Abstract: Objective To investigate the application of CT three dimensional reconstruction in patients with hilar cholangiocarcinoma （HCCA） underwent hepatectomy. Methods 33 patients with HCCA were recruited in our hospital between January 2013 and January 2017,and CT three dimensional reconstruction was performed in 19 patients and conventional CT check-up was done in 14 before operation. Results The tumor R0 resection in patients receiving CT three dimensional reconstruction before operation was completed in 12 patients with HCCA （63.2%）,while it was done in 6 （42.9%） in the control group （P<0.05）;the intraoperative blood loss were （425.3±124.5） ml and （539.4±234.7） ml （P<0.05）;the operation time were （3.2±1.3） h and （4.1±2.5） h（P<0.05）;the postoperative hospital stay were（11.7±4.8） d and（13.9±5.4） d（<0.05）,and the postoperative complications were 10% and 12%（P>0.05）,respectively,in the two groups. Conclusion CT three-dimensional reconstruction before operation might be helpful in evaluation of tumor invasion and hepatic blood vessels involvement,and in rehearsing the hepatectomy.
