Background and Purpose: Dysphagia is an important complication of acute stroke with a reported incidence of up to 76%. The purpose of this investigation was to develop and to evaluate an endoscopic scoring system which has the potential to guide dysphagia management in acute stroke patients. Methods: A fiberoptic endoscopic evaluation of swallowing (FEES) was carried out in 100 patients within 72 h of stroke onset. During endoscopic examination, the secretion status was evaluated, and the patient was successively given standard volumes of puree consistency, liquids and soft solid food. Penetration and aspiration was assessed using a 5-point scale. Results: Nearly 80% of patients showed penetration or aspiration during FEES. These events occurred more frequently with liquids and soft solid food than with puree. Penetration or aspiration at any stage of examination predicted failure at the subsequent food consistency. Furthermore, key findings of endoscopic evaluation were predictive of the need for later orotracheal intubation. Based on these observations a score was developed that grades stroke-related dysphagia according to the risk of penetration or aspiration of the different food consistencies tested. Assessment of interrater reliability by means of 25 additional endoscopic examinations resulted in excellent agreement between three investigators, reflected by a ĸ coefficient of 0.89. Conclusion: Stroke-related dysphagia may effectively be graded using a simple endoscopic scoring system. The usefulness of this screening protocol with respect to patient outcome and intercurrent complications has to be studied in prospective clinical trials.

Background: Aspiration is a common complication in acute stroke patients and is strongly associated with a poor outcome. Due to an insufficient sensitivity and specificity of clinical bedside tests, further refinements are needed to improve the accuracy of clinical aspiration screening in acute stroke. Objective: To assess the ability of the simple 2-step swallowing provocation test (SPT) to detect aspiration risk in acute stroke patients. Methods: 100 consecutive patients with first-ever stroke were examined by SPT and fiberoptic endoscopic evaluation of swallowing (FEES) within 72 hours of stroke onset. Using FEES as an objective instrumental technique to evaluate dysphagia, statistical measures representing the ability of SPT to detect aspiration risk were calculated. Results: The incidence of endoscopically proven aspiration risk was 81%. The 1 st -step SPT had a sensitivity of 74.1% and a specificity of 100%. Although the 2 nd -step SPT showed the same 100% specificity, sensitivity was significantly lower. False-negative results of SPT appeared predominantly in subjects exhibiting leakage of liquids to pyriform sinus without a pronounced delay in swallow onset. Conclusions: In acute stroke patients with an impairment of the pharyngeal phase of swallowing, 1 st
