Abstract: Objective:To explore the value of threedimensional visualization technology in the resection of primary retroperitoneal liposarcoma(PRPLS).
Methods:The clinical data of a male patient aged 64 years with PRPLS who was admitted to the Chenggong Hospital in July 2014 were retrospectively analyzed. The preoperative abdominal images of computed tomography (CT) were converted to the threedimensional images by threedimensional visualization technology. The patient underwent a full preoperative assessment by observing the relationship of tumor and abdominal viscera as well as major abdominal vessels and measuring the volume of tumor and surgery simulation. The tumor was completely resected according to the preoperative surgical plan. During the operation, adhesion was separated along liposarcoma coating and the tumor was stripped out from the right kidney, inferior vena cava and liver. The patient was followed up by CT examination after surgery till September 2014.
Results:The threedimensional reconstruction of the CT data of the patient clearly displayed the anatomical structure and adjacent relationship between the tumor, abdominal organs and major abdominal vessels. The preoperative evaluation of the anatomy of the tumor based on threedimensional images was confirmed with operative findings. The operation time was 5.5 hours, the volume of intraoperative blood loss was 1 500 mL and the weight of resected tumor was 7.512 kg. The patient was discharged at postoperative week 2. No tumor recurrence was detected by CT examination at postoperative month 2.
Conclusion:The threedimensional visualization technology will be a feasible method to exactly evaluate and develop surgery plan and reduce the blindness of operation, meanwhile, it can provide significant clinical efficacy for patients.
