Objective: Paper for CT imaging in three-dimensional visualization technology for laparoscopy combined with biliary hard lens therapeutic clinical effect of extrahepatic bile duct stones were evaluated. Methods: Abdominal medical image 3D visualization software for our hospital CT imaging diagnosis and treatment of bile duct stones in 45 patients of bile duct stones three-dimensional visualization of clinical analysis and preoperative planning, and brought it into the operating room three-dimensional visualization model, guiding the implementation of the joint 3D laparoscopic biliary lithotripsy targeted hard lens. At the same time, as well as consistency with the actual hepatolithiasis distribution calculation operative 3D model visualization display; The operative time, bleeding, blood transfusion, stone clearance rate, morbidity and mortality perioperative after review stone recurrence rate was observed. Results: reproducing a three-dimensional patient model visualization liver, intrahepatic vascular anatomy of the liver bile duct stones distributed, real intraoperative and preoperative displayed three-dimensional visualization model consistent, pre-operative manner consistent with preoperative planning. Operation time (125.9±21.2) minutes, blood loss (38.8±8.5) ml, no massive hemorrhage and blood transfusion; MRCP examination by stone clearance rate was 100%; 2 biliary injury, bile leakage 1 complication the rate was 6.7%; There were no perioperative deaths. Stone recurrence two cases, the recurrence rate of 4.4%. Conclusion: The three-dimensional visualization techniques may be implemented hepatolithiasis accurate assessment of preoperative, intraoperative guidance of laparoscopic, endoscopic biliary hard gravel, stone liver resection operation, help to improve stone clearance rate, guarantee operation safety. |
