“…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.

“…Some studies have proven that very experienced surgeons can compensate for the lack of stereo perception inherent in 2D systems 7, 8. Nevertheless, several studies have shown that 3D endoscopic systems are superior to 2D systems, especially when involving complex operations, and for less experienced surgeons 6, 9, 10, 11, 12, 13. Our surgeon reported that the 3D system provides a better sense of depth, which can facilitate precise tasks, such as suturing.…”

“…The same surgeon, who was experienced in 2D VATS lobectomy, but relatively less experienced in the use of 3D systems, performed all operations. Because of his extensive experience, the surgeon could compensate for the limitations of the 2D system by using 2D cues, such as light and shade, the relative size and position of tissues and organs, texture gradient, spatial perspective, and motion parallax 6. Some studies have proven that very experienced surgeons can compensate for the lack of stereo perception inherent in 2D systems 7, 8.…”

“…Surgeons can perform complex tasks, such as suturing or ligation, more quickly and precisely 12. Complex operations, such as bronchial or vessel sleeve resection, are performed more easily and surgical duration is shorter 6. Surgeons, particularly beginners, need not adapt the conversion from stereoscopic vision to 2D vision, so they can learn to perform VATS more easily and more rapidly.…”

BackgroundThe advantages and disadvantages of three‐dimensional (3D) and two‐dimensional (2D) two‐port video‐assisted thoracoscopic surgery (VATS) lobectomy and systematic dissection of mediastinal lymph nodes for lung cancer were investigated.MethodsBetween December 2013 and July 2015 at Beijing Hospital, 191 patients underwent lobectomy and systematic dissection of mediastinal lymph nodes for lung cancer. After applying the study criteria, a total of 165 patients were included and allocated to 3D (n = 76) and 2D (n = 89) groups. Variables of the study design, including duration of surgery, volume of intraoperative bleeding, numbers and groups of lymph nodes dissected, drainage volume after surgery, duration of drainage tube insertion, hospitalization time after surgery, hospitalization costs, and complications, were recorded and analyzed. Intergroup differences for all data were compared and statistically analyzed.ResultsNo statistical difference was found between the two groups with respect to duration of surgery, volume of intraoperative bleeding, drainage volume after surgery, duration of drainage tube insertion, hospitalization time after surgery, hospitalization costs, and complications (P > 0.05). Additionally, there was no significant difference in the numbers and groups of all lymph nodes or N 2 lymph nodes resected (P > 0.05).ConclusionLobectomy with systematic lymph node dissection can be undertaken with two ports using a 3D thoracoscope, and presents similar results to the use of a traditional 2D thoracoscope, at no greater hospitalization cost but with better operational perception and sensitivity during surgery. Two‐port lobectomy with systematic lymph node dissection using a 3D thoracoscope is a safe and effective surgical process for lung cancer treatment.

“…Robotic systems such as the 'da Vinci' offer several advantages when compared to standard laparoscopy including: (i) increased fine manual dexterity with motion scaling and tremor stabilisation; (ii) improved ergonomic position, aiding the surgeons' comfort by allowing them to operate from a seated position and (iii) improved visualization with image stereopsis (Kwok, et al, 2012;Rockall and Darzi, 2003). The benefit of the three-dimensional video-imaging systems in MIS has been proved under different experimental conditions (e.g., (Kong, Oh et al 2010;Storz, et al 2012)). The main drawbacks of the Da Vinci system are its high cost and the high training required to the surgeons to use this device.…”
