In order to achieve a three dimensional appearance to a pair of two dimensional images, two off-axis images can be produced and colorized. These can be overlayed slightly apart and then viewed through glasses with two differently colored sides, one color for the left eye and another for the right eye in combinations containing red, green or blue colors. These off-axis and colorized images are referred to as anaglyphs.Off-axis images can be achieved through the use of a tilting stage on a microscope, by physically changing the position of a camera in relation to a still object, or through changing the axis of an optical stack of sections, such as what is created by confocal/CT scans. Some images lend themselves more to a 3D look both by virtue of inherent three dimensionality limited by the resolution of the imaging system.

53 Background: Laparoscopic surgery is more challenging compared with open surgery, in part because surgeons must operate in three-dimensional (3D) space through a two-dimensional (2D) projection on a monitor, which results in loss of depth perception. To counter this problem, 3D imaging for laparoscopic was developed. However, there is limited evidence regarding its efficacy and safety. We therefore conducted a phase III, single center, prospective, randomized study to validate the efficacy and safety of 3D laparoscopic gastrectomy for gastric cancer compared with 2D laparoscopic surgery. Methods: The eligible criteria were pathologically-proven adenocarcinoma, 18 to 75 years of age, no history of other malignant tumor, chemotherapy, or radiotherapy, and clinical stage T1-4aN0-3M0 with R0 resection. The primary end point was to determine whether there is a difference in operation time between the two groups. The morbidity and mortality were compared to evaluate the safety of this trial. Results: A total of 196 patients were randomized (97 cases in 3D Group; 99 cases in 2D Group) between January 1, 2015 and August 31, 2015. There were no significant differences between the two groups in clinicopathological characteristics. The mean number of retrieved lymph nodes was similar in the 3D and 2D groups (35.6±14.1 vs. 36.1±13.5 per case). The operation time was similar in 3D and 2D groups (183.6±34.1 vs. 180.0±37.2 min). The blood loss in 3D Group was 59.6±45.6 ml, which was less than that in 2D Group (69.9±62.4 ml) without statistically different. There were no significant differences in times to resumption of activities, first flatus, resumption of soft diet, and post-operative stay between the two groups (P > 0.05, respectively). The morbidity of the 3D and 2D groups were 21.6% (21/97) and 17.1% (17/99), respectively (P = 0.428). There was no patient died during the postoperative stay in both groups. Conclusions: 3D laparoscopic gastrectomy is a safe and feasible procedure for gastric cancer. However, compared with 2D group, there was no so much benefit from 3D laparoscopic gastrectomy for gastric cancer. Clinical trial information: NCT02327481.
