Abstract

This study was conducted to evaluate the vascularity of benign and malignant gallbladder lesions and the mural flow associated with these lesions. The aim was to study the significance of hemodynamic parameters in the differential diagnosis of gallbladder lesions. Eleven patients with malignant lesions and 22 patients with benign lesions were examined with color Doppler ultrasound (US). Seven of 11 cases with malignancy were found to have blood flow signals in the tumor masses. No blood flow signal was observed in the benign masses of 15 cases. There was a significant difference between the flow detection rates in the tumor masses (p<0.001). Arterial blood flow signal within the gallbladder walls (mural flow) was observed in eight of the 11 (72%) malignancies and ten of 22 ( 45%) benign lesions. No significant difference was found between the detection rates of the mural flow (p>0.05). However, the mean values of both maximum and minimum flow velocities of mural flow were significantly higher in cases of malignant lesions (p<0.01). The blood flow signal observed within the mass and high velocity mural flow were suggestive signs of malignant gallbladder lesions. It is concluded that conclude application of color Doppler US can increase the diagnostic accuracy of gray-scale US in gallbladder carcinoma.

Özet

Bu çalışmada, safra kesesinin malign ve benign lezyonlarını ve kese duvarının damarlanma özelliklerini renkli Doppler ultrasonografi (RDUS) ile değerlendirdik. Ayrıcı tanı için anlamlı olabilecek hemodinamik parametreleri belirlemeyi amaçladık. Onbiri malign, 22'si benign olan 33 olgu RDUS ile incelendi. Malign kitlesi olan 11 olgudan 7'sinde kitle içinden akım alınırken, benign nitelikli 15 kitlenin hiçbirinde akım örneği alınamadı. Kitle içinde arteriyel akım saptanan lezyonların dağılımı bakımından benign ve malign lezyonlu gruplar arasındaki fark anlamlı idi (p 0.05). Bununla beraber, malign lezyonlarda duvardan alınan maksimum ve minimum akım hızlarının ortalama değeri, benign lezyonlarınkine kıyasla istatistiksel olarak anlamlı düzeyde yüksekti (p<0.01). Kitle içinden akım alınması ve kese duvarında yüksek hızlı kan akım örnekleri saptanması, primer safra kesesi kanseri lehinedir ve benign lezyonlar için olası bir bulgu değildir. Bu yönden RDUS'nin safra kesesi kanserlerinde gri-skala US'nin tanısal doğruluğunu arttıracak bir araç olduğunu düşünüyoruz.
