Purpose:
The aim of this study was to compare skills sets during a hand-assisted and straight laparoscopic colectomy on an augmented reality simulator.
Methods:
Twenty-nine surgeons, assigned randomly in 2 groups, performed laparoscopic sigmoid colectomies on a simulator: group A (n = 15) performed hand-assisted then straight procedures; group B (n = 14) performed straight then hand-assisted procedures. Groups were compared according to prior laparoscopic colorectal experience, performance (time, instrument path length, and instrument velocity changes), technical skills, and operative error.
Results:
Prior laparoscopic colorectal experience was similar in both groups. Both groups had better performances with the hand-assisted approach, although technical skill scores were similar between approaches. The error rate was higher with the hand-assisted approach in group A, but similar between both approaches in group B.
Conclusions:
These data define the metrics of performance for hand-assisted and straight laparoscopic colectomy on an augmented reality simulator. The improved scores with the hand-assisted approach suggest that with this simulator a hand-assisted model may be technically easier to perform, although it is associated with increased intraoperative errors.
