Development of a model for training and evaluation of laparoscopic skills.
Interest in the training and evaluation of laparoscopic skills is extending beyond the realm of the operating room to the use of laparoscopic simulators.
The purpose of this study was to develop a series of structured tasks to objectively measure laparoscopic skills.
This model was then used to test for the effects of level of training and practice on performance.
Forty-two subjects (6 each of surgical residents PGY1 to PGY5,6 surgeons who practice laparoscopy and 6 who do not) were evaluated.
Each subject viewed a 20-minute introductory video, then was tested performing 7 laparoscopic tasks (peg transfers, pattem cutting, clip and divide, endolooping, mesh placement and fixation, suturing with intracorporeal or extracorporeal knots).
Performance was measured using a scoring system rewarding precision and speed.
Each candidate repeated all 7 tasks and was rescored.
Data were analyzed by linear regression to assess the relationship of performance with level of residency training for each task, and by ANOVA with repeated measures to test for effects of level of training, of repetition, and of the interaction between level of training and repetition on overall performance.
Student's t test was used to evaluate differences between laparoscopic and nonlaparoscopic surgeons and between each of these groups and the PGY 5 level of surgical residents.
Significant predictors of overall performance were (a) level of training (P=0. (...)
