Traditionally, surgical training has been a matter of apprenticeship. The surgical trainee learned to perform surgery under the supervision of a trained surgeon until he or she was believed capable of performing surgery independently. The opinion of the supervising surgeon was about the only informal standard that had to be met—a standard hard to define, second to none, but the hand of God himself, as perceived both within and without surgical societies. This is illustrated by literature, in which a capital for “Surgeon” is allowed in both ancient and recent publications [1‐3].
At the beginning of the new millennium, a paradigm shift in medical education thinking became apparent. Public opinion developed into a powerful force, a force affected by messages such as the rate of iatrogenic complications in U.S. hospitals. If extrapolated to the airline industry, this would be the equivalent of three large jet crashes every two days [4].

In addition, patient safety and quality-of-care movements together with forces from technological innovation and governmental attention demanded safer and more transparent health care systems, systems whose very foundation must be build on the principle of accountability, hence, systems able and actively seeking for self-reflection of performance. Consequently, these must be systems that actively seek for opportunities to improve medical education and thereby ultimately create optimal conditions for near-future patient care [5‐7].
The combination of the aforementioned forces, all stressing the need to reform medical education, led to the development of standards for physician competence.
Competency frameworks
Surgical institutions and organizations were challenged to define the competencies required by the public and medical educators, competencies needed by surgeons to best meet the needs of their patients. The Royal College of Physicians and Surgeons of Canada (RCPSC) was the first organization to take up this challenge systematically. This resulted in a competency framework design called the Canadian Medical Education Directions for Specialists (CanMEDS) project [7].
The focus of CanMEDS is on articulating a comprehensive definition of the competencies needed for medical education and practice [8]. In 1996, the Council of the RCPSC formally accepted CanMEDS as the foundational framework for its educational mission.

The CanMEDS framework is organized around seven roles: medical expert (central role), communicator, collaborator, health advocate, manager, scholar, and professional. CanMEDS makes explicit the abilities long recognized in highly skilled physicians and constantly updates them for today’s—and tomorrow’s—medicine. As such, the CanMEDS framework was extensively reviewed, updated, and launched in September 2005.
The CanMEDS competencies currently are integrated into the Royal College’s accreditation standards, objectives of training, final in-training evaluations, exam blueprints, and the maintenance-of-certification program. Several countries, including Denmark, the Netherlands, Australia and New Zealand, have used the CanMEDS competence framework as a model for specialist education.
With the advent of new frameworks for defining the outcomes of surgical training, such as CanMEDS from the RCPSC and the newer six-role-based competency framework from the Accreditation Council for Graduate Medical Education (ACGME) in the United States, approved by the ACGME Board in 2007, the focus of surgical training has been broadened [9].
In fact, medical boards around the world face the challenge of creating competency-based postgraduate training programs; driven by recent legislations [10]. Consequently, training programs are rewritten largely according to CanMEDS or some other competency-based medical education framework [11, 12].
Competency in modern laparoscopic surgery
The aim of a modern surgical residency program must be to produce competent professionals in a safe and pedagogically efficient environment [13]. The traditional approach based on the apprenticeship model is not only obsolete; it simply cannot accommodate the skills required in performing laparoscopic surgery [14]. Recent history has made this clear.
The first reported laparoscopic cholecystectomy was performed by Philippe Mouret in 1987 [15], and within five years, the laparoscopic approach was established as a feasible alternative to open cholecystectomy. Few surgeons attempting this exciting new technique had seen a laparoscopic cholecystectomy but were eager to start with it nonetheless [14]. The assumption that the technical skills derived from open surgery and knowledge of the operating area would transfer to the laparoscopic environment proved to be untrue as the ratio and severity of bile duct lesions increased after its hazardous introduction into surgical practice [16, 17].
Laparoscopic surgery may appear to be a modern type of surgery in many respects. In contrast, however, early training for this modern technique has been very traditional, exposing patients to an increased chance of serious injury. Over time, however, laparoscopic cholecystectomy became the gold standard for uncomplicated cholecystolithiasis [18].
Surgeons of the younger generation taught by the initial early adopters of the laparoscopic technique currently are better acquainted and more comfortable with the laparoscopic procedure than the open approach [19]. Ideally, they have overcome the asymptote of their learning curve for this specific type of surgery outside the operating room, but in general, this is not the case. Ideally, residents’ competence is evaluated properly before they engage laparoscopic surgery independently. But again, this still is far from customary [20‐22].
Anzeige
Fortunately, both surgeons and surgical residents do subscribe to the importance of training and examining laparoscopic procedural skill outside the operating theatre [14, 23, 24]. Why then is it so difficult to get people trained to achieve a minimal level of competency outside the operating room before they engage in surgery?
Problems and pitfalls for laparoscopic training outlined
Adopting competency frameworks
Information about the validity of CanMEDS in an international context is sparse, and little is known about how the aspects of the seven roles apply to various stages of trainees’ development into specialists [25]. A rational internal validation was called for but cannot not be found in literature to date. In fact, little is known about the surgeon’s perception of competence. Although technical proficiency definitely is considered an important prerequisite for a successful outcome, other qualities such as intellectual abilities, personality, communication skills, and a commitment to practice are important elements in the profile of a competent endoscopic surgeon. Not much is known about the relative contribution of each role to surgical competency [26]. A recent study by Chou et al. [27] showed that program directors are neutral or even concerned about how the CanMEDS roles other than the central role of medical expert are to be evaluated in their programs.
In addition to program directors, residents’ knowledge of CanMEDS itself is limited. Residents’ familiarity with the set of competencies appears to be quite limited, and knowledge about definitions of the roles is scarce [28]. The importance of being competent in all the roles required for a surgeon to be a competent is not appreciated by trainees [26] despite evidence showing that nontechnical competence (roles of communication, collaboration within a team) is the most important factor for patient safety and prevention of legal claims [29, 30]. Residents incorrectly perceive the central medical expert role as the most relevant and important competency, falsely believing that it represents the acquisition of medical and scientific knowledge [28].
Current training is not believed to ensure competence in all roles, nor do surgeons believe it ensures achievement of competency in every CanMEDS role [26]. Moreover, the framework’s relevance itself has been questioned, and confusion exists about the overlapping nature of the roles. Furthermore, a variety of nonvalidated assessment tools appear to be of use in addressing the various CanMEDS roles [27].
Anzeige
At best, it might be concluded that an apparent distortion of the original CanMEDS construct from its original holistic philosophy exists within the surgical community. This is a genuine threat to any competency framework acceptance for surgical training. Without an understanding of the concepts, how can a competency framework gain credits for implementation? Moreover, how can issues such as standardization of competency measurement and accreditation be handled?
Training outside the operating room
Any form of surgical training, inside or outside the operating room, is time consuming, costly, and of variable effectiveness. As mentioned previously, surgical organizations are calling for methods to ensure the development and maintenance of skills, advance surgical training, and credential surgeons as competent [31].
Training by use of a virtual reality simulator is an option for supplementing standard training with the use of box trainers (limited in fidelity) or porcine in vivo or ex vivo setups (high in fidelity, but costly and controversial) in a surgical training curriculum. Indeed, virtual reality simulators are promising and potent tools for training residents in laparoscopy and endoscopy [32‐35]. They enable trainees to perform standardized, reproducible virtual laparoscopic and endoscopic procedures ranging from basic task drills to full laparoscopic and endoscopic procedures with varying patient scenarios.
Simulators provide trainees with immediate, structured, objective feedback after each repetition, allowing performance to be tracked over time or compared with a benchmark often set by experts [36‐38].Virtual reality training systems are intended to create new experiential learning opportunities that can serve as safe and effective alternatives to more traditional learning venues, such as the clinical operating room [32].
Anzeige
A recent systematic review of randomized controlled trials on the effectiveness of virtual reality training for laparoscopic surgery showed that such training resulted in a greater reduction in operating time, error, and unnecessary movements than standard non–virtual reality laparoscopic training [39]. Multiple studies have shown that skills acquired by simulation-based training are transferable to the operative setting [22, 33, 40, 41]. Worldwide, the belief is growing that virtual reality simulator training is an indispensable component of diverse endoscopic surgical training curricula [42], and is likely eventually to be a mandatory component of residency training in the surgical specialities [43‐46].
A recent randomized controlled trial by Snyder et al. [47] showed that proctored instruction using virtual reality simulators does not offer any advantages to trainees in terms of achieving expert level proficiency with laparoscopic and endoscopic simulators. It is stated that the independent approach may be preferable for surgical residency programs desiring to implement virtual reality simulator training. This finding suggests that self-directed repetitive practice rather than expert instruction is the driving factor for simulator proficiency. Furthermore, development of skill is likely to be augmented by reviewing recordings of one’s earlier attempts [48].
In the end, surgical trainees need a simulator proved to be valid by methodically sound studies and also proved to be valid for the course/curriculum in which it is used. Not embedding simulators in a curriculum essentially means no use of a simulator whatsoever [45].
Given the challenges of meeting surgical education requirements within the resident duty hour restrictions currently in place in the United States, Canada, and Europe, the independent but embedded approach may represent an optimal method for integrating simulator training into surgical residency programs. Electronic, open-platform surgical portfolios capable of online integration of training results with virtual reality simulators are key for easy surgical monitoring of technical competence.
Cost effectiveness of training
From the societal perspective, laparoscopic surgery saves money, but from a hospital point of view, the open operation often is less costly than its laparoscopic alternative [49‐54]. Hospitals do not have economic incentives to adopt new technology because benefits accrue not to the hospital but to the insurance sector or the patients’ employer. Patients, however, usually gain from the laparoscopic variant of a surgical procedure in terms of less pain, shorter hospital stay and recovery time, and better cosmesis.
Ultimately, patients undergoing elective surgery may not want to have surgery at centers not offering laparoscopic surgery for their problem or at centers not known as experienced in this area. Insurance companies may not agree to pay for operations unless centers are visibly labeled as having expertise in the area. Such centers may have to show the number of procedures performed, complication rates, and certified training programs followed by the surgeons working in it.
It might be appropriate to invest in training surgeons and their operating team for specific laparoscopic procedures. Competency-based training not only shortens operation time (hospital incentive) but ultimately increases patient safety (both a patient and a hospital incentive) and certifies surgeons that have successfully followed such a course. Insurance or governmental support and monitoring are important factors in selecting and funding such hospitals and training curricula. Moreover, governments that do not allow surgical procedures to be performed in centers that offer no credible information on the laparoscopic surgical competency of residents might speed up the process of implementing valid training initiatives tremendously.
Conclusions and recommendations
In conclusion, much work needs to be done before the claim that CanMEDS is an accepted accreditation standard with regard to objectives of training, final in-training evaluations, exam blueprints, and maintenance of certification can be considered truly legitimate in laparoscopic surgery. Competency-based curricula for key laparoscopic procedures need to be developed. National or European societies must determine which procedures are in fact key to be mastered by surgical residents and in which phase of their education.
In these specific training curricula, CanMEDS roles need to be stated clearly, addressed specifically, and tailored appropriately for the particular procedure. Team training that focuses on the roles of communicator and collaborator in the operating room must be addressed. Knowledge of the procedure may be transferred by proctored instruction, but the electronic open portfolio might be very useful in administering and examining the use of multimodality E-learning modules. Technical skill training must be embedded in a curriculum, allowing for repetitive practice.
Examination of such a curriculum needs different examination instruments. Knowledge may be examined using questionnaires. A promising type of knowledge testing uses comprehensive integrated puzzling (CIP), which eliminates the element of chance known to be present in multiple-choice examinations. Technical surgical skill must be assessed objectively using validated examination procedures. Objective surgical assessment of technical skills (OSATS) examination stations may be developed for the specific procedure; or performance can be evaluated by validated procedure-specific virtual reality simulators. A patient management examination (PAME) needs to be integrated into the exam. A PAME uses simulative patients in a patient setting, demanding mastery of the clinical outpatient setting by the examination candidate.
This type of examination is needed to verify the mastery of competencies such as being competent in the roles of communicator, collaborator, health advocate, manager, scholar, and professional [55]. Residents should not be allowed to operate on patients unsupervised unless they are proven competent by having successfully passed at least their technical surgical skills examinations. Surgical residents that excel in one area of competence but lack in other competencies may need to shift priorities in their training curriculum. Examinations are therefore indispensable and may function to tailor the curriculum even further to each individual.
Only when aforementioned conditions are met can a curriculum truly produce the medical experts that our society demands, and most importantly, that our patients need.
