Objective To evaluate the resectability of hilar cholangiocarcinoma using three-dimensional visualization technique. Methods A retrospective analysis was done using the clinical data of 15 patients with hilar cholangiocarcinoma who underwent radical dissection between June 2018 and January 2019 in Department of General Surgery Zhongshan Hospital. Epigastric computed tomography scan combined with three-dimensional visualization by 3D-Liver imaging analysis system was performed for assessment of anatomical variants, tumor classification, vascular invasion, respectability and preoperational planning. We compared preoperative assessment with operative finding, and analyzed operative time, blood loss and peri-operative complication. Results Based on three-dimensional visualization of Bismuth-Corlette classification, there were 3 cases in type Ⅱ, 10 cases in type Ⅲ, and 2 cases in type Ⅳ. Liver volume was evaluated (1 286.06± 321.56) mL, and left and right liver volume were (451.90± 173.98) mL and (834.14± 220.34) mL, respectively. The tumor volume was evaluated as (15.19± 12.91) mL. Twelve in 15 patients (80%) completed radical resection, which was consistent with preoperative evaluation. There were 5 cases with variant hepatic artery, 4 cases with variant hepatic vein and 1 case with variant portal vein, which was all correctly evaluated preoperatively. Eleven patients had liver resection. Operative time was (343± 111) minutes with blood loss (355± 189) mL. Conclusions Three-dimensional visualization had important role in preoperative assessment of hilar cholangiocarcinoma and allowing operation safety.
