Abstract:
Objective:To study the value of three-dimensional(3D) visualization in the diagnosis and surgical treatment for pancreatic tumor.
Methods:From June to September 2016, 26 patients with pancreatic tumors in Jinling Hospital, Medical School of Nanjing University were involved. The study included 26 patients(8 females and 18 males) with mean age of (57±12)years (ranging from 23 to 77 years). And there were 20 malignant tumors and 6 benign tumors. All of them were examined with abdominal thin slice CT scanning and the CT images were imported into 3D visualization system for 3D visualization. The main elements examined by 3D visualization included tumor shape, size, and location; distribution and morphology of the peripancreatic lymph node; the relationships among neoplasms, organs and blood vessels.
Results:Among the 26 patients, there were 21 cases with pancreatic cancer, of which 15 cases successfully underwent standard pancreatectomy. All patients were operated underwent accurate assessment. The 3D model demonstrated the origination and bifurcations of blood vessels, and the relationships among neoplasms, organs and blood vessels efficiently. The 3D technique could facilitate to evaluate response of neiadjuvant chemotherapy in the pancreatic cancer patients (n=5).3D reconstruction could detect the lymph-node metastases accurately (n=12) in patients with pancreatic cancer. 3D reconstruction were applied to evaluate the the size and range of tumor on 5 cases.
Conclusions:3D reconstruction allows stereoscopic identification of the spatial relationships between physiologic and pathologic structures.The 3D technique could facilitate to evaluate distribution and morphology of the peripancreatic lymph node, and to evaluate the relationships among neoplasms, organs and blood vessels.
