Abstract: Pancreatic cancer is a relatively common malignant tumor in hepatobiliary and pancreatic surgery, with insidious onset, atypical early symptoms, easy to metastasize, and a five-year survival rate of less than 6%. Pancreaticoduodenectomy is the standard procedure for pancreatic and peripelvic tumors, and laparoscopic pancreaticoduodenectomy has higher requirements for the operator's luminal technique, and more precise requirements for the assessment of tumor invasion of adjacent organs and vascular variations. Three-dimensional visualization technology integrates digital medicine, computer and artificial intelligence technologies, and the three-dimensional visualization platform can reorganize and integrate two-dimensional image data to construct three-dimensional abdominal anatomical structure images, and the three-dimensional display of the anatomical structure around the pancreas is conducive to improving the accuracy of preoperative assessment, increasing the safety of the operation, accelerating the patient's recovery after the operation, and achieving the purpose of precise treatment, which is in line with the accelerated recovery surgery concept. The concept is in line with the accelerated rehabilitation surgery.

摘要： 胰腺癌是肝胆胰外科较为常见的恶性肿瘤,其起病隐匿,早期症状不典型,易发生转移,五年生存率低于6%。胰十二指肠切除术（PD）是胰腺及壶腹周围肿瘤的标准术式,而腹腔镜胰十二指肠切除术（LPD）对术者腔镜技术要求更高,对肿瘤的邻近器官侵犯及血管变异的评估具有更精准的要求。三维可视化技术将数字医学、计算机和人工智能技术相互融合,利用三维可视化平台可将二维影像数据进行重组整合,构建立体腹腔解剖结构图像,对胰腺周围解剖结构的立体化展示有利于提高术前评估的准确性,增加手术安全性,加速患者术后康复,达到精准治疗的目的,符合加速康复外科（ERAS）理念。
