OBJECTIVETo compare the last generation of 3-dimensional imaging (3D) vs standard 2-dimensional imaging (2D) laparoscopy. MATERIALS AND METHODSA prospective observational study was conducted during the 4th Minimally Invasive Urological Surgical Week Course held in Braga (Portugal) in April 2013. The course participants and faculty were asked to perform standardized tasks in the dry laboratory setting and randomly assigned into 2 study groups; one starting with 3D, the other with 2D laparoscopy. The 5 tasks of the European Training in Basic Laparoscopic Urological Skills were performed. Time to complete each task and errors made were recorded and analyzed. An end-of-study questionnaire was filled by the participants. RESULTSTen laparoscopic experts and 23 laparoscopy-naïve residents were included. Overall, a significantly better performance was obtained using 3D in terms of time (1115 seconds, interquartile range [IQR] 596-1469 vs 1299 seconds, IQR 620-1723; P ¼ .027) and number of errors (2, IQR 1-3 vs 3, IQR 2-5.5; P ¼ .001). However, the experts were faster only in the "peg transfer" task when using the 3D, whereas naïves improved their performance in 3 of the 5 tasks. A linear correlation between level of experience and performance was found. Threedimensional imaging was perceived as "easier" by a third of the laparoscopy-naïve participants (P ¼ .027). L aparoscopy has been increasingly adopted in urology over the last 2 decades, and it is nowadays commonly used in the management of several urologic diseases. Traditionally, laparoscopy has been based on 2-dimensional (2D) imaging, which has represented a considerable challenge for those approaching this technique.1 Thus, 3-dimensional (3D) visualization technology for laparoscopy has been proposed, since the early 1990s, as a way to facilitate laparoscopic performance. However, early 3D laparoscopic technology was limited in terms of image quality, so that its use had not been implemented. 2More recently, industry has developed novel 3D systems where the imaging is similar to stereoscopic vision, in which the depth perception is achieved by different unique images received by each eye. Thus, more recent studies have suggested a possible advantage provided by these new 3D systems during laparoscopic performance.3-5 However, comparative assessments of new generation 3D vs 2D laparoscopy remain limited, especially in the urology field.

“…During the SILS, frequent movement of camera scope is more limited compared to conventional multiport laparoscopic surgery because of collision of instruments. Recently developed 3D scope system could be useful in terms of superior task efficiency because it can show more effective perspective and depth of field to operator, which means the decreased number of "air-catching" and less position change of camera scope (29)(30)(31). Secondly, the length and shape of instrument can be chosen depending on the situation.…”

Based on rapid development of laparoscopic techniques and instruments, single-incision laparoscopic surgery (SILS) is expected to be the next step of "more" minimally invasive surgery. A few institutions gradually started to report their experience of single incision gastrectomy (SIG) for gastric cancer, but it is still difficult to accept that SIG can be performed as a popular procedure because of its technical difficulty. For wide adoption of SIG, the simplicity, safety and reproducibility of not only lymph node dissection but also reconstruction should be evaluated compared to a conventional procedure. With a thorough understanding of unique characteristics of SILS, single incision distal gastrectomy (SIDG) for early gastric cancer performed by laparoscopic surgeons with advanced technique is expected to have promising potential about excellent cosmesis, comparable morbidity and mortality in carefully selected patients. For appropriate adoption and steady progress of this state-of-the art surgery, scientific evaluation with healthy critics is necessary with new generation of SILS instrument platform.

“…Various reports in the existing literature have already shown that stereoscopic vision decreases surgery time and increases accuracy for the surgeon behind the console of the Da Vinci robot. [3][4][5][6][7][8][9][10] However, to the best of our knowledge to date, there is little or no published evidence illustrating the impact of using a 3-D auxiliary monitor for the assistant(s) at the operating table during robot-assisted laparoscopy (RAL). For the assistant(s), these facilities are not currently widely available, although it seems some 3-D auxiliary monitor systems are beginning to emerge on the market.…”

Abstract.In comparison to open surgery, endoscopic surgery offers impaired depth perception and narrower field-of-view. To improve depth perception, the Da Vinci robot offers three-dimensional (3-D) video on the console for the surgeon but not for assistants, although both must collaborate. We improved the shared perception of the whole surgical team by connecting live 3-D monitors to all three available Da Vinci generations, probed user experience after two years by questionnaire, and compared time measurements of a predefined complex interaction task performed with a 3-D monitor versus two-dimensional. Additionally, we investigated whether the complex mental task of reconstructing a 3-D overview from an endoscopic video can be performed by a computer and shared among users. During the study, 925 robot-assisted laparoscopic procedures were performed in three hospitals, including prostatectomies, cystectomies, and nephrectomies. Thirty-one users participated in our questionnaire. Eighty-four percent preferred 3-D monitors and 100% reported spatial-perception improvement. All participating urologists indicated quicker performance of tasks requiring delicate collaboration (e.g., clip placement) when assistants used 3-D monitors. Eighteen users participated in a timing experiment during a delicate cooperation task in vitro. Teamwork was significantly (40%) faster with the 3-D monitor. Computer-generated 3-D reconstructions from recordings offered very wide interactive panoramas with educational value, although the present embodiment is vulnerable to movement artifacts.

Three-dimensional vision enhances task performance independently of the surgical method

Abstract: The more complex the task, the more 3D vision accelerates task completion compared with 2D vision. The gain in task performance is independent of the surgical method.
