Abstract:
Objective To correlate between the IQQA(R)-Liver system in planning liver resection and the actual operation performed by surgeons.Methods The data on 65 patients were retrospectively studied.Their preoperative enhanced CT images were analyzed by the IQQA(R)-Liver system to determine the operative plan (Group Q) including the operative technique,the major vessels which required to be transected and the virtual liver resection volume.The above results and the corresponding data collected from the actual operation (Group S) were statistically analyzed to find out whether there was any correlation between them,thus determining the clinical significance of the IQQA(R)-Liver system in preoperative evaluation.Results Group Q and Group S had good correlation in the operative techniques (O) and in the major vessels that required to be transected (A) (uO =0.835,uA =0.893) with no statistical difference between the 2 groups (PO =0.494,PA =0.331).The virtual liver resection volume was 633.96 ± 512.06 (78.30 ～2 559.38)cm3.Conclusion Preoperative evaluation by the IQQA(R)-Liver system had significance in planning partial hepatectomy.
