OBJECTIVE@#To observe the effect of acupuncture combined with regular treatment and swallowing function training on pharyngeal motor, sensory function and penetration-aspiration function in patients with dysphagia after stroke.@*METHODS@#A total of 60 patients with dysphagia after stroke were randomly divided into a control group and an observation group, 30 patients in each group. Both groups were treated with conventional treatment and swallowing function training; in addition, the observation group was treated with acupuncture at Lianquan (CV 23), Fengfu (GV 16), Yifeng (TE 17). All the treatments were given once a day, 5 days a week, for totally 4 weeks. In the two groups, the pharyngeal motor and sensory function, penetration-aspiration scores were evaluated by fiberoptic endoscopic evaluation of swallowing (FEES), and the Kubota water swallowing test scores were assessed before and after treatment, and the clinical effects were compared.@*RESULTS@#After treatment, the pharyngeal motor and sensory function in the two groups were all higher than those before treatment (P<0.05), and those in the observation group were better than the control group (P<0.05). After treatment, the penetration-aspiration scores and Kubota water swallowing test scores in the two groups were all lower than those before treatment (P<0.05), and those in the observation group were lower than the control group (P<0.05). The total effective rate was 93.3% (28/30) in the observation group, which was better than 73.3% (22/30) in the control group (P<0.05).@*CONCLUSION@#Acupuncture combined with regular treatment and swallowing training could improve the pharyngeal motor and sensory function, and penetration-aspiration scores in patients with dysphagia after stroke.

Influence of nape acupuncture therapy on swallowing function of patients with cerebral infarction / 解放军医学杂志

Objective To observe the influence of nape acupuncture therapy on swallowing function of patients with cerebral infarction. Methods Eighty patients with dysphagia after cerebral infarction were recruited and randomly allocated to the nape acupuncture group and the control group, 40 each group. Both groups were given general medicine therapy and swallowing functional training, while the nape acupuncture group was given nape acupuncture based on the control group, and fiberoptic nasopharyngoscopy was used for the swallowing function before and after treatment. Rosenbek Penetration-Aspiration Scale (PAS) score of 5ml pudding food, 5ml and 10ml liquid food, and the scores for bedside water-swallowing test and standardized swallowing assessment (SSA) were obtained. Before and after treatment, the differences between the two groups were identified respectively. Results After treatment, the scores of SSA and PAS of swallowing of 3 kinds of food in both groups were significantly improved compared with those before treatment (P<0.05). The improvement of SSA and PAS scores of 5ml and 10ml liquid food in the nape acupuncture group were superior to the control group (P<0.05). The total effective rate of the nape acupunture group was significantly higher than that of control group (χ2=5.00, P<0.05). Conclusion Nape acupuncture therapy may significantly improve the swallowing function of patients with dysphagia following cerebral infarction.

Advance in Fiberoptic Endoscopic Evaluation of Swallowing for Dysphagia (review) / 中国康复理论与实践

Application of fiberoptic endoscopic evaluation of swallowing (FEES) can accurately evaluate the static and dynamic anatomical structure of pharynx and larynx, the feeling of pharynx and larynx, secretion level, aspiration, residue and other important swallowing evaluation indexes, which is important for swallowing treatment and valuable for diagnosis of dysphagia.

Peri-Treatment Evaluation of Swallowing in Head and Neck Cancer Patients

Head and neck cancer patients are prone to dysphagia and aspiration, which are usually neglected due to treatment of the cancer itself. However, dysphagia and aspiration could cause malnutrition, dehydration, pneumonia, and moreover, have negative impact on the quality of life, morbidity, and mortality. Due to its multifactorial etiology, thorough clinical and instrumental evaluation are necessary. In managing head and neck cancer patients, it has become very important to identify the possibility of dysphagia and aspiration, and to start management as early as possible.

Effectiveness of Fiberoptic Endoscopic Evaluation of Swallowing (FEES) in Patients with Swallowing Disorders -A Systematic Review-

OBJECTIVE: The objective of this systematic review is to evaluate the safety and effectiveness of fiberoptic endoscopic evaluation of swallowing (FEES) for dysphagia patients. METHOD: We performed a systematic review of the literature. We searched Ovid-Medline(R), EMBASE(R) and Cochrane library(R) and Eight domestic databases including KoreaMed up to 19 April 2010. In addition, we added hand search. Searches were conducted without language restriction. We identified ten studies that met our eligibility criteria. Two reviewers independently extracted prespecified data from each study. Also reviewers assessed quality of each study. The qualities of these studies were assessed according to Scottish Intercollegiate Guidelines Network (SIGN) tool. RESULTS: Ten studies (nine diagnostic evaluation studies and one case series) were identified. The complication rate of FEES was 6% which was reported only one study as nose bleeding that did not need further treatment. The effectiveness of FEES was evaluated based on diagnostic accuracy, agreement rate with videofluoroscopy as a reference test. The sensitivities of FEES were 0.87~1.0 (penetration), 0.22~0.96 (aspiration), 0.68~0.91 (pharyngeal residue), and 0.75 (premature spillage) respectively. Specificities of FEES were 0.75~1.0 (penetration), 0.88~1.0 (aspiration), 0.86~1.0 (pharyngeal residue), and 0.56 (premature spillage) respectively. Agreement rate with VFFS were 85~100% (penetration), 82.3~100% (aspiration), 80~89.3% (pharyngeal residues), and 60.7% (premature spillage) respectively. There was no evidence of statistical heterogeneity. The body of evidence as a whole suggests a grade C for FEES. CONCLUSION: FEES is considered as a safe and effective test in patients with dyspahgia and grade C evidence based on existing studies.

The Diagnostic Usefulness of the Fiberoptic Endoscopic Evaluation of Swallowing

OBJECTIVE: To investigate if adding fiberoptic endoscopic evaluation of swallowing (FEES) to the videofluoroscopic swallowing study (VFSS) will improve the detection of abnormalities related to swallowing and pharyngolaryngeal structures. METHOD: Sixty-nine subjects (47 men, aged 64.8+/-12.0 years) with dysphagia were evaluated using VFSS and FEES simultaneously. VFSS and FEES were independently interpreted by two different examiners, who were blinded to the results of the other study. The foods that were examined were a 5-ml semi-blended diet (SBD), plain yogurt, boiled rice (NRD), and 2-ml (small fluid, SF) and 5-ml (large fluid, LF) diluted liquid barium. The detection rates of penetration or aspiration and of the pharyngeal residues in VFSS and FEES were compared. RESULTS: Combining FEES with VFSS raised the detection rates of penetration (p=0.008 for SF and LF; p<0.001 for SBD, yogurt, and NRD) and of the pharyngeal residues (p<0.001 for SF, SBD, yogurt, and NRD; p=0.001 and 0.002 for LF in the vallecula and pyriform sinus, respectively) in all the food types. Adding FEES also improved the detection of fluid aspiration (p=0.03 and 0.02 for SF and LF, respectively). Oral and pharyngeal lesions such as candidiasis, and other mucosal abnormalities, were also detected by FEES. CONCLUSION: Combining FEES with VFSS raised the diagnostic sensitivities of penetration, aspiration, and pharyngeal residues compared to the evaluation using VFSS alone. It also enabled the visualization of the abnormal structural changes in the pharyngolarynx. FEES can be performed safely by physiatrists.

The Assessment of the Dysphagia Following Stroke / 医学研究杂志

Objective To reduce the rate of dysphagia and inhalation pneumonia by changing the food dense and evaluate the swallow function by videofluoroscopy(VF) and fiberoptic endoscopic examination of swallowing(FEES). Methods The videofluoroscopy and fiberoptic endoscopic examination of swallowing were used in 50 healthy volunteer and 35 dysphagia person. Results Aspiration was find in 14% volunteer and penetration was find in 36% volunteer. The positive rate of videofluoroscopy was higher than of fiberoptic endoscopic examination of swallowing in the two indicators. The delay of the thin barium passed the pharynx was the danger factor of aspiration. Videofluoroscopy was more sensitive in diagnosis of penetration. The time that watery barium and pudding barium flowed from pharynx to epiqlottis is longer in patients than that in volunteer. Conclusion The videofluoroscopy and fiberoptic endoscopic examination could be predicted to some extend by some clinical swallowing abnormalities, which could increase the accuracy of clinical evaluation . The viscosity changing can decrease the rate of dysphagia and inhalation pneumonia.
