Abstract:
Objective To investigate the accuracy and availability of three‐dimensional ultrasonography ( 3DUS ) in the Bismuth‐Corlette classification of hilar cholangiocarcinoma ( HCCA ) . Methods Forty‐eight patients who underwent surgery and obtained pathologic diagnosis of HCCA were retrospectively analyzed . All patients underwent 3DUS and magnetic resonance cholangiopancreatography (MRCP) before surgery . With surgical outcomes as the gold standard ,the diagnostic efficacy of two examinations in classification of HCCA were compared . Results Forty‐eight cases of HCCA were divided into 5 types according to surgical results ,including type Ⅰ (8 cases) ,type Ⅱ(13 cases) ,Ⅲa(8 cases) ,Ⅲb (11 cases) and type Ⅳ(8 cases) respectively . Among them ,39 cases accepted radical resection and the rest of 9 cases received palliative resection . The accuracy of the Bismuth classification confirmed by 3DUS was 85 .4% (41/48) . The percentage of underestimated and overestimated classification confirmed by 3DUS were 10 .4% (5/48) and 4 .2% (2/48) respectively . The accuracy of the classification confirmed by MRCP was 87 .4% (42/48) .Both of the percentage of underestimated and overestimated classification confirmed by MRCP were samely 6 .3% (3/48) .The difference between the 3DUS and MRCP was not statistically significant(χ2 =0 .597 ,P=0 .440) . Both the percentage of underestimated and overestimated classification between 3DUS and MRCP were samely not statistically significant ( P =0 .714 , P =1 .000 ,respectively) . Conclusions As a new diagnostic technique ,3DUS was feasible and had significant value in evaluating HCCA classification comparable to MRCP .
