                            <p>Abstract:Aim: Perforatedappendicitis (PA) cases are more common amongst pediatric population. Imagingplays an important role in PA diagnosis; clinical distinction can be quietlydifficult, especially in younger children. Unfortunately, PA is defined as apotential pitfall in US evaluation, because a perforated appendix usuallydecompresses and becomes difficult to identify. In the current study, we mainlyaim to define diagnostic US characteristics of PA, and determine most specificand sensitive US findingsMaterialsand methods: We retrospectively evaluated the medical records and US reports ofthe children who were referred to the radiology department with a clinicaldiagnosis of acute appendicitis. We have recorded sedimentation (ESR), Creactive protein (CRP), and leukocyte count. We have recorded presence ofloculated fluid in periappendiceal area, appendicolith, presence of complexfluid, increase in echogenicity of periappendiceal fat, fluid collection inabdominal recesses, increase in periportal liver echogenicity. Results: Studypopulation consists of 132 patients. Loculatedfluid collection in periappendiceal area, presence of appendicolith, fluidcollection in 3-4 areas, and in all five areas, ESR, and CRP values are foundto be effective for the differentiation.We define the combination of loculated fluid collection, presence ofascites in all five areas, and elevation of CRP levels as the most successfulcombination for detecting PA (98.2% specificity, 48.3% sensitivity). Conclusion:Detection of loculated fluid in periappendiceal area, and fluid collection inall abdominal recesses is the most valuable US parameters. Combination of these parameters with CRPlevels can increase diagnostic performance.Keywords:US, perforated appendicitis, diagnosisÖzet: Amaç:Perfore apandisit (PA) vakaları pediyatrik popülasyonda, özellikle 5 yaş altıçocuklarda daha sık görülmektedir. Perfore apandisit vakalarında klinik pek çokbaşka patoloji ile örtüşebildiğinden görüntüleme yöntemleri tanıda önem kazanmaktadır.Ne yazık ki, perforasyon sonucu apendiks dekomprese olduğundan, ultrasonincelemesi ile perfore apandisiti tanımlamak güç olabilmektedir. Güncelçalışmada, perfore apandisit tanısı için en yararlı sonografik parametrelerin belirlenmesihedeflenmiştir. Gereç ve yöntem: Radyoloji bölümüne akut apandisit ön tanısıile yönlendirilen çocukların medikal kayıtları geriye dönük olarak taranmıştır.Eritrosit sedimentasyon hızı (ESH), C reaktif protein (CRP) düzeyleri, lökositsayımları kaydedilmiştir. Ayrıca sonografik paramatreler olarak; apendiksçevresinde lokule sıvı varlığı, apendikolit tespiti, kompleks serbest sıvıbulunması, periapendisyel yağ dokuda ekojenite artışı olması, abdominalreseslerde asit tespit edilmesi ve periportal ekojenite artışı olmasıbelirlenmiştir.Bulgular:Araştırma popülasyonu 132 hastadan oluşmaktadır. Apendiks çevresinde lokulekoleksiyon tespit edilmesi, apendikolit varlığı, 3-4 abdominal reseste sıvıbulunması, tüm abdominal reseslerde sıvı bulunması, ESH, CRP değerlerinde artışolması parametreleri PA varlığını başarı ile öngörmektedir. Ayrıca, apendiksçevresinde lokule koleksiyon tespit edilmesi, tüm abdominal reseslerde sıvıbulunması ve CRP değerlerinde artış olması paramaterelerinin kombinasyonu(%98.2 spesifik, %48.3 sensitf), PAtanısında oldukça yararlı bulunmuştur. Sonuç: Apendiks çevresinde lokule koleksiyon tespitedilmesi ve tüm abdominal reseslerde sıvı bulunması en değerli sonografikparametrelerdir. Bu parametrelere CRP değerinin de eklenmesi tanısal başarıyıarttırabilir.
