Preoperative Evaluation of Resectability of Klatskin Tumor with 16-MDCT Angiography and Cholangiography

Abstract

Preoperative MDCT angiography and cholangiography gave a good assessment of the degree of vascular and biliary involvement of the Klatskin tumor.

Biliary tract carcinoma – determination of therapeutic possibilities in the imaging evaluation of tumor progression

“…Wartość diagnostyczna wielorzędowej tomografii komputerowej (WRTK) jest znacznie wyższa. Dokładność w uwidocznieniu masy guza wynosi prawie 100%, natomiast w ocenie resekcyjności 74,5-91,7% [8,14].…”

“…Podejrzenie guza wysuwa się zwykle na podstawie objawów pośrednich cholestazy. W takich przypadkach zalecanymi badaniami są tomografia komputerowa z uży-ciem kontrastu, endoskopowa cholangiopankreatografia wsteczna (ECPW), rezonans magnetyczny oraz cho langiopankreatografia rezonansu magnetycznego (ma gnetic resonance cholangiopancreatography -MRCP) [1,5,6,13,14]. Endoskopowa cholangiopankreatografia wsteczna umożliwia określenie miejsca i stopnia przewężenia przewodu żółciowego.…”

Correct Diagnosis of Vascular Encasement and Longitudinal Extension of Hilar Cholangiocarcinoma by Four-Channel Multidetector-Row Computed Tomography

“…Recent reports of MDCT cholangiography (Lee et al 2006;Chen et al 2006) documented accuracies of 100% (18/18) and 91% (10/11). This approach may be promising, although it has the same shortcomings, as mentioned for direct cholangiography.…”

“…Although there have been several studies on the preoperative assessment of resectability of hilar cholangiocarcinoma by multidetector-row computed tomography (MDCT) (Lee et al 2006;Chen et al 2006), these studies used relatively thick section images (2.5 mm) with no multiplanar reformation or overlap reconstruction for evaluating the biliary tree.…”

Trends in the surgical management of Klatskin tumours

“…Recently, multidetector computed tomographic angiography and cholangiography with threedimensional reconstruction have been described, with encouraging results 3 . However, staging modalities have limitations and preoperative evaluation of the precise extent of biliary and vascular involvement remains a major challenge.…”
