“…This is in agreement with results of a previous study that involved 3 days of training. 6 A training period longer than 2 months might have resulted in significant improvements in the nondominant hand skills of our trainees. There is evidence that experienced surgeons, in comparison with novice surgeons, show better nondominant hand skills in the basic LAP mentor tasks.…”

Keywords: laparoscopic surgery simulator laparoscopy training resident teaching surgical education virtual reality a b s t r a c t Objective: To determine whether our newly developed short-term training program contributes to the acquisition of basic laparoscopic surgery skills. Design: Prospective study (Canadian Task Force Class II). Setting: University Hospital. Participants: Four obstetrics-gynecology residents who participated in our 2-month laparoscopic training course. Interventions: Virtual reality laparoscopic surgery simulator-based assessment of four basic tasks: (1) "camera manipulation"; (2) "eye-hand coordination"; (3) "two-handed maneuvers"; and (4) "cutting," before and after the course. Measurements and main results: Mean times required to perform the tasks before and after training were compared. The mean times required to perform three of the four tasks (except camera manipulation) were significantly reduced after training. Total instrument path lengths were reduced, especially for instruments used by the dominant hand. Conclusion: Use of the virtual reality laparoscopic surgery simulator allowed us to objectively assess residents' acquisition of basic laparoscopic skills. We found that residents more readily acquired dominant-hand skills during their 2-month training. We conclude that our training system serves as an effective initial step towards the acquisition of the necessary laparoscopic surgery skills, even though residents do not actually perform surgeries during the training period.

“…3,4,6,12,13 However, strategies used in general surgery may not be as applicable in spine surgery, where laparoscopic procedures are limited and intricate 3D spinal anatomy is difficult to appropriately replicate on computer simulators. Furthermore, virtual screw placement planning on 2D computer screens has been shown to not clearly translate into an improvement in hands-on performance.…”

OBJECTIVE Pedicle and lateral mass screw placement is technically demanding due to complex 3D spinal anatomy that is not easily visualized. Neurosurgical and orthopedic surgery residents must be properly trained in such procedures, which can be associated with significant complications and associated morbidity. Current training in pedicle and lateral mass screw placement involves didactic teaching and supervised placement in the operating room. The objective of this study was to assess whether teaching residents to place pedicle and lateral mass screws using navigation software, combined with practice using cadaveric specimens and Sawbones models, would improve screw placement accuracy. METHODS This was a single-blinded, prospective, randomized pilot study with 8 junior neurosurgical residents and 2 senior medical students with prior neurosurgery exposure. Both the study group and the level of training-matched control group (each group with 4 level of training-matched residents and 1 senior medical student) were exposed to a standardized didactic education regarding spinal anatomy and screw placement techniques. The study group was exposed to an additional pilot program that included a training session using navigation software combined with cadaveric specimens and accessibility to Sawbones models. RESULTS A statistically significant reduction in overall surgical error was observed in the study group compared with the control group (p = 0.04). Analysis by spinal region demonstrated a significant reduction in surgical error in the thoracic and lumbar regions in the study group compared with controls (p = 0.02 and p = 0.04, respectively). The study group also was observed to place screws more optimally in the cervical, thoracic, and lumbar regions (p = 0.02, p = 0.04, and p = 0.04, respectively). CONCLUSIONS Surgical resident education in pedicle and lateral mass screw placement is a priority for training programs. This study demonstrated that compared with a didactic-only training model, using navigation simulation with cadavers and Sawbones models significantly reduced the number of screw placement errors in a laboratory setting.

“…Characteristic examples include tissue dissection (an inward/outward instrument movement from the tissue being dissected) and camera motion (panning, zooming, etc.). Metrics extracted from camera motion have already been proposed in the literature to evaluate the quality of diagnostic procedures , whereas camera navigation is fundamental in laparoscopic skills acquisition .…”
