MP19-6 - Construct validation study of a simulation model using swine tissue for laparoscopic dissection and suturing training

Saturday, September 22
2:00 PM - 4:00 PM
Location: Room 241

Introduction & Objective :  Based on recent developments of surgical practice including laparoscopic procedures, working-hour restrictions, and ethical considerations, there is a growing need for surgical training outside the operating theater.  We recently started a laparoscopic training program using swine tissue.  The aim of this study was to evaluate the construct validity of our training model.


Methods : Since June 2017, using swine aortas and kidneys, we have provided simulation training to promote laparoscopic surgical skills.  So far, 11 experts (performed >50 laparoscopic surgeries), 6 intermediates (performed 11-49), and 22 novices (performed 0-10) have voluntarily joined this training program.  Participants were required to perform lymphadenectomy around the aorta (task-1), dissection and division of the renal artery (task-2), and renal parenchymal closure (task-3). Training sessions were video-recorded, performances were blindly evaluated by two experts (TA and KH), according to a score sheet that we developed (Table 1), and mean scores were used for subsequent analysis.  The inter-class coefficient (ICC) was evaluated for inter-rater reliability, and mean scores for the initial training session were compared among the three groups for construct validation.


Results : Thirty-nine performed a total of 56 training sessions, and the 55 sessions were successfully video-recorded.  In task-2, 6 sessions could not be performed due to the conditions of kidneys.  Therefore, a total of 159 movies (task-1/ 2/ 3= 55/ 49/ 55 movies) were independently assessed by the two raters.  For inter-rater reliability, the score assigned by each rater had an ICC of 0.741.  For construct validity, in all 3 tasks, there were significant differences in the total scores among groups (Kruskal-Wallis test, p<0.0001).


Conclusions : The present study showed the construct validity of our swine tissue training model.  The good inter-rater reliability may allow us to use it as an assessment tool.
