Journal ArticleDOI
Comparison of video trainer and virtual reality training systems on acquisition of laparoscopic skills.
Elizabeth Costa Hamilton,Daniel J. Scott,Jason B. Fleming,Robert V. Rege,Royce Laycock,Patricia C. Bergen,S. T. Tesfay,Daniel B. Jones +7 more
TL;DR: Psychomotor skillsimprove after training on both VR and VT, and skills may be transferable, and training on a minimally invasive surgery trainer, virtual reality system may improve operative performance during laparoscopic cholecystectomy.
Journal ArticleDOI
Measuring operative performance after laparoscopic skills training: edited videotape versus direct observation.
Daniel J. Scott,Robert V. Rege,Patricia C. Bergen,W. A. Guo,Royce Laycock,S. T. Tesfay,R. J. Valentine,Daniel B. Jones +7 more
TL;DR: Direct observation demonstrated improved overall performance of junior residents after formal skills training on a videotrainer and efficient and valid methods of evaluating operative performance await development.
Journal ArticleDOI
The effect of hepatic inflow occlusion on laparoscopic radiofrequency ablation using simulated tumors.
TL;DR: Using a Pringle maneuver during laparoscopic RF ablation significantly enhances ablation geometry and results in larger margins.
Journal ArticleDOI
Surgeon workload and motion efficiency with robot and human laparoscopic camera control.
George V. Kondraske,Elizabeth Costa Hamilton,Daniel J. Scott,C. A. Fischer,S. T. Tesfay,R. Taneja,R. J. Brown,Daniel B. Jones +7 more
TL;DR: In terms of impact on surgeon motion efficiency and operative time under normal surgical conditions, RACC is essentially the same as an expert human driver, however, careful planning and structuring of the surgical suite may yield some small gains in operative time.
