This affordable display system also provides various images, in addition to those from the endoscope, such as the ultrasound probe. We describe the initial experience of this system (RoboSurgeon System) in minimally invasive urologic surgeries. METHODS The display system is shown in the figure. A high definition 3D head-mounted display (Sony, Tokyo, Japan) is connected to a high-definition 3D endoscope. Various images are provided simultaneously to many participants wearing head-mounted displays. The concept of our gasless single-port surgery, performed in more than 2000 patients, has been presented at EAU and AUA (EAU2009 video V37; EAU2010 video V1, V4; AUA 2012 #1105, etc.). We present the application of this system to the initial 80 cases of gasless single-port access surgeries (16 adrenalectomies [ARs], 23 radical nephrectomies [RNs] and 41 partial nephrectomies [PNs] ). RESULTS Operations were performed by 11 surgeons including inexperienced ones without conversion to open surgery. All PNs were carried out without clamping the renal vessels as presented in EAU2010 video V4. Although the operations were performed carefully and slowly, no significant extension in operative time was required for any of the surgeries. The median operative time was 151, 184 and 214 min in AR, RN and PN, respectively. Blood transfusion was not required in any of the cases. The median blood loss was 125, 215 and 388 ml in AR, RN and PN, respectively. Clavien-Dindo grade ≥ 2 complications were only observed in two cases of PN (ureteral stenting). No worsening of starting eating / walking >100m / possible discharge was observed (AR: 1/1/1 POD; RN: 1/1/2 POD; PN: 1/2/4 POD [median]). In deep surgical sites, maneuvers can be performed safely and meticulously by sharing various images among the participants using the features of the aforementioned system. CONCLUSIONS A new 3D head-mounted display system is feasible and may facilitate maneuverability and safety in minimally invasive procedures. © 2013 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 189Issue 4SApril 2013Page: e344-e345 Advertisement Copyright & Permissions© 2013 by American Urological Association Education and Research, Inc.MetricsAuthor Information Kazunori Kihara Tokyo, Japan More articles by this author Hideki Takeshita Tokyo, Japan More articles by this author Yoh Matsuoka Tokyo, Japan More articles by this author Noboru Numao Tokyo, Japan More articles by this author Kazutaka Saito Tokyo, Japan More articles by this author Fumitaka Koga Tokyo, Japan More articles by this author Hitoshi Masuda Tokyo, Japan More articles by this author Yasuhisa Fujii Tokyo, Japan More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
