Abstract (2. Language): 
Currently, gastrointestinal tract malignancies have become important cause of morbidity and mortality. Preoperatif precise staging of these malignancies do have very important role to determine treatment protocols and prognosis. Effective preoperative staging of these malignancies could be achived by using such procedures like transabdominal US, CT, MRI, endoluminal US, intraoperative US. In these study, we aimed to evaluate preoperative effectivness of diagnostic procedures by retrospective study of our operated patients with gastrointestinal malignancy. The results of the tools used in preoperative staging ( specificity, sensitivity, positive predictive value, negative predictive value, diagnostic accuracy ) were evaluated with the guidance of literature knowledge in 45 female, 47 male, total 92 patients. Esophagus-stomach-duedonum x-ray graphics and endoscopy were found to be valuable diagnostic tools in gastric malignancies. The results of staging with CT and US were found to be in accordance with literature knowledge in T and M but not in N. We also observed, the importance of double contrast colon graphy and rectosigmoidoscopy as diagnostic tools in colorectal malignancies. The results of CT scans were found to be in accordance with literature where as US evaluation yielded low N detection and high M detection in comparison to CT. Diagnostic accuracy of the preoperative imaging can be increased with sophisticated devices, experienced users, and selection of the proper methods.

Abstract (Original Language): 
Günümüzde büyük morbidite ve mortaliteye sahip gastrointestinal sistem malignitelerinin tedavi ve prognozunu belirlemede preoperatif dönemde yapılan doğru bir evreleme kuşkusuz çok önemli bir rol oynamaktadır., Bu çalışmadaki amacımız hastanemizin kuruluş aşamasında gastrointestinal sistem malignilesi nedeniyle ameliyat edilmiş hastalarımızın retrospektif olarak preoperatif tanı yöntemlerinin (transabdominal ultrasonografi, bilgisayarlı tomografi, magnetik rezonans görüntüleme (MRG), endolüminal ultrasonografı ve intraoperatif ultrasonografı) değerlerini ortaya koymaktı. Preoperatif evrelemede kullanılan yöntemlerin sonuçları [spesifısite, sensitivite, pozitif prediktif değer(PPD), negatif prediktif değer (NPD) ve doğruluk oranları (DO)] literatür bilgileri ışığında 45 kadın, 47 erkek olmak üzere toplam 92 hastada değerlendirildi. Gastrik malignitelerde özofagus-mide-duedonum grafisi ve endoskopinin tanısal değeri bilinmektedir. Bilgisayarlı tomografi (BT) ve ultrasonografı (US) ile evre/emede bu yöntemlerin etkinliği, tümör (T) ve metastaz (M) açısından literatürle uyumlu, nodal tutulum (N) açısından düşük bulundu. Kolorektal malignitelerde de çift kontrast kolon grafisi ve rektosigmoidoskopi tanısal değer taşımaktadır. Bu grup malignitelerde BT sonuçlarımız literatürle uyumludur. US sonuçlarımızda N düşük bulunurken, M saptaması BT'ye göre daha üstündür. Preoperatif inceleme yöntemlerinin tanısal doğruluğu, gelişmiş cihazların kullanılması, kullanıcıların deneyimli olması ve uygun çalışma protokollerinin seçilmesiyle arttırılabilir.
