“…A recent study comparing the 3D high definition with 4 K (ultra-high definition) imaging showed that there is no decrease in operating time and errors during laparoscopic cholecystectomy with 3D imaging system. 16 Our research found that difficulty in re-imaging from one distance to another showed the importance of eye strain and headache in 3D imaging. While eye strain was found to be statistically significant in 2D.…”

Objective: To compare the short-term outcomes of three dimensional (3D) versus two dimensional (2D) laparoscopic procedures used for cholecystectomy. Methods: This study was conducted at minimally invasive surgery center of Liaquat University of Medical Health and Sciences (LUMHS) Jamshoro Pakistan, between 15th May 2017 to 16th December 2017 after taking informed consent. All patients were diagnosed cases of cholelithiasis without any complications. Patients having risk factors for inability to get access to gall bladder via laparoscope and in whom the chances of conversion to open cholecystectomy were greater were not included as part of study. One group of patients underwent cholecystectomy under 3D laparoscopy while other group underwent 2D laparoscopy. Surgeons included in the study were all well-trained. The short-term outcome noted were intraoperative and postoperative complications, conversion to open, operative time, mortality and hospital stay. Visual strain and headache for the surgeon in three D laparoscopic cholecystectomy. Results: A total of one hundred forty patients were included in the study. Group-A consists of sixty two females and eleven males whereas Group-B comprised of fifty eight females and fifteen males. Eight percent of patients in Group-A whereas in Group-B two percent had gallbladder rupture. Fifteen percent of patients in Group-A whereas 5.4% from Group-B had bleeding from liver bed. One patient from Group-A had CBD (Common Bile Duct) injury. Post-operatively two (2.73%) patients from Group-A had port site bleeding. Six (8.21%) patients had port site infection in Group-A. Conclusion: Three dimensional was found to have low incidence of intra-operative and post-operative complications compared to 2D laparoscopic cholecystectomy. doi: https://doi.org/10.12669/pjms.37.1.3721 How to cite this:Shaikh AR, Shaikh AA, Abbasi M.

“…In a clinical trial in 109 laparoscopic cholecystectomies, performed by 3 consultant surgeons, neither operative time (23 minutes vs 21 minutes) nor the number of mistakes (60 vs 58) were influenced by the 3D or 4K technique. 22 This operative setting might not be challenging enough due to static preparation in Calot triangle combined with experienced surgeons to discriminate an effect between one of the high-end display systems. In certain situations 4K technique might be beneficial: Harada et al compared minimally invasive suturing tasks performed by expert laparoscopic surgeons and saw an improved surgical performance with the 3D compared to 4K, but in narrow spaces with low grades of instrument movement 4K and 3D were comparable.…”

Objective: To evaluate if “state-of-the-art” 3D- versus 4K-display techniques could influence surgical performance. Background: High quality minimally invasive surgery is challenging. Therefore excellent vision is crucial. 3D display technique (3D) and 2D-4K technique (4K) are designed to facilitate surgical performance, either due to spatial resolution (3D) or due to very high resolution (4K). Methods: In randomized cross-over trial the surgical performance of medical students (MS), non-board certified surgeons (NBC), and board certified surgeons (BC) was compared using 3D versus 4K display technique at a minimally invasive training Parkour. Results: One hundred twenty-eight participants were included (February 2018 through October 2019, 49 MS, 39 NBC, 40 BC). The overall Parkour time (s) 3D versus 4K was 712.5 s ± 17.5 s versus 999.5 s ± 25.1 s ( P < 0.001) for all levels of experience. It was (3D vs 4K) for MS (30 tasks) 555.4 s ± 28.9 s versus 858.7 s ± 41.6 s, ( P < 0.0001), for NBC (42 tasks) 935.9 s ± 31.5 s versus 1274.1 s ± 45.1 s ( P =< 0.001) and for BC (42 task) 646.3 s ± 30.9 s versus 865.7 s ± 43.7 s ( P < 0.001). The overall number of mistakes was (3D vs 4K) 10.0 ± 0.5 versus 13.3 ± 0.7 ( P < 0.001), for MS 8.9 ± 0.9 versus 13.1 ± 1.1 ( P < 0.001), for NBC 12.45 ± 1.0 versus 16.7 ± 1.2 ( P < 0.001) and for BC 8.8 ± 1.0 versus 10.0 ± 1.2 ( P = 0.18). MS, BC, and NBC showed shorter performance time in 100% of the task with 3D (significantly in 6/7 tasks). For number of mistakes the effect was less pronounced for more experienced surgeons. The National Aeronautics and Space Administration-task load index was lower with 3D. Conclusion: 3D laparoscopic display technique optimizes surgical performance compared to the 4K technique. Surgeons benefit from the improved visualization regardless of their individual surgical expertise.

“…Imaging systems for endoscopic surgery have made remarkable progress, and not only full high-definition (HD) but also 4 and 8 K systems can be introduced into laparoscopic surgery. 4,5 Furthermore, observations using enhancement and near-infrared fluorescence imaging have been developed. 6 For example, the usefulness of observation for peritoneal disseminated lesions using narrow-band imaging (NBI) in combination with normal observation has been reported.…”

Introduction: The indication of laparoscopic gastrectomy for advanced cases such as serosal invasion or peritoneal dissemination is still controversial. We report the clinical experiences of laparoscopic diagnosis with image enhancement and autofluorescence (AF) systems for laparoscopic gastric cancer surgery. Methods: The image enhancement system was introduced to 164 patients who underwent laparoscopic gastric cancer surgery as the AF group. The control group was defined as 165 cases who underwent bright light observation without the image enhancement system. The operative findings were recorded during surgery. All image findings were retrospectively compared with the pathological findings. Furthermore, the relationship between the image and pathological findings for peritoneal dissemination and subserosal invasion was evaluated.Results: This study included 329 patients, divided into the control group of 165 patients (50.2%) and the AF group of 164 patients (49.8%). There was no statistically significant difference in patient background between the two groups. In seven cases of peritoneal dissemination, AF was positive, and macroscopic abnormal vascularization was detected. The sensitivity, specificity, and positive and negative predictive values were 100%, 99.4%, 87.5%, and 100%, respectively. In 29 cases of serosal invasion, AF was positive, and macroscopic abnormal vascularization was detected. In the detection accuracy of subserosal invasion, the sensitivity, specificity, and positive and negative predictive values were 75.7%, 97.6%, 90.3%, and 93.2%, respectively. Conclusion:The image enhancement with the AF system is useful for the laparoscopic intraoperative diagnosis of serosal invasion and peritoneal dissemination for advanced gastric cancer.
