First clinical results of the da Vinci Sp Single Port device


A novel article is under publication in the European Urology about the very first clinical trials of the da Vinci single port robot. The  surgical  procedures  were done  during  a  3-week-long  period  in  July  2010  at  Lille  Regional  Hospital  Center in France.

"Objective:  To  determine  the  clinical  feasibility  and  safety  of  single-port  urologic  procedures  by  using a  novel  robotic  surgical  system.
Design,  setting,  and  participants:  This  was  a  prospective  institutional  review  board–approved, Innovation,  Development,  Exploration,  Assessment,  Long-term  Study  (IDEAL)  phase  1  study.  After enrollment,  patients  underwent  a  major  urologic  robotic  single-port  procedure  over  a  3-wk  period  in July  2010.  The  patients  were  followed  for  3  yr  postoperatively.
Intervention:  Different  types  of  urologic  surgeries  were  performed  using  the  da  Vinci  SP  Surgical System.  This  system  is  intended  to  provide  the  same  core  clinical  capabilities  as  the  existing multiport  da  Vinci  system,  except  that  three  articulating  endoscopic  instruments  and  an  articulating endoscopic  camera  are  inserted  into  the  patient  through  a  single  robotic  port.
Outcome  measurements  and  statistical  analysis:  The  main  outcomes  were  the  technical  feasibility  of the  procedures  (as  measured  by  the  rate  of  conversions)  and  the  safety  of  the  procedures  (as measured  by  the  incidence  of  perioperative  complications).  Secondary  end  points  consisted  of evaluating  other  key  surgical  perioperative  outcomes  as  well  as  midterm  functional  and  oncologic outcomes.
Results  and  limitations:  A  total  of  19  patients  were  enrolled  in  the  study.  Eleven  of  them  underwent radical  prostatectomy;  eight  subjects  underwent  nephrectomy  procedures  (partial  nephrectomy, four;  radical  nephrectomy,  two;  and  simple  nephrectomy,  two).  There  were  no  conversions  to alternative  surgical  approaches.  Overall,  two  major  (Clavien  grade  3b)  postoperative  complications were  observed  in  the  radical  prostatectomy  group  and  none  in  the  nephrectomy  group.  At  1-yr follow-up,  one  radical  prostatectomy  patient  experienced  biochemical  recurrence,  which  was successfully  treated  with  salvage  radiation  therapy.  The  median  warm  ischemia  time  for  three  of the  partial  nephrectomies  was  38  min.  At  3-yr  follow-up  all  patients  presented  a  preserved  renal function;  none  had  tumor  recurrence.  Study  limitations  include  the  small  sample  and  the  lack  of  a control  group.
Conclusions:  We  describe  the  first  clinical  application  of  a  novel  robotic  platform  specifically
designed  for  single-port  urologic  surgery.  Major  urologic  procedures  were  successfully  completed without  conversions.  Further  assessment  is  warranted  to  corroborate  these  promising  findings."

Report from IEEE ICRA -- part2



The obvious rise of medical robotics was witnessed at IEEE ICRA. (Check the first part of the report here.) This year, we have even seen parallel medical robotics sessions running at the conference, and the overall large number of CIS related papers (75+ with the keyword medical robot ) gave a huge challenge to people who wanted to check them all. Let us give a little overview of what trends are emerging, based on the sessions:

Quiz #9


Solution for our last, Quiz#8 was the Titan's SPORT system current prototype. (Learn more about it here.) We received a kind-of correct solution from "crazymerkz"--congratulations!
Next one: which system can be seen above? You can submit your answers to surgrob.blog at gmail.com until August 30.
