Problem
A major limitation of Minimal Invasive Surgery,
is training. The learning laparoscopic surgeon has longer operative time,
higher rate of complications and conversions to open surgery.
Three dimensional (3-D) imaging systems are
believed to improve the surgeon's depth perception, yet they showed no
benefit in clinical studies.
This study aimed to assess their contribution to
the surgeon's learning process, compared
to the familiar 2-D system.
Methods
A novice population performed the rope-passing
task in two sessions. First practice session aimed to achieve the learning
curve using one of the two optic systems, and second session,
one day later, was to evaluate the "latent
phase" of the learning process, while using the 2-D device only.
The performance scored to the time, errors and
subjective impression.
Results
26 medical students divided randomly into two
groups, using the 2-D or 3-D devices in the first session and only 2-D
system in the second session. The average time measured to complete a task after
achieving plateau was 73.1±26.2 and 69.7±25.7 seconds to the 2-D and 3-D
groups respectively (P= 0.46). The second
session results were 89.5±35.6 and 67.2±30.6 seconds for the previously 2-D
and 3-D trained groups respectively (P= 0.14). The error scores showed no
difference.
Conclusions
There was no significant difference in the
learning process, while using the 3-D or the 2-D imaging systems, among
novice.
