Department of Hepatobiliary Surgery,Zhujiang Hospital ,Southern Medical University,Guangzhou510282,China Corresponding author:FANG Chi-hua,E-mail: fangch_dr@126.com Objective To study the value of abdominal three-dimensional medical image visible system in diagnosis and treatment of hepatolithiasis. Methods 22 patients’ 64-slice spiral computer tomography (CT) scan data which admitted to Zhujiang Hospital from 2007 to 2009 were chosen. The data was imported into abdominal three-dimensional medical image visible system for sequence segmenting and three-dimensional (3D) reconstruction. According to the models, patients were diagnosed and the pre-operation plannings were made. The reconstructed models were used to perform simulation surgery with virtual surgical instruments simulation system. At last, clinical surgerys were guided by simulation surgery. Result within the 22 patients, 4 were type I, 2 were type Ⅱ, and 16 were type E. Including 6 patients with surgeries on biliary tract for several times; 16 cases with bile duct striture; 5 cases with cirrhosis; 16 cases with atrophy-mast syndrome. The 3D models showed the size, the amount and the location of the stone clearly, as well as the lacation, the degree and the lenth of the sticture. The clinical surgeries wre consistent with the simulation sugeries by 19/22(the other three wre emergency). T-tube angiography of the non-emergency patients showed that there were no stones residue. Conclusions The abdominal three-dimensional medical image visible system can make a rapid dignosis of hepatolithiasis, which was helpful for planning for the individual treatment.
