Value of 3D Printing for Comprehension of Liver Surgical Anatomy
In Brief
An observational study evaluating surgical residents' comprehension of the hepatic anatomy for Liver Cancer. Completed, enrolled 59 participants across 1 site.
Detailed Summary
To our knowledge, it has not been analyze whether 3D printed liver model would improve the perception of a given liver tumor or the precision of operation planning in liver surgery. We design this prospective controlled trial to test whether the 3D-printed patient specific liver model could be more informative than standard MDCT (multi-row detector computed tomography ) and 3D visualization system in predicting the surgical anatomy of liver.
Study Details
Timeline
Interventions
Surgical residents were assigned to three different groups to evaluate different modes of patients' data. Residents were ask to state the liver segment in which the tumor resided and make a minimal resection proposal, including the tumor, the safety margin (1cm) and the dependent liver tissue. Residents were recommended to proceed in a classic way by resecting the whole liver segment. The time spent by each resident was also recorded in order to assess the quickness of comprehension and information transfer of the three different modes of presentation.
