Abstract:
Objective To study the medical image three dimensional visualization system(MI-3DVS)in the diagnosis and treatment of hepatolithiasis.Methods The data of 64-slice spiral computed tomography of 54 patients with hepatolithiasis who were admitted to the Zhujiang Hospital of the Southern Medical University from August 2008 to August 2010 were collected.The liver and bile duct were three dimensionally(3D)constructed.Preoperative diagnosis and pathological classification were made according to the results of the 3D model of liver and bile duct.The optimal surgical procedure was determined by simulating operations based on the 3D model.The compliance of simulated operation and actual operation was observed,and residual stones were detected by cholangiography.Results Of the 54 patients,11 were with type Ⅰ,5 with type Ⅱ(including 2 patients with type Ⅱ a and 3 with Ⅱ b),38 with type E.There were 23 patients with intrahepatic bile duct stricture and 27 with atrophy-hypertrophy syndrome complex.The anatomy of intra-and extrahepatic bile duct,dilation and stricture of the bile duct,site,size and number of the bile duct stones were clearly displayed in the MI-3DVS.The compliance rate of simulated surgery and actual surgery was 94%(51/54).There was no residual stones in 51 patients who received elective surgery and the rate of residual stone of the 54 patients was 6%(3/54).Conclusion Acurate preoperative diagnosis and intraoperative precise operation can be achieved and the rate of residual stone can be reduced by using the MI-3DVS.
