Abstract
：Objective To evaluatethe clinical effect of three-dimensional visualization technology in middle pancreatectomy(MP). Methods The original image data of 64-slices piral CT were obtained from 3 patientswith tumor in the neck or body of the pancreas. Data were impoted in the medical imageproceeding system (MIPS) which was designed by us. Then pancrea, pancreatic tumor,vascular system and other organs around the pancrease were three-dimensionallyreconstructed. By observing the spatial anatomical relationship between tumor andsurrounding organs or blood vessels, surgical approach was designed to guide operation.Results Using MIPS, the pancreas, tumos, surrounding organs and blood vessels in 3patients were three-dimensionally reconstructed successfully, and these 3D pictures couldclearly show the spatial anatomy of tumor and surrounding organs by visualizationtechniques. According to the results of three-dimensional reconstruction, two patientswere performed middle pancreatectomy successfully with open operation, and one patient wasperformed laparoscopic middle pancreatectomy successfully. No postoperative complicationssuch as bleeding, pancreatic leakage or diabetes were observed. ConclusionThree-dimensional reconstruction and visualization technology have great potential valuesfor designing individualized pancreatic surgery, and it can further expand to applicationfor other abdominal surgery.
