KOLOREKTAL POLİP VE KANSERLERİN SAPTANMASINDA BİLGİSAYARLI TOMOGRAFİK KOLONOGRAFİ İLE VİDEO KOLONOSKOPİNİN KARŞILAŞTIRILMASI

Abstract

Amaç: Çok kesitli bilgisayarlı tomografi kolonografinin kolorektal patolojileri saptamadaki tanısal duyarlılığını video kolonoskopi ile karşılaştırarak belirlemektir.

Gereç ve Yöntemler: Çalışmamızda 18 aylık period içerisinde çok kesitli bilgisayarlı tomografi kolonografi ve video kolonoskopi yapılan 70 hasta retrospektif olarak incelendi ve çok kesitli bilgisayarlı tomografi kolonografi bulguları video kolonoskopi bulguları ile karşılaştırıldı.

Bulgular: Hastaların %57.1’i erkek (n=40) ve %42.9’u kadın (n=30) olup ortalama yaşları 52.8 /yıl idi. Video kolonoskopi ile toplam 39 polip, 15 kolon tümörü, 5 ülseratif kolit, 4 divertikülozis koli, 1 anjiodisplazi ve 1 nonspesifik proktosigmoidit olmak üzere 38 hastada 65 patoloji saptandı. Saptanan 39 polipten 31’i ≤5 mm, 4’ü 6-9 mm ve 4’ü ≥10 mm idi. Çok kesitli bilgisayarlı tomografi kolonografinin boyut farkı gözetmeksizin tüm poliplerde duyarlılığı %64.1, ≥10 mm poliplerde %100, 6-9 mm arası poliplerde %75, ≤5 mm poliplerde %58.1 idi. Duyarlılık kolon tümörlerinde %100, divertikülozisde %75 ve ülseratif kolitte %80 bulundu.

Sonuç: Çok kesitli bilgisayarlı tomografi kolonografinin kolon patolojilerinin tanısında yüksek duyarlılık ve özgüllüğe sahip olması, tarama yöntemi olarak veya kolon patolojilerinin değerlendirilmesinde, video kolonoskopiye ciddi alternatif ve tamamlayıcı bir yöntem olacağını göstermektedir.

Comparison of Computed Tomographic Colonography and Video Colonoscopy in the Detection of Colorectal Polyps and Cancers

Abstract

Objective: To determine the diagnostic efficiency of multislice computed tomography colonography in detection of colorectal pathologies compared with video colonoscopy.

Material and Methods: In our study, 70 patients who underwent multislice computed tomography colonography and video colonoscopy within an 18-month period were analyzed retrospectively, and multislice computed tomography colonography findings were compared with video colonoscopy findings.

Results: Of the patients, 57.1% were male (n=40) and 42.9% were female (n=30), with a mean age of 52.8 years. A total of 65 pathologies including 39 polyps, 15 colon tumors, 5 ulcerative colitis, 1 angiodysplasia and 1 nonspecific proctosigmoiditis, were detected in 38 patients by video colonoscopy. Of the 39 polyps detected, 31 were ≤5 mm, 4 were 6-9 mm and 4 were ≥10 mm. The sensitivity of multislice computed tomography colonography for detection of all polyps regardless their size was 64.1%, 100% for polyps ≥10 mm, 75% for polyps that are between 6-9 mm and 58.1% for polyps ≤5 mm. The sensitivity was 100% for colon cancers, 75% for diverticulosis and 80% for ulcerative colitis.

Conclusion: The high sensitivity and specificity of multislice computed tomography colonography in the diagnosis of colon pathologies will make it the screening modality and a serious alternative and complementary method for video colonoscopy in the evaluation of colon pathologies.
