The Eating Assessment Tool-10 (EAT-10) is widely used to screen for dysphagia symptoms, particularly in patients with scores ≥ 3. However, the underlying pathophysiological mechanisms and specific swallowing muscle impairments associated with dysphagia symptoms after ACDF remain incompletely understood. Videofluoroscopy is considered the gold standard for evaluating swallowing function. High-resolution impedance manometry (HRIM) enables quantitative assessment of pressure dynamics during swallowing. Therefore, this study aimed to identify alterations in pharyngeal contractile function and pathophysiological changes associated with dysphagia symptoms following ACDF using HRIM and videofluoroscopy.</p><p><strong>Methods: </strong>Patients who underwent ACDF within one year postoperatively were enrolled in this cross-sectional study. Dysphagia symptoms were defined as an EAT-10 score ≥ 3. Swallowing function was evaluated using HRIM and videofluoroscopy. Swallowing tests were performed with two food textures, as defined by the International Dysphagia Diet Standardisation Initiative (IDDSI): level 0 (thin liquid) and level 4 (extremely thick liquid). HRIM parameters were compared between patients with and without dysphagia. Aspiration was defined as a Penetration-Aspiration Scale (PAS) score ≥ 6 on videofluoroscopic examination.</p><p><strong>Results: </strong>A total of 43 patients were included, comprising 29 with dysphagia symptoms and 14 without. During thin liquid swallowing (IDDSI level 0), patients with dysphagia symptoms had significantly lower hypopharyngeal mean peak pressure (hypoPeakP) and higher Swallow Risk Index (SRI) compared with those without dysphagia symptoms (median 55.79 vs. 104.85 mmHg and 18.60 vs. 4.30, respectively). During extremely thick liquid swallowing (IDDSI level 4), hypoPeakP remained significantly lower in the dysphagia symptoms group (median 86.96 vs. 161.19 mmHg), whereas SRI did not differ significantly between groups. No aspiration events were observed.</p><p><strong>Conclusions: </strong>Post-ACDF dysphagia symptoms were associated with reduced hypopharyngeal contractile pressure.

However, EF was validated primarily in chronic cardiovascular disease and long-term heart failure management, raising important questions about its suitability as a dominant marker of short-term perioperative risk. EF does not capture key determinants of perioperative vulnerability, including diastolic function, ventricular compliance, right ventricular function, venous congestion, or contractile reserve. Contemporary clinical data suggest that only severely reduced EF (< 30%) is consistently associated with markedly increased perioperative risk, whereas mildly to moderately reduced EF in clinically stable patients often carries less prognostic significance than preserved EF in the presence of heart failure with preserved ejection fraction (HFpEF), congestion, or right ventricular dysfunction. Common perioperative scenarios such as HFpEF, distributive shock, hypovolemia, venous congestion, and chronic compensated heart failure illustrate that EF may substantially underestimate or overestimate true hemodynamic vulnerability depending on the physiological context. In contrast, functional capacity, volume status, and clinical stability emerge as more robust determinants of short-term perioperative risk. Advanced echocardiographic parameters, including diastolic indices, global longitudinal strain (GLS), and focused assessment of right ventricular function, together with biomarkers provide a more physiologically coherent risk profile. The uncritical use of EF as a primary perioperative risk marker is not supported by current evidence. For anesthesiologists, EF should be interpreted as one component within a multidimensional, physiology-guided assessment that integrates focused perioperative ultrasound, clinical history, and targeted biomarkers to more accurately characterize perioperative cardiovascular risk.</p>","PeriodicalId":19764,"journal":{"name":"Perioperative Medicine","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147841070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
