Background: Numerous obstacles exist for learning the principles
and technical skills necessary for minimally invasive operations. This
challenges the traditional teaching model solely in the operating room. Also,
well preparing the residents prior to entering the operating room should
improve surgical time, skills, and patient safety.
Methods: A prospective interventional study, performed at an
academic affiliated community hospital. We administered a pre-intervention test
to 20 OBGYN residents (10 junior and 10 senior). The questions pertained to
fundamental principles of laparoscopy including patient positioning and related
nerve injuries, electrosurgery, laparoscopic equipment, physiological
considerations, and laparoscopic complications. After the course of the
academic year, all the residents were administered a post-intervention exam.
Test scores were compared, averages calculated, and t-test applied.
Results: In the first stage, the average pretest score for
junior residents was 35%, and for seniors was 42.14%. Nonetheless, the average
posttest score for junior residents was 75.71%, and for seniors was 48,70%.
This means the junior residents group improved 40,71%, while the senior
residents improved 6,42%. T-test was applied, and showed statiscally
significant difference (t-value=5.20; p=0.00003).
Discussions: Introducing a laparoscopic curriculum to a residency
program has a significant impact on improving resident knowledge of the
fundamental principles of laparoscopy, more so than the traditional method.
Future studies are underway to evaluate the effect of a structured simulation
course on resident operating room performance.
