Amaç
Bu çalışmada, bilgisayarlı tomografi (BT) kolonografi yapılan hastalardaki kolon dışı bulguların sıklığı ve klinik öneminin araştırılması amaçlandı.
Gereç ve Yöntem
Toplamda 52 (24 kadın, 28 erkek) olgu çalışmaya dahil edildi. BT kolonografi optik kolonoskopiden 1-2 gün sonra gerçekleştirildi. Tetkikler, hasta öyküsü ve optik kolonoskopi verilerini bilmeyen bir radyolog tarafından raporlandı. Kolon dışı bulgular; BT kolonografi raporlama ve veri sistemine uygun olarak normal, minör, orta ve majör derecede önemli olarak sınıflandı.
Bulgular
Hastaların %75’i (39/52) en az bir ekstrakolonik bulguya sahipti. 19 hastada (%36,5) birden fazla kolon dışı bulgu gözlendi. Toplamda 75 kolon dışı bulgu saptandı. Bunlardan 59’u (59/75=%75) minör, 7’si (7/75= %9) orta ve 9’u (9/75= %12) majör derecede önemli kolon dışı bulgulardı. 11 kolorektal kanserli olgudan 4’ü orta, 7’si ağır kolon dışı bulguya sahipti. Ağır kolon dışı bulgular kolorektal kanser olgularında görüldü.
Sonuç
Orta ve yüksek önem dereceli kolon dışı bulguların hastanın yaşam beklentisi üzerine etkisi olduğundan, intravenöz kontrast madde kullanılarak yapılan BT kolonografilerde kolon dışı bulguların da değerlendirilmesi çok önemlidir.
Extracolonic Findings on CT Colonography
AimThe purpose of this study was to assess the incidence and clinical significance of extracolonic findings in the screening population undergoing computed tomography (CT) colonography.Material and MethodsA total of 52 patients (24 females, 28 males) have been included in this study. CT colonography has been performed 1 or 2 days after optic colonoscopy. Patient history and the results of optic colonoscopy have never been informed to the radiologist. Extracolonic findings were classified asnormal, minor, moderate and major by CT colonography reporting and data system.ResultsA total of 75 extracolonic findings have been recorded and 75% of patients (39/52) had at least one extracolonic finding. Nineteen patients (36.5%) had more than one extracolonic findings. In total, 59 (59/75= 79%) minor, 7 (7/75= 9%) moderate and 9 (9/75= 12%) major extracolonic findings were found. Four of 11 colorectal cancer patients had moderate findings and 7 of colorectal cancer patients had major findings. Extracolonic significant findings were mostly seen in patients with colorectal cancer.ConclusionThe evaluation of extracolonic findings on CT colonography with using intravenous contrast material in colorectal cancer patients is critical because important extracolonic findings of this patient can be effect his/her survey.<span style="font-size: 18px;"><br />
