Objective: This study aims to investigate the role of three-dimensional visualization technique in the diagnosis and treatment of progressive hilar cholangiocarcinoma.
Methods: From January 2014 to February 2017, a three-dimensional visualization model was set up in 23 patients with progressive hilar cholangiocarcinoma. The distributions and variations of the hepatic portal ducts were observed. The tumors were classified based on Bismuth classification. The simulation operation was performed and the operation plan was established.
Results: All 23 patients revealed a clear relationship between the intrahepatic and extrahepatic ducts, as well as the tumors and ducts. An individualized surgery program was established through the accurate calculation of liver volume and residual liver volume. Among these patients, 13 patients completed radical resection of hilar cholangiocarcinoma combined with massive hepatectomy. No bile leakage occurred and no operative death was found.
Conclusion: For patients with progressive hilar cholangiocarcinoma, the optimized three-dimensional visualization technique can accurately demonstrate the dilated biliary tract system, provide a new standard to determine the presence of tumor and peripheral vascular invasion, help in establishing a reasonable individualized operation plan, reduce the incidence of bile leakage and liver failure after the operation, and improve the success rate of operation.

Purpose: There is no established method for visualizing the three-dimensional (3D) structure of the aqueous humor outflow tract. This study attempted to visualize the 3D structures of porcine and human ocular tissues, particularly the aqueous humor outflow tract using a transparency reagent composed of 2, 2-thiodiethanol.

Unlabelled: In congenital heart surgery, redo-sternotomies are very common. In most cases, sternal re-entry is achieved without serious complications. However, sometimes elective institution of peripheral cardiopulmonary bypass is needed for safe sternotomy, albeit with a long cardio-pulmonary bypass time.

The ant genus are fascinating ants due to their distinctive morphology, ecology, and rarity. In this study, a comprehensive revision of in the Afrotropical region is presented, through a combination of morphological examination under the light microscope and three-dimensional (3D) cyber-taxonomy based on microtomography (micro-CT). Micro-CT based 3D surface models of all species were used for virtual morphological visualisation and examination.

Objective: To evaluate the application value of CT diagnostic technology based on the Shukun Imaging Post-Processing System for early screening and diagnosis of lung cancer.
Methods: A total of 35 patients diagnosed with lung cancer postoperatively and 53 patients with benign nodules were included in this retrospective study, all of whom were treated in the Department of Thoracic and Cardiovascular Surgery of the Second Affiliated Hospital of Fujian Medical University from January 2020 to December 2023. All patients underwent chest spiral CT examinations.

Objective: To investigate the clinical efficacy of three-dimensional (3D) visualization technology assisted percutaneous nephrolithotomy (PCNL) in the treatment of complex upper urinary tract calculi.
Methods: This study retrospectively analyzed clinical data from 127 patients with complex upper urinary tract stones admitted to Yongchuan Hospital, Chongqing Medical University from January 2020 to January 2023. According to the treatment methods, the patients were divided into an observation group (3D visualization technology assisted PCNL, n = 69) and a control group (conventional PCNL, n = 58).
