【摘要】：目的探讨数字三维重建技术在复杂食管异物诊断及治疗中的应用价值。方法收集18例复杂食管异物患者的CT扫描图像,导入腹部医学图像三维可视化系统,分割及三维重建患者食管异物三维模型,将重建后的三维模型导入可视化手术平台,进行手术预案的设计及手术预演,最后按照手术预案进行食管异物取出术,根据手术效果评价数字三维重建技术的应用价值。结果 18例患者重建后的食管异物模型形态逼真,立体感强,清晰地显示食管异物与周围重要器官、主动脉、腔静脉及门静脉的关系;术前按照手术预案反复演练,成功地指导临床进行食管异物取出手术。结论数字三维重建技术有助于复杂食管异物患者术前手术方案的设计;可视化复杂食管异物取出手术的预演有利于术者熟悉手术程序,减少手术失误,缩短手术时间。
[Abstract]:Objective to evaluate the value of digital three-dimensional reconstruction in the diagnosis and treatment of complex esophageal foreign bodies. Methods the CT scanning images of 18 patients with complicated esophageal foreign bodies were collected. The 3D visualization system of abdominal medical images was introduced. The 3D models of esophageal foreign bodies were segmented and reconstructed. The reconstructed 3D models were imported into the visual operation platform. The design of the operation plan and the operation preview were carried out. Finally, the foreign body of esophagus was removed according to the operation plan, and the application value of digital 3D reconstruction was evaluated according to the effect of the operation. Results the reconstructed esophageal foreign body model in 18 patients was lifelike and three-dimensional, showing clearly the relationship between esophageal foreign body and peripheral important organs, aorta, vena cava and portal vein. The procedure of removing foreign body of esophagus was successfully guided. Conclusion the digital 3D reconstruction technique is helpful to the design of preoperative operation plan for complicated esophageal foreign body patients, and visual preview of complex esophageal foreign body removal surgery is helpful for the operators to familiarize themselves with the procedure, to reduce the errors and to shorten the operation time.
