Perfore Apandisit: Ultrasonografik Bir Tanısal Zorluk

Year 2018, Volume: 51 Issue: 2, 110 - 115, 29.08.2018

Abstract

Abstract:



Aim: Perforated
appendicitis (PA) cases are more common amongst pediatric population. Imaging
plays an important role in PA diagnosis; clinical distinction can be quietly
difficult, especially in younger children. Unfortunately, PA is defined as a
potential pitfall in US evaluation, because a perforated appendix usually
decompresses and becomes difficult to identify. In the current study, we mainly
aim to define diagnostic US characteristics of PA, and determine most specific
and sensitive US findings



Materials
and methods: We retrospectively evaluated the medical records and US reports of
the children who were referred to the radiology department with a clinical
diagnosis of acute appendicitis. We have recorded sedimentation (ESR), C
reactive protein (CRP), and leukocyte count. We have recorded presence of
loculated fluid in periappendiceal area, appendicolith, presence of complex
fluid, increase in echogenicity of periappendiceal fat, fluid collection in
abdominal recesses, increase in periportal liver echogenicity.



Results: Study
population consists of 132 patients.  Loculated
fluid collection in periappendiceal area, presence of appendicolith, fluid
collection in 3-4 areas, and in all five areas, ESR, and CRP values are found
to be effective for the differentiation. 
We define the combination of loculated fluid collection, presence of
ascites in all five areas, and elevation of CRP levels as the most successful
combination for detecting PA (98.2% specificity, 48.3% sensitivity).



Conclusion:
Detection of loculated fluid in periappendiceal area, and fluid collection in
all abdominal recesses is the most valuable US parameters.  Combination of these parameters with CRP
levels can increase diagnostic performance.

Özet:



Amaç:
Perfore apandisit (PA) vakaları pediyatrik popülasyonda, özellikle 5 yaş altı
çocuklarda daha sık görülmektedir. Perfore apandisit vakalarında klinik pek çok
başka patoloji ile örtüşebildiğinden görüntüleme yöntemleri tanıda önem kazanmaktadır.
Ne yazık ki, perforasyon sonucu apendiks dekomprese olduğundan, ultrason
incelemesi ile perfore apandisiti tanımlamak güç olabilmektedir. Güncel
çalışmada, perfore apandisit tanısı için en yararlı sonografik parametrelerin belirlenmesi
hedeflenmiştir.



Gereç ve yöntem: Radyoloji bölümüne akut apandisit ön tanısı
ile yönlendirilen çocukların medikal kayıtları geriye dönük olarak taranmıştır.
Eritrosit sedimentasyon hızı (ESH), C reaktif protein (CRP) düzeyleri, lökosit
sayımları kaydedilmiştir. Ayrıca sonografik paramatreler olarak; apendiks
çevresinde lokule sıvı varlığı, apendikolit tespiti, kompleks serbest sıvı
bulunması, periapendisyel yağ dokuda ekojenite artışı olması, abdominal
reseslerde asit tespit edilmesi ve periportal ekojenite artışı olması
belirlenmiştir.



Bulgular:
Araştırma popülasyonu 132 hastadan oluşmaktadır. Apendiks çevresinde lokule
koleksiyon tespit edilmesi, apendikolit varlığı, 3-4 abdominal reseste sıvı
bulunması, tüm abdominal reseslerde sıvı bulunması, ESH, CRP değerlerinde artış
olması parametreleri PA varlığını başarı ile öngörmektedir. Ayrıca, apendiks
çevresinde lokule koleksiyon tespit edilmesi, tüm abdominal reseslerde sıvı
bulunması ve CRP değerlerinde artış olması paramaterelerinin kombinasyonu
(%98.2 spesifik, %48.3 sensitf),  PA
tanısında oldukça yararlı bulunmuştur.



Sonuç:  Apendiks çevresinde lokule koleksiyon tespit
edilmesi ve tüm abdominal reseslerde sıvı bulunması en değerli sonografik
parametrelerdir. Bu parametrelere CRP değerinin de eklenmesi tanısal başarıyı
arttırabilir.
