Abstract
A significant limitation of minimally invasive surgery is dependence of the entire surgical team on a single endoscopic viewpoint. An individualized, instrument-driven image display system that allows all operators to simultaneously define their viewing frame of the surgical field may be the solution. We tested the efficacy of such a system using a modified Fundamentals of Laparoscopic Surgery™ (Society of American Gastrointestinal and Endoscopic Surgeons, Los Angeles, CA) bead transfer task.
A program was custom-written to allow zooming and centering of the image window on specific color signals, each attached near the tip of a different laparoscopic instrument. Two controls were used for the bead transfer task: (1) a static, wide-angle view and (2) a single moving camera allowing close-up and tracking of the bead as it was transferred. Time to task completion and number of bead drops were recorded.
Thirty-six sessions were performed by surgical residents. Average time for bead transfer was 127.3±21.3 seconds in the Experimental group, 139.1±27.8 seconds in the Control 1 group, and 186.2±18.5 seconds in the Control 2 group (P=.034, by analysis of variance). Paired analysis (the Wilcoxon Signed-Rank Test) showed that the Experimental group was significantly faster than the Control 1 group (P=.035) and the Control 2 group (P=.028).
We have developed an image navigation system that allows intuitive and efficient laparoscopic performance compared with two controls. It offers high-resolution images and ability for multitasking. The tracking system centers close-up images on the laparoscopic target. Further development of robust prototypes will help transition this in vitro system into clinical application.
