Background |
Within surgery, several specialties demand advanced technical skills, specifically in the minimally invasive environment.
Methods |
Two groups of 10 medical students were recruited on the basis of their aptitude (visual-spatial ability, depth perception, and psychomotor ability). All subjects were tested consecutively using the ProMIS III simulator until they reached proficiency performing laparoscopic suturing. Simulator metrics, critical error scores, observed structured assessment of technical skills scores, and Fundamentals of Laparoscopic Surgery scores were recorded.
Results |
Group A (high aptitude) achieved proficiency after a mean of 7 attempts (range, 4–10). In group B (low aptitude), 30% achieved proficiency after a mean of 14 attempts (range, 10–16). In group B, 40% demonstrated improvement but did not attain proficiency, and 30% failed to progress.
Conclusions |
Distinct learning curves for laparoscopic suturing can be mapped on the basis of fundamental ability. High aptitude is directly related to earlier completion of the learning curve. A proportion of subjects with low aptitude are unable to reach proficiency despite repeated attempts.
