Visual search behaviour during laparoscopic cadaveric procedures
conference contribution
posted on 2015-11-23, 11:57 authored by Leng Dong, Yan Chen, Alastair Gale, Benjamin Rees, Charles Maxwell-ArmstrongLaparoscopic surgery provides a very complex example of medical image interpretation. The task entails: visually
examining a display that portrays the laparoscopic procedure from a varying viewpoint; eye-hand co-ordination; complex
3D interpretation of the 2D display imagery; efficient and safe usage of appropriate surgical tools, as well as other
factors. Training in laparoscopic surgery typically entails practice using surgical simulators. Another approach is to use
cadavers. Viewing previously recorded laparoscopic operations is also a viable additional approach and to examine this
a study was undertaken to determine what differences exist between where surgeons look during actual operations and
where they look when simply viewing the same pre-recorded operations. It was hypothesised that there would be
differences related to the different experimental conditions; however the relative nature of such differences was
unknown. The visual search behaviour of two experienced surgeons was recorded as they performed three types of
laparoscopic operations on a cadaver. The operations were also digitally recorded. Subsequently they viewed the
recording of their operations, again whilst their eye movements were monitored. Differences were found in various eye
movement parameters when the two surgeons performed the operations and where they looked when they simply
watched the recordings of the operations. It is argued that this reflects the different perceptual motor skills pertinent to
the different situations. The relevance of this for surgical training is explored.
