“…HD imaging systems allow for the visualization of micro‐tissue structures, including small vessels. Several studies have reported that this advantage is linked to less intraoperative blood loss 11‐13 . The median estimated blood loss of laparoscopic surgery groups of previous RCTs ranged 100‐105 mL for colon cancer surgery, 2,4,6,14 which was higher than the amount of blood loss in the present study.…”

Introduction Currently, laparoscopic surgery generally relies on 2 K high‐definition image quality. The National Cancer Center Hospital, Olympus Corporation, and NHK Engineering System Inc. recently developed a new laparoscopic system with an 8 K ultra‐high‐definition (UHD) camera that provides images with a high‐resolution, wide color range, high frame rate, and high dynamic range. This study aimed to investigate the effectiveness and safety of a new laparoscopic system which uses an 8 K UHD camera system (8K UHD system). Methods This phase II study enrolled 23 patients with colon or rectosigmoid cancer who were indicated for radical resection with laparoscopic colectomy using the 8 K UHD system. The primary endpoint was the proportion of patients with ≥30 mL of intraoperative blood loss. Results Of the 23 patients, 22 completed laparoscopic surgery with the 8 K UHD system. One patient was converted to the 2 K high‐definition laparoscopic system due to technical difficulties with the 8 K UHD system during surgery. The median amount of intraoperative blood loss was 14 mL (range, 2‐71 mL), and number of patients with intraoperative blood loss ≥30 mL was four (17.4%). None of the patients had >100 mL of intraoperative blood loss. No intraoperative complications were noted, and four (17.4%) patients developed postoperative complications. Pathological complete resection was achieved in all patients, and no conversion to open surgery was required. Conclusions Laparoscopic surgery using the 8 K UHD system appears to be both safe and effective. However, further refinements may be necessary to improve usability.

“…The 3D‐laparoscopy is a good alternative for robotic surgery with equal optical conditions but less setup time and costs 9 . The novel 3D‐vision system shows also significant advantages in upper and lower abdominal surgery in the context of surgery time, blood loss, and error rates, especially in complex surgeries 27,28 …”

“…9 The novel 3D-vision system shows also significant advantages in upper and lower abdominal surgery in the context of surgery time, blood loss, and error rates, especially in complex surgeries. 27,28 Our study had several strengths and limitations. We excluded the first patients who underwent surgery in the period of the learning curve for 3D laparoscopy and sacrocolpopexy.…”

The gold standard to treat an apical pelvic organ prolapse is the abdominal route via a sacrocolpopexy, which is also reproduced by laparoscopic route. A laparoscopic sacrocolpopexy however, requires surgical expertise. Threedimensional (3D) laparoscopy has been developed to overcome the lack of depth perception, that is a known disadvantage of conventional two-dimensional (2D) laparoscopy. This procedure can accelerate the learning curve and optimize the intra-, peri-, and postoperative outcomes. This study aims to compare 3D laparoscopy to traditional 2D laparoscopy for sacrocolpopexy. Methods: Data from 132 patients who underwent a sacrocolpopexy with 2D or

“…It is noteworthy that the intention of the simulator described in the article is not to train robust or complex surgical procedures, but to direct primary learning to an unfamiliar audience, especially with regard to the manipulation of instruments and main movements, adaptation to the 2D visual-spatial field, and motor coordination practices 6 , 15 . We should also mention that the simulated training of surgical skills improves manual skills and protects the learner and the patient due to the controlled environment, reducing the risk of iatrogenic episodes 2 , 11 , 13 , 14 , 16 , 17 .…”

Objectives: to describe the construction of a low-cost laparoscopy training simulator and evaluate its level of acceptance, impact on learning, and skill development in medical students. Methods: we built a video training simulator using low-cost materials. We then carried out a cross-sectional study, with the use of an applied questionnaire to medical students. Results: 51 medical students participated in the research, of whom 76.47% gained confidence in relation to laparoscopic surgery, 100% stated that the model successfully trained the skills of motor coordination and two-dimensional visual-spatial field, in addition to enabling a greater understanding of laparoscopy. All agreed that the simulator should be used before a real laparoscopic surgery scenario. Conclusion: the construction of the described laparoscopic surgery training simulator proved to be feasible and effective as an educational resource. It was well accepted by medical students, with easy handling, and promoted the development of motor and visual skills in video surgery.
