简要总结
Surgical practice training often suffers from poor educational efficiency due to the technical difficulties of the cases, the lack of resources and the cases in the operating room. The video editing training method is not included in the standard surgical training, but it has the advantage of reducing trial and error and errors during surgery, simplifying training time, and cost-effective. Investigators analyzed whether the video editing teaching method has effective value for trainees compared to the traditional teaching method.
The primary purpose of the study is the trainee's learning achievement in terms of surgical skills. Learning achievement is measured as the difference in pre- and post-educational test scores (The Global Operative Assessment of Laparoscopic Skills (GOALS)) to compare the difference in achievement.
The secondary objective of the study was to evaluate the satisfaction with the video editing method as an educational method by conducting a questionnaire survey to all the trainees participating in the study. In addition, the degree of postoperative pain, postoperative hospitalization period, postoperative readmission and the need for additional procedures were compared and analyzed.
详细描述
- background Traditional education teaches surgery in a one-on-one apprenticeship of surgeons and practitioners, in which the surgeon learns to perform surgical operations under the supervision of a qualified surgeon. The supervisor surgeon instructs the trainee and, if necessary, temporarily takes over the procedure to show the difficult steps. Today, a proven educational platform has been established to prevent the risk of patients being exposed to the early learning curve, allowing trainees to sufficiently hone their basic skills in open and laparoscopic surgery.
Laparoscopic surgery requires complex techniques and techniques that are not used in open surgery. Laparoscopic instruments provide limited haptic feedback, lack of freedom, and video monitors that provide a two-dimensional projection of the operating room impair depth perception, making surgery more difficult. Therefore, surgeons must master these technical challenges before performing laparoscopic procedures properly and safely.
Animal model training and cadaver training are very useful, but have the disadvantages of being small in number and expensive to use. On the other hand, books, the Internet, and educational videos have the advantage of being able to provide important basic knowledge about disease and surgical treatment, but the most important factor in training specific surgical procedures is from the trainee side to the real patient together with an experienced surgeon Since it is a practical training for Korea, the teaching method still used is the apprenticeship method. The main drawback of this traditional approach is that the trainee or supervising surgeon can only perform the step once per operation. When the supervisor takes over, the memories of training with the trainee who have to wait for the next task to be performed are lost.
Therefore, investigators devised a new training method called surgical video editing in order to minimize the frequency of supervisor intervention and maximize the actual surgical practice time of the trainee. This method is used by the trainee himself to review the surgical process, Since the essential skills can be recalled and learned, it can have the effect that the trainee can easily learn the surgery during the actual surgery. 2.
