Abstract
Background
A preoperative surgical strategy before hepatectomy for hepatocellular carcinoma is
fundamental to minimize postoperative morbidity and mortality and to reach the best
oncologic outcomes. Preoperative 3D reconstruction models may help to better choose
the type of procedure to perform and possibly change the initially established plan
based on conventional 2D imaging.
Methods
A non-randomized multicenter prospective trial with 136 patients presenting with a
resectable hepatocellular carcinoma who underwent open or minimally invasive liver
resection. Measurement was based on the modification rate analysis between conventional
2D imaging (named “Plan A”) and 3D model analysis (“Plan B”), and from Plan B to the
final procedure performed (named “Plan C”).
Results
The modification rate from Plan B to Plan C (18%) was less frequent than the modification
from Plan A to Plan B (35%) (OR = 0.32 [0.15; 0.64]). Concerning secondary objectives,
resection margins were underestimated in Plan B as compared to Plan C (−3.10 mm [−5.04; −1.15]).
Conclusion
Preoperative 3D imaging is associated with a better prediction of the performed surgical
procedure for liver resections in HCC, as compared to classical 2D imaging.
