Evaluation of Laparoscopic Hysterectomy Simulator

This study aims to test the validity of a new educational tool in the form of a computer based video surgical simulator, that may be used to enhance the current teaching method of how to perform a hysterectomy.

Ensuring the surgical competence of trainees is mandatory for all surgical residency programs, yet most evaluations of graduating residents are based on observation and subjective feedback. We have developed a computer based video surgical simulator to facilitate cognitive knowledge of the step-by-step process needed to perform a laparoscopic hysterectomy, learn essential pelvic anatomy and avoid surgical complications. Studies have shown that when trainees already have the cognitive knowledge of how to perform a procedure, they can focus more on learning surgical technique and how to minimize surgical complications. Laparoscopy is becoming the standard of surgical care for gynecologic patients. The benefits of minimally invasive surgery include reduced postoperative pain, shorter hospitalization, less scarring, quicker return to normal activities, preservation of immune response, and fewer long-term problems such as adhesions or incisional hernia. The current challenge in surgical education is how to produce competent surgeons who are skilled to perform and integrate the multiple advances in surgical technology. Surgical competency involves proficiency in technical skills, decision-making (preoperative, operative, and postoperative), and team performance all of which require knowledge and communication skills. The increasing complexity of surgery and the requirements for mastery at laparotomy, laparoscopy, and endoscopy reduces the feasibility of the traditional "see one, do one, teach one" model of surgical education. Lack of training is considered a major barrier to performing laparoscopic surgery. Alternative training modalities are required to acquire the necessary surgical skills for laparoscopy. Although there is a transfer of skills and knowledge to the trainee by the time of graduation, current training programs have not been designed in a validated, effective, and competency-based manner. A successful laparoscopic curriculum should incorporate a cognitive component in addition to the manual skills component. Although the benefit of simulators as a method of surgical education has been validated, comprehensive curriculum development is lacking. Most recently, Zevin et al. (2012) conducted a Delphi consensus involving international experts in surgical education on the principles for design, validation and implementation of a simulation-based surgical training curriculum. The main components of the final framework included predevelopment analysis; cognitive, psychomotor, and team-based training; curriculum validation, evaluation, and improvement; and maintenance of training. They have produced a framework that is based on the broad principles of educational theory that can be applied to any surgical specialty. Several authors have emphasized the importance of cognitive teaching in a comprehensive surgical skills training curriculum. Learning begins with the acquisition of procedure-specific knowledge. Categories include pre-procedure assessment and preparation; anatomic knowledge; safety and limitations of specific instruments; ergonomics; and post-procedure management. A cognitive curriculum can include reading materials in the form of text books or journal articles as well as procedural video tutorials. The cognitive component should be studied by the trainee before technical skills training and should be followed by satisfactory performance on a paper-based test of knowledge or a mock operative note dictation. Teaching about errors commonly associated with the procedure should be included so that trainees can anticipate or avoid them in the future, and recognize and manage them if they occur. The purpose of this research study is to test the validity of a new educational tool as an enhancement to the current teaching method of how to perform a hysterectomy. Should our data substantiate our hypothesis, that cognitive function of surgical trainees will be enhanced by use of the trainer, then the tool will be able to be utilized as a new, advanced, creative tool for teaching how to perform a hysterectomy. This tool might then be able to be utilized to advance the teaching of many other surgical procedures to residents in many different surgical programs.
