Surgeons with minimal endovascular experience can improve their time taken and contrast usage during short-phase training on a VR endovascular task. VR simulation may be useful for the early part of the learning curve for surgeons who wish to expand their endovascular interests.

Objective: To evaluate motion tracking as an aid to a more objective assessment of ophthalmic microsurgical skill. Methods: In a cohort study, 3 groups of differing levels of surgical experience were assessed. The groups included novice surgeons (n = 10) with fewer than 5 previously performed corneal sutures, trainee surgeons (n=10) with 5 to 100 previously performed corneal sutures, and expert surgeons (n = 10) with more than 100 previously performed corneal sutures. The Imperial College Surgical Assessment Device was used for the objective assessment of surgical dexterity during corneal suturing. Each of the subjects used a 10-0 nylon suture in a 3-1-1 pattern on an artificial eye (Royal College of Ophthalmologists, London, England). The Imperial College Surgical Assessment Device measures 3-dimensional spatial vectors via electromagnetic sensors attached to the surgeon's fingers. The number of movements, path length for the respective movements, and time taken to complete the given task were recorded. Results: Highly statistically significant differences were found between the 3 grades of surgeon experience for time taken (PϽ.001), number of hand movements (PϽ.001), and path length of the hand movements (P=.002) to complete the given task. Conclusions: Motion analysis measured by this technology may be useful in the formal surgical training of residents and as an objective quantitative measure of dexterity.

The use of bench-top tasks to differentiate between cardiac surgeons of differing technical abilities has been validated for the first time. Furthermore, it is unnecessary to perform post-hoc video rating to obtain objective data. These measures can provide formative feedback for surgeons-in-training and lead to the development of a competency-based technical skills curriculum.

The structured, task-based approach for commencement of training in LRYGBP leads to objective improvements in the technical skills of inexperienced surgeons at the end of a short course. The next stage of the curriculum should be to achieve proficiency in the complete procedure on an anesthetised porcine model, prior to preceptorship on human cases.

This examination successfully differentiated surgical skill, both between surgeons with different grades of experience and within the target study group of specialist trainees. The examination is feasible in terms of the timeframe needed to complete tasks, cost, and efficiency in performing video-based assessments.
