Egzersizle Uyarılan Laringeal Obstrüksiyon (EULO) Olgusuna Akılcı Yaklaşım

ÖzEgzersizle uyarılan laringeal obstrüksiyon, istirahatte belirgin bir patoloji olma-dan, egzersiz sırasında laringeal hava yolunun uygun olmayan şekilde kapanmasını, öksürük, stridor ve nefes darlığı gibi semptomlara neden olmasını tanımlamaktadır. Laringeal obstrüksiyon supraglottik ve/ veya glottik düzeyde olabilir. Semptomlar sıklıkla inspiryumda, nadiren de ekspiryum da görülür. Egzersizle uyarılanlar ingeal obstriksiyon genç atletlerde yüksek prevelansa sahiptir ve tüm adölesanların %5-10’unu etkilediği tahmin edilmektedir. Araştırmalar EULO ile astımın birlikte bulunabileceğini göstermiştir ve bu iki durumun ayrımı zor olmaktadır. Semp-tom varlığında larinksin değerlendirilmesi anatomik tanı için tek objektif yoldur. Spirometri ve diğer testlerin sensitivite ve spesifitesi düşüktür; ancak yararlı klinik ipuçları sağlayabilir.

Logical Approach to the Patient witth Exercise - Induced Laryngal Obstruction (EILO)

AbstractExercise-induced laryngeal obstruction (EILO) describes a condition in which thelarynx closes inappropriately during vigorous exercise to precipitate respiratory symptoms, such as cough, stridor and breathlessness.1 EILO stridor symptoms typically peak towards the close of an exercise session and throughout the ﬁrst 2–3 minof recovery. Symptoms are most often limited to the inspiratory phase; rarely to the expiratory phase. The condition is highly prevalent in young athletes and estimatedto affect between 5% and 10% of all adolescents. Research has shown that EILO maycoexist with asthma, and distinguishing between these conditions can be challeng ingand often requires specialist investigation. Visualisation of the larynx during ongoing symptoms is the only objective way of making a complete anatomical diagnosis. Spirometry and other surrogate tests have poor sensitivity and specificity, but might provide useful clinical clues.
