This study was designed to evaluate the impact of 3-dimensional vision on the performance of resident and experienced surgeons using the da Vinci Robot System (Intuitive Surgical, Sunnyvale, CA).
Four tasks were performed by 12 surgeons with varying experience. Performance times and errors were recorded using both 2-dimensional and 3-dimensional vision for each task.
Performance time and error rates for all 4 skills confirm a significant advantage using 3-dimensional vision. Performance times were reduced by 34% to 46% using 3-dimensional imaging for all participants with statistical significance. Error rates were reduced by 44% and 66%.
Independent of the biomechanical advantages of the da Vinci Robot System, 3-dimensional vision allows for significant improvement in performance times and error rates for both inexperienced residents and advanced laparoscopic surgeons.

    • "Recently, these devices gained popularity among clinicians because of new technological developments. In particular, a laparoscopic operation involving 3D endoscopy has become more common due to the introduction of the da Vinci System (Intuitive Surgical, Sunnyvale, CA, USA) [10]. The dissemination of neuroendoscopy in the field of neurosurgery has accelerated improvements of the endoscopic devices. "

    ABSTRACT: To examine the efficacy of a three-dimensional (3D) endoscope for endoscopic sinus and skull base surgery.Methods The study design was a retrospective case series and qualitative research. The clinical efficacy of 3D endoscopes was examined on five cadavers. We performed conventional endoscopic sinus surgery (ESS) in five cases and hypophysectomy in two cases using a 3D endoscope. The educational advantages of the 3D endoscope were assessed using questionnaires given to the participants of cadaver dissection courses.ResultsIn the posterior portion of the nasal cavity, images captured via 3D endoscopy provided a superior perception of depth of information than those via two-dimensional (2D) endoscopy. All endonasal surgeries were completed in clinical settings using a 3D endoscope without perioperative complications. In terms of the operative time and amount of bleeding, the results of 3D endoscopic surgeries were not inferior to those of 2D endoscopic surgeries. Fatigue from 3D viewing through polarized glasses did not adversely affect performance of the surgery. Moreover, questionnaires for the evaluation of educational efficacy were completed by 73 surgeons. Of the respondents, 89% agreed that 3D endoscopy provided a better understanding of the surgical anatomy than did 2D endoscopy. As for the site where 3D endoscopy would be the most useful for understanding surgical anatomy, 40% of the respondents named the skull base; 29%, the posterior ethmoid sinuses; and 26%, the sphenoid sinus; and 9%, the ethmoid bulla and middle turbinate.Conclusion The 3D endoscope contributes to a more precise anatomical understanding of the posterior structures of the sinuses and skull base and ensures a more precise operation of the instruments. Thus, 3D endoscopes will likely become a standard device for endonasal surgery in the near future.

    • "Similarly, operative time interval for other procedures of two groups was compared [Table/Fig-3]. As single surgeon carried out all the procedures, a comparative evaluation was made in terms of operative imaging parameters like image quality, depth of perception, operative strain including laparoscopic surgeons surmount this by extracting 'pictorial' depth cues from conventional images [4] [5].

    ABSTRACT: Introduction: To evaluate the advantages of 3D laparoscopy and compare its significance with conventional 2D laparoscopy during various operative procedures. Methods: During present study, two groups were formed. Group A included patients who were operated using 3D laparoscopic imaging and Group B consisted of operated patients by 2D laparoscopy. Operative performance of both the groups was compared in terms of operative time and quality of imaging. Results: Operative time interval for various procedures was significantly less in Group A as compared to Group B. Also, imaging quality was far superior with use of 3D imaging system especially in terms of depth perception. Conclusion: Advantages of 3D laparoscopy are well appreciated during operative procedures as previously documented by other studies in training models.

    • "Anatomic drills were completed 65% faster[15] and the time to perform the task was significantly shorter in the group that used a 3D view.[16] Independent of the biomechanical advantages of the da Vinci robot system, 3D vision was found to improve performance times by 34-46% and reduce error rates by 44-66% for both inexperienced residents and experienced laparoscopic surgeons.[6] "

    ABSTRACT: One of the main benefits of robotic surgery is the surgeon's three-dimensional (3D) vision system. The purpose of this study is to evaluate the efficacy of 3D vision using a flat screen and polarized glasses for surgical skills during robotic surgeries. In an experimental model, six surgeons performed three surgical tasks with laparoscopic devices using a standard 2D and a flat-screen 3D model with polarized glasses. Performance times were compared between two-dimensional (2D) and 3D vision for each task. The surgeons also graded the efficiency of the 3D system, on a subjective scale of 0-100. Performance times for task 1 (seven holes) and 2 (elastic bands) were significantly reduced by 84% and 56% using 3D compared with a 2D system and experienced surgeons performed all three tasks faster in 3D than 2D. The surgeons reported the polarized glasses were comfortable to wear and direct vision was seldom affected. The use of 3D visualization seems to improve the efficiency of surgical skills during robotic surgery and reduce performance time for characteristic surgical procedure tasks.
