“…6 More recently, there has been an influx of tools enabling the objective assessment of psychomotor skills acquisition in both open and laparoscopic surgery. These can be broadly divided into motion analysis systems such as the Imperial College Surgical Assessment Device (ICSAD) 7 and Advanced Dundee Endoscopic Psychomotor Tester (ADEPT), 8 and video-based assessment tools such as Objective Structured Assessment of Technical Skill (OSATS). 9 The ICSAD makes it possible to quantifiably assess surgical dexterity by comparing the performance of experienced and novice surgeons on a simple surgical task.…”

Objective assessment of surgical skill has recently been shown to be possible through the use of dexterity-based and video analysis systems. The aim of this study was to synchronize these 2 modalities to produce a comprehensive surgical assessment tool. Design:The Imperial College Surgical Assessment Device is a dexterity-based motion analysis device that has been developed in the Department of Surgical Oncology and Technology by the Surgical Computing and Imaging Research Group. Further advances to this system have been made to enable synchronized acquisition of hand kinematics and video from real procedures, and their concurrent analysis. To test the feasibility of the system, 10 laparoscopic cholecystectomies performed by 5 different surgeons on consenting patients were recorded. Analysis focused on the entire procedure and also on specific parts of the operation such as the clipping and cutting of the cystic duct and artery.Results: Dexterity analysis was performed using the objective measures of time, path length, number of movements, velocities, and trajectories. Comparative analysis of a surgeon's dexterity was carried out on the whole procedure and by using the synchronized zoom facility in the software. Kinematic signals revealed rapid changes in velocity caused by alternating between different instruments or occurring after complications such as bleeding. Conclusion:This new motion analysis system has been shown to be an effective tool for the comprehensive assessment of operative procedures.

“…More objective methods of assessment are important for the validation of performance. Furthermore, objective measurement methods may identify a person's innate ability for endoscopic task performance [12,15]. Finally, objective measurement methods can be useful in establishing concurrent validity for a variety of laparoscopic training settings, which can vary from the well-known Test-run (run 1) [5,14,16].…”

“…Motion tracking can be based on electromagnetic, mechanical or optical systems. The Advanced Dundee Endoscopic Psychomotor Trainer (ADEPT), another motion tracking system was originally designed as a tool for the selection of trainees for endoscopic surgery, based on the ability of psychomotor tests to predict innate ability to perform relevant tasks (36). Studies have demonstrated the validity and reliability of ADEPT (37,38).…”

The aim of this review was to outline current forms of surgical simulation and methods of assessing technical skills using these forms of simulation. To review this subject, a literature search was done using key words 'assessment', 'simulation', 'surgery', 'technical skills' and 'virtual reality'. Simulation in surgery has several forms, inorganic (synthetic & computer) and organic (animal or cadaver). Surgical simulation is a mode of training which is promising and may be effective. Technical errors in the simulated environment do not have clinical consequences and does not have a morbidity or mortality. We must ensure that the competent skills learnt in the simulation environment are translated to the real environment. This can be achieved if the same assessment tools are used in both environments. Surgical training is entering a new era, with increased scrutiny and an evolving work and training environment. We as surgical teachers must ensure that the surgeons of the future are as competent as or better than their predecessors using these new modes of training which we have access to.
