“…The learning curve for laparoscopic surgery appears longer than robotic surgery and can affect outcomes . Such variability in the level of experience and expertise of surgeons and their learning curve associated with the technique and its effect on postoperative outcomes could not be accounted in the present study.…”

Objective• To compare laparoscopic partial nephrectomy (LPN) with robotic PN (RPN) using meta-analytical techniques, since there has been a rise in the incidence of small renal masses (SRM; <4 cm) minimally invasive approaches are becoming more popular in dealing with such pathologies. Materials and Methods Results• Six studies matched the selection criteria. In all, 256 patients were analysed (40% RPN and 60% LPN). • There was no significant different in EBL (P = 0.12, 95%confidence interval [CI] -12.01 to 104.26).• Similarly, there was no significant different in WIT between the groups (P = 0.23, 95% CI -15.22 to 3.70).• Also, LOS (P = 0.22, 95% CI -0.38 to 0.09) and overall postoperative complication rates were not significantly different between the groups (P = 0.84, 95% CI -0.05 to 0.06). Conclusions• Despite multiple studies reporting better perioperative variables for RPN, the present study found no significant differences between RPN and LPN. This has implications for both the surgeon and the patient.• Lack of randomised controlled trials in addition to a lack of long-term oncological data for RPN are current limitations.

“…Such a lack of insight is regrettable, especially since AR may have a strong impact on the surgeon's attention ( Dixon et al, 2013 ), which underlines the importance of appropriate rendering and content for the augmentation. For example, disorientation has been identified as the main cause of surgical errors in laparoscopic bile duct surgery, especially due to visual illusion ( Sodergren et al, 2012 ).…”

The use of augmented reality in minimally invasive surgery has been the subject of much research for more than a decade. The endoscopic view of the surgical scene is typically augmented with a 3D model extracted from a preoperative acquisition. However, the organs of interest often present major changes in shape and location because of the pneumoperitoneum and patient displacement. There have been numerous attempts to compensate for this distortion between the pre- and intraoperative states. Some have attempted to recover the visible surface of the organ through image analysis and register it to the preoperative data, but this has proven insufficiently robust and may be problematic with large organs. A second approach is to introduce an intraoperative 3D imaging system as a transition. Hybrid operating rooms are becoming more and more popular, so this seems to be a viable solution, but current techniques require yet another external and constraining piece of apparatus such as an optical tracking system to determine the relationship between the intraoperative images and the endoscopic view. In this article, we propose a new approach to automatically register the reconstruction from an intraoperative CT acquisition with the static endoscopic view, by locating the endoscope tip in the volume data. We first describe our method to localize the endoscope orientation in the intraoperative image using standard image processing algorithms. Secondly, we highlight that the axis of the endoscope needs a specific calibration process to ensure proper registration accuracy. In the last section, we present quantitative and qualitative results proving the feasibility and the clinical potential of our approach.
